Chapter 1 - INTRODUCTION

The following information was developed by the Pennsylvania Turnpike Commission (PTC) to be

used as a set of guidelines in the design of Total Reconstruction projects. These guidelines will be periodically updated to reflect the most current design decisions and information related to thesetypes of projects.

The information included herein will not be applicable to every project. Each project is to bedesigned on an individual basis, taking into account all applicable information included herein, yet

making decisions using sound engineering judgment based on the unique aspects of each project.

PennDOT standards and publications, AASHTO design guidelines and Commission specifications

and standards should all be used in conjunction with these guidelines in design. It is understood

that federal, state or local regulations may require deviations from these guidelines.

It is the mission of the Commission to operate and manage a safe, reliable, cost-effective and

valued toll road system and in cooperation with our Consultants, our mission will be

accomplished.

FOR SECURITY PURPOSES, ANYONE THAT INTENDS TO MAKE A FIELD VISIT ON

TURNPIKE DESIGN PROJECTS MUST NOTIFY THE APPROPRIATE

MAINTENANCE FACILITY IN ADVANCE OF THE FIELD VIEW. OBTAIN THE

MAINTENANCE FACILITY CONTACT INFORMATION FROM THE TURNPIKE

PROJECT MANAGER AT THE START OF THE PROJECT.

Prior to Working within the PTC Right-of-Way 

Consultants doing any work on Turnpike R/W (surveyors, drillers, utilities, R/W personnel

environmental specialists, etc.) should inform the PTC project manager prior to performing the

work.

The following information should be provided:

•  location of work (mileposts)•  make, year, and model of vehicle(s)

•  color of vehicle(s) and markings

  state in which registered and license tag number(s)•  Contact information (including phone number) for responsible office parties

•   Number of workers to be on-site

•  Field contact name and information - with cellular number 

•  Brief scope of work - impact (working on shoulders, off roadway, etc.)

•  general timeframe

(The PTC PM will provide this information to the Duty Officer at the Operations Center.) On each

day of work the consultant should telephone the Duty Officer at the Operations Center at 866-332

5889 or *11 by cellular and ask for the Duty Officer. He will need the location and vehicle

description along with a telephone number for contact. (They keep a log of those on the PTCsystem so that they know who is where and what they are doing.)

Following these procedures is important because it prevents conflicts with ongoingMaintenance Department activities, conflicts with activities by other Consultants, andallows the PTC to notify appropriate parties and hopefully keep you from beingchallenged by the PA State Police.

Chapter 2 – SURVEYS

2.0 Introduction

Engineering surveys shall be performed according to methods and practices outlined in PennDOT

Publication 122M (Surveying and Mapping Manual) except as directed by this section, and any project specific directives issued by the Commission, in writing.

All surveys are to be based upon the “U.S. Survey Foot” definition, and NOT to be based upon the

“International Scientific Foot” definition. Any metric / U.S. Survey Foot conversions of data areto utilize the “1200 / 3937” ratio.

2.1 Survey/Plan Requirements for GPS Utilization 

The goal of this section is the establishment of a network of vertical and horizontal control pointsto support the Final Design surveying and utilization of GPS survey equipment by the Contractor

for each construction section. The network will also support conventional survey methods for

Contractors who do not intend to utilize GPS equipment on projects defined as “Minor Projects”and “Small Bridges/Structures” in Section 2.3 A.

A. Control/Monument Recovery

The Final Design Consultant shall recover all available horizontal and vertical control

 points shown in field notes, mapping control reports, record of control data sheets, and

 plans provided by the Commission. This recovery shall include control points adjacent to

the project, on adjoining sections, with the intent of utilizing adjacent projects’ control tocreate a seamless connection with the adjoining sections.

B. Evaluation of Control for Final Design and Construction Control 

The Final Design Consultant for “Minor Projects” and “Small Bridges/Structures” shal

evaluate their section for a GPS Permanent Control Network to support Final Design

surveying and construction. A GPS Permanent Control Network is required for “MajorProjects” and “Major Bridges/Tunnels”. The requirements for control of construction

 projects are defined in Section 2.3. Location, condition, stability, and spacing of recovered

survey control points is to be reviewed to determine suitability as safe (out of jeopardy of

destruction from future construction activities) and usable points for the duration oconstruction. If the evaluation of the available horizontal and vertical control is determined

to not meet the requirements outlined in Section 2.3, densification / augmentation of thecontrol network as described in Section 2.3 is necessary.

Page 16: pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 16/208

Oct 2011

The horizontal position of the monuments will be established by static GPS observationsOffsite static stations should be included in the GPS observations as necessary to ensure

strong geometric figures for network adjustments. Incorporate primary control monumentsfrom adjacent design sections in the adjusted network to attempt to provide a seamless fiwith existing projects. The vertical position of the augmentation monuments will be based

upon the same datum (NAVD 1988 for extended NGS Monuments) utilized for thePrimary Control Mapping Monuments.

Plans to add any additional permanent control points to the section shall be submitted to the

Design Manager and Commission Surveyors for review (if applicable). Additiona

 permanent vertical and horizontal control monuments and supplementary permanen benchmarks shall be constructed as specified in the PTC Standard Special Provisions.

Except for “Minor Projects” and “Small Bridges/Structures” as defined in Section 2.3-A, aminimum of two pairs of inter-visible concrete monuments (as defined below) per designsection shall be required along the right-of-way so as to provide a network of points for theutilization of GPS survey equipment.

Projects in Section 2.3 must be in Project Grid Coordinates derived from Pa. State PlaneCoordinates, N.A.D. 83, with the Combined Grid Factor provided. Projects in Section 2.3

A should be evaluated to determine if they should be in a Project Grid or State Plane

Coordinate System. See the Project Manager for further clarification.

An “Inter-visible Monument Pair” consists of two poured-in-place concrete monuments

(each of the monuments to be constructed per guidelines in the “Horizontal Control Discs”Commission Standard Special Provision) set between eight hundred (800) feet and twenty-

five hundred (2500) feet apart. Monuments are to be GPS accessible, and set near the

right-of-way fences in stable ground. Ideally, monuments should be located so they are se

at or near proposed roadway grade at places of transition from cut (excavation) to fill(embankment) so they are easily accessible by surveyors and not prone to disturbance from

future construction activities.

A “Vertical Control Monument” is a poured-in-place concrete monument (“Benchmark

Disc” as described in Commission Standard Special Provisions).

A “benchmark” is a firm and vertically stable object (chiseled corner of a concrete

structure, railroad spike driven horizontally into tree, chiseled fire hydrant bolt, etc.

capable of holding an elevation. The object should be able to be occupied by leveling rod digital bar staff. Benchmarks should be located beyond the limits of disturbance fromconstruction activities.

A “Horizontal Control Re-bar” is a three-quarter inch (3/4”) diameter number six (6) re-barthirty inches (30”) long. The re-bar is to have no plastic cap, driven flush with the ground

and is to be punched or drilled so it has a defined center. The re-bar should be GPS

accessible, and set near the right-of-way fence in stable ground. Avoid placement in fil(embankment) areas, if possible. Ideally, re-bars should be located so they are set at o

near proposed roadway grade at places of transition from cut (excavation) to fill(embankment) so they are easily accessible by surveyors and not prone to disturbance fromfuture construction activities. An orange fiberglass marker post approved by the

Commission shall be placed against the right-of-way fence so it is radial / perpendicular to

the Survey and Construction Baseline at the station of the re-bar.

C. Verification Of Mapping Accuracy 

Final Design Consultant is to perform a Map Accuracy Tests in accordance withPublication 122-M and as follows:

Final Design Consultant shall obtain three or more test profiles. Each test profile should bea minimum of one thousand (1000) feet in length and spaced evenly throughout the project

There should be a minimum of twenty-five (25) feet elevation differential in each profile

over its 1000 foot length. Test profiles are to be taken in tangent (not curved) areas (i possible), along the roadway’s edge of lane where mapper created a break line in the T.I.N

Profile elevations will be taken (utilizing conventional surveying or Real Time Kinematic

(R.T.K.), Geographical Positioning System) at intervals not exceeding fifty feet (50’) and

will include a minimum of two mapping control points for each profile (either primarycontrol monuments or mapping panel points).

Final Design Consultant shall obtain three or more mapping test cross-sections. Eachcross-section should include edges of roadways, edges of shoulders, lane lines, breaks in

grade, and at least two mapping panel points as a check.

The points selected shall be compared to the elevations extracted from the mapping Digita

Terrain Model as supplied by the Commission and the differences for each elevation

summarized and submitted for test profiles and cross sections.

Occupy all Primary Control Monuments with total station survey instrument and obtain

horizontal distances to three nearby mapping panel points. Field-derived inverse distances

shall be compared to coordinate inverse distances and results summarized and submitted.

Obscured areas (shadows, structures, heavy ground cover, etc) require topographic field

survey to augment mapping.

Traverses and data collection performed to augment aerial mapping should be checked

against the mapping for inconsistencies. Significant differences in areas not indicatedobscured will warrant additional test sections.

The GPS network shall tie into the existing mapping control points.

2.2 Surveys for Supplementing Project Mapping

Final Design Consultant is to extend Project Mapping Control to collect all information necessary

Baseline Referencing

Baselines shall be staked at limits of work, endpoints of all tangents (PIs if accessible) andon long curves and tangents at intervals of no farther than six hundred (600) feet apart

Description of point (P.C., P.T., T.S., etc.) and stationing shall be marked upon the stake or

 pavement, as appropriate. Additional baseline points shall be set as necessary to ensure a

clear line of sight between adjacent baseline points. Each baseline point shall be

referenced by using no less than three durable, recoverable, ferrous objects or drill holes /chisel cuts in stable concrete objects, the references each being at least as far apart as the

closest reference is to the baseline point being referenced. Final Design Consultant shal

 provide both the distance and angular relationships between the references and the baseline

 point being referenced. When setting references, care should be taken to consider future

construction activities and if possible, references should be placed beyond the limits of

 planned construction disturbance. In areas of significant cut or fill (10 feet or more) it is preferable to reference baseline points at or near transition grade from cut to fill instead of

P.C.s and P.T.s (even if in curves) to avoid baseline points and references from being

disturbed by construction and making them more easily accessible by surveyors from

roadway grade.

Random Horizontal Control Traverse Network 

As an alternative to the above, after review by Commission Surveyors, in congested or

restricted areas, the Commission will permit a “Random Horizontal Control Traverse

 Network” to be established. Randomly-placed durable ferrous inter-visible traverse points

clearly identified (marked stakes or paint) with traverse point number, shall be set in areasout of jeopardy of destruction from construction activities. Fiberglass witness marker post

(approved by the Commission) shall be set adjacent to the traverse points (or paint placed,

if applicable). A closed horizontal traverse network (point locations submitted to theCommission for review) shall be established from the primary project control monuments

The traverse shall be adjusted by least squares, shall meet a closure precision ratio of no

less than one to ten thousand (1:10,000) for “Minor Projects” and no less than one to

fifteen thousand (1:15,000) for “Small Bridges/Structures”, and a printout of the raw field

data, closure ratio, and adjustment performed shall be submitted to Commission Surveyors

for review. If applicable, a Project Grid coordinate system shall be used, and the

coordinates of the traverse points, Right-Of-Way corners, all baseline change in direction

 points and ends, and primary control monuments shall be presented upon the construction plans.

Baseline Stakeouts

In areas where proposed alignment deviates significantly from the existing roadway

footprint and new roadways, lath or painted points (as applicable) shall be placed on

 baselines at two-hundred (200) foot intervals to support field view orientation during the

in Section 2.1-B) for construction at a maximum of one thousand (1000) foot intervals two(2) near each bridge and arch/box culvert, and located beyond the limits of disturbance. As

an alternative to the thousand foot intervals described above, the Final Design Consultant

after review by Commission Surveyors, may utilize the Random Horizontal Traverse Network points for construction benchmarks.

For “Small Bridges/Structures” the Final Design Consultants shall establish two (2)

“benchmarks” on stable, rod/digital bar staff accessible points near each bridge andarch/box culvert, and located beyond the limits of disturbance.

B.  Projects Defined as “Major Projects”

Primary Mapping Control, shall be the backbone of the vertical and horizontal contro

networks for the project. Inter-visible Monument Pairs should be spaced no farther than

two and one half (2 1/2) miles apart throughout the length of the project. Existing Intervisible Monument Pairs established for adjacent projects should be incorporated to make aseamless transition with adjacent projects.

To densify the horizontal control network, “Horizontal Control Re-bars” as defined in

Section 2.1-B should be set in between Inter-visible Monument Pairs. Place HorizontaControl Re-bars so the distance to the closest monument from an Inter-visible MonumentPair is no farther than one and one half (1 1/2) miles.

Additional Survey Control for Construction

At roads with overhead bridges crossing over mainline Turnpike, Final Design Consultanshall set no less than three (3) thirty-inch (30”) long inter-visible five-eights-inch (5/8”)

diameter (no. 5) re-bars flush with the ground. Re-bars shall have no plastic caps, shal

have punched or drilled center points, shall be placed at stable locations no farther than five

hundred (500) feet apart, out of jeopardy from construction activities. It is preferable (i possible) to avoid placing re-bars in embankment (fill) areas. Final Design Consultan

Baseline Stakeouts

In areas where proposed alignment deviates significantly from the existing roadway

footprint and new roadways, lath or painted points (as applicable) shall be placed on baselines at two-hundred (200) foot intervals to support field view orientation during the

 bid phase. Where it is not practical to set baseline lath, an appropriate offset line(preferably parallel/concentric with the baseline) shall be established with stations, offsets

and whether the line is left or right of the baseline.

Consultant should stake out baseline for all side roads.

Chapter 3 – ROADWAY DESIGN

3.0  Introduction 

There are many factors that contribute to the decisions required in applying the geometric

design elements within a given design project. This chapter presents the basic framework of the design guidelines required to tailor a consistent roadway network.

Additional sources of information to supplement these design guidelines and relatedconcepts are contained in, but not limited to, AASHTO’s “A Policy on Geometric Design

of Highways and Streets”; PennDOT Publication 13M, Design Manual Part 2  – Highway

Design; PennDOT Publication 70M, Guidelines for Design of Local Roads and Streets;

PennDOT PublicationRR-441, Access to and Occupancy of Highways by Driveways and Local Roads;

PennDOT Publication 72M, Roadway Construction Standards; and the Pennsylvania

Turnpike Commission Standards for Roadway Construction.

3.1 Mainline Typical Sections  – Flexible Pavement

The typical sections for mainline were developed for two scenarios:

  Six-lane section

  Four-lane section with future lane addition in median

On new construction or reconstruction projects having a flexible pavement, the roadway

 pavement structure shall extend two feet into the outside shoulder area. Locate the

 pavement base drain at this point. The widened portion of the pavement should be

constructed at the same slope as the pavement, and the shoulder slope should begin at theedge of the widened pavement. Label all cross-slopes as a percentage (%).

On the typical section, show both the total width of the travel lanes and shoulders as well as

the width of the pavement section. For areas with two travel lanes, this would consist of a24-foot and 12-foot dimension for travel lanes and outside shoulder, respectively, and a 36-

foot and 12-foot dimension for travel lanes and outside shoulder where there are three

travel lanes. The pavement structure widths will also be shown on the typical section.Show a two-foot dimension for the extension of the pavement structure into the outside

shoulder area.

On the plan sheets, show only the total width of the travel lanes (24 foot or 36 foot),median, and shoulders (12 foot), not the width of the pavement structure.

A.  Six-lane Section Figures 3.1.1, 3.1.2, and 3.1.3 depict the typical sections for the six-lane tangent, six-

lane superelevated (2% < SE < 6%), and six-lane superelevated (SE > 6%) scenarios,

respectively.

Figure 3.1.2 illustrates a superelevated section (2% < SE < 6%). This section

introduces a graphic grade profile on the low side of superelevation so that a profile

elevation adjustment can be made to ensure that the edges of median elevations areequal. Superelevation Table 1 depicts the elevation adjustments for the simple curve

 portion of a spiraled curve or a circular curve. Further explanation of the graphic

grade profile can be found in Section 3.3.

Figure 3.1.3 illustrates a superelevated section (SE > 6%). This section also utilizes a

graphic grade profile on the low side of superelevation and introduces a change in

cross-slope transition on the low side inside shoulder and a four-foot rounding on thehigh side outside shoulder 50 feet prior to the SE = 6%. Superelevation Table 2

depicts the elevation adjustments as described in Superelevation Table 1, but for SE >

6%.

B. Four-lane Section with Future Lane Addition in Median

Figures 3.1.4, 3.1.5, and 3.1.6 depict the typical sections for the four-lane tangent,four-lane superelevated (2% < SE < 6%), and four-lane superelevated (SE > 6%)

scenarios.

Figure 3.1.4 illustrates two tangent (Normal Crown) sections with the PG (ProfileGrade) located at the edge of roadway, which under the future six-lane section will be

 between the inside and middle travel lanes.

Figure 3.1.5 illustrates a superelevated section (2% < SE < 6%). This section

introduces a graphic grade profile on the low side of superelevation so that a profile

elevation adjustment can be made to ensure that under the future six-lane section, the

edge of median elevations are equal. Superelevation Table 1 depicts the elevationadjustments for the simple curve portion of a spiraled curve or a circular curve.

Further explanation of the graphic grade profile can be found in Section 3.3.

Figure 3.1.6 illustrates a superelevated section (SE > 6%). This section also utilizes a

graphic grade profile and introduces a change in cross-slope transition on the low side

inside shoulder and a four-foot rounding on the high side of a superelevated shoulder 50 feet prior to the SE = 6%. Superelevation Table 2 depicts the elevation adjustments

as described in Superelevation Table 1, but for SE > 6%.

The four-lane section will provide a grass median with a swale located at the baseline.The details regarding type of guide rail and cross-slope design is still currently being

researched, and further direction will be given in the future.

3.2 Horizontal Alignment - Mainline

Horizontal alignments are to follow PennDOT Publications and AASHTO guidelines except whecriteria within these guidelines supersede those manuals.

A. 

Maximum Degree of Curvature

The maximum degree of curvature for mainline horizontal alignment shall not exceed

3°00'00".

B.  Spirals

Spirals shall be used on all mainline curves with a Degree of Curvature of 1°00'00" or 

greater. See note on Page 3-3, Figure 3.1.2.

C.  Guidelines for Setting Bearings and Angles

  The bearings of proposed roadways shall be set to seconds of a degree withoutdecimals.

  Bearings that tie into an existing roadway may be set to decimals of a second but is norecommended or encouraged.

  Bearings of an existing roadway may be set to decimals of a second but it is notrecommended or encouraged.

  Angles between proposed baselines should be set to seconds of a degree withoutdecimals.

  Angles shown in the curve data should produce the bearings shown for the roadway,

and the roadway bearings should produce the curve data angle.

D.  Plan Presentation

The construction plans for both Early Action Projects and the Mainline

Total Reconstruction require Right-of-way/Geometry Plans indicating the

tie between the Original Right-of-way Baseline and the Survey andRight-of-Way Baseline.

2. Curve Data Presentation

Horizontal curve data shall be presented as indicated in Figure

3.2.1 or Figure 3.2.1.A. Presentation shall be consistent throughout the

 plans.

3.3 Vertical Alignment – Mainline

Vertical alignments are to follow PennDOT Publications and AASHTO guidelines exceptwhere criteria within these guidelines supersede those manuals.

A. 

Maximum Percent Grade

The desirable maximum percent grade is 3%. Steeper grades can be investigated

due to topography or other conditions that may justify the use of steeper grades and

must be approved by the Commission.

B.  Guidelines for Setting Profile Grades and Elevations

  PI stationing should be at a +25-foot interval, when possible, and decimals in thePI stationing are discouraged.

   Normally, all grades are to be set and shown to two (2) decimal places.

 

When tying into an existing roadway, three (3) decimal places for the tie-ingrade may be used.

  Grades can be rounded provided the rounded grade produces no change to theelevations of the established or set points (PVI station and elevation).

EXAMPLE: 17.18' (set difference in elevation)/480' (distance between PI’s) =.03579 (3.5792%) = 3.58%. Grade is to be used.

CHECK: .0358 (3.58%) x 480' = 17.184' and rounds to the set difference in

elevation of 17.18'.

  Elevations can be rounded provided the rounded elevation produces nochange to the grade.

  All PVI elevations are to be established using the rounded elevation of the back PVI.

  PG elevations at any point along the survey and construction baselineare to be established using the rounded elevation of the PVI and the

rounded grade.

EXAMPLE: 3.58% (set grade) x 480' = 17.184' ~ 17.18' is to be used.

CHECK: 17.18' / 480' = .03579 (3.579%) which rounds to the set

grade of 3.58%.

C.  Guidelines for Setting Graphic Grade Profiles and Elevations

As described and depicted in Section 3.1, Typical Sections, the low side of a superelevat

curve will have a graphic grade to adjust the profile elevations so that the edge of medi barrier elevations are equal in fully superelevated sections and within three (3) inches

transition areas.

  A maximum of three inch reveal and a minimum of zero (0) inch reveal must

maintained on the concrete glare screen throughout.

Graphic Grade Elevation Calculations in Full Superelevation

  The Graphic Grade elevations will be determined utilizing the concepts depicted Figures 3.1.2 and 3.1.3 for the six-lane mainline section and in Figures 3.1.5 and 3.1for the four-lane mainline section with future lane addition in median. This consta

elevation adjustment, (GG, will provide a three (3) inch reveal on each side of tconcrete glare screen within a fully superelevated section.

Graphic Grade Elevation in Transition Areas

  Since a constant elevation adjustment, (GG, will occur in a fully superelevation curva transition from the profile grade to the PC or SC is needed. The following guidelin

are to be used for spiraled curves and simple curves.

Spiraled Curves 

  Provide linear transitions from the profile grade to the constant elevation adjustmen

GG between the TS and SC stations entering the curve and from the CS to ST statioexiting the curve.

Circular Curves

  Provide linear transitions from the Profile Grade to the constant elevation adjustmenGG between the (PC-L), Where L = Length of Superelevation Runoff, and the P

station entering the curve and from the PT to (PT+L) station exiting the curve.

  It is the designer’s responsibility to evaluate profiles along the edge of roadway toavoid rapid grade changes and to ensure a smooth graphic profile.

  Figures 3.3.1 and 3.3.2 depict how the aforementioned Graphic Grade Transitionsoccur for the example horizontal curve data provided in Figure 3.2.1.

D. 

Plan Requirements

  Provide one mainline profile depicting the Profile Grades and Graphic Grades inaccordance with Figure 3.3.1. Provide Profile Grades at 50 foot intervals. Provide

Graphic Grades at 25 foot intervals in Transition Areas and at 50 foot intervals in

constant elevation adjustment, GG areas. The existing elevations depicted on thesingle profile will be along the profile grade points.

  Follow guidelines in Section 3.3.B when applicable.

  At locations where tying to existing conditions, set and tie one direction as ProfileGrade, tie the opposite direction as Graphic Grade Transition Area, and label as per

Figure 3.3.1.

  Show clearances to all structures and overhead utilities.

3.4 Superelevation Transition and Spiral Lengths

  As per typical sections presented in Section 3.1, use current PennDOT Publication 13M,

Design Manual Part 2  – Highway Design, for determining minimum superelevation transition

(T), Minimum Tangent Runout (X), Minimum Superelevation Runoff (L), and MinimumSpiral Lengths (LS).

  Values shown in DM2 for minimum superelevation runoff (L) and minimum spiral length (Ls)should be adjusted to the next highest even multiple of ten feet (10’). The tangent runou

length (x) should also be adjusted to provide a linear transition rate from normal crown to fullsuperelevation using the value established for L or Ls as a basis.

  Figure 3.4.1 illustrates the superelevation transitions for the same horizontal curve data presented in Figure 3.2.1.

3.5 Cross-sections

  Provide mainline cross-sections at 50 foot intervals and as required depicting unique features.

  Partial cross section inserts to adequately show proposed storm drainage shall be provided

when deemed necessary by the design manager, the project manager or as determined by the

designer.

  Provide 4:1 or flatter fill slopes when economically feasible. The use of 3:1 fill slopes shall beavoided unless in transition areas.

  Provide pavement base drain as the subbase drainage outlet for all fill slopes flatter than 2:1.

Chapter 4 – MAINTENANCE AND PROTECTION OF TRAFFIC

4.0 Introduction

The Maintenance and Protection of Traffic Plan (MPT) is to provide clear directions for 

safely and efficiently handling the flow of traffic through or around the work zone.

A comprehensive MPT plan at a scale of 1” = 50’, including a written sequence of construction and special provisions, will be developed for all work areas for the entire

 project. Traffic control plans will consist of plan sheets detailing the staging at each end 

of the project where Turnpike traffic will be transitioned into and out of the work zone.

If the majority of the mainline reconstruction work will be done under the samecontinuous setup, a typical staging plan can be developed for each stage of mainline

work. Typical sections can be provided for those areas that deviate from the typical

staging plan. Typical sections can also be provided for structures where lane widths and work areas are restricted. The MPT plans will be an Also Plan set to the contract

documents.

Additional sources of information to supplement these design guidelines and the

Commission’s MPT Standard Drawings (PTS 900 Series) are contained in, but not

limited to, the PennDOT Publication 14M, Design Manual Part 3, Highway Plans

Presentation, Chapter 4; PennDOT Publication 212, Official Traffic Control Devices;PennDOT Publication 213, Work Zone Traffic Control Guidelines; PennDOT Publication

236M, Handbook of Approved Signs; the Manual on Uniform Traffic Control Devices

(MUTCD); and applicable PennDOT Traffic Standards from the various TCs.

Detail drawings will be prepared for every stage/phase of work showing all traffic control

signs except those signs shown on the Commission’s MPT Standard Drawings (PTS-900Series), and devices, temporary concrete barriers, temporary pavement markings, etc.

Where applicable, the PTS 900 series will be utilized in lieu of detailed drawings and/or 

referenced on the drawings.

4.1 General Notes 

Review PennDOT’s Work Zone Safety and Mobility Policy (WZSM) found in PennDOTPublication 46, Traffic Engineering Manual, and apply as necessary to the project.

Discuss results and recommendations with the Commission’s Traffic Department.

Long term traffic control operations will include maintenance of 12-foot wide travellanes. The number of lanes shall be consistent with existing lanes available and only be

reduced if authorized by the Commission’s Traffic Department.

Mainline turnpike traffic traveling in the same direction must be maintained on two

adjacent lanes for two lane sections or three adjacent lanes for three lane sections and can

not be split.

Oct 2011

Typical MPT staging for the mainline total reconstruction projects is to include anadditional run of temporary concrete barrier in the main reconstruction stages. The

additional run of temporary concrete barrier is to eliminate continuous single lane

 patterns for the movement of temporary concrete barrier between the main reconstructionstages.

A 1 foot or 2 foot (preferred) median in each direction is desirable during construction

staging when traffic in one or both directions is restricted between concrete barrier duringconstruction.

Use the following format and statements in the General Notes sections for Maintenanceand Protection of Traffic (MPT) on the first sheet of the MPT drawings, if applicable.

Add additional notes as necessary for site specific conditions.

Also, identify problem areas so that there are no surprises at the final plan

submission. If problems or questions arise after approval of the TS&L Plan, theseissues should be brought to the immediate attention of the Commission.

Quality Assurance (QA) Forms (per Design Manual Part 4, PP 1.9.3.3.1(f)) areonly required for structures that will be transferred to PennDOT ownership

Design runs (input and output files) from PennDOT computer programs may be provided electronically on DVD or compact disc; however, hard copy of full input

echoes and rating summaries are to be included in the submission. Jackets for all

discs are to be bound in the report (no loose discs).

The TS&L Plan for retaining walls, culverts and other buried structures will not

 be approved until a foundation recommendation and report is submitted.

For structures over waterways or carrying waterways, the TS&L Plan will not be

approved until a Hydrologic and Hydraulic Report has been submitted and 

approved.

B. TS&L Plans

In addition to the requirements of PennDOT DM-4, the following information is

to be the minimum shown on all TS&L drawings submitted to the Commission.

The scale for the plan and elevation will be no less than 1" = 30'. The submission

may consist of more than one drawing. A Key Plan is to be provided if theGeneral Plan and Elevation does not fit on one sheet.

specify deck surface treatments (i.e., boiled linseed oil) for exposed deck surface.

8. Provide a 4-inch nominal diameter multi-cell galvanized steel conduit with

factory installed inner-ducts (four (4) inner-ducts each having an insidediameter that matches the inside diameter of the 1-1/4” HDPE conduit) below

deck in accordance with PTC ITS Standard Drawings (PTS-355), and no

conduit in the parapets. The exception to this will be bridges at interchanges,

where a 2” conduit in the outside parapets is to be provided for potentiallighting or other electrical needs .

5.3 Overhead Structures (Carrying Facilities Over Mainline)

A. Approach Slabs

1. For structures carrying state routes, follow PennDOT guidelines to determine

if an approach slab is warranted and verify with the PennDOT District Office

to see if the approach slab is desired. Do not provide approach slabs for  bridges carrying Township roadways, unless approved by the PTC Bridge

Engineering Manager.

2. Do not depress the approach slab unless directed by the PTC BridgeEngineering Manager.

Oct 2011

B. Substructure

1.  Typically, provide a 14-foot shoulder from the edge of Turnpike travel lane tothe face of the abutment for full height abutments and 12-foot shoulder from

the edge of Turnpike travel to the curb for stub or semi-height abutments.

(Early coordination with the PennDOT District office on offset measurementis required) Provide abutment transition pieces in accordance with PTS-145

for full height abutments or place single-face barriers in front of the full height

abutments as directed by the PTC.

2.  Provide slope protection between the abutment and the mainline shoulder for stub and partial-height abutments. Use articulating cellular concrete block for 

all overhead structures with a concrete curb at the edge of the shoulder.

3.  Provide an architectural surface treatment on all overhead bridges, unlessdirected otherwise by the PTC. This treatment should be consistent throughout

the project corridor. Treatment on the pier should only extend down to the top

of the median barrier. If a reconstruction job changes the mainline Turnpike

 profile consideration should be given to treatment at the top of barrier.Portion of the pier from top of barrier to grade should be exposed concrete.

 No Anti-Graffiti coating to be applied.

4.  Do not provide bearing pedestals on the substructure units. Step or slope bridge seat from bearing area to bearing area.

5.  Provide 6” cheek wall at end of pier caps to hide bearings.

6.  For piers within the 10' existing median (interim condition), provide aminimum of 3'-6" clear from the edge of the lane to the face of the pier.

7.  For piers within the 10' existing median (interim condition), do not permit pier 

cap to extend more than two inches beyond the face of the stem when the pier cap is within the 16'-0" vertical clearance envelope.

8.  For piers within the 10' existing median (interim condition), transition CMB

to the faces of the pier and extend SFB the length of the pier on each side.9.  For median piers (final condition), transition Concrete Glare Screen to both

ends of the pier with a pier transition piece, PTS-147.

C. Superstructure

1.  Provide a minimum vertical clearance of 16'-0" over all travel lanes, shoulders

and traversable areas. Exemptions may be given by the PTC for specificsituations where this clearance cannot realistically be achieved over all points.

At a minimum, 16'-0" vertical clearance must be achieved over one lane in

each direction of traffic.2.  Do not use weathering steel for structures over the mainline.

3.  Adjacent box beam superstructures will not be allowed on any overhead 

 bridges because of the longer construction time to set beams.

4.  Future redecking schemes (staged or detour) should be considered for  beam/girder arrangements. Use beam spacing of 8'-6" (maximum) where

 possible.

Oct 2011

5.  Provide protective fencing for full length of structure on both exterior barriers

for all structures except on interchange ramp bridges. Anti-climb shields will

not be used on PTC owned Bridges. Verify with the PennDOT DistrictOffice if Anti-climb shields are warranted. Do not extend fencing onto wing

walls, unless directed.

6. 

Use precast structure-mounted median barrier if a median barrier is required on PTC structures.

D. Early Action Bridge Contracts

1.  Two (2) General Plan and Elevation sheets should be prepared. The first will

not show the future mainline lanes. The second should show the future

mainline lanes and clearly state that the sheet is only provided to depicthorizontal and vertical clearances for alternate bids.

Note: The ownership of overhead structures carrying state routes

(S.R’s) over the mainline will be transferred to PennDOTupon replacement. Therefore, coordination with the appropriate

PennDOT district throughout the design process is required.

5.4  General Structure Guidelines

A. Substructure

1.  Stub or mid-height abutments are preferred. Full height abutments may be

used if required to attain minimum vertical clearance or to accommodate other site restrictions.

2.  Integral abutments may be considered where favorable geological conditions

exist and the necessary bridge geometry requirements can be met. Complywith the requirements in PennDOT DM4, Appendix G, and standard drawings

BD-667M. Constructability should be considered in accommodating

construction staging, future widening and future redecking, when applicable.

3.  Using 11/2:1 slopes in front of stub or mid-height abutments, in conjunctionwith articulating cellular concrete block slope protection, is permissible to

minimize span lengths.

4.  Use same wing wall type and orientation for all wings on a particular structure. Unless there is a significant cost savings or site needs to utilize

different types. Differing wing wall types are subject to the approval of the

PTC Bridge Engineering Manager.5.  Design the height of flared wingwalls to provide a 12" clear dimension

 between the top of the wing wall and finished grade on the back of the wing

wall.

6.  Provide either flowable backfill or geogrid reinforced backfill for mainline bridges and PTC owned overhead bridges. Use current PTC standard 

drawings for details and pay limits. Use backfill in accordance with

Page 66: pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 66/208

5-8

Oct 2011

PennDOT standard drawings for all overhead bridges to be owned by

PennDOT.

7.  For multi-span overhead bridges, use a wall type pier for all piers. Pierslocated within the median are restricted to a maximum wall width of 3'-0".

Provide a pier cap with a maximum width of 3'-4” on all piers. The pier cap is

to be a minimum height of 2'-0". The ends of all pier walls and caps are to berounded. Exceptions will only be made for special site conditions or where

 bridge vertical clearance is greater than 25 feet. In these special cases other 

 pier types (i.e. hammerhead, multi-column, etc.) can be considered with

approval of the PTC Bridge Engineering Manager.8.  Submit details and basic dimensions for the proposed pier type to the PTC

Bridge Engineering Manager for approval prior to starting the pier design and 

detailing. This information should be included as part of the TS&L and foundation submissions.

9.  Minimum concrete cover over the steel reinforcement on all substructure units

with architectural surface treatment will be measured to the point of maximum

relief of the formliner.10. Provide a two foot minimum to four-foot maximum flat bench in front of stub

and mid-height abutments for future maintenance and inspection needs.

11. The bottom of footing elevations near streams is to be determined using thecriteria in DM 4.

12. Consider Design Manual 4, Foundation Special Considerations.

13. For foundations in a river environment, spread footings on soil are onlyallowed with PTC approval.

14. For spread footings on soil, perform a minimum lab testing of one

classification series and one direct or triaxle shear for each footing. Perform aminimum of one consolidation test for saturated clay below each footing.

Perform a minimum of one corrosion series test for each structure.

15. For pile and drilled shaft foundations, provide applicable information listed inDM 4.

16. Prepare a Foundation Report for each structure. The report will be a

standalone document and not part of the Preliminary Geotechnical

Engineering Report as indicated in DM 4.17. 50 ksi steel H-piles may be designed for axial capacity using a steel yield 

stress of 50 ksi. Special consideration should be given to quality of the rock 

 bearing stratum and pile driving requirements to achieve the proper designload/refusal without damage to the pile. For overhead bridges carrying state-

owned roadways, generally use 36 ksi for pile designs. Verify the design

criteria with the PennDOT District.18. When calculating the bearing capacity of rock using q ultimate for an

equivalent soil mass, choose a resistance factor, 0.35-0.55, based on rock 

quality and expected performance. (Consider rock RQO [%] and RMR 

method for determining how the rock will be modeled for bearing resistancecomputations.)

19. When selecting a friction angle for soil, referencing Foundation Analysis and 

 Design by Joseph E. Bowles or older versions of Design Manual 4 is

acceptable.20. For replacement of existing structures on the same alignment, it may be

 beneficial, if feasible; to have one of the proposed structure borings taken

through the existing footing (to determine as-built BFE) and one boring takenoutside the existing foundation footprint (to determine a more accurate top of 

 bedrock profile). Existing footings keyed 2' to 3' into rock may yield overly

conservative proposed BFE’s if only taken through existing footings.

21. Follow DM 4, for locating the bottom of footings impacted by scour requirements.

22. Design substructure units with provisions for future jacking for bearing

replacement and/or bearing reset. The preference is to widen the beam seat,or provide a jacking shelf for shallow bearings, to accommodate the jacks.

23. Provide the notes and details for anchor bolt installation as shown on BD-

613M, sheet 14 of 15.

24. Concrete bearing pedestal walls used with precast concrete arches will belimited to 3’ in height.

B. Superstructure

1.  Eliminate deck joints as much as possible. Use concrete end diaphragms

instead of backwalls where calculations permit. For multi-span bridges, makesuperstructure continuous over the piers.

2.  When staged construction results in placing a deck slab on a portion of a

structure adjacent to a previously placed portion, the difference in deflectiondue to dead load must be less than three inches. Because of web layover,

curved and skewed structures require a suggested construction procedure.

3.  Minimize or eliminate entirely the number of scuppers on the bridge deck butdo not allow water to spread into the travel lane. Size and space roadway

inlets off the structure to collect all runoff. Place scuppers before tooth and 

modular expansion dams, if necessary.

4.  For beam rehabilitation designs, achieve an inventory rating factor of 1.0 or greater for the H-20, HS-25, ML-80 and TK-527 vehicles and an operating

rating factor of 1.0 or greater for the P-82 vehicle. This requirement may be

waived by the bridge engineering manager if it results in larger or additional beams. Use the PHL-93 vehicle for all new beam designs.

5.  In lieu of moment and shear diagrams for PTC owned structures, provide on

the contract plans unfactored shear and moment values at tenth points for continuous girders; or the maximum values and splice point values for simple

spans. Include the values as indicated in DM 4. Also include a table of 

reactions for dead load, superimposed dead load and positive and negative live

load plus impact without load factors applied.6.  Provide load ratings on the design plan for all new bridges in accordance with

PennDOT DM 4

Oct 2011

7.  Provide on the contract plans composite and non-composite section properties

at each resisting section.

8.  Properly detail the expansion slots in the sole plates of elastomeric bearings toaccount for the longitudinal movement due to end rotation of beams caused by

camber.

9. 

The use of stone slopes within 50’ of the abutment will be prohibited. Aminimum of 50’ of bituminous curbing will be placed at each quadrant to

allow grass slopes to stabilize.

C. Drainage

1. Place inlets beyond ends of approach slabs. Do not place within approach

slab. Provide curbing from the bridge parapet to the inlets. For long U-wings, place inlets at end of wingwalls.

2. Provide a minimum of 50' of bituminous or concrete curbing extending out

the front end of the wing wall or safety wing wall at all four corners of the

 bridge, unless there is an inlet, in which case the curbing is to terminate at theinlet.

D. Retaining Walls

1. Single-face barrier is required in front of all retaining walls located at the edge

of mainline shoulder. Place barrier directly against retaining wall with no gap between. In the alternatives analysis for retaining walls, several factors

should be considered. Engineering judgment should be applied and presented 

 by the designer to the PTC Project Manager. If an MSE wall is to be used,then provide a moment slab underneath the shoulder with an integral single

face barrier to accommodate any impact. If a post and plank wall is to be used,

then no moment slab is required. See the PTC Project Manager or BridgeEngineering Manager if further clarification is needed.

2. Provide architectural treatment on all retaining walls visible from mainline

and on other retaining walls at the direction of the PTC. This treatment

should be consistent throughout the project corridor.3. The design consultant should prepare a design that will be bid as an either/or 

item as follows:

Either:

Retaining Wall, EB-XXX – As Designed 

Or:

Retaining Wall, EB-XXX – Contractor Alternate

This either/or item will require a project specific specification.

5-11

Oct 2011

E. Sound Barriers

1.  Use steel posts for all sound barriers located at edge of mainline shoulder.2.  All steel posts are to be galvanized and then powder coated or painted.

3.  Single-face barrier is required in front of all sound barriers located at edge of 

mainline shoulder  (see Figure 5.7.1). Place barrier   directly against sound  barrier. The sound barrier should not be designed for impact.

4.  Provide architectural treatment to the sound barrier panels as per the direction

of the PTC. This treatment should be consistent throughout the project

corridor. The Turnpike side of the sound wall will utilize formliners and theresident side will be pressed.

5.  For Commission owned structures, a 20-foot high (including the barrier 

height) sound barrier may be constructed across the superstructure. If theheight of the barrier adjacent to the bridge cannot be maintained, the variation

must be approved by the PTC Project Manager.

6.  For Commission owned structures, the panel length shall not exceed 12 feet.

F. Soldier Pile/Post and Plank Walls (Non-Anchored)

1.  The preferred design method should be in accordance with DM-4 using theLRFD discrete method of design. Alternate methods may be considered if 

 project site conditions dictate, subject to approval by the PTC Bridge

Engineering Manager.2.  When deflection controls design of steel post, limit deflection to 1”.

3.  Caissons are to be designed (diameter and length) using COM 624P or similar 

 program.4.  Caissons are not to be reinforced.

5.  Wall friction angle (delta) is 0 degrees when calculating passive pressure.

6.  Multiple Ka values can be used to help reduce the active earth pressure.7.  An increased phi value can be used (reduced Ka) for rock.

G. Sign Structures

1. Use monopipe sign structures for all mainline sign structures in accordance

with PTC standard drawings. A test bore should be drilled at the foundation

location. Pay the foundations for these structures as individual items, i.e.Class 3 Excavation, Class A Cement Concrete, Reinforcement Bars,

Temporary Shoring, etc. Do not pay as incidental to the sign structure.

H. General

1.  Provide an anti-graffiti coating on all exposed concrete surfaces without

architectural surface treatment, except for the bridge deck surface, abutment

 backwalls and bearing seats. The colors will be provided by the Commissionon a case by case basis. Coated areas include abutments, wingwalls, piers, all

faces of the bridge parapet and the outside face of P/S concrete fascia beams.

Do not place coating on the top and inside surfaces of the bridge parapets for 

overhead structures carrying, state owned roadways. Boiled linseed oil will be applied to those areas, as well as across the deck.

2.  Bid items for alternate structure designs will generally be utilized for both

overhead and mainline structures. Only one alternate structure will be used,consisting of a different material type than the designed structure (i.e. if steel

is designed only P/S will be allowed as an alternate.)

3.  Provide separate pay item, with special provision, for jacking of the

superstructure after deck placement in order to relieve stresses in elastomeric pads.

4.  For highly skewed structures investigate improving the skew to 70° or greater 

to improve performance. The ability to improve the skew is likely moreattainable on mainline structures than for overheads which may be governed 

 by the alignment of the median pier.

5.  Detail highway lighting components to eliminate the need for structuremounted poles. Any proposed structure mounted lighting must be approved by

the Bridge Engineering Manager.

6.  For curbed and skewed structures indicate if the structure is to be plumb aterecting or plumb under the full dead load existing at the end of construction,

which is preferred. Provide on the contract plans the anticipated differential

lateral deflection and resulting lateral rotation. For staged construction provide a suggested procedure for connecting diaphragms and constructing

the deck slab. Do not use concrete end diaphragms for these structures.

I. Software

1. For abutment, wall, pier, and culvert design and analysis on structures where

ownership will be transferred to PennDOT, use the current ABLRFD,PAPIER, and/or BXLRFD programs. For vertical pile lateral resistance, use

COM 624P computer program (Wang & Reese, 1993).

2. For PTC owned structures, other design/analysis programs are acceptable,contingent on approval by the PTC Bridge Engineering Manager (i.e.,

GStab17, LPile, FBPier, etc.).

Chapter 6 – RIGHT-OF-WAY

6.0 Introduction 

There are numerous factors that contribute to affecting private property that occur within

a design project. This chapter presents the guidelines required to prepare the associated  plans depicting these affected properties. All plans are to be prepared in accordance with

PennDOT Publication 14M, Design Manual Part 3 – Highway Plans Presentations,

PennDOT Publication 16M, Design Manual Part 5, Utility Relocation, and as directed bythe Commission.

6.1  Reestablishing Turnpike Right-of-Way Baselines – ‘Best-Fit’

A.  History

•  The “Original” part of the Pennsylvania Turnpike was built utilizing portions

of the old Southern Pennsylvania Railroad and Mining Company (South Penn)right-of-way from Irwin, Pennsylvania (Turnpike milepost 67) to Carlisle, PA

(Turnpike milepost 226). Through most of this section of Turnpike no

 permanent baseline reference monuments were set. Baselines were staked inthe field, and the only references set were hubs and tacks or nails/tacks in

trees, all long gone. The only exception to this was the construction of 

massive eight-foot (8’) square-topped stone pillar tower monuments (sometwelve feet high) the South Penn Railroad built at the breaks in grade over the

tunnels, upon which surveyors could set-up their instruments. With no

 permanent monuments being set to perpetuate the location of most of theTurnpike’s Centerline, the highway itself (the original 24-foot wide concrete

cart ways underneath the bituminous pavement, the bridges, storm water structures, and the concrete median barrier occupying the middle of the ten-foot (10’) wide medial strip) is the monument. The Right-of-Way Centerline

utilized “simple” curve geometry. The “Construction Centerline” in spiraled 

high degree-of-curve areas was offset (throw “p” distance) and was spiraled 

utilizing a peculiar “approximation” of a spiraled curve (not a realmathematical spiral) unique to the Pennsylvania Turnpike. As

reestablishment of the Right-of-Way Centerline requires the physical location

of the Construction Centerline’s monument (the highway) and then applyingthe offset distances between the two centerlines, a copy of the “Standard 

Turnpike Spiraling Method” can be obtained from the Turnpike Project

Manager, and should be utilized for spiraled curves between mileposts 67 and 226. Generally, the precision ratio for “Original Turnpike” surveys was

 between 1:1500 and 1:2000. The methodology for reestablishing a “best-fit”

of the Right-of-Way Centerline is presented below under “Original Turnpike – 

Best Fit”.

•  After completion of the Original Turnpike, the “Philadelphia Extension”(Carlisle to Valley Forge, milepost 226 to milepost 326), the “Western

Extension” (Ohio State Line to Irwin, milepost 0 to milepost 67), the“Delaware River Extension” (Valley Forge to the New Jersey State Line,

milepost 326 to 359), and finally, the “Northeast Extension” (Norristown toClarks Summit, milepost A-20.0 through A-131) were constructed. ThePhiladelphia, Western, and Delaware River Extensions had a few sections

 built without centerline reference monuments being set (and are to be treated 

for the purpose of reestablishing the “best-fit” Right-of-Way Centerline as“Original Turnpike”), but for the Turnpike sections properly monumented, the

methodology for reestablishment should be in accordance the procedures

 below under “Turnpike Extensions – Best-Fit”. The Northeast Extension was

fully-monumented (re-bars approximately forty inches (40”) long, some set inconcrete), with their surveys having precision ratios of 1:4000. Generally, the

 precision ratio for the Philadelphia, and Western Extensions surveys was

1:2500. The Delaware River Extension’s surveys precision ratio averaged 1:3500. Reestablishment of the Right-of-Way Centerline will require

adjustments be made to accommodate technological advances in surveying

 precision.

1.  Original Section And Turnpike Extensions – Best Fit

 

- Because most of 

the Original Turnpike had no Centerline reference monuments set, these

 procedures are to be followed. In addition, on Turnpike Extensionswithout reference monuments, utilize Original Turnpike procedures:

i.  On Original Sections of the Turnpike, the structures’ centerline by

centerline points (established from substructure working points) and location of the highway (the highway being the “monument”) shall

 be utilized to precisely “set” the reestablished location of the originalright-of-way baseline. The “best-fit” centerline will be an

adjustment (modern precise surveying techniques) applied for 

technological measuring advances. On Turnpike Extensions, theoriginal Right-of-Way baseline reference monuments (recovered and 

 positioned on the project datum) are based on the structures

centerline to centerline points (established from the substructure

working points).

ii.  The centerline geometry shown on the 1990 mosaics will bestored as a figure in COGO as the Right-of-Way Centerline

 No. 1. The coordinate geometry shown on the original

construction “as-built” plans will be stored as a figure inCOGO as the Right-of-Way Centerline No. 2. The two right-

of-way centerlines shall be rotated, translated, and compared 

to one another for “fit”.

Oct 201

Right-of-Way Centerlines 1 and 2 should match. Any discrepancies

 between the two shall be reported to the Commission Project

Manager for referral to and resolution by Commission Right-of-Waystaff. The resulting resolution shall be called the “Right-of-Way

Centerline”. It is understood that the Right-of-Way Centerline is in

simple curve format (which may be either arc or chord definition, possibly both, if two or more construction sections span this project);

 please verify.

ON the Northeast Extension ONLY, there are a few places where theLegal Right-of-Way Lines For Limited Access are “concentric with

and offset from” spiraled baselines. This is a “special” circumstance

and Commission right-of-way staff is to be consulted for “special” procedures to deal with these lines.

iii.  The aerial photography centerline (the centerline of the median

 barrier) will be supplied to Consultant in an ASCII coordinate file provided by the Commission. Curves derived from this file will reflect

as-built spiral curves. This file will be stored in COGO and a figure

derived by the “best-fit” command through tangents to establish PI’s.

iv.  The Right-of-Way Centerline figure will be superimposed in COGO

upon the aerial photography centerline (ASCII file), tied at one end tothe ASCII file figure and rotated onto the ASCII file figure. The Right-

of-Way Centerline will be slid incrementally in COGO along the

ASCII file figure and through the referenced centerline points(established from structure centerline by centerline points, median

 barrier ties, where available on the Original Sections; and established 

from recovered original monuments and structure centerline bycenterline points on the Turnpike Extensions, where available.) until

the two centerlines match each other as closely as possible. When

comparing the Right-of-Way Centerline to the aerial photography

centerline, the simple curve to spiral association (utilizing the uniqueStandard Turnpike Spiraling Method) where applicable on the Original

Turnpike Sections) shall be considered. The objective is to hold as

much of the right-of-way geometry as possible, especially along thetangents, and to adjust the curves as required, generally holding the

radius, and applying the spiraled curves.

v.  As a check for best-fit, offset distances will be computed between the

two lines by stations and offsets at 50-foot intervals. It is understood that differences of one (1) foot or less will generally be acceptable.

Areas of incongruity between the two centerlines that require the

introduction of any new PI’s will be reviewed with the Commission’sstaff prior to finalizing the best-fit centerline. The station and offset

comparisons and referenced field centerline tie comparisons will be

submitted to the Commission with a brief report on methodology,

 problems encountered, and resulting procedures used to achieve the best-fit centerline. The Commission will review and approve the best-

fit line.

vi.  The best-fit as-built centerline will become the basis for the re-

establishment of the existing Right-of-Way of the Turnpike for this

section of roadway. The existing right-of-way lines will be re-

established by using the breakpoints from the Right-of-Way mosaics(verified by deed) at the appropriate stations and offsets and tying

them to the best-fit centerline. The addition of station equations (best

fit as-built centerline) will be required to accomplish this tocompensate for the systematic errors created by earlier surveying

technology inadequacies, resulting in precision ratios of only 1:3000

(or less) on some original surveys. The right-of-way corners / right-of-way shift points between these station equation points on the best

fit as-built centerline shall have their positions’ stationing prorated to

adjust for the discrepancies created by the systematic early surveyingerrors. The corners’ offset distances from the baseline shall NOT be

 prorated; they are to be HELD. Simple curve format will be used for 

the establishment of right-of-way geometry. As a check,reestablished right-of-way lines and breakpoints will be compared 

with existing right-of-way fence breakpoints and field-located 

 property corners added to the mapping on the aerial photography

wherever possible.

vii.  At the limits of the project, the best-fit as-built centerline will be tied 

to the nearest PI (located by field survey) outside the project’s actuallimits of work in order to facilitate geometric conformity in

matching adjacent projects.

viii.  Station and offset ties between the approved best-fit as-built

centerline and the project’s new Right-of-Way - Construction

Baseline line will be shown on the final Right-of-Way / Geometry

Plans in no less than two places on each sheet (both edges).

ix.  Prior to beginning the work necessary to establish the best-fit as-

 built centerline, a meeting to review the above procedures will be

held with the Commission’s Right-of-Way staff.

6.2 Plan Requirements

A. Right-of-way – Mainline Only

The right-of-way plan set will consist of a title sheet Right-of-way/GeometryPlans and property plots for properties requiring perpetual easements and/or fee

simple acquisitions.

Mainline Right-of-way property plots will have Survey and Right-of-way

Baseline for the side road and a Survey and Right-of-way Baseline (which is the

 proposed baseline) for the Turnpike mainline. Right-of-way acquisitions that

affect the side road right-of-way will be referenced off the Survey and Right-of-way Baseline for the side road. Right-of-way acquisitions that affect the Turnpike

mainline right-of-way will be referenced off the Survey and Right-of-way

Baseline (which is the proposed baseline) for the Turnpike. All references(plusses and offsets) are to be shown on the plan as measured perpendicular or 

radial to the baseline from which they are referenced.

 No separate plot will be prepared for properties requiring only Temporary

Construction Easements (TCE). These TCE impacts will be shown on the

Roadway Plans, which are to be submitted in conjunction with the plots as part of the Construction Plan set. Stations, offsets, and areas for TCE’s will be

referenced to the Survey and Construction Baseline and labeled on said Roadway

Plans. Metes and bounds are not required to be shown for TCE’s. The standard TCE note should be included on said Roadway Plan.

All perpetual easements and fee simple acquisitions will show only the lines

 plotted and labeled accordingly.

B.  Right-of-way – Early Action Bridges, Side Roads, Access Ramps accepting/

discharging traffic onto any public roads:

For Early Action Side Roads requiring right-of-way acquisitions, side-road 

relocations, and access ramps discharging/accepting traffic onto/off public roads,a complete set of right-of-way plans are to be prepared in accordance with the

manuals listed above. The R/W plan set should mimic what is being

 built/acquired for that job. Applicable Right-of-way/Geometry Plans should be

included in the right-of-way plan set.

6-6

Oct 2011

Early Action Right-of-way plans will have Survey and Right-of-way Baseline for 

the side road and the Original Right-of-way Baseline for the Turnpike. Right-of-

way acquisitions that affect the side road right-of-way will be referenced off theSurvey and Right-of-way Baseline for the side road. Right-of-way acquisitions

that affect the Turnpike mainline right-of-way will be referenced off the Original

Right-of-way Baseline for the Turnpike.

All references (plusses and offsets) are to be shown on the plan as measured 

 perpendicular or radial to the baseline from which they are referenced.

 No separate plot will be prepared for properties requiring only Temporary

Construction Easements (TCE), unless a TCE goes to condemnation or the PM

requires it. These TCE impacts will be shown on the Roadway Plans, which areto be submitted in conjunction with the plots as part of the Construction Plan set.

Stations, offsets, and areas for TCE’s will be referenced to the Survey and 

Construction Baseline and labeled on said Roadway Plans. Metes and bounds are

not required to be shown for TCE’s. The standard TCE note should be included on said Roadway Plan.

All perpetual easements and fee simple acquisitions will show only the lines plotted and labeled accordingly.

The information to be presented on the Title Sheet shall be in accordance with

Design Manual 3, Chapter 3, except as follows:1.  Maps.

a.  State Map with Pennsylvania Turnpike Commission Districts shown in the

upper right corner  b.  Location map with project shown in upper left corner with scale presented.

2.  The block for the PTC Chief Engineer to stamp on the R/W title sheet should 

 be removed since the Design Engineer is stamping it and the Chief Engineer 

already has a place to sign it.3.  The Contract Number for the R/W plan set should match the construction

contract number. Each Plot will have a separate WBS number that is different

than the construction contract number.4.  Stationing Limits. The Stationing Limits shall be shown. If a parcel is

affected by both the Early Action Project and a Mainline Project, a plot shall

 be prepared identifying the required right-of-way for both projects.5.  Side Road Right-of-way Plan Sets. For the Turnpike, identify the

eastern/southern and western/northern most limits of right-of-way as:

D. Preparation of Property Plots Plans

1.  Legal metes and bounds descriptions shall be prepared for all fee simple and  perpetual easement acquisitions except properties which are “total takes”.

Total take acquisitions shall utilize the owner’s description, unless directed 

otherwise by the Commission. These descriptions are to be furnished by theConsultant in electronic (MS-Word) format for each parcel Where pluses

(stationing) numbers for corners are shown as “encircled” (scaled dimension)

on the right-of-way plans, the metes and bounds description shall identify thestation as “+/-“. Where the baseline offset distance numbers for corners are

shown as “encircled” (scaled dimension) on the right-of-way plans, the metes

and bounds description shall identify the offset distance as “more or less”. .

4.  Plot the entire “Deed of Record” property on one sheet. The deed calls (metes

and Bounds) shall be labeled on each property line, parallel to the applicable

line. Label this information as it is shown in the deed. When perches aregiven, also add the (feet) conversion in parenthesis. If clutter is a problem, a

full or partial tabulation should be used (preferred – use numbers inside

octagonal).5.  Consistent use of labels, text, charts and plan preparation (in general) shall be

maintained throughout the project.

E. Right-of-way/Geometry Plans

This work involves the preparation of final Right-of-way/Geometry Plans at a

scale of 1"=50'. The Right-of-way/Geometry Plan Sheets will show all ties between the Proposed Construction and Survey Baseline (to be labeled as Survey

and Right-of-way Baseline on these plans) and the original “best fit” alignment

that has been reestablished as the Original Right-of-way Baseline. Dual station

and offset baseline ties will be shown to all break points in the right-of-way lines.Project grid coordinates will also be shown for these points. These stations and 

offsets will denote station and offset data from the Original Right-of-way

Baseline in  slanted text and stations and offsets in bold vertical text from theSurvey and Right-of-way Baseline for each tie point with appropriate notations

and legends. Centerline geometry data will be provided for both the Original

Right-of-way and Survey and Right-of-way Baselines.

It is the consultant’s responsibility to obtain all recorded instruments to verify

supplemental right-of-way information provided by the Commission. In addition,copies of all records are to be forwarded to the Commission and/or the Design

Manager. Right-of-way/Geometry Plans will show and label all side road names

and route numbers, watercourse names and flow arrows, structure numbers, baseline stationing and station equalities, planimetric features, owner names,

 project parcel numbers, old and new right-of-way numbers, north arrow, labeled 

topography, and right-of-way dimensions. All coordinate notes, project grid 

coordinate conversion notes, centerline mileposts, and horizontal and verticalcontrol monuments will be shown on each plan.

All primary control will be depicted with elevations, coordinate values, and typeof control point established, i.e., bronze disc in concrete. Primary vertical control

 benchmarks will be shown with elevations in NAVD88 and coordinates in project

grid. Primary horizontal control monuments will be shown with coordinates in both project grid and NAD83 SPC with (applicable Zone) values with notation on

 both datum. Stations and offsets will be provided to all primary horizontal and 

vertical control monuments referenced to the Survey and Right-of-way Baseline

and the Original Right-of-way Baseline.

Oct 201

Baselines with bearings will be noted on each plan as the Survey and Right-of-

way Baseline and the Original Right-of-way Baseline. The Legal Right-of-Way

Line for Limited Access will be shown, labeled and noted with right-of-waynumbers. The plans will be prepared in accordance with Commission

requirements including the above stated information.

These Right-of-way/Geometry Plans will indicate/label those corners of the Legal

Right-of-Way line for Limited Access, which are to be monumented during

construction. Commission staff will review the plans at the pre-PS&E submission

and will specify which corners are to be monumented. These plans will beincorporated into the final Construction Plans.

It is not necessary to show plusses and offsets to the Legal Right-of-Way Line onthe construction plans if the right-of-way/geometry plans are included as part of 

the Contract Documents.

F. 

Required Right-of-Way Lines

Required Right-of-Way is to be taken in chords (creating straight right-of-way

lines and not curves). If a circumstance requires that a take creates a concentric-to-baseline or curved right-of-way line, approval by the Total Reconstruction

Program Manager must be obtained. Avoid (if possible) creating ANY new right-

of-way corners/shifts in right-of-way on existing property lines separatingadjacent owners. It is far more desirable to create new right-of-way corners away

from existing property lines by station (plus)/offset distance from a Commission

 baseline. If it is necessary to create a new corner/shift in right-of-way on anexisting property line between adjoining owners retracing and reestablishing that

 boundary line will be required.

If a property line coincides with the legal right-of-way line, the property line

symbol shall be shown on the right-of-way line on deed plots and Right-of-Way

 plans. However, on Construction/Roadway plans or Right-of-Way/Geometry

 plans do not show the property line symbol.

6.3 Right-of-way Summary Chart 

The Commission will supply the chart template which is to be prepared and updated by

the consultant and submitted with each right-of-way submission. Commission staff will be responsible for assigning right-of-way numbers for all impacted properties.

6.4 Utility Easements

A.  The property plot plan and the construction plan shall show all utility

easements. If a utility crosses the Turnpike right-of-way and the utility has an

existing private easement connecting to the legal limited access right-of-wayline, the private easement will remain for any portion of the easement

 bounded by the old and new right-of-way lines. A note shall also be included 

that indicates the name of the utility involved with the easement. See Figure

6.4.1.

B.  When it is necessary to acquire substitute right-of-way for a utility, the

designer shall obtain a copy of the utility’s existing right-of-way documentsfor the right-of-way overtaken by the highway. Also, a copy of the utility’s

current right-of-way agreement form shall be obtained. Prior to obtaining the

right-of-way, a meeting with the utility shall be held to discuss the private

rights. The legal description for the replacement right-of-way shall providethe replacement of the utility’s existing private rights. The utility shall

approve of the legal description before it is finalized. When the right-of-way

acquisition is complete, a copy of the legal description shall be provided to theutility. Refer to Design Manual Part 5, Section 6.3, Utility Relocation for 

more details on the acquisition of substitute right-of-way.

Chapter 7 – Drainage, Stormwater Management Design, and Erosion and Sediment

Pollution Control Plans

7.0 Introduction

While this chapter is divided into separate sections for Drainage and Stormwater Management,the designer must approach the layout of the roadway drainage system from a stormwater 

management perspective. As the Regulatory Agencies, Counties and Townships become more

sophisticated in their approach to the regulation of stormwater discharges (i.e., the PostConstruction Stormwater Management section of the NPDES permit), the use of sound

stormwater management practices must be applied during the development of drainage designs.

Oct 2011

2.  Compliance

  Federal Emergency Management Agency (FEMA) flood maps will determine if 

the proposed activity encroaches on a regulatory floodway.  A water obstruction or encroachment with a drainage area more than 100 acres

requires a joint (DEP and US Army Corps of Engineers) or general permit (DEP)

application, whichever is applicable.

  Provide supporting hydrologic and hydraulic computations as required by DEP’sGeneral Permit for wetland disturbance areas of less than 0.1 acre. However, for 

wetland disturbance areas of 0.1 acre or more, DEP’s Joint Application with

supporting documentation is required.

  Any stormwater management detention basin with an embankment 15 feet or greater in height, or with contributing drainage area exceeding 100 acres, or with

impounding capacity at maximum storage elevation exceeding 50 acre-feet

requires a DEP Dam Permit and should be avoided where possible.

3.  Drainage Systems

  All drainage facilities less than 10 feet in depth from the existing or proposedfinished grade to the top of the pipe will be replaced.

  Drainage facilities greater than 10 feet in depth from the existing or proposedfinished grade to the top of pipe will be inspected and the results included in a

“Deep Culvert Inspection Report.” The designer will physically inspect pipesgreater than 36-inches in diameter. Pipes less than or equal to 36-inches in

diameter will be video logged by the designer and a copy of the tape provided to

the Commission as part of a “Deep Culvert Inspection Report”. The “DeepCulvert Inspection Report” should indicate whether the drainage system is

recommended for rehabilitation, reconstruction, or extension.

  In developing the new drainage system and the construction staging for the project, consideration will be given to placing the new drainage systemat the existing drainage location as much as possible to minimize boring.

  For shoulder and paved median inlets, use flowable backfill material.

B.  Storm Drainage

1.  Hydrology

a.  Runoff factors should follow Design Manual 2, Chapter 10, Table 10.2.1 or local governing storm ordinances if the ordinances are more stringent for the

design and approval by the necessary regulatory agencies.

 b.  Design storm frequency:

Page 85: pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 85/208

7-3

Oct 2011

For temporary conditions use 2-year storm.

2.  Storm Pipe

a.  The minimum diameter of cross pipes under the roadway that are deeper than 10feet shall be a minimum 24 inch.

 b.  A 0.5% minimum slope to be provided, with 1% being the desired minimum.

Maximum slope to be 10% unless a steep slope pipe design is provided.

c.  Combination storm sewer and underdrain is to be used for parallel storm sewersin cut conditions and in the median.

d.  Two pipe alternates will be used for all storm sewer pipes. In general,

reinforced concrete and thermoplastic will be used for most conditions and

coated polymer corrugated galvanized steel pipe or thermoplastic pipe will beused for slope pipe. The design will be based on the highest “n” factor for the

alternatives. The pipe outlet design will be based on the lowest “n” factor for the alternates.

  Reinforced concrete pipe will be Type A with an approximate 100-year expected service life. “PAIDD” must be used for all concrete pipes with fill

heights greater than 15 feet.

  Coated (polymer) corrugated galvanized steel pipe will be Type I with2-2/3" x 1/2 " corrugations and designed with an approximate 50-year 

expected service life.

  For thermoplastic pipe;Slopes: Group V

All Other Areas: Group VIe.  Designers should consider the available sizes of pipes when developing

drainage systems and verify that pipe sizes being specified are available asalternatives.

3.  Inlets

a.  Locations

  Minimum spacing of inlets is to be 100 feet except in sag conditions.Bypass flow will be permitted to achieve economical spacing as long as

depth and spread criteria are maintained  Inlets in depressed or unpaved median sections are to be placed so the width

of water flowing in the median does not exceed 2/3 the total median width,

for medians greater than or equal to 22’ width. For medians less than 22’,see the project manager for requirements. Additional inlets beyond the

minimum spacing criteria may be needed to achieve the 2/3 spread in

certain instances, such as full superelevation or flat grade.

  Provide inlets in the shoulders and median on the low side of mainline bridges. Provide inlets in the median on the high side. Inlets in the right

shoulder are to be placed at the ends of the approach slabs with curbing

extending from the wing wall or safety wall to the inlet.  Provide inlets in the shoulder on the low side of overhead bridges. Locate

the inlets at the ends of the approach slabs if present and provide curbing

extending from the wing wall or safety wing to the inlet.

  Outletting of median inlets into shoulder inlets and slope pipes is preferred.

  Depress inlets in median and shoulder areas one inch below the normal flow

line, unless temporary traffic is anticipated over the inlets.

 b.  Types

  Use Type C Inlets on shoulders which have approach slabs and concrete

curbs.  Use Type M Inlets with frames in paved medians requiring drainage on only

one (1) side of a concrete median barrier and on shoulders adjacent to

single-face barrier.

  Use Type M Double Inlets with concrete top units in paved mediansrequiring drainage on both sides of a concrete median barrier.

  Use Type M Inlets with concrete top units in fill shoulders and unpavedmedians.

  Use Type S Inlets in swales and on shoulders with rollup curbs and swaleconditions.

  Type D-H inlets may be used to accommodate high storm runoff but may

only be used if approved by the project manager. PTC has not utilized thistype of inlet and it should only be used if approved by the project manager.

4.  Ditches/Swales

a.  The minimum ditch grade to be used is 1.0 percent.

 b.  The minimum ditch depth to be used is one (1) foot.c.  Design ditches and their locations in accordance with the following

a.  In general, shallow culverts, culverts less than 10 feet deep from the existingor proposed finished grade to the top of the culvert, will be replaced.

Hydrologic analysis for the 50-year storm frequency will be used to

determine flows. For culverts in excess of 100 feet in length, the 100-year 

storm shall be included in the hydraulic computations for flood risk evaluation.

 b.  Deep culverts, culverts greater than 10 feet deep will be addressed based on

the results of the “Deep Culvert Inspection Report”. Culverts that require

rehabilitation will be lined with an acceptable material and system.c.  Where horizontal elliptical pipe is needed because of a restrictive vertical

clearance, a concrete pipe will be used.d.  Culverts listed in the PTC bridge log should be inspected for replacement or rehabilitation and extension.

e.  discussion on the use of depressed culverts by agencies.

7. Endwalls and End Sections

a.  Inlet Conditions

  Concrete end sections shall be used.

  All pipes, 36 inches and greater, require a Type D-W endwall.

 b.  Outlet Conditions

  Concrete end sections shall be used to terminate pipes out letting ontraversable slopes (without guide rail) within the clear zone.

  If an end section is necessary, it should be concrete.

  All pipes, 36 inches and greater, require a Type D-W endwall.

8. Pavement Base Drain

a.  Use six-inch minimum pavement base drains.

 b.  Base drains will extend to the limits of the project along both inside andoutside edges of pavement in both tangent and superelevated sections of 

roadways and as follows:

ramps.

c.  Base drains will be outlet in accordance with the Commission Specification

Section 615.

d.  Outlet spacing for 300 feet desirable, 450 feet maximum. If this outlet

spacing cannot be obtained, the size of the base drain will be increased fromsix (6) inches to eight (8) inches at the Commission’s discretion. 

9. Rock Armor and Bituminous Curb

a.  Rock armor is to be in accordance with PTS-124 and should be utilized on

all fill slopes 2:1 or steeper in conjunction with guide rail to prevent

embankment erosion. b.  Rock armor should extend to the top of rock in rock embankments.

c.  Rock armor may also be utilized on fills with recurring erosion problems.

d.  Bituminous curbs should be used to prevent sheet flow drainage ontoretaining walls or geogrid reinforcement fill embankments.

7.2 STORMWATER MANAGEMENT

A. Stormwater Management Ordinances

Stormwater Management Ordinances should be met according to the regulationsas described below and in Section 7.2.B.1. A matrix comparing these

Ordinances should be prepared and submitted to the PTC PM. This matrix will

show the requirements and any discrepancies between a through c below, at

which point the Commission can make a decision on the criteria to follow. It is possible for a job to pass through multiple municipalities and Act 167’s. 

a.  Municipal Ordinance (City/Township/Borough) b.  Approved Act 167 Plan

c. 

PaDEP regulations

Oct 2011

B.  Act 167 Plans and Municipal Ordinances

The Commission must be consistent with the standards of watershed-based

stormwater management plans approved and implemented under the Stormwater Management Act (1978 Act 167); The Commission does, strive to maintain goodrelations with local municipalities and, at the Commission’s direction will comply

with local ordinances when feasible and practicable. It is the intent of the

Commission to submit the Post Construction Stormwater Management Plan

(PCSM Plan) to each municipality for their review. The Design Consultant willrequest a Stormwater and Floodplain Consistency letter from the municipality for 

inclusion in the Joint Permit Application and NPDES. If after significant

coordination, the local municipality will not provide the requested Consistency

letter, then the Design Consultant will submit to DEP appropriate correspondencedocumenting said coordination efforts in lieu of the Consistency Letter.

If there is no Act 167 plan or municipal ordinances, follow DEP regulations.

C.  Antidegradation and Post Construction Stormwater Management Plan

Requirements

Four key measures are used to assess the potential for impacts from stormwater 

runoff  – volume, rate, thermal impact and water quality. The goal of PCSM Plan

is to prevent or minimize any increase in the quantity (rate and volume) of runoff while also minimizing the factors affecting the water quality and thermal impact.

The best way to achieve antidegradation is to mimic the natural, pre-development

hydrologic conditions, which are usually dominated by infiltration andevapotranspiration. This is a two-fold solution because stormwater management

strategies that address quantity normally also address water quality and thermal

impact. Often the linear nature of highway projects could limit viable options for 

rate and volume reduction. Therefore, it is also important to have a combinationof strategies that reduce the amount of runoff being generated. Serious

consideration must be given to the property impacts that occur due to meeting the

requirements and it is possible that a balance between criteria and propertyimpacts must be evaluated. It is important that the Designer develop plans to a

sufficient level of detail that can be presented to the public, therefore it is

important to coordinate early with regulatory Agencies and municipalities. The

Commission does not want to present a stormwater plan to the public that willrequire significant changes in final design.

D. Post Construction Stormwater Management Plans

The County Conservation District and PaDEP may not review the PCSM Plan.

However, they will review the NPDES application for completeness and make surea post construction stormwater management plan has been prepared and is attached.The information for the table in Section E of the NPDES Application will need to be

completed.

A summary (peak flow control) shall be included in the PCSM Plan, includingsummary tables of hydrologic parameters and pre and post-development peak 

discharges. It is the intent of the Commission to manage stormwater per the criteria

where practical and feasible. If these criteria cannot be fully met, then all

appropriate documentation shall be included in the PCSM Plan for review andconcurrence by the County Conservation District and PaDEP.

A PCSM Plan must be included with the NPDES Permit submittal as a separatedocument and shall document all permanent stormwater BMP’s. It should not be

incorporated into the erosion and sediment pollution control plan and narrative.

However, the development of both plans should be closely coordinated.

For PCSM guidelines, refer to PaDEP’s Pennsylvania Stormwater Best

Management Practices Manual, Latest Edition. Submit a copy of the approved

PCSM Plan to the PTC Roadway Unit. It is the intent of the Commission to usesimilar BMP’s and materials for ease of maintenance and as such, the design of 

these facilities should be coordinated with the PTC Roadway Unit before they are

submitted to the Agencies for approval.

E. Post Construction Stormwater Management Plans For PTC Maintenance

A PCSM Plan will need to be provided for use by the PTC for maintenanceactivities. This Plan must be submitted with the 90% submission and is to be

reviewed by the PTC Roadway Unit. This plan should only contain information

necessary to allow for the proper maintenance of the SWM facilities. Thefollowing items shall be included in the plan set.

  Location/ Index Map  –  Plan sheet(s) showing the baseline and location of each BMP used with the milepost designation called and station shown on the

sheet.

  Plan Views  –  Plan sheet(s) showing plan views of each BMP. MultipleBMP’s can be shown on a sheet. This needs to be shown at a scale such that

all important information is easily readable.

  Details  –  Plan sheet(s) showing all details needed to properly maintain theBMP’s. This may not include all the design details, such as anti-seep collars,

Page 93: pa turnpike design consistancy manual 2011

that are not pertinent to maintenance. If a BMP has an access point off the

system, the location of the access needs to be shown on the plan.

  Written PCSM Plan  –  Plan sheet giving written maintenance instructions

including type of maintenance required and frequency. List the BMP andinstructions in general terms, if a BMP requires special maintenance list that

BMP and its location separately.

  The goal is to produce a concise set of plans that only pertains to maintenance.To that end, keep the number of sheets to a minimum.

F. NPDES Permit Submittal Procedures

A pre-application meeting will be held prior to the submittal of either the E&SPC

 plans or the NPDES Permit Application to the appropriate County Conservation

District (CCD) and\or the PaDEP Regional Office. The E&SPC Plans should then

 be revised based upon any comments the Agencies may have and be submitted promptly following the pre-application meeting.

The NPDES Permit Boundary needs to be clearly defined and include the entire

 project site. For a multiple phase and multiple year project, the NPDES Permit

Boundary, limit of disturbance, right-of-way and easement lines should be

coincidental. Use engineering judgment for all other projects.

The Design Consultant will be responsible for preparing and submitting the

application for the NPDES (Chapter 102 Earth Disturbance) Permit for the project.The NPDES Permit Package will consist of a complete NPDES Permit Application

and Checklist, a completed Conservation District Review Application, the GeneralInformation Form (GIF), Act 14, 67, 68, and 127 letters, PHMC approval letters, a

U.S.G.S Topographic Map Section 1" = 2000’ with coordinates showing thelocation of the project, and copies of up-to-date PNDI approval letters. In general

the Commission will be the applicant for and sign for the permits, and upon award

of the construction contract, the Contractor(s) will become Co-Permittees. PaDEPCo-Permittee forms will be prepared and sent to the PaDEP Regional Office once

the Contractor is selected. The Design Consultant will provide coordination with the

appropriate CCD and/or PaDEP Regional Offices for plan reviews and approvals.The specific requirements of Design-Build projects may vary.

A PCSM Plan must be included with the NPDES Permit submittal as a separatedocument and shall document all permanent stormwater BMP’s. It should not be

incorporated into the erosion and sediment pollution control plan and narrative.However, the development of both plans should be closely coordinated.

As part of the Chapter 102 Regulations which became effective on Nov. 19, 2010,

DEP is charging review fees for NPDES permit applications. The fee structure is

outlined in Section 102.6 and the Commission is required to submit those feeswith the application. Consultants should issue the checks and submit them as a

direct cost in an invoice.

Conservation Districts may charge additional fees according to the ConservationDistrict Law. The Commission is in the process of coordination with the PA

Association of Conservation Districts to establish a uniform fee structure withinthe counties through which the Turnpike traverses. Further information will be provided regarding this matter.

In some instances the Commission might reimburse the municipality for reasonable costs incurred up to a maximum dollar amount during the stormwater 

management review.

G. BMP’s 

The Commission intends to follow the PCSM Levels for Projects in Table 7.2.1

 below and the preferred order of BMP toolbox level listed in Table 7.2.2 below.It is important to remember that not all projects will have the ability to use the

following BMP’s in the preferred order listed  below in Table 7.2.2.

Circumstances that require BMP’s not listed to be considered should be justified

to and approved by the Commission prior to being utilized.

Site specific infiltration testing should be included for the design of infiltration

BMP’s. If site conditions prohibit infiltration (i.e. shallow bedrock, karstgeology, shallow groundwater, etc.), then specific recommendations from the

RSGER should be included to document these constraints.

Permanent Detention Basins

1.  See the following Figures 7.2.1 and 7.2.2 for general guidelines for permanentdetention basins.

2. 

If a basin requires fencing, use Type 1 Right-of-way Fence, per RC-60M, around the perimeter of the detention basin with a Vehicular Access Gate. Install the access gatewhere the access drive meets the fence. It should be noted that if a facility is in a

 populated area, the Commission would consider alternative fencing types.

3.  If a basin is within Commission right-of-way and Commission right-of-way is fenced,

then no fencing around the basin is required.4.  Provide the access drive to the detention basin at the end of the guide rail run beyond

the detention basin.

5.  Provide a minimum 10-foot-wide berm around the perimeter of the detention basin.

6.  Use 10-inch minimum depth of 2RC Aggregate around the top of the berm.7.  Use 10-inch minimum depth of 2RC aggregate for access drives with grades less then

6 percent. Pave the access drive with six (6) inches of subbase and four (4) inches of  binder for access drives with grades of 6 percent or greater.8.  The mainline shoulder should be 14 feet wide for a distance of 100 feet before and

after the access ramp. Use a 50-foot taper to widen the shoulder.

9.  Mosquito issues should be considered during the design of a basin.10. Design detention basins following review of the local stormwater ordinances and

with an aesthetic approach to the final look, particularly when the basin will be highly

visible.

11. Designers should attempt to avoid detention basins 15 feet and greater in depth, sincethis makes the basins jurisdictional dams as per DEP regulations, see Section 7.1.A.2.

12. Access drive desirable width is 15 feet and minimum width is 12 feet.

13. The desired radius off the mainline is 50’ and the minimum is 40’.14. Provide correct grading at the connection of the access drive to the mainline.

Maximum side slopes of 6:1 are required within the clear zone.

15. Provide guide rail as required by current design criteria.

16. Use sediment forebays for all Rain Gardens/Bio-Retention and Permanent Basins.17. Construction vehicles should not be permitted to traverse across the BMP area.

18. Any amended soil mix for a rain garden/bio-retention or any other BMP structure

should not be compacted. The placement of the soil should be made by hand or by ameans not to have any equipment on the amended soil during placement. This note

should be placed on all applicable plan sheets.

19. Use Plant List Figure 7.27 as a recommended guide all BMP’s requiring plant material.

Chapter 8 – GEOTECHNICAL DESIGN

8.0 Reconnaissance Plan

A.  Objective

This is a project specific task which, if scoped to be formally completed, is performed during Preliminary Engineering. The magnitude and scope of this task is sized to fit the

 project. Generally, Total Reconstructions and Expansion projects require a separate

Reconnaissance Plan deliverable. Smaller projects may combine the submission withthe Problem Statement Draft Exploration Plan (PSDEP) submission or others may

delete it entirely. However, on all projects, the consultant is responsible for a review

of available information and the performance of a site inspection.

A Reconnaissance Plan is required for all bridge projects to be turned back to PADOT.It should be submitted with the TS&L submission.

The Reconnaissance Plan is a presentation of available geotechnical information and 

observed site conditions. The purpose is to obtain an overall perspective of the site and 

identify geotechnical issues needing further investigation. The plan will also be used to provide a basis for future exploration needs. It is not intended to evaluate, in detail, the

quality of the soils and geologic materials, but to identify the favorable and 

objectionable geotechnical issues and features of the site.

B.  Scope

Reconnaissance Plan requirements:.

1.  Review available published and unpublished information including an evaluation of 

the following:

•  Preliminary plans of the proposed construction.

•  As-built plans of the existing roadway and/or structures (if, applicable).

•  Surface features on topographic maps.

•  Geologic maps and other sources of geologic information.

•  Soil survey maps.

•  Aerial photographs.

•  Previous geotechnical explorations in the vicinity of the project, including anystudies done during the environmental evaluation for the project.

•  Location of water supply wells and/or springs

•  Logs of existing borings and water wells

•  Records and photographs regarding the construction and behavior of nearby

structures relative to planned structures.

2.  Conduct a site inspection to verify information obtained by the publicationsearch, including the following:

•  Location of proposed construction.

•  Existing structures (type and condition).

•  Surface soils.

•  Topography and vegetation.

•  Drainage features.

•  Rock outcrops, excavations, and other visible indications of subsurfaceconditions. If possible, confirm geologic contacts and formations.

•  Existing problem areas, such as slope movements, subsidence, mineshafts, or sinkholes

•  Location of water supply wells and/or springs within 200 ft of future

geotechnical borings•  Utility locations.

3.  Prepare the Reconnaissance Plan

C.  Deliverable

Prepare a set of plans to present the obtained information. Provide the plan on a

topographic base map with cross sections and profile. Since the field 

reconnaissance typically occurs early in preliminary design, the development of  project plans, cross sections, and profiles may be limited. The use of CAD is

encouraged since it is easy to continually transfer the reconnaissance informationto updated project line and grade plans as they are developed. Prepare the plans ata scale appropriate for the project, with 1 inch equals 50 feet commonly used.

Submit half-size (11-inch x 17-inch) copies. Include the following:

•  Proposed construction (provide date of line and grade).

•  Data obtained during the search of published and unpublished information,

including inferred or actual geologic contacts, lithologies, bedding orientation

and structure.

•  Features and structures observed during the visual site inspection and, if appropriate, air photo interpretation.

•  Identification of soil units and geological formations in the area, including astratigraphic column identifying the geologic units encountered for the

 project.

•  Conditions and anticipated geotechnical issues to be encountered in thesubsurface.

Submit deliverable electronically in PDF format through the prime consultant.

• On larger projects or projects with significant geotechnical issues or geologichazards (i.e., slope stability, mining, karst, etc…) a presentation of the draft

reconnaissance plan (with a hard copy of the Draft Reconnaissance PlanDeliverable) shall occur with the project team at a special geotechnical meeting.

Parties to the discussion may include the PTC, General Engineering Consultant

(GEC), the Design Manager, the geotechnical consultant, and the designer.Collectively the geotechnical representatives of the PTC, GEC and the Design

Manager are referred to as the Geotechnical Design Management Team (GDMT).

A summary of the key findings of the final deliverable can be presented at a designstatus meeting.

8.1 Problem Statement Draft Exploration Plan (PSDEP)

A.  Objective

The PSDEP is the most project-tailored of the geotechnical submissions. For Turnpike bridge projects of one (1) to as many as three (3) spans, the PSDEP can, and should,

consist of only a boring plan and schedule of borings. However, for all bridges to be

turned back to PADOT and all bridge projects of four or more spans, a full PSDEPreport with appendices is required. Many projects are scoped such that the PSDEP is

submitted in combination with the Reconnaissance Plan.

The purpose of the PSDEP is to communicate problematic geotechnical issues, if any,for the proposed construction in conjunction with outlining the proposed boring and 

laboratory testing programs.

B.  Scope

The PSDEP requirements:

1.  Identify problem areas where more soil, rock and/or water information is needed.

2.  Propose a drilling program to address the needs of the identified problem areas.3.  Propose a laboratory testing program for soil, rock and/or water to address the

needs of the identified problem areas.

C.  Deliverable

Include the following: 

1.  Project description and identified problem issues and/or areas of concern. Provide

simple references to the information on the reconnaissance plan (if appropriate),

and a brief statement that presents the geotechnical issues identified at the project.

2.  Provide a summary of available information from previous sources including

 previous laboratory test results, if available. Presentation of data in tables is preferred, but not required.

3. 

Drilling program – Provide the following:

•  Attach a copy of the reconnaissance plan with the proposed boringlocation plan.

•  Provide a clear description of the borehole termination criteria. For structures, get a full subsurface geologic section where practical.

•  Include a summary table that identifies each boring, boring depths, depthsof soil to be sampled, depths of bedrock to be cored, applicable borehole

termination criteria, and costs.

•  Typical termination criteria may include:  Spread Footings: Two borings per substructure; one of which extends

2B (width) below the estimated bottom of footing and the other extends 10 ft into rock below the estimated bottom of footing.

  End-bearing piles: Two borings per substructure, 15 ft into rock below

the anticipated pile tip.

o  Drilled shafts: Two borings per substructure; one of which extends

five times the diameter of the shaft into rock and the other extends

10 ft into rock below the tip.

o  Friction piles: Determined prior to drilling based on a preliminary

friction pile length estimates.

o  Roadway Embankment: 5 ft into rock or suitable % of embankment height and upon reaching competent material.

o  Roadway Cuts: 10 ft of stratigraphic overlap with adjacent boringsor 10 ft below the proposed finish or subgrade elevation.

•  If drilling is by PTC open-end drilling contract, adapt the submission tocomply with the requirements of Section 8.2 PTC Open-End Contract

Drilling Guidelines and Procedures.

•  If the Consultant is administering a Subsurface Boring Sampling and Testing Contract (SBSTC), then a copy of the contract documents withspecial provisions should be provided with the PSDEP submission.

•  Identify whether Maintenance and Protection of Traffic (MPT) will berequired Include, if available, TS&L or other preliminary plans for 

structures to be drilled.

•  Drill final design structure borings prior to TS&L approval only with thePTC project manager’s and the Design Manager’s concurrence.

Significant structural changes may render the boring information useless.The need to maintain project schedule should be compared to the risk of 

having to re-drill the boring(s).

4.  Laboratory Testing Program – Include the following:

• Identify the AMRL certified lab that will perform the tests and provide a copyof their AMRL certification.

•  Provide a summary table identifying the type of test, the purpose for testing,number of samples, sample cost per test and total estimated cost. Include an

explanation as to why any special tests are requested. Consideration should be

made to use presumptive values instead of performing uniaxial compression

tests or point load tests of rock specimens. Provide hand drawn subsurfacecross sections to verify that significant soil, rock and/or water are being tested 

and identify the number of tests to verify that the significant soil, rock and/or 

water issues are adequately addressed. Generally, for projects with less than2000 LF of drilling, the Laboratory Testing Program submission is to be a

single request for the entire project. For projects with greater than 2000 LFdrilling, partial submissions of the proposed laboratory testing are permissible.The submission should include:

  Laboratory testing budget (from Scope of Work)  Previously approved testing and cost  Currently requested testing and cost

Generally, corrosivity and/or acid-base testing is conducted in Final Design, except for field pH measurements of surface waters.

5. 

Electronic file Submission

Submit electronically in PDF format through the prime consultant.

8.2 PTC Open-End Contract Drilling Guidelines and Procedures

A.  Objective

The following guidelines are to be followed for projects requiring PTC administered 

open-end contract drilling. They are not intended for Consultant or Design Manager 

administered open-end contracts.

PTC open-end drilling is performed on a work order basis. A work order consists of 

those borings which are approved for drilling, identified on a contract specific scheduleof borings, and are staked (survey optional) in the field. Individual bridge replacement

 projects are typically completed in one work order. Larger multiple bridge or total

reconstruction projects may require several work orders for each phase of design, e.g.,

roadway borings, structure borings, pavement borings.

B.  Scope

The PTC will:

1. Prepare and administrate the Subsurface Boring, Sampling and TestingContract for subsurface drilling.

2. Provide the Consultant with a copy of the applicable open-end drilling

contract documents along with a contract specific schedule of borings.3. Establish initial contacts between other PTC departments (e.g., Maintenance,

State Police, etc.) regarding the proposed drilling.

4. Coordinate the geotechnical subsurface drilling and sampling.

5. Review and process drilling invoices.

The Consultant will:

1. Stake or otherwise mark the boring locations using white flagging and/or

feet per day for karst areas.

color is required by the

PA one-call.

3. Submit a boring location plan and an open-end contract specific schedule of 

 borings. The schedule of borings should include the contract pay items proposed quantities and termination criteria. For out-of-scope items, the

consultant is responsible for providing a special provision. The PTC will

negotiate a unit price with the Drilling Contractor and notify the Consultant of the results.

4. Provide property owner information to driller for borings located outside the

Commission’s right-of-way.5. Attend a pre-drilling test boring field view meeting. This meeting is arranged 

 by the PTC to present the boring locations to the drilling contractor and to

discuss starting dates and workday schedules, boring access/property owner 

issues, possible utility interferences, MPT requirements, exchange cell phonenumbers, etc. The Consultant’s inspector in charge during drilling is required 

to attend this meeting and prepare meeting minutes.

6. Submit bulleted meeting minutes and, if needed, a revised plan and scheduleof borings within 2 days of the test boring field view meeting. These are

needed in order for the PTC to issue a notice to proceed to the drilling

contractor.7. Provide full-time inspection of the boring operations and complete field logs

and PTC daily reports. The lead inspector is required to carry a cell phone

during drilling operations.8. Provide a daily quantities summary of drilling contract pay items weekly

8.3 Geotechnical Engineering Report (GER) Submission Guidelines

The distinction between a roadway project with a bridge and bridge project with roadway work is up to the project team with the Commission’s approval. In general, when the approach

roadway work limit is within 500 feet from the bridge, the cut/fills are less than 10 feet, and 

unusual conditions are not anticipated, the project can be considered a bridge project and a

roadway GER is not required.

A.  Objective

The GER is intended to present recommendations addressing the subsurface conditions

identified in investigations which will impact the design and construction of the

roadway and its associated structures.

B.  Scope of Work 

The process from collection of field data to GER approval can be expedited through theuse of three major steps:

1.  Collection and Submission of Data to be Used for Geotechnical Design(Geotechnical Data Submission)

Page 113: pa turnpike design consistancy manual 2011

7/14/2019 pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 113/208

8-8

Oct 2011

Upon completion of the boring and testing programs, submit draft versions of the as-drilled boring location plan, typed engineer’s boring logs, and relevant

 boring profiles. Submit a summary of soil, rock and water testing performed,along with the raw test data. Reference the date of the boring and testing program approval, and note any major discrepancies. Also submit other 

significant subsurface information to be considered during geotechnical

analysis. Include a paragraph that summarizes the Geotechnical informationand any readily identifiable geotechnical problems or concerns. It may be

appropriate to submit cross sections of such problem areas or concerns

showing conceptual treatments. This information will receive a preliminary

QC review for format, content and completeness.

2.  Informal Discussion of Geotechnical Data to be Considered and Analyses to

 be Performed by means of Geotechnical Working Meetings

After submission of the data and prior to the consultant’s formal evaluation of 

geotechnical findings and results, informal discussions will be held to reviewthe data at one or more geotechnical working meetings. Parties to the

discussion may include the PTC, General Engineering Consultant (GEC), the

Design Manager, the geotechnical consultant, and the designer. Collectively

geotechnical representatives of the PTC, the GEC and the Design Manager arereferred to as the Geotechnical Design Management Team (GDMT).

PennDOT representatives will be invited to participate where applicable. As a

result of this discussion, geotechnical concerns will be identified for further evaluation. The need/requirement for detailed analysis of geotechnical

information will not be warranted if the outcome is predictable from review of 

the basic data.

Informal discussions will arrive at a consensus as to the geotechnical

concerns, further geotechnical evaluation needs and geotechnical design

recommendations anticipated from this effort. The geotechnical consultantwill prepare and distribute minutes of the meeting discussions. The meeting’s

conclusions and issues for further analyses, with a schedule of action items

(e.g., further drilling, testing, study, analysis, etc…) will be submitted with themeeting minutes.

Larger projects requiring significant earthwork, such as off-alignment and total reconstruction projects, may warrant an additional separate cross-section

review meeting. This meeting would be a follow-up to the initial review of 

data meeting.

3.  Draft and Final GER Submission

The GER generally follows PennDOT Pub 293 with several simplifying changesthat include:

•   No straight-line diagram.

•   No repetitions from chapter to chapter - keep it brief.

•  ALL recommendations are in Chapter 2 as a concise list or table.

•  Recommendation list does NOT have to follow the PennDOT outline list.

•  Structure reports are completely separate - information from the structurereports are not to be reiterated in the GER. Instead, identify the structures on

the project and the respective separate reports to be prepared.

The submission is expected to include the report, geotechnical treatment plan,subsurface profile plans, draft details and draft special provisions for construction.

It should build upon the previous Reconnaissance Plan, PSDEP, and Geotechnical

Data submissions.

Maintain consistency among cross sections (basis for construction), geotechnical

treatment plan (pictorial rendering with caveat), tables (if/as necessary – e.g.; coal),details (show limits) and text (if/as necessary). Example geotechnical special

 provisions and details are available upon request. A list of current sample

specifications will be provided upon request.

The report itself should be kept to a minimum by avoiding repetitive text while still providing appropriate documentation to support the recommendations (including

relevant meeting minutes). Incorporate figures and tables within the body of thereport or at the end of the text, but not a mixture of both.

The following items are to be provided in the report, IN THE ORDER PRESENTED BELOW:

1.  INTRODUCTION – Include project location and description. This should be a

 brief overview discussion, of not more than three paragraphs. Provide thegeneral conditions, features, and any relevant items of note.

2.  RECOMMENDATIONS – This is a concise summary of the geotechnicalrecommendations, referencing the Geotechnical Treatment Plan and including a

list of applicable special provisions and construction details, a list of the

construction notes to appear on the plans, and design guidance (includinggeotechnical parameters) for the engineer. In order to expedite the design, use

the Commission’s Construction Standards and Specifications as a basis for 

recommendations. Discuss deviations with the GDMT prior to making formal

revisions.

• Embankment Construction.

•  Cut Construction.

•  Use of On-Site Materials.

•  Transition Zones and Subgrade Construction.

•  Pavement Design Parameters.

•  Special Treatments Not Listed Above.

•  Instrumentation for Construction Control.

•  Additional Testing, Study and Analysis needed for Final Design.(Applicable when a Preliminary GER is prepared during preliminary

design on major projects.)

3.  ANALYSIS OF DATA AND CONCLUSIONS – Prepare this chapter togenerally parallel Chapter 2.0 Recommendations on a section-by-section basis. This is an analysis of the field and laboratory data and assessment of 

the site conditions, subsurface investigations and laboratory findings. The

analysis and interpretation must support the conclusions. Minimize

geotechnical analysis where standardized details and specifications areapplicable. During the analysis and design process, identify the basis for 

using any value, parameter or procedure, e.g., laboratory test results,

reference material and/or engineering judgment.

Identify and estimate the amount of each rock type available from project

excavations, i.e., Type B Rock, Type C Rock and Shale. The sum of thesematerials will equal the total amount of rock excavation. Assume that rock 

layers thinner than 10 ft can not be excavated cleanly without mixing with

surrounding material and assign an appropriate average material type

designation. Include these calculations with the appendix.

The conclusions are to be developed from the analysis. The conclusions

shall be concise, specific and supporting of each recommendation. Do notrepeat recommendations in this chapter.

Include in this section, a brief statement as to why items or issues common

to the project’s general area are not addressed in the report. Examples arekarst conditions, coal mines, oil & gas wells, etc.

4.  SOIL, ROCK AND HYDROLOGIC SETTING – Provide a concise,

integrated summary of findings of the office investigation, field 

reconnaissance, test drilling and laboratory testing, as they relate to

 proposed roadway construction. The section will include:

•  Regional Physiography and Topography.

excavation for the project. Include a cover sheet containing a list of personswhose initials appear on the calculations, with a statement prepared, signed and sealed by a Professional Engineer, registered in the Commonwealth of 

Pennsylvania, that all calculations are checked.

C.  Deliverable

The GER submission can be made in one or more volumes, depending on its

overall size. The deliverables are to be submitted as electronic pdf files.Bookmarks within the pdf file should be provided for each section and appendix

of the report. Additionally, a hardcopy of the final submission is required. If a

multi-volume submission is made, provide the report text and Appendix A, B, and C as the first volume. On larger projects, Appendices D – Plan of Borings with

Reconnaissance Notes and Mapping, E – Test Boring Records and F – Laboratory

Test Results can be submitted at the Informal Discussion of the Geotechnical Datameeting. If there are no revisions, then the boring logs and lab testing data will

not have to be resubmitted with subsequent hard copy submissions. However,

these appendices are required with subsequent electronic pdf file submissions

The GER will be modified in response to comments on the Draft GER 

submission. Modifications can be made through submission of individual pages

or report sections, for approval. After approval of modifications is received, provide a complete final GER submission.

8.4 Soil Profile Plan Submission Guidelines

A.  Objective

The Soil Profile Plan is to be prepared to provide an illustrative view of the

subsurface conditions across the project. It is to be considered a tool to identify

and communicate subsurface conditions of concern, potential sources of materialrequired for construction, material located at the bearing elevation of proposed 

structures; and support the construction of the project. The Soil Profile Plan will

 be incorporated into the PS&E as a set of “Also Plans”.

This submission may not be required on single bridge projects. Such projects have

limited subsurface information which is adequately shown on the structuretracings of all borings.

8-13

Oct 201

B.  Scope of Work 

A soil profile is a restatement of subsurface boring information which generally

emphasizes the vertical axis or elevation and deemphasizes the horizontal and is usuallyoriented along the construction or stationing centerline. Because of the orientation being along the construction or stationing centerline, the subsurface profiles are

typically aligned perpendicular to major structural features.

Where more than one boring is at or near the same station, show the subsurface boring

information on the closest regularly spaced cross section. Borings nearest the project

centerline will appear in both the subsurface cross sections and profile. Show only

those cross sections which have boring information. Borings which do not appear oneither the subsurface cross sections or profile should be shown on a separate sheet(s).

Include the following on the Soil Profile Plan:

•  Centerline with stationing along the x- axis and elevation to mean sea level alongthe y-axis for the profile.

•  Correct elevation and stationing of project structure locations.

•  Existing and finished ground lines.

•  Correct elevation, stationing and offset of project boring.

•  Proper soil and bedrock symbols for units encountered in the boring on graphical

logs, plotted at proper elevation (No black-line boring log, must be graphical log.

 No different scale log, must be same scale as profile.).

•  Correct groundwater elevation. Provide note at the bottom of the boring if it was

dry or that water was not encountered.•  Correct normal pool elevation of water body (if encountered).

•  Potential sources and estimated quantity (or quantities) of rock available within the project limits that may be required for stability and/or drainage.

•  Significant geologic formations and/or seams, e.g., Morgantown Sandstone,Pittsburgh Coal.

•  A note indicating that the Soil Profile Plan is to be used for informational purposesonly.

C.  Deliverable

The deliverable is submitted as draft and final submissions with the GER. The draftsubmission is reviewed and comments are provided. The final submission addresses the

comments and serves as the final Soil Profile Plan for the project.

8.5 Geotechnical Treatment Plan Guidelines

A. 

Objective

The Geotechnical Treatment Plan’s (Also Plans) purpose is to present

recommended geotechnical treatments which impact the design and construction

of the roadway and its associated structures. The objective of the GeotechnicalTreatment Plan is to provide an efficient description of geotechnical design

features that must be incorporated into the construction effort.

The draft Geotechnical Treatment Plan is to be developed (as necessary) for geotechnical treatments identified at the Design Field View. The final

Geotechnical Treatment Plan is to be incorporated as a set of “Also Plans” in the

PS&E. They are to be sealed by an Engineer registered in the Commonwealth of Pennsylvania.

B.  Scope of Work 

The Geotechnical Treatment Plan is an index or overview “working drawing”.

For each Geotechnical Treatment Plan use/show:

1. Scale of 1”=200’

2. Topographic base map with alignment, cut/fill limits, roadways and structures.3. Anticipated locations of the types of treatments along with the limits of such

treatments.

4. North arrow.5. Title block.

6. Existing and Proposed Structures

C.  Deliverable

The deliverable is submitted as draft and final submissions with the GER. The

draft submission is reviewed and comments are provided.

8.6 Structure Foundation Submission Geotechnical Report Guidelines

A.  Objective

The structure foundation submission consists of a letter, foundation plans,geotechnical report and the QA Form D-505.

Page 120: pa turnpike design consistancy manual 2011

7/14/2019 pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 120/208

8-15

Oct 201

Typically, the letter references the geotechnical report, foundation plan, and the QAform as attachments. The purpose and objective of the Structure Foundation

Geotechnical Engineering Report (SFGER) is to provide the structure engineer with the parameters used to develop the design, geotechnical constraints on structure design(e.g.; settlement, stability, etc), and geotechnical notes and details related to

construction of the structure.

The geotechnical report includes the foundation plans and QA Form D-505 as

appendices.

B.  Scope of Work 

The process from collection of field data to foundation approval can be expedited 

through the use of three major steps:

1.  Collection and Submission of Data to be used for Foundation Design

Upon completion of the boring and testing programs, submit draft versions of the

as-drilled boring location plan, typed engineer’s boring logs, and relevant boring

 profiles. Submit a summary of soil, rock and water testing performed, along with

the raw test data. Reference the date of the boring and testing program approval,and note any major discrepancies. Also submit other significant subsurface

information to be considered during foundation analysis (prior to Com 624,

ABLRFD, and similar computer analyses). This information will receive a preliminary QC review for format, content and completeness.

2.  Meetings to Informally Discuss Foundations to be Considered and Analyses to bePerformed 

After submission of the data and prior to formal evaluation of foundation

alternatives, a meeting (or meetings on multi-structure projects) will be held toreview the data. Depending on the project, parties to the discussion may include the

PTC, GEC, and/or the Design Manager, collectively known as the Geotechnical

Design Management Team (GDMT); the design engineer, the geotechnicalconsultant, and the structural designer. PennDOT representatives will be invited to

 participate where applicable. As a result of this discussion, foundation alternatives

will be identified for further evaluation, including cost comparisons, as warranted.The requirement for detailed analysis of any foundation alternative will not be

warranted if the outcome is predictable from review of the basic data.

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 121/208

8-16

Oct 2011

The alternative analyses will be summarized, and submitted for concurrence.

Informal discussions will arrive at a consensus as to the foundation type(s)and the general substance of the geotechnical foundation recommendations.

Maintain coordination with the GDMT during analyses. Perform technicaland economic comparisons for the various options considered only whenapproved.

The geotechnical consultant will prepare and distribute minutes of thesediscussions and meetings.

3.  Draft and Final Foundation Submission

The submission is expected to include all four major components and meet the

submission requirements of PennDOT DM-4. The following items should be

covered in the SFGER, IN THE ORDER PRESENTED BELOW:

1.  INTRODUCTION – Include project location, structure description, and 

site description. This should be a brief overview discussion, of not morethan three paragraphs. Provide the general conditions, features, and any

relevant items of note.

2.  RECOMMENDATIONS – This is a concise summary of the geotechnicalfoundation recommendations, including the summary table required by

DM-4 subsection 1.9.4.3(a), a list of applicable special provisions and 

construction details, a list of the foundation notes to appear on thestructure plans, and design guidance (including geotechnical parameters)

for the structural engineer. Place the table at the front of the text for this

chapter; not at the end of the report. In order to expedite the design, usethe Commission’s Construction Standards and Specifications as a basis for 

recommendations. Discuss deviations with the GDMT prior to making

formal revisions. Minimize geotechnical analysis where standardized 

details and specifications are applicable.

3.  SPECIAL CONCERNS - Provide a paragraph on any special geotechnical

concerns identified. This may include stability, settlement, mining, karst,or other concerns.

8.7 PS&E Review Guidelines

A. 

Objective

The purpose of the Plans, Specifications and Estimate (PS&E) review is to review the

draft contract documents to make sure that the design criteria and specifications

contained in the plans, details, and cross sections accurately meet the geotechnicalrecommendations for the project. The objective of the review is for the contract

documents to achieve concurrence with the geotechnical recommendations so the

 project may advance forward.

B.  Scope

A PS&E review consists of a review of the draft contract documents conducted by thegeotechnical representative responsible for or tasked with the geotechnical portion of 

the project. The geotechnical representative is to review the Pre PS&E’s plans, special

 provisions, details and cross sections for accuracy and ensure that the geotechnicalrecommendations are being correctly interpreted in the design.

C.  Deliverable

The deliverable is to be a QA/QC form signed by the Geotechnical representative and 

the Designer that acknowledges the review has been completed and that the PS&E

documents appropriately incorporate the geotechnical recommendations. This form isto be submitted with the PS&E documents. A sample form is provided as an attachment

at the end of the Design Consistency Guidelines.

8.8 Miscellaneous

A.  Notes for PTS-100 Use

PTS-100 is intended as a guide for embankment bench design and construction. It is

not intended to replace project-specific analysis of proposed embankments. The limits

and dimensions shown on the details may be modified to ensure adequate stability based on project-specific analysis. The minimum factor of safety required for 

embankments is 1.3. For embankments within 50 ft of a structure the minimum factor 

of safety is 1.5. It is recognized that problematic areas may exist where the minimumfactor of safety can’t be obtained through reasonable design approaches. In these areas,

the minimum global stability after construction is required to be at least equal to

existing embankment’s stability. This may require back-analysis of existing conditionsto determine appropriate assumptions. It is important that the existence of this condition

 be captured in correspondence to the Designer and PTC. Include the extent and limitsof where this situation occurs within the project.

B.  Guidance for Rock Embankment Design

Attempt to utilize on-site materials for embankment construction and avoid a borrow condition. The rock types identified in the PTS standards were selected to perform adequately in cases where geotechnical information is limited or absent.

The Geotechnical designer should evaluate if an onsite rock type of lower quality

is adequate for stability. The future performance of on-site embankment materialscan be aided by observing the performance of existing Turnpike embankments.

Much of the Turnpike has 1½:1 H:V stable slopes which were constructed from

onsite material.

In the GER (but not in contract documents) identify and estimate the amount of 

each rock type available from project excavations, i.e., Type B Rock, Type C

Rock and Shale. The sum of these materials will equal the total amount of rock excavation. Assume that rock layers thinner than 10 ft can not be excavated 

cleanly without mixing with surrounding material and assign an appropriate

average material type designation.

Attempts should be made to utilize readily available rock types for construction

 provided that adequate stability is maintained. In the event that such rock types

do not fit the strict definition of Type A, Type B or Type C Rock, then projectspecific special provisions can be written to allow the use of a suitable project

specific rock type. For example, a “Type B-Modified Rock” special provision

could be developed to permit the use of either a hard siltstone or a suitablelimestone. The Designer should request permission from PTC-Geotech to pursue

a modified type rock material and only allowed from project excavations. This

request should be accompanied by boring logs and testing as justification.

The Contract will define the rock embankment requirements for construction but

not to define the source location of the rock. The only information to be provided 

regarding the source of the rock types is in the Soil Profile Plan (included in theContract as Also Plans). Here the laterally continuous and substantially thick 

layers (greater than 10 ft) are labeled without any markings delineating the upper,

lower or lateral boundaries. However, the Contract should be clear as to thegeneral acceptability of onsite material for construction of embankments,

especially, steepened embankments. 

The Geotechnical designer should work closely with the roadway design team as

the rock embankment requirements (toe bench, drains, blanket, etc.) are being

 placed on the contract documents.

Type A Rock 

The vast majority of projects do not contain sufficiently thick layers of Type A Rock 

which can be excavated cleanly. Therefore, unless otherwise approved by PTC-Geotech, assume that all Type A Rock specified for a project will be obtained from anoutside source. The utilization of Type A Rock should be limited to areas where

significantly high drainage flow is anticipated or high strength is required, i.e., 1:1

embankment. In the contract, provide a borrow quantity for the amount of Type A Rock required for construction. Use typical strength parameters in the range of phi = 40 to 45

degrees or higher for Type A Rock design.

Type B Rock 

In order to access the constructability of a project, during design, tabulate the quantity

of Type B Rock available from the project excavation. Do not consider seams less than10 ft thick or seams that are not greater than 90% pure in the tabulation. Furthermore,

use a reduction factor of: 20% for seams 10 to 15 ft thick; 15% for seams 15 to 20 ft

thick; and 10% for seams over 20 ft thick. Identify in-situ locations and quantities of Type B Rock available. Make comparisons between the rock available from

excavations and the rock required for construction. If appropriate, consider staging.

Type B Rock is acceptable as rock toe material, even below drainage, where conditionsare anticipated to be saturated and/or with normal seepage. The typical strength

 parameter range for Type B Rock is phi = 36 to 40 degrees.

Type C Rock 

Type C Rock is an uncontrolled mixture of all rock available on the project excludinglarge quantities of slaking claystone, redbeds, and other forms of clay, silt, sand or mud.

In some situations, Type C Rock can be specified for use when other rock types are not

available. Typical strength parameters can not be readily defined because of the project

specific nature of this rock type.

C.  Dynamic Pile Load Testing Guidelines

GENERAL

A.  Driving in accordance with Section 1005.B.  Drive test and/or bearing piles to absolute refusal, unless otherwise indicated or directed.C.  The amount of Dynamic Pile Test locations is to be determined according to the

characteristics of each structure. Specify two (2) tests per substructure unit unless

otherwise directed .D.  The Engineer may request additional piles to be dynamically tested if the hammer and/or 

driving system is replaced or modified, the pile type or installation procedures aremodified, the pile capacity requirements are changed, unusual blow counts or 

 penetrations are observed on any other piling behavior different from normal installation.

E.  When the wave equation supplemented with stress wave measurements and CAPWAP analyses is used to predict the pile capacity, the product of a resistance

factor of 0.7 times the predicted ultimate axial pile capacity must meet or exceed the maximum factored axial pile load shown on the plans.

EQUIPMENT

Use a hammer and capblock which produces an acceptable driving stress range of 60%to 90% of the yield strength of the steel, at absolute refusal.

EXAMPLE

Determining the Allowable Stress Range*

 for Steel H Piles:

Yield Stresses (f y 

= steel yield strength in ksi):

for ASTM A36 (f yfor ASTM A572 or A690, Grade 50 (f 

= 36 ksi)y

 = 50 ksi)

Calculation of Driving Stresses:

Using ASTM A36:0.60 x f y0.90 x f 

= 0.60 x (36) = 21.6 ksi

y

 

= 0.90 x (36) = 32.4 ksi

Therefore the driving stresses should range between 22 ksi to 32 ksi for ASTM 36 steel;

or between 30 ksi and 45 ksi for ASTM A572 steel.

Driving stress range applies to both Special Provisions "Piles" and "Dynamic Pile Load Testing".

Chapter 9 - PAVEMENT DESIGN

9.0  Permanent Pavement – Flexible Pavement

A. General

The pavement analysis and design shall be completed in accordance with the

following guidelines and in conjunction with the policies and procedures provided

in the AASHTO Guide for the Design of Pavement Structures and the PennDOTPublication 242, Pavement Policy Manual, hereinafter referred to as AASHTO

and Publication 242, respectively. The pavement design computations shall be

conducted using AASHTOWare DARWin 3.01 software, hereinafter referred to

as DARWin.

The use of the publications noted above does not preclude the application of 

engineering judgment for any unusual situations or problems that may be

encountered on a specific project. Federal, state or local regulations may alsorequire deviations from the aforementioned guidelines. All deviations from these

 policies and design procedures must be fully documented.

B. Flexible Pavement Design Guidelines

All permanent flexible pavement projects are currently being designed usingSuperpave mix design specifications for wearing and binder. The selection of the

PG-binder is to be in accordance with Commission Specification, Section 409.

For all Turnpike mainline paving, use an asphalt mixture with a 10 to <30 million

ESALs design life for binder and wearing courses. All pavements are to utilize

SRL-E wearing courses.

All projects are incorporating a minimum pavement structure comprised of two(2) inch wearing course and three (3) inch binder course layers, a bituminous

concrete base course layer of variable depth (to be computed), a four inch

drainage layer of asphalt treated permeable base course, and a six (6) inch subbase

layer. The bottom four (4) inches of bituminous concrete base course shall be a“rich bottom mix”. The “rich bottom mix” is achieved by adding additional PG

64-22 asphalt, and will require utilization of the PTC’s Special Provision.

The bituminous concrete base course layer is the only pavement layer that varies

significantly in depth from project to project. The depth of the base course layer is not only a function of the anticipated traffic loadings but also of the subgrade

soil conditions. This is consistent with the Publication 242 design approach for flexible pavements on weak subgrade soils, which is to provide a stronger base

course able to withstand the effects of lower bearing support in the subgrade soils.

It is this layer that is adjusted to provide the needed structural strength required bythe pavement design.

Page 129: pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 129/208

9-2

Oct 2011

Roadbed soil testing must be conducted to evaluate the condition of the roadbed

soil. Areas of low subgrade support and/or frost heave susceptible soils must be

identified. Procedures used to improve subgrade support where needed, such asundercutting or subgrade stabilization, must be analyzed and the most feasible

and economical solution chosen that does not reduce pavement thickness.

Methods to reduce the detrimental effects of frost heave on the pavement, suchas undercutting or increasing pavement base course layer depth, shall beconsidered and the most feasible and economical solution chosen. Refer to

Chapters 3 and 5 of Publication 242 for additional guidance on subgrade soil

evaluation procedures.

The following pavement layers are the minimum to be used on any Total

Reconstruction project:

  2-inch Bituminous Wearing Course SRL-E, Superpave (12.5mm)

  3-inch Bituminous Binder Course, Superpave (19mm)

  10-inch Bituminous Base Course, Superpave (25mm)  4-inch Asphalt Treated Permeable Base Course

  6-inch Subbase (No. 2A)

  25-inch minimum depth

The thickness of the Bituminous Concrete Base Course will be determined by

subtracting the difference between the required structural number of the entire

 pavement structure and the structural number of the other pavement layers.

C. Permanent Pavement Design Parameters

This section describes the Design Parameters recommended for use in the designof permanent flexible pavements. For the most part, the parameters given are to

 be standard for all projects; however, there are specific parameters that must be

determined by the designer. For example, traffic input parameters must becalculated from traffic data provided by the Commission, and roadbed soil input

 parameters must be determined from various test results of soils from the project

area. These computed parameters are noted in Table 9.1.1.

The selection of the design parameters for input into the DARWin softwareshall be in accordance with Chapters 6, 7, and 9 of Publication 242. The ESAL

Calculation method in DARWin shall be used to compute the total 18-kip

ESALs for a project’s performance period. The Compounded Growth Ratecalculation method in DARWin should be used to determine the total 18-kipESALs unless historical evidence or traffic studies show a linear growth trend. If 

a linear growth trend exists, then the Simple Growth Rate calculation method in

DARWin should be used. Use either the Specified Thickness Design method

or the Optimized Thickness Design Method in DARWin to determine the pavement layer thicknesses.

9.1 Permanent and/or Temporary Median and Outside Shoulders - Flexible Pavement

The following minimum pavement structure is the standard for permanent shoulders:

  2-inch Bituminous Wearing Course, Superpave (12.5mm)

 3-inch Bituminous Binder Course, Superpave (19mm)

  4-inch Bituminous Base Course, Superpave (25mm)

  6-inch Subbase (No. 2A)

This standard pavement structure has a structural number of 4.46. If traffic will berunning on the shoulder, a pavement structure must be designed based on roadbed soil

conditions, traffic, and the duration of time that traffic is running on the shoulder. The

 permanent shoulder pavement shall be designed using the same roadway pavement

design parameters as detailed in Section 9.0B. The structural number of this pavementdesign shall be checked against the standard 4.46 structural number. If the required

shoulder structural number is less than the minimum 4.46 structural number, then the

standard (minimum) pavement structure shall be used. If the required shoulder structuralnumber is greater than the minimum (4.46) structural number, then the subbase depth will

 be increased to a maximum of 12-inches until the required structural number is met. If 

the required structural number is not achieved using 12-inches of subbase, adjust both theBCBC depth and subbase depth to achieve the most economical design.

For two-stage construction, signing to keep trucks and buses out of the right lane is

typically used as part of the maintenance and protection of traffic. A value of 25% trucksshould be used for the percentage of all trucks in the design lane for the shoulder 

evaluation. The temporary pavement design parameters to be used are provided in Table

9.3.1.

If the maintenance and protection of traffic scheme uses the existing shoulders as part of 

the traveled way, then the structural number requirements must be met in addition to

surface milling/overlay work to provide ride quality, if necessary. If these requirementscannot be met, then a temporary pavement shall be designed to accommodate the

anticipated traffic loadings.

For projects such as an overhead bridge replacement, which requires traffic to run on the

existing median or shoulders for a short length of time for maintenance and protection of 

traffic purposes, no pavement design is needed. A temporary pavement consisting of a 2inch bituminous wearing course layer on a 6 inch bituminous binder course layer should

 be utilized for the short-term traffic pattern.

9.2 Permanent Pavement for Local Roads and State Routes

Turnpike construction that impacts local or state route roadways will require a pavement

design for the replacement pavement structure or rehabilitation (e.g. mill/overlay) for the

impacted side roads. For local roads, the local municipality ordinances must bereviewed to determine the appropriate design and materials for the rehabilitation or replacement pavement structure. If local ordinances are not available, Publication 242

guidelines shall be followed. The pavement design of the Pennsylvania states routes

impacted by Turnpike construction shall be completed in accordance with Publication242. The pavement design of local routes and states routes must be reviewed and

approved by the local municipality and PennDOT, respectively.

Chapter 10 – GUIDE RAIL AND MEDIAN BARRIER 

10.0 Introduction

These guidelines are based on a review of the 2011 AASHTO Roadside Design Guide, the2009 Edition of PennDOT Publication 13M, Design Manual Part 2, Highway Design, current

PennDOT Publication 72M – Roadway Construction Standards, Pennsylvania Turnpike

Commission Standards for Roadway Construction, discussions with and training by FHWAin May and October of 2000, and existing PTC practices for the design and installation of 

guide rail on the Pennsylvania Turnpike.

The use of these guidelines should be reviewed for conflicts with more current standards.

The following information and criteria are guides and should be supplemented with sound 

engineering judgment. For additional guidelines, refer to the Standards for typical guide rail

and median barrier placement and installation details. Reference should also be made to thesource references listed above.

As written in the introduction to Chapter 12 - Guide Rail, Median Barrier, and RoadsideSafety Devices from PennDOT Design Manual Part 2:

“Highways should be designed through judicious arrangement and balance of geometricfeatures to preclude or minimize the need for roadside or median barrier. To provide for 

maximum roadside safety, a thorough study during the early stages of design is necessary to

recognize and eliminate, where practical, those items and conditions which require barrier and impact attenuating devices.

While every reasonable effort should be made to keep a motorist on the roadway, the

highway design engineer should acknowledge the fact that this goal will never be fullyrealized. Motorists continue to run off the road for many reasons, including driver error in

the form of excessive speed, falling asleep, reckless or inattentive driving, or driving under 

the influence of alcohol or other drugs. A driver may also leave the road deliberately toavoid a collision with another motor vehicle or with objects on the road.”

The following guidelines should be applied for the design of guide rail and end treatmentinstallations on the Pennsylvania Turnpike. Guide rail and end treatment installations on

state and local roads should follow the procedures as described in the current PennDOT

Design Manual Part 2.

The guidelines discussed in the PennDOT Design Manual Part 2 and the AASHTO Roadside

Design Guide should be used for guide rail and end treatment installations not addressed in

this chapter.

10.1 Guide Rail

A. General

Installation of guide rail is to be measured on a geometric line in conjunctionwith the white solid line (edge of travel lane). (Measurement should be along

the survey and construction baseline.)

Guide rail is to be installed as far off the roadway as practical. The back edge

of the existing paved shoulder will be the minimum distance from traffic that

guide rail is to be installed.

Guide rail currently located outside of the determined Clear Zone should be

evaluated for possible removal. Specifically, guide rail at the back edge of a

 pull-off area should be reviewed to determine if a hazard/obstruction is present behind the existing run of guide rail.

The preferred methods, in order of preference, of terminating the approachend of guide rail are by burial or by Vehicle Attenuating Terminal End 

Treatments (VATETs), except at Maintenance Openings.

Flared VATETs (PennDOT Gating Type II) are to be installed according toFigure 10.1.1 and are preferred on tapered runs of guide rail.

Parallel VATETs (PennDOT Gating Type III) are to be installed on a straightline and are preferred on parallel runs of guide rail.

Parallel VATETs for two-way traffic (PennDOT Gating Two-way TrafficType IV) are to be installed on a straight line and are preferred on parallel

runs of guide rail. Application would typically be in gore areas at deceleration

ramps and in gore areas where traffic splits directionally (directional ramps

B. Clear Zone Concept

For Clear Zone information, refer to the PennDOT Design Manual Part 2,

AASHTO’s “A Policy on Geometric Design of Highways and Streets,” and the AASHTO Roadside Design Guide.

C. Slopes

For guide rail installation on fill slopes, refer to the PennDOT Design Manual

Part 2, AASHTO’s “A Policy on Geometric Design of Highways and Streets,”

and the AASHTO Roadside Design Guide.

D. Tapers

Guide rail is to be tapered at 30:1 when the guide rail is located inside the shy

line until either the guide rail reaches the shy line distance or the guide rail

reaches the back edge of the paved normal shoulder, whichever is greater.The shy line is defined as the distance from the edge of the traveled way,

 beyond which a roadside object will not be perceived as an obstacle and result

in a motorist reducing speed or changing vehicle position on the roadway. For 

a roadway with a 70 mph design speed, the shy line distance is 10 feet fromthe edge of the white line.

Guide rail is to be tapered at 15:1 outside of the shy line unless a parallelguide rail installation is more practical. A 10:1 or flatter slope must be

maintained in front of guide rail tapered at 15:1. If the grading necessary to

maintain the 10:1 or flatter slope in front of the guide rail is more than whatwould be considered incidental to the installation of the guide rail, then note

and include a quantity for this grading.

E. Outside of Horizontal Curves

These guidelines are based on the Pennsylvania Turnpike mainline curvature,

which generally does not exceed six (6) degrees.

Guide rail runs should be determined by using the Length-of-need (LON)

calculations and applying the curve correction factor.

Parallel runs of guide rail should be measured concentrically from the white

solid line with the approach end terminated by burying into the backslope or with a VATET suitable for a parallel installation.

Page 144: pa turnpike design consistancy manual 2011

http://slidepdf.com/reader/full/pa-turnpike-design-consistancy-manual-2011 144/208

10-9

Oct 201

Tapered runs of guide rail should be tapered as measured from the white solid lineat 15:1 over flat grading (10:1 or flatter with 10:1 the most common grade) and 

drawn to scale on the plans. Offsets for the Type II, Flared VATET are measured off the tapered line extended.

F. Inside of Horizontal Curves

The guidelines described in the section "Outside of Horizontal Curves" are to be

applied to guide rail installed on the inside of horizontal curves.

Do not use “Horizontal Curve Adjustments” for calculating clear zone widths onthe inside of curves.

G. Length of Need Equation

In an area where multiple hazards/obstructions (bridge abutment or parapet fill,

slopes 3:1 or steeper, endwalls, etc.) are located in close proximity to one another, aLON calculation is to be performed for each hazard/obstruction to determine the

greatest LON distance for that area.

LON calculations are to be performed per the current PennDOT Design ManualPart 2 for each run of guide rail, except where guide rail is being buried in a non-

traversable cut slope.

Use the shoulder width at the obstruction (distance from the white solid line to the

face of the obstruction) for the L2 value in the LON equation.

In locations where the guide rail must be tapered at a rate of 30:1 to reach either the

shy line or the back edge of the paved normal shoulder, include that length of guide

rail tapered at 30:1 with the tangent length of barrier upstream from the obstruction

to determine the L1 value in the LON equation.

Use the 15:1 taper rate in the LON equation (i.e.: b=1 and a=15). For ramp LON

equations, adjust the taper rate in accordance with the ramp design speed.

The portion of the VATET length to be included as part of the guide rail LON is 25

feet.

H. Recommended Clear Runout Area Behind VATET

Provide the manufacturer's recommended clear runout area behind a VATET.

If the recommended minimum clear runout area is not achievable, or the

economic cost to achieve the minimum value is determined to be restrictive,

then modify the run of guide rail for an acceptable solution without lesseningthe total length of guide rail below the calculated LON value.

I. Burying of Guide Rail

Earth mounds are not to be created for the burying of guide rail.

A concrete anchorage back slope is to be used to bury the guide rail as shownon the Standard Drawings. Where guide rail is to be buried in the roadway cut

slope, extend the guide rail a minimum of 75 feet beyond the cut/fill line at a

taper rate of 15:1, parallel, or a combination thereof. This combination of  parallel and 15:1 tapered guide rail can be used for up to 112.5 foot run. The

taper can start prior to the cut/fill line as long as the taper runs a minimum of 

75 feet past the beginning of the cut slope. A 10:1 slope must be maintained 

in front of guide rail.

When the width needed to bury the end anchorage necessitates a taper length

greater than or equal to 125 feet, install the last 50 feet (or "quick taper") per 

the PennDOT Standard Drawings, RC-54M. Extend the guide rail for a

minimum of 75 feet beyond the cut/fill line at a taper rate of 15:1, parallel, or a combination thereof prior to the "quick taper."

For rock slopes 1:1 or steeper, a Terminal Section, Bridge Connection may beused in lieu of burying the end treatment if the nature of the rock slope is that

which would make burying the end treatment not practical or desirable. If a

Terminal Section, Bridge Connection is proposed, the rock at the location is to be reviewed by a Geotechnical Engineer to determine if the rock is compatible

with the anchor bolt connection.

Guide rail may be buried behind the front face of a slope which is 2:1 or steeper. The 75-foot minimum guide rail length is not required here.

J. Trailing End of Guide Rail

The preferred methods, in order of preference, of terminating the trailing end of guide rail are by a Type 2-S Post Anchorage per the Standard Drawings, or 

 by running the guide rail 50 feet past the hazard/obstruction so that full

tension is developed. A Terminal Section, Single is to be installed on guiderail runs 50 feet past the hazard/obstruction.

K. Drainage Features

If a headwall is required, the headwall is to be installed outside the Clear Zone or at

a distance greater than the recommended deflection rate of the guide rail.

Pipes not protected by guide rail are to be extended, where practical, outside the

Clear Zone.

Drainage ditches, which must be placed inside the Clear Zone, are to be designed to

 be traversable if they are not protected by guide rail.

The preferred methods, in order of preference, of addressing an existing drainage

ditch located inside the Clear Zone are by regrading the ditch such that the ditch is

traversable, relocating the ditch outside the Clear Zone, extending existing drainage

 pipes to be outside the clear zone, installation of end sections, or installing guiderail. General engineering judgment should be utilized in determining designed 

drainage layout. Extension or realigning of drainage features may require the U.S.

Army Corp of Engineers or a PaDEP permit.

L. Rounding of Guide Rail Panel Lengths

Always round up to the next full guide rail panel (12.5 feet) when determining thetotal length of guide rail required in each individual run of guide rail.

M. Treatment of Guide Rail Where Access Ramps Meet the Turnpike Roadway

In cases where the guide rail LON would continue past an Access Ramp entrance,install guide rail as shown for a Driveway Entrance on the PennDOT Standard 

Drawings, RC-54M.

In cases where the guide rail LON would end on an Access Ramp entrance, theoptions to treat this condition would be to install a VATET before the Access Ramp

if the hazard necessitating the guide rail can be moved downstream from the Access

Ramp, or install a Driveway Entrance as described above.

N. Treatment of Guide Rail at Maintenance Opening

A Maintenance Opening is defined as an opening in a run of guide rail to allow theCommission's Maintenance Forces access to perform routine maintenance (mowing

of grass, etc.).

Install the Maintenance Opening as shown on the Commission Standard Drawings,PTS-130.

A Type 2-S Post Anchorage is to be used at the guide rail approach and trailing end 

treatment at the Maintenance Opening.

10.2 Concrete Median Barrier and Single-face Barrier

In general, concrete median barrier and single face concrete barrier is to follow the

design guidelines for guide rail in section 10.1 when determining Clear Zone needs.Taper rates are to be per the standard drawings. Shy line taper rates are to be per section 10.1.D of guide rail.

A. Concrete Median Barrier

1. Mainline

•  Typically, all median barriers are to be 52-inch concrete glare screen per the RC standard drawings.

•  Typically, all median barrier transition sections, tied to various typesof existing barriers at either end of the project, are to be per the PTS

standards.

2. Interchange Ramps

•  Typically, all median barriers on two-way ramps are to be 34-inchconcrete median barrier per the RC standards.

•  For curves with a radius equal to or less then 250 feet specify five-foot barrier sections from the PC to the PT

Where the two-way ramp split into two single ramps, the 34-inch

concrete median barrier should be designed to follow the deceleration

ramp and taper away from this ramp at the appropriate taper rate for the design speed of this ramp.

Following this procedure, the barrier will typically end in the middleof the gore area between the ramps. An impact attenuator is to be

 placed on the end of the barrier at a point outside the calculated Clear 

Zone of the deceleration ramp pavement. The gore/shoulder area oneither side of the barrier should be paved and extended a minimum of 

12 feet beyond the attenuator (only on ramps outside the full plaza) to

facilitate the ability for maintenance trucks to turn.

In addition, the drainage in this area is to be designed to ensure that no

 ponding occurs.

B. Single-face Barrier

Utilize single-face barrier on cut slopes and other areas in accordance with theStandard Drawings

Chapter 12 – LIGHTING

12.0 Introduction

This chapter presents the design criteria for the formulation of conventional and high

mast lighting systems. The information herein is written for qualified lighting engineersand to assist them in preparing a uniform and standard lighting design. The designer’s

engineering judgment in the application of the criteria is subject to review and 

concurrence by the Commission. The designer shall obtain prior approval from the

Commission on matters of design which raises questions in the application of thesecriteria to a specific condition.

Sources of reference which may be used in addition to this manual are:

•  Roadway Lighting Design Guide October 2005, or the latest edition – AASHTO.

•  Standard Specifications for Structural Supports for Highway Signs, Luminaires, and 

Traffic Signals – AASHTO.•  Publication 408, Specifications and Associated Changes – PennDOT.

•  Current Standards for Roadway Construction – Highway Lighting Standard 

Drawings, RC-80M, RC-81M, RC-82M, RC-83M, and RC-84M – PennDOT.

•  Current Bridge Construction Standard Drawings, BC-721M and BC-722M – PennDOT.

•  Design Manuals, Part1, Part 1A, Part 2, Part 3, and Part 4 – PennDOT.

•  IESNA Lighting Handbook RP-8-00 Reaffirmed 2005 or the latest edition.

•  International Dark Sky recommendations.

•  Good Neighbor Policy – The Commission would like to maintain good neighbor status with local residents. Consider the impact of lighting on surrounding residential

areas. Avoid light trespass. The standard Commission lighting design is based onHigh Pressure Sodium (HPS), or Metal Halide semi-cutoff luminaires at a 40-foot

mounting height, Full cut-off luminaires and house-side shielding may be considered,

Lower mounting heights may also be considered, but not desirable. The designer should evaluate concerns and present to the Commission for consideration.

•  Local Ordinances – The Commission is considered its own political jurisdiction;however, if local municipalities enforce stricter rules, the Commission may opt to

comply with local ordinances as a good neighbor. The lighting designer will berequired to contact local authorities for their standards.

The Commission will be responsible for all energy and maintenance related costs unless

other provisions are established for these costs. Energy and Maintenance Agreementswith local agencies will be required to establish responsibilities if others will perform

maintenance or supply energy to the lighting system.

During the early stages of design, a pre-design meeting shall be conducted at the

Commission headquarters to discuss lighting design criteria, and to address all project-

specific requirements relating to the highway lighting design.

Page 154: pa turnpike design consistancy manual 2011

12-2Oct 2011

Where existing lighting systems are being partially modified, the new lighting standards

will match the existing system including pole heights, luminaire and arm types, materials,

etc. If possible, existing lighting standards may be reused on new foundations. If  breakaway features are required, current AASHTO requirements must be met.

Lighting systems will be designed and installed to limit light trespass onto adjacent properties. In general, arm-mounted, conventional cobra-head luminaires with cutoff 

optics are preferred over high mast or tenon-mounted luminaires. This preference does

not preclude considering the latter systems. These systems should be considered if other 

factors such as ease of maintenance, light distribution limits, or economic savings supportan improved final product. House–side shielding on luminaires may be used to minimize

light trespass.

Highway lighting designs typically include a conceptual (Lighting Study)   initial, a

 preliminary and a final submission. The conceptual (Lighting Study)  initial submission

should include an evaluation of options and alternatives such as the use of high mast

lighting, conventional lighting and offset lighting within the project. Also included should be the general limits of the proposed lighting, as well as luminaire mounting

height and wattage data, and any required recommendations to avoid light trespass. The

conceptual (Lighting Study) submission should include typical lighting calculations for each lighting type specified. The conceptual (Lighting Study) initial submission

requirement may be waived by the Commission if the project is clearly not suitable for 

high mast or offset lighting, as determined at the pre-design meeting.

Upon approval of the conceptual (Lighting Study) submission, a preliminary submission

should be prepared that includes highway lighting plan sheets indicating each luminairemounting height and offset, and each luminaire location by station.

A preliminary highway lighting report should be submitted along with the plans thatincludes: summary of all lighting design criteria, IES photometric file for the luminaire

and lamp, calculations that indicate the end of rated life average footcandle level,

uniformity ratio and glare ratio for each unique pole spacing in accordance with

PennDOT Design Manual Part 2, Chapter 5. Footcandle calculations shall be provided for ramps, transition zones, toll plaza areas and employee parking lots only. The lighting

of mainline roadways is not required and any lighting falling on these areas is considered 

incidental light. The lighting of shoulders is not required.

 Negative luminaire overhangs (-5-foot, -10-foot) may be considered in the lighting

design; however luminaire overhangs must be consistent within the same area.

The final submission should include final lighting plans, complete with tabulation of 

quantity sheets, circuit wiring diagram sheets, special detail sheets and plan sheets in

accordance with Design Manual Part 3, Chapter 9. Also included in the final submissionshall be wire size calculations, guide rail clearance worksheets, special provisions, cost

estimates and all necessary design information such as roadway cross sections, drainage

 plans, contour grading plans, and bridge structure drawings to allow satisfactory reviewof the lighting design.

12-3Oct 2011

Sign lighting of overhead sign structures is not required.

12.1 Site Inspection

It is the responsibility of the design consultant to become familiar with existing overhead and underground facilities that may interfere with lighting pole locations. The lighting

design should also be coordinated with proposed facilities such as underground drainage

 pipes and inlets, guide rails, utility relocations, overhead sign structures, and bridge

structures.

Attempts shall be made to avoid mounting lighting poles on bridge structures unless

necessary to maintain satisfactory footcandle levels. Where necessary, locate poles asclose to pier locations as possible, the distance from the pier not to exceed one-third of 

the length between adjacent piers.

Make arrangements with the Commission for inspection of all existing power supplyfacilities that may be affected by this work. Coordinate with the local electric utility to

determine the type and location of all available electric sources.

Interchange lighting will be controlled from a central location using a photoelectric cell

and lighting contactor. Controls will utilize a manual-automatic switch and High Intensity

Discharge (HID) rated lighting contactor. Avoid locating the photoelectric cell near alight pole to avoid on-off cycling of the lighting system. Time clocks are not acceptable.

12.2 Conceptual Lighting Design (Lighting Study)

A.  Mainline Turnpike

1.  The Study shall include an evaluation of options and alternatives such as the

use of high mast lighting, conventional lighting, offset lighting, some

combination of high mast & conventional lighting, and some combination of 

high mast and offset lighting within the project limits. Note where underpasslighting may be required. Also included should be the general limits of the

 proposed lighting, as well as luminaire mounting height and wattage data

2.  Lighting warrants are not required. Full lighting shall be provided, however lighting on the mainline roadway is not required. Any spill light is considered 

incidental. In areas where ramps run parallel with the mainline, only the ramp

width is considered in the calculations.3.  To be considered in the conceptual lighting design is the construction cost

estimate, yearly energy cost comparison, 30 year operation and maintenance

costs, safety concerns, and light trespass concerns.

4.  Sample lighting design calculations should be included for each lightingscheme.

5.  Provide recommendation for best option with supporting documentation.

B.  Mon-Fayette and Southern Beltway Projects

Investigate lighting warrants to determine either full or partial lighting.

1.  Full lighting is defined as the complete lighting of the entire ramp length from

the intersection with the cross road to an area merging with the mainline 600-800 feet before (exit ramp) or after the theoretical gore (entrance ramp). This

is applicable to ramps with both toll plaza and non-toll plaza facilities. Cross

road intersections will be lighted. Cross road and mainline Turnpike are not

lighted. Only the ramp width is considered in the lighting calculations for design purposes.

2.  Partial lighting is defined as the full lighting of ramps with toll plaza facilities,

as noted in Paragraph (a) above, and the lighting of the intersections of thecross roads, and the partial lighting of the ramp/mainline gore area on the non

toll plaza facilities ramps. Cross roads and mainline Turnpike are not lighted.

Only the ramp width is considered in the lighting calculations for design

 purposes.3.  As a minimum, the Commission will provide partial lighting.

4.  Only Conventional type lighting will be considered. High mast lighting is not

acceptable. Offset lighting will be considered at Mainline Plazas only.5.  Lighting warrants will be based on the traffic counts for the roadway “design”

year.

 b.  Ramps

Ramp areas are defined as the connecting roadway between the mainline

roadway and the secondary (crossroad) roadway. Toll Plaza ramp lighting

will be continuous, beginning at a point 600-800 feet from the theoreticalgore, extending to the transition zones, and extending from the transitions

zones to the intersection or ramp system of the secondary roadway. No

 partial lighting will be considered unless directed by the Commission. The

installation of a “go ahead” light pole along the mainline will not berequired. Do not include the mainline roadway adjacent to the ramp and 

gore areas in the footcandle analysis. The target illumination level for all

ramp roadway surfaces shall be 0.60-0.90 average maintained horizontalfootcandles. Actual design average shall not be below 0.60 footcandles.

The minimum illumination level at any point on the roadway surface shall

not be lower than 0.20 footcandles. Unprotected lighting poles that are

within the clear zone will be mounted onto breakaway bases (Type S) and foundations conforming to latest AASHTO requirements. Lighting poles

that are outside the clear zone, or that are protected by guide rail or 

concrete barrier will be mounted onto non-breakaway bases (Type A) and foundations conforming to latest AASHTO requirements.

c.  Transition Zones

Transition zones are defined as the roadway between a ramp and a toll

 plaza area. Transition zones will not extend more than 400 feet from thecenterline of the tollbooths. The transition zones will be designed to

gradually transition the average maintained lighting levels from the ramp

0.60 footcandles to the toll plaza area 1.50 footcandles. All lighting polesin this area will be mounted onto non-breakaway bases and foundations

conforming to latest AASHTO requirements. Lighting circuitry in this

area will be connected to the interchange stand-by generator, where

available, on new interchange projects.

d.  Toll Plaza Areas

The toll plaza area is defined as the roadway area extending towards the

transition zone, a distance of 100 feet on either side of the toll plaza from

the toll booth centerline. The toll plaza area will be designed for 1.50average maintained horizontal footcandles. Lighting contribution from

canopy fixtures will not be considered in the lighting design analysis. All

lighting poles in this area will be mounted onto non-breakaway bases and 

foundations conforming to latest AASHTO requirements. Lightingcircuitry in this area will be connected to the interchange stand-by

generator, where available, on new interchange projects.

e.  Employee Parking Areas

Employee parking areas adjacent to the interchange building will bedesigned for 1.00 average maintained horizontal footcandles. All lighting

 poles in this area will be mounted onto non-breakaway bases and 

foundations conforming to latest AASHTO requirements. Design special pole foundations with elevated pedestals at all pole locations that may be

subject to vehicle contact within the parking lot. Pedestal foundations shall

 be a minimum of 24 inches above the parking lot surface. Lighting

circuitry in this area will be connected to the interchange stand-bygenerator, where available, on new interchange projects.

f.  Underpass Lighting

Under certain conditions, underpass lighting may be required to maintain

adequate levels of illumination. These conditions include, but are not

limited to, the overall width of the overpass and the vertical clearance beneath the overpass. If underpass lighting is required, the underpass

roadway will be designed for the same average maintained footcandle as

the roadway outside and adjacent to the underpass area. 70-watt or 100-watt high pressure sodium, wall-mounted luminaires shall be used for 

underpass lighting, when possible. If the concrete bridge abutment or pier 

cap is greater than 30 feet from the edge of traveled roadway, 70-watt or 100-watt high pressure sodium, overhead-mounted underpass luminaires

will be considered. If overhead-mounted luminaires are required, they

should be attached to the bridge structure steelwork directly over the edgeof pavement. Do not attach the luminaires to the underside of the concrete

deck. Mount bottom of luminaire flush with bottom of steelwork.

Attachment to concrete girders will require a special design. Coordinatewith the bridge design to ensure that all structure mounted lighting items

such as junction boxes, conduits and mounting brackets are included in the

 bridge design.

g.  Temporary Lighting

On existing reconstruction projects where all, or portions of, existinglighting need to be removed for roadway/toll plaza construction,

temporary lighting will be required to provide adequate lighting to

maintain operations of the toll plaza facility. Temporary lighting mayconsist of wood poles and overhead wiring.

Utilize 250 and 400 watt HPS, M-SC-II conventional (cobrahead)

luminaires on wood poles at a 35 foot luminaire mounting height.

3.  Luminaire Mounting Height

a.  Conventional Lighting

The luminaire mounting height is the height of the luminaire above thefinished pavement surface. Pole shaft lengths may vary to compensate for 

the difference in elevation between the top of the pole foundation or 

anchorage and the roadway surface. This adjustment to the pole shaft is

noted by the C-dimension as shown on the Standard Drawings and shall beindicated on the lighting plans. The standard nominal mounting height for 

conventional luminaires shall be 40 feet. Mounting heights of 35 feet and 

45 feet may be permitted if special conditions exist. Each CommissionMaintenance District operates a 65-foot bucket truck to maintain lighting

systems. The reach of the 65-foot boom limits excessive pole heights. If it

is necessary for the bucket truck to extend its boom horizontally, the 65-

foot height will be reduced accordingly. The boom will also be used to liftand remove the lighting standard. The weight of the pole may also be a

limiting factor. Verify that Commission maintenance equipment is capable

of servicing luminaires with mounting heights greater than 40 feet if higher mounting heights are required.

 b.  High Mast Lighting

•  The nominal mounting height for high mast lighting is 100-foot.Lighting poles between 80 and 120 feet may be used in the lighting

design to achieve desired results. High mast poles shall not exceed 120

feet.•  High mast lighting systems utilizing 60-foot mounting height may be

considered for extenuating circumstances. Approval by the

Commission is required.

4.  Roadway Width

Roadway Width is defined as follows:

a.  Edge of traveled pavement for all open roadways. Entire cartway (parapetto parapet) on bridge decks. Curb-to-curb for all curbed roadways.

 b. 

Although shoulders will be incidentally lighted, light levels on these areaswill not be part of roadway lighting calculations.

5.  Calculation Methods

Calculations should be submitted in a form that is legible and that can beeasily reviewed. Provide all applicable photometric curves, point-to-point

calculations, straight-line calculations, etc. Provide IES luminaire photometric

information in electronic form. Submit lighting calculations in paper form.

12-10Oct 2011

Include a CD-ROM with site-specific software files in VISUAL, version 2.0

or later format for all computer-assisted calculations. Provide all input criteria

for the software including luminaire coordinates.

When a portion or section of the highway is under analysis, it shall be

analyzed by single pole spacing as self-contained areas of analysis (asrequired in PennDOT Design Manual Part 2). While calculation of entire

ramps or roadway areas may assist the designer with layout and spacing of 

luminaires, the overall area illumination statistics will not be accepted as

meeting the Commission’s lighting criteria.

The self-contained areas of analysis shall correspond to the highway geometry

under investigation and Commission’s requirements. Each self-contained areashall be considered a flat plain with 0 foot elevation for conventional lighting

calculations. Lighting pole layout parameters shall conform to PennDOT

Design Manual Part 2, Section 5.5-A.

Interchange ramp lighting calculations and tabulations will be submitted in the

form detailed in PennDOT Design Manual Part 2, Section 5.14. Roadway

lighting point calculations will have a transverse spacing that results in aminimum of three rows of analyzed points across each lane of the roadway.

Use a longitudinal point spacing that will result in a minimum of 15 columns

of analyzed points along each lane of the roadway per luminaire spacingcycle. Points should be distributed evenly across the calculated areas and 

should be located along the edge of pavement as much as possible.

Interchange toll plaza areas, transition zones and parking lot calculations will

 be provided in sufficient detail and with enough lighting calculation points to

determine the adequacy of the lighting system. Maximum transverse and longitudinal spacing of calculation points should not exceed 10 feet.

Provide a separate calculation for each luminaire spacing cycle.

The standard light source for conventional lighting at ramp locations is high- pressure sodium. Either, high-pressure sodium or metal halide light source

may be required by the Commission at transition zones, toll plaza areas and 

employee parking lots.

For the preliminary lighting design, the average point method for single pole

spacing shall be used. The Commission utilizes the Visual lighting design program. All designers shall use this program. Other lighting design software

may be approved, but the designer would be responsible for providing the

Commission a registered copy of the software and training at no cost to the

Commission.

each of these points, considering the usable contribution from all poles in

the vicinity of each point.c.  Determine the average maintained footcandle level in each section by

adding all footcandle points in that section and dividing by the number of 

 points in the section. The result shall be between 0.60 and 0.90maintained footcandle.

d.  Determine the uniformity ratio of each road section by dividing the

average maintained footcandle level in that section by the minimumfootcandle level at any point in the section. The result shall be equal to or 

less than 4:1, average to minimum.

e.  High mast pole layout parameters shall conform to PennDOT DesignManual Part 2, Section 5.5-B.

Oct 201

C. Discharges

1.  Use the 50-year flood event as the design flood for all mainline structures.

2.  Base the design flood for other structures over waterways in accordance with theclassification of the roadway that the structure carries based on Design Manual 2

criteria, unless potential impacts to the Turnpike warrants use of the 50-year flood.3.  Include an analysis for the 100-year flood in accordance with DEP floodplain

management criteria.4.  Determine additional check floods as required.

17.3 Hydraulic Analysis

Select a hydraulic modeling method that is acceptable to the environmental permitting

agencies and perform a backwater analysis to determine the effects of the project on the

existing floodplain. Include structures, channel changes, and embankment encroachments paralleling floodplains in the same hydraulic model, but address separately in the report.

Provide hard copy analysis results from applicable computer programs, including profilesand cross-sections, as an appendix to the report. Include electronic computer program files

on floppy or compact disc bound into the report using a pocket or sleeve.

A. Modeling Method

1.  Select the hydraulic modeling method based on the type and size of the

structure and its impacts to the channel and floodplain.

2.  Use HEC-RAS for situations where floodplain topography influences the backwater analysis, including multiple culverts in a series where backwater isaffected.

a.  Construct the HEC-RAS model in accordance with the program’s users and hydraulic reference manuals.

 b.  Model the stream reach of interest and adjoining reaches when backwater 

from the adjoining reach affects the reach of interest.

c.  Include appropriate discharges for all modeled reaches.d.  Locate stream cross-sections in accordance with program guidelines and far 

enough along the reach to account for all impacts that could affect flood water 

surface elevations.e.  Extend cross-sections to a high enough elevation to contain the 100-year 

flood.

f.  Establish flow boundary conditions based on survey data or water surfaceelevations that result from downstream factors.

g.  Model replacement structures in the same manner as existing structures unless

the type of replacement warrants a different technique.

h.  Use the culvert routine to model structures under fill that generate a

headwater to depth ratio greater than 1.0.i.  Select the appropriate high and low flow analysis methods for bridge

models. j.  Disregard existing silt and sediment deposits that will be removed byhigh flow when modeling the streambed in bridge routines; transportable

deposits do not affect water surface elevations.

k.  Disregard streambed shape when modeling natural bottom structures asculverts. HEC-RAS does not consider ground points in its culvert

routine. The program models a level surface across the culvert bottom

 based on input invert elevations.

l.  Deduct depth of streambed material from overall height of opening or use blocked bottom option to establish reduced vertical height of solid 

 bottom structures that are anticipated to fill in with streambed material

and are modeled using the culvert routine.m.  Use the Generate Report option to provide a reviewable, detailed output

of the HEC-RAS model.

n.  Plot HEC-RAS cross-sections and profiles in landscape style to areasonable and consistent scale.

3.  Use HY-8 for culvert extensions and similar situations where simplified 

 backwater analysis is generally accepted. Additional analysis is necessary whenculvert extensions are a different shape, slope, size or material type using the

appropriate reference material (HEC-22, Hx5-5, etc.) to ensure related headwater 

elevations.

a.  Construct the HY-8 model in accordance with the on-screen menu.

 b.  Adjust Manning’s value to account for streambed friction for silted-in and natural bottom culverts.

B. Backwater Analysis

Perform a backwater analysis for the existing and proposed conditions to determine

the effects of the structure modifications, embankment encroachment, and channel

change on flood flow.

1.  Create an existing condition HEC-RAS model that establishes the base flood 

elevations against which the effects of the proposed condition are compared.

2.  Superimpose on the existing condition HEC-RAS model the proposed structure

modifications, associated embankment encroachments, and channel changes tocreate a proposed condition model that computes their backwater effect.

a.  Use the same stream cross-sections for both the existing and proposed conditions

to the maximum extent possible. b.  Avoid adding or deleting cross-sections in the proposed model when possible

adding, subtracting, and re-orienting cross-sections leads to questionable results.c.  When adding cross-sections is unavoidable, ensure that reach lengths are adjusted.d.  Make reach lengths for the existing and proposed models the same unless channe

changes necessitate modifying the reach length for the proposed condition. Make

the proposed reach lengths consistent with the differences resulting from thechannel change.

e.  Justify hydraulic performance of transitions due to culvert extensions with a

dissimilar shape.

f.  Maintain the modeled slope of the existing culvert for the culvert extensions unlessthere is a clear and compelling reason to break the slope. The existing slope of the

culvert is best determined by survey of the culvert roof or crown at each end.

g. 

Model a “cleaned” streambed for both the existing and proposed conditionsstreambed cleaning is not a justifiable reason for backwater decreases resulting

from the hydraulic analysis of the proposed condition.

3.  Account for the effect of any temporary facilities required for construction in an

additional HEC-RAS model.

a.  Include a temporary stream crossing when necessary to facilitateconstruction access.

 b. Model stream crossings as culverts and size the pipes and embankment

material for normal flow, or greater depending on the anticipated use of thetemporary facility, with adequate freeboard.

c.  Model cofferdams and causeways as blocked obstructions.

d. Include the existing and proposed structures in the same model where phasing will require both structures to be in place at the same time.

e.  Evaluate the temporary condition for a 2.3-year storm and include a

discussion in the risk assessment. If the backwater from a 2.3-year storm

associated with the temporary crossing is contained within the channel banks, no flowage easements will be required. If the proposed temporary

crossing causes an increase in the 2.3-year that is not contained within the

channel banks and causes additional flooding on land outside the Turnpikeright-of-way, written consent from the affected property owners allowing

this temporary flooding of their property will be required.

C. Scour Analysis

Perform a scour analysis for the recommended structure in accordance with Section

7.2 of PennDOT Design Manual 4 and the equations and guidelines provided inFHWA Hydraulic Engineering Circular No. 18, Evaluating Scour at Bridges.

Oct 2011

1.  Compute contraction scour for all natural bottom structures; compute local

scour for piers and abutments when they are subject to flood flow.  Compute scour depths as needed for setting footing depths in accordance

with PennDOT Design Manual 4 PP7.2.4.2.  Address aggradation and degradation scour based on field observations. 3.  Ignore backwater resulting from existing downstream factors, such as a

confluence with another waterway, when computing scour depths. 4.  Determine properly-sized rock for backfilling of substructure excavations

within the floodplain. 

17.4 Risk Assessment or Analysis

Include a risk assessment or analysis that addresses permanent and temporary

impacts to the natural and manmade features of the floodplain.

•  Perform a risk assessment for impacts that occur in non-sensitive rural locationsand that produce minimal changes in floodwater elevations and velocities.

•  Perform a risk analysis for impacts in sensitive urban locations that potentially

 produce significant economic damages to existing properties.

17.5 Summary Data

Provide a summary of waterway and structure data. An acceptable blank form Summary

Data Sheet form may be downloaded from the PennDOT website, www.dot.state.pa.us/hh/. 

17.6 Drawings

Attach drawings for use in obtaining the joint permit that are consistent with the permit

requirements.

A.  Provide a full size site plan that includes the following items:

1.  Layout of existing and/or proposed structures, stream channels, and embankment encroachments.

2.  Existing and proposed contours.

3.  Wetlands.

4.  Property lines and owners.5.  Location and extent of all survey/HEC-RAS cross-sections.

E.  Category F - Non-standard Project Specific Special Provisions

Specifications in this category are those that are specific to a project and either 

modify a Commission Specification (CS), a Commission Standard Special

Provision, a PennDOT Specification or do not relate to any of the above. They are

included in Section F in the spec book. No dates are shown with these SpecialProvisions.

18.2  Item Numbers 

A.  General

The PennDOT Master Items list is used as a basis for establishing item numbers

on a project. Items are arranged on the Summary Sheet, Tab sheets, and in the

Schedule of Prices in exactly the same order as they appear in the PennDOTMaster Items list. Items proceeded by a 0 or 1 indicate that all work pertaining to

that item is in accordance with PennDOT Publication 408. Items preceded by a 2

indicate that PennDOT Publication 408 has been modified by either aCommission Specification (CS) or a Commission Standard Special Provision.

Items preceded by a 3 indicate that PennDOT Publication 408 has been modified 

 by a non-standard project specific special provision. Items preceded by a 4

indicate that either a Commission Specification (CS) or a Commission Standard Special Provision has been modified by a non-standard project specific special

 provision.

In certain instances, the Commission has established standard item numbers for 

items covered by either a Commission Specification or Commission Standard 

Special Provision that do not appear in the PennDOT Items Catalog. These itemsare identified in the PTC Master Item List and/or the Standard Special Provision.

Chapter 19 – PLAN PRESENTATION

19.0 Introduction

All plan drawings are to be developed in accordance with the Pennsylvania TurnpikeCommission’s Engineering Department current CADD standards and the Design

Deliverable Scope with this Manual superseding the current CADD standards where

applicable. All other CADD standards or plan presentation details not covered by the previously noted documents shall be in accordance with PennDOT Publication 14,

Design Manual Part 3, Highway Plans Presentation.

19.1 Tips for Design Field View Presentation

A.  Show existing drainage on the proposed cross sections.B.  Show proposed drainage on the proposed cross sections.

19.2 Tips for Plan Presentation

A.  Right-of-Way lines for all state and township highway easements are not shownthrough Turnpike limited access Right-of-Way.

B.  List contract drawings on the title sheet and not in the specifications.

C.  On index maps – show Structure numbers, Mile Post, Stationing, etc.

D.  Show contours on construction plans only for special conditions.

E.  Show match lines between drawing sheets denoting adjacent sheet numbers.F.  Right-of-Way numbers and Station/Offset values for right-of-way are not shown on

construction drawings; but, they are shown on the Right-of-Way/Geometry Plan.

G.  Show item number on plan for special details that have special provisions.H.  Items are to be arranged in the tabulation and summary sheets based on the last three

(3) digits of the first grouping of four (4) digits.

I.  Typical sections do not show stationing on final plans.J.  Do not include the inlets conditions (CS-605.3) on the plan sheets.

K.  Profiles – it is not necessary to show longitudinal drainage.

L.  Graphic Scale Bar shall be used on all scaled drawings.M. For Mainline sections, provide Milepost references every tenth of a mile.

 N.  Labels for BEGINS and ENDS for pavement markings are to run with the stationing.

Do not run the BEGINS and ENDS with direction of travel.

19.3 Tips for Property Plot Plans

A.  Take areas should be subtracted from the larger of either the deed area or thecalculated deed area. If the deed area is not able to be obtained, use the calculated 

deed area. Areas to be shown in acre units to three decimal places. Square feet to be

used for areas less than 40 square feet. If the deed area is square feet, then show thetake are in both square feet and acres.

B.  Calculate and subtract legal right-of-way areas (S.R.’s, Township Roads).

C.  Take area descriptions should be based upon the project bearings except for total

takes.

Oct 2011

D.  Plots without limited access takes do not need oil, gas or surface mining note.

E.  Cut and Fill lines should not be screened on property plot drawings.

F.  Proposed and existing roadway pavement lines should be shown.G.  Existing PTC limited access right-of-way can be shown as an adverse or exception, as

applicable.

H.  Show adverse and exception areas, but do not show the bearings and distances on

these areas.I.  Change Pre-Final date in Property Plot block with each submission.

J.  Show all features close to the right-of-way that may experience damage (fences,

mailboxes, lights, statues, swings, shrubs, trees, etc.) and features (buildings, septicsystems, wells, etc.) affecting the property assessment.

K.  Show details of existing driveways and proposed driveways.

L.  Proposed utility work should be shown.M. Remove any hatching where it obscures important topographic features.

 N.  Required Right-of-Way breaks should be set with whole numbers (+00.00, +05.00,

etc.) when ever possible.O.  Scaled offset values should be rounded to the nearest foot.

P.   New offset values should be expressed to 2 decimal places.Q.  With the exception of “total takes”, avoid creating new right-of-way corners /

changes in direction upon existing property lines. Establish and define new right-of-

way corners by station (plusses) and offset distances from baselines. Creating a new

right-of-way corner / change in direction on an existing property line could require

record research and field recovery of evidence to re-establish that property line.R.  If possible, try to avoid creating any new right-of-way or easement corners radial to

spiraled baselines. In spirals, try to make “required” Right-of-Way lines straight lines

originating and ending at points perpendicular to tangents and radial to simple curves.S.  A submission of the computer print out denoting all courses and error of closure is to

 be submitted with the original deed.

T.  Legal descriptions should always be in a clock-wise direction.U.  Prime consultants should make all right-of-way submissions.

V.  No abandonment or vacations should be shown without approval of legal department.

W. The use of abbreviations should be avoided.

X.  Limits of the 100 year flood plain should be shown on the plot when it is in thevicinity of the required take area.

19.4 Tips for Cross Section Presentation

A.  Should be presented using PennDOT Design Manual Part 3 and the following:

B.  Label Superelevation rates on each section when in transition or pick a point in the

 pavement and state the elevation difference from the profile grade.C.  Show the following on the cross sections: guide rail with out the start/stop notes,

right-of-way lines, perpetual easements, drainage inserts and super elevation.D.  Label the Legal Right-of-Way Lines and Perpetual Easements (i.e. Drainage

Easements, Utility Easements)

E.  Ensure that the Graphic Grade (GG) elevations are labeled where applicable.

F.  Clearly label the Edge of Barrier elevations at the Concrete Glare Screen when thereveal varies throughout the Graphic Grade transition areas.

G.  Provide lateral offsets from the Survey and Construction Baseline to objects that vary with

respect to the Baseline. (i.e. retaining walls, 50’ rounding when SE >6%)

H.  Provide lateral offsets and elevations for pavement breakpoints that are not clearlydefined either on the plans or typical sections. (Examples could include, but are not

limited to, interchange gore locations and mainline/auxiliary lane junctions)

I.  Label the invert elevations of parallel ditches along with the associated Class 2

ExcavationJ.  Provide Earthwork Quantities (Cut/fill) by the overall stage and not each phase in

each stage.

K.  Cross section grids are generally acceptable as generated by the design software and only needs to be shown in the area of the cross section.

L.  Label inlet conditions along with the required drainage data.

M. Provide benching quantities for earthwork. rock and embankment.

Dear  Name:

The Pennsylvania Turnpike Commission (PTC) has initiated preliminary design for the

reconstruction and widening of the Pennsylvania Turnpike from Milepost xx, approximately xx miles

east of  xxxx Interchange, to Milepost xx, approximately xx mile east of  xxxx Interchange, in xxxx County. The municipalities that are affected include xxxx Townships.

The PTC will conduct a study as one of the first tasks to determine the impacts to utilities, localroad and stream crossings, and properties adjacent to the Turnpike due to the roadway widening and will

investigate and evaluate impacts from flattening existing substandard horizontal curves.

In addition, this project will require the replacement of bridge structures carrying local traffic

over or under the Turnpike and the potential elimination of a few of these low traffic volume structures

during the study task will be evaluated. The PTC will investigate the distribution of local road trafficduring the construction activities at each bridge structure and will evaluate the need for separate

construction contracts in order to utilize effective detour routes where detours are required. Consultant name is under contract with the Commission to perform the study task as well as the design for the project. They may be contacting you in the near future for pertinent traffic or other information. Your 

cooperation and input will be greatly appreciated.

At the completion of the widening study task (six to eight months), the PTC will schedule a public officials meeting to discuss our findings and to hear your concerns. Should you have any

Dear  Name:

The Pennsylvania Turnpike Commission has initiated the design for the total reconstruction of 

the Pennsylvania Turnpike mainline from Milepost xx, approximately xxxx miles east of  xxxx Interchange, to Milepost xx, approximately xx miles east of  xxxx Interchange. Consultant   Name will

 perform the design for this reconstruction project. Due to the coordination that will be required betweenthe Department and the Commission for traffic control, detour routes, highway occupancy permits, and 

other issues, we are writing to inform you of this project.

The total reconstruction project will include the removal of the existing bituminous and concrete

 pavement and replacement with a full-depth bituminous pavement, the replacement of the drainage, and the widening of the median from the existing 10-foot width to a 46-foot width, if possible. We are

currently in the Study Phase of this project to determine if a 46-foot width median is feasible, and, if not

what widths can be obtained.

The additional median width will require replacement or possible elimination of overhead 

 bridges and replacement or widening of the mainline Turnpike bridges to accommodate the proposed typical section. The Commission has identified the replacement or elimination of the following bridgesas key components within this project.

Currently, it is anticipated that the study and design work for this project will extend from

 ___________ _________ through __________ ________. It is also anticipated that construction for themainline Turnpike total reconstruction project will extend from the 200__ through the 200___ 

construction seasons. However, some of the bridge replacements or possible eliminations may occur in

separate contracts in which the construction could be as early as the 200___ construction season. This

would insure that two bridge crossings in the same vicinity are not being detoured at the same time.

As the design efforts for this project progress, we will continue to keep you informed of any

issues with regard to this project that require Department attention. We currently anticipate scheduling a preliminary coordination meeting for this project between the Department and the Commission at the

end of the study phase/beginning of the design phase, which will be in approximately six months. We

will contact you closer to that time to set up a meeting date, time, and location. Should you have anyquestions concerning this project, please do not hesitate to contact me at (717)939-9551, extension xxxx,

Sound Barr ier Meeting 

Dear Property Owner:

The Turnpike Commission is currently performing the engineering design work for the

reconstruction of the Carlisle Interchange on the inside of the toll booths. As part of the design effortsfor this project the Turnpike Commission conducted noise analysis studies throughout the project limits.

The noise analysis studies indicated the area along the Eastbound Exit Ramp, south of the Turnpike, as a

 potential sound barrier location.

Since your property is adjacent to the potential sound barrier, the Turnpike Commission seeks

your opinion on whether or not the proposed sound barrier should be constructed at this location. If 

there is agreement among property owners in the adjacent residential neighborhood to proceed with thissound barrier construction, then the Turnpike Commission seeks your opinion on the appearance of the

 proposed sound barrier facing the residential neighborhood.

A meeting is scheduled for  Date from XX:XX XM to XX:XX XM at the Location, Address to

discuss the proposed sound barrier for the above referenced project. In order to have an influence on this

 process, you must be present at this meeting.

During this meeting, you will be shown the location and height of the proposed sound barrier,

along with texture and color options. A consensus needs to be reached on the desire for a sound barrier,

and if a sound barrier is desired, a consensus also needs to be reached on the texture and color of thesound barrier on the side facing the residential neighborhood.

Please contact me at Telephone Number to let me know if you are able to attend this importantmeeting. Your cooperation in this matter is appreciated.

Sincerely,
