6.2 SALIENT FEATURES OF PROPOSED ROUTE

As can be seen from the above description, the entire route of the pipeline (except initial 898.51 meters) runs parallel

to National Highways.

There is no dedicated ROU for pipeline laying, except the section mentioned below:

• ROU : Pipeline ROU has been acquired, adjacent to National Highway, for pipeline route section from TP-

81 (Ch. 10.323 km) to TP-92 (Ch. 12.744).

Other than the above section, the entire length of pipeline route runs parallel to National Highway (NH-58 and NH-

72). The following points needs to be considered for these portions of the pipeline route:

• The entire route runs along the National Highways (NH-58 and NH-72).

• There is no dedicated ROU for the pipeline,

• The Pipeline shall be laid in the corridor provided by NH authorities, on the edge / shoulder of the National

Highways.

• The width of this corridor is expected to be approximately 500mm to 1000 mm, and may vary further at

various locations.

Additionally, the following points need to be noted:

• Both the Highways (NH-58 and NH-72) are busy National Highways with traffic.

• At most locations, there is not much space available on the side of the National highways, and the pipeline

shall be laid in a small corridor on the edge of the Highway

• Inside Haridwar city, the National highway passes through very congested locations, and there is very

limited space available for pipeline laying and construction works.

• At many locations, especially in city areas, there is no space available on the sides of NH and the

constructed area / structures are touching the edge of the road boundary.

• Additionally, at various locations, the area on the sides of NH is densely populated,

• At all such locations, the contractor will have to carry out pipeline laying and construction works

considering the restricted width of corridor available for works.

• The pipeline laying thus needs to be done very carefully all along the route, specially in all such sections, in

view of limited availability of space, and in view of presence of existing buildings /structures and

installations.

6.3 RECOMMENDATIONS FOR PIPELINE LAYING

In view of the above observations, the following recommendations are made, for pipeline laying along the proposed

route:

(a) The depth of top of pipe (Cover from Natural Ground level) is recommended to be min. 1.2 m, for the entire

length of the pipeline route.

Page 31 of 130


D 11039

001


(b) Installation of Concrete Slabs on top of pipeline, is recommended for below listed stretches due to high

population concentration during Kumbh festival, concrete slabs should be provided to protect the pipeline

from possible Third Party intrusion damages. The design of concrete slabs shall be as per project standard

drawing :

♦ CH : 0.898 Kms to 2.013 Kms ( 1.115 Kms stretch)



♦ CH : 13.283 to 14.000 Kms ( 0.717 Km stretch)

Additionally, the following requirements shall be adhered to, for the laying of Pipelines:

(c) 50 km Mainline from Haridwar to Dehradun :

Although the Pipeline Route falls in location class 1, 2, 3 & 4, considering densely populated urban areas,

and future growth potential, location class 3 & 4 only shall be considered for entire pipeline, as described

below :

• Location Class -3 shall be considered for :

o all Locations falling in Protected Forest Area

o all major HDD crossings

(as future population growth in these areas is not likely).

• Location Class-4 shall be used for:

o Pipeline laying in areas falling under location class 1, 2, 3 and 4 (except the two sections listed

above)

o All Railway crossings, and pipeline laid within the ‘risk radius’ on both sides of Railway

Crossings,

o HDD crossings in densely populated areas, and areas falling within railway risk radius

o All station piping

(d) 4 km Spurline from Tap Off (SV-2) to Rishikesh :

The entire pipeline route from proposed SV-2 / Tap Off Station upto Rishikesh is in class-4. Accordingly,

the entire pipeline shall be considered as Location Class-4, including HDDs and Stations.

The contractor shall follow all the above requirements stringently, for the entire pipeline laying activity including

associated station works, and all necessary precautions, and safety measures, required for safe execution of the project

shall be taken by the contractor.

6.6 PIPELINE LAYING METHODOLOGY

Considering the route profile, terrain, location of pipeline laying corridor adjacent & parallel to the National highways

for the most part and densely populated clusters adjacent to the route at many locations, the following three (3)

methodologies are proposed for pipeline laying along the proposed route :

1. Laying by HDD only: All Major crossing, including all River Crossings, shall be done by HDD only. Additionally

there are clusters along the route, especially in city & populated areas, which are very congested and there are

existing buildings / structures touching the boundary of NH. Laying by open cut is not feasible at such locations

and pipeline laying and crossing in such clusters is also proposed to be carried out by HDD methodology, for ease

of execution and for ensuring future safety of the pipeline.

2. Laying by (Open Cut) / with Option of laying by HDD : There are clusters along the route, in city & populated

areas, which have existing buildings / structures adjacent / close to the boundary of NH. Laying by open cut is

feasible in most parts of such locations, however there may be some small stretches / clusters where laying by

open cut may not be feasible. In such small sections and clusters the pipeline laying and crossing may be carried

out by HDD methodology, considering ease of execution and for ensuring future safety of the pipeline.

The sections / clusters which are to be done by HDD shall be determined by the contractor based on actual site

conditions and requirements. The design and engineering of HDD including finalisation of profile, shall be done

by the contractor, based on site requirements. The clusters where HDD is opted by the contractor, shall be done

without any cost and time implication to the client.

Page 35 of 130


D 11039

001


Additionally, Concrete Slabs shall be provided for protection of pipeline from possible third party damage, in

stretches where Kumbh Mela takes place, as listed in Section 6.3.

3. Laying by (Open Cut) only : For all other sections of the pipeline route, where pipeline laying by open cut

methodology is feasible, shall be done by open cut method. The exact methodology shall be finalised by contractor

based on site conditions. Where required, due to restricted space / site conditions, the trenching / laying may need

to be done manually. The same shall be determined by the contractor based on site requirements.

All required precautions shall be taken to ensure safety and integrity of the existing installations and structures in the

vicinity of the proposed pipeline route, during and after construction. All necessary precautions shall be taken into

account during residual engineering, planning, and execution of pipeline laying and construction works, for working

in the vicinity of National Highways with active traffic, and populated areas.

Additionally, all the site specific recommendations and requirements listed in sections 6.3 to 6.6 above shall be adhered

to, during complete project executing. In all the sections where HDD methodology is followed, the requirements listed

in Section 8.5, for HDD crossings, shall be followed.

Where HDD is required, the Contractor shall be responsible for complete design of HDD Crossing including

performance of requisite surveys, performing of calculations, profiling, pull load calculations and hook-up of the

crossing pipe on upstream and downstream. Any additional land required for execution of HDD shall be in the firm

scope of contractor.

The change of Crossing Methodology especially for Waterbody/canal crossing (from open-cut to HDD) is subject to

approval from Owner/PMC and does not entitle contractor for claiming any additional time and cost implications.

The Contractor is deemed to have made due provisions in his bid for all such works.

a. Foreign Pipeline Crossing

In case any existing pipeline needs to be crossed, the new pipeline shall be laid at least 500 mm below such

existing pipeline, and a physical barrier in the form of 80 mm thick concrete slab shall be provided. The existing

pipeline shall be properly supported during and after the construction.

b. Over Head Power Transmission Line Crossing

per approved Crossing methodology and shall be the scope of contractor.

d. The details shown in Alignment Sheets and crossing lists, such as Crossing methodology, Overall Crossing

length, quantity of special measures are indicative. However, contractor is required to carry out detailed survey,

obtain local information, verify geotechnical/hydrological soundings and submit the working drawing based on

detailed engineering before the start of crossing execution.

e. Contractor shall note that the “Limits of Crossings” shall be as per the crossing width finalized after detailed

survey by Contractor and as approved by the statutory authorities/Owner/PMC. The “Limits of Crossings” shall

broadly include the “Width of RoW of the facility to be crossed + Installation Allowances + any additional

length as suggested by the authorities”. Execution of crossings within the approved “Limits of Crossings” will

constitute firm Scope of Work of Contractor.

f. Pre-Hydrotesting/ Post-Hydrotesting of pipeline section as per bid specification for major

River/Waterway/Canal Crossing and all Cased Crossing shall be in scope of contractor.

g. Since the crossing activities are to be started immediately, the acquisition of Land/ Approach if required to

crossing locations and additional working strip to be acquired by contractor without any extra time and cost

8.1 CROSSING METHODOLOGY

All major crossings like Highways, Railways, Lined Canals and MDR / ODR shall be laid by Boring wherever

imposed by concerned authority.

However, in this project, since the pipeline runs along the edge of National Highway, there are no NH, SH or

MDR/ODR Crossings. Hence crossing by Boring & casing may not be required. Other Road crossings shall be done

by open cut with Casing installation or Open Cut with continuous Concrete Slab installation over the pipe for the

crossing length.

For this project, at many locations the crossings shall be done by HDD, as per site requirements. The actual

methodology for crossing shall be finalized by contractor based on site requirements.

At all crossings where Carrier / Casing pipe is installed by using Boring & Casing method, a separate 6” Casing

Pipe (API 5L Grade B, 6.4 mm thk, epoxy coated, 500-micron thick), shall be installed, for housing 2 nos. of 2”

HDPE ducts (with main OFC laid inside one of the HDPE ducts and if the length is greater than 500 m then in that

case OFC shall also be laid in the spare duct.). The 6” Casing pipe shall be installed through the same bore by Bundle

pulling as shown in the standard drawings.

For all HDD crossings, Carrier pipe along with 6” pipe consists of 2 Nos. 2” HDPE ducts (with main OFC cable

laid inside one HDPE duct) shall be bundled along with the Carrier pipe and shall be installed by bundle pulling

method.

The Wall Thickness of Pipes to be used at all the crossings shall be as per Class 3 and Class 4 only.

8. Drain Crossing – Chainage 23.125 to Ch 23.201 kms.

9. Railway Crossing @ Ch. 42.986 kms.

The Chainage given above for HDD crossings are tentative. The actual starting and end points and profile

of HDD, shall be finalised by the contractor based on actual site requirements. Some of the stretches may

require multiple HDDs due to long spans. The same shall be finalised by the contractor based on site

conditions.

� Boring + Casing (B+C) / HDD along the Pipeline Route:

No crossing is proposed by Boring and Casing method for the Pipeline.

Page 50 of 130


D 11039

001


� By Open cut / HDD method (approx. 8 kms length) – Proposed method for laying / crossing shall be by

Open Cut, however the contractor may opt for laying / crossing by HDD, depending on site conditions /

requirement, and permissions obtained from concerned Authorities.

Section B: Spurline (SV2 cum Tap Off Station to Rishikesh – 8” x 3.83 KM Pipeline)

� HDD Crossings (Approx. 400 meters straight line length) along the Pipeline Route:

1. River Crossing (Bangla Rao River) at TP 4 (Ch. 1.228 kms).

2. Railway Crossing at TP 6 @ Ch. 1.446 kms.

(Both Chainage from TOP / SV-2 station.).

� Open Cut (Approx. 3.43 kms straight line length) : The Proposed method for laying the pipeline shall be

by Open Cut. Crossing methodology shall be finalized by Contractor based on site requirements.

Note : The above crossing methodology are tentative. The actual crossing methodology shall be finalized by

contractor based on actual site conditions and requirements and shall be firmed up based on Execution

methodology proposed by Pipe laying Contractor, approval by Client and permissions obtained from the

concerned Authorities.

8.4 RAILWAY CROSSINGS

Rail crossing shall comply with the requirements of API RP 1102 and Indian Railway Authorities recommended

guidelines (Report No. BS-105 and Addendum Slip-4 and 5).

For this project all the Railway Crossings are proposed to be installed by HDD Methodology.

However, if based on site conditions, any crossing is required to be done by Boring & Casing Methodology, then

the requirements as listed in Pipeline Design Basis shall be followed.

8.5 HIGHWAY CROSSINGS

In this project, since the pipeline runs along the edge of National Highway, there are no NH, SH or MDR/ODR

Crossings. Hence crossing by Boring & casing may not be required.

Most of the crossings along the pipeline are proposed to be carried out by HDD or Open Cut Methodology. (Refer

Alignment Sheets / Line Pipe MTO for further details).

However, in case crossing by Boring & Casing is required at any road / lined canal crossing, then the requirements

as listed in Pipeline Design Basis shall be followed.

8.6 RIVER / CANAL / CHANNEL CROSSINGS

Major water crossings shall be installed by Horizontal Directional Drilling (HDD) method. Minor water crossings

shall be installed by open cut or boring methods. The banks shall be protected by using gravel and boulders filled

embankment mattresses of galvanized iron wire to be laid over the backfilled, compacted and graded banks.

The protection of the banks shall be carried out across the ROU width plus three meters on either side of ROU or

actual distributed bank during construction whichever is higher. All lined canal/drains/nala will be restored to the

original condition.

Crossing by HDD shall be considered, where the following criteria is met:

• At all major perennial rivers, requiring trenchless crossings

• All rivers where discharge rate is expected to be high, leading to high scour depth

• At major lined canals, requiring trenchless crossing, and

Page 51 of 130

001


• Where adequate space is available on both sides of the crossing, for carrying out the HDD.

Based on the above points, and in addition, the information received during site visit, all major River / Canal /

Waterbody crossings of proposed Haridwar-Rishikesh-Dehradun Pipeline (HRDPL), are proposed to be carried out

by HDD method.

The Major HDD crossings shall be done by a separate HDD Contractor, as per details provided in Section 3.2.

All the remaining HDD crossings along the pipeline route, shall be in Pipeline laying contractors scope. For a

tentative list of HDD crossings to be executed by pipeline laying contractor, refer section 8.3.

Other smaller water bodies likes small drains and nalas can be crossed by Open cut / other suitable measures based

on actual site conditions & requirements. In case, HDD is found to be more suitable alternative for any of the Canals

/ Channels, the same shall be finalized by pipe laying contractor, based on actual site conditions, in agreement with

the Client.

8.7 HDD CROSSINGS ALONG THE PROPOSED PIPELINE ROUTES

Many HDD crossings are expected along both the proposed pipeline Laying sections. Most of the rivers / canals /

major waterbodies are proposed to be crossed by HDD. In addition to the requirements given elsewhere in this

document for HDD crossings, the following shall be considered for all the HDD crossings, carried out as part of this

project :

a. The exact location, length and starting & end points of the HDD crossings shall be determined based on

actual site conditions, and availability of space and permissions for carrying out HDD operation, and ease

of installation and movement of required equipment.

b. The sections where major construction constraints are likely, may also be considered to be crossed by HDD.

c. The no. and locations of HDD crossings shall be decided based on site conditions and requirements,

availability of adequate space for carrying out the operation, movement and installation of equipment, and

ease of hooking up of upstream and downstream pipeline sections.

d. The depth, routing and exact profile of the HDD shall be finalized based on site conditions and actual site

requirements.

e. Upstream and downstream pipeline sections shall be hooked-up with HDD sections, ensuring a smooth

pipeline profile, for ensuring that all pipeline stresses are within design limits.

f. Adequate protection against earth/vehicular loads in form of concrete slabs etc. and adequate anti-buoyancy

measures like concrete-coating or saddle bags etc. shall be provided for adjacent pipeline sections, wherever

required, as per site requirements.

g. All HDD crossings shall be planned and designed very carefully, considering site conditions, existing

constraints, soft soil, high water table and presence of operational pipelines in the existing Corridor. Where

required, additional working ROU for carrying out the HDD shall be arranged.

Page 52 of 130


D 11039

001


h. The planning and design shall ensure safe operation, construction and installation of pipeline, without

affecting the existing pipelines in the Corridor, existing structures and installations, and water bodies.

i. In view of the above, the HDD operations, including design, engineering, execution and testing shall be

performed by a specialist HDD Contractor, with adequate experience and proven track record of similar

operations.

j. Design and engineering of HDD operation shall also ensure that no seepage of bentonite takes place from

the HDD into the adjoining soil / fields / waterbodies etc. In case, any seepage happens, the compensation

for the same shall be done by the contractor.

The Design of all HDD operations, including design of all materials, all engineering calculations, execution,

installation and testing etc. shall be carried out in full compliance to all applicable codes and standards, statutory

requirements and in line with project specifications and requirements. Best practices from the industry shall be

considered and followed where deemed suitable.

8.8 ANTI-BUOYANCY REQUIREMENTS

As most of the major waterbody crossings, including all river crossings in this project, shall be done by HDD, the

requirement of Anti-Buoyancy shall not be applicable for most crossings.

However, if anti-buoyancy measures are required, for any location as per site conditions, then the following shall be

considered:

Concrete weight coating will be used over and above Pipe External Coating in areas prone to flooding, area with

waterlogging & marshy soil, and at water body crossings and other areas requiring anti-buoyancy measures.

Use of Geo-Textile Bags may be considered where concrete coating is not possible due to site conditions, However

the preferred method of providing anti-buoyancy shall be Continuous Concrete Coating. Where geo-Textile bags

are used, the same shall be selected to provide anti-buoyancy equivalent to the required concrete coating thickness,

as given in table below.

For Rocky River (if any) concrete coating with gabion arrangement, shall be provided.

Based on Buoyancy calculations carried out for the Pipeline, the Concrete Coating thicknesses, to be used for 8” NB

x 50.000 kms long Main Pipe Line and 8” NB x 3.830 kms long Spur Line to Rishikesh, from Haridwar to Dehradun,

shall be as below:
