BOARD OF EDUCATION OF HOWARD COUNTY MEETING AGENDA ITEM

TITLE: New Middle School #20 Construction Document Report DATE: November 15, 2012

PRESENTER(S): Bruce Gist, Director, School Construction Michael Lahowin, Principal in Charge, TCA Architects OVERVIEW: New Middle School #20, which will be located on the Oxford Square school site, will be an adaptation of the prototype middle school design. This prototype, based on the General Education Specifications for New Howard County Middle Schools, dated June 1994, is designed to accommodate a population of 662 students in Grades 6–8, plus 40 full-time equivalent special education students, for a total of 702 students and is the fifth iteration of this design. Since the design development phase, additional refinements have been made as a result of continued meetings with the Howard County Public School System’s staff, local code authorities, and the site developer. These refinements include: the use of polished concrete in corridors and the cafeteria, the reconfiguration of the service area for additional mechanical/electrical equipment, reconfigured custodial toilet rooms per revised ADA codes and additional skylights in classrooms for more natural daylight. Due to the unique location of the building and the concerns that have been raised, the appendix now includes an emergency plan summary. Energy efficiency has remained a primary driver of this project’s design. This project will utilize the United States Green Building Council LEED for Schools version 2009 and is intended to achieve a LEED Silver certification.

RECOMMENDATION/FUTURE DIRECTION: It is recommended that the construction document report for New Middle School #20 be approved. Submitted by:

Project DescriptionMiddle School #20 is to be located on a 20.21 acre site within the planned community of Oxford Square in Hanover and will be an adaptation of the current prototype middle school design. The prototype middle school plan is a two-story building designed to accommodate a population which includes 662 students in Grades 6 thru 8, plus 40 full-time equivalent special education students, for a total of 702 students. The “Space Analysis” section of this report contains a complete listing, program size, and actual size of every space included in this middle school design. It is the intent that the design and construction of this new middle school achieve a LEED

(Leadership in Energy and Environmental Design) ‘Silver’ designation making this facility yet another ‘Green’ school for the Howard County Public School System. The 2009 version of ‘LEED for Schools’ released by the U.S. Green Building Council (USGBC) will provide the necessary goals and requirements to obtain LEED Certification.(See page 7 for Sustainable ‘Green’ Design Goals.)

Continuation of the School Design Process This Construction Document Report is intended to explain and illustrate those aspects of the Middle School #20 design which have changed since the Design Development Report.

The planning process for Middle School #20, was described in detail in the schematic design report submitted to the Board of Education (BOE) and approved on February 23, 2012.

Following approval of the schematic design, a formal schematic design submittal was sent to the Maryland State Department of Education (MSDE) and later approved by them for continuation into the design development phase.

During the design development phase, the plan had undergone some minor refinements; however, the basic design remained the same with the primary effort during the design development phase being the continued refinement and development of all spaces within the school.

Following the Board’s approval of the design development report on July 12, 2012, a design submittal was sent to MSDE and later approved for continuation into the last phase of the design process, the construction document phase.

While the proposed site and floor plans in this report are very similar to those in the design development report, much of the recent work entails the development of the ‘blueprints’ from which the school will be constructed. Much of the detailing during this phase occurs above the ceilings, in the walls, and on the roof incorporating all of the mechanical, electrical, and structural elements necessary to turn this design into a buildable set of documents.

Noteworthy refinements to the project since design development approval are noted below:

•! The list of design development phase participants on page 4 has been updated to include all ! participants involved in the construction document phase.•! The ‘Project Facts’ and ‘Project Schedule’ on page 6 have been updated to include the latest building ! square footage and project dates.• The LEED scorecard on page 7 has been updated to indicate 54 anticipated credits, two more credits

than were indicated in the design development report.•! Construction document phase site plan refinements have been noted on page 11.•! Construction document phase floor plan refinements are identified on pages 13 and 14.•! The ‘Space Analysis’ on page 20 now includes construction document phase square footages.• The ‘Cost Estimate’ on page 25 has been updated by the Construction Manager for this phase.• An ‘Emergency Plan’ has been added as an Appendix to address safety concerns for this site.

Sustainable ʻGreenʼ Design GoalsIt is the intent that the design and construction of the new middle school achieve a LEED (Leadership in Energy and Environmental Design) Silver certification, making this facility a ‘Green’ school.

Simply stated, a ‘Green’ school is a building designed to conserve energy, water, and materials, thus reducing negative impacts on human health and the environment. A ‘Green’ learning environment provides natural daylight, enhanced classroom acoustics, improved indoor air quality, thermal comfort, and opportunities to integrate green features into the school's curriculum.

In order to measure and compare how ‘Green’ a building is, the U.S. Green Building Council (USGBC), founded in 1993, has developed industry standards with design and construction rating systems and guidelines for many different building types.

One such rating system is the USGBC 2009 Edition of “LEED for SCHOOLS” to which the design and construction of Middle School #20 will closely adhere. Final LEED certification levels are based on the number of credit points obtained in the “LEED for SCHOOLS” rating system. The four levels of certification from lowest to highest are: Certified, Silver, Gold, and Platinum.

We have included an ‘in progress’ LEED scorecard below which summarizes the credits most likely obtainable at this time. As the project continues to evolve, new credits may be possible while others may become increasingly difficult to engineer or too costly to provide. At this time we have identified 54 likely credits (with an additional ’8 possible credits’) allowing for the loss of some and still complying with the goal of a LEED ‘Silver’ Building.

DEVELOPMENT

SITE

Site Context !! ! ! ! ! !The middle school’s 20.21 acre site is located in the planned community of Oxford Square. Oxford Square is comprised of 111 acres, 33 of which are set aside for open space with the remainder being developed. There will be two separate entrance roads into Oxford Square from Coca Cola Drive, as indicated on the lower right corner of the graphic above.

Oxford Square will contain high-density residential housing, office buildings containing first floor retail and dining establishments, a community center and town meeting hall. Construction has yet to begin in Oxford Square but we have been told that ‘Phase 1’ will begin in 2013. During this phase, the developer will extend a road and public utilities to the school site from Coca Cola Drive.

The entire community, including the school site, is zoned TOD [Transit Oriented Development], therefore, all new construction within Oxford Square is required to comply with the ‘Route 1 Design Manual’ as well as Howard County’s ‘Green Neighborhood requirements’.

Refer to the next page for a more detailed description of the middle school site development.

Proposed Site Plan NotesKey features of the proposed site plan are listed below and identified by circled numbers on the following page.

1.! School bus parking for 17 busses. The bus driveway is separate from the parent drop-off driveway to ! reduce vehicular congestion on site.

2.! To provide as much car parking on site as possible, 119 parking spaces have been provided among four ! areas on the site.

3.! Parent drop-off and pick-up area adjacent to the main entrance with an ample queuing area to ! eliminate interference with the main parking lot.

4.! Service drive with emergency vehicle access to the paved play area and four staff parking spaces.

5.! Paved play area adjacent to gymnasium and cafetorium.

6.! Master planned area for future portable classrooms, if needed.

7.! Locations for stormwater management bio-retention facilities.

8.! Potential location for future outdoor classroom area.

9.! Playfields have been located adjacent to the gymnasium, cafetorium, and locker rooms, such that ! students will not have to cross vehicular roads or driveways to access.

Construction Document Phase Site Plan RefinementsThe refinements identified by letters in hexagons on the following page are the most noticeable changes since the design development phase.

A.! Added a temporary access road to allow access to the site from Coca Cola Drive during construction.

B.! Added a school marquis site sign on a masonry base.

C. Reconfigured the service area to enlarge the mechanical equipment enclosure for an additional generator and to ensure that dumpsters are at least 15 feet from the building.

D. ! Added a six foot high fence along the perimeter of the school’s property to control how pedestrian ! traffic enters and leaves the school site. The fence was recommended during a meeting where ! HCPSS staff, the Police department, Fire and Rescue department and the Office of Emergency ! Management routinely analyze school sites for potential safety hazards. See the Appendix of this ! report for the Emergency Plan that was generated as a result of the meeting.

Floor Plan NarrativeIn addition to the basic features of the layout listed on page 12, Middle School #20 will maintain the following spatial relationships developed for the original prototype design:

Access and Circulation

! Entrances

The main entrances are clearly marked for visitors by both their location and by the architectural significance of the projecting main stairwell.

Entrances have been arranged to distribute student traffic during arrival and departure times, to meet code egress requirements, and to permit easy access to the gym and cafeteria for after-hours activities. Particular attention has been paid to providing an adequate number of doors in the heavily populated classroom areas for dismissal time.

! Corridor Arrangement

A conscious effort was made to develop a corridor pattern which is clear-cut in its arrangement and easy to supervise. Stairs have been located at the four corners of the two-story wing. As noted, an elevator has been provided very close to the main entrance for the use of handicapped persons and for the easy movement of furniture and equipment.

The main interior stair at the front of the building is next to the main entrances and is immediately adjacent to the administrative area.

Student Lockers have been located along corridor walls throughout the classroom areas in response to a decision by the original planning committee that concentrated areas (pods) of lockers be avoided. Lockers have been located on just one side of corridors wherever possible to minimize congestion.

Student Restrooms are located on both floors near stairways in all three grade level areas and adjacent to the cafeteria and gymnasium entrances. The cafeteria/gymnasium lobby restrooms are also intended to be used during after-hours activities. Teachers' toilets have been located on both floors of the classroom wing and adjacent to the staff lounge.

The administrative area has a central location adjacent to the main entrance with a view of the parent drop-off area. This area is adjacent to the health suite and to the staff lounge and workroom. Both the health suite and the staff lounge have separate entrances from main corridors. The teachers' mail boxes, which will be in the workroom, can be conveniently serviced from the administrative area. Proximity to the cafeteria was also a consideration in the location of the staff lounge.

A volunteer/community room has been placed in a centralized location convenient to the front entrances.

The guidance suite is located in an easy-to-reach location, convenient to the office area, yet with a distinct identity.

Classrooms are located in the two-story portion of the school and arranged so that each grade level has its own distinct area. Most classrooms are located on exterior walls with windows.

As noted, science laboratories have been placed on both levels convenient to all three grade levels. Four of the five labs are adjacent to prep rooms and project/seminar rooms.


Floor Plan Narrative (continued)

Teacher planning rooms, special education classrooms, seminar rooms, and storage rooms have been distributed in the two-story classroom wing.

A related services therapy room, special education conference room, and a handicapped accessible toilet have been located on the first floor of the classroom area.

The media center is the symbolic, as well as the actual center of the school. It is located on the first floor in the middle of the classroom area and is visible from the second floor corridors above. Natural daylight from above brightens this dramatic two-story high space and the rooms surrounding it on both floors. The media center can be entered from all three adjacent corridors to encourage student use.

The computer lab and technology resource room can be entered and monitored from the media center, to which they have a strong connection. Both rooms can also be entered from the adjacent corridor.

The gifted and talented resource room has a central location in the second floor classroom area overlooking the media center.

The art classroom and the health classroom have been located on the first floor, near other related-arts spaces and are easily reached from all classroom areas. Both of these rooms are located on an exterior wall with windows.

The world language classroom has been placed in the center of the second floor classroom area.

The technology education rooms, home economics classroom, music suite, and recreation and parks suite have been located on the first floor away from the quiet two story classroom wing, yet are easy to access both during the school day and for after hours use.

The gymnasium has been located so that it can be entered from the classroom side of the school or from a lobby which also serves the cafeteria entrance. Direct access has been provided from the gym to the outdoor paved play area and to the playfields. The gym and the adjoining activity room have been placed for easy, but controlled, access during after-hours activities. Locker rooms are designed to be entered from inside the gymnasium for visual control by physical education teachers and also to have direct access to the outside.

The cafeteria has been located for easy access by after-hours users and in close proximity to the music rooms for use of the stage. For after-lunch recess there is direct access to the outdoor paved play area and there is convenient access to the gymnasium and to restrooms. It was important to the original planning committee that there be visibility from the cafeteria to the paved play area to help with lunch time supervision. Kitchen serving lines are entered from inside the cafeteria and there is convenient access to the service area for trash removal. An operable wall has been provided at the front of the stage to permit use of this area as a teaching station during lunch periods. A ramp has been provided for handicapped access to the stage.

The kitchen has a full-preparation arrangement and is convenient to the service area for deliveries and trash removal.

The custodial areas are placed on a main corridor near the service entrance and adjacent to the mechanical and electrical rooms. Custodial closets have been distributed throughout the school and sized to accommodate the latest HCPSS custodial services requirements.

The service area has direct corridor access to the center of the school, allowing for convenient deliveries and trash removal.


Exterior Building Changes

The community of Oxford Square will include residential housing with a traditional design aesthetic. That being said, and after working through several iterations of the exterior design with the developer, traditional building materials and design elements will be incorporated into the exterior facade of the school for compatibility with the surrounding community.

The exterior walls will be comprised of several colors of modular face brick (2-1/4”H. x 8”L.) in running bond pattern where the original prototype design utilized closure sized face brick (4”H. x 8”L.). Steep slope roof surfaces have been added to the design and will be covered with prefinished standing seam metal roofing where indicated above the main entrance stair tower and the recreation and parks activity room. The parapet walls at the flat roof areas will be capped with an exterior insulation finish system to provide the appearance of a precast concrete cornice. Finally, the exterior windows will be prefinished aluminum (project-out sash) with mullion subdivisions with rounded window heads and the exterior entrance frames will be a prefinished aluminum storefront product.

The main elevation comparison on the following page illustrates the significant transformation which has taken place to the ‘skin of the building’ from the Folly Quarter Middle School prototype design.

APPENDIX

Building Location

Middle School #20 has been placed at the most remote location from the railroad tracks on the school site. The distance between the school and the tracks is over 1500 feet. There is a significant elevation difference between the tracks and the school which is as much as 20 feet lower than the school. In addition to the change in elevation, there are other natural barriers between the school and the railroad tracks, such as a stream which is located north of the school site and a large wooded area to the north and west which will be preserved as part of the forest conservation agreement. Built structures will also be located between the school and the railroad tracks such as the existing warehouse north of the site and the future construction of community buildings to the west of the school.

Emergency Plan - Middle School #20

Middle School #20 • Construction Document Report A-1

Emergency Access

The school site can be reached either directly from Route 100 onto Coca Cola drive or from Route 1 via backroads that lead to Hi Tech Road which connects to Coca Cola Drive north of Banbury Drive. Once on Coca Cola Drive, there are two entrances into the Oxford Square development with connecting roads to the school site, therefore, providing two paved options for vehicles at any given time.

Evacuation Routes

Members of County agencies (Police, Fire and Rescue, Office of Emergency Management) have reviewed evacuation from the site via the access routes previously noted. Building evacuation locations and reunification areas will have the annual review that all school plans must undergo. The annual reviews will take into consideration any plan changes that need to be implemented due to future community development. This would include walking routes, traffic patterns and potential alternate shelter areas.

Building design

To provide a shelter-in-place facility in the event of potential pollutants being located directly outside of the building, the mechanical engineer has provided a HVAC system which will negate the possibility of pollutants being entrained into the building through the outdoor air intakes associated with the facility’s heating, ventilating, and air-conditioning (HVAC) equipment. This will be accomplished by utilizing passive and active safety measures included within the facility’s mechanical design to help safeguard the occupants during such a situation. These measures are described in greater detail in the following paragraphs.

The passive safety measures include both two-stage filtration within all rooftop units, as well as appropriate setbacks for all rooftop equipment from the roof’s edge. All rooftop units will be equipped with 2-inch thick MERV 8 pre-filters and 4-inch thick MERV 13 final filters. In addition, a minimum setback of 10-feet from the roof’s edge will be maintained for all rooftop equipment, helping to minimize entrainment of pollutant sources located at grade. Both of these items are routine safety measures for HCPSS school projects.

Active safety measures include an emergency outdoor air shut-off switch located within the administration area. When this switch is activated, the building automation system will close the outdoor air dampers associated with all rooftop unit equipment, allowing the units to still operate and function under a recirculation mode.

In addition, the building has on-site electrical generators and control logic provided as part of the building automation system that closes the outside air intakes to HVAC systems under a shelter condition. The active control measure described above is beyond the typical shelter scenario implemented on typical HCPSS projects.

Finally, all the windows, aluminum storefront and exterior doors installed at this school will comply with strict performance requirements to minimize outside air infiltration. Products are tested in accordance with American Standard Test Method (ASTM) E283 to determine compliance for minimal rate of air infiltration through exterior windows, curtain walls and doors.



Potential hazards

The rail line adjacent to the school property carries the same products typically transported over major highways. There is a voluntary ban on products with high hazard toxic/poison inhalation hazards due to the rail line passing through Washington D.C. Schools have emergency procedures in the event of outside environment contamination.

Pedestrian traffic crossing tracks is a potential hazard, therefore fencing and warning signage will be provided along the perimeter of the school site property.

Emergency responders

There is currently a fire and rescue station just 3 1/2 miles away from the school site at the intersection of Dorsey Road and Ridge Road. In addition, a second (new) station is scheduled to open in 2015 at the intersection of Route 1 and Montevideo road, which will also be 3 1/2 miles away.

(see image to right)

Summary

The location of the school site does not present exposures that require specific design alternations to the building. It is important that the HVAC system be capable of shutting down and windows closing to prevent a minimal amount of outside air into the building in the event of a shelter-in-place scenario. The HCPSS emergency plan template addresses the potential exposures currently anticipated for a school at this site. It is understood that the surrounding site will be developed after the construction of the school and will consist of commercial and residential buildings. Plans will be flexible to adjust to those changes to the surroundings and the above agencies will be consulted for input during the annual emergency plan review and appropriate changes will be incorporated.
