II. Executive Summary Purpose The purpose of this feasibility study is to explore options to increase the student capacity at Bethesda - Chevy Chase High

School to accommodate the projected enrollment at the school. The study evaluated a series of potential options that would satisfy the requirements of the educational specifications and space summary. The intent of this study is to provide Montgomery County Public Schools with specific recommendations and construction costs associated with the implementation of each proposed option.

History Bethesda - Chevy Chase High School was originally constructed in 1934. The school is named in honor of the two towns it

serves, along with Kensington and Silver Spring. Since the original construction, several additions have been constructed to the building. In February 2002 Bethesda - Chevy

Chase High School reopened after being revitalized and expanded. Methodology The existing school was evaluated by the design team to determine the most advantageous approach to adding the proposed

programmed spaces. Additionally, the study indicates the impact, if any, that can be reasonably expected as a result of each proposed option. The evaluation is based on compliance with Montgomery County Public Schools educational specifications.

The study is based on the following:

• Work sessions with the feasibility study participants & Montgomery County Public Schools Staff. • Analysis of existing site features and meeting with Montgomery County related to storm-water management. • Review of the educational specifications. • Research conducted by the design team.

II. Executive Summary (Continued) Overview Bethesda - Chevy Chase High School is comprised of the original building constructed in 1934, with 11 additions and

renovations that occurred over the past 79 years. The facility has several construction types which include steel - framed structure with an exterior masonry façade as well as masonry bearing wall construction. The northern portion of the building is four stories tall and contains a basement level. The bus loading entrance and portions east and south are three stories tall and share the same floor elevations with the northern portion. This area also surrounds a courtyard. Spread footings support the columns throughout the building with strap footings along the south side. At - grade levels contain a concrete slab on grade and the elevated floors are composite beam systems framing to steel columns. The roof is mainly framed with low slope steel joists with some roof features containing sloped joists.

Exterior concrete stairs and ramp lead upward from the bus loop to the first floor level. Numerous exterior concrete stairs and

ramps provide access to the east and south side of the building. The proposed building additions located along the north and west sides of the building are expected to minimally impact the

existing structure. Some new door openings are anticipated while renovation of the existing façade will be minimized as much as feasible in the areas directly impacted by the building additions. Some underpinning may be required, depending on the locations and elevations of the existing footings relative to new footings.

Vehicular access to the school is provided through two driveways located off of East - West Highway. One driveway serves as

the main entry to the bus loop and on - site parking. The second driveway, located along Chelton Road, provides access to the parent drop - off loop. Additional staff and visitor parking spaces are located along the access way. There are 234 parking spaces currently on - site. Sidewalks link the pedestrian circulation routes of the facility to the public sidewalks along Pearl Street and Chelton Road.

The current capacity at Bethesda - Chevy Chase High School is 1665, with an official enrollment of 1,835 students, and

enrollment projected to grow to almost 2200 students by the 2018-2019 school year. Long term, enrollment at the school is projected to increase to 2,300 students in the ten to fifteen year forecast.

II. Executive Summary (Continued) Proposed Options Three building addition options were developed with input from the feasibility study participants and Montgomery County Public Schools’ staff. Each option meets all of the programmatic requirements set forth by the educational specifications and explores different approaches of increasing the school capacity. All options will impact the existing building and site, however, the school will remain occupied and fully functional during construction. Common Design Elements All three options have the following common elements: Building

• Conform to current building standards and will be Americans with Disabilities accessible. • Increase the current capacity from 1665 to the maximum capacity of 2400. • Occupied school during construction. • Minimal disturbance of the existing building and academic curriculum. • Improve circulation in the existing building by allowing students to use corridors in the existing building that are currently under-

utilized. • Provide the same number of teaching spaces. • Provide, when possible, program relationship between new and existing teaching spaces by strategically locating new program in

close proximity and at the same floor elevation to the existing space.

Site

• Preserve existing vehicular and bus circulation through the site. • Provide a raised tennis court structure to accommodate six tennis courts and additional surface parking below. Provide access to

athletic fields between the raised tennis courts and the addition. • Require relocatable classrooms for any of the proposed options, (If any relocatable classrooms are required prior to construction, it

is recommended that they be located at the parking lot adjacent to the existing tennis courts.) • Require after school athletic program to occur offsite due to construction staging.

III. Scope, Methodology & Goals Scope and Intent The purpose of this feasibility study is to explore options for increasing the capacity of Bethesda - Chevy Chase High School by

evaluating a series of possible additions that will satisfy the requirements of the educational specifications dated September 21, 2012.

The intent of this feasibility study is to provide viable options for the proposed school expansion, to fulfill the educational program

requirements of students and staff, and respond to the concerns of the community. Each option addresses issues related to the incorporation of additional classroom space, additional parking on site, and site circulation. The scope of work also includes a limited survey evaluation of the existing mechanical, electrical and plumbing systems to determine if existing equipment could be extended to serve the proposed addition.

Work sessions were held at Bethesda - Chevy Chase High School on August 14, 2012, October 9 and October 24, 2012, and

November 8 and November 28, 2012. The design team analyzed the educational specifications and developed several options that would increase the capacity of Bethesda - Chevy Chase High School and address both building and site program. The feasibility study participants reviewed and evaluated the development of the building and site options at each work session. The comments and suggestions were discussed at each work session and incorporated when found to be practical and beneficial by those in attendance. The final options presented in this report are a result of comments and suggestions of the feasibility study participants, incorporated through the work sessions held at Bethesda - Chevy Chase High School.

III. Scope, Methodology & Goals (Continued) Methodology The existing school was evaluated by the design team to determine the most advantageous approach to adding the proposed

program spaces. Additionally, the impact, if any, that can be reasonably expected by adding to the existing facility and incorporating limited interior renovations was explored. The evaluation was conducted with the intent of adding to the existing school to comply with the educational specifications dated September 21, 2012. The evaluation is based on the following:

• Non - destructive visual evaluations, where possible, of the existing facility and follow-up interviews with Montgomery County

Public Schools staff. • Review of existing construction documents provided by Montgomery County Public Schools: The design team utilized existing

documentation to understand the existing building construction and systems. • Analysis of existing site features: Existing amenities, utilities, and site access were reviewed to determine if they were capable

of supporting the proposed options. • Analysis of geotechnical composition of the site: Montgomery County Public Schools contracted for a limited geotechnical

report to determine composition of existing soils and identify any rock and/or poor soil conditions on site. • Work sessions with the feasibility study participants & Montgomery County Public Schools staff: Work sessions established

the needs and goals for the study. • Review of the educational specifications: The review established a thorough understanding of the requirements and

objectives of the project.

General Site Information: The Bethesda - Chevy Chase High School is situated on a parcel comprising a 16.36 - acre lot at 4301 East - West Highway in Bethesda, Maryland. The site is zoned R-60 and is bounded on the south by East - West Highway (MD-410), on the east by

Chelton Road, on the west by Pearl Street and private development, and finally along the north by Sleaford Road.

IV. Existing Conditions (Continued)

Existing Site (Continued)

Based on the current Montgomery County Zoning Ordinance, dimensional regulations for the property include the following: Street setback - 25’ Side Setback - 8' Sum of Both Sides - 18' Rear setback - 20’ Maximum Building Height - 35' (3 stories or 40' if accepted by the Planning Board) Maximum Site Building Coverage - 35% Site Access, Parking and Circulation: On - Site Pedestrian and Vehicular Access : Vehicular and pedestrian access for the surrounding community is currently attained by five driveways (two from Chelton Road, one from East - West Highway and two from Pearl Street). The access from Chelton Road serves a student drop - off loop. The access from East - West Highway serves as the entrance to the bus loop and site parking. Lastly, the driveways on Pearl Street are for additional parking and the exit from the bus loop. All driveway entrances offer sidewalk connections to the right - of - way with Americans with Disabilities compliant handicap curb ramps and crosswalks. See site photo #1 in appendix VII. Driveway Entrances: All driveways are asphalt and appear to be in good condition. In terms of site distance, there does not appear to be any issues with the location and proximity of opposite and adjacent driveway intersections; additionally, the 25 mph speed limit on the surrounding streets likely reduces any risks that may be involved with these access point locations. Of the five driveways, the only two intended for two - way traffic are the main entrance from East - West Highway, and the parking lot entrance from Pearl Street. The remaining driveways are all intended for one - way use.

IV. Existing Conditions (Continued)

Existing Site (Continued)

Site Access, Parking and Circulation: Bus Loop: The schools bus loop is accessed from a two - way entrance off of East - West Highway. Buses circle clockwise in front of the high school and exit onto Pearl Street. The bus loop consists of a one - way 26 - foot drive aisle which circles around a parking lot in the southwest portion of the site. Although the bus loop driveways are shared with the smaller parking lot and loading areas, the queuing area is designated with signage for the sole use of the school buses during peak times. With approximately 17 bus parking spaces and 175 linear feet of queuing space it does appear that the loop is sufficient in size for the 18 routes currently serving the school. The bus loop also is demarcated as a fire lane for the school. See site photo #2 in appendix VII. Student Drop - Off Loop: The student drop - off loop is located on the eastern portion of the site, off of Chelton Road. The 20 - foot, one - way drive aisle with associated parking starts at the intersection with Lynbrook Drive and reconnects with Chelton Road 155 feet from the intersection with East - West Highway. From here, students can enter the building through the eastern side of the building. It is not known the number of parents utilizing the loop in a given day; however, the loop does provide over 380 - linear feet of queuing space (approximately 18 vehicles).

On-Site Parking:

There are three parking areas located around the site. The main parking area is located within the bus loop, on the south and west region of the property. This parking lot contains approximately 162 standard spaces (this figure includes several spaces that overlap the bus parking spaces) and 7 Americans with Disabilities compliant handicap spaces (1 is van accessible). This lot does not meet current Americans with Disabilities parking requirements. The small parking lot located in the northwestern corner is accessed by a two - way entrance and exit from Pearl Street. This parking lot contains 64 parking spaces, none of which are designated for handicap usage. This lot does not meet current Americans with Disabilities parking requirements. The parking area along the eastern boundary of the site is situated within the student drop - off loop. This lot contains 34 parking spaces, one of which is designated for handicap usage. This lot does not meet current Americans with Disabilities parking requirements. Overall, pavement and curbing is currently functioning. The most glaring needs of the parking areas center around the lack of Americans with Disabilities compliance. At a minimum, it is recommended that Americans with Disabilities accessible parking spaces with associated accessible routes be added to all parking lots. On - Site Loading:

The loading area is located on the southwestern corner of the building and is accessed through the bus loop entrance off of East - West Highway. The loading area has two docks, and is approximately 24 - feet wide and 60 - feet in length. Pedestrian access in this area is provided through the use of a concrete stairs; no Americans with Disabilities access appears to exist in this area. See site photo #4 in appendix VII.

Existing Site (Continued)

Page 28: BETHESDA - CHEVY CHASE HIGH SCHOOL

Bethesda - Chevy Chase High School Addition Feasibility Study Montgomery County Public Schools

27

Sidewalks: The existing site predominantly provides sidewalks around the perimeter of the building, with connections to the athletic fields and facilities throughout the campus. Overall, a good network of sidewalks is provided allowing users to move about the various facilities with relative ease. The major concern with the existing sidewalks is Americans with Disabilities compliance. Additionally, multiple areas throughout the site were observed with excessive gradients. At a minimum, an Americans with Disabilities compliant route is recommended for access to all areas of the property. See site photo #3 in appendix VII. Fire Access:

Currently, the bus loop and the student drop - off loop are serving as the on - site fire lanes. The bus loop and the drop - off loop are both in compliance with current fire lane dimensional requirements. The fire access lanes provide sufficient hose - reach around the structure to meet current fire code. Depending on the proposed layout, sufficient fire access will be required to cover all portions of the structure with a 450 - foot maximum of hose - lay. Site Topography: The site predominantly slopes from the building to the northernmost portions of the property. The areas of greatest topographic relief which include slopes greater than a 3:1 ratio occur between the building and the northern athletic fields and between the tennis courts and the baseball diamond. Overall, the site has a great deal of relief with several terraces. Depending on the improvements, the topographic character of the site could create issues. It is likely that the proposed site improvements will need to consider improved access to the athletic fields and it can be anticipated that ramps and retaining walls will be required. See site photo #5 in appendix VII.

Existing Site (Continued)

Page 29: BETHESDA - CHEVY CHASE HIGH SCHOOL

28

Vegetation: The majority of significant on-site vegetation consists of parking lot, street and shade trees. There also is a vegetated area at the southern portion of the site, as well as along the northern property line. As it is likely that there is little on the property that will qualify as forest, avoidance of certain areas may not be required. However, forest classification and the extent of forestation requirements will depend upon an accepted Natural Resources Inventory/Forest Stand Delineation. It should also be noted that impacts to root zones of specimen trees will require a variance from the County Arborist. Water and Sewer:

The existing building is served by an 8 - inch sewer main, contract #36104, built in 1936. The existing facility has two connections to existing 10 - inch water mains, contract #35111N, in the Chelton Road and East - West Highway right - of - ways which were built in 1937. The existing sanitary main is flowing from East - West Highway along the west side of the building heading north towards the existing tennis courts. The sanitary main turns east and continues along the existing fire lane between the stadium bleachers and building. The main again turns north, near Chelton Road, under the existing track, heading off the property. According to WSSC, the site is in a 495 pressure zone with a High Hydraulic Gradient of approximately 540 and a Low Hydraulic Gradient of approximately 460. On that basis, per WSSC prescribed calculations, the water pressure at the existing connection to the water main in East - West Highway is approximated to be between 50 psi and 107 psi The exact pressures and flows should be confirmed via field testing at the time of design. Gas, Electric and Telephone, Etc.: Power, cable and telephone service connections are made with the main service lines in the Chelton Road right - of - way. Power lines feed into the transformers at the northeastern corner of the existing building. Cable and telephone lines run into the facility from the Chelton Road right - of - way along the eastern edge of the existing building. Finally, gas mains are located in the East - West Highway, and Chelton Road right - of - ways, and it appears that the building is serviced by a gas connection from Chelton Road. There is no evidence of a natural gas connection to the building. Additionally, existing utility poles flank the site on all sides within the right - of - ways and should be avoided if possible.

Storm Drainage and Stormwater Management: The existing site is currently draining all runoff to the public stormdrain system located to the north of the property. It is anticipated that site improvements will be required to include ESD to the maximum extent practicable in order to treat all areas inside the limits of disturbance. After all ESD efforts are exhausted and the site still has not been able to reach a hydrologic state of “woods in good condition,” then structural practices may be permitted as determined by Montgomery County Department of Permitting Services. Potential ESD stormwater management practices for the site include both micro - scale practices and alternative surfaces. Micro - scale facilities could include the utilization of bio - swales and micro - bioretention facilities around the parking areas. Site Soils (Geotechnical): Per the Soil Survey of Montgomery County, Maryland the predominant soils on the site are in the Glenelg, and Urban Land series. According to the USDA, the depth to bedrock is generally greater than 6 - feet in these soils. However, it should be noted that these estimated depths are based upon virgin soils. Because the site has been previously disturbed, bedrock could be encountered at shallower depths. It will be necessary to perform site-specific borings to establish the actual depths to bedrock. In terms of hydrology, the majority of soils are in the Glenelg Series. These soils have a 'B' hydrologic soil group classification and are known for good infiltration. Flood Plains, Stream Valley Buffers and Non-Tidal Wetlands: Initial investigations reveal that the site is located outside of a floodplain in a zone “X” on FEMA Flood Insurance Rate Map number 24031C0455D. Furthermore, according to the U.S. Fish and Wildlife Mapping services there are no wetlands or associated buffers located on or around the site.

Existing Building MECHANICAL General Bethesda-Chevy Chase High School was originally constructed in 1934, with subsequent building additions constructed

between 1936 and 2002. A modernization of the entire school was performed in 2002, that provided a comprehensive replacement of the facilities' mechanical system. The following is a detailed description of the existing mechanical, plumbing, and fire protection systems.

Heating Systems

Two scotch - marine boilers and one copper - fin boiler produce heating water for the building. Located within the ground floor boiler room, this equipment was installed during the 2002 modernization and is currently functioning. The scotch-marine boilers support a majority of the facilities heating water demands, with the copper-fin boiler producing heating water during summer operation. Wall-mounted combustion air openings are currently provided for each boiler, with openings positioned high and low for compliance with current International Mechanical Code (IMC) requirements for combustion air. The gas service for the building is located outdoors, adjacent to the boiler room area. Manufactured by Burnham Boilers (Model 3PW-250-50-GO-GP), each scotch - marine boiler has a gross output rating of 8,369 MBH. While the existing boilers are functioning adequately to satisfy the existing school, there does not appear to be surplus capacity to support the overall size of the planned addition without losing standby capacity in the event that one boiler fails. Individual 24 - inch flues extend from each boiler and are ducted separately to the roof. Each boiler is provided with a dual - fuel type burner (Model F14-GO-50), with natural gas currently supplied to each burner. Each burner is rated for a 10,461 cubic feet per hour (CFH) natural gas consumption and a 75 gallon per hour (GPH) number two fuel oil consumption. Gas trains are provided with a pressure reducing valve and two shut - off valves for CSD - 1 compliance. Manufactured by Lochinvar (Model PBN-1000), the copper-fin boiler has a gross output rating of 880 MBH, with a single 14 - inch flue extending to the roof. The boiler’s gas - fired burner is rated for a 1,000 CFH natural gas consumption. Similar to the scotch - marine boiler, the gas train is equipped with a pressure reducing valve and two shut-off valves for CSD - 1 compliance.

V. Description of Proposed Options (Continued) Option 2 (Continued) Structural

This option consists of an 80,000 SF addition to the northwest portion of the existing school. This option places most of the new classroom space over the existing stadium. Utilizing double loaded corridors to service the classrooms at the main and second floor levels. More columns are required to support the increased area over the stadium compared to option 1. While the columns extend closer to the field, minimal columns attempt to lessen the impact of sight lines around the stadium area. A concrete slab on grade supports the grade level spaces while floor framing consists of a 5 - inch concrete and composite metal deck supported by composite steel beams and girders. The roof consists of 1.5 - inch metal roof deck supported by steel joists and steel girders. The structure is supported by steel columns. It is anticipated that spread footings can be utilized to support the columns and strip footings under load bearing and exterior walls. Lateral support is provided by a combination of shear walls along the ends of the new space and steel moment frames. Alternatively, steel floor - floor trusses located at the exterior and corridor walls with strategically placed vertical and sloped members to account for door and window openings could provide a framing option to reduce the number of columns while providing framing that can either be showcased or hidden within the structure. The result is greater spans, less columns, and more efficient framing. Concrete basement walls at the lower level provide soil retention in areas of varying grade elevation around the new building addition. Existing retaining walls near the football field may need to be checked for loading from the new addition.

V. Description of Proposed Options (Continued) Option 3 Description Option 3 is located in front of the existing main entrance on the northwestern side of the site. The Option investigates raising the

proposed addition to accommodate the existing bus loop. The option provides two - stories of loop circulation for a connection to the existing fourth floor. An exterior courtyard separates the existing building from the new addition allowing for natural light to the existing facility. The raised addition provides a new main entrance, including an interior stepped plaza while providing cover over the existing bus loop. Option 3 provides 76 additional parking spaces. The main parking lot and tennis courts will be required for contractor staging. During construction, the secondary parking lot along Pearl Street will be temporarily used as bus drop - off and pick - up.

Proposed Addition Option 3 achieves the program requirements by connecting two separate areas of the building through a new core space. This creates a new main entrance to the school connecting academic program on either side. These new spaces can be used during lunch periods to accommodate a large number of the student population. The first cluster is located on one of the existing tennis courts and includes a lower level, main level, and an upper level. The lower level is comprised of one classroom, support program, and an auxiliary gymnasium located in proximity to the existing locker rooms and the stadium field. The existing stair serving the gymnasium will provide vertical access to the new auxiliary gymnasium. The main level has a new administrative area which would offer good views to the new parking structure and rest of site. The second floor includes four classrooms. The second cluster consists of an addition that utilizes columns to elevate a double loaded corridor on three levels above the existing bus loop and maintain the existing fire lane from Chelton Road. Within the first floor of the elevated addition includes five classrooms, two special education support areas, a multipurpose laboratory, and a science laboratory. The second level includes six classrooms and a technology education laboratory. The top level includes ten classrooms, an art laboratory and connects to the existing school’s fourth floor to create a more viable education core.

• Loop circulation is tight to core of the existing building. • Provides additional classrooms on 4th floor allowing for a more viable classroom core on the existing 4th floor. • Minimal disturbance to stadium field and physical education program (daily classes) during construction. • Potential to create continuous new façade.

Option 3 Three - Dimensional Model - From Front

Disadvantages

• Colonnade at bus loop obscures view to the entrance, creates security concerns, and reduces visual access from the administration to parking area.

• Most difficult option to phase. • Most difficult constructability option. • Courtyard between existing building and

addition will be indirect sunlight. • Greatest disturbance of curriculum during

construction. • Temporarily relocates bus traffic and main

entrance onto Chelton Street. • Most amount of parking lost during

construction. • Exhaust from buses (air quality concerns). • Athletic program would not be able to hold

events due to the lack of parking during construction.

V. Description of Proposed Options General Three design options for expanding Bethesda - Chevy Chase High School have been developed in response to the Montgomery County Public Schools educational specifications. Each option provides a different design approach in addressing the requirements of the educational specifications and construction impacts to the existing facility.

All three options propose a lower level addition to the northwest side, connecting the proposed gymnasium program to the existing locker rooms on the lower level. All three options include a main level and second level additions in varying locations. The proposed options require minimal disturbance to the existing facility and academic program.

It is anticipated that the proposed scope of work will take 18 to 24 months of construction with anticipated completion by the 2017-2018 school year.

Common Design Elements

Building

The following proposed additions are common to all three options.

• Conform to current building standards and will be Americans with Disabilities Act accessible. • Increase the current capacity from 1665 to the maximum capacity of 2400. • The existing school will be occupied during construction in all options. • Minimal disturbance of the existing building and academic curriculum. • Improve circulation in the existing building by allowing students to use corridors in the existing building that are currently

under-utilized. • Provide the same amount of classrooms. • When possible all options, provide program relationship between new and existing teaching spaces by strategically

locating new program in close proximity and at the same floor elevation to the existing space. • Earliest start of construction is summer 2015 with completion expected by August 2017.

V. Description of Proposed Options (Continued) Common Design Elements (Continued)

Site Modifications Due to an increasing student enrollment, Bethesda - Chevy Chase High School is currently planning on adding relocatable classrooms on site. It is recommended that the relocatable classrooms be located away from the proposed construction staging zones, so that they will not need to be moved at the start of construction. The parking lot adjacent to the existing tennis courts is recommended as the desired location for any relocatable classrooms placed on site. It is anticipated that up to 16 relocatable classrooms will be in place prior to the start of construction. A new raised tennis court structure with surface parking below will also be added to the site.

Parking and Site Circulation The current bus loop has been verified to be adequate in functionality and is visibly accessible from the administrative area. The student drop - off is off of Chelton Road and provides additional Americans with Disabilities Act staff parking spaces. Current parking is adequate for staff only; student parking on site is limited. All options provide Americans with Disabilities Act access on site to a raised tennis court structure to accommodate six tennis courts and provide additional surface parking below. Access to athletic fields is provided between the raised tennis courts and new addition.

Elevated Tennis Courts Raised tennis courts provide additional parking spaces below and are supported by cast - in - place concrete slab and beams and concrete columns. This maximizes column spacing while providing adequate anchorage for fences, nets, and equipment required for the tennis court area. The use of cast - in - place concrete minimizes the effects of vibrations, which are typically a concern with such spaces that are lightly loaded and subjected to athletic activities. It is estimated that columns spaced 25’ to 30’ on center would adequately support the concrete framed structure consisting of concrete girders, approximately 36 to 48 inches deep, concrete beams 24 - inches to 36 - inches deep, and an elevated concrete slab 6 to 8 - inches thick. The structure is supported by spread footings and the lateral system consists of concrete beam/column moment frames. The existing retaining wall along the south side of the tennis courts may need to be modified or replaced to account for space and loading requirements of the new structure.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) The site circulation will be generally modified for all options as follows:

Provide additional spaces to accommodate for the increase of students and staff projected enrollment.

Renovation of vegetation in parking lot to increase visibility of pedestrians.

Fire truck access will be maintained via the existing fire lane and extend through to Pearl Street.

By expanding the current parking lot and by increasing visibility, drop - off traffic congestion will be reduced and overall site safety for all users is improved. Stadium and Baseball Field The existing stadium and baseball field are in adequate condition. The location of the fields remains the same in all options. If the stadium field is disturbed during construction, it is Montgomery County Public Schools’ responsibility to bring it back to current condition.

A new Americans with Disabilities Act access ramp linking the existing stadium field to the rest of the site.

In options 1 and 2, additional stadium seating will be provided to make up for lost seats, and, seats with obstructed views.

In order to increase use of the existing stadium field, an astro-turf field was proposed as an add-alternate.

Water and Sewerage Within options 1 and 2 portion of the existing sanitary main that is under the new addition will be replaced to meet the plumbing

code. All new sanitary connections from the new addition will connect to the new main internally under the new addition. An on - site sewer connection for the sewer line displaced by the building addition will be provided.

Similarly, option 3 requires that the existing sanitary main on the west side of the building that is under the new addition will be

replaced to meet the plumbing code. All new sanitary connections from the new addition will connect to the main internally under the new addition. An on - site sewer connection for the sewer line displaced by the building addition will be provided.

V. Description of Proposed Options (Continued) Common Design Elements (Continued)

Building structural system

Bethesda Chevy - Chase High School is comprised of the original building constructed in 1934, with 11 additions and

renovations occurring over the past 79 years. The facility has several construction types which include steel framed structure with an exterior masonry façade as well as masonry bearing wall construction. The northern portion of the building is four stories tall and contains a basement level. The bus loading entrance and portions east and south are three stories tall and share the same floor elevations with the northern portion. This area also surrounds a courtyard. Spread footings support the columns throughout the building with strap footings along the south side. At-grade levels contain a concrete slab on grade and the elevated floors are composite beam systems framing to steel columns. The roof is mainly framed with low slope steel joists with some roof features containing sloped joists.

Exterior concrete stairs and ramp lead upward from the bus loop to the first floor level. Numerous exterior concrete stairs

and ramps provide access to the east and south side of the building. The proposed building additions located along the north and west sides of the building are expected to minimally impact the

existing structure. Some new door openings are anticipated while renovation of the existing façade will be minimized as much as feasible in the areas directly impacted by the building additions. Some underpinning may be required, depending on the locations and elevations of the existing footings relative to new footings.

Mechanical

HVAC System All options present a significant increase in the overall size, capacity, and square footage of the existing school. As

discussed in the existing conditions section of this study, the existing heating water plant does not appear to have surplus capacity to support the overall size of the planned addition without losing standby capacity in the event one boiler fails. In addition, the additive capacity of both chillers does not appear to have surplus capacity to support the existing school and overall size of the existing school planned addition. Therefore, utilizing the existing chilled and heating water systems to support proposed addition is not feasible.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) MECHANICAL (Continued)

To support the proposed addition, two solutions are available: •Option A: Replace the existing boilers (both scotch-marine and copper fin types), water-cooled chiller, and cooling tower with larger capacity equipment sized to support both the existing school and building addition. Higher efficiency equipment, such as condensing boilers, a variable frequency drive centrifugal chiller with magnetic bearing compressors, and a cooling tower system with variable frequency drive fans, is recommended. Existing pumping systems would be supplemented or replaced as required to support the facilities increased chilled and heating water demands. Equipment would need replaced or modified in phased manner, minimizing the disruption to the existing school. This approach centralizes the chilled and heating water plants, eliminating the need to provide a support area within the addition for new heating and chilled water infrastructure. In addition, the location of the existing ground floor boiler room and third floor mechanical room align well with the placement of the planned addition(s), allowing for pipe routing between the mechanical rooms and the addition area without significant disruption to the existing facility. The potential drawback to this approach is the current age of the existing central heating and cooling plant equipment, which were replaced as part of the 2002 modernization. •Option B: Utilize a stand - alone central heating and cooling plant to support only the building addition. A series of high - efficiency condensing boilers and new air - cooled chiller would be utilized. The use of an air - cooled chiller in lieu of a water - cooled chiller is recommended due to the anticipated capacity of this equipment. Utilizing a ground - source geothermal system to support the proposed addition does not appear to be a feasible due to site limitations and the anticipated size of the geothermal borefield. This approach minimizes the disruption to the existing chilled and heating water systems. However, it does require additional square footage within the building to accommodate the new heating and chilled water equipment. In addition, it does not provide improved overall energy efficiency of the existing chilled and heating water systems supporting the existing building.

Based on the two mechanical options described above, Option A is the recommended approach for the addition. This option minimizes the addition’s square footage requirements for supporting the chilled and heating water infrastructure. In addition, it centralizes this infrastructure for the entire facility, rather than having independent plants for both the existing building and addition. Finally, it provides a solution that helps to improve the energy efficiency of the entire facility.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) MECHANICAL (Continued)

Space conditioning for classroom, science, technology, and multi-purpose areas within the building addition would be accomplished through a series of four - pipe vertical fan coil units with a minimum of one fan coil unit provided for supporting each space. These units would be positioned within support closet areas adjacent to the classroom served. Doors for support closets would be from the corridor for maintenance access. New chilled and heating water distribution piping would be provided for supporting the new fan coil unit systems, with these piping systems extending from the new chilled and heating water infrastructure described previously. The administration and counseling offices would utilize a variable refrigerant flow system with an energy recovery type air - cooled condensing unit for space conditioning. Indoor units would consist of cassette - type units installed at the ceiling level. Individual branch controllers would be provided at each indoor unit, allowing for independent heating or cooling operation within each zone, as well as simultaneous heating and cooling system operation for the system. Conditioned outdoor air for the classroom and administration areas would be supplied though multiple rooftop dedicated outdoor air systems, each complete with a chilled water cooling coil, hot water heating coil, enthalpy type energy recovery wheel for pre - conditioning of the outdoor air, and a plate - and - frame heat exchanger for tempering and pre - conditioning supply air. Airflow supplied from these units will be dehumidified, conditioned, and delivered directly to each space at a room neutral temperature. Space conditioning for other stand - alone areas within the addition, such as the wrestling room, would be accomplished through a dedicated single - zone variable - air volume rooftop air - handling unit. Air - handling unit systems would be provided with a chilled water cooling coil and hot water heating coil for space conditioning. Each science laboratory and storage area would be provided with exhaust though a series of rooftop exhaust fans. Toilet rooms, storage rooms, and other heating - only areas will utilize hot water unit heaters connected to the facilities central heating plant. Building automation system controls for the proposed addition will be direct digital type, manufactured by Andover Controls, and complete with electric and electronic actuation. All new control components will be networked to the central Montgomery County Public Schools energy management system for occupied/unoccupied settings and other energy management routines.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) MECHANICAL (Continued)

This type of system provides the most sustainable and energy efficient solution and delivers the most flexibility at the lowest cost for both current and future needs.

PLUMBING Plumbing Systems

To support the building addition’s cold and hot water requirements, new piping systems would need to be extended from the existing piping mains located within the ground floor boiler and locker room areas to support the addition. These piping systems would extend to new plumbing fixtures provided located throughout the addition. New plumbing fixtures would be designed to meet the Americans with Disabilities Act and utilize water conservation features. Floor - mounted water closets should utilize dual - flush type valves, capable of providing either 1.6 or 1.0 gallons per flush. Urinals should be wall - hung and provided with pint flush valves. Wall - hung cast - iron lavatories should utilize self - closing faucets that supply 0.35 gallons per minute. The water consumption figures noted are equal to or less than what is required by both current plumbing code and LEED water conservation requirements.

Fire Protection System

The existing fire protection system and associated fire pump for the existing school building would be extended to handle the building addition. It is anticipated that these systems have sufficient capacity for the additional building area. New zone valves would be extended from the existing fire main; with sprinkler piping extending from the zone valves provided at each floor level to support the addition. New air - handling units and dedicated outdoor air system supplying 2,000 cubic feet per minute or more of airflow would be equipped with smoke detectors in both the supply and return air ductwork.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) ELECTRICAL Power Distribution It is proposed that a new main circuit breaker be installed in the existing 4000A main distribution switchboard to serve electrical equipment in the proposed building addition. The new addition will have a 277/480-volt distribution panel and will be sized to serve the mechanical, lighting, and plug loads in the addition. The electrical room in the proposed building addition will have electrical equipment to serve the addition. This will consists of new 277/480-volt panelboards for mechanical and lighting loads, step-down dry - type transformers, and 120/208-volt panelboards for general receptacle and computer loads. The new receptacle panelboard will be fed from a standard dry - type transformer and will serve general receptacles and plug loads in the addition. The new computer panelboard will be fed from a K - rated dry - type transformer and will serve designated receptacles in the classrooms of the addition. Generator Power The existing generator can be utilized to serve the life - safety emergency lighting for the proposed building addition. The current Montgomery County Public Schools standard is to provide emergency power for both life safety systems and standby power for the heating system in order to keep the building from freezing. It needs to be determined if the existing generator has the capacity and can be used to serve both life safety systems and standby power for the heating system in the addition. A larger or additional generator may be required to accommodate both the standby and heating loads of the addition. In turn, an additional automatic transfer switch (and associated generator panelboards and transformer) will be required in either the existing main electrical room or the electrical room of the addition to serve the standby and heating loads in the addition.

V. Description of Proposed Options (Continued) Common Design Elements (Continued) ELECTRICAL (Continued)

Lighting Montgomery County Public Schools standard classroom lighting will be provided in the classrooms of the proposed building addition. This will consist of energy - efficient fluorescent pendant fixtures. Lighting controls will include occupancy sensors and multiple levels of lighting per Montgomery County Public Schools standards. Lighting controls will also meet the requirements of ASHRAE Standard 90.1-2010, Section 9.4.1.4, which includes automatic daylight controls (photocontrol with dimming ballasts) for daylight harvesting, where required. Fire Alarm System The existing fire alarm control panel will remain and be reused to serve fire alarm devices in the proposed building addition. Initiation devices and notification devices will be located to meet code requirements. Intercom and Sound Systems Intercommunications devices will be provided throughout the proposed building addition. This will include speakers and call switches in the classrooms and speakers in the corridors. The existing intercom head - end console may need to be upgraded to increase the capacity for the new spaces. Voice and Data Systems The existing voice and data systems will be expanded to the proposed building addition. The outdated video system will not be expanded in the addition. A telecommunications closet will be required in the addition to serve the classrooms in the addition. The number of outlets in each room will comply with Montgomery County Public Schools and Maryland State requirements. Security System The existing security system will be expanded for the proposed building addition. Intrusion detection will include motion detectors/sensors and door contacts. Video surveillance will include dome cameras in the corridors and building exterior.
