3 EXECUTIVE SUMMARY EXECUTIVE SUMMARY Bruce Monroe at Park View Elementary School is among the schools included in the Department of General Services (DGS) FY 202 Phase Schools. These schools - all existing facilities - will be modernized to comply with the DC Public Schools (DCPS) criteria aimed to improve the learning environment, improve student performance, and advance educational outcomes within five years. The modernization of this school will be completed in a 3 phase process. This phasing allows the school to be occupied throughout the modernization process and provides an improved physical environment within the core learning areas at the earliest possible time. Because of the existing conditions at the Bruce Monroe at Park View Elementary School, the work that is to be completed under the Phase portion of the renovation will be supplemental to the typical Phase modernization projects. This Phase work is to be completed during the Summer of 202. This work is to be done under a modified design-build process where the builder is assigned to the project team during the Concept/Schematic Design phase. At the Design Development stage, the builder will develop a GMP at which time the architect s contract will be taken over by the builder from the DGS. PHASING SUMMARY The following is a preliminary outline of the project phasing: Phase : Core Academic Spaces including Classrooms, Corridors, Stairs, Restrooms, and Administrative Areas. New MEP/IT systems for these spaces. Phase 2: Academic Support Spaces including Cafeteria, Auditorium, Gymnasium, and Media Center. Complete ADA accessibility renovations. Phase 3: Remaining MEP/IT elements and outstanding site improvements. As stated in the Master Facilities Plan, the first priority is to improve the classroom learning spaces - the place the children spend most of their time. The Phase Modernization (Summer 202) will seek to provide improved lighting, environmental, acoustic, and technological qualities of the Core Academic Spaces. Where required, non-load bearing walls will be removed to create spaces that comply with the requirements of the Educational Specifications. In an effort to retain all historic elements possible the removal of existing elements will be limited in scope. En suite bathrooms, sinks, and storage areas will be included as required per the Education Specifications. In addition to the Phase modernization effort there are a number of stabilization issues that are to be addressed during this initial phase of construction. These issues have been identified by the school staff and include proper food storage in the Cafeteria, water infiltration, and potential air quality issues. According to the Education Specifications, the planned student capacity for Bruce Monroe at Park View Elementary School will be approximately 450 Pre-school through 5th Grade students. The original portion of this building was originally constructed in 96 with the addition of two wings in 93. The original composition of the school is largely intact however many modern codes (including ADA accessibility) and much of the building systems are beyond their useful life-spans. In addition to the code issues and the building systems, the historic interior finishes and exterior envelope have become covered up with the addition of modern building elements. The goal of this modernization will be to provide a fully modernized educational environment while maintaining the integrity of the historic context. In addition to the modernization of the school, we are proposing a restoration of this unique architectural structure to return it to its original glory. The full school modernization will include: Interior improvements: According to DCPS Five Priority Areas - Lighting, Environmental/Air Quality, Acoustics, Technology, and Furnishings. Re-Programming of Spaces as required: According to the Educational Specifications for 450 students Pre-School through 5th Grades. Building Envelope Restoration and Improvements. ADA Accessibility Site Improvements

4 ARCHITECTURAL NARRATIVE The original portion of the Bruce Monroe at Park View Elementary School was constructed in 96 with two additional academic wings added in 93. This historic architectural structure is built of brick with limestone ornamentation in the way of decorative quoins, window and door trim,and crenellation along the parapet. The 93 addition was built to match the original portion of the building and included educational spaces and spaces that were originally built as separate boy s and girl s gyms. A unique element of this school is the full sized Auditorium with stage that was built along with the 96 construction. Typically Elementary Schools were built with singular large spaces that served as Cafeteria, Gymnasium, and Auditorium. The overall building organization is symmetrical leading to a highly formalized building. An application which is still pending has been filed with the National Register of Historic Places for inclusion of the Bruce Monroe at Park View Elementary School. The design team will work with the DC Historic Preservation Office, the Commission of Fine Arts and all other historic preservation bodies to ensure that all renovation efforts maintain the integrity of this historic structure. The building is situated in the middle of the block so that the front and side setbacks are similar, with the main entrance in the middle of the block facing Warder Street. The overall building site is elevated from the adjacent sidewalk with the site sloping away from Warder Street with all site entries consisting of a series of steps. The main building entrance leads from a paved terrace centered on Warder Street, while the remainder of the site is bordered by a brick and stone retaining wall. This elevated building site poses considerable challenges when considering the requirements of ADA accessibility. The design team proposes a combination of re-grading a portion of the site with the introduction of stone walls and a ramp to provide an ADA accessible entrance at the southeast corner of the building site. The southeast corner of the site is being proposed because this is the portion of the site with the smallest difference in grade between the adjacent public sidewalk and school walkway. It is not feasible to alter the historic Warder Street entrance to the school as would be required to install the ramp. Instead the building entrance facing 6th Street NW is being proposed as the accessible entrance. While this entrance is not the formal main entrance, its prominent location on the site and direct access to the main corridor make this a reasonable ADA accessible entry point. The rear of the site contains a small parking area and a paved area immediately adjacent to the school. The design team is proposing that the parking area be expanded and that a loading area be created adjacent to the new kitchen. The remainder of the paved area at the rear of the building may be revised to include additional play areas once the loading requirement is accommodated. This reconfiguration of the parking and loading areas at the rear of the school will serve to separate the pedestrian/student circulation from the vehicular site access. The building is a split-level configuration with the entrance midway between the Ground and First Floors. In order to achieve the required ADA accessibility, the design team is proposing the introduction of a new elevator adjacent to the existing stairwell so that the any of the floors may be accessed from this entry. This split level design also leads to some confusion upon entering the school s main entrance. It is unclear upon entering where the building administration and security are located. The introduction of a welcome center flanked by the principal s office and the security office to the first floor at the top of the entry stairs will alleviate this confusion. This new welcome center will have an all glass wall and door facing the main entrance providing a visual connection to the reception area and creating a dynamic space upon entering the school. The existing building contains a large centrally located space on the second floor directly above the main entrance. Because of its location adjacent to the peak of the Auditorium roof, this is the only space within the building with both an eastern and a western exposure. This space is currently used in part as a classroom and in part as a larger meeting area. Under the proposed layout this space would become a state of the art Media Center centrally located at the heart of the building, accessible to students and the community. The addition of monitor type skylights would create a dynamic, brightly lit Media Center that would become a focal point for the school and could be used by the larger community. The proposed reorganization of the classrooms would provide groupings of classrooms by grade with the pre-k and Kindergarten classrooms located on the Ground Floor adjacent to the play structures that are appropriate for their specific age groups. The older children would be located on the second floor along with the Computer Lab for their use. This grouping of classrooms by age is conducive to the bi-lingual curriculum employed by this school. The reorganization also places the administrative and common functions of the school at the main floor where they are easily accessible to all portions of the school without disrupting the educational spaces. The existing interior finishes are largely the original plaster walls and ceilings with new fixtures and flooring throughout. The modernized spaces would include the installation of new acoustical ceilings to conceal the MEP components that are currently surface mounted. The existing corridors include marble base and aging VCT flooring. Research into the original building drawings indicates the possibility that terrazzo flooring may be under the VCT flooring in the corridors. Restoring this terrazzo flooring and removing the surface mounted elements would restore the original design to the school public spaces. The renovation of the Bruce Monroe at Park View Elementary School is an opportunity to restore this historic building to its original glory while providing a state of the art environment to the school and the overall community. Some highlights of the proposed renovation include the following: ARCHITECTURAL NARRATIVE An accessible site and building using a combination of a re-graded site, stone walls and ramp, a new elevator and the introduction of H/C lifts at the Cafeteria and Gymnasium. The reconfiguration of the rear of the site to provide additional parking and a dedicated loading area, separating the vehicular and play areas. New age-appropriate play structures located adjacent to the corresponding classrooms. A revised entry to the Cafeteria and Gymnasium with new interior windows linking these spaces to the adjacent Corridors. A new kitchen that is separate from the Cafeteria space with direct access to an exterior loading area. The introduction of a new welcome center at the main entrance to provide a clear path upon entry. A centrally located Media Center with natural light that will become a focal point of the school and can be used by the larger community. Replacement of the exterior doors and windows with modern components that meet DCPS efficiency standards, while retaining the original building elements style. Restoration of exterior building components to the original building materials. Removal of the roof addition to the two first floor offices on either side of the main entry.

5 MECHANICAL, ELECTRICAL, PLUMBING AND TECHNOLOGY SYSTEMS SCHEMATIC DESIGN NARRATIVE INTRODUCTION Allen &Shariff Engineering has been selected to perform the design of the mechanical, electrical, plumbing and technology systems for the modernization of the Bruce Park View Elementary School. The modernization will occur in phases as follows: Phase Classroom Modernization The first phase of the modernizations will focus on the Academic Components of the schools-the classrooms, where students spend the majority of their time. Improvements to the classroom shall be comprised of HVAC modifications/upgrades, interior finishes, lighting and electrical improvements, daylighting, technology enhancements, and FF&E. In addition to the modernization of the classrooms, consisting of new entries, flooring and wall coverings, wayfinding, and ceilings. Only with the proposed base system will the new HVAC be operational at the end of phase one. All alternates require the existing heating and cooling to remain in use for the renovated phase one areas. The spaces would not be able to utilize the new cooling/heating plants until the end of phase three. Phase 2 Support Spaces The second phase of the modernization effort will address support components, which may include bathrooms, art and music rooms, gymnasium, cafeteria, kitchen, media center, and health suite. Phase 3 Base Building System Components The final phase of the modernization will target the school s Systems Components, including - HVAC system (if required based on system chosen), plumbing system and fixtures, electrical system, the building s exterior envelope, including roof and windows, as well as technology system. Under the proposed base system, there will be no HVAC work to be accomplished under this phase. The following is the concept narrative for the mechanical, electrical, plumbing and technology systems for the school in it s fully modernized condition. MECHANICAL SYSTEMS General Mechanical Narrative: The building will be heated and cooled by a variable refrigerant flow (VRF) heat pump system, which will consist of multiple indoor units and outdoor condensing units. The VRF system will allow for maximum flexibility for phasing of the project and maintaining existing systems during the complete renovation schedule, while also providing a premium efficiency system. The distributed load on the roof will help to minimize any structural modifications, and the system will be operational at the end of phase one. The mechanical systems will be designed in accordance with the codes, guides and references listed below and to meet the energy performance requirements of the project. The mechanical systems will be designed and sized based on the design conditions listed below. We have estimated a building cooling load of 275 tons, based on a cooling requirement of one ton per 300 square feet of building area (82,000 gross). The cooling load for the renovated building takes into account energy recovery systems, recently completed fenestration replacement and no additional wall insulation. The existing building consists of a central steam heating plant and individual window A/C units. Ventilation, in the original wing of the building, is provided by a heating-only air handling unit in the basement mechanical room. The built-up AHU is original to the building. Individual ducts lead off of this AHU to the individual classrooms. This is a similar design to Cardozo High School. Per OPEFM, the ductwork was replaced in ASE will investigate reusing this ductwork in the new design. With the exception of the ventilation ductwork, all existing mechanical systems will be removed in their entirety by the end of phase three. The building will be designed with a fully integrated, direct digital control (DDC), energy management system (EMS). The EMS will control and/or monitor all mechanical equipment in order to maintain indoor design conditions during occupied periods. The EMS will also modulate mechanical equipment to maintain unoccupied set points. Control strategies will be implemented via the EMS to minimize the energy consumption of the MEP systems such as static pressure reset in VAV systems and Demand Control Ventilation. Additional HVAC systems will be designed for specialized areas in the school. Supplemental HVAC systems will be provided for areas requiring cooling over a 24-hour period. General exhaust systems will be provided as required by code, and for odor control, in areas such as locker rooms, kitchenettes, garbage rooms, janitor s closets, printing labs, art room, scene shop room and electrical closets (supplemental A/C units will be provided where the transformer load is over 6,000 Btu/h). Code required toilet exhaust systems will be provided for all toilet rooms. Specialized exhaust systems will be provided for fume hoods, kitchen hoods, and dishwasher hoods.
