THE HIGH SCHOOL WAS DESIGNED AND CONSTRUCTED BETWEEN 1949  1952, OPENED IN 1952, AND CLOSED IN 2013. THE BUILDING IS A CONTRIBUTING STRUCTURE TO THE YOUNG, BROWN, PHELPS AND SPINGARN EDUCATIONAL CAMPUS HISTORIC DISTRICT. THE PROJECT IS SUBJECT TO THE 9B PROCESS AND HAS RECEIVED PRELIMINARY DESIGN APPROVALS. SINCE THE BUILDING CLOSED IN 2013 IT HAS BEEN SUBJECT TO VANDALISM, AND OPPORTUNISTIC SCAVENGERS. THE BUILDING HAS ENDURED SEVERAL FIRES, AND THE INTERIORS HAVE BEEN EXPOSED TO THE ELEMENTS AND EXHIBIT SIGNIFICANT WATER DAMAGE. CORE AND SHELL: THE SCOPE OF WORK INCLUDES STABILIZATION AND SELECTIVE RESTORATION OF THE EXISTING TO REMAIN MASONRY FACADE, EXTERIOR WINDOWS, EXTERIOR DOORS, SLOPED SLATE ROOF AND FLAT MEMBRANE ROOF. THE FOUR STORY BUILDING WITH THE GROUND LEVEL PARTIALLY BELOW GRADE IS STRUCTURED WITH REINFORCED CONCRETE AND STEEL, AND ENCLOSED BY A BRICK MASONRY CAVITY WALL ASSEMBLY. SELECTIVE REPAIR AND STABILIZATION OF THE STRUCTURE IS INCLUDED IN THIS WORK, ALONG WITH BUILDLING ENVELOPE MODERNIZATION. THE EXISTING BUILDING STAIRS AND CORRIDORS ARE EXISTING TO REMAIN; ONE NEW ELEVATOR IS PLANNED FOR THIS PROJECT. THE ANCILLARY BOILER HOUSE BUILDING IS PLANNED FOR RENOVATION AND MODERNIZATION. THE EXISTING BRICK MASONRY WALL WILL BE DISASSEMBLED AND REBUILT AS THE BASE OF NEW WALL AND ROOF CONSTRUCTION, RAISING THE HEIGHT OF THE ROOF FOR THE PROPOSED WMATA MECHANICAL SHOP. THE ORIGINAL SMOKE STACK IS EXISTING TO REMAIN AND NOT PART OF THIS SCOPE. INTERIORS: THE INTERIOR SCOPE OF WORK INCLUDES ABETMENT AND FIRE PROTECTION THROUGHOUT THE BUILDING. THE SPRINKLER SYSTEM WILL BE INSTALLED IN TWO PHASES, WITH THE FIRST PHASE IN THE NORTH HALF OF THE BUILDING. FULL MODERNIZATION AND FIRE SUPPRESSION OF THE UNOCCUPIED SOUTH SIDE OF THE BUILDING WILL OCCUR AS ADDITIONAL SPACE IS DEVELOPED WITHIN THE BUILDING. A 3-HOUR RATED PARTITION SEPARATES THE NORTH / SPRINKLERED SIDE OF THE BUILDING FROM THE SOUTH SIDE. THE DCIA PROJECT REQUIRES APPROX. 50,000 SF OF THE TOTAL 226,500 SF. THE 50,000 SF IS SPREAD OVER TWO FLOORS ON THE NORTH HALF OF THE BUILDING.

THE REMAINING 176,500SF OF EXISTING BUILDING WILL BE SECURED AND CONVERTED INTO A COLD DARK SHELL IN PREPARATION FOR FUTURE REUSE. THE ORIGINAL GYMNASIUM, AUDITORIUM AND LIBRARY ARE NOT PART OF THIS SCOPE BUT ARE SEEN AS SOCIALLY SIGNIFICANT AND ARE PROPOSED AS REHABILITATION ZONES. PLANNED WORK INVOLVES A LEVEL 2 ALTERATION, BUILDING ADDITIONS, AND A CHANGE OF OCCUPANCY TO A HISTORIC BUILDING. THE RESTORATION AND REHABILITATION ZONES ARE INDICATED ON THE DRAWINGS.
