Marine Barracks Washington Quarters 6 Renovation

Marine Barracks Washington Quarters 6 Renovation Marine Barracks Washington, 801 G Street, SE Wash., DC $5-10 Million The project renovates the historic Marine Barracks, Washington: Quarters 6 (15,984 SF) at 8th and I Streets in Washington D.C. Quarters 6 is the residence of the Commandant of the U.S. Marine Corps. The scope of the project was determined by a condition assessment (MBW Government Officers Quarters 3 & 6 Comprehensive Study, April 2021) performed by an architectural and engineering firm. The repairs include structural, architectural, fire protection, mechanical, and electrical repairs, as well as anti terrorism upgrades and hazardous material abatement. Structural work to be performed is exterior shell repairs including repointing brickwork, replacing rotten wood, repair spalling concrete, and framing. There is significant water damage from water infiltration requiring repairs to the south porch roof above the solarium ceiling. Interior structural repairs include repairs to existing joists and replacing the existing concrete solarium floor slab and framing. Quarters 6 has several different roofing systems including slate shingle, asphalt shingle, galvanized steel, ethylene propylene diene terpolymer (EPDM), standing seam metal, and thermoplastic polyolefin (TPO). The project repairs sections of galvanized steel roofing, removes and replaces existing EPDM roof membrane, and repairs all holes and penetrations on the standing seam metal roof. Additional repairs include removing the existing TPO roofing system, including roof membrane, sheet metal flashing and trim, penetration flashing, and insulation, down to the existing wood plank roof deck and installing new fully-adhered polyvinyl chloride (PVC) roof membrane with flashing, drainage system, and solar panel system. The architectural work includes restoring flooring, brickwork, masonry, painting, and repairs to interior finishes including refurbishing damaged plaster in compliance with historical guidelines. The fire protection work includes replacing all existing fire suppression system and fire alarm system components. Mechanical repairs are extensive and include replacing dedicated outdoor air systems (DOAS), providing a louvered penthouse, four duct risers in the bedroom closets, eight 250 CFM (cubic feet per minute) registers, two 750 MBH (thousand British Thermal Units (BTUs) per hour) gas-fired, condensing boilers, two 75 GPM (gallons per minute) primary heating water pumps, one 45 ton air cooled chiller with remote condenser, two 90 GPM primary chilled water pumps, and two 90 GPM dual-temperature water pumps, as well as provide a new controls system and replace all piping risers and plumbing piping. Electrical repairs will replace all the existing incandescent specialty lamps in the antique lighting fixtures with energy efficient L.E.D. lamps, provide a dedicated Telecommunications Room and also replace the elevator system, electrical panels, and telecommunications wiring, cables and devices. User Generated Unit Costs were used for this project and include the cost of features to meet the minimum DOD anti-terrorism (AT) standards. The AT line item includes standard anti-terrorism measures such as mass notification systems, emergency shutoffs for ventilation systems, laminated glazing, and emergency lighting and signage. The AT upgrades include a glazing system on the windows, a blast curtain (e.g., SAFETYDRAPE), and upgrades to exterior doors and locks. All windows are to be custom fabricated to replicate the historic appearance of the original windows. All hazardous materials including asbestos containing material and lead based paint will be abated. Project materials and methods will comply with historic preservations guidelines." *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. PRE-PROPOSAL INQUIRY (PPI) CUTOFF DATE: November 23, 2022.
