IFB IGSA #A60S1-24-DPW-005 Reform Roofing – Buildings 172, 2001, 1659

Replace the asphalt roofing systems on the Fort AP Hill Buildings (3). Each building has adifferent configuration.Building 172: is a 3-story building, approximately 5,746TSF. The building dimensions are approx. 61’ x 34’(Approx Roof Surface Area– 3,091SF) with an additional entry roof approx. 14’ x 4’ (approx. 140SF). Thebuilding height is approximately 35FT from grade to the highest roof peak, with approximately 11/12 pitchon the roof and approximately 20FT to the eaves. This building currently does not have gutters.Building 2001: is a 1-story, L-Shaped building, approximately 1600SF with block walls. The main rectangularsection of the building measures 60’x20’; and is attached to one side of this main section. A smaller wingextends 40’ in length and 20’ in width, forming L-shape (approx. roof surface area 1,787SF - See Drawings)The building height is approximately 15FT from grade to the highest roof peak, in a hip style, withapproximately 10FT to the eaves. The truss span is 24” on center. Power is fed to the building through anelectrical service mast (i.e. pipe) through the roof. Building 2001 has three (3) weather tracking deviceslocated on the rooftop that need to be handled with extreme care and placed back exactly as they sitcurrently. A valid ID is required daily, to work at this location. There is also no smoking or cell phone usageof any kind within the gates of this location.Building 1659: is a 1-story dining facility (DFAC) approximately 11,750SF. The building dimensions areapprox. 125’ x 94’ (approx. 13,251SF) with an additional entry roof over the entry doors (29’ x 12’) total ofapprox. 471 square feet. The building height is approximately 28FT from grade to the highest roof peak,with approximately 5/12 pitch on the roof, with approximately 10FT to the eaves. This building currentlydoes not have true gutters (currently only a small section above a few HVAC systems). The existing roof isasphalt shingle on a gable style, wood construction framing, spaced 32” on center, with double plywood forthe decking. Decking consists of 5/8” CDX for the base layer of sheathing, and ½” OSB sheathing for the toplayer of sheathing; with a 5/12 pitch. The entry area roofing system is also wood construction, but spaced16” on center, with a single layer of plywood, which is assumed to be the 5/8” CDX. Currently all decking issecured with nails and are backing out. The existing failing roofing system has exceeded its life expectancy and requires replacement using modern materials and methods that meet or exceed the performance of the original construction.
