Light-Metal-Parapet-Cap.pdf

This is a technical drawing specification document, DWG No. 36, detailing the construction requirements for a light-metal parapet cap installation. The drawing provides a cross-sectional view (Section A-A) of a roof assembly at the parapet wall interface, specifying the materials and installation methods required for this roofing component. The specification details include a two-ply Tremco roof membrane system installed over a specified roof deck with insulation, built-up roofing (BUR) with gravel surfacing, and base flashing. The light-metal parapet cap itself is to be installed with specific fastening requirements, including a continuous cleat fastened at 16-inch on-center spacing with fasteners spaced 24 inches on-center. The cap design incorporates a neoprene gasketed sealant between the wall, a nailer attachment point, and membrane installation over a Tremco nailer with 2-inch turn-down ends at a 45-degree angle. The drawing references Factory Mutual Data Sheet I-49 for additional performance specifications and indicates maximum spacing constraints of 10 feet.

The document establishes material and installation standards for this roofing component but does not specify pricing, contract terms, bid submission dates, or project funding information. This appears to be a technical specification document intended to guide contractors in the proper installation of the parapet cap assembly rather than a solicitation document containing bidding parameters or contract award details.
