Light-Metal-Parapet-Cap.pdf

This is a technical drawing specification document for a light-metal-parapet-cap installation detail, providing construction guidance for roofing and flashing work. The drawing (DWG No. 36) presents a section view (Section A-A) illustrating the proper assembly and attachment methods for a parapet cap system. The specification details a two-ply Tremco roof membrane system installed over roof deck insulation with built-up roofing (BUR) and gravel surfacing. Key components include continuous base flashing, a neoprene gasketed sealant application between the wall and flashing, and a metal nailer attached to the parapet wall using continuous cleats fastened at 16-inch on-center intervals with a minimum 4-inch to maximum 10-foot vertical span. The membrane sheet is installed over the Tremco nailer with 2-inch turn-down ends at a 45-degree angle, and fasteners secure metal flashing sections at 24-inch on-center spacing. The specification references Factory Mutual Data Sheet I-49 for additional technical requirements and guidance.

No pricing information, bid response dates, contract award dates, set-asides, or procurement-related details are contained in this technical drawing. The document serves purely as a construction specification and detail drawing to guide contractors in the proper installation and material coordination for the light-metal-parapet-cap system as part of a larger roofing project. The scale is noted as "NTS" (Not to Scale), and the drawing is identified as part of a 2023 sheets and views model.
