Flashing-for-Non-Wall-Supported (1).pdf

This is a technical architectural drawing (DWG No. 11) specification for built-up roof hot/cold wall flashing design related to a Middle School Roof Replacement project in Michigan. The drawing provides detailed construction specifications for non-wall-supported deck flashing systems utilizing a specified built-up roof (BUR) membrane with two-ply fasteners spaced 8 inches on center. Key components include one-piece counterflashing, specified sealant application, roof deck insulation, gravel surfacing installed into reglet and secured with lead wedges at 8-inch intervals, flexible vapor retarder as insulation retainer, wood nailer secured to deck with fasteners in two staggered rows spaced 24 inches on center, stripping specified base flashing, and wood cant nailed to sheet blocking in two rows spaced 12 inches on center in a staggered pattern. The drawing specifies a minimum clearance of 4 inches and is drawn to a not-to-scale (NTS) notation.

The specifications indicate standard roofing construction practices and material requirements for the flashing assembly, with compressible insulation and appropriate fastening protocols detailed throughout the design. No specific pricing terms, set-asides, contract duration, funding sources, or award information is contained within this technical drawing document.
