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

This is a technical drawing specification document for a built-up roof hot/cold wall flashing system designed for non-wall-supported deck applications. The drawing (DWG No. 11) details the roofing membrane configuration and flashing installation requirements, specifying a two-ply built-up roof (BUR) membrane with fasteners spaced at eight-inch on-center intervals. The system includes a one-piece counterflashing, specified sealant, and roof insulation installed over the specified roof deck with gravel surfacing. The design incorporates a flexible vapor retarder serving as an insulation retainer, wood nailers secured to the deck with staggered rows positioned twenty-four inches on-center, and stripping with specified base flashing installed at twelve-inch on-center intervals with staggered blocking and wood cant nailed to the sheet. The minimum measurement for the counterflashing is four inches.

The document provides construction detailing and material specifications essential for proper roof flashing installation and does not contain procurement information such as pricing, set-asides, award dates, contract terms, or response deadlines. This appears to be a technical reference drawing used to communicate roofing assembly requirements to contractors or construction professionals, with all dimensions and material specifications noted as either "specified" or "as specified," indicating that detailed requirements are provided in accompanying specification documents.
