Roof-Hatch-Model.pdf

This is a technical drawing document for a built-up roofing (BUR) system specification. The drawing illustrates a hot/cold roof hatch assembly and details the layered construction methodology for roofing installation. The specification outlines a multi-ply roofing system incorporating a base sheet, BUR membrane, insulation layer, cant sheet, counterflashing, two-ply stripping, and gravel surfacing applied over an existing deck. The drawing is designated as Sheet 2023 and is presented at a not-to-scale (NTS) reference, providing contractors and construction teams with the technical requirements for roof hatch installation and the overall roofing system composition.

The document serves as a technical reference standard rather than a procurement document and does not contain information regarding pricing, timelines, bidding requirements, contract terms, funding sources, or award details. This drawing would typically be incorporated as part of a larger construction project specification or scope of work to communicate roofing material specifications and assembly requirements to bidders and construction contractors.
