Pitch-Pocket-with-Grout.pdf

This is a technical drawing specification document for built-up roofing (BUR) construction detailing a pitch-pocket-with-grout assembly design. The drawing, designated as DWG No. 33, provides construction specifications for a hot/cold pitch pocket with grout used in roofing applications. The specification outlines the complete assembly process, including securing wood nailers to the roof deck using two staggered rows of fasteners spaced 24 inches on center, installing specified insulation, applying gravel surfacing with flange set in asphalt cement mechanically fastened at 3-inch intervals in a staggered pattern, and priming the metal flange before installing two-ply top-off with Tremco sealant. The metal pitch pocket must achieve a minimum 4-inch height and include specified drawband and sealant stripping.

The specification requires filling the pocket 1 inch from the top with non-shrink grout and installing a metal hood, with membrane placed under the primed metal flange and interior of the seal pipe base to prevent grout leakage into the building. The drawing is provided at NTS (Not To Scale) and appears to be part of 2023 construction documents. No pricing terms, funding sources, contract award dates, or procurement response deadlines are specified in this technical drawing. This document serves as a construction detail specification rather than a procurement solicitation and contains no information regarding set-asides, incumbent contractors, or contract renewal options.
