Pitch-Pocket-with-Grout.pdf

This is a technical drawing specification document (DWG No. 33) for built-up roofing installation, detailing the construction of a hot/cold pitch pocket with grout assembly. The specification outlines the complete assembly requirements for a roof penetration detail, including a wood nailer secured to the roof deck with staggered fasteners spaced 24 inches on center in two rows, specified insulation layers, gravel surfacing set in asphalt cement with mechanical fastening at 3-inch intervals, and a metal pitch pocket with a minimum 4-inch height. The assembly incorporates a two-ply top-off using Tremco sealant, a prime metal flange with membrane underlayment, and a drawband with sealant stripping. The pitch pocket and interior seal pipe base are primed to prevent grout leakage into the building structure.

The specification requires filling the pocket to 1 inch from the top with non-shrink grout and installing a metal hood for weather protection. The document provides a non-to-scale reference drawing and appears to be from a 2023 project documentation set. No pricing information, contract timeline, bidding procedures, award dates, or funding sources are provided in this technical specification sheet. This appears to be a standard roofing detail specification for inclusion in construction contract documents rather than a standalone procurement notice.
