Pitch-Pocket-with-Grout.pdf

This is a technical drawing specification document for the Middle School Roof Replacement project in Michigan, detailing the construction requirements for a built-up roofing (BUR) pitch pocket assembly. The drawing (DWG No. 33) provides comprehensive specifications for installing a hot/cold pitch pocket with grout, including the attachment of wood nailers to the roof deck using two rows of staggered fasteners spaced 24 inches on center. The assembly requires specified insulation, gravel surfacing set in asphalt cement with mechanical fasteners spaced 3 inches on center in a staggered pattern, and a metal pitch pocket with a minimum 4-inch height. The specification calls for priming of the metal flange before application of two-ply top-off material with Tremco sealant, inclusion of membrane under the prime metal flange to prevent grout leakage, and filling the pitch pocket to 1 inch from the top with non-shrink grout and a metal hood.

The drawing is presented at a scale of "Not to Scale" (NTS) and includes detailed technical specifications for materials and installation methods essential to the roof replacement project. No information regarding pricing terms, bid deadlines, site visit requirements, bidder conferences, contract award dates, contract terms, set-asides, or funding sources is contained within this technical specification document. The drawing serves as a construction standard to ensure proper installation of roof penetration details during the project execution phase.
