Equipment-Stand-Rain-Collar.pdf

This is a technical drawing document (Drawing No. 20) that provides specifications for built-up roofing equipment and rain collar installation. The document outlines a two-piece soldered metal flashing system designed to transition from round to square configuration around roof penetrations. The specifications detail the fabrication and installation of a round-to-square sheet metal clamped storm collar that incorporates Tremco sealant, treated wood blocking, insulation, and a cant strip around an existing wood curb. The drawing is presented at not-to-scale (NTS) and is part of a 2023 sheets and views model set.

The document serves as a technical specification guide rather than a procurement document with pricing, quantities, or contract terms. It provides construction and material specifications for contractors responsible for the roofing system installation, including details on the membrane type (BUR), existing round penetration treatment, and the sequence of installation for the flashing components. No information regarding cost, timeline, bidding procedures, or contract duration is included in this technical drawing.
