Equipment-Stand-Rain-Collar.pdf

This is a technical drawing specification document for built-up roofing installation and equipment support systems. The drawing (DWG No. 20) provides detailed construction specifications for a round-to-square metal flashing system designed to accommodate equipment penetrations through existing roofing. The specification calls for a two-piece soldered metal flashing fabricated in the field, with a round-to-square sheet metal clamped storm collar to manage water drainage. The system integrates multiple components including treated wood blocking, wood curb support, insulation per specification, Tremco sealant bead, and built-up roofing (BUR) membrane installation around an existing round roof penetration.

The drawing is presented at a Not-to-Scale (NTS) ratio and appears to be part of a 2023 construction document set. The specifications reference existing roof conditions and call for materials and installation methods conforming to industry standards for commercial roofing applications. This technical specification would typically be included within a broader contract scope for roofing work, structural improvements, or facilities maintenance projects requiring equipment installation or roof penetration management.
