This is a technical drawing specification document for roofing equipment installation, specifically detailing a round-to-square metal flashing and storm collar assembly for built-up roofing (BUR) systems. The drawing (DWG No. 20) provides comprehensive specifications for a two-piece soldered metal flashing component designed to transition from existing round roof penetrations to square configurations. The assembly includes a sheet metal clamped storm collar, Tremco sealant bead application, treated wood blocking, insulation materials, and integration with existing wood curbs and BUR membranes. The specifications are scaled as "not to scale" (NTS) and dated 2023, indicating current construction standards applicable to the project.

The document serves as a fabrication and installation guideline rather than a procurement specification or contract document. No pricing terms, quantities for order, response deadlines, bid dates, site visit requirements, or award information are included in this technical drawing. The specification establishes the performance requirements and construction methodology for field-soldered connections and material integration during roof assembly work, with all components requiring coordination with specified roof decking, existing structural elements, and weather protection systems. This drawing would typically be referenced as part of larger project specifications and bid documents for roofing contractors or equipment suppliers.
