Metal-Sleeve-and-Storm-Collar.pdf

This is a technical drawing specification document for a Michigan middle school roof replacement project, detailing the construction requirements for a built-up roofing (BUR) system with metal sleeve and storm collar installation. The drawing provides detailed specifications for the roof assembly, including the integration of a metal sleeve with a storm collar, wood nailer securing methods, built-up roofing components, insulation layers, and proper fastening procedures. The specification requires two rows of staggered fasteners spaced 24 inches on center, gravel surfacing, two-ply stripping set in specified mastic, a primed flange, and caulked drawband with elastomeric sealant. The storm collar flange must be fastened at 3-inch intervals with mechanical fasteners and sealed with mastic at the metal sleeve perimeter. The drawing is marked as "Not to Scale" (NTS) and dated 2023.

The document serves as a technical reference for contractors bidding on or executing the roof replacement work, establishing the required materials, assembly methods, and quality standards for the roofing system penetration detail. No pricing information, bid response dates, performance timelines, or contract award details are contained within this technical specification drawing.
