Curb-for-Air-Handling-Unit.pdf

This is a technical drawing specification document for a curb-for-air-handling-unit installation, though the specific contracting agency or jurisdiction is not identified in the provided content. The drawing details the construction specifications for a built-up roofing (BUR) hot/cold base flashing curb designed to accommodate air handling units on roofed structures. The technical specifications include requirements for sealant tape, a 16-gauge minimum frame, wood curb construction, fasteners positioned at 8-inch on-center spacing with 18-inch on-center counterflashing, two-ply stripping with specified base flashing adhered to the roof deck, gravel surfacing, and insulation materials. An alternate frame location is noted for heavy-unit installations, with gasketed fasteners required at a minimum of two per side. The drawing is presented at a not-to-scale (NTS) format and references various specified materials and components throughout the design.

No pricing terms, contract timelines, response dates, bid due dates, site visit information, bidders' conferences, award dates, contract terms, renewal options, set-asides, incumbent information, or funding details are provided in this technical drawing document. The file functions primarily as a design specification and does not contain typical contract opportunity information such as procurement timelines or financial requirements.
