Curb-for-Air-Handling-Unit.pdf

This is a technical drawing specification document for a built-up roofing curb assembly designed to accommodate an air handling unit installation. The document provides detailed construction specifications for a curb system that includes a wood frame with 16-gauge minimum sealant tape, fasteners spaced at 8-inch on-center intervals with 18-inch on-center counterflashing attachments, and a two-ply stripping with gravel surfacing over specified built-up roofing insulation. The assembly accommodates both standard and alternate frame locations for heavy units, featuring gasketed fasteners with a minimum of two per side, and includes specified base, cant membrane sheet, and roof deck components. The drawing is noted as not-to-scale (NTS) and was created in 2023 using AutoCAD.

No information regarding pricing terms, contract duration, bidding procedures, response dates, site visits, bidder conferences, award dates, set-asides, incumbents, or funding sources is contained within this technical specification document. This drawing appears to be a component specification that would be included as a supporting exhibit within a larger solicitation package rather than serving as the primary contract document.
