Door-Threshold-Model.pdf

This is a technical drawing specification document for roofing work involving door threshold installation and built-up roofing (BUR) system modifications. The drawing (DWG No. 24) provides detailed construction specifications for a hot/cold door threshold installation that incorporates re-use of an existing threshold plate. The project scope includes application of adhesive, two-ply stripping flashing, specified Tremco base material, specified cant insulation, new membrane installation, new surface-mounted metal counterflashing, and gravel surfacing on an existing door roof deck. The drawing is presented at a scale of NTS (Not To Scale) and was created in 2023.

The document serves as a technical reference for construction execution rather than a procurement instrument. No specific contract terms, pricing information, quantities, response deadlines, site visit schedules, bidder meetings, award dates, or renewal options are detailed in this drawing specification. The document functions as part of the construction contract documentation package and would typically be included with related specifications and bid documents to establish the technical requirements for roofing contractors performing door threshold and built-up roofing work.
