Door-Threshold-Model.pdf

This is an architectural drawing specification document for the Middle School Roof Replacement project in Michigan, detailing door-threshold construction at the roof interface. The drawing specifies the re-use of an existing threshold plate with new built-up roofing (BUR) application, incorporating two-ply stripping flashing, Tremco base adhesive, specified cant insulation, a new membrane layer, and surface-mounted metal counterflashing. The design accommodates the existing door frame, roof deck structure, and gravel surfacing typical of commercial roofing systems. The drawing is designated as DWG NO. 24 and is presented at a not-to-scale (NTS) reference, dated 2023, serving as a construction detail for the broader roof replacement scope of work.

No additional pricing information, timeline details, bid submission dates, site visit requirements, or contract terms are contained within this technical drawing specification. This document functions as a construction document component and should be reviewed in conjunction with the complete project scope of work, specifications manual, and contract documents for the Middle School Roof Replacement project to understand the full procurement requirements, budget parameters, and project delivery schedule.
