Central West Headquarters Re-Roof

The Central West Headquarters Re-Roof project at 1403 W Howe St, Seattle, WA 98119 involves the complete removal and disposal of existing built-up roof membranes down to the wood and plywood decks, along with the removal of corrugated metal siding at the gable ends of the barrel vault. The scope includes installing tapered polyisocyanurate insulation with the first layer mechanically fastened and subsequent layers fully adhered, followed by a new EPDM membrane on flat roofs and a standing seam metal roof with underlayment on the vaulted sections. The project requires raising parapet heights to accommodate the new insulation, installing new sheet metal flashings and coping, safety rails, and ladders. An optional structural upgrade involving a 5/8-inch plywood roof diaphragm is available as Bid Additive #1, increasing the total estimated contract value from $581,072 to $718,688. The solicitation is issued under PW#2025-028 by the City of Seattle’s Public Works Division, with a response deadline of August 19, 2026. The contracting office is located in Seattle, WA, and the project is governed by municipal procurement rules rather than federal FAR clauses. The evaluation and award process is centered on a trade-off methodology weighted heavily toward Women- and Minority-Owned Business Enterprise (WMBE) participation. Bidders are scored on three components: aspirational WMBE goals (up to 6 points), WMBE guarantees (up to 6 points), and business support strategies (up to 4 points), requiring a minimum of 10 total points to be considered responsive. Contractors must ensure at least 30% of the work is self-performed by certified WMBEs as mandated by City Specifications Section 1-08.1(3), and all WMBE commitments become binding contractual obligations upon award. Compliance is enforced through mandatory reporting, strict substitution restrictions requiring prior written approval, and potential deficiency ratings for underperformance or documentation failures. The contract requires active SAM.gov registration, adherence to prevailing wage laws, and compliance with state RCW statutes. Payment and invoice procedures, accounting codes, and formal contracting officer designations are not detailed, but administrative oversight is managed by Seattle Public Works personnel including the Capital Project Coordinator and Construction Contracts Specialists. There are no specified FOB terms, packaging requirements, inspection protocols, or technical standards beyond the WMBE compliance
