Central West Headquarters Re-Roof

The Central West Headquarters Re-Roof project, solicitation PW#2025-028, involves comprehensive roofing work at 1403 W Howe St, Seattle, WA. The scope includes removing and disposing of existing built-up roof membranes and corrugated metal siding, installing tapered polyisocyanurate insulation, coverboards, and new EPDM roof membranes on flat roofs, and installing a standing seam metal roof on the vaulted roof. Additional requirements include raising parapet height, installing sheet metal flashings, coping, safety rails, and ladders. An optional structural upgrade, Additive No. 1, involves installing a 5/8 inch plywood roof diaphragm. The total estimated contract value ranges from 581,072 dollars for the base bid to 718,688 dollars if the additive is included. The procurement is managed by the City of Seattle Public Works and is evaluated using a best-value trade-off approach. A significant portion of the award criteria is based on Women- and Minority-Owned Business Enterprise (WMBE) participation, with a 16-point scoring system focusing on WMBE guarantees, aspirational goals, and business support strategies. Bidders must submit a mandatory Inclusion Plan and adhere to a 30 percent minimum self-performance limit for WMBE bidders. Compliance is strictly monitored through utilization reports and written agreements, with failure to meet goals potentially resulting in payment withholding or debarment. The project is governed by local Seattle ordinances and Washington state laws, including RCW 39.04.350 for responsible bidder requirements.
