Community Flood Assistance & Resilience Residential Raise and Floodproof

The Washington State Department of Ecology's Office of Chehalis Basin is soliciting bids for a Community Flood Assistance & Resilience Residential Raise and Floodproof project through Invitation for Bids (IFB 2507 OCB). The procurement targets raising four residential houses approximately three feet above designated flood levels in three Washington counties: Grays Harbor, Thurston, and Lewis. The project spans multiple jurisdictions, including Aberdeen, Rochester, and Chehalis, with a comprehensive flood mitigation objective. Sealed bids are due by 3:00 p.m. local time on March 26, 2025, at the Department of Ecology office in Lacey, Washington. A voluntary pre-bid walk-through is scheduled for March 11, 2025, at 9:00 AM starting at 2506 Pacific Avenue in Aberdeen, with a subsequent voluntary pre-bid conference call on March 17, 2025, at 1:00 PM. The total project timeline requires 270 calendar days for substantial completion and an additional 30 days for final completion, with bidders expected to demonstrate technical capabilities in residential raising and flood mitigation strategies.

The procurement includes several notable participation and compliance requirements, with a mandatory 15% apprenticeship utilization provision. Voluntary participation goals include 10% Minority Business Enterprise (MBE), 6% Women Business Enterprise (WBE), 5% Washington Small Business, and 5% Veteran Owned Business. Subcontractor listing requirements are complex, with Form A (covering HVAC, plumbing, electrical) due within one hour of bid submittal and Form B (addressing structural steel and rebar installation) required within 48 hours of submission. Contractors must utilize the state's Access Equity (B2Gnow) system for compliance tracking and subcontractor payment monitoring. The estimated bid range for this project is between $981,000 and $1,200,000, suggesting a significant infrastructure investment in flood resilience. Potential bidders should be prepared to demonstrate expertise in residential construction, flood mitigation techniques, and compliance with state-level diversity and equity requirements.
