Department of Community and Human Services (DCHS) Sobering Center

King County's Department of Community and Human Services (DCHS) is soliciting bids for construction of a new sobering center at 1950 1st Avenue South, Seattle, Washington, with a non-mandatory pre-bid conference on November 17, 2026 and bids due December 15, 2026. A reciprocal preference for resident contractors applies, and nonresident contractors from states that give bidding preferences to their own residents are subject to a comparable percentage disadvantage calculation. Bidders must attend one of two mandatory site tours, on December 1, 2026 at 1:00 p.m. or December 3, 2026 at 11:00 a.m., because failure to attend results in a non-responsive bid determination.

The County sets a 15% minimum Small Contractors and Suppliers (SCS) utilization requirement and a 15% minimum Apprentice Utilization Requirement. The work consists of demolition and new construction primarily on the first floor of the existing building, with limited support construction in the basement and second floor. Subcontracting opportunities are identified for concrete, metals, wood and plastic composites, finishes, fire suppression, plumbing, HVAC, and electrical work. Contractors must comply with prevailing wage requirements under Chapters 39.12 and 49.28 RCW. Contract execution is contingent on King County receiving all permits listed in Section 01 41 00.

The engineer's estimate is $2.95 million. Each bid must include a bid guaranty bond of at least 5% of the total bid price, payable to King County. Upon award, the contractor must furnish a Performance and Payment Bond equal to 100% of the contract price, executed by a surety registered with the Washington State Insurance Commissioner. Bids exclude Washington State retail sales tax, which the County adds to progress and final payments. Bid opening occurs via Microsoft Teams immediately after the December 15, 2026 deadline at 1:30:59 p.m.
