AN ACT Relating to prime contractor bidding submission requirements on public works contracts;
HB 1633 changes Washington’s public works bidding rules for prime contractors on certain large projects. For public building, public works, and higher-education construction, alteration, or repair contracts expected to cost $1 million or more, the bill requires each prime bidder to identify, at the time of bid submission, the subcontractors it intends to use for specified scopes of work. Those scopes include HVAC, plumbing, electrical, structural steel installation, and rebar installation. The bidder must also provide proof that the listed subcontractors are licensed, and any errors in that proof must be corrected within 24 hours of submission.
The bill also limits substitutions of listed subcontractors and makes a bid nonresponsive if the bidder fails to list required subcontractors, names itself without being licensed for the work, or lists multiple subcontractors for the same category without meeting the bill’s conditions. It preserves several exceptions, including substitutions for refusal to contract, bankruptcy, inability to perform, licensing or bonding problems, inability to provide a bondability letter, or legal disqualification. The bill expressly does not apply to design-build, general contractor/construction manager, or job order contracting procurement methods. It also directs the Capital Projects Advisory Review Board to study current subcontractor-listing practices and report back with recommendations on expanding listing requirements, improving transparency and fairness, and setting thresholds and timeframes for additional scopes of work.
HB 1633 amends state public works contracting law by adding mandatory subcontractor-listing requirements to RCW provisions governing prime contractor bids on qualifying public projects. It changes bid submission procedures, creates new grounds for deeming bids nonresponsive, restricts post-bid subcontractor substitution, and adds a reporting/study requirement for the Capital Projects Advisory Review Board. The bill primarily affects public owners, prime contractors, and subcontractors working on large state, municipal, and higher-education construction projects, especially in the mechanical, electrical, and structural trades.
The bill appears to have been broadly supported and noncontroversial in the legislative process. It passed House and Senate committee votes unanimously or near-unanimously, and both chambers approved it with no recorded opposition on the final votes. The overall tone suggests agreement that the measure would improve transparency and competitive fairness in public works bidding while addressing concerns about bid shopping and bid peddling.
The main policy tension is between transparency/fairness in bidding and flexibility for contractors and subcontractors. Supporters, as reflected in the bill text, emphasize preventing bid shopping, ensuring listed subcontractors are committed at bid time, and improving access to public works for minority- and women-owned businesses through clearer rules. Potential concerns are that the new listing requirements and strict nonresponsive rules could reduce bidder flexibility, increase administrative burden, and limit substitution options, though the bill’s exceptions and its exclusion of alternative delivery methods appear designed to address some of those concerns.
