Creates new statutory authority by adding sections to chapter 47.20 RCW and chapter 39.10 RCW that permit the Washington State Department of Transportation and regional transit authorities to use a roster-based multiple award task order contracting process for construction, renovation, repair, or improvement projects. This is a procedural change that authorizes a specific contracting method (multiple award task order contracts using rosters), establishes how contractors are added to rosters, and sets requirements for solicitations, evaluations, and awards. For the department, awards may go to the responsible bidder with the lowest price or to the best value; RTAs must solicit written proposals from one or more rostered contractors they determine are qualified. The bill prescribes procurement procedures and evaluation criteria, including safety approach and history, approach to executing the work, and record or plan for including certified small, veteran-owned, and other socially and economically disadvantaged business enterprises. It requires the department to include a representative from its office of equity and civil rights on evaluation committees and requires RTAs to publish recurring notices inviting statements of qualifications and to include protest procedures with a minimum four-business-day filing period. Both the department and RTAs must comply with applicable apprenticeship utilization and prevailing wage laws. Reporting obligations are added: the department must report roster use and participation by small, veteran-owned, and disadvantaged firms to the capital projects advisory review board and to legislative transportation committees (upon roster establishment and each September thereafter); RTAs must report regularly to their governing body and legislative transportation committees with specified roster and contract metrics. The affected entities include the Washington State Department of Transportation, its office of equity and civil rights, regional transit authorities authorized under chapter 81.112 RCW, the capital projects advisory review board, legislative transportation committees, OMWBE, and certified small, veteran-owned, and disadvantaged business enterprises. The text provided does not include an effective date, does not formally define key terms such as "roster," "multiple award task order contract," or "best value," and does not specify the exact frequency for RTA "recurring intervals" or "regular" reporting, nor does it cite specific statutes for apprenticeship and prevailing wage compliance.

If enacted, the department of transportation and regional transit authorities will maintain lists of prequalified contractors they can quickly call on for building, repairing, or improving roads, bridges, stations, and related facilities, and they will be able to award individual task orders from those lists either to the lowest responsible bidder or on a best-value basis. That likely speeds procurement and gives firms on the rosters ongoing opportunities to compete for work, while evaluation rules and required outreach and reporting aim to increase participation by certified small, veteran-owned, and other disadvantaged businesses. The department and RTAs will take on new administrative duties and some recurring costs: setting up evaluation committees (including an equity representative), advertising recurring calls for qualifications, documenting why contractors are limited for particular solicitations, complying with apprenticeship and prevailing wage rules, and making regular reports to oversight bodies and legislators. Contractors must be prequalified to join rosters and may benefit from more frequent bid chances, but key implementation details such as exact timing, definitions of terms like “roster” and “recurring intervals,” and the bill’s effective date are not specified in the provided text, leaving some uncertainty about how quickly and uniformly these changes would take effect.
