This bill establishes new fenestration certification requirements for public works contracts in Washington State, specifically for projects involving the construction, alteration, repair, remodeling, or improvement of fenestration products or systems. It introduces a new section to chapter 39.04 RCW, mandating that for contracts awarded on or after January 1, 2028, contractors must hold a national glazing contractor certification and employ at least one worker with a national technician certification. By January 1, 2029, at least 25% of employees performing fenestration work must also hold a national technician certification. Compliance with these requirements must be documented in bid submissions and is a condition for contract award and payment.

Additionally, the bill amends existing legislation (RCW 39.04.350) to include the new certification requirements as part of the responsibility criteria for bidders on public works contracts. It specifies that bidders must submit documentation of compliance with the certification requirements outlined in the new section. The bill also provides for the development of supplemental criteria for determining bidder responsibility by state or municipal agencies, which must be included in bidding documents. The effective dates for various sections of the bill are set for January 1, 2027, with certain provisions expiring on July 1, 2027.
