The bill amends RCW 39.04.360 to establish clearer timelines and responsibilities regarding change orders for additional work on public and private construction projects, excluding private residential projects of 12 units or less. It mandates that owners, states, or municipalities must issue a change order within 30 days after satisfactory completion of additional work requested by contractors, subcontractors, or suppliers. If they fail to do so, interest will accrue on the unpaid amount at a rate of one percent per month. Additionally, contractors and upper-tier subcontractors are required to issue change orders to lower-tier subcontractors within 10 days of receiving an approved change order.

Furthermore, the bill outlines the process for requesting change orders, stating that contractors must request a change order from the owner, state, or municipality within 30 days of completing additional work. It also specifies that if a contractor or subcontractor has made a timely request for a change order, they will not be liable for interest on unpaid amounts if the change order is not issued. The bill allows aggrieved parties to bring civil actions for violations, seeking relief that includes interest and reasonable attorneys' fees.
