WSDOT’s Progressive Design-Build (PDB) journey began in 2019 as a tool to bundle and accelerate delivery of hundreds of fish barrier replacements by 2030. As the heavy civil construction market conditions evolved in the post-pandemic aftermath, the Gateway Program received an unprecedented single submittal on a $500 million Design-Build (DB) contract. With a planned $600 - $700 million contract remaining to complete the program, the WSDOT team conducted in-depth industry engagement to determine how to deliver the remaining project, resulting in a strategy to split the final project into two with the more complex project with a longer duration proposed to utilize PDB delivery. This presentation highlights the efforts within WSDOT and state leadership to advance WSDOT’s first heavy civil PDB project, including developing the business case to executives and discussing the PDB process with lessons learned during the procurement and contract development. The procurement resulted in the selection of Kraemer-Scarsella Joint Venture (KSJV) to deliver the project. WSDOT and KSJV will present how they have developed a partnership and established a collaborative process to define and navigate the Phase 1 effort, including the delivery tools highlighted in KSJV’s winning proposal and utilized during the successful advancement of Phase 1.
