On March 11, 2024, WSDOT awarded the contract to Skanska. Skanska has teamed up with AECOM as the lead designer to complete this design-build project. Over a 25-year partnership, Skanska and AECOM have collaborated on 38 heavy civil construction projects worth $8.5 billion. Their joint expertise includes highway construction, signature bridges, complex interchange work and marine highway infrastructure.
This project was awarded as a design-build contract, which means WSDOT completed the preliminary design of the project and then put out a bid to find a contractor to complete the final design and construct the project.
Key advantages to the design-build process include:
- The designer and builder can closely collaborate at the same time. As a result, complicated projects find innovative solutions faster.
- This design-and-build collaboration saves time and can significantly shorten the overall project timeline.
WSDOT is committed to providing equitable contracting opportunities to minority-owned, women-owned, veteran-owned and disadvantaged small businesses (MSVWBEs). Our goal is to provide 26 percent of our transportation projects’ contract value to these firms.
