“We are thrilled to announce these pre-qualified teams for the pontoon design-build project,” said Mike Cotten, Design-Build Manager for the SR 520 Bridge Replacement and HOV Program. “We look forward to seeing how the teams propose innovative ideas to deliver the project on time, within budget and with the highest level of quality.” Contractor teams will also be asked to outline their plans for addressing environmental regulations and outreach to tribes and communities.
In order to help crews begin pontoon construction as quickly as possible, WSDOT recently awarded a $2,756,000 contract for an innovative pontoon testing effort to Quigg Brothers, Inc. This research and development effort involves field-testing various pontoon construction methods and techniques at Satsop Business Park in Satsop, WA to provide detailed design information for the design-build contractor. Crews will begin this testing work later this summer and finish by the end of the year.
