ABERDEEN, Wash. - WSDOT is moving forward with a design-build contract to build pontoons to replace the aging SR 520 floating bridge. Three pre-qualified contractor teams were selected to submit proposals for this $300 million to $600 million contract that is expected to create approximately 2,000 project-related jobs at the height of construction in 2013.
The three selected teams are: Grays Harbor Constructors Joint Venture; Kiewit-General a Joint Venture; and Skanska, Mowat, Manson Joint Venture. The contractor teams must submit their proposals to WSDOT by Nov. 24, 2009, and WSDOT is expected to announce the apparent best value proposal before the end of the year.
The SR 520 Pontoon Construction Project includes the design and construction of a new pontoon construction facility in Grays Harbor County beginning in 2010, the design and construction of the new bridge pontoons, and storage of pontoons for the planned SR 520 floating bridge replacement or if they are needed in the event of a catastrophic failure.
