2005 AASHTO National Value Engineering Award: Most Value Added Proposal Preconstruction Engineering
The I-405 Storm Water project scope included storm water collection, conveyance, storage and treatment along 22 miles of I-405, the second largest North-South artery supporting Seattle, Redmond, Bellevue and Renton. MENG Analysis identified drainage system planning and construction alternatives that offered first cost or life cycle cost benefits and improved project quality.
MENG Analysis provided a total of 21 proposals yielding a total savings potential of $68,784,000. This savings represents 83% of the total project cost, with additional savings to be realized as proposals are applied to WSDOT's future projects.
