The $330.5m (£201m) contract for the design and construction of a storage and conveyance tunnel has gone to a joint venture of Traylor Brothers-Skanska-JayDee.
The Clean Rivers project is a 20-year, $2.6 billion programme designed to reduce combined-sewer runoff to the Anacostia and Potomac Rivers and Rock Creek by 96%. The contract will cover the design and construction of first section, the Blue Plains Tunnel, with excavation to begin in July. The joint venture of Traylor Brothers-Skanska-JayDee (TSJD) delivered the highest-scoring technical proposal and the lowest price.
"This contract award means actual shovels in the ground after years of planning," said DC Water general manager George Hawkins. "The Clean Rivers project will be the single most important step of a generation in improving the District’s waterways."
"TJSD is very excited about the Blue Plains tunnel project," said Traylor Brothers vice president George Williamson. "We have more than 65 years’ experience in tunnel design and construction and a tremendous depth in our engineering and management staff. Further, our team is rounded out by some exceptional local professional and construction subcontractors. We are confident in our ability to build an outstanding tunnel at Blue Plains."
