The Corps of Engineers announced it awarded a $180 million contract for the construction of Portugues Dam, a 220-foot-tall, 1,230-foot-long concrete arch dam planned for Puerto Rico.
The Corps’ District office in Jacksonville, Fla., awarded the contract to Dragados U.S.A. Inc. of New York in March, following several delays. (HNN 2/5/08)
The dam is part of the Portugues and Bucana Rivers flood control and recreation project on the Portugues River northwest of Ponce. The Corps previously estimated construction could cost $100 million to $250 million.
Construction involves 367,000 cubic yards of roller-compacted concrete. Appurtenant structures include an integral spillway and intake. Work also includes foundation excavation in rock, placing foundation concrete, foundation grouting, and development of an on-site quarry.
