The U.S. Army Corps of Engineers has awarded a contract worth US$94.7 million to Heeter Construction Inc. for the installation of 278 high-capacity multi-strand rock anchors at Bluestone Dam in West Virginia.
The Corps’ Huntington District most recently extended bidding in July, which calls for the work to be done in accordance with its Dam Safety Assurance Program.
According to the program, a downstream hazard assessment indicates there is sufficient justification to modify the project to accommodate 100% of probable maximum flood.
The dam, which began operation in 1948, contains 55 monoliths. Work on the Bluestone Dam stability project began in 1998 and is being executed in five phases. This latest project is Phase 4, which includes the installation of high-strength anchors primarily over the stilling basin.
