U.S. seeks rock anchors for Bluestone Dam stability project

HUNTINGTON, W.Va. 5/30/12 (PennWell) — The U.S. Army Corps of Engineers plans to take bids for installation of 278 high-capacity multi-strand rock anchors at Bluestone Dam on the New River in West Virginia. A solicitation is to be issued in June, with a site visit scheduled June 18.

Based on current hydrologic and structural criteria, the Corps’ Dam Safety Assurance Program found potential exists for initiation of failure of Bluestone Dam at a water elevation below the top of the dam. A downstream hazard assessment indicates there is sufficient justification to modify the project to accommodate 100 percent of probable maximum flood.

The dam, which contains 55 monoliths, began operation in 1948. Work on the Bluestone Dam stability project began in 1998 and is being accomplished in five phases. The Corps currently plans to seek bids for Phase 4, which includes installation of high-strength anchors, primarily over the stilling basin.

The majority of the 278 anchors are to have 61 strands up to 270 feet in length. The contract is to consist of a base of 104 anchors with eight options: 14 anchors, 12 anchors, 13 anchors, 11 anchors, 22 anchors, 27 anchors, 39 anchors, and 36 anchors. The work is valued at $25 million to $100 million.

A pre-solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W9123712R0005 in the “Keyword/Solicitation #” box. A site visit and pre-proposal conference are scheduled June 18.
