U.S. extends bidding for dam safety civil construction at 3.65-MW Stampede Dam

The Bureau of Reclamation has extended the deadline for bids from small businesses to perform dam safety civil construction at 3.65-MW Stampede Dam on California’s Little Truckee River. Bids now are due April 5.

Reclamation previously called for bids by March 29. Stampede Dam is part of Reclamation’s Washoe Project, which also includes Marble Bluff Dam and Prosser Creek Dam.

The agency issued a draft environmental assessment in 2011 endorsing a plan to modify Stampede Dam to prevent its failure during extreme floods by increasing the height of the 239-foot-tall zoned earthfill dam by 11.5 feet. Reclamation performed risk analyses finding the dam cannot safely pass floodwaters in accordance with Reclamation’s Public Protection Guidelines.

In a solicitation set aside for small businesses, Reclamation seeks bids to remove existing concrete features; excavate the existing dam and dikes embankment; install dam and dike, filter, and gravel drain materials to increase height of dam and dikes; increase the height of the dam with a mechanically stabilized earth wall; construct a new spillway crest structure of cast-in-place concrete; modify and install new dam instrumentation; and construct saddle dikes.

The work is valued at between $10 million and $25 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. R13PS20015 in the “Keyword/Solicitation #” box.

Bids now are due April 5. For information, contact Erik M. Danger, Contract Specialist, Bureau of Reclamation – MP – Regional Office, 2800 Cottage Way, Room E-1815, Sacramento, CA 95825; (1) 916-978-5570; E-mail: edanger@usbr.gov.
