U.S. seeks drain system rehab construction at 517.8-MW Garrison

The U.S. Army Corps of Engineers seeks bids for construction work to rehabilitate the drainage system of the powerhouse and west terrace at 517.8-MW Garrison Dam on the Missouri River in North Dakota. Bids are due Aug. 9.

The Corps’ Omaha District previously took bids to rehabilitate spillway gates at Garrison and 786-MW Oahe Dam. The Corps said in April that it expects to solicit a large volume of contracts to repair 2011 flood damage in the Missouri River Basin, including work affecting Garrison, Oahe, and four other major Corps hydro projects.

In a solicitation restricted to small businesses, the Corps now seeks bids for the drain system work, including replacing manholes, catch basins, sub-drains, and observation risers in addition to installation of eight relief well outfall pipes within the switchyard and powerhouse cut-slopes at Garrison. The contractor also will be required to hydro-flush selected drain segments, provide visual inspection with remote-operated camera equipment, and provide a detailed formal report documenting findings.

The work is valued at between $1 million and $2.5 million.

A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W9128F12R0052 in the “Keyword/Solicitation #” box.

Bids are due Aug. 9. For information, contact Brandy R. Eaves, U.S. Army Corps of Engineers, Omaha District, 1616 Capital Ave., Omaha, NE 68102-4901; (1) 402-995-2089; E-mail: brandy.r.eaves@usace.army.mil.
