The U.S. Army Corps of Engineers seeks bids for exploratory foundation grouting at 54-MW Dale Hollow Dam on the Obey River in Tennessee. Bids are due Aug. 31.
Dale Hollow is among nine Corps hydroelectric projects on the Cumberland River system that require rehabilitation and upgrading.
In a solicitation set aside for small business, the Corps’ Nashville District seeks a 250-foot-long line of borings drilled to a depth of about 85 feet into the foundation adjacent to an active switchyard on the right bank of the Obey River. Overburden thickness varies from 2 to more than 30 feet. Drilling will be followed by setting 3-inch, schedule 40 PVC casing. Systematic stage grouting of the bore holes will be a significant component of the work, but the primary purpose of the contract will be investigative.
The work is valued at $1 million to $5 million.
A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912P512B0009 in the “Keyword/Solicitation #” box.
