The U.S. Army Corps of Engineers continued to extend the bidding deadline for dam safety work to construct a deep cutoff wall at East Branch Dam on the East Branch Clarion River in Pennsylvania. Bids now are due Sept. 27.
The Corps' Pittsburgh District previously called for bids Sept. 25, Aug. 29, Aug. 19, July 19, and June 21.
The rolled earthfill embankment has experienced seepage problems that required repairs in 1957. It has been determined to be potentially unsafe, prompting the Corps to take precautionary measures pending implementation of a dam safety modification program.
The Pittsburgh District took comments in November on a draft request for proposals for the work. It also invited contractors in March 2012 to present their capabilities to construct the concrete cutoff wall through the dam and abutments to an expected maximum depth of 260 feet.
The Corps now seeks bids to perform the work, which is valued at $100 million to $250 million.
A solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering solicitation No. W911WN13R0002 in the "Keyword/Solicitation #" box.
Bids now are due by 11 a.m., Eastern time, Sept. 27. For information, contact Donna Yon, Contract Specialist, U.S. Army Corps of Engineers, Pittsburgh, 1000 Liberty Ave., 22nd Floor, Pittsburgh, PA 15222-4186; (1) 412-395-7549; E-mail: firstname.lastname@example.org.
