U.S. awards $132 million contract for dam safety cutoff wall at East Branch Dam

The U.S. Army Corps of Engineers awarded a contract to Layne Christensen Co. for dam safety work to construct a deep cutoff wall at East Branch Dam on the East Branch Clarion River in Pennsylvania.

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.

Under a $132.5 million contract, Layne Christensen, of Ruther Glen, Va., is to construct the concrete cutoff wall through the dam and abutments to an expected maximum depth of 260 feet.

The Corps’ Pittsburgh District took bids for the work in October 2013.
