Brayman Construction Corporation, a leading general and specialty foundation contractor in Saxonsburg. Pa., is finishing up work on the $96 million Charleroi Locks and Dam project on the Monongahela River. Working with the Trumbull Corporation. Brayman constructed portions of a new river wall. The work included "in-the-wet" construction techniques for drilled shafts and mass concrete placement, as well as construction of a disposal facility and concrete batch plant, which will be turned over to the U.S. Army Corps of Engineers upon completion of the project.

After stabilizing the existing downstream river wall. the contractors performed underwater excavation along the length of the new river wall and drove sheet pile cutoff walls for the new river monoliths. Workers installed 78-inch-diameter drilled shaft foundations for the monoliths and placed concrete for the monoliths using tremie methods. Each monolith required three lifts of 15 feet.

Recently completed river projects include emergency erosion repair of the dam at Allegheny River Lock 6. construction of 17 sheet pile cells of various diameters for a new barge unloading facility at the Cardinal Power Station, just south of Steubenville. Ohio. and construction of the award-winning Kanawha River Bridge at Charleston. W.Va.

The bridge has an overall length of  2.975 feet and its main span is the longest continuous segmental span in the U.S. Completed in September 2010. it was recognized as the No. 1 Bridge for 2009 by Roads and Bridges magazine.
