Final concrete placements complete Center Hill Dam barrier wall
Members of the U.S. Army Corps of Engineers Nashville District and Bauer Foundation Corporation are concentrated in the center of the work ramp up March 17, 2015 to watch the last concrete placement of the Center Hill Dam Remediation Project at Lancaster, Tenn. The Corps of Engineers and its Contractor Bauer Foundation Corporation installed a 2.5-feet thick concrete barrier wall vertically along the embankment in overlapping rectangular columns as deep as 308 feet from the top of the dam deep into the solid-rock foundation. The placement completes the $115 million foundation barrier wall project that began July 11, 2012. Enough concrete was placed into the embankment to build a four-foot wide sidewalk 200 miles or about the distance between Nashville and Knoxville in Tennessee.
