The U.S. Army Corps of Engineers has awarded a US$44.2 million contract to Treviicos South Inc. to construct a dam safety seepage barrier at Ohio’s Bolivar Dam.
The Corps’ Huntington, W. Va., District most recently sought bids for the work this past August.
Bolivar Dam is an 87-foot-tall, 6,300-foot-long embankment on Sandy Creek, a tributary of the Tuscarawas River.
Per the contract, Treviicos will construct a partial depth seepage barrier of 4,500 feet in length and 145 in depth through the upstream slope of the dam embankment terminating in the left abutment. Work will also include a grout curtain of 329 feet in length and 60 feet in depth in the left abutment from the end of the seepage barrier to near the emergency spillway.
HydroWorld.xcom reported the Corps awarded a $4.7 million contract in 2012 to TAB Construction Co. Inc. to install six service gates and rehabilitate gate works at the dam.
