A $10.3 million dam rehabilitation project in Grant County, W.Va., is well past the halfway point.
The project involves New Creek Site 14. Notice to proceed was issued in January 2011, and the contract completion date is currently set for March 2013. The original contract amount was reportedly $9.6 million, but with contract modifications and variations in estimated quantities, the final contract amount is estimated to be approximately $10.3 million.
The funding for the project is 65 percent federal and 35 percent local, with local sponsors being Potomac Valley Conservation District; the city of Keyser, W.Va.; and the West Virginia State Conservation Committee.
The prime contractor is Heeter Construction Inc. of Spencer, W.Va., where Dave Heter serves as president. The most significant subcontractor is ASI Constructors Inc. from Pueblo West, Colo., the company responsible for Roller Compacted Concrete (RCC) and reinforced concrete placement.
“The rehabilitation project includes many of the elements involved in the rehabilitation of an existing embankment structure,” said Carol Lagodich, public affairs specialist of the West Virginia State Office of the USDA Natural Resources Conservation Service (USDA-NRCS). “USDA-NRCS has assisted with the design and construction of 170 dams in W.Va. However, this project is the first rehabilitation of a dam by NRCS in West Virginia.”
The contract calls for the rehabilitation of the flood control and water supply dam, which includes flattening both the upstream and downstream slopes to improve stability of the embankment, installation of an internal filter and drainage system in the downstream slope of the embankment, replacement of the upstream riser intake structure, and construction of an (RCC) stepped-chute auxiliary spillway.
