U.S. awards dam safety site stabilization at 270-MW Wolf Creek Dam

The U.S. Army Corps of Engineers awarded a $950,088 contract to Aspen Construction Co. for dam safety site stabilization work at 270-MW Wolf Creek Dam in Kentucky.

The Corps’ Nashville District took bids for the work in June.

Aspen, of Hackensack, Minn., is to perform site stabilization at the hydropower project including downstream berm regrading, a trench drain system, tailwater piping removal, and excavation and disposal area seeding.

Identifying the earthfill and concrete gravity dam as critically near failure or having extremely high life or economic risk, the Corps awarded dam safety contracts in 2011 for a grout curtain and in 2013 for geotechnical engineering. Also in 2013, the Corps poured the last of 1,200 concrete piles required to mitigate seepage through the karst geology deep in Wolf Creek Dam’s foundation.
