DFI 2013 OUTSTANDING PROJECT AWARD

This year’s OPA will be presented to representatives of both the U.S. Army Corps of Engineers (USACE) and the Treviicos-Soletanche Joint Venture (TSJV). The project was nominated by the two organizations, making it a double winner.

Wolf Creek Dam is on the Cumberland River in south central Kentucky. The dam and its adjacent reservoir reside upon a heavily Karst bedrock foundation. The USACE placed the dam under a 'high risk' for failure designation and launched a $584 million major rehabilitation program. The dam was plagued by leaks and repaired many times before the successful engineering solution was completed.

The main contract was awarded in 2008 to Treviicos-Soletanche Joint Venture for the construction of a 980,000 sf concrete barrier. The concrete barrier wall was built using eight different techniques including: high mobility grouting, low mobility grouting, clamshell excavation, hydromill excavation, directional drilled pilot holes, auger drilling, reverse circulation drilling and verification coring drilling.
