The Deep Foundations Institute (DFI) announces that the Wolf Creek Dam Foundation Remediation Project is the 2013 Outstanding Project Award (OPA).
The award will be presented to representatives of both the U.S. Army Corps of Engineers (USACE) and the Treviicos-Soletanche Joint Venture (TSJV) at the Institute’s 38th Annual Conference, September 25-28, in Phoenix, Ariz. The project was nominated by the two organizations, making it a double winner.
The OPA was established in 1997 to recognize the superior work of DFI members. The project was selected by a committee based on size, scope and challenges of the project, degree of innovation and ingenuity exercised and the uniqueness of the solution to the difficulties of the job.
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.
