WOLF CREEK DAM BARRIER WALL CONTRACT AWARDED FOR USD 341,4 MIL.

Cesena, 24 July 2008_ The U.S. Army Corps of Engineers, Nashville District, announced that a contract in the amount of $341.4 million has been awarded to Treviicos Soletanche JV. Treviicos is the sponsor of the joint venture in which it has a 50% interest.

Scope of the work is the installation of a concrete barrier wall at Wolf Creek Dam in Russell County, Kentucky. Work is expected to begin this fall with a contract performance period of four years.

The concrete barrier wall is the primary element of the Wolf Creek Dam Seepage Rehabilitation Project. The wall will be a combination of secant piles and rectangular panels installed through the earthen embankment to a depth of about 275 feet. It will go deep into the foundation rock to effectively cut off seepage through the limestone. The wall will extend eastward along the upstream embankment from the concrete section to the right abutment, a length of about 4,200 feet.

The Trevi Group Managing Director Mr Stefano Trevisani has declared that this award is a major achievement for Trevi Group:
- The contract amount is the largest in our 50 years Company history.
- Trevi Group received in the last few months from USACE two other contracts referring to the extention of Tuttle Creek Dam Rehabilitation Program and to maintenance works for Herbert Hoover Dike for a total amount of $97 million; our total backlog in the USA is now around $300 million. These acquisitions place Trevi Group in a strong position with reference to relevant future projects with USACE related to infrastructure works.
- Trevi Group is strongly supported in its USA activities by major American financial institutions.
- We are pleased of the cooperation with Soletanche-Bachy, a company with whom we have a long tradition of partnering.
