The U.S. Army Corps of Engineers, Huntington District, issued a Notice of Award to TREVIICOS (TREVI Division) for the Major Rehabilitation of Bolivar Dam in Ohio. In the western State of Wyoming, the subsidiary TREVIICOS was also awarded a contract for the construction of cut off walls for a new dam for a mining complex near Green River.
The Bolivar Dam project will consist of the construction of a seepage barrier approximately 4,500 ft. (1,372 meters) in length and a maximum depth of 144 ft. (44 meters) through the upstream slope of the dam embankment along the left abutment. Drilling and grouting along an alignment approximately 300 ft. (91 meters) in length by 60 ft. (18 meters) average depth in the left abutment of the dam from the end of the seepage barrier to near the emergency spillway is also required as part of the project. The containment barrier will be installed using Soilmec’s special equipment which will ensure the best technology for the works. The seepage barrier shall be a minimum of 24 inches (0.6 meters) wide through the entire length and depth and shall be continuous and homogeneous.
The CEO of TREVI Group Stefano Trevisani commented: “We are very pleased with these acquisitions and in particular with the new order from the U.S. Army Corps of Engineers. The Bolivar Dam, in the State of Ohio, is overall the sixth complex work commissioned to the Group and confirms the confidence placed in the excellence of execution of TREVI. TREVIICOS was awarded the Project within a complex tender which carefully considered both the economic offer and the technical solution selected for the project. This announcement, along with the recent acquisitions of the last few weeks, continues to show the clear trend of improvement of the international infrastructure sector."
