Y--Center Hill Remediation Dam Rehabilitation

The Government has awarded contract W912P5-11-C-0014 to the Department of Defense, specifically through the Endist Nashville office, for the continued rehabilitation of the Center Hill Dam foundation near Lancaster, Tennessee. The primary objective of this project is the construction of a concrete seepage barrier wall at the main dam embankment, which will extend from elevation 696 down to approximately elevation 405 msl. This barrier is designed to penetrate both the existing earthen embankment and the underlying limestone bedrock. Due to the high compressive strength of the limestone foundation, which averages 16,000 psi and reaches up to 40,000 psi, the project utilizes a combined construction method featuring hydromill and circular pile elements. Additionally, a concrete encasement wall will be implemented to ensure the protection of the earthen embankment throughout the construction process. The work is categorized under NAICS code 237990.
