The Department of Defense, through the Army Corps of Engineers, is conducting a market survey to identify small business concerns interested in a project to install articulated block on the abutments of the Patoka Lake Main Dam in Dubois, Indiana. The project entails the removal of concrete rubble, filling undermined areas, and the installation of flexible matting, requiring experience with vegetated concrete block matting due to the presence of shallow bedrock. The estimated contract duration is 180 calendar days, with a projected cost range between $250,000 and $500,000, and interested small businesses must respond by November 21, 2024, with required documentation to Kelly Duggins at Kelly.S.Duggins@usace.army.mil.
