About this file
This document package includes drawings and specifications for a federal construction contract opportunity with the U.S. Army Corps of Engineers. The scope of work involves removing an existing concrete toe ditch and installing a new toe ditch with reinforced concrete pipe at the Arkabutla Lake Dam in Desoto County, Mississippi. Key aspects of the project include demolishing and removing the existing ditch and pipe, excavating and backfilling, installing relief wells, placing concrete, grouted riprap, graded stone and engineering fabric, and implementing erosion control measures. The pre-bid conference will be held on-site on January 14, 2020 at 10:30 AM with a follow-up site visit. Bids for the W912EE20B0003 solicitation are due in accordance with the specified terms.
