The Department of Defense, specifically the U.S. Army Corps of Engineers, is seeking qualified contractors to design and build an automated casting facility at Richardson Landing, Tennessee, aimed at producing articulated concrete mattress (ACM) squares for channel stability along the Lower Mississippi River. The facility must be capable of producing a minimum of 50,000 ACM squares annually, with scalability to 150,000 squares through multiple shifts, while ensuring year-round operations that are independent of weather conditions. This initiative is critical as the ACM squares play a vital role in maintaining channel stability, and the project aims to modernize the casting process, enhance efficiency, and uphold stringent quality standards, including a compressive design strength of 3,000 psi. Interested firms must submit a capabilities package detailing their relevant experience and execution strategy by 12:00 PM CST on October 22, 2024, to Kirk A. Middleton at kirk.a.middleton@usace.army.mil, with no reimbursement for costs incurred in response to this announcement.
