St. Louis River AOC Azcon Slip Sediment Remediation

The U.S. Army Corps of Engineers Detroit District is seeking qualified small business firms to provide comprehensive remedial services at the Azcon/Duluth Seaway Port Authority slip in Duluth-Superior Harbor, Minnesota. The contract involves the construction of a remedial cap over an approximately 2.8-acre area with sediment contamination exceeding cleanup standards. Key tasks include mobilization to the site, installation of a silt curtain, mechanical dredging of sediment, treatment of dredged sediment with 5% Portland cement, transport and disposal at a local landfill, and capping with two layers: dredged material from the Duluth Anchorage Area and an armor stone layer. All work will be supervised, managed, and monitored by ongoing government surveys following each construction phase until demobilization is complete. The anticipated contract is a firm-fixed-price, total small business set-aside with an estimated construction cost between $1 million and $5 million. The NAICS code for this project is 562910, and the size standard is set at 750 employees. The solicitation was expected to be posted electronically in early to mid-June 2020 on the System for Award Management (SAM) website, with no hard copies provided. Interested contractors must self-register in SAM to access the solicitation documents, which include specifications, drawings, and attachments. Points of contact for further information are provided through the Detroit District office, which oversees this Department of Defense project.
