About this opportunity
The U.S. Army Corps of Engineers New Orleans District is soliciting proposals for a cutterhead dredging contract to construct and potentially maintain a saltwater barrier sill on the Mississippi River between Mile 63.0 and Mile 64.0 Above Head of Passes. The work involves hydraulically placing dredged material from designated borrow areas on the river bottom to build the sill structure, which may require construction to -30' Low Water Reference Plane with a 620' notch to -55' LWRP. Contractors must provide a cutterhead dredge with a minimum 30-inch inside diameter discharge pump and maintain minimum production rates of 3,415 cubic yards per hour in Borrow Area #1, while complying with extensive technical specifications for equipment, surveying, environmental protection, and safety requirements. The solicitation was posted on July 22, 2025, with bids originally due on September 18, 2025, though an amendment established the bid opening for September 22, 2025. The contract award was ultimately made to Weeks Marine, Inc. for $31,460,000.
This solicitation does not utilize any set-aside designations and is unrestricted to all qualified contractors. Weeks Marine, Inc. was awarded the contract with a total value of $31,460,000, which exceeds the initially estimated construction range of $10-25 million. The contract includes a base work package of 350 dredging hours valued at $7,124,900, with multiple options adding additional 400-hour increments and supplementary services including mobilization/demobilization, interim mobilization, standby services, and dredge towing. The work will be performed in Louisiana waters along the Mississippi River, specifically in the designated area between the specified mile markers Above Head of Passes. Key contract personnel include Cori Caimi as the Contract Specialist and Shaun McAfee as the Contracting Officer, both from the U.S. Army Engineer District in New Orleans.
