About this opportunity
The U.S. Army Corps of Engineers New Orleans District is soliciting bids for maintenance dredging services along the Calcasieu River and Pass in Louisiana, specifically covering Mile 17.0 to Mile 36.0 in Calcasieu and Cameron Parishes. The work involves removing material from the Calcasieu River Ship Channel using hydraulic cutterhead dredging and disposing of it in designated confined disposal facilities adjacent to the river and pass. The base contract includes dredging 3 million cubic yards between Mile 17.0 and Mile 30.0, with optional work extending dredging to Mile 36.0, Devil's Elbow, and Coon Island, plus retention dike construction, surveys, and optional ditching and draining of disposal areas. Contractors must be registered in the System for Award Management (SAM) and comply with specified safety and performance requirements, including precise positioning accuracy and data transmission through the National Dredging Quality Management Program. The original bid deadline was August 26, 2025, at 10:00 AM CT with bid opening at 11:00 AM CT the same day, though Amendment 0001 noted that no further questions would be answered.
This procurement is issued as unrestricted with no set-aside designations and falls under NAICS code 237990 (Other Heavy and Civil Engineering Construction). Six companies submitted bids ranging from $23,439,111 (Muddy Water Dredging, LP) to $72,184,600 (Weeks Marine, Inc.), compared to the government's independent estimate of $51,681,000, indicating significant price variation among bidders. The estimated contract value is between $25 million and $100 million, with a total duration of 280 calendar days for base work plus additional time for optional work items. The channel specifications require a 400-foot bottom width with 1:2.5 side slopes, targeting an elevation of -43 feet Mean Lower Low Water (MLLW). Work will be performed in Louisiana's Calcasieu and Cameron Parishes, with the contractor required to maintain precise environmental compliance and water quality monitoring throughout the dredging operations.
