This is a solicitation document and associated project drawings for maintenance dredging work issued by the U.S. Army Corps of Engineers, New Orleans District.

The solicitation (W912P826BA015) covers maintenance dredging of approach channels for the East and West Calumet Floodgates and Bayou Teche in St. Mary Parish, Louisiana. The project involves excavating material from two separate channels to specified depth requirements: elevation -8.0 Mean Low Gulf (MLG) from station 0+00 to 0+50, and elevation -9.0 MLG from station 0+50 to the dredge limit. The West Calumet channel extends approximately 575 feet with dredging limits at station 5+75, while the East Calumet channel extends approximately 580 feet with limits at station 5+80. Channel widths are 66-107 feet and 42-107 feet respectively. All excavated material shall be placed beyond the -35 foot contour in Wax Lake Outlet. The contract includes timber guide wall structures, pile clusters, link fencing, and chain fence configurations at both locations. Vertical control is referenced to a staff gage at the East Floodgate with gage zero at 0.0 feet NGVD (National Geodetic Vertical Datum) equal to +0.78 feet MLG. The project documents include plan and profile views, typical cross sections at multiple stations, and detailed identification sheets with design approvals from the Civil Branch, Engineering Division, and District Commander. The anticipated contract number format is W912P826CXXXX, with a solicitation date of June 2025.
