About this file

Written by GovTribe AI · Jun 12, 2026

This document is a set of design drawings and specifications for a federal dredging contract issued by the U.S. Army Corps of Engineers, New Orleans District.

The solicitation (W912P826BA015) covers maintenance dredging of approach channels to the East and West Calumet Floodgates on Bayou Teche in St. Mary Parish, Louisiana. The work involves dredging two separate channels to required grades of elevation -8.0 MLG (Mean Low Gulf) from station 0+00 to 0+50, and -9.0 MLG from station 0+50 to the dredge limit at approximately stations 5+75 (West Calumet) and 5+80 (East Calumet). The West Calumet channel maintains dimensions of 66 feet wide with 40-foot side slopes, while the East Calumet channel maintains 42 feet wide with 40-foot side slopes. Excavated material must be placed beyond the -35 foot contour in Wax Lake Outlet as the designated disposal area. The contractor is required to note that channel dimensions transition both vertically and horizontally in the plan and profile views. The project includes existing conditions surveys dated October 2025 and vertical control referenced to a staff gage on the East Floodgate wall with gage zero at 0.0 feet NGVD (National Geodetic Vertical Datum). The design was completed in June 2025 with contract number W912P826CXXXX and includes detailed cross-sectional profiles at multiple stations showing existing grades and required dredge templates for both floodgate approach channels.
