Maintenance Dredging of Flushing Bay and Creek, New York, Federal Navigation Project.

The Maintenance Dredging of Flushing Bay and Creek, New York, Federal Navigation Project is a Department of Defense initiative managed by the US Army Corps of Engineers, New York District. Under solicitation W912DS22B0012, the project involves removing approximately 150,000 cubic yards of material, primarily consisting of silt and clay, to achieve a depth of -15 feet Mean Lower Low Water plus 2 feet of allowable overdepth. Due to environmental restrictions and water quality certificates from the New York State Department of Environmental Conservation, the work must be performed using a mechanical clamshell dredge equipped with an environmental bucket, supported by multiple scows and tugboats for dredging, dewatering, and unloading operations. The project magnitude is estimated between 10 million and 25 million dollars, with the dredged material being transported to state-permitted upland sites in compliance with all federal, state, and local regulations. Technical specifications include detailed sounding maps, channel coordinates, and sediment analysis for volatiles and semivolatiles to ensure safe placement. The procurement process involved a sealed bid invitation with a response deadline in June 2022, incorporating specific heavy dredging wage determinations and a structured bid schedule for mobilization and dredging activities.
