The company's contract portfolio demonstrates a concentrated focus on Atlantic Intracoastal Waterway maintenance dredging across North Carolina and Florida, utilizing hydraulic cutter suction dredging equipment to remove shoaled materials and maintain navigational depths of 8 to 12 feet. All contracts reviewed carry total small business set-aside designations, reflecting the company's qualification and preference in the federal procurement process. Recent awards include a $11.45 million contract (November 2025) for maintenance dredging between Currituck County and Brunswick County in North Carolina, a $7.23 million contract (October 2025) for operations at St. Lucie Inlet and Jupiter Inlet in Florida, a $3.1 million contract (September 2025) for the Naples to Big Marco Pass channel in Florida, and a $12.1 million contract (November 2024) for the Atlantic Intracoastal Waterway between Wilmington and Ocean Isle Beach in North Carolina.

Beyond dredging excavation, Southwind Construction Corp's contracts require environmental monitoring services including endangered species surveys, turbidity monitoring, vibration monitoring, and beach tilling operations. The company strategically places dredged materials on approved ocean beaches, bird islands, upland placement areas, and inshore impoundment basins, with work often subject to environmental placement windows restricting beach operations to specific seasonal periods. All contract awards have been issued through the Civil Works division of the U.S. Army Corps of Engineers, with primary execution through the Jacksonville and Wilmington Districts.
