About Southern Dredging Co Inc.

Southern Dredging Co Inc. is a small business subchapter S corporation headquartered in Charleston, South Carolina, that specializes in maintenance dredging services throughout the southeastern United States. Registered in the System for Award Management since November 2001, the company brings extensive experience executing dredging operations at critical maritime infrastructure including military installations, commercial ports, and navigable waterways. Southern Dredging Co Inc. has established itself as a trusted federal contractor primarily serving the U.S. Army Corps of Engineers across multiple districts, with a demonstrated track record of performing complex maintenance dredging projects involving sediment removal, material placement, and environmental compliance.

Southern Dredging Co Inc. has provided maintenance dredging services through numerous prime federal contract awards totaling over $72 million since 2021. The company's contract work encompasses dredging operations at key southeastern maritime facilities including Naval Submarine Base Kings Bay in Camden County, Georgia; Joint Base Charleston in South Carolina; Charleston Upper Harbor; Brunswick Inner Harbor in Georgia; Wilmington Harbor in North Carolina; and multiple Atlantic Intracoastal Waterway selective sites. All prime federal contract awards to Southern Dredging Co Inc. have been designated as Total Small Business Set-Asides, reflecting the company's small business status and the government's commitment to utilizing small business contractors for critical infrastructure maintenance. The company's contracts typically involve the removal of accumulated sediment ranging from 500,000 to over 3 million cubic yards, placement of dredged materials in designated confined disposal areas or upland sites, and environmental compliance activities such as bird monitoring and timing restrictions to protect endangered species. The U.S. Army Corps of Engineers, through its various districts including Savannah, Charleston, Jacksonville, and Wilmington, has been the primary funding agency for Southern Dredging Co Inc.'s contract awards, with individual contract values ranging from approximately $2.3 million to $14.4 million and performance periods typically spanning six to eighteen months.

Southern Dredging Co Inc. currently holds a single-award Indefinite Delivery Contract (IDC) valued at $400,000,000, awarded by the U.S. Army Corps of Engineers Jacksonville District on June 11, 2025, with a period of performance through July 16, 2030. This base year contract establishes a multiple award task order contract (MATOC) pool framework to provide maintenance dredging and surface cleanup activities within the boundaries of the USACE South Atlantic Division under NAICS code 237990, with anticipated task orders ranging from $1,000,000 to $25,000,000. The IDC is set aside for total small business participation and will support the USACE's mission to maintain navigable waterways for both commercial and military vessel operations at strategic southeastern locations including Naval Submarine Base Kings Bay, Joint Base Charleston, and Wilmington Harbor. Although the contract is structured as a MATOC with multiple award intentions, Southern Dredging Co Inc. has secured the initial single award, positioning the company as a primary provider for maintenance dredging services across the South Atlantic Division through the contract's five-year performance period.
