SOUTHERN CONTRACTING, LLC

Southern Contracting, LLC specializes in heavy civil infrastructure construction with deep expertise in water and sewer system rehabilitation, seepage remediation, and utility modernization for federal installations. The contractor delivers complex hydraulic and sanitary infrastructure projects, including sewer line replacements, lift station installations, backflow prevention upgrades, and water treatment plant expansions. Their technical proficiency extends to seepage control, pavement milling and overlay, and civil earthwork for military and federal sites, demonstrating strong command of subsurface utility coordination, stormwater management, and infrastructure resilience standards. A key differentiator is their ability to execute mission-critical utility upgrades under stringent operational constraints, often in active defense installations with minimal disruption. The company maintains a consistent and primary relationship with the Department of Defense, delivering mission-supporting civil works across multiple installations, including sewer system overhauls, road surface rehabilitation, and facility upgrades. Their work for the Department of the Interior reflects a complementary capability in public land utility rehabilitation, particularly in parkwide infrastructure modernization. These engagements suggest a trusted partner status for agencies requiring reliable, on-site execution of aging infrastructure renewal under federal compliance frameworks. Southern Contracting’s industry focus centers on NAICS 237110 (water and sewer line construction) and 237990 (other heavy and civil engineering construction), where they execute precision civil works involving underground utilities, drainage systems, and structural remediation. Their market positioning is that of a niche civil contractor with specialized experience in military and federal utility resilience, particularly in water infrastructure modernization and environmental compliance projects. As a small business structured as a 2L entity based in Biloxi, Mississippi, Southern Contracting, LLC operates with regional agility while serving national defense and federal land management priorities. The firm holds no federal certifications but leverages localized expertise and proven field performance to secure repeat engagements on mission-critical infrastructure projects.
