Duraserv LLC

Duraserv LLC, operating as Southern Dock, is a for-profit limited liability company based in Carrollton, Texas, that supplies and installs loading dock equipment—dock levelers, overhead doors, coiling doors, and steel stairs—to federal agencies as a prime contractor (59% of recent awards) and as a subcontractor on federal construction and facility renovation projects. The vendor competes on full-and-open procurements with no set-aside designations and operates as a subsidiary parent with Southern Acquisitions, LLC.

Duraserv's capability portfolio centers on procuring and installing specialized loading dock and facility access equipment. Representative prime work includes a $113,754 firm fixed-price purchase order from the Air Force Global Strike Command (July 2022) for dock levelers; two inside and outside dock leveler purchase orders totaling $31,198 from the Department of Justice Bureau of Prisons Federal Correctional Complex Yazoo City (November 2023–March 2024) for food service operations; a $44,630 Office of Naval Research purchase order (June 2025) for overhead door replacement at Naval Research Laboratory Key West; and a $48,387 National Institute of Standards and Technology purchase order (September 2026) for steel collapsible and standard stairs with installation, mechanical training, and one-year warranty at the NIST Campus in Gaithersburg, Maryland. All prime awards are firm fixed-price purchase orders with no set-aside designations, reflecting the commodity nature of the work.

Customer concentration is moderate and distributed across federal facility and defense customers. The vendor has worked with 17 distinct customer agencies across 22 awards. The top five customers by award count account for 45% of all awards, led by the Department of Justice Bureau of Prisons Federal Correctional Complex Yazoo City, the Department of Veterans Affairs Veterans Health Administration, the Department of the Navy Installations Command, the Office of Naval Research, and the Army Corps of Engineers. However, the dollars ranking diverges slightly: the top five by potential value (74% of combined value) are led by the Air Force Global Strike Command ($114 thousand), followed by the Office of Naval Research ($54 thousand), the National Institute of Standards and Technology ($48 thousand), Veterans Affairs ($39 thousand), and Naval Air Systems Command ($37 thousand). The Air Force account anchors the largest single award but represents only one transaction; Navy and DOJ accounts offer deeper engagement with multiple smaller orders.

Duraserv places work under a fragmented vehicle portfolio across service-contract and construction MATOCs: the Southeast Area of Responsibility Multiple Award Construction Contract (2 task orders), the Tyndall Air Force Base Reconstruction MATOC, the North Region Small Business MATOC (Mobile District AOR), a Corps of Engineers Multiple Award Construction Contract North Florida South Georgia, and the indefinite-delivery contract 70Z04718DRQAECM00. These vehicles are smaller, regionally focused, or specialized-purpose IDVs rather than government-wide platforms.

Activity has been episodic. Five awards were placed in 2023, four in 2025, two in 2026, and only one in 2024, with five total from 2016–2022. Combined potential value across all awards is $394 thousand, but combined obligated dollars reach $2 million—a 508% ratio that signals that purchase-order ceilings are conservative relative to actual performance spending. Only one award (the NIST stairs order, $48 thousand) reaches ultimate completion within the next twenty-four months, limiting near-term recompete exposure.

In its subcontractor role, Duraserv delivers overhead door supply, installation, and removal services under general construction and facility renovation primes. Named subs since 2023 include RQ Construction LLC (two overhead-door orders for Naval Submarine Base Kings Bay hurricane repairs and magnetic silencing facility work, October 2025–January 2025); BL Harbert International LLC (overhead coiling doors for WEG maintenance hangar design-build and SS009 faucets and valves work, December 2023–February 2023); The Clement Group LLC (ACV landing-craft support facility overhead doors, March 2023); Koman Construction LLC (Tinker Air Force Base overhead door renovation, May 2024); Southeast Cherokee Construction Inc. (Building 550 HVAC and mold remediation turnkey overhead door, October 2025); and Rq-Aecom 2 JV (Key West Rebuild Section Station garage door installations, May 2026). The sub footprint is heavily weighted to Navy and Air Force facility work executed through regional construction and renovation contractors.

The Service Contract Inventory dataset captures only two records as named subcontractor across FY2024–FY2025, with zero full-time equivalents reported, reflecting that SCI tracks service contracts above the $150,000 threshold and excludes goods and products. Duraserv's federal revenue footprint is dominated by equipment sales and installation purchase orders below or at the reporting threshold—not labor-intensive services—making SCI an incomplete view of the vendor's federal activity.
