Control Southern Inc.

Control Southern Inc., a for-profit small business based in Suwanee, Georgia, operates as a prime contractor (91% of recent awards) and occasional subcontractor delivering machinery health monitoring equipment, industrial valve services, and equipment maintenance and repair to federal agencies across defense and civilian customer bases. The vendor competes full-and-open without set-aside designations across its prime footprint.

Control Southern's customer base concentrates heavily on the Tennessee Valley Authority, which accounts for 37 of 56 total awards in the source data. Among federal agencies, the Department of the Navy Naval Air Systems Command leads by potential value at $590 thousand across four awards, followed by the Department of Veterans Affairs Veterans Integrated Service Network 9 at $152 thousand across two awards, and the U.S. Fleet Forces Command (Atlantic) at $81 thousand. The concentration diverges sharply between award count (TVA dominance) and dollar value (Navy-led federal agencies), reflecting TVA's high-frequency small-order pattern versus federal agencies' larger but fewer procurements. NASA Kennedy Space Center and NASA Marshall Space Flight Center round out the top five by award count with four and two awards respectively.

Capability work centers on industrial valve services, equipment maintenance, and instrumentation. Representative prime awards include a $63,360 sole-source purchase order from Naval Air Systems Command (June 2026) for one-year maintenance and software support of AMS Machinery Manager Software and CSI 2140 Four-Channel Machinery Health Analyzers with four optional renewal periods extending through June 2031; a $146,001 firm fixed-price purchase order from VA Veterans Integrated Service Network 9 (September 2025) for Emerson Delta V equipment service running through September 2030; and a $44,563 purchase order from U.S. Fleet Forces Command (May 2025) for an AMS 2140 Health Analyzer. Top NAICS categories include Industrial Machinery and Equipment Merchant Wholesalers (3 awards), Research and Development in Physical, Engineering, and Life Sciences (3 awards), and Plumbing, Heating, and Air-Conditioning Contractors (2 awards). PSC codes reflect valve-heavy scope: Maint/Repair/Rebuild Of Equipment—Valves (13 awards), Valves Nonpowered (10 awards), and Valves Powered (7 awards). In its subcontractor role, Control Southern supplies materials and components to Defense Systems and Solutions on a C-130 IMAFFS unit prototype effort at Redstone Arsenal, to Amentum Services on Kennedy Space Center valve procurement, and to unnamed primes on NASA's COMET (Consolidated Operations, Management, Engineering, and Test) contract modifications.

Activity has been sparse and episodic: one award in 2019, two in 2021, four in 2024, two in 2025, and three in 2026. Combined potential value across all awards totals $890 thousand, though combined dollars obligated reach $2.7 million (298% of potential value), indicating invoice performance substantially exceeding contract ceilings. The vendor holds positions on two indefinite delivery contracts but places minimal task-order activity under them.
