About Southland Industries
Southland Industries' Mid-Atlantic Division operates as a large for-profit mechanical, electrical, and plumbing (MEP) contractor delivering emergency facility repairs, HVAC maintenance, energy efficiency upgrades, and infrastructure modernization to federal agencies, predominantly as a prime contractor (94% of awards) competing full-and-open across civilian and defense customer bases.
Southland Industries is headquartered in Sterling, Virginia, with a parent company structure that includes the subsidiary Envise. The vendor has held federal contracting authority since 2003 and competes without set-aside designation. The company's primary NAICS footprint sits in electrical contracting (68 awards) and plumbing, heating, and air-conditioning contracting (13 awards), with secondary exposure in engineering services (7 awards). The capability portfolio reflects MEP facility infrastructure work: emergency HVAC repairs, ductwork installation and renovation, mechanical controls integration, energy savings performance contracting, and facilities management across federal properties.
Customer concentration is heavily skewed toward energy and infrastructure modernization. The Department of the Army Corps of Engineers Engineering Support Center Huntsville accounts for 99% of combined potential value across the award portfolio, driven by two Energy Savings Performance Contract II (ESPC II) vehicles totaling $1.66 billion in potential value. Recent representative work includes a $15 million delivery order under ESPC III to the Army Corps of Engineers Engineering and Support Center for Fort Bliss facility improvements extending through July 2046, a $15,379 purchase order from the Department of the Interior Fish and Wildlife Service Region 2 for emergency HVAC repairs at the Aransas Matagorda Island National Wildlife Refuge in Texas (February 2026), and an $11,766 purchase order for emergency HVAC repairs at the Matagorda Island National Wildlife Refuge Visitor Center (July 2025). By award count, secondary customers include the Department of Veterans Affairs Veterans Health Administration (5 awards), the Consumer Product Safety Commission (4 awards), and the Naval Sea Systems Command (4 awards), though these carry minimal dollar value in comparison.
Southland's vehicle position reflects the ESPC II anchor: the Federal Supply Schedule GS06F0087R carries 66 task orders valued at $2.5 million, the ESPC II vehicles account for $126.2 million across two task orders, and the Seaport Next Generation vehicle hosts four task orders. The company holds a GSA Multiple Award Schedule contract (March 2025, valid through March 2030, $700,000 ceiling) covering SIN 334512 for facilities management systems and SIN 541690E for energy services, with an eight-category labor portfolio spanning administrative support through senior project management at rates from $86.45 to $172.90 per hour, all non-cleared roles with education requirements from high school through bachelor's degree.
Recent activity shows growth: one award in 2017, two in 2023, two in 2024, five in 2025, and one to date in 2026. The combined potential value across 93 awards totals $1.69 billion, though only $53.4 million (3%) has been obligated. Service Contract Inventory data covering FY2022–FY2024 shows SCI-reportable invoicing of $3.8 million as a prime contractor across four prime records, with the vendor deploying 0.7 FTEs in FY2022, 1.5 FTEs in FY2023, and 5.3 FTEs in FY2024 on SCI-captured work. Government-paid rates on prime contracts ran from a 10th percentile of $61.96 per hour through a median of $289.23 per hour to a 90th percentile of $803.53 per hour, reflecting the mix of technician-level and senior engineering labor. Across SCI-reportable prime contracts, subcontractors performed 17% of total contractor hours, with one named subcontractor reported.
In its subcontractor role, Southland performs HVAC support and mechanical work on four awards under Eastern Research Group Inc., including HVAC technician and technician support to Naval Surface Warfare Center Indian Head Division (July 2024 and October 2024), hydrant flow testing support (August 2025), and design engineering and project management for DOD weapon systems energetics manufacturing (October 2025). Southland also subcontracts to Cheroenhaka Nottoway Enterprises on a Design/Build renovation at the Food and Drug Administration's Silver Spring facility (September 2023) and to an entity listed as M.c. Cleansvendornametrait.phpdean, Inc. on medium-voltage power generation recapitalization at Buckley Space Force Base, Colorado (January 2025).
