Hsg, LLC

Herndon Solutions Group, LLC (doing business as Hsg, LLC), a woman-owned small business based in Merritt Island, Florida, delivers environmental compliance, occupational health, and technical services to federal agencies as a prime contractor (98% of recent awards) under environmental and medical contracts, indefinite delivery vehicles, and GSA Schedules. The company operates predominantly in full-and-open competition, with select awards under Total Small Business set-asides.

The vendor's customer footprint concentrates heavily with space and environmental agencies. NASA Kennedy Space Center anchors the portfolio by potential value—27 awards carrying $347.3 million combined ceiling—while the Department of Interior Bureau of Land Management National Office ranks second with 45 awards valued at $39.9 million combined. Air Force Space Command's Space and Missile Systems Center places 48 awards with $2.2 million potential value. These five customer organizations account for 65% of recent awards and 84% of combined potential value. NASA Langley Research Center (29 awards, $14.7 million) and EPA Region 9 (8 awards, $16.3 million) round out the major customers by dollar magnitude.

Hsg's capability portfolio spans environmental site assessments, Phase I and II investigations, CERCLA remediation support, occupational health and medical services, environmental baseline surveys, water sampling and analysis, industrial hygiene, health physics, and hazardous materials management. Representative work includes a $10.5 million NASA task order for environmental and occupational health program services at John C. Stennis Space Center through September 2030; a $19.7 million delivery order from NASA Marshall Space Flight Center for occupational health services including occupational medicine, employee assistance programs, industrial hygiene, health physics, and respiratory protection through September 2026; a $4.28 million NASA Langley task order for environmental support services through September 2025; and a $473,196 BLM technical support call for the Fairplay Landfill through March 2028. The vendor also holds a $321.5 million NASA Environmental and Medical Contract (NEMCON), a single-award small business set-aside indefinite delivery vehicle running through 2026, which has generated 111 task orders ($59.5 million combined potential value) across NASA centers and Air Force Space Command facilities at Cape Canaveral and Patrick Space Force Base.

Hsg operates on the GSA Multiple Award Schedule with 34 active labor categories spanning $31.29 to $323.96 per hour, covering roles from Recreation Aide (high school, $31.29/hr) through Principal Manager (master's degree, 10 years experience, $323.96/hr). The spectrum includes mid-tier environmental and engineering specialists—CAD/GIS Technician ($92.84/hr), Engineer Scientist ($124.55/hr), Regulatory Specialist ($136.75/hr)—and senior technical leadership. No security-cleared positions are offered.

Beyond NEMCON, Hsg holds a $7.5 million single-award CERCLA BPA with the U.S. Forest Service Rocky Mountain Region (through October 2028), a $4.9 million multiple-award environmental services BPA with the Department of Interior (through September 2028), and a $151 billion multiple-award IDIQ with the Missile Defense Agency for the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program through December 2035—a significant recent expansion into defense systems integration. The SHIELD vehicle, awarded December 2025, supports research, development, prototyping, systems engineering, and modernization across air, missile, space, and cyber domains, though the initial delivery order is priced at $500.

Activity has contracted in the past two years. The vendor received 46 awards in 2023, declining to 29 in 2024 and 25 in 2025 (with only 5 awards recorded as of July 2026). Twenty-one awards face completion in the next twenty-four months, carrying combined potential value of $24.1 million and therefore exposing the vendor to recompete. SCI-reported invoicing reached $3 million in FY2022 (14.9 FTEs at contract level) and peaked at $11.8 million in FY2023 (38.5 FTEs), with no reportable invoicing in FY2024; these figures represent only federal service contracts above the $150,000 threshold and exclude goods and classified work.

The vendor operates as a prime on 98% of awards and relies on subcontractors for an average 28% share of hours across SCI-reportable contracts, with 13 named subcontractors. Recent sub-award work includes industrial hygiene services and testing on the NASA Space Launch System Mobile Launcher 2 design-and-construction effort under Bechtel National; cybersecurity branch support under General Dynamics Information Technology; and Cape Launch Operations and Infrastructure Support work under Netcentric Technology. SCI-reported government-paid rates run a median of $115.69 per hour, with the 90th percentile at $252.58 per hour, reflecting a mix of technician and senior-level labor delivery.

Hsg's award footprint spans 35 distinct federal agencies across environmental consulting (244 NAICS-classified awards), medical managed healthcare (70 awards), environmental services (69 awards), program management support (37 awards), and natural resources conservation (33 awards). The concentration in environmental and occupational health services reflects the company's core positioning as a provider of compliance, health, and technical support for federal facilities and space operations.
