Salas O'brien Federal, LLC

Salas O'Brien Federal, LLC, a small disadvantaged business headquartered in Katy, Texas, delivers environmental remediation, facilities engineering, and technical services as a prime contractor (99% of recent awards) across the Department of Defense, the Army Corps of Engineers, the National Institutes of Health, and related federal agencies. The firm competes full-and-open, with no set-aside posture recurrent across its prime footprint; one 8(a) sole source award appears in the recent history, but the portfolio is dominated by unrestricted competition. Salas O'Brien Federal is a for-profit limited liability company and parent to three subsidiaries: Sia-Stantec LLC, Techsource LLC, and Sia-Tpmc LLC.

The vendor's capability portfolio centers on environmental systems protection, environmental remediation, environmental consulting, engineering design, facilities support, and low-level radioactive waste handling and transportation. Of 159 recent awards spanning 2016 to September 2026, the top five named award categories (remediation services, engineering services, testing laboratories and services, facilities support, environmental consulting) account for 138 awards across NAICS 541620 (Environmental Consulting Services), 541330 (Engineering Services), 541380 (Testing Laboratories and Services), and related codes. Representative work includes a $44.15 million definitive contract with the Department of the Army (awarded September 2025) for design and construction of an Automated Mat Casting Facility at Richardson Landing, Tennessee, through September 2028; a $6.1 million delivery order from NIH Construction (August 2026) for facilities information management and assessment services under the FY26 A/E MATOC vehicle through August 2031; a $3.8 million delivery order from the Navy's Engineering Support Center Huntsville (September 2022) for resource efficiency management services supporting Naval Facilities Engineering Command Far East through March 2028; and recurring $58,000–$922,000 delivery orders from the Army Joint Munitions Command for low-level radioactive waste transportation, disposal, and packaging services from 2021 through 2023.

Customer concentration skews military and defense infrastructure. The top five customer components account for 72% of awards by count but only 51% of combined potential value, reflecting the outsized weight of two NIH and Army Corps of Engineers awards. By potential value, the top five account for 90% of dollars: the National Institutes of Health Construction leads with three awards carrying $406.4 million combined potential value (almost two-thirds of the entire portfolio), followed by the Department of the Army ($50.3 million across 16 awards), the Army Corps of Engineers Engineering Support Center Huntsville ($48.8 million across two awards), the Joint Munitions Command ($26.5 million across 50 awards), and the Army Corps of Engineers Engineering District Baltimore ($19.6 million across 18 awards). The vendor's largest awards are architectural-engineering and capital construction projects; its most frequent customer (Joint Munitions Command) issues smaller, recurring task orders for waste management and disposal support.

Salas O'Brien Federal holds a $400 million multiple-award Indefinite Delivery Contract with NIH Construction (FY26 A/E MATOC Design Services, awarded June 2026, performance through June 2032) and a multi-billion-dollar ceiling position on the OASIS+ Unrestricted IDIQ (awarded December 2024, performance through December 2029). The firm also operates under five large Army IDCs as a prime: W91ZLK19D0004 (22 task orders, $3.6 million combined potential value), W91ZLK16D0004 (20 task orders, $3.5 million), W52P1J19D0027 (15 task orders, $3 million), W912DR21D0011 (14 task orders, $5.1 million), and W52P1J21D0038 (7 task orders, $1.9 million). The firm also holds a Navy Multiple Award Schedule position supporting the $3.8 million NAVFAC Far East delivery order.

Activity declined from 2022 (18 awards) to 2026 (five awards year to date), reflecting the lumpiness typical of capital-construction and large-project procurement rather than a sustained trajectory shift. Four awards with combined potential value of $49.8 million face ultimate completion inside the next twenty-four months, representing moderate recompete exposure. In its subcontractor role, Salas O'Brien Federal delivers research support services to Leidos and management and operating services to Consolidated Nuclear Security across Department of Energy and Department of Defense programs; sub work accounts for 1% of the recent award portfolio by count.

Across SCI-reportable prime contracts, the vendor invoiced $2.7 million in FY2024 at median government-paid rates around $117.68 per hour, with 14.6 FTEs delivered to federal agencies that fiscal year and an average subcontractor share of 42% of hours across those contracts. The firm maintains a GSA Schedule with 20 active labor categories ranging from $70.06 per hour (administrative support) to $284.57 per hour (senior project manager), with no security-cleared labor offered. The labor portfolio reflects engineering, project management, technical support, and administrative resource capability across non-cleared positions from high school through bachelor's-degree level.
