RJ Lee Group Inc.

RJ Lee Group Inc., a for-profit Subchapter S corporation headquartered in Monroeville, Pennsylvania, provides materials characterization, aerosol analysis, and specialized scientific and technical services to federal agencies primarily as a prime contractor (98% of recent awards) across full-and-open procurement, with no small business set-aside designation in its core portfolio. The firm operates across environmental consulting, advanced microscopy and spectroscopy, forensic testing, and research-and-development capabilities grounded in electron microscopy, passive aerosol sampling, materials analysis, and data analytics.

RJ Lee Group's award portfolio reflects extreme customer and dollar concentration anchored by a single massive vehicle. The Department of the Air Force accounts for 99% of combined potential value across all awards—driven almost entirely by a $975 million Indefinite Delivery Contract with the Air Force Rapid Sustainment Directorate Multi-Award Contract (RO MAC) running through July 29, 2033. The second and third tiers are the Department of the Air Force Materiel Command ($17.5 million across 8 awards) and the Air Force Materiel Command Research Laboratory ($7.9 million across 7 awards). By award count rather than dollars, the Centers for Disease Control and Prevention Pittsburgh dominates with 30 awards ($759 thousand combined potential value), the Department of the Treasury United States Mint holds 21 awards, and the Department of the Navy carries 16 awards—collectively representing 46% of recent awards but contributing only a fraction of overall potential value. The concentration divergence reflects RJ Lee Group's role: a substantial federal vendor on small discrete purchases across health, environmental, and defense agencies, but a mega-vehicle holder under a single Air Force platform. Within the RO MAC vehicle, RJ Lee Group is positioned to deliver materials characterization, forensic testing, aerosol characterization, nanotechnology-impact analysis, energetic materials analysis, and legacy data digitization across multiple Air Force commands.

RJ Lee Group's recent award activity is sparse and declining—one award in 2022, five in 2023, five in 2024, two in 2025, and four in 2026 as of September—with only three awards (combined potential value $208 thousand) facing ultimate completion inside the next twenty-four months and therefore exposed to recompete. The firm's SCI-reported federal service contract activity shows minimal penetration: one SCI record in FY2025 as a named subcontractor, representing 0.7 FTEs. This sparse SCI footprint reflects RJ Lee Group's business model—the firm operates primarily on small, discrete purchase orders for laboratory analysis and specialized technical services rather than labor-intensive government contracts captured above the $150,000 SCI reporting threshold. Obligated dollars across all 187 awards total $58.5 million (6% of the $1.02 billion combined potential value), indicating significant optionality remaining across RO MAC and other vehicles.

RJ Lee Group works as a subcontractor to Hanford Tank Waste Operations & Closure LLC on industrial hygiene program work and materials provision under the Integrated Tank Disposition Contract, and to Tetra Tech Inc. on geotechnical laboratory services for EPA under the RAES II contract. Representative prime work spans a $4.255 million Air Force Research Laboratory SBIR Phase II contract (February 2023) for enhancement of connectivity and computational assets for the 711th Human Performance Wing; a $975 thousand Air Force Materiel Command SBIR Phase II contract (June 2024) for artificial intelligence capabilities enabling engineering speed and agility; a $1.125 million Air Combat Command SBIR Phase II contract (September 2022) for machine learning applied to B-52 modernization; recent CDC purchase orders including $130 thousand for environmental analytical and characterization services (September 2026), $99.5 thousand for aerosol characterization (August 2023), and $51.5 thousand for mineral content quantification (July 2024); a $64.7 thousand NASA Shared Services Center purchase order for ISS Aerosol Passive Sampler Analysis (July 2025); and a $55 thousand EPA Office of Research and Development order for design and development of an Event-Triggered Passive Aerosol Sampling device (December 2024). Across 187 awards spanning 1991 to the present, RJ Lee Group has served 39 distinct federal agencies.

RJLG provides consulting, contract research, analysis, and expert testimony in materials characterization fields. Analyses address industrial hygiene, environmental, criminal forensic, materials failure, construction defect, and other materials problems.
