About the company
Tetrahedron, Inc., a woman-owned, minority-owned small business based in Baltimore, Maryland, provides environmental consulting, engineering, and compliance services to federal civilian and defense agencies as a prime contractor, with no subcontract footprint across a 43-award federal portfolio. The company holds SBA certifications as a minority-owned (Subcontinent Asian American) and woman-owned small business, and is self-certified as a small disadvantaged business and DOT-certified DBE. All recent awards are prime contracts with no set-aside designation.
Tetrahedron's work concentrates in environmental consulting and engineering services. The top two funding sources by dollar value are the Environmental Protection Agency's Office of Chemical Safety and Pollution Prevention (2 awards, $9.5 million combined potential value) and GSA Federal Acquisition Service (2 awards, $9.3 million), which together account for 98% of the portfolio's combined potential value. The Department of the Army Corps of Engineers' Engineering District Tulsa follows with 9 awards totaling $5.1 million combined potential value, anchoring the vendor's Army presence. The portfolio spans 14 distinct customer agencies, with the top five accounting for 58% of all awards. NAICS concentration runs to Environmental Consulting Services (24 awards) and Engineering Services (9 awards); PSC codes track to Other Environmental Services (14 awards) and Architect and Engineering—General (13 awards).
Tetrahedron holds a GSA Multiple Award Schedule contract (ceiling $4 million, running through November 2028) offering 16 labor categories across technical, managerial, and administrative roles at hourly rates spanning $49.06 for clerical support to $197.84 for program management, with education requirements from bachelor's to master's degree and no security-cleared positions. Recent work includes an August 2025 $74,988 firm fixed-price purchase order from the Joint Munitions Command for Oklahoma Pollutant Discharge Elimination System permit renewal at the McAlester ammunition production facility, running through August 2030 with four option years. The vendor operates under parent vehicles including three Army Corps of Engineers IDIQs (12 task orders valued at $1.6 million under DACA3100D0032; 6 task orders at $3.9 million under W912BV07D2050) and an Agriculture IDV (2 task orders, $100 thousand). Combined potential value across all 43 awards stands at $25 million, with $12 million obligated (48% realization). Award activity is episodic across the five-year window shown — one award in 2015, five in 2016, then a gap through 2022, with one award each in 2023 and 2025 — suggesting project-based procurement cycles rather than sustained production ramp.
