About the company
The Cadmus Group LLC, an employee-owned limited liability company headquartered in Arlington, Virginia, delivers environmental protection, water infrastructure, emergency management, and program management services to federal agencies as a prime contractor on an unrestricted, full-and-open competitive basis with no small-business set-asides. The firm operates three subsidiaries—Wheelhouse Group LLC, Obsidian Analysis LLC, and Ventera LLC—and competes across 1,240 recent federal awards spanning environmental consulting, administrative management consulting, marketing consulting, and engineering services.
Cadmus anchors its federal footprint in water and environmental technical assistance. The Environmental Protection Agency's Office of Water dominates the customer set, accounting for 202 awards worth $1.06 billion in combined potential value, anchored by a $162 million single-award IDIQ (established January 15, 2023, through January 14, 2028) supporting Safe Drinking Water Act implementation. Representative work includes a $26.96 million delivery order for water technical engineering support services for the Office of Ground Water and Drinking Water (awarded June 24, 2024), a $20.8 million order for drinking water infrastructure support (awarded September 17, 2026), and a $12.3 million order for technical and administrative support to the Underground Injection Control Class VI Program (awarded September 30, 2025). Beyond EPA Office of Water, Cadmus serves the EPA Office of Air and Radiation (174 awards, $249.7 million), Federal Emergency Management Agency (78 awards, $225.9 million), and the Department of Transportation Federal Highway Administration (44 awards, $80.5 million). FEMA work centers on disaster recovery planning, resilience coordination, and emergency management support under a $75 million single-award BPA with the Office of Response and Recovery (established January 28, 2025, through May 19, 2027). Federal Highway Administration work includes a $26.99 million delivery order for the Reconnecting Communities Institute program (awarded July 25, 2023, under OASIS IDIQ).
Cadmus holds parent positions on multiple government-wide vehicles. The firm was awarded a seat on NASA's SEWP VI GWAC (November 1, 2026) with a $20 billion ceiling through October 31, 2036. It maintains positions on Alliant 3 GWAC (awarded February 25, 2026, with a multi-trillion-dollar ceiling through March 9, 2036) and OASIS+ Unrestricted IDIQ (awarded December 17, 2024, with a multi-trillion-dollar ceiling through December 16, 2029). Cadmus also holds the Missile Defense Agency's SHIELD multiple-award IDIQ (awarded December 29, 2025, with a $151 billion ceiling through December 28, 2035), positioning the firm to compete for defense-sector work. Agency-specific vehicles include a $20 million BPA with the Federal Railroad Administration for RRD-30 realty services (awarded July 15, 2026), a $20 million BPA with the Millennium Challenge Corporation for threshold program support (awarded June 8, 2026), and a $12 million BPA with the Office of the Assistant Secretary for Preparedness and Response for exercise, evaluation, and after-action support (awarded September 30, 2026). The firm maintains active GSA Schedule labor rates spanning 16 categories from $61.79 per hour (administrative support) through $383.27 per hour (senior executive consultant), requiring bachelor's degrees with no security clearances.
Activity has grown sharply. Awards per year increased from 45 in 2022 to 79 in 2024 before moderating to 33 in 2026 (first 11 months). SCI-reported invoiced revenue on federal service contracts above the $150,000 threshold grew from $16 million in FY2022 across 64.1 FTEs to $71.2 million in FY2025 across 170 FTEs, reflecting 345% growth in invoicing and 165% growth in federal service delivery staff over three years. The firm derived median government-paid hourly rates of $136.04 per hour across SCI-reportable prime contracts, with the 90th percentile at $227.28 per hour. Across SCI-reportable prime contracts, Cadmus self-performs approximately 91% of contractor hours and engages 182 named subcontractors for roughly 9% of hours, indicating a predominantly prime-delivery posture with targeted subcontractor support. Sixty-six awards worth $240.2 million in combined potential value reach ultimate completion within the next twenty-four months, creating recompete exposure.
As a subcontractor, Cadmus delivers specialized services to Booz Allen Hamilton (cybersecurity and management consulting), Leidos (energy and water benchmarking), ICF Incorporated (EPA Energy Star program support), Deloitte Consulting (health security and officer health bridge services), Riverside Technology (NOAA strategy and performance support), The Aerospace Corporation (NASA NEON Earth Observation network outreach and engagement), and Consolidated Safety Services (NOAA NCEI scientific data stewardship). Grant work as sub-recipient includes technical assistance to International City/County Management Association across multiple EPA-funded local government resilience and sustainability programs.
