The Cadmus Group LLC

The Cadmus Group LLC, an employee-owned consulting firm headquartered in Arlington, Virginia, delivers environmental protection, water infrastructure, emergency management, and program management services to federal agencies primarily as a prime contractor (97% of awards), competing on an unrestricted, full-and-open basis with no small-business set-asides. The firm operates three subsidiaries—Wheelhouse Group LLC, Obsidian Analysis LLC, and Ventera LLC—and maintains active labor rates on the GSA Schedule ranging from $59.99 to $372.11 per hour across 16 categories pitched to bachelor's-level professional and senior consulting roles without security clearance requirements.

The Cadmus Group's federal footprint centers on environmental and water technical assistance. The Environmental Protection Agency's Office of Water dominates the portfolio, anchoring $1.03 billion in combined potential value across 199 awards, primarily task orders flowing from a $162 million single-award IDIQ established January 15, 2023, through January 14, 2028, that has already generated over $70 million in cumulative awards addressing Safe Drinking Water Act implementation. Representative work includes a $26.96 million delivery order for water technical engineering support (June 2024), a $12.27 million task order for Underground Injection Control Class VI program support (September 2025), a $4.48 million Region 5 delivery order for drinking water technical assistance to tribal public water systems (July 2026), and dozens of smaller task orders spanning lead service line replacement, PFAS regulatory development, Drinking Water Infrastructure Needs Survey support, and state revolving fund program administration. EPA Office of Air and Radiation ranks second at $249.7 million across 174 awards, reflecting work in compliance advisory services and environmental regulatory support.

The Federal Emergency Management Agency comprises the third-largest customer relationship. The Cadmus Group holds a $75 million single-award Blanket Purchase Agreement with FEMA's Office of Response and Recovery (established January 28, 2025, through May 19, 2027) under the GSA Multiple Award Schedule. Recent task orders under this vehicle total approximately $13.0 million in aggregate ceiling value, including $6.97 million for Build America Buy America Act waiver management support (completion September 2030), $3.75 million for U.S. Virgin Islands government support (completion September 2026), and $1.43 million for State Technical Assistance for Recovery Strategies Program support (completion September 2026). Cadmus also subcontracts for FEMA, delivering incident management assistance team training and other emergency management services to other primes.

Beyond EPA and FEMA, Cadmus competes broadly across civilian federal agencies. The Federal Highway Administration awarded a $15 million multiple-award BPA (September 2022–September 2027) from which five task orders totaling approximately $1.55 million have been issued for transportation planning, air and noise pollution mitigation, and community displacement prevention studies. The Millennium Challenge Corporation established a $20 million single-award BPA with Cadmus on June 8, 2026, for threshold program support services. The General Services Administration awarded positions on two government-wide acquisition vehicles: OASIS+ Unrestricted IDIQ (December 17, 2024, through December 16, 2029, with no dollar ceiling specified in the source) for professional services across all federal agencies, and Alliant 3 GWAC (February 25, 2026, through March 9, 2036, with no dollar ceiling specified in the source) for IT services-based solutions. The Missile Defense Agency included Cadmus on a $151 billion multiple-award Scalable Homeland Innovative Enterprise Layered Defense contract (December 2025–December 2035), though only a nominal $500 delivery order has been awarded to date.

Recent award activity shows deceleration: 45 awards in 2022, 70 in 2023, 79 in 2024, 53 in 2025, and 17 in 2026 (partial year). Sixty-two awards with ultimate completion in the next twenty-four months carry combined potential value of $54.7 million, representing near-term recompete opportunity and risk exposure. The Environmental Protection Agency's $162 million Office of Water IDIQ expires January 14, 2028—a major vehicle requiring renewal or replacement.

Cadmus's Service Contract Inventory profile shows SCI-reportable invoicing of $89.5 million across FY2022–FY2024 (220 prime records, 37 subcontractor records), with growth trajectory: $16 million in FY2022, $24.5 million in FY2023, and $49.1 million in FY2024. The company deployed 67.7 FTEs in FY2022, 91.7 in FY2023, and 105 in FY2024 across SCI-reportable federal services contracts. Government-paid hourly rates on those contracts ran median $134.08 per hour, with the 10th percentile at $104.61 per hour and the 90th percentile at $228.78 per hour. Across SCI-reportable prime contracts, subcontractors performed 10% of total contractor hours on average; Cadmus engages approximately 133 named subcontractors across its prime work, indicating a delivery model that builds internal capacity while deploying specialized subs for technical depth.

Cadmus subcontracts to larger primes in specialized domains. Named sub relationships include The Aerospace Corporation on NASA-wide specialized engineering and satellite value studies (April and November 2025), Booz Allen Hamilton on cybersecurity management consulting (October 2025 and October 2023), Riverside Technology on NOAA strategy and performance management support (September 2024), Deloitte Consulting on DHS health security bridge services (December 2023 and June 2024), ICF Incorporated on EPA ENERGY STAR program outreach (December 2023 and April 2024), and Leidos on energy and water benchmarking services (February 2024). Grant sub-awards position Cadmus under International City/County Management Association for technical assistance and training delivery across multiple EPA-funded local government resilience and sustainability programs (January 2023–June 2025).

Concentration by business function reflects environmental and management consulting dominance: Environmental Consulting Services accounts for 367 awards, Administrative and General Management Consulting Services for 175, Marketing Consulting Services for 130, and Engineering Services for 34. Primary Service Classification codes mirror this pattern: Support–Professional (Other) spans 358 awards, Program Management/Support covers 140, and Engineering/Technical accounts for 140. Combined, the top five NAICS and PSC categories represent approximately 70% of recent award volume, signaling a focused practice area aligned with EPA and federal emergency management priorities rather than diversified technology or defense contractor positioning.

The Cadmus Group competes without set-aside designation and places all major vehicles on full-and-open, unrestricted contract vehicles—OASIS+, Alliant 3, EPA MAS, GSA MAS, FEMA MAS—reflecting established competitive standing in the civilian federal marketplace. The firm's $3.19 billion combined potential value across 1,225 total awards (1990–2026) and $934.4 million in obligations (29% realization rate) demonstrates sustained engagement across environmental, water, emergency management, and strategic consulting domains, with highest concentration in EPA water programs and FEMA emergency response operations.
