Ch2M Hill, Inc.

Ch2M Hill, Inc., a subsidiary of Jacobs Engineering Group Inc., is a large engineering and construction firm that delivers environmental consulting, remediation, facilities support, and architect-engineering services to the federal government as a prime contractor across 163 distinct customer agencies, with cumulative federal award potential of $19.69 billion and a recent footprint dominated by Department of the Navy and Environmental Protection Agency work.

Ch2M Hill operates as a full-and-open prime contractor with no set-aside designations across its federal portfolio. The vendor is headquartered in Denver, Colorado (at 7001 E Belleview Ave), and competes across multiple NAICS categories centered on engineering services (1,870 awards), environmental consulting services (358 awards), and architectural services (246 awards). Over the past five years, Ch2M Hill's award velocity has declined from 165 awards in 2022 to 24 awards in 2026, though the vendor maintains substantial ongoing task order activity under established IDIQ vehicles. The vendor's combined obligations through SCI reporting show $135.7 million invoiced across federal service contracts from FY2022 through FY2025, spanning 73 to 130 federal FTEs annually, with government-paid hourly rates ranging from approximately $61/hr at the tenth percentile to $334/hr at the 90th percentile (median $127/hr).

Customer concentration sits heavily with the Navy. The Department of the Navy Naval Facilities Engineering Command (NAVFAC) accounts for 689 awards carrying $2.33 billion in combined potential value—the single largest federal customer by both volume and dollars. The Department of the Air Force ranks second by award count (376 awards) but carries minimal dollar value ($236 thousand combined), suggesting small task orders. By potential value, the Air Force Materiel Command Installation and Mission Support Center Civil Engineer Center dominates with 33 awards totaling $5.08 billion, reflecting large standing IDIQs rather than award volume. The Environmental Protection Agency Region 5 (33 awards, $572.4 million) and the Army Corps of Engineers (28 awards, $834.3 million) are also significant federal customers. The top five customer agencies by both metrics account for 53% of awards by count and 46% by potential value.

Ch2M Hill holds two major parent vehicles anchoring its federal footprint: an $80 million single-award indefinite-delivery contract with Naval Facilities Engineering Command for architect-engineering multimedia services (extended through December 2029, exercised Option Year 1 as of December 2024) and a $480 million single-award Comprehensive Long-Term Environmental Action Navy (CLEAN) indefinite-delivery contract awarded May 28, 2026, also with NAVFAC, running through May 27, 2031 on a cost-plus-award-fee basis. The CLEAN contract represents a recent major vehicle expansion reflecting the vendor's established role in Navy environmental restoration. Under these vehicles, Ch2M Hill issues numerous task orders for environmental site assessments, remedial investigations, PFAS (per- and polyfluoroalkyl substances) investigations, unexploded ordnance surveys, stormwater and spill prevention management, hazardous waste planning, and facilities engineering across Navy and Marine Corps installations domestically and overseas (Spain, Poland, Djibouti, Israel). Substantial task order activity also flows through the Navy's architect-engineering IDIQ N6247021D0007 (278 task orders, $463.7 million combined potential) and N6247016D9000 (251 task orders, $361.6 million), as well as a Federal Supply Schedule contract GS10F0132K (247 task orders, $51 million). The EPA Remedial Acquisition Framework: Design and Engineering Services (DES) is a critical vehicle for Ch2M Hill's environmental remediation work, particularly in EPA Regions 5 and 9, supporting Superfund site design, feasibility studies, and remedial action oversight.

Ch2M Hill operates predominantly as a prime contractor, with 3,009 of 3,010 recent awards held as prime (100% prime split). Across SCI-reportable service contracts, the vendor employs subcontractors at a low rate—an average of 2% of total contractor hours subcontracted across prime records. Named subcontractors appearing in the award detail include environmental testing and laboratory firms (Eurofins Environment Testing Northern California LLC, ECO Analysts LLC, Eurofins Lancaster Laboratories), drilling and remediation specialists (Gregg Drilling LLC, an 8(a)-certified Alaska Native-owned firm; Yellow Jacket Drilling Services LLC), women-owned small businesses (Engineering / Remediation Resources Group Inc., Exact Stormwater Management LLC, Athena Engineering & Environmental LLC, M.p. Environmental Services Inc.), veteran-owned firms (American Environmental & Construction Services Inc., Ground Zero Field Services LLC), and specialized consulting and surveying firms (Naeva Inc., Bowman Consulting Group LTD). The vendor frequently engages 31 named subcontractors over the SCI reporting period, suggesting a controlled supply chain focused on fill-in technical and specialized capabilities rather than broad teaming arrangements.

Recent representative work grounded in the federal contract awards includes: a $24.6 million delivery order from EPA Region 9 (awarded September 30, 2024) for remedial design and remedial action support at the Sulphur Bank Mercury Mine, with work through September 26, 2029, under the EPA RAF DES vehicle, invoicing $2 million in FY2025 across 7.7 FTEs and engaging subcontractors including the Alaska Native-owned Gregg Drilling LLC and woman-owned Engineering / Remediation Resources Group Inc.; an $11 million delivery order from EPA Region 4 (awarded March 27, 2026) for remedial design and remedial action oversight at the Southside Chattanooga Lead Site, with cost-plus-fixed-fee pricing and completion through March 26, 2030; a $19.1 million delivery order from EPA Region 9 (awarded September 29, 2025) for remedial design and remedial action support at the Iron King Mine-Humboldt Smelter project, with a team of environmental testing and remediation subcontractors and FY2025 invoicing approaching $2 million; and extensive work under NAVFAC including a $4.776 million delivery order (awarded September 21, 2026) for multi-site remedial design and engineering services under the EPA Remedial Acquisition Framework with ultimate completion September 20, 2031. Ch2M Hill also executes NASA Marshall Space Flight Center task orders for site remediation, vapor intrusion monitoring, environmental compliance support, and regulatory risk analysis, with recent orders in the $100K–$900K range demonstrating sustained smaller-dollar NASA engagement.

Recompete exposure in the next 24 months totals 255 awards carrying combined potential value of $564.3 million, primarily represented by the expiring NAVFAC architect-engineering IDIQ and numerous smaller delivery orders set to complete between September 2024 and September 2026. The vendor's FTE trajectory shows growth from 73 FTEs in FY2022 to a peak of 130 FTEs in FY2024, declining slightly to 102 FTEs in FY2025, consistent with the declining award volume trend. Corporate structure places Ch2M Hill as a wholly owned subsidiary of Ch2M Hill Companies, LTD., the parent holding company.
