Ch2M Hill Constructors Inc.

Ch2M Hill Constructors Inc., a subsidiary of the Denver-based engineering and construction firm Ch2M Hill Companies, Ltd., operates as a prime contractor on federal construction, engineering, and environmental remediation projects—predominantly for the Department of the Air Force and the U.S. Army Corps of Engineers. The vendor holds a 95% prime-contract footprint across its recent awards, with work spanning architecture and engineering design, site remediation, and building construction services across domestic and international locations.

Ch2M Hill Constructors' customer concentration is heavily skewed by a single award. The Department of the Air Force Air Combat Command anchors $10 billion in combined potential value on a single contract—99% of the vendor's total potential-value portfolio—while the remainder of the award base fragments across thirteen federal agencies. By count, the Air Force commands 25 awards (29% of all awards in the source dataset), with the Federal Highway Administration, the Army Corps of Engineers, and the Air Force Air Education and Training Command representing secondary customer relationships. The Department of the Army Corps of Engineers Engineering Support Center Huntsville and Engineering District Baltimore collectively hold $791.4 million in combined potential value across six awards. The largest single dollar awards outside the $10 billion Air Force contract are a $600 million engineering support assignment from the Corps of Engineers Support Center Huntsville and a $154.6 million National Science Foundation Division of Polar Programs award.

Ch2M Hill Constructors places task orders under multiple indefinite-delivery vehicles, with 27 task orders under Federal Highway Administration IDC DTFH6802D00008 carrying $3.5 million in combined potential value, 24 task orders under Air Force IDC F4162403D8595, 9 task orders under the Air Force Construction Services IDIQ 2008-2018 (worth $20.6 million), and 7 task orders under Army Corps of Engineers IDC W912DR09D0004 (worth $47.1 million). The vendor's service category concentration runs across engineering services (27 awards), architectural services (24 awards), commercial and institutional building construction (12 awards), and environmental remediation (12 awards), with PSC framing dominated by Architect and Engineering General classifications.

Recent activity is sparse in the source data: two awards in 2022 and two in 2023, with the most recent award dating to November 2023. Combined obligated dollars across all awards total $308 million (3% of the $11.05 billion combined potential value), indicating substantial unobligated pipeline but inactive award progression over the past two-and-a-half years. The vendor's only SCI-reported activity in the dataset shows 0.1 FTEs as a named subcontractor in FY2022, reflecting minimal service-contract reporting and indicating that Ch2M Hill Constructors' federal footprint is dominated by construction and engineering deliverables rather than labor-hour service contracts. In its minimal subcontractor role, the vendor delivers performance-based remediation services to EA Engineering, Science, and Technology, Inc., PBC at Joint Base Cape Cod, Massachusetts across multiple sub-awards dating 2022 through 2023.
