Hensel Phelps Construction Co

Hensel Phelps Construction Co, based in Greeley, Colorado, is a major design-build and design-bid-build general contractor that operates exclusively as a prime contractor on $16.04 billion in combined federal construction work across 114 awards spanning 28 customer agencies. The firm is a for-profit partnership or limited liability partnership with no set-aside designations; it competes full-and-open across federal construction work. The company's federal footprint centers on institutional, industrial, and specialized facility construction — 99 of 114 awards fall under Commercial and Institutional Building Construction (NAICS 236220), with named work in office building construction, miscellaneous building construction, and non-building facilities.

Customer concentration is moderate and shaped by large multi-year programs. The Department of Health and Human Services National Institutes of Health Construction anchors the dollar base with 10 awards carrying $3.9 billion in combined potential value, spanning major research facility modernizations and expansions at NIH campuses in Bethesda and Poolesville, Maryland. The Department of the Army Corps of Engineers Engineering District Baltimore follows with 14 awards valued at $2.66 billion, including the $316.1 million Fort Meade Records Center Replacement and Mercury Flora Facilities design-build contract (awarded June 2022, completion February 2026) and associated project work. The Department of Justice Federal Bureau of Investigation Headquarters Division contributes 9 awards at $2.06 billion, and the Department of the Navy Naval Facilities Engineering Command holds 9 awards at $1.82 billion. These five customers account for 70% of combined potential value, with NIH, Army Corps, FBI, and Navy each anchoring major multi-year programs rather than fragmented small orders.

Hensel Phelps holds positions on five primary parent vehicles. The NIH General Construction MACC 2019 ($2 billion multiple-award IDIQ) carries 9 task orders valued at $1.4 billion, including the $765.9 million Surgery, Radiology, and Laboratory Medicine (SRLM) Building Construction project at Bethesda (awarded March 2022, ultimate completion January 2029, with FY2025 invoicing of $259.7 million across 377 FTEs), the $194.9 million VRC Laboratory Expansion at Building 40A (awarded November 2021, ultimate completion October 2026, with FY2025 labor at $291.69/hr across 97.1 FTEs), and the $138.5 million Rocky Mountain Laboratories Building J construction change order in Hamilton, Montana (awarded July 2024, with FY2025 invoicing of $28.7 million at $620.86/hr across 22.2 FTEs and 12 subcontractors performing 100% of hours). The Naval Facilities Engineering Command's Large General Construction - D.C., Maryland, and Virginia - 2023-2028 single-award indefinite delivery contract ($1.229 billion ceiling, awarded September 2023, running through September 2028) carries 3 delivery orders including the $50.8 million Joint Base Andrews hazardous cargo pad and EOD range relocation (awarded September 2023, completion December 2025) and the $5.73 million Walter Reed National Military Medical Center main operating room and scrub sink modernization (awarded September 2025, completion January 2029). An Army Corps of Engineers IDC (DOCSB134116CQ0026) carries 12 task orders at $294.9 million combined potential value. Recent smaller awards include $280,000 for NIST response preparation for a Central Utility Plant renovation and modernization RFP (awarded September 2026, estimated construction value $326.78 million over 10.5 years) and $165,000 unsuccessful-offeror stipend from NIH (awarded September 2026).

Activity has remained steady but lower in recent years—three awards in 2022, two in 2023, four in 2024, one in 2025, and two in 2026—reflecting the concentrated nature of large federal construction programs. Five awards with combined potential value of $334.7 million face ultimate completion within the next twenty-four months, creating recompete exposure in that window. Hensel Phelps operates 100% as a prime contractor; it does not appear in the sub-award portfolio and reports zero subcontractor involvement on its prime contracts in the source. However, SCI-reported service contract activity reveals that across prime contracts, subcontractors perform an average of 54% of total contractor hours, with 361 named subcontractors engaged. SCI invoicing totaled $941 million across FY2022–FY2025, with FY2025 reaching $363.6 million across 496 FTEs. Government-paid hourly rates on Hensel Phelps' federal construction service contracts span from a 10th percentile of $44.44/hr to a 90th percentile of $1,790.38/hr, with a median of $311.61/hr, reflecting the mix of labor grades across design, supervision, and field construction roles on major facility projects.
