Hensel Phelps Construction Co

Hensel Phelps Construction Co, a for-profit general contractor headquartered in Greeley, Colorado, is a pure prime contractor delivering design-build and design-bid-build military construction and infrastructure projects to the Department of Navy, Marine Corps, Air Force, and Army Corps of Engineers, operating exclusively in full-and-open competitions with no SBA set-aside designations across its federal footprint. The company holds a substantial position on multiple Naval Facilities Engineering Command indefinite delivery contracts covering Hawaii, Wake Island, and Guam, where it executes task orders ranging from $25 million to over $90 million in value.

Hensel Phelps' customer concentration is heavily skewed toward the Navy. The Naval Facilities Engineering Command accounts for 23 of 35 named awards (covering 88% of awards by count) with $44.88 billion combined potential value—a scale driven principally by three large IDIQ positions: the $24 billion Unrestricted Design-Bid-Build Hawaii & Wake Island MACC (awarded June 2025, completion June 2033), the $15 billion Design-Build Multiple Award Construction Contract for Guam (awarded September 2025, completion September 2033), and the $2.5 billion Facilities and Infrastructure contract for Guam and other Pacific areas (awarded March 2023, completion March 2028). The Army Corps of Engineers Engineering District Honolulu ranks second with 7 awards worth $1.31 billion; the Marine Corps, Navy Installations Command, and the U.S. Geological Survey round out the customer set. Recent concrete delivery orders include a $82.752 million repair and conversion of taxilanes and pavements at Joint Base Pearl Harbor Hickam (ultimate completion December 2028), a $65.244 million REPAIR 23 ROW order at Pearl Harbor (completion February 2028), a $78.079 million inner Apra Harbor resiliency upgrade at Naval Base Guam (completion August 2028), a $48.5 million waste transfer facility at Naval Base Guam Finegayan (completion July 2029), and a $98.958 million secure integration support laboratory in Maui for the Air Force (completed March 2027).

On vehicle positioning, Hensel Phelps holds primary seats on the Navy's regional construction MACCs and indefinite delivery contracts rather than government-wide vehicles. The NAVFAC MACC for Guam and Other Areas in the Pacific carries six task orders worth $357.6 million; the DB/DBB MACC Various Locations in Hawaii carries five task orders worth $423.9 million; the Unrestricted Design-Bid-Build Hawaii & Wake Island MACC carries three task orders worth $170.4 million; and the Facilities and Infrastructure contract carries three task orders worth $126.6 million. The company does not appear on GSA Schedules, Alliant, or other government-wide acquisition contracts.

Activity has remained volatile but elevated. The awards-per-year trajectory shows four awards in 2022, four in 2023, one in 2024, six in 2025, and four through mid-2026. With five awards carrying ultimate completion dates within the next twenty-four months (combined potential value $387.1 million), Hensel Phelps faces modest near-term recompete exposure concentrated on the two largest vehicles—the Hawaii and Guam IDIQs where task order completion dates align with the 2027–2029 window.

Service Contract Inventory data captures only one active prime contract: the $122.4 million USGS Big Island Hawaii facilities construction project (awarded September 2022, completion February 2027). SCI invoicing rose sharply from $515 thousand in FY2023 to $15.2 million in FY2024 to $50.1 million in FY2025, tracking the transition from design to active construction. The contract deployed 53.1 FTEs in FY2025 on federal services, with government-paid hourly rates derived at a median of $501.03/hr across the three-year invoiced span, ranging from $462.53/hr (10th percentile) to $664.92/hr (90th percentile). Across this SCI-reportable prime contract, subcontractors performed 29 percent of total contractor hours, with 19 named subs engaged; this sub-engagement pattern reflects construction project execution where the prime manages design, scheduling, and coordination while subcontractors execute specialized disciplines (mechanical, electrical, plumbing, structural concrete, blast doors, commissioning). On a $91.6 million earth-covered magazines project at Andersen Air Force Base, Hensel Phelps engaged a robust subcontractor team including Industrial Door Contractors for blast doors, Scott Morton Manufacturing for blast door boltworks, Macks Construction for drilled caissons, Guam Advance Enterprises for mechanical and drainage systems, VG Gozum Construction for exterior finishes, MEP Commissioning for commissioning services, and Landscape Management Systems for temporary facilities. Primary NAICS framing centers on 236220 (Commercial and Institutional Building Construction), with secondary exposure in heavy and civil engineering construction. Hensel Phelps competes exclusively on unrestricted, full-and-open procurements; the company does not pursue or hold set-aside categories.
