HDR Environmental, Operations And Construction, Inc.

HDR Environmental, Operations And Construction, Inc. (HDR EOC), the Environmental, Operations and Construction division of Omaha-based HDR, Inc., operates as a prime contractor delivering architect-engineering, environmental assessment, facilities engineering, and construction management services to the federal government across 137 customer agencies, with no set-aside designations and full-and-open competitive positioning.

HDR EOC dominates the federal environmental and facilities engineering space through a $13.35 billion combined potential-value portfolio anchored by massive Air Force and Army Corps of Engineers vehicles. The vendor holds three foundational indefinite delivery contracts: a $2 billion Architect-Engineering Services for Design and Construction Support (AE NEXT) IDIQ with the Air Force Civil Engineer Center covering airfield infrastructure, design-build, and facilities support; a $249 million Environmental Quality Program (EQP) MATOC with the Army Corps of Engineers South Atlantic Division for environmental compliance, planning, conservation, NEPA, and infrastructure restoration; and a $249 million separate A-E services vehicle with the USACE Mobile District for planning and environmental support across civil works and military programs in the southwest and south-central regions. An additional $100 million Environmental Assessment contract with the Air Force Civil Engineer Center, awarded September 2025, provides environmental impact statements and regulatory compliance work through 2030. Most recently, HDR EOC received a $75 million single-award vehicle from Naval Facilities Engineering Command for marine and biological resources monitoring and program management across the Atlantic and Pacific areas of responsibility, awarded September 2025 through 2030. The vendor also holds a $50 million GSA Multiple Award Schedule for environmental consulting, GIS, and environmental remediation services and sits on the OASIS+ Unrestricted multiple-award platform. Across these vehicles, the Air Force Civil Engineer Center alone accounts for roughly 98 awards valued at $9.11 billion in combined potential value—nearly 68 percent of the total portfolio—while the Army Corps of Engineers Mobile District contributes 93 awards worth $1.82 billion.

Recent representative prime work reflects the vendor's core capability set: a $14.8 million delivery order from the Department of Defense Southeast Region for JBLM A&E support services (April 2026, firm fixed price, through April 2031); a $8.69 million Air Force Civil Engineer Center task order for Title II and AE services supporting MILCON and facility sustainment projects in San Antonio (October 2025); a $12.2 million Defense Logistics Agency master planning and engineering design order under AE NEXT (September 2024); a $5 million delivery order from the Defense Logistics Agency for architect-engineer services supporting facilities engineering worldwide under AE NEXT (September 2025); a $6.9 million U.S. Marine Corps Forces Reserve real property management and environmental planning task order in New Orleans (September 2024); a $4.6 million ENDIST Mobile order for real property management and environmental planning support for Marine Forces Reserve (September 2025); a $22.6 million Office of the Secretary of Defense award for Force Design Optimization Plans and Installation Master Plans across seven Marine Corps installations (September 2022); and numerous marine species monitoring task orders under Navy contracts, including a $597,882 SURTASS compliance and monitoring order (February 2022) and coastal sediment sampling and permitting work valued at $765,827 (April 2026) for Naval Facilities Engineering Command. Environmental restoration and hazardous waste remediation form a secondary revenue stream: a $2.67 million task order for environmental restoration support and sampling at Defense Depot Memphis Tennessee running through December 2029, and a $1.24 million remedial design order for the Longhorn Army Ammunition Plant in Texas. In its subcontractor capacity, HDR EOC performs specialized work under larger primes including environmental assessment and field oversight for Aerojet Superfund site remedial investigation work on University of California San Diego contracts and environmental support services for multiple Dawson-led vehicles.

Across SCI-reportable federal service contracts above the $150,000 threshold (a partial view excluding goods, classified work, and smaller procurements), HDR EOC invoiced approximately $5.4 million across fiscal years 2022–2024: $2.6 million in FY2022 on 4.2 FTEs, $1.7 million in FY2023 on 2.6 FTEs, and $1.2 million in FY2024 on 1.6 FTEs. Government-paid hourly rates on SCI-reportable contracts ranged from $152/hr at the tenth percentile to a median of $354/hr, with senior labor pricing through $669/hr. On GSA Schedule 47QRAA22D00AR (awarded June 2022, ceiling $50 million through June 2027), HDR EOC maintains 42 active labor categories spanning environmental auditors, hazardous waste specialists, GIS operators, environmental scientists, construction supervisors, and senior project managers at rates from $56.69/hr (junior environmental auditor) to $201.62/hr (senior project manager), all requiring a bachelor's degree and no security clearances.

HDR EOC leans on subcontractors across prime contracts, with SCI data showing an average sub-hours share of 28 percent of total contractor hours on reportable service work, engaging eight distinct named subcontractors including Colorado Network Staffing Inc. (woman-owned small business, labor support), CSA Ocean Sciences Inc. (marine science and monitoring), Marine Acoustics Inc. (marine acoustics engineering), EA Engineering Science and Technology Inc. (environmental consulting), Involve LLC (veteran-owned small business, property management and facilities assessment), and academic partners including the University of St Andrews, Duke University, and Woods Hole Oceanographic Institution for marine species research and modeling. Named prime contractors that HDR EOC subcontracts to include Barron Associates Inc., Dawson McGill Inc., Aktarius LLC, and Akima Intra-Data LLC on task orders involving environmental assessment, base operations support, and specialized technical services. The vendor's teaming model emphasizes bringing specialized subcontractors—particularly small businesses, minority-owned firms, and academic institutions—to enhance technical depth on environmental monitoring, marine science, remediation, and facility engineering scopes.

Activity has remained steady, with 51 awards in FY2022 declining to 35 in FY2025 and 9 in the first quarter of FY2026. Sixty-nine awards carrying combined potential value of $193.7 million face ultimate completion within the next twenty-four months, signaling recompete exposure in environmental assessment, facilities engineering, and marine monitoring areas. The vendor's award profile is heavily concentrated in environmental and architectural engineering disciplines—703 awards carry Engineering Services NAICS, 647 cite Remediation Services, and 597 reference Environmental Consulting Services—with PSC codes dominated by Architect and Engineering services (564 awards) and Other Environmental Services (560 awards). The parent company HDR, Inc., a 100 percent employee-owned professional services firm headquartered in Omaha, Nebraska, with roots tracing to 1917, maintains an established federal presence spanning architecture, engineering, environmental consulting, and construction across civilian, defense, and infrastructure programs, with additional named subsidiary divisions including HDR Aptim LLC and HDR O'Brien & Gere, A Joint Venture.
