HDR Environmental, Operations And Construction, Inc.

HDR Environmental, Operations And Construction, Inc., the Environmental, Operations and Construction division of Omaha-based HDR, Inc., competes as a full-and-open, non-set-aside prime contractor delivering environmental assessments, marine species monitoring, facilities engineering, and construction management services to the Department of Defense and Army Corps of Engineers. The division is a 100% employee-owned subsidiary of HDR, Inc., a global professional services firm headquartered in Nebraska, with roughly 2,594 total awards across federal and non-federal sources in the source data, yielding a combined potential value of $15.36 billion, though SCI-reportable invoiced revenue totals $15.7 million across fiscal years 2022–2025.

HDR EOC holds a foundational position on multiple large-value indefinite delivery vehicles anchoring its federal posture. The Air Force Civil Engineer Center's $2 billion Architect-Engineering Services for Design and Construction Support (AE NEXT) IDIQ is the single largest vehicle, generating hundreds of task orders for Title I and Title II design, runway repair, taxiway rehabilitation, housing requirements and market analyses, and facilities sustainment across Air Force installations worldwide. The U.S. Army Corps of Engineers South Atlantic Division's $249 million Environmental Quality Program MATOC (Architect and Engineering Services to Support the Environmental Quality Program) and the Naval Facilities Engineering Command's $75 million single-award marine and biological resources monitoring contract (awarded September 2025, through 2030) round out the core portfolio. Recent awards include a $100 million Environmental Assessment and Impact Statement Services IDIQ from AFCEC (September 2025, through 2030) and participation in GSA's OASIS+ Unrestricted program. HDR EOC also holds positions on a $50 million GSA Federal Supply Schedule for environmental consulting and GIS services and participates in single-award construction management and environmental restoration vehicles with the Army Corps of Engineers Mobile and Fort Worth Districts.

Recent capability work exemplifies the division's scope. A $22.57 million Naval Facilities Engineering Command delivery order (July 2024) covers aquatic invasive species removal at Joint Base Pearl Harbor Hickam, Hawaii, with subcontractors CSA Ocean Sciences Inc., Geotech Solutions, Inc., and 3-P Consulting Inc. handling specialized removal equipment and management. A $14.8 million AE NEXT delivery order (April 2026) for Joint Base Lewis-McChord architect-engineer support was issued to Southeast Region; the division serves as prime across Air Force, Army, Navy, DLA, and USMC customer sets. A $12.2 million DLA master planning and engineering design task order (September 2024, completion September 2028) for multiple DLA locations nationwide engaged McKim & Creed Inc. for boundary survey services. Marine species monitoring anchors a significant capability line: the division delivered FY26 Hawaii Marine Species Monitoring ($385,899, January 2026, U.S. Pacific Fleet Forces), passive acoustic monitoring for the Atlantic Fleet Training and Testing program ($1 million, June 2023, completion September 2026, with Woods Hole Oceanographic Institution and Kimora Solutions LLC as subcontractors), and nearshore and mid-shelf baleen whale monitoring ($2.47 million, December 2022, extended through December 2026, U.S. Fleet Forces Command Atlantic Fleet). Environmental compliance and restoration work includes SURTASS LFA/CLFA sonar environmental compliance support ($883,017, April 2026, completion February 2027, Naval Facilities Engineering Command), sediment sampling and joint permit applications for dredged material disposal ($2.05 million, May 2024, Naval Facilities Engineering Command), and remedial design for Site LHAAP-47 at Longhorn Army Ammunition Plant ($1.24 million, September 2022, completion June 2026, with Walker-Hill Environmental, MTX Surveying, and Environmental Monitoring Technologies LLC supporting). The division also executes architect-engineer design-build support, as evidenced by a $2.93 million task order (April 2025, completion January 2027) for Runway 15C/33C and overruns repair design at Sheppard Air Force Base, Texas, with Geotex Engineering LLC and unnamed surveying support.

Customer concentration centers on the Air Force Civil Engineer Center and Army Corps of Engineers. The Air Force IMSC Civil Engineer Center commands roughly $11.11 billion in combined potential value across 98 awards, while the Army Corps Engineering District Mobile anchors $1.82 billion across 94 awards. The Army overall (including IMSC and various corps districts) generates 461 awards at $56.4 million combined potential; the Air Force broadly (materiel command, installation support, and aviation) accounts for 260 awards across $66.4 million. The Navy's Naval Facilities Engineering Command contributes 74 awards valued at $441 million. These five customers alone represent 91% of combined potential value across the portfolio. Recent activity shows year-over-year award decline—51 awards in 2022 declining to 13 awards in the first nine months of 2026—suggesting either maturing contract consolidation under larger vehicles or recompete pressure. Within 24 months, 56 awards carrying $139.6 million combined potential value reach ultimate completion, creating moderate recompete exposure.

On the AE NEXT vehicle alone, HDR EOC holds hundreds of active task orders across airfield infrastructure, corrosion control, design review, and construction support. Delivery orders issued in the past 18 months include $8.69 million for AFCEC design reviews and Title II services (October 2025, completion September 2027); $5 million for DLA worldwide facilities engineering (September 2025, completion September 2027); $4.99 million for DLA energy resources management (September 2022, completion September 2026); and $13.5 million for DLA Distribution worldwide architect-engineering services (September 2022, completion September 2026). The Army Corps South Atlantic Division vehicle drove activity including $6.9 million for Marine Corps Forces Reserve real property management and environmental planning (September 2024, extended through September 2026, with Involve LLC and Insight Global LLC subcontracting); $5.79 million for BUILDER Sustainment Management System implementation across CONUS, Europe, and Honduras (July 2025, with Cegg LLC, Colorado Network Staffing Inc., and Amgg LLC supporting); and $22.6 million for Force Design Optimization Plans and Installation Master Plans across seven Marine Corps installations (September 2022, completion August 2026, with Klavon Design Associates, Tactica Management Services, Prosser Inc., and multiple staffing and support subcontractors).

HDR EOC competes in full-and-open territory with no set-aside posture. The division engages subcontractors across a broad spectrum—women-owned small businesses (Colorado Network Staffing Inc., Harris Miller Miller & Hanson Inc., Kimora Solutions LLC), service-disabled veteran-owned small businesses (Involve LLC, Amgg LLC, Alpha Facilities Solutions LLC), and 8(a) certified firms (Tactica Management Services LLC, Brice Solutions LLC)—reflecting federal small business utilization goals while maintaining prime delivery responsibility. On GSA Schedule work, HDR EOC offers 42 active labor categories ranging from junior environmental auditors at $56.69/hr to senior project managers at $201.62/hr, all requiring bachelor's degrees and no security clearances. SCI data (FY2022–FY2025) shows $15.7 million in invoiced revenue across 17 prime records, averaging 1.0–1.4 FTEs annually, with median government-paid rates around $381/hr and sub-hour engagement averaging 36% across contracts. The division deployed 36% of contract hours through subcontractors on SCI-reportable work, indicating a hybrid model balancing in-house delivery with specialized sub-expertise.

The parent company, HDR Inc., is a 100% employee-owned global professional services firm with over 12,000 employees and a long track record in infrastructure, environmental, and engineering sectors. Multiple named subsidiary entities under HDR serve distinct market segments; the EOC division focuses on environmental operations and construction within the defense and federal infrastructure markets. The corporate structure supports rapid teaming, as evidenced by frequent engagement of academic partners (Woods Hole Oceanographic Institution, Duke University, University of St Andrews, University of California San Diego, Cornell University) on marine science and environmental research tasks, and specialty firms (Robert D. Niehaus Inc. for housing market analysis, CSA Ocean Sciences Inc. for marine biology, Applied Research Associates Inc. for technical engineering) on technical subtasks. This architecture enables HDR EOC to position itself as an integrated prime while leveraging specialized small business and research institution partners to enhance delivery on complex federal environmental and engineering programs.
