Hdr-Obg A Joint Venture

Hdr-Obg A Joint Venture, a partnership between HDR Engineering Inc. and Ramboll Americas Engineering Solutions Inc., serves as a prime contractor delivering architect-engineering and environmental remediation services to federal agencies, competing exclusively in full-and-open procurements with no socioeconomic set-asides. The joint venture operates from Kansas City, Missouri, and specializes in Superfund site investigation, remedial design, and construction oversight for contaminated sites across the Northeastern United States.

Hdr-Obg's customer footprint concentrates heavily with EPA Region 2 and the U.S. Army Corps of Engineers. EPA Region 2 accounts for 27 awards valued at $43.9 million combined potential value, while the Army Corps of Engineers Kansas City District anchors the portfolio with seven awards totaling $571.7 million in combined potential value—driven largely by two $225 million indefinite delivery contracts awarded in 2024 and earlier years that serve as parent vehicles for task orders. The Army Corps Philadelphia District and Tulsa District combined represent $4.3 million. This concentration by agency is stark: the Army Corps Kansas City District alone carries 92% of the joint venture's combined potential value, though the distribution by award count is inverted, with EPA Region 2 dominating task-order volume. Recent representative work includes a $4.863 million cost-plus-fixed-fee delivery order from EPA Region 2 for remedial design of the Raritan Bay Slag Jetty Sector Superfund site in Old Bridge, New Jersey (awarded September 2026, completion September 2031); a $4.3 million cost-plus-fixed-fee delivery order for remedial design and investigation at the GCL Tie and Treating Superfund site in Sidney, New York (awarded August 2025, completion August 2030); and a $3.817 million cost-plus-fixed-fee delivery order for remedial investigation and feasibility studies at the Kil-Tone Superfund site in Vineland, New Jersey (awarded July 2025, completion July 2030). All work is priced cost-plus-fixed-fee or firm-fixed-price, with no set-aside designations.

Hdr-Obg holds positions on three primary parent vehicles. The Architect-Engineer, Hazardous, Toxic, and Radioactive Waste and Environmental Services IDIQ, awarded by the Army Corps Kansas City District, carries 16 task orders worth $16.6 million combined potential value and supports EPA Region 2 and Philadelphia District environmental remediation work. The Kansas City Unrestricted A-E MATOC, also a $225 million vehicle from the Army Corps Kansas City District, has generated 11 task orders valued at $20.3 million. An earlier Indefinite Delivery Contract (W912DQ18D3010) has produced nine task orders worth $14 million. Performance locations span New Jersey, New York, and Pennsylvania, with all work focused on Superfund site assessment and cleanup in the Northeast.

Activity has grown modestly but unevenly. The joint venture received five awards in 2022, one in 2023, seven in 2024, seven in 2025, and four in 2026 through mid-September. Combined potential value across all 39 awards stands at $620.9 million, though only $35.1 million (6% of potential value) has been obligated. Eleven awards with combined potential value of $11.9 million face ultimate completion within the next twenty-four months, presenting recompete exposure at sites including Kil-Tone OU2 (February 2027), Vestal Water Supply Well (August 2027), and Helen Kramer Landfill OU2 (November 2027).

Hdr-Obg competes exclusively as a prime contractor; the source reports zero subcontract awards. The joint venture's portfolio concentrates entirely on engineer-architect services (39 awards) under PSC A-E codes, with work focusing on site investigation, remedial design, engineering during construction, and technical assistance at federal environmental remediation sites.
