Schnabel-Hdr Joint Venture

Schnabel-Hdr Joint Venture, a strategic partnership between Schnabel Engineering and HDR Inc., operates as a prime contractor delivering architectural and engineering services for infrastructure safety, risk management, and flood control to the U.S. Army Corps of Engineers on a full-and-open competitive basis, with no SBA set-aside designations across its federal footprint.

The joint venture holds a $75 million Indefinite Delivery/Indefinite Quantity contract with the Corps of Engineers awarded January 30, 2026, running through January 29, 2031, and a predecessor $60 million IDIQ (Architect Engineer Services for the Risk Management Center) under which it has executed over 30 delivery orders since 2021. Concrete capability work centers on dam safety analysis and reviews, levee safety assessments, flood risk modeling using HEC-RAS and advanced analytical tools, structural integrity evaluations, seismic analysis, extreme storm rainfall modeling, independent external peer reviews, technical training delivery, and development of guidance specifications and technical documentation. Representative delivery orders include a $7.54 million firm fixed-price order for dam safety base tasks and options (November 2024, ENDIST Tulsa), a $3.07 million order for base tasks supporting the Risk Management Center (September 2023, Louisville), a $2.07 million order for national levee safety work with options (September 2021, Louisville), and a $1.57 million order for National Levee Safety Program support (September 2021, Louisville). Recent smaller orders include a $437 thousand Safety Assurance Review at Whittier Narrows Dam, California (June 2025), a $286 thousand risk communications order for Arkabutla Dam, Mississippi (September 2025), and a $2.5 thousand delivery order for architectural engineering services (February 2026).

Customer concentration is extreme and singular: the Department of the Army Corps of Engineers accounts for 99% of combined potential value across 81 awards. Within the Corps, the Engineering District Louisville field office anchors 30 awards valued at $80.3 million, while the Corps' headquarters entity places 28 awards valued at $104.6 million combined. The Engineering Districts of Tulsa, Kansas City, Los Angeles, and other regions place smaller volumes. The joint venture sits on two primary vehicles: the predecessor Architect Engineer Services for the Risk Management Center IDIQ (29 task orders, $36.4 million combined potential value) and an older indefinite delivery contract W912QR16D0004 (48 task orders, $9 million combined potential value). A new $75 million IDIQ awarded in January 2026 positions the joint venture for sustained delivery-order activity through 2031.

Total awards span 81 delivery orders from 2015 through February 2026, with combined potential value of $190 million and combined obligated dollars of $35.3 million (19% of potential). Activity accelerated in 2024 (nine awards) after a slower 2022–2023 period (four and three awards, respectively), then dropped to two awards in 2025 and two in early 2026. Twelve awards (combined potential value $27.4 million) reach ultimate completion within the next twenty-four months, exposing the joint venture to recompete risk on approximately 15% of its pipeline by dollar magnitude. The joint venture competes in the open market without set-aside protection across all 81 awards. All work is performed at Schnabel-Hdr locations in Chadds Ford, Pennsylvania or Louisville, Kentucky, with performance also occurring at dam and levee sites nationwide (California, Mississippi, and subordinate District locations). Schnabel-Hdr engages specialized subcontractors including HR Wallingford Inc. for levee safety advisory services, Applied Weather Associates LLC for extreme storm rainfall analysis, Creative Circle LLC for training support, Lettis Consultants International Inc. for seismic and geological consulting, and Percell Taureau Consulting Corporation for structural engineering subject matter expertise. As a child entity of HDR Engineering Inc., Schnabel-Hdr Joint Venture operates within the HDR corporate structure while maintaining its joint venture partnership with Schnabel Engineering.
