HDR ENGINEERING, INC.

HDR ENGINEERING, INC. specializes in civil, structural, and hydrologic engineering services for critical infrastructure projects, with deep expertise in dam safety, flood control systems, and military construction design. The firm delivers full-cycle engineering solutions—from preliminary analysis and hydrologic modeling to detailed design and construction support—particularly for water resource systems such as reservoirs, levees, and dam operations. Their technical proficiency includes advanced river modeling using HEC-RAS, paleoflood analysis, reservoir simulation, and hydraulic infrastructure planning for high-risk environments. A key differentiator is their ability to integrate complex hydrologic data with long-term operational manuals, ensuring regulatory compliance and resilience in dynamic watershed systems. The contractor maintains a consistent and exclusive relationship with the Department of Defense, providing engineering services to the U.S. Army Corps of Engineers and other defense installations. Their work supports military construction projects including aircraft maintenance facilities, as well as civil works initiatives aligned with defense infrastructure needs, such as flood risk mitigation near bases and water control system modernization. This sustained engagement reflects a trusted partnership in delivering mission-critical infrastructure under stringent federal standards. HDR ENGINEERING, INC. operates primarily within NAICS 541330 (Engineering Services), with secondary work in scientific consulting and hydrologic research. Their market positioning centers on water resource engineering for federal defense and civil infrastructure, distinguishing them through specialized knowledge in dam safety, river system analysis, and design-build delivery for high-stakes public works. They bring precision to complex hydraulic environments, often addressing legacy infrastructure challenges with data-driven modeling and adaptive design solutions. Headquartered in Folsom, California, HDR ENGINEERING, INC. is a small business structured as a 2L entity with no federal certifications. Their geographic focus aligns with Western U.S. water infrastructure needs, particularly in California’s major river basins, while their defense portfolio extends nationally to military installations requiring robust engineering support.
