District Context & Mission Impact
This long-term water management software and engineering contract is administered by the U.S. Army Corps of Engineers Humphreys Engineer Center Support Activity (HECSA), located at Fort Belvoir, Virginia. HECSA executes specialized contracting support for USACE specialized national centers, including the Hydrologic Engineering Center (HEC) and Institute for Water Resources (IWR). USACE relies heavily on cutting-edge software suites—such as HEC-RAS, HEC-HMS, and HEC-ResSim—to model river hydraulics, flood risks, watershed hydrology, and reservoir system management nationwide. Upgrading software code, refining water quality data models, developing analytical decision-support tools, and delivering advanced technical training ensures federal water resource managers and emergency responders make scientifically sound infrastructure decisions through 2031.
Contractor Spotlight & Industry Context
The selected contractor pool features premier environmental science, water modeling, and engineering organizations:
- Limno-Tech Inc. (Ann Arbor, MI)
- Research Triangle Institute (RTI International) (Durham, NC)
- Resource Management Associates (RMA) (Davis, CA)
- WSP USA Environment & Infrastructure Inc. (Blue Bell, PA)
Bids were solicited via the internet with five competitive proposals received. Delivering software development, ecological modeling, and hydrologic tools for USACE requires deep expertise in computational fluid dynamics, spatial geospatial analysis, water resource economics, and cloud-enabled data systems. Establishing a $26.2 million shared IDIQ framework enables USACE engineering teams to issue task orders for complex water planning studies and software modernizations rapidly.
