About this opportunity
The U.S. Army Corps of Engineers (USACE) Institute for Water Resources Hydrologic Engineer Center (HEC) is seeking maintenance and support services for HEC-EFMSim, a Java-based software tool that simulates and tracks natural resource status under various environmental and management scenarios. The contract services include evaluating and classifying software issues, performing bug fixes, providing minor code modifications and enhancements, offering field support activities, attending meetings, and creating supporting documentation. Contractors must possess extensive software development skills with emphasis on civil engineering, water resources tools, environmental analyses, and specific expertise in hydrologic simulation, statistical analysis, and 1D/2D hydraulic simulation. The evaluation criteria focus on technical understanding, personnel qualifications, organizational management, and past performance, with non-price factors being significantly more important than price. This combined synopsis/solicitation was posted on August 4, 2025, with proposals due by August 27, 2025, at 4:30 pm Eastern Time.
The solicitation is unrestricted with no set-aside designation, making it open to both small and other than small businesses under NAICS code 541511 with a size standard of $34.0M. The previous contractor providing support for this software was GEI-RMA, though the government has not disclosed the contract value and indicates pricing is being competed. The contract spans 720 days and operates under a firm fixed-price structure, targeting specific deliverables including 40 issue classifications, 30 additional bug fixes (16 minor, 14 routine), 3 modifications or enhancements, 10 meetings, and 3 software enhancement documentation efforts. The contractor's professional staff must include engineers, mathematicians, and computer programmers with at least five years of experience and proficiency in tools like Bitbucket, Jira, and TeamCity. All source code and deliverables will be government-owned and maintained in government-controlled repositories.
