RPT, EFM Plotter, and EFM Mapper - Maintenance and Support for HEC Java Software related to Ecosystems

The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) is seeking commercial services for maintenance and support of three Java software applications related to ecosystems: HEC-RPT (Regime Prescription Tool), HEC-EFM Plotter, and HEC-EFM Mapper. The contractor will provide software development services including evaluating and classifying software issues, performing bug fixes, providing minor code modifications and enhancements, field support activities, meeting participation, and documentation support. Contractors must have extensive software development skills with emphasis on water resources engineering and hydrologic simulation, with staff possessing minimum five years of experience in engineering, mathematics, or computer programming disciplines. The evaluation will be based on technical understanding, personnel qualifications, organizational management, past performance, and price, with technical factors weighted more heavily than price. Proposals are due by September 5, 2025, and offerors must achieve at least a Green/Acceptable rating for the first three technical factors and a Neutral Confidence rating for past performance to be considered for award.

This procurement is unrestricted with no set-aside designation, making it open to both small and other than small businesses under NAICS code 541511 with a $34 million size standard. The previous contractor for these services was GEI-RMA, though there are currently no open contracts for this software maintenance work. The government has not disclosed the estimated contract value, indicating that pricing will be competitively determined through the solicitation process. The contract will be a firm fixed-price award with a 730-day performance period and specific deliverable limits including 45 issue classifications, 20 minor bug fixes, 15 routine bug fixes, and 23 minor modifications or enhancements within a 365-day performance timeframe. Most work will be performed at the contractor's facility, with virtual work options available for both local and non-local contractors.
