CEIWR-HEC immediately set to work organizing and presenting training courses, the first of such kind in USACE, and initiating development of what later became to be the well-known family of CEIWR-HEC software. Early software packages were HEC-1 (watershed hydrology), HEC-2 (river hydraulics), HEC-3 (reservoir analysis for conservation), and HEC-4 (stochastic streamflow generation program). Within ten years after establishment, the technical field of planning analysis, the application of analytical methods to planning activities closely associated with hydrologic engineering, was added to the CEIWR-HEC mission. Over the years, CEIWR-HEC developed and published a number of technical methods documents addressing the full range of hydrologic engineering and planning analysis technologies. The format and content for technical short courses evolved early on and continues to be a mainstay of the CEIWR-HEC program. The family of software has grown to over twenty major pieces of software that are supported by a library of utility software, recent additions including GIS support. CEIWR-HEC is perhaps best known for these nationally and internationally renowned hydrologic engineering programs.CEIWR-HEC is organized into an Executive Office and three divisions: Hydrology and Hydraulics Technology; Water Resource Systems; and Water Management Systems. Staffs in all divisions undertake training, methods documentation, research and development, technical assistance and special projects. Notable recent achievements include: development of the next generation of successor CEIWR-HEC software (HEC-RAS, HEC-HMS, HEC-FDA, and HEC-ResSim); providing leadership in establishing risk analysis as the foundation technology for flood damage reduction planning and analysis; and development and deployment of the Corps Water Management System (CWMS), the real-time forecasting and decision-support system that is used 24/7 in execution of the USACE Civil Works water resource water control management mission.Description of Requirement: provide all personnel, management, supervision, equipment, material, tools, quality control, and other items necessary to provide water resource engineering and planning engineering software development; water resources data, methodologies, tools and models; training services; analysis and assessments; and studies for the Hydrologic Engineering Center (HEC).Typical services will include development on the following software programs:River Hydraulics: HEC programs HEC-River Analysis System (RAS), Sediment Transport, and RAS MapperHydrologic Analysis: HEC programs HEC-Hydrologic Modeling System (HMS) and HEC-Meteorological Visualization Utility Engine (MetVue)Hydrologic Statistical Analysis: HEC programs HEC-Statistical Software Package (SSP)Reservoir System Analysis: HEC programs HEC-Reservoir System Simulation (ResSim)Data Storage: HEC programs HEC-Data Storage System (DSS) and HEC-DSSVueFlood Risk and Consequence Analysis: HEC programs HEC-Flood Damage Reduction (FDA), HEC-Flood Impact Analysis (FIA), and HEC-Watershed Analysis Tool (WAT)Environmental Analysis: HEC programs HEC-Regime Prescription Tool (RPT), HEC-Ecosystem Functions Model (EFM), HEC-EFM Plotter, HEC-GeoEFM, HEC-EFMSim, and Water Quality Modeling.Miscellaneous improvements to other software packages.To be eligible for award, offerors must be registered in the System for Award Management (SAM) database.
