Please note: This is a Sole Source Notification. Specifications include, but are not limited to: The Resilient Environment Department (RED) is seeking Sole Source Designation to procure the renewal of MIKE SHE/MIKE Hydro modeling software for an additional one-year term. MIKE SHE/MIKE Hydro is a proprietary software and DHi Water and Environment is the sole source provider of the software. MIKE SHE/MIKE Hydro is a hydrologic modeling software that supports and informs water management and future planning and policy decisions. Presently, the MIKE SHE/MIKE Hydro software is the best available tool for the County's needs with no other software capable of 1) simulating the complex canal structural operations in the surface water system; and/or 2) fully integrating the county's complex surface water components with the groundwater aquifer, which are highly connective due to the transmissive nature of the Biscayne Aquifer. There is currently no other tool capable of replacing the functionality offered by the existing County's MIKE SHE/MIKE Hydro model.
