B -- APPLICATION OF FLOW AND TRANSPORT OPTIMIZATION CODES TO GROUNDWATER PUMP & TREAT SYSTEMS SOL N47408-00-R-2113 DUE 042800 POC OxenderSK@slc.navfac.navy.mil WEB: N47408-00-R-2113 Application of Flow & Transport Optimization, http://esol.navfac.navy.mil. This procurement will be awarded under a Firm-Fixed Price Level-of-Effort, multiple award type contract with a base year and two additional phases that may be awarded at the discretion of the Government based on successful completion/results on the basic effort. The initial period of performance will be performed at a site to be determined shortly after award and any subsequent effort (Phase II and III) sites will be determined prior to award of the those phases. Award is scheduled for mid July 2000. The objective of this project is to demonstrate the cost benefit of applying flow (or hydraulic) and transport optimization codes for existing pump and treatment systems which have been screened for optimization potential. The Navy, Army, and Air Force will review the status of their pump and treat sites and select 12 for more in-depth investigations. These 12 sites will be screened using an updated version of the EPA's pre-optimization screening tool. Upon completion of the optimization-simulation modeling, assistance will be provided to the three sites in implementing the suggested modifications to the pump and treat system. This study will employ the MODMAN Version 4.0 hydraulic optimization code that was developed for the EPA by HSI Geotrans, and transport optimization code(s) that are to be selected by the project team. The hydraulic optimization modeling for this project will be conducted by HSI Geotrans; the criteria to be used in selecting transport modelers is detailed in the Statement of Work. It is intended that one or more of the transport optimization codes that are demonstrated to be successful will be incorporated into the Department of Defense Groundwater Modeling System. Technology transfer is a significant component of this project. Therefore, any transport code used on this project must be available for subsequent public use. The level-of-effort is anticipated at 932 hours for each phase. This acquisition is unrestricted and any request for a solicitation must be in writing (fax #805-982-3015 or through the internet). SIC Code is 8999. This RFP will be issued on or about April 28, 2000 with an estimated closing date of May 26, 2000. Posted 03/28/00 (W-SN438682). (0088)
