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. The CBD notice issued March 28, 2000 is hereby amended to read as follows: This procurement will be awarded under a Firm-Fixed Price Level-of-Effort, multiple award type contract. The basic effort consists of transport optimization activities at the first site; two additional phases of work, to be conducted at two additional pump and treat sites, may be awarded at the discretion of the Government. The initial period of performance will be determined shortly after award and any subsequent effort (at Phase II and III sites) will be determined prior to award of those phases. Award is scheduled for June 30, 2000. The objective of this project is to demonstrate the cost benefit of applying transport optimization codes to simulations of solute transport for existing pump and treatment systems which have been screened for optimization potential. The results of transport optimization will be compared to the results of hydraulic optimization that will be conducted independently by HSI Geotrans to determine what, if any, additional cost benefit is available with the use of transport optimization codes. 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 criteria to be used in selecting transport modelers is detailed in the Statement of Work. Upon completion of the optimization-simulation modeling, assistance will be provided to the site in implementing the suggested modifications to the pump and treat system to compare actual cost savings to the projected cost savings. 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; 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 03/29/00 (W-SN439118). (0089)
