B -- CASE STUDIES FOR THE SIMULATION OF HUMAN EXPOSURE TO PARTICULATE MATTER (PM) IN A ROADWAY MICROENVIRONMENT SOL PR-NC-99-U2F208 DUE 080699 POC Starry M. Jones, Contract Administrator, (919)541-2897 or Julio Lopez, Contract Specialist, (919)541-4470 WEB: ERROR --, jones.starry@epa.mail. The U. S. Environmental Protection Agency (EPA) intends to negotiate a sole source procurement with Fluent Incorporated, 10 Cavendish Curt, Lebanon, NH 03766-1442, for the acquisition of a contract to provide specialized set up and support for developing and evaluating applications of the Fluent Incorporated Computational Fluid Dynamics Software (CFD) in support of the EPA program. The EPA has a Silicon Graphics Incorporated (SGI) Onyx2 supercomputing workstation with Fluent Incorporated CFD Software installed. EPA is using this workstation and software to research and develop models of human exposure microenvironments. The Fluent Incorporated CFD software is very specialized numerical simulation and graphics software. There is a need to fully evaluate and modify the Fluent software to provide specialized set up for source characteristics and simulation of human exposure for best performance in a roadway microenvironment. Only Fluent Incorporated can fully evaluate specialized set up and modifications to their proprietary source code. This project will provide demonstration case studies using Computational Fluid Dynamics (CFD) software on supercomputing workstations for simulating the pathway for human exposure to Particulate Matter (PM) in a roadway microenvironment. EPA believes that Fluent Incorporated is the only company cable of satisfying the requirement stated above. All interested parities who believe they can provide the required servics should fully explain their capabilities in writing within 15 days of the date of this announcement. No Solicitation is available. The intent of this synopsis is to determine if any sources (s) exist and, therefore, no RFP is available. Consequently, any response(s) failing to provide the aforementioned data but instead choosing to merely submit a routine letter requesting a copy of the RFP will be ignored. Submit response to the U.S. EPA, Attn: Starry M. Jones (MD-33), Contracts Management Division, Research Triangle Park, NC 27711. No telephonic or faxed request will be honored.
