E-MAIL: Kimberly D. Duncan, k.d.duncan@larc.nasa.gov. NASA/LaRC plans to issue a Request for Quotation (RFQ) for the development of methods to accurately predict the solution of the time-dependent Navier-Stokes (NS) equations in situations where massive flow separation exists. The Contractor shall, at a minimum, focus on the development of the Detached Eddy Simulation (DES) model and the implementation of the DES model into existing 3-D NS Solvers. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/LaRC intends to purchase the items from Boeing Commercial Airplanes. Boeing has unique knowledge available from only one source. Boeing Commercial Airplanes has recently developed the DES turbulence model and is therefore uniquely qualified to assist in the implementation and development of the NS solvers. No other offeror has the knowledge and experience of Boeing Commercial Airplanes regarding application of this method. It would take extensive time and money for someone else to obtain the knowledge base to perform these tasks, and such costs are not expected to be recovered through competition. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on April 20, 2000. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
