Description

NASA/LaRC plans to issue a Request for Quotation (RFQ) to process a modification to existing purchase order number L-10640 to add additional requirements to: 1) validation studies for grid selection for supersonic, turbulent boundary layer flow on a flat plate, 2) validation studies for improved code parallelization and possible reformulation of the time integration, 3) validation studies in the absence of shocks to improve some deficiencies in previous simulations of a similar flow for the period of award through September 30, 2001. There will be one option period: October 1, 2001 -- September 30, 2002 to 1) analyze simulation results for supersonic flow field without a shock, 2) initiate supersonic boundary layer flow simulation with impinging shock, 3) analyze simulation results for supersonic flow field with a shock. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/LaRC intends to purchase the items from the University of Rome, unique supplies available from only one source. The University of Rome has the expertise needed to perform this task. They have developed a weighted-essentially non-oscillatory (ENO) numerical scheme which is necessary in order to compute flows of interest in the proposed work. This requirement is a continuation of an existing purchase order. They have optimized the numerical procedure to be used in the proposed work and this optimization is a mandatory requirement for successful completion. Further, there would be substantial duplication of cost for another contractor to perform this requirement, 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 January 22, 2001. 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.
