E-MAIL: Kimberly D. Duncan, k.d.duncan@larc.nasa.gov. NASA/LaRC plans to issue a Request for Quotation (RFQ) for a Research and Development effort on Development of Nonlinear Structural Analysis and Sensitivity Modules for a Coupled Computational Fluid Dynamics (CFD)-Finite Element Models (FEM) Analysis and Design Procedure. This procurement involves the development and implementation of approximate nonlinear FEM to describe the static response of composite, laminar-material, structural components. These computational models (for both analysis and sensitivity analysis with respect to material, size, and geometry) are to be coupled with nonlinear CFD analysis and sensitivity analysis codes to provide a multidisciplinary tool for smart nacelle analysis and design via active shape control. This requirement will be accomplished in two phases. The basic requirement for year 1 (analysis) and option 1 will be for year 2 (sensitivity analysis). This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/LaRC intends to purchase theitems from Old Dominion University Research Foundation (ODU), based on unique services available from only one source. ODU has gained unique knowledge and capabilities by performing on previous Grants, contracts, and purchase orders which related with the conception, initiation, development, and demonstration of 1-D, 2-D, and 3-D Simultaneous Aerodynamic Analysis & Design Optimization procedures and the formulations of 3-D direct-differentiation and alternate Simultaneous Aerodynamic & Structural Design Optimization procedures. All of these procedures are non-conventional optimization techniques utilizing high fidelity CFD and FEM approximations. ODU is the only source that has these unique experiences. It would require substantial duplication of effort and money in order for another source to perform this task, and these 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 February 23, 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.
