Sources Sought Notice for a Model Support Replacement of the Unitary Plan Wind Tunnel

THIS IS NOT A REQUEST FOR PROPOSAL. NO PROPOSALS ARE TO BE SUBMITTED IN RESPONSE TO THIS NOTICE. The National Aeronautics and Space Administration (NASA) Ames Research Center (ARC)’s Unitary Plan Wind Tunnel (UPWT) has a requirement for a replacement model support system of the UPWT. The existing design works well but has worn out. Complete replacement is planned for two model supports, copying the original design. The piece parts will be purchased as part of this requirement. The parts require complicated machining and exacting tolerances. The largest and most complex parts (up to 99" long, 15.5" diameter, 1400 lbs) are to be made from the American Society for Testing and Materials (ASTM) A668 forgings. Some parts require precision grinding of bearing race lands to .0005” to .001” roundness and cylindricity. Contractor will be responsible for procuring forgings, material certifications, machining, grinding, heat treating, inspection reports, and shipping to NASA ARC. Final assembly will be done at NASA ARC by the tunnel mechanics, but interim fit checks of the mating parts could be done by the contractor as the work progresses. Each complete model support system requires over 122 parts. See ATTACHMENT 1, Draft Statement of Work (SOW) for more details. See attached drawings for the five items listed in Section 2.4.2 of the Draft SOW. Note that drawings A327-1826-M-31-1 and A237-1826-M31-2 are combined in the attached drawing A237-1826-M31.
