NASA/JSC plans to issue a Request for Offer (RFO) for the design, fabrication, testing and procurement of a water sublimator for X-38 crew cabin thermal control. This procurement is being conducted under the NASA MidRange Pilot Test Program approved by the Office of Federal Procurement Policy. NASA/JSC intends to purchase the items from United Technologies/Hamilton Standard. This is a sole source procurement due to the fact that no other companies have been identified with the technology needed for the X-38 sublimator. See numbered Note 22. The delivery date is 18 months after the award of the contract. Delivery is to be made to JSC, Houston, TX. There are 4 options. Option 1 requires the contractor modify the baseline sublimator mechanical design to withstand the SD negative case pressure which would be experienced should the sublimator be located inside of the pressurized cabin. Option 2 requires a modification of baseline LM-209-type sublimator design to add a second coolant passage in accordance with the SD. Option 3 requires modification of baseline LM-209-type design to add a third passage in accordance with the SD to be used for the purpose of evaporating an appropriate refrigerant to provide sea level cooling. Option 4 requires the contractor to conduct qualification random vibration testing on one unit. The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 15 days from publication on the Commerce Business Daily (CBD) to submit their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after 15 days without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not to compete this proposed contract, on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of the Government. Firm date for receipt of offers will be stated in the RFO. All responsible sources may submit an offer which shall be considered by the agency.
