A -- FOUR-MONTH EXTENSION TO NAS5-31729 FOR ENGINEERING, TECHNICAL, AND DATA ANALYSIS SUPPORT TO LAB FOR ATMOSPHERES SOL RFO5-61932-272 DUE 053000 POC Michele Rook, Contracting Officer, Phone (301)286-4815, Fax (301)286-1760, Email Michele.C.Rook.1@gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.msfc.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=D&pin=51#RFO5-6193 2-272. E-MAIL: Michele Rook, Michele.C.Rook.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Offer (RFO), on a sole-source basis to International Development and Energy Associates (IDEA). This procurement will extend the period of performance under Contract NAS5-31729 for an additional 4-months beyond the current end date of the contract (7/30/00). This extension is required to meet critical milestones while a competition is conducted for the follow-on effort. Under Contract NAS5-31729, the contractor provides support to the Radiometric Calibration facility, Cassini, Total Ozone Mapping Spectrometer (TOMS), LIDARS, Subsonic Assessment (SASS), and other related projects in the Laboratory for Atmospheres. This support includes, but is not limited to, Radiometric laboratory testing; spacecraft command; power and data interface design and development; hardware and software development; system testing; flight support analysis; system engineering and technical support. During this extension period, the contractor shall complete the following critical milestones: 1) maintain continuity of the Radiometric Calibration facility used for the test and integration of Shuttle payload scheduled for calibration in September 2000; 2)continue mass spectrometer development scheduled for test in November 2000; and 3) deliver TOMS FM-5 engineering models to launch site in November 2000. IDEA (the current source of the required services) is the only responsible source with the specialized knowledge and experience required to perform the above requirements and meet the critical milestones. IDEA possesses unique knowledge and experience in the following areas: radiometric laboratory testing; spacecraft command; power and data interface design and development for planetary probes; hardware and software development; system testing; integration for upcoming Shuttle flight; system engineering; aircraft flight deployment; and technical and logistical support. No other known source can meet the above critical milestones. Award to any other source would result in unacceptable delays in thefulfillment of NASA Goddard's requirements. The statutory authority for this sole-source procurement is 10 U.S.C. 2304(c)(1) -- Only One Responsible Source. However, companies who believe they can provide these services without any detrimental impact to the program schedules supported by this work, should fully identify their interest and capabilities within 15 days after publication of this synopsis. 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. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. An Ombudsman has been appointed. See Internet Note "B". All qualified responsible sources may submit an offer which shall be considered by the agency.
