A -- 7-MONTH EXTENSION TO CONTRACT NAS5-32332 FOR SPECIALIZED SCIENTIFIC AND TECHNICAL SUPPORT POC Mary Petkoff, Contracting Officer, Phone (301)614-5587, Fax (301)614-5619, Email Mary.J.Petkoff.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#61317-252. E-MAIL: Mary Petkoff, Mary.J.Petkoff.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal (RFP) for specialized scientific and technical support on a sole source basis to General Sciences Corporation pursuant to 10 USC 2304 (c)(1) -- Only One Responsible Source. This procurement will extend the period of performance under Contract NAS5-32332 for up to an additional seven months. The extension period will be from March 1, 2000 through April 30, 2000 with five (5), 1-month options. This extension is required to: (1) meet critical milestones within the Data Assimilation Office (DAO), Sounder Research Team (SRT), and the Laboratory for Hydrospheric Processes and (2) to allow for the consolidation of efforts with similar requirements within the Earth Sciences Directorate for the purpose of competition. This procurement is a continuation of specific specialized scientific and technical support that General Sciences Corporation provides to advance NASA programs by promoting the increase in scientific knowledge in the areas of data assimilation, general circulation modeling, retrieval of atmospheric parameters from satellite instruments, and the study of climate phenomena such as El Nino and monsoons. The DAO, SRT, and Laboratory for Hydrospheric Processes are committed to critical milestones regarding the delivery and/or processing of scientific data, software, scientific analysis tools, and computer resources during the period from March 1, 2000 through April 30, 2000. Conducting a competitive procurement during the 1999-2000 time frame, prior to expiration of the proposed extension identified in paragraph 1, would cause unacceptable delays to the affected missions/programs. The critical milestones include: 1) delivery of the SRT portion of the AIRS code to the Jet Propulsion Laboratory (JPL) in May 2000. The Atmospheric Infrared Sounder (AIRS) Science team at JPL is required to deliver the Version 2 Launch Ready System to the Earth Observing System (EOS) PM-1 team in June 2000; 2) delivery of the most recent version of the MPI-coded Goddard-EOS (GEOS) GCM, for the PM-1 system in June 2000; 3) development of a hybrid coordinate for GEOS to allow a multi-year stratospheric analysis by April 2000. This involves incorporating the hybrid coordinate within the ARIES/GEOS dynamical core, as well as generalizing the physics drivers, analysis interface, and output routines to allow for the coordinate change; and 4) development of a higher resolution surface PSAS analysis, including the underlying statistical parameters, capable of utilizing high resolution satellite surface wind measurements by April 2000. The support sought during this extension is a continuation of the work performed by General Sciences Corporation, under Contract NAS5-32332, and is only intended to continue until follow-on contracts are competitively awarded. The statutory authority for this sole source procurement is 10 USC 2304 (c) (1) -- Only One Responsible Source. However, companies who believe that they can provide these services without any detrimental impact to program schedules supported by this work, shall identify their interest and capabilities within 15 days after the publication of this synopsis. See CBDNet Numbered Note 22. Interested parties have 15 days from publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications /capabilities will be used solely for the purpose of determining whether or not to conduct a competitive procurement. Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete the proposed effort on a full and open competitive basis, based on the responses to this notice is solely within the discretion of the Government. An Ombudsman has been appointed. See NASA-Specific Numbered Note "B". The Government does not intend to acquire commercial items in accordance with FAR Part 12. See CBDNet Numbered Note 26.
