- Description
- United States Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), Central Region Acquisition Division, (CRAD) intends to negotiate on a sole source basis with Vaisala, Inc., 10 D Gill St., Woburn, MA 01901-1721 for Five Hundred Fifty (550) probes/DTT1 transmitter assemblies over a five year period. The Automated Surface Observing System (ASOS) automatically collects weather data and provides accurate, 24-hour accumulated weather reports to local weather observers; weather forecasters airport personnel, including pilots and air traffic controllers (ATC's); and Federal Aviation Administration (FAA) and National Weather Service (NWS) personnel. The current ASOS Dewpoint reporting sensor is the Vaisala DTS1 Dewpoint Temperature Sensor. The DTS1 Probe/Transmitter Assembly (S100-2MT4-3A1A1) is the primary assembly of nine field replaceable assemblies in the DTS1 electronics enclosure. DTS1 Probe/Transmitter is a proprietary Vaisala assembly that measures relative humidity (RH) and temperature and calculates dewpoint temperature. The DTS1 Probe/Transmitter performs extensive self-diagnostics and measures its own internal temperature to control the internal heating of the electronics enclosure. The Transmitter itself monitors a unique HUMICAP transducer that is a capacitive thin-film polymer with hygroscopic properties and a temperature sensor. The transmitter interprets changes in capacitance of the transducer, however as the polymer becomes saturated with water molecules, capacitance measurements become increasingly difficult. To compensate for this difficulty, for measurements above 93%RH, the thin-film polymer is heated and the heat enthalpy with respect to water, saturation pressure and other variables are used to calculate the dewpoint using standard and Vaisala proprietary equations. The COTS Vaisala DTS1 Probe/Transmitter power monitoring and control function was specifically modified to be compatible with the ASOS software communications. Because the Vaisala DTS1 Dewpoint Temperature Sensor has been subject to multiple seasons of testing to ensure the reporting precision and accuracy required for aviation and climatology per the ASOS Specification, and is a unique vendor proprietary system that was specifically modified for ASOS, Vaisala is the only known source of supply. To acquire any other manufacturers? transmitter will require extensive software re-development and hardware integration, as well as an extensive integration and testing efforts at considerable costs that cannot be recovered by the Government through open competition. If the DTS1 probe/Transmitter Assembly (S100-2MT4-3A1A1) is not available as a logistics spare to sustain operational requirements, the ability to report aviation weather forecasts for aviation safety and operations as well as the climatologic record. The probes are to be purchased for the National Weather Service, National Logistics Support Center (NLSC). The Government intends to solicit and negotiate with only one source under the authority of FAR 6.302-1. This is not intended to be a competitive proposal. However, interested parties may identify their interest and capabilities by submitting a required qualifications statement. In order to be considered, firms must furnish detailed product data concerning their capability to provide the supplies that will satisfy the Governments needs. All proposals received within fifteen (15) days after the date of publication of this synopsis will be considered by the Government. Central Region Acquisition Division, requires that all Contractors doing business with this officer be registered with the Central Contractor Registry (CCR). No award can be made to a company not registered in CCR. For additional information to register in CCR, please access the following web site: http://www.ccr.gov. In order to register, all firms must have a Dun & Bradstreet Number. A Dun & Bradstreet number may be acquired free of charge by contacting Dun & Bradstreet on-line at https://www.dnb.com/product/eupdate/requestOptions.html or by phone at (800) 333-0505. Contractors should submit their Certification and Representations thru the on-line Business Partner Network (BPN). The BPN is the single source for vendor data for the federal government. Contractors are encouraged to go on-line at www.bpn.gov to complete its representations and certifications. Information received will normally be considered solely for the purpose of determining whether to conduct a competitive procurement. Any questions should be directed to Charlene Yaple, Contract Specialist, at 816-426-7531 or Fax No. 816-274-6977.
