Description

THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR DIODE TUNABLE LASER. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to clarify justification for sole source procurement. FAR Part 6.302-1 (a) (ii) states that supplies may be deemed to be available only from the original source in the case of a follow-on contract for the continued development or production of a major system of highly specialized equipment, when it is likely that award to any other source would result in substantial duplication of cost to the Government that is not expected to be recovered through competition. New Focus programmable tunable diode lasers have been used for years in past laboratory testing of Bragg gratings at NASA Dryden and Langley Research Center. Archived strain measurements from thermal / mechanical static load ground testing will now be used as reference data for comparison of future flight measurements. System hardware consistency and confidence is critical in troubleshooting, evaluating, and characterizing structural strain measurements gathered from the Bragg gratings (optical strain sensor). Changing the tunable laser system at this point of the research will inject an additional variable in the analysis of flight data. It is desired that analysis of flight measurements and any anomalies be restrained to fiber / sensor issues. These issues would include variations in fiber lot characteristics, strain transfer issues due to the attachment method used on different substrates, vibration, sensitivity changes and sensor output component due to temperature changes (apparent strain), etc. Replacing the manufacturer of the tunable laser at this point will also require a considerable amount of redesign (interface codes, software drivers, and hardware peripherals) along with additional ground testing, all at NASA's expense. The dollar amount for new hardware and the man-hours required for system redesigns, new software codes, and replicated ground tests would be extensive. The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on May 16, 2001. Documents related to this procurement are available over the Internet and are in Microsoft Office 97 format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
