58 -- COMPACT RANGE REFLECTOR POC NASA Langley Research Center, MS 144, Industry Assistance Office, Hampton, Va. 23681-0001. In order that potential sources may learn of the interest in a specific requirement, an advance notice is published here. The requirement is for the fabrication, installation, and alignment of a blended-edge compact range reflector and support structure according to NASA Langley's design. The reflector will be a 26 ft x 26 ft offset fed reflector with a 13 ft x 13 ft parabolic center section and a cosine squared blended rolled edge. The focal length shall be 354 q 12 inches. The central parabolic section of the reflector shall have an installed surface accuracy of less than 2 mlls RSS, and the rolled edge shall have a surface accuracy of 3-6 mlls RSS. The installed reflector shall have uniform electrical conductivity across its surface with no intra-panel gaps. The contractor shall supply an error budget to include panel manufacturing tolerance, gravity errors, thermal errors, and alignment errors. The weight objective for the reflector and backstructure is less than 25,000 pounds. The reflector will operate in a controlled environment at 70x q 5xF, however, the assembly must also be able to survive temperature extremes of +40xF to +100xF without damage and without need for realignment. The surface accuracy of the installed reflector must be verified using photogrammetry. The reflector shall be completed within 12 months from contract award. The reflector shall operate, as a minimum, over the 0.30 to 18.0 GHz frequency range. The contractor shall have demonstrated experience in the design, fabrication, and installation of large rolled edge reflectors, with accuracies of 2 mlls RSS or better, that includes specific facilities that have been built and the performance verified by photogrammetric techniques. This procurement will be limited to contractors with proven capability as specified earlier. Firms that have the required specialized capabilities to meet the above requirements should submit appropriate documentation, literature, brochures, and references to demonstrate and support that they have the necessary experience and resources to successfully accomplish the described effort. This synopsis is for information and planning purposes and is not to beconstrued as a commitment by the Government nor will the Government pay for information solicited. Respondents will not be notified of the results of the evaluation. Respondents deemed fully qualified will be considered in any resulting solicitation for the requirement. Firms responding should indicate whether they are a socially or economically disadvantaged business firm, an 8(a) firm or a small business, and/or woman-owned business. The Government reserves the right to consider a small business or an 8(a) set-aside based on responses hereto. Closing date for submission of responses is 14 days from date of publication.
