58 -- COMPACT RANGE REFLECTOR SYSTEM SOL 1-164-DIF.1102 DUE 040896 POC Ruth Kusterer, Contract Specialist, (804) 864-9355. Category 58 -- Compact Range Reflector System -- SOL 1-164-DIF.1102 DUE 4-8-96 POC Ruth Kusterer 804-864-9355 or e-mail r.a.kusterer@larc.nasa.gov. Quantity: 1 system -- Delivery: 365 days after date of contract award. FOB destination delivery. The proposal due date of 4-8-96 is approximate. Solicitation available approximately 3-8-96. All responsible sources may submit a bid which will be considered. 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. One or more of the items under this acquisition may be subject to Agreement on Government Procurement approved and implemented in the United States by the Trade Agreements Act of 1979. All offers shall be in the English language and in US dollars. All interested suppliers may submit an offer. An ombudsman has been appointed to hear concerns from offerors, potential offerors, and contractors during the preaward and postaward phases of this acquisition. The purpose of the ombudsman is not to diminish the authority of the contracting officer, the Source Evaluation Board, or the selection official, but to communicate concerns, issues, disagreements, and recommendations of interested parties to the appropriate Government personnel and to work to resolve them. When requested, the ombudsman will maintain strict confidentiality as to the source of the concern. The ombudsman does not participate in the evaluation of proposals, the source selection process, or the adjudication of formal contract disputes. Interested parties are invited to call the installation ombudsman Belinda Adams at 804-864-8989. Concerns, issues, disagreements, and recommendations which cannot be resolved at the installation may be referred to the NASA ombudsman Tom Luedtke at 202-358-2090. Before consulting with any ombudsman, interested parties must try to resolve their concerns with the contract specialist or the contracting officer. DO NOT CALL THE OMBUDSMAN FOR SOLICITATION REQUESTS/INFORMATION. (0057)
