66 -- TURBINE FLOWMETERS SOL 13-SSC-0-97-8 DUE 031497 POC Gregory Fletcher, Contract Specialist 601/688-2223; Contracting Officer, Harold G. Taulbee, 601/688-1640 E-MAIL: click here to contact the contract specialist via e-mail, gregory.fletcher@ssc.nasa.gov. NASA/SSC intends to issue a RFO for the acquisition of seven (7) each, highly specialized turbine flowmeters of varying size and high fidelity performance for testing in a world class aerospace ground testing facility. Turbine flowmeters from 3" to 16" will be measuring LOX, GOX, LH2, and GH2 and sometimes two-phase flows. One (1) each, 12" and 16" flowmeters will be rated for 720 psig; four (4) flowmeters sized 3" to 8" will be rated for 8500 psi. a 6" flowmeter will be rated for 15,000 psig. Flow rates will run from 6 GPM to 26,000 GPM in liquids and 22 to 3200 ACFM in gas. Operation at supercritical pressures up to 8500 psig in LOX and LH2 will be a norm for some of the flowmeters. Service media temperatures will vary from -423 degrees farenheit to 100 degrees farenheit. General requirements include but not limited to the following: .1% repeatability, self lubricating bearings, turndown ratios from 50 to 200:1, .5% linearity. .25% accuracy; 347 stainless steel rotors, and 316 stainless steel bodies exist for almost all flowmeters; calibrations may include 10 points in water at a single pressure to 20 points in air at two different pressures with exceptionally low and high flow rates; .08 to 315 lb/sec in gas. All prospective offerors must demonstrate at least 5 years experience in the manufacture of specialized turbine flowmeters including those operating in high pressure liquid oxygen service. In addition, firms must provide a list of previous customers (at least 10) and the depth of specialization required to meet their needs, (i.e., sizes, temperature ranges, pressures, cryogenics, gases, flow rates, and materials used in construction, etc.) The Scope of Work and Specifications will be included in the solicitation along with the Model Contract which will be issued within 15 days of this publication. Hard copies available only. All interested firms may submit a proposal which shall be considered by the Agency. A firm fixed price commercial item contract will be awarded in accordance with FAR Subpart 12, as supplemented by the NASA MidRange Pilot Test Program approved by the Office of Federal Procurement Policy on April 16, 1993. Transmission of requests by internet E-mail to gregory.fletcher@ssc.nasa.gov or by facsimile at 601-688-1141 are acceptable, but original signatures are required per the model contract instructions. 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, 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, Mr. Mark Craig at 601-688-2123. Concerns, issues, disagreements and recommendations which cannot be resolved at the installation may be referred to the NASA ombudsman, Mr. Tom Luedtke at 202-358-2090. (0045)
