THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. This is Request for Proposals No. 99WRSS0015. The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular No. 97-13. This acquisition is non-restricted. Standard Industrial Classification Code is 3826, small business size standard is 500 employees. CONTRACT LINE ITEM: Liquid-Scintillation Counter for analysis of environmental levels of tritium, S-35 and C-14, quantity 3 systems. DESCRIPTION: The Liquid Scintillation Counters will be used to count environmental levels of radioactive isotopes, specifically for analysis of tritium and naturally-produced S35 to estimate ages of ground waters and residence times of lakes and of river and stream basins. System must be fully automated and capable of automatically changing samples using a cassette loading system compatible with presently-used counting systems, which uses 20 ml and 7 ml high-density polyethylene and glass vials. System must include a computer system with hard disc and floppy drive, color monitor and printer. Software must be capable of accepting user defined counting protocols, including adjustable blanking time at beginning of count, and ability to set up sample counting time. Software must provide spectral display of energy ranges used in counting. System must have an electrostatic controller. Counting system must have a temperature controlled refrigeration system to lower background and prevent degradation of samples. System must have a low level counting mode for reduced background in counting low activity samples. An anti-coincidence shield for the counting system to reduce background is required. System shall be capable of producing results with a one sigma uncertainty of 0.15 TU for samples electrolyzed at the US Geological Survey Tritium Laboratory and counted 1000 minutes. A monitor arm for the computer monitor is required. System will have user adjustable energy ranges for optimization of counting statistics. System must provide an opaque light-blocking cover for samples waiting for analysis. Software must provide spectral index of samples. Software must provide instrument performance assessment and save information to hard disc. User defined formatting of printout and disc storage of data is required. A linear spectralanalyzer with 4000 channels is required. Must have an automatic power recovery system for cases where power is restored after a temporary electrical blackout. All system components must be totally Year 2000 compliant. DELIVERY: FOB Destination to U.S. Geological Survey, Water Resources Div., Isotope Lab, 345 Middlefield Road, Bldg. 15, Menlo Park, CA. Offerors shall prepare proposals in accordance with FAR 52.212-1, Instructions to Offerors -- Commercial Items, and include completed FAR 52.212-3, Offeror Representations and Certifications -- Commercial Items. FAR 52.212-2, Evaluation-Commercial Items, is applicable; the evaluation factors are (a) technical capability of the item offered to meet the Government requirement, (b) price, and (c) offeror's past performance.
