99 -- DIGITIZER MODULE CAPS, SURFACE DIGITIZING MODULES WITH GPS SATELLITE TIME CODE RECEIVERS AND COMBINER-REPEATER MODULES FOR USE IN EARTHQUAKE MONITORING STUDIES. SOL 99D88332088 DUE 091799 POC Sue Trujillo by fax (303)445-6345 WEB: AAMS Current Solicitation Listing, http://www.usbr.gov/aamsden/. E-MAIL: Sue Trujillo, d7810@do.usbr.gov. The Bureau of Reclamation intends to negotiate on a sole source basis with Digital Technology Associates, Inc. to acquire five Guralp CMG-DM24/3 Digitizer Module Caps, seven Guralp CMG-Dm16-S8 Surface Digitizing Modules with GPS satellite time code receivers, and four Combiner-Repeater Modules for use in earthquake monitoring studies. The digitizer caps will be installed directly on top of the Guralp CMG-40T broadband velocity three-component seismometers to fit into the Bureau of Reclamation's existing standard seismometer vault systems. The digitizing caps must have a waterproof fit to the seismometer and must be capable of providing regulated +12V and -12V power to the seismometer. The digitizer must provide interfaces and software to accomplish precision time keeping with a GPS receiver to an accuracy of 10 ms or better and provide 4MB of memory storage to stage data for uploading. The digitizers will provide 24-bit sampling of the seismometer signals, event triggering capability, electronic signals to center the seismometer masses, and perform 24-bit digitizing of the three differential 10V peak signal outputs of the seismometer and a 115 kbaud serial interface and firmware to provide a packet protocol data stream compatible with the Windows 95/NT Scream and Earthworm seismic interface and processing software packages. The firmware must support digitizing at sample rates of 1 sample/s to 100 samples/s. The Government believes that only one responsible source can provide the supplies that will satisfy the agency requirements. A Justification for Other than Full and Open Competition has been prepared in support of this acquisition. Firms that can provide the required items described above are encouraged to identify themselves and give written notification to the Bureau of Reclamation. This notice is not a request for competitive quotes. All responses received within 5 days of the date of publication of this synopsis will be considered by the Government. A determination by the Government not to compete this proposed action based on responses to this notice is within the discretion of the Government. Information received will be considered solely for the purpose of determining whether to conduct a competitive procurement. Inquiries will only be accepted by FAX at (303)445-6345, Attention: Sue Trujillo. Posted 09/13/99 (W-SN379660). (0256)
