J -- MAINTENANCE, INSTALLATION AND REPAIR OF SEISMIC AND GPS INSTRUMENTATION SOL 98WRSS1000 DUE 043098 POC Contracting Officer Phyllis Michel, (650) 329-4163 E-MAIL: to contact the contracting officer via e-mail, pmichel@wr.usgs.gov. The United States Geological Survey (USGS) has an ongoing requirement for services to assist in installing and maintaining a seismographic network of short-period, broadband, and strong motion sensors, and a geodetic network consisting of Global Positioning System (GPS) antennas in southern California, with their supporting telemetry systems, and to manage and operate related computer systems. The USGS established and manages the networks for earthquake research. Data from the networks is monitored in real-time, processed, and archived using networked computers at the California Institute of Technology (Caltech) central site in Pasadena. Network currently includes about 280 components at about 170 remote locations in southern California that are returned to the central site via analog telemetry; radios, microwave, and commercial telephone lines; and approximately 30 radio repeater sites in the telemetry system and a multi-hop Motorola Star Point analog microwave system. Seismic network also includes about 210 components at about 35 remote sites with Quanterra and Kinemetrics K2 digital data loggers telemetered via spread-spectrum radios, analog microwave, commercial frame relay, and internet connections. The number of digital sites will increase during the term of the contract while analog sites will decrease. GPS network includes 20 sites and their supporting dial-out telemetry, and will grow to around 200 sites over the life of the contract. The USGS also requires computer systems and computer networking administration to support critical systems used to acquire and analyze the data. Computer systems include 15 VAX and Alpha VMS and 15 SUN Solaris computers and their installed software and peripheral devices, and local area network (LAN) and wide area network (WAN) hardware and software, all located in the Pasadena office. Contractor will provide adequate staffing to successfully perform the work. Contractor personnel will travel within southern California, often to remote desert and mountain areas whereharsh conditions may prevail. The USGS will provide suitable vehicles. Primary duty station will be the USGS office in Pasadena, CA, but Contractor may station some personnel at other locations in southern California. USGS will provide electronics test equipment and data analysis tools appropriate for the systems being maintained. Anticipated contract term one year plus four one-year option periods. A single contract is planned. Complete RFP is available from the contracting officer. All responsible firms may submit an offer which will be considered. See Note 26. (0071)
