This requirement is to conduct a comprehensive engineering study of the current microearthquake (MEQ) network. The contractor shall perform a complete site survey and analysis of the existing network, which includes approximately 15 permanent seismic monitoring stations, 1 temporary seismic monitoring station, the Joshua Ridge repeater site, and the central data acquisition and processing site at the Navy Geothermal Program Office (GPO) office building at NAWSCL.
