DISCUSSION
The Long Beach Gas and Oil Department (LBGO) monitors surface elevations for oil field-related subsidence control through 12 permanent, City-owned Global Positioning System (GPS) base station receivers that collect data in real time. This information is augmented by the semi-annual mobile surveying of 240 GPS benchmarks, collected from five portable monitoring receivers. In 2009, LBGO conducted a technical evaluation of its Real-Time Network (RTN) and determined that the RTN software and equipment was in need of replacement. The current software was incapable of being upgraded and the receivers were beyond their intended service life. It was determined that the upgrade would take place in three phases:

§Phase 1: Software replacement
§Phase 2: Purchase of portable GPS receivers
§Phase 3: GPS base station receiver replacement

Phase 1 was completed on July 21, 2009, when the City Council approved Geodetic Inc., as the company to provide the GPS RTN Software.

LBGO would like to begin Phase 2 with the purchase of five portable Trimble R8 GNSS Receivers, hardware and related software from Allen Instruments and Supplies, plus $25,000 in available funds for any equipment repair needed for the next five years.

Allen Instruments and Supplies, located in Anaheim, CA, is the only authorized distributor in Southern California to sell and service the full line of Trimble Survey products and is the only local supplier of Trimble receivers that are compatible with the monitoring software.

This matter was reviewed by Deputy City Attorney Richard A...
