COUNCIL AGENDA MEMO - July 23, 2013 DEPARTMENT: Public Works AGENDA ITEM: Approval of purchase of a land survey base station and associated equipment from Allen Instruments and Supplies in the total amount of $40,757.08 using Arizona State Contract pricing. Summary This item is for purchase of one Trimble Net9 Ti-2 Reference Base Station Receiver with Zephyr Geodetic 2 Antenna, one Trimble R10 Integrated GNSS (Rover) Receiver System, associated accessories, and extended hardware and firmware maintenance warranties from Allen Instruments & Supplies. The existing base station is being traded in for a credit toward the purchase of the new base station. The purchase is through an existing Arizona State Contract. Background The Federal Communications Commission (FCC) implemented a narrow -band radio frequency mandate affecting all VHF and UHF Public Safety and Industrial/Business Land Mobile Radio systems with an implementation date of January 1, 2013. The federal narrow -banding mandate is an effort to ensure more efficient use of the VHF and UHF� spectrum by requiring all. Public Safety and Industrial/Business Land Mobile Radio (LMR) systems to migrate to 12.5 kHz efficiency technology. The survey equipment radio frequencies used by the City fall under this federal mandate. Public Works' existing base station receiver was purchased in 1999 and has far exceeded its operational service life. Two of three existing rover units were reprogrammed to be narrowband compliant; the third rover unit cannot be reprogrammed due to hardware limitations and is therefore unusable. Three rover units are in use on a regular basis in the Engineering and Water and Sewer Divisions. The one new rover unit will support current surveying tasks / projects within Public Works with capabilities that far exceed the existing base receiver's performance.
