Description

Further request to authorize the City Controller to disburse all funds related to this item. The additional expenditures will not exceed $333,000.
Report
Summary
This agreement provides land surveying and engineering Global Positioning System (GPS) equipment, software, maintenance, repair, training and support services for the Street Transportation Department. The equipment and services are required for survey field staff.
Additional funds are needed to allow the Street Transportation Department to purchase supplemental equipment and services for Continuously Operating Reference Stations (CORS) and network observations. This will allow a seamless integration with the survey equipment currently in use. The Trimble equipment we use currently is highly specialized and complex. All Trimble technology is proprietary and supported by no other equipment. In addition, matching equipment allows our existing data collectors to be able to run all City of Phoenix survey equipment. The new Trimble equipment will be used to make the conversion of City of Phoenix datum from National Geodetic Vertical Datum (NAVD) 1929 to the new National Geodetic Survey (NGS) 2022 datum. The CORS are an integral part of the new network to be built throughout the City. The CORS gives the City its own base station(s) from which to derive geometric mathematical solutions (X, Y and Z values) that are more accurate, precise and specific to our area of the planet. The decision to commence with the transition to the NGS2022 survey datum was made well after the original equipment purchase and, therefore, could not be included as part of the original procurement.
Contract Term
The agreement term is May 1, 2020 through April 30, 2025.
Financial Impact
