RE:

GPS Rover Replacement & GPS Base Station Upgrade

 

Please include the following item on the City Commission Agenda for consideration at the February 25, 2014 meeting:

 

Approve purchase of a firmware upgrade for the existing Trimble GPS/GNSS Reference Receiver and two (2) Trimble GPS Rover/Data Collectors from Seiler Instrument in amount of $60,595.00 

 

Project Description:

This equipment is to replace two (2) existing Utilities GPS rovers/data collectors and related field equipment, as well as an upgrade to the city’s existing Trimble reference station located on the roof of City Hall. The recommended equipment will increase productivity of infrastructure data collection by allowing data to be remotely transmitted back to office staff from the field. The firmware upgrade to the City’s Trimble reference station is needed to bring the existing firmware current. The updated reference station in conjunction with the rovers will allow the use of a broader satellite network and better satellite availability when collecting data under trees and around tall buildings or obstacles. The recommended equipment will be used for collection of inventory infrastructure assets, system capacity analysis, and survey of CIP and public infrastructure projects. The existing GPS rovers and field equipment will be redeployed for use by other departments within the city that need survey grade GPS equipment.

 

Project History:

Department of Utilities purchased its current GPS rover equipment in March 2007, at which time the reference station on the roof of City Hall was also upgraded. Incremental updates to the GPS Rover’s software and hardware maintenance have been maintained as needed. In the past seven (7) years Utilities field staff collected 66,348 survey points, surveyed using the current equipment.

 

Project Details:

Department of Utilities will source the equipment from Seiler Instrument, the sole source provider for Trimble sales and service for the State of Kansas. Seiler Instrument is to provide; one (1) Trimble NetR5 GPS/GNSS reference receiver firmware, to include installation one (1) year on-site hardware, software, firmware warranty; two (2) Trimble R10-LT GPS/GNSS Receivers, two (2) Trimble TSC3 Data Collectors, two (2) Telescopic Rods w/Bipod, two (2) Hard Cases and related field accessories, cabling etc. Seiler Instrument will also provide on-site training to field and office staff and technical support for a period of one (1) year after date of purchase.

 

Project Funding:

This purchase will be funded by the Department of Utilities from the 2014 utilities operation and maintenance budget in the amount of $60,595. Additional warranty after the initial one (1) year warranty will be purchased at $1,195 per year for each GPS rover unit. Seiler Instrument will provide the recommended equipment at GSA equivalent pricing.

 

Action Request:

Approve purchase of a firmware upgrade for the existing Trimble GPS/GNSS Reference Receiver and two (2) Trimble GPS Rover/Data Collectors from Seiler Instrument in amount of $60,595.
