Title
AUTHORIZE THE MAYOR AND CITY MANAGER TO ENTER INTO A CONTRACT WITH BARR ENGINEERING FOR SCADA SYSTEM ENGINEERING SERVICES
Background
The City selected Barr Engineering (Barr) on March 2, 2017 to review our existing utility Supervisory Control And Data Acquisition (SCADA) system and make recommendations for its improvement. The result of that work was implementation of several high-priority interim improvements to our system.
Barr was then asked in a subsequent contract authorized on June 1, 2017 to continue their work and perform a Field Radio Study, determine the needs of a new communication network to improve the long term communication of our system, and audit the various sites to determine specific hardware upgrades necessary. The findings of the study, network design, and audit were presented to the City Council at their October 19, 2017 Work Session.
Current Work Proposal
Barr was asked to develop this proposal which will provide engineering support to bring the above recommendations to through their implementation. The services to be provided under this proposal include preliminary design (predesign), software integrator selection, preparation of construction plans and specifications (design), and bid administration for the Blaine SCADA system.
Construction phase scheduling will be developed cooperatively between the City and Barr during predesign and finalized during the design phase.
Financial Impact
The engineering services under this proposal are estimated at a not-to-exceed cost of $223,000. Funds will come from the Water and Sewer Enterprise Funds and future bond issuance as previously discussed.
Future Work
This proposal does not include construction phase services; a separate proposal for construction phase services will be prepared as the scope of the SCADA system is fully defined and construction scheduling is finalized. Included in the Technical Memorandum from Barr is a Draft Engineer’s Estimate of Probable Cost estimating that the construction phases for this work will be in the range of $2,830,000.
Recommendation
By motion authorize the Mayor and City Manager to enter into a contract with Barr Engineering for SCADA System Engineering services in the amount of $223,000.
