SUBJ: Approve Professional Services Contract with AE2S Construction, LLC for
SCADA Improvements — Project No, 14 -04
PROPOSED MOTION
"The City Council approves a professional services contract with AE2S Construction,
LLC for SCADA improvements in the amount of $272,312.00."
City Council approval requires a simple majority vote of the City Council present.
The City's Utility Supervisory Control and Data Acquisition (SCADA) system is designed to
automate the management of the wells, towers, lift stations, pumps, and any other items in the
water distribution and sanitary sewer system. The systems use telemetry units to relay
information back to a main computer system which checks if the system is functioning
properly.
As discussed at the April 12, 2004 work session, the City's current SCADA system is
antiquated, difficult to expand upon, and routinely gives false alarms. The current system is
very expensive to maintain and requires a substantial amount of staff time to check false
alarms and keep the system operational. Staff feels the existing SCADA system should be
replaced at this time. The proposed improvements will replace the software at the remote
sites and upgrade the SCADA software at the plant to communicate with the remote sites.
The project does not replace the SCADA system that operates the east water treatment plant.
It is planned that the SCADA software that runs the east plant be upgraded if and when the
west treatment plant is constructed.
Quotes for professional service for software and programming were received on Friday,
January 15, 2016. Barr Engineering drafted the specifications and has tabulated the quotes
and finds them accurate. Barr Engineering recommends award of the contract to AE2S
Construction, LLC.
