Memorandum of Agreement-SCADA Upgrades and TRM List - Scope of
Work and Fee.
The Wastewater Plant has been using the services of Woodard Curran for
SCADA upgrades to the Wet Weather Facility due to their extensive
experience and expertise with SCADA systems at wastewater plants. Upon an
initial evaluation of the plant wide SCADA system, Woodard and Curran
determined the entire SCADA system is in need of upgrades. They have
broken down the SCADA upgrades over a period of 3 years, the first being
FY2016.
Woodard and Curran will initially perform SCADA upgrades that can be
performed in a short time frame or approximately 3 months, and are identified
in the attached TRM list. This work will significantly improve the existing
SCADA system reliability and backup. Their fee for these services comes to
$48,932. In addition, they will install a wireless SCADA network at 12 control
controls panels such that operators will be able to update their plant checks
with tablets. This cost comes to $33,000. Finally, they will do a complete
design of the control system and associated SCADA system. This work will
involve upgrading 13 control panels such that there will be uniformity of the
system components to allow for simplified operations, have less chance for
mistakes, standard maintenance and ease of parts procurement. This effort will
also involve upgrades to allow SCADA control for all control panels. The total
costs for this design effort comes to $106,568. The total for all three of these
upgrades comes to $188,500, and is part of the WERF list, Asset ID: SCADA.
The SCADA work will be completed over 3-years, the first year being
FY2016. Based on Woodard & Curran’s design effort, additional SCADA
upgrades will be identified for FY 2017 and FY 2018.
