Wastewater Department
SCADA Upgrades Project - Construction
To approve Change Order 1 to the SCADA Upgrades contract to Electrical
Installations, Inc. of Moultonborough, NH in the amount of $114,000. Funding
will be through: Department: 169 Wastewater; Fund: WERF; Activity: SCADA
Upgrades.
EIT Change Order
The SCADA Upgrades project is needed to upgrade the SCADA system,
including control panels, computers and programmable logic controllers (PLCs)
throughout the wastewater facility. Much of the system is the original installations
from 15 — 20 years ago. Recent advances in technology have made the existing
SCADA system obsolete and difficult to use.
This project was sent out to bid on August 31, 2017 and Electrical Installations,
Inc. (EIT) was the low bidder with a bid of $591,280 including an Alternate A.
They have been awarded this project with a signed contract dated 1/5/2018. This
Change Order will bring the new contract value to $705,280.
Part of the SCADA project involves programming SCADA into the new control
panel and testing of each PLC and control panel where upgrades were made.
Originally, this work was going to be done by the design engineer, Woodard and
Curran, but it was determined to be more cost effective to have it done by the
contractor. EI is qualified for doing the SCADA programming and has provided
this service previously for Nashua. They also completed all the SCADA
programming and upgrades for the Manchester Wastewater Facility. Manchester
also provided a favorable recommendation of EII on the work they completed
there.
