Memorandum
Your approval is requested to approve a professional services agreement with Perceptive Controls, Inc. in the amount of $272,750.00 for the Tertiary Filter Programmable Logic Controller (PLC) Replacement Project at the City's Wastewater Treatment Plant (WWTP).

The WWTP has a Process Information & Control System (PICS) to monitor and control treatment processes by computer throughout the plant. As part of the PICS, PLCs are used operate and control twelve sand filters used for tertiary treatment of the water. The four PLC panels in the Tertiary Filter Building were installed prior to 1999 and the existing PLCs are Allen-Bradley Model PLC 5/40E, which are now obsolete and expensive to maintain.

This project will replace the four existing PLCs and associated Input/Output (IO) modules, IO racks, terminal blocks and cabling system connected to the existing IO module. This work also includes programming the new PLCs utilizing the current PICS programming standard, and modifying or recreating tertiary treatment process screens, alarms and data logging to the existing Historian server.

In response to RFP No. 22-14, the City received five proposals which were publicly opened on March 3, 2022. Each of the proposals was evaluated based on the selection criteria listed in the RFP. The selection committee selected the top three firms and opened their fee proposals. The ranking of the top three firms following evaluations, including fee proposals, are as follows:

1. Perceptive Controls, Inc. $272,750.00
2. Commerce Controls, Inc. $307,006.00
3. Windemuller Electric, Inc. $299,975.00

WWTP staff reviewed the proposals, compared them to RFP No. 22-14 specifications and recommends that Perceptive Controls, Inc. be approved ...
