ITEM SUMMARY:
Booster Station #8, located at 1255 Helena Drive, is one of the City’s two booster stations, with associated ground
storage tanks, used to increase available water in the distribution system during peak demand periods. On April 5,
2021, the City Council approved Resolution No. 21-R-0022 authorizing the Mayor to execute a contract agreement
with Trotter and Associates, Inc. (TAI) of St. Charles, lilinois, for Phase | design engineering services related to the
Booster Station #8 Rehabilitation Project in an amount not to exceed $68,900. Trotter's original scope for design
engineering included:
Replacement of three existing 75 HP pumps and associated piping and valves.
Replacement of existing well control panels.
Replacement of generator controls.
Addition of variable frequency drives on the three new 75 HP pumps.
Replacement of pump starters in the existing motor control cabinet (MCC).
SCADA improvements to incorporate changes and upgrade Programmable Logic Controller (PLC).
Electrical system improvements/upgrades as determined necessary.
During Phase | design, the onsite generator was identified as needing replacement requiring additional
modifications to the building and electrical system. Additional out-of-scope work was required to meet revised
operations of the City’s Water System. The additional work performed by TAI during Phase | — Design amounts to
$18,900.00.
This project was placed on hold due to budget restrictions and material shortages for the specialty equipment
needed for rehabilitation (including pumps and the generator). Materials have become available for the project and
staff budgeted to move the Project to 2024. TAI has the relevant experience, familiarity and knowledge of the
Project. As such, staff requested TAI to provide Phase II bid assistance and Phase II|-Construction Engineering for
the Project. TAl submitted a proposal of $118,420.00. This proposal also includes the design overrun during Phase
|. The Project is tentatively scheduled for bidding in late 2024 with the goal of going to bid in 2024 and construction
in 2025.
In the FY2024, Water Distribution Fund 06-34-47-4806 has $113,000.00 budgeted for engineering services for this
Project. The overage of $5,420.00 can be supplemented by the same Fund. Staff recommends approving Trotter's
Amendment No. 1 in the amount of $118,420.00.
ACTIONS PROPOSED:
Approve Resolution No. 24-R-0067 authorizing the Mayor to execute Amendment No. 1 with Trotter and
Associates, Inc. of St. Charles, Illinois, for Phase Il and Phase III professional engineering services related to the
Booster Station #8 Rehabilitation Project in an amount not to exceed $118,420.00 for a Revised Contract Amount
