ITEM SUMMARY:
The City owns and operates Booster Station #4, located at 320 E. Forest Avenue, and Booster Station #8, located
at 1255 Helena Drive. These booster stations are used to increase available water in the distribution system during
peak demand periods. This is accomplished by signaling pumps at the booster stations to operate based on water
system pressure. As more water is required, the overall pressure drops in the water system. As this pressure drop
occurs, a signal is received from the Water Treatment Plant, calling for pumps to run and “boost” the water system
pressures by supplying more water. The pumps are supplied with pre-treated water from the ground storage tanks
located onsite. Some examples of when the booster stations are operational include filling the water towers or
supplying water during periods of high demand.
In 2019, the City hired KLM Engineering, Inc., to inspect all of our water storage tanks. During these inspections,
Booster Station #4 and Booster Station #8 were identified as needing maintenance and rehabilitation. Being the
most familiar with the repairs required and conditions of the storage tanks, KLM was retained by the City in April
2021 to provide design-engineering services related to the rehabilitation of the booster stations. KLM identified the
following improvements required at each site:
Booster Station #4
e Replacement of the tank’s roof. The current roof was installed in 1959 and is in unrepairable condition.
e Sandblast and repaint the tank’s exterior.
e Removal of obsolete equipment from within the interior of the tank (i.e., Cathodic Protection System, ladder safety
climb device, wood plank baffle wall, etc.).
e Sandblast and repaint the tank’s interior.
e Installation of a mixing system inside the tank to improve water quality.
e Installation of OSHA approved safety features.
Booster Station #8
* Sandblasting and repaint the exterior.
* Removal of obsolete equipment from the interior.
* Re-welding and repair of interior supports.
* Repainting the interior.
Installation of a mixing system to improve water quality.

* Installation of OSHA approved safety features.
The engineering design process for the booster stations was completed in October 2021. The Cleaning, Repairing,
& Painting Two 500,000 Gallon Ground Storage Reservoirs Project, was initially advertised in the Daily Herald on
November 1, 2021, and bids were opened on November 15, 2021. These bids were rejected because the low bidder
could not honor its bid.
In an attempt to get this work done within our FY2022 budget, staff re-bid the project with the work at Booster Station
#8 listed as an alternate. The revised project was advertised in the Daily Herald on November 22, 2021, and bids
were opened on December 7, 2021. Three bids were received (results below) with ERA Valdivia Contractors Inc. of
Chicago, Illinois, submitting the lowest responsible bid of $1,388,650. This cost is for rehabilitation of both booster
stations. The Engineer's Estimate of Probable Construction Cost was $1,455,000.

Engineer's Probable Estimate $1,455,000
Reference checks were performed on ERA Valdivia Contractors Inc. with favorable results. Therefore, it is staff's
recommendation that a contract be awarded to ERA Valdivia Contractors Inc. of Chicago, Illinois, for the Cleaning,
Repairing, & Painting Two 500,000 Gallon Ground Storage Reservoirs Project, in an amount not to exceed
$1,388,650 (Base Bid + Alternate 1). Within the FY 2022 Water Capital Improvement Plan, we have budgeted
$1,450,000 for construction and inspection services related to the rehabilitation of these structures.
There may be a modification in the final contract cost due to the price of steel. Due to recent market uncertainties
the price of steel has fluctuated greatly in the past year. In order to get the best material pricing for the City the
price of steel will be set upon project start. The bidder submitted a price for steel that was recorded on the date of
bid close. The price of steel will also be reviewed on the project start date. If the price increases, we will need to
issue a change order. If the price goes down, the contractor will provide a credit. All pricing and any changes in
cost are based upon the NYSE American Steel Index.
ACTIONS PROPOSED:
Approve Resolution No. 22-R-0005 authorizing the Mayor to execute a contract with ERA Valdivia Contractors Inc.,
for an amount not to exceed $1,388,650 (Base Bid + Alternate 1) for services related to the 2022 Cleaning,
Repairing, & Painting Two 500,000 Gallon Ground Storage Reservoirs (Booster #4 and Booster #8) Project.
COMMITTEE RECOMMENDATION:
The Infrastructure Committee voted 5-0 for approval.
