A RESOLUTION OF THE UNITED CITY OF YORKVILLE, KENDALL COUNTY,
ILLINOIS APPROVING A CHANGE ORDER RELATED TO THE YORKVILLE
NORTH RECEIVING STATION PROJECT
WHEREAS, the United City of Yorkville (the "City") is a duly organized and validly
existing non home -rule municipality created in accordance with the Constitution of the State of
Illinois of 1970 and the laws of the State; and
WHEREAS, the City has approved a contract in the amount of $6,786,500 ("Original
Contract Amount") with Whittaker Construction and Excavating, Inc. ("Whittaker"), for a project
commonly known as the Yorkville North Receiving Station Project (the "Project"); and
WHEREAS, the Mayor and City Council ("Corporate Authorities") had previously
approved a change order that decreased the Original Contract Amount in the amount of
$227,995.23, to a total cost of $6,558,504.77 ("Revised Contract Amount"); and
WHEREAS, the price of the contract has since increased from the Revised Contract
Amount in the amount of $141,680.60 (the "Second Change Order") due to various changes,
including a change in the HVAC equipment required to complete the Project, the cost of an
additional component needed to complete the connection between existing and proposed piping at
the Project, and modifications to the building's foundation, required due to soil and groundwater
conditions that have been encountered during construction of the Project; and
WHEREAS, the total contract price after approval of the Second Change Order would be
$86,314.63 less than the Original Contract Amount; and
WHEREAS, all change orders increasing or decreasing the cost of a public contract by at
least $25,000 must meet the required findings that circumstances necessitating the change were
not reasonably foreseeable at the time the contract was signed; or the change is germane to the
Resolution No. 2026-42

original contract as signed; or the Change Order is in the best interest of the City as required by
Section 33E-9 of the Illinois Criminal Code (720 ILCS 5/33E-9); and

Change Order increasing the total contract price to the amount of $ 6,700,185.37 is in the best
interest of the City.

Agreement Date: July 17 2025
NAME OF PROJECT: North Receiving Station
OWNER: United City of Yorkville
CONTRACTOR: Whittaker Construction & Excavating, Inc.
The following changes are hereby made to the CONTRACT DOCUMENTS:
PCO #4 MAC Modifications — Dampers]: The mechanical dampers were all
specified as galvanized steel for the application in the Receiving Station. During
submittal review after discussion with the City, it was proposed by the Contractor and
the City requested aluminum dampers in the chemical feed room, and it was determined
to include additional protective finished coating for these components in addition to the
manufacturer's standard coating. Both of these are to provide additional corrosion
protection and resistance, and help improve the useful life of the equipment. The
proposed change order (PCO) includes the cost for making these changes for the
associated equipment. (Add: $1,539.06)
PCO #5 (Site Pipinq Modifications): Adjustments were made during construction to
the overall site piping phasing plan and layout, for modifications to the existing site
piping necessary for construction of the improvements after award of the project. One of
the modifications required included installing an additional 16-inch sleeve with stainless
steel bolts that was necessary to connect proposed water main to existing at a tee
connection, because of the configuration of the existing water main and proximity of the
bell of the existing piping to the new connection. (Add: $2,264.56)
PCO #6 (Receivinq Station Foundation Modifications): After excavation for the
foundation of the new Receiving Station Building, soil and groundwater conditions were
different than anticipated and designed for in the original structural design based on the
initial geotechnical investigation. This led to concerns with the ability of the lower -level
foundation and walls, as designed, to prevent groundwater infiltration and function as
intended for the building. The design for the foundation was modified including updated
drawings and details to incorporate the following modifications that were determined to
be required to provide the City with the optimal foundation to function as intended-
1 , Thicker concrete foundation slab (increase from 6" to 12" slab)
2. Overexcavation and backfill for the foundation (122 total cubic yards (CY), 50 CY of
which was included in the base contract
3. Installing rebar in the foundation slab instead of wire wound fabric originally intended
4. Adding membrane waterproofing on the exterior of the foundation walls in lieu of
waterproof admixture originally included in the concrete
5. Additional contractor time, material, and equipment for the lower -level redesign

6. Two -month time extension for procuring additional materials and modified
construction of the foundation
The PCO includes the contractor's additional labor, equipment, and
materials associated with the above modifications that were determined to be required
for the foundation, and include credits for the items associated with construction of the
original foundation design. (Add: $196,880.00)
PCO #7 (Credit for Eliminating Orthophosphate Chemical Feed System): The City
currently treats finished water at its existing well water treatment plants with corrosion
control. The City's Optimal Corrosion Control Treatment (OCCT) Study, required by the
IEPA for switching the City's water source, was in progress at the time of design and
bidding for this project. It was assumed that a similar corrosion control treatment using
an Orthophosphate Chemical Feed System, which is what the City of Chicago currently
utilizes for corrosion control in its distribution system and in the water that DuPage
Water Commission (DWC) delivers to its customers, would be required. The system, if
required, would have allowed for the City to add additional corrosion control at the
Receiving Station, to supplement/boost the level being delivered by DWC before
entering the City's distribution system. These components were included in the
Receiving Station.
The testing and analysis of the City's OCCT Study was completed at the end
of 2025, and the final report submitted to IEPA in early 2026, and the results indicated
that the corrosion control treatment provided through the delivered water/DWC was
adequate to maintain effective corrosion control throughout the City's distribution
system. The City does not need to add and maintain an additional supplementary
corrosion control chemical feed system, and after discussions with Staff, it was
determined to eliminate the Orthophosphate Feed System and associated equipment
and appurtenances from the project. (Credit: $59,003.02)
