ITEM SUMMARY:
The DuPage Business Park, located on the southwest side of the City of West Chicago, has seen major
developments over the past few years, which has resulted in an increased traffic volume. To protect the
safety of motorists, the City desires to install a traffic signal at the intersection of IL-38 (Roosevelt Rd)
and Technology Boulevard. The Illinois Department of Transportation has jurisdiction over IL-38, while
the City has jurisdiction over Technology Boulevard.
In 2020, State Senator Karina Villa, as part of the Public Act 102-0017, included improvements
associated with this traffic signal to be appropriated from the Build Illinois Bond Fund via the Illinois
Department of Commerce and Economic Opportunity. The cost associated with these improvements is
listed at $600,000.00.
On February 21, 2022, the City Council awarded a Contract to Gewalt Hamilton Associated, Inc. (GHA)
for engineering services related to Phase II — Design, which included the preparation of an intersection
design study, topographic survey, traffic signal installation plan, traffic signal interconnect plans, small
geometric improvements, and bidding assistance in the amount of $51,950.00.
The City received the Notice of State Award (NOSA) for the DCEO funding on June 5, 2023. Based on
the NOSA, a Grant Agreement should be forthcoming. Staff would like to begin the detail design of the
project and preparation of bid documents while awaiting the Grant Agreement. Change Order No. 1 for
$27,300.00 is required to prepare the necessary plans and bidding documents and also includes the
addition of the intersection lighting, which was not part of the original scope.
Staff recommends approving Change Order No. 1 to GHA’s original contract for the IL-38 and
Technology Boulevard Traffic Signal Project in an amount not to exceed $27,300.00. GHA’s change
order will be funded through available fund balance (08-34-53-4225).
ACTIONS PROPOSED:
Approve Resolution No. 23-R-0070 authorizing the Mayor to execute a Change Order No. 1 for the
Professional Engineering Design Services contract with Gewalt Hamilton Associates, Inc. for the IL-38
and Technology Boulevard Traffic Signal Project for an amount not to exceed $27,300.00
