Title
Ravinia Avenue South Extension, Phase II Design Engineering, Contract Amendment, Supplement #1
History
On June 16, 2025, the Village Board awarded Ravinia Avenue South Extension, Phase II Design Engineering to V3 Companies, Ltd. (V3) for the design engineering services to extend Ravinia Avenue south of 159th Street and connect it to LaGrange Road at 161st Street.
The design engineering contract is proposed to be amended to include the design of a median closure and left-turn lane extension at the west leg of the intersection of 159th Street and LaGrange Road. The desire to extend the turn lane and close the median arose as the Village evaluated overall traffic operations in the area and through coordination with IDOT. The existing left-turn lane does not provide sufficient storage and this condition is expected to be exacerbated by continued development in the surrounding area.
Financial Impact
The fee for additional services provided in the proposed Supplement #1 is $62,236.00, based on an hourly, not-to-exceed structure. There are sufficient funds in the FY2026 Capital Budget for this scope of work.
Recommended Action/Motion
I move to approve and authorize the execution of Change Order #1, Addendum A to the Professional Services Agreement with V3 Companies, Ltd. of Woodridge, IL for the Ravina Avenue South Extension, Phase II Design Engineering contract to increase the total not-to-exceed contract amount by $62,236.00 for the additional scope of services outlined in the attached Supplement #1 proposal for a revised total not-to-exceed contract amount of $308,907;
AND
Authorize the Village Manager to execute all related contracts, subject to Village Attorney review.
