ChangeOrderNotice I-21-4744Elgin O'Hare Western Access I-294 to 1-90 East of I-294 at Grand Ave CMS

The Illinois State Toll Highway Authority is issuing a change order notice for contract I-21-4744 with STV Inc., increasing the Phase III construction management services contract by $995,000 effective November 3, 2026 (the close of the required 14-day public notice period). This is the second supplement to the original contract; the total authorization rises to $5.617 million from the prior interim value of $4.622 million.

STV Inc. provides on-site inspection, layout review, design change documentation, geotechnical inspection and testing, records preparation, pay estimate preparation, change order processing, and project closeout services for construction contract I-21-4736 (Railroad Bridge Construction over the Union Pacific Railroad at Grand Avenue, east of I-294) under the Elgin O'Hare Western Access project. The original contract was solicited under PSB 21-3 and approved by the Tollway Board on April 26, 2020, for $3.122 million. A first supplement of $1.5 million was approved December 10, 2024.

The additional $995,000 funding is attributed to construction delays from utility relocations, Union Pacific Railroad flagger requirements, and unforeseen conditions that have extended the project timeline. The work is deemed germane to the original scope and remains within project limits. Construction is anticipated to continue through summer 2027, with final closeout expected by the end of 2027. The change order notice is being posted to satisfy the 14-day public notice requirement triggered by the modification amount exceeding $25,000 and the timeline extension of 180 days or more.
