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

The Illinois State Toll Highway Authority has issued a change order notice, not a solicitation, adding $995,000 to Contract I-21-4744 with STV Inc. for Phase III construction management on the Elgin O'Hare Western Access project, with a listed due date of November 16, 2026. The notice is the second supplement to the contract and is posted on BidBuy for the 14-day period required for changes exceeding $25,000 or extending completion by 180 days or more.

The supplement covers the Railroad Bridge Construction over Grand Avenue east of I-294 and requires STV to continue on-site inspection, layout review, design change evaluation, geotechnical inspection and testing, records and documentation, pay estimate preparation, change order processing, and project closeout under Tollway specifications. The authority attributes the amendment to utility relocations, Union Pacific Railroad flagger requirements, and unforeseen conditions. Construction is now anticipated to run through summer 2027, with closeout expected by the end of 2027.

The original contract was approved April 26, 2020 under Board Resolution 22440 at $3.122 million. A first supplement approved December 10, 2024 added $1.5 million, and this second supplement brings total authorization to $5.617 million.
