CHANGE ORDER NOTICE I-19-4475 Widening over CSX and B OCT Railroad Bridge and I-57 Restriping

The Illinois Toll Highway Authority is issuing Change Order Notice I-19-4475 to amend the existing construction contract for I-57 widening over CSX and B&O railroad bridges and I-57 restriping, with a response or acknowledgment due October 14, 2026. This is a change order, not a new solicitation — the contract was awarded to Dunnet Bay Construction Co. on April 22, 2021, in the amount of $20.79 million and is currently set to expire October 28, 2026.

The change order requests a one-year amendment extension, with no additional funds required. The extension accommodates pending contractor claim review and processing. The contractor has submitted a claim under review by the Construction Manager, Project Manager, Deputy Project Manager, and Claim Administrator. If the claim merits approval, an Authorization to Proceed, Change Order, and/or Extra Work Order will follow, with payment through a pay estimate. Claim resolution and associated payment processing can require up to one year.

The project has experienced multiple delays throughout execution, including differing site conditions, utility delays, permit delays, right-of-way delays, coordination with an adjacent resurfacing construction contract, and an electrical maintenance transfer. The contract is nearly closed out except for the pending claim. The one-year extension provides sufficient time for full claim resolution and any resulting payments before final contract closure.
