Summary: The Department of Transportation and Highways respectfully requests approval of the proposed Amendment between Cook County and R. W. Dunteman Company, Addison, Illinois.
On March 17, 2022, your honorable Body awarded a contract to R. W. Dunteman Company, Addison, Illinois for the aforesaid improvement to be completed in accordance with the plans and specifications.
The quantities as shown on the contract documents were estimated for bidding purposes only. This change represents the difference between the estimated quantities and actual field quantities of work performed. The amendment accounts for changes required to coordinate with the Illinois Tollway’s I-294 widening project that is adjacent to this County Line Road project and is running concurrently. The Illinois Tollway project has created differing field conditions than originally anticipated when both projects were designed. The coordination of the two projects and resulting field conditions have resulted in significant changes to the sequence of work. The amendment accounts for maintenance of traffic work needed by the accelerated work performed per the Illinois Tollway’s request within the project. This includes additional winter protection of concrete pavement, modifications of traffic safety devices, and pothole patching that was needed for the roadway. Additional work included storm sewer modification.
This contract was selected pursuant to a publicly advertised Invitation for Bids (IFB) in accordance with the Cook County Procurement Code. R. W. Dunteman Company was the lowest, responsive and responsible bidder.
