Summary: The Department of Transportation and Highways respectfully requests the approval of the proposed Contract Amendment between the County and R.W. Dunteman Company, Addison, Illinois. On June 24, 2021, 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.
This amendment accounts for changes required from unexpected field conditions, design changes, and to coordinate with the Illinois Tollway’s I-294 widening project that is adjacent to the County Line Road project and recently completed. The Illinois Tollway project has been prioritized resulting in changes to planned staging of work and traffic control than originally anticipated when both projects were designed. The Illinois Tollway has requested that some of the work on the project be accelerated to reduce delays caused by unexpected field conditions, design changes, and the prioritization of the I-294 widening project. Design changes incorporated into the amendment accounts for additional maintenance of traffic and applicable temporary pavement, storm sewer revisions, additional maintenance to guardrail and an additional traffic signal, and extensive revisions to the WB Lake Street Bridge. Finally, the amendment accounts for work that was not included in the project but was required to meet the goals of the project including additional pavement work and pavement striping. All changes are germane to the contract and required to complete the roadway, bridge, drainage, and traffic improvements safely and effectively.
This contract was awarded pursuant to a publicly advertised Invitation for Bid (IFB) in accordance with the Cook County Procurement Code. R.W. Dunteman Company was the lowest, responsive, and responsible bidder.
