Summary: The Department of Transportation and Highways respectfully requests approval of the proposed Amendment between Cook County and R.W. Dunteman Company, Addison, Illinois.
This Contract was approved by the board on June 24, 2021, for County Line Road improvements located within the Cook County Board District 17 in accordance with the plans and specifications. This amendment provides for the changes associated with the estimated and actual quantities performed on site.
This is a contract amendment for the County Line Road from I-294 Ramp to North Avenue project with the R.W. Dunteman company. The amendment accounts for changes required from unexpected field conditions and to coordinate with the Illinois Tollway’s I-294 widening project that is adjacent to the County Line Road project and is running concurrently. 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 and the prioritization of the I-294 widening project. In addition, 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.
This contract was awarded 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.
