Summary: The Department of Transportation and Highways respectfully requests approval of the proposed Contract Amendment No. 1 between Cook County and R.W. Dunteman Company, Addison, Illinois.
This Contract was approved by the board on March 17, 2022, for County Line Road improvements located within the Cook County Board District 17 in accordance with the plans and specifications. 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 caused significant changes to the maintenance of traffic needed by the acceleration of work requested by the Illinois Tollway.
The amendment accounts for differing field conditions including removing thicker existing pavement than anticipated, repairs to various impact attenuators, additional structure excavation, temporary soil retention system, earth excavation, removal and disposal of non-special waste, and modifications to work on adjacent property owners’ driveways at their request. Finally, the amendment accounts for work that was not included in the project but required to meet the goals of the project including additional tree removal, trench backfill, and concrete structures.
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.
