|Original Reference #22015968 Change Order T-022 Construct Maintenance Crossover: During the design phase, the DSE recommended the Tollway consider maintaining the existing crossovers or turnarounds used for maintenance and emergency responders by leaving an opening in the median barrier. The Tollway did not feel that these opening were required due to the proximity of the interchanges, and therefore the contract did not provide for the openings in the median barrier. After award of the contract, Tollway Maintenance requested these openings be added to the contract. If approved, this work shall compensate the contractor for the time, material, and equipment required to perform this work in accordance with subsections 109.3 and 109.4 of the ISTHA Standard Specifications.|
The CM has estimated a unit cost for impact attenuators based upon similar work using similar materials in the region. This work will be tracked on A-7’s and paid for in accordance with subsection 109.4 of the Standard Specifications, should the contractor’s AUP be considered unacceptable. A portion of the added cost will be reduced by a reduction of Item Concrete Barrier, Double Face, 42” which is no longer required due to this change.
