The Illinois Tollway is seeking a vendor to provide authorized Navistar Original Equipment Manufacturer (OEM) Truck Repair Services. The Tollway currently operates approximately 310 medium- and heavy-duty Navistar trucks. The Illinois Tollway performs the majority of the repairs to these trucks in-house and will continue to process them in-house when feasible. This contract shall provide ancillary sources for Navistar truck repairs that, for various reasons, the Tollway is unable to perform directly. The types of repairs under this contract will be those that the Tollway’s experienced technicians cannot perform due to workload, uniqueness of the repair, or if Navistar warranty participation is expected. Since this contract is reactive to unexpected repairs, it is not possible to determine the number of repairs that will be performed by the Vendor(s) annually. A reasonable estimate for the total number of repairs is 30 per year.
