CHANGE ORDER NOTICE I-17-4326 Owner's Tollway Rep, Constr. Corridor Mgmt. , & Constr. Mgmt. Svc.

This contract opportunity is for a change order to supplement an existing contract (I-17-4326) that provides Corridor Construction Management (CCM) and Construction Management (CM) services for the Central Tri-State (CTS) corridor in Cook County, Illinois. The original contract, valued at $157,000,000.00, was approved by the Illinois State Toll Highway Authority Board in November 2017 and awarded to TranSystems Corp. dba TranSystems Omega LLC. This change order will provide an additional $13,300,000.00 in CCM and CM services under the existing contract. The change is necessary due to an increase in the number of construction contracts from 56 to 86, with peak construction now anticipated to occur in 2025 and extend into 2027, rather than peaking in 2021 as originally planned. The additional services are considered germane to the original contract as the work is within the project limits and necessary to complete construction of the corridor as intended.

The change order is being issued in accordance with Illinois procurement regulations, which require notice of contract renegotiations and change orders that increase the cost by more than $10,000 or the time of completion by 30 days or more. The change order details the rationale for the modification and certifies that the circumstances necessitating the change were not reasonably foreseeable at the time the original contract was signed. There are no set-aside designations or restrictions on the types of organizations that can respond, as this is an addendum to an existing contract. The incumbent vendor, TranSystems Corp. dba TranSystems Omega LLC, will continue to provide the additional services.
