CHANGE ORDER NOTICE Sole Source - Unisys Maintenance and Support

This is a Change Order Notice issued by the Illinois Chief Procurement Office for General Services on behalf of the Toll Highway Authority (THA) for Contract 23-0037, Unisys Maintenance and Support. The procurement involves Unisys Datacenter Move Services and related project management activities to support the migration of software infrastructure on VMware architecture. The scope of work includes deployment of software series using a logical "lift and shift" approach, which encompasses standing up new virtual machines, installing Windows operating systems and new CSS software, performing system outages to swap virtual machine disk files, installing new CSS versions, and managing cutover activities to reestablish iSCSI interface connectivity to the virtual tape library. Unisys personnel will collaborate with the THA's internal staff to deliver these services. The change order qualifies for posting as the circumstances necessitating this modification were not reasonably foreseeable at the time of original contract execution. The posting deadline for this change order is May 1, 2026, requiring a 14-day public notice period on the Bulletin/BidBuy, as the modification exceeds the $25,000 threshold.

This change order is being awarded to the incumbent vendor, Unisys, under sole source authority pursuant to Section 33E-9 of the Criminal Code, which permits modifications when circumstances were not reasonably foreseeable and the work remains germane to the original contract scope. No set-asides or restrictions on organizational types are applicable to this change order notice. The modification increases the upper dollar limit of Contract 23-0037 by $49,734.00, bringing the total contract value from $455,067.17 to $504,801.17. The current contract term remains unchanged with an expiration date of August 27, 2026. This change order does not represent a new competitive procurement opportunity, but rather a sole source modification to an existing contract with Unisys for critical datacenter infrastructure services.
