Change Order: TDX System Maintenance - Change Order No. 3 TDX Unidirectional Gateway Network Security Solution (Modern Communications Systems)
end
AGENDA ITEM TYPE:
Procurement Contract/Change Order
RECOMMENDATION:
Approve and authorize execution of Change Order No. 3 and associated disbursements for the TDX 3.0 Upgrade Contract with Modern Communications Systems (MCS) for a value of $348,369 to modernize UTA’s Operations Network.
BACKGROUND:
UTA has an existing contact with Modern Communications System to upgrade TDX to version 3.0 on both TRAX and Frontrunner. This contract was awarded to MCS in December of 2019. This contract is for three years and includes work on both the TRAX Light Rail system and the FrontRunner commuter Rail system.
DISCUSSION:
UTA Staff is requesting approval of Change Order #003 with MCS. To modernize the UTA Operations Technology (OT) Network and to gain benefits from the TDX 3.0 upgrade, UTA requires a secure way to access the OT Network (via the UTA Business Network) to create reports, generate automatic emails, and implement safety improvements. The OT network is currently secured using an air-gap method, which completely isolates the OT Network from the business Network. To maintain the air-gap equivalent security on the OT network, UTA needs to implement a system that allows information to only pass in one direction via a unidirectional gateway. This will ensure the security of the OT network and maintains an air-gap equivalency. This unidirectional gateway will also allow reports and emails to be sent from the OT network for trouble shooting and safety purposes. UTA Systems Engineering and IT departments have jointly agreed to use a system with a unidirectional gateway between the two networks. This security solution will be required on both the TRAX and FrontRunner systems.
The price of this Change Order No. 3, at a value of $348, 369, has been determined to be fair and reasonable based on evaluation of the itemized cost build-up and also an Independent Cost Estimate which came in at $380,050, or 19% higher. It is expected that the work included in this change order will be completed by December 31, 2021.
