Description
The previous tender for the current LSTOC system was via an OJEU Competitive Dialogue procedure under the Procurement Regulations 2005. The contract was awarded on 12th August 2014 and the Contract commenced May 2016 once the system went live for a period of 10 years. The LSTOC is vital to enable TfL to perform its authority duties and obligations, particularly regarding the safety and operability of 13 existing road tunnels on the Transport for London Road Network. The LSTOC will continue to monitor and control tunnel safety systems in the tunnels and the associated London Traffic Control Systems (LTRACS) on approximately 90km of approach roads. The LSTOC is mission-critical to the safety and continuous operation of the tunnel infrastructure within the TfL network TfL are extending the existing contract with Indra for a period of 3 years to allow sufficient time for a comprehensive re-procurement exercise to be undertaken using the Competitive Flexible Procurement route to market under PA23, and to allow the new supplier time to build, implement and transition to the new system.

Legal Justification
This contract extension is necessary due to: The mission critical nature of the system being procured The need to accommodate a re-procurement project during the term of the contract and allow a period of transition/dual running which is expected to be between 7-36 months between Indra & the awarded supplier IPR Ownership: Indra owns the intellectual property rights (IPR) for the LSTOC, any other supplier would need a license to access and maintain the system. Procuring a license from Indra for a third-party supplier would create additional cost for TfL, which is considered an economic inconvenience. Beyond cost, introducing a new supplier without full system knowledge could pose technical risks to a mission-critical system, reinforcing the justification. The supplier provides a critical service that cannot be interrupted without creating significant operational risk. Transitioning to a new supplier before the current contract expires would cause delays and service disruptions, as the incoming supplier would require sufficient time to design, implement, and transition to a new system. From a commercial perspective, there is not enough time for a new supplier to build and maintain a replacement system prior to the expiry of the existing contract. Maintaining the current supplier ensures continuity of service and mitigates operational and safety risks. The procurement exercise is estimated to take place April 2026.
Other Information
Extension of the existing contract to ensure continuity of critical services. The LSTOC is classified as a 'mission critical' system under the Security of Networks & Information Systems (NIS) Regulations and supports essential operational safety.
