## Summary

Network Rail Infrastructure Limited procured engineering services for Phase 2 of the Trapped Key Remote Securing project. The work concerns the detailed design and development of a Remote Securing Controller, which will allow disconnectors forming Points of Isolation to be secured remotely. The intended safety benefit is to remove the need for operational staff to travel to sites to apply padlocks, while improving operational efficiency. The scope covers detailed SCADA design, Remote Securing Controller software development, software testing, factory acceptance testing and cyber security. The requirement is associated with Network Rail’s Wales & Western Remote Securing Programme. The procurement is categorised as mechanical and electrical engineering services, under CPV 71334000.

The procurement has been awarded through a direct award and is complete. Navitas Engineering Limited was selected for the single lot. The award is valued at £1,605,801.02 excluding VAT, or £1,926,961.23 including VAT. The contract period runs from 21 September 2026 to 31 July 2027. Network Rail justified the direct award on intellectual property and technical grounds: the software must integrate with an existing SCADA system whose intellectual property Network Rail does not own, and Navitas is already developing the required interfaces. The supplier’s existing role and continuity from the previous phase were also cited as necessary to avoid compatibility problems, disproportionate cost, technical risk and programme impact. The procurement is subject to the utilities regime.

This requirement is most relevant to engineering and technology suppliers able to combine railway electrical safety knowledge with control-system software delivery. Credible competitors would need experience designing and integrating SCADA interfaces, developing embedded or controller software, and testing safety-related systems through factory acceptance testing. Cyber security capability is also central, alongside the ability to understand system architecture, stakeholder requirements and existing infrastructure rather than deliver a stand-alone product. The award rationale shows that continuity, technical compatibility and ownership or access to relevant intellectual property were decisive. Suppliers seeking comparable work from Network Rail should therefore be able to demonstrate end-to-end engineering capability, established knowledge of railway isolation arrangements, and the capacity to work within an existing programme and software environment.

## Notice

Remote Securing is part of the Electrical Safety Delivery programme, developing solutions for remotely securing disconnectors that form Points of Isolation (PoIs). Securing Points of Isolation is a requirement of the Electricity at Work Regulations 1989, and solutions for applying securing measures remotely will eliminate the need for operational staff to travel to sites to apply padlocks, leading to safety and efficiency benefits. This is for Phase 2 of the Remote Securing Controller (RSC) design of the Trapped Key Remote Securing project, including Detailed Design of the SCADA scope, Software Build and Factory Acceptance Testing. Deliverables for this contract include: Detailed Design for SCADA, RSC Software Development, Testing and Cyber Security.

### Procurement Information

The direct award to Navitas Engineering is justified due to its existing role in the Wales & Western Remote Securing Programme and its extensive knowledge of the developing solution, associated infrastructure, and project requirements. The software development element is dependent upon integration with the existing SCADA software system, for which Network Rail does not own the intellectual property rights. The required interfaces with this system are already being developed and delivered by Navitas Engineering as part of the current Remote Securing design. Furthermore, this contract represents a continuation of the previous phase of services delivered by the Navitas Engineering. Appointing an alternative supplier at this stage would create significant technical compatibility issues and result in disproportionate cost, risk, and programme impacts, making Navitas Engineering the only viable supplier to deliver the required services efficiently and effectively. Under Schedule 5 - Direct Award Justifications of the Procurement Act 2023, which outlines conditions for direct awards: Section 5 states: "The following conditions are met in relation to the public contract-- (a) due to a particular supplier having intellectual property rights or other exclusive rights, only that supplier can supply the goods, services, or works required; and (b) there are no reasonable alternatives to those goods, services, or works." The direct award to Navitas Engineering is in accordance with Schedule 5 of the Procurement Act 2023 UK, on the basis that the services can be supplied only by this supplier due to technical reasons and the need for continuity and compatibility with existing works. Navitas Engineering has been integral to the development of the W&W Remote Securing design to date and holds detailed knowledge of the existing PACE 1 outputs, system architecture, and stakeholder requirements.
