    Brief

    National Highways is seeking an independent design checker to provide Category 3 checking services for the new Tunnel Control and Management System (TCMS) being deployed at Hindhead Tunnel. This role involves reviewing design and test documents to ensure compliance with CG300 technical approval standards and CD352 design requirements for road tunnels. The TCMS is in the final stages of implementation and requires design certification before completing the fault-free running period, trial period, and safety case. Additionally, National Highways requires Approval in Principle (AiP) assessments for Southwick and Roundhill Tunnels to support planned refurbishment schemes. The successful supplier will have expertise in tunnel systems design verification, standards compliance, and the ability to work with complex control and management systems. This is an opportunity to support critical national infrastructure safety and compliance.
