    Brief

    National Highways seeks technical support services for the renewal of safety-critical systems in the A38 Saltash Tunnel. The current tunnel technology and systems are approaching end-of-life and require replacement to enhance resilience, efficiency, and safety operations. The successful contractor will provide comprehensive technical assistance including design verification (CAT3 level), testing, and installation oversight to ensure all work meets required standards and specifications. This engagement is necessary because the Principal Contractor and their subcontractors lack the specialized expertise and capacity to deliver these services in-house. The work is critical to programme delivery and addresses challenges encountered during project planning. Suitable candidates should have proven experience in tunnel systems renewal, safety-critical technology implementation, design verification, and installation management.
