Kingsway Tunnel Refurbishment (Dado Panels)

Description

The contracting authority intends to procure a suitably qualified contractor to undertake refurbishment and/or replacement works to the dado panel system within the Kingsway Tunnel. The Kingsway Tunnel is a critical piece of transport infrastructure, and the existing dado panels-forming part of the tunnel lining and safety system-require upgrade to ensure continued compliance with current safety standards, durability requirements, and operational performance. The appointed contractor will be responsible for delivering a comprehensive programme of works, which is expected to include, but not be limited to: Condition Assessment and Surveys: Detailed inspection of existing dado panels, fixings, and supporting structures to determine extent of deterioration, defects, and required interventions. Design Development: Finalisation of design solutions for refurbishment and/or replacement, including materials selection, fire resistance, impact resistance, and compliance with relevant UK and EU tunnel safety standards. Removal and Installation Works: Safe removal of existing panels where required and installation of new or refurbished dado panels, including all associated fixings, supports, and interfaces with tunnel systems. Integration with Tunnel Systems: Coordination with existing tunnel infrastructure, including drainage, ventilation, lighting, and emergency systems, ensuring no adverse impact on operations or safety. Traffic and Operational Management: Planning and implementation of works to minimise disruption, including phased delivery, night-time or partial closures, and coordination with tunnel operations. Health, Safety, and Compliance: Adherence to all relevant health and safety legislation, including working in confined spaces and live highway environments, with robust risk management procedures. Environmental Considerations: Management of waste, materials, and environmental impacts in line with applicable regulations and sustainability objectives. Testing, Commissioning, and Handover: Inspection and verification of installed systems, ensuring compliance with specifications and provision of as-built documentation. The works will be delivered in a highly constrained operational environment, requiring careful planning, stakeholder coordination, and experience in similar tunnel or highway infrastructure projects. This procurement seeks to appoint a contractor with proven expertise in tunnel refurbishment, highway infrastructure works, and installation of specialist panel systems. The project outputs will contribute to the long-term safety, resilience, and operational efficiency of the Kingsway Tunnel.
