Tunnel Inspection, Rehabilitation, Operation

Expected to provide safe and secure transportation links, tunnels represent significant public infrastructure investments for the communities they serve. As such, they need to be maintained through regular inspections, rehabilitated as needed, and operated in a safe manner.

Drawing on our international and local experience, WSP is skilled in carrying out inspections and condition assessments of all types of tunnels, and providing innovative rehabilitation solutions. This includes reconditioning of inner shells, drainage, safety-related retrofits and waterproofing remediation to extend the life of tunnels.

We also design upgrades to meet fire protection and safety standards including state-of-the-art energy-efficient ventilation and lighting systems. And, we undertake operational evaluations and lifecycle costings to ensure tunnels achieve optimum efficiency, higher performance and greater returns on investment for our clients.
