How do we build in maintenance and service procedure for mecatiss after the protected tunnel is operational
What happens if after installation there are any gaps between the mecatiss boards What is the experience of such repairs in other protected tunnels Which is the best protection method that will minimise servicing requirements after the tunnel is completed - post cladding is easier to remove, while lost shuttering is more difficult
