Transportation tunnels are often necessarily built in the densest urban centres to help relieve the very density that complicates their construction. WSP employs experts across all aspects of tunnelling practices to ensure that we have the expertise on hand to confront even the most complex or intensive projects.
Tunnels are dug in types of materials varying from soft clay to hard rock. The method of tunnel construction depends on such factors as the ground conditions, the ground water conditions, the length and diameter of the tunnel drive, the depth of the tunnel, the logistics of supporting the tunnel excavation, the final use and shape of the tunnel and appropriate risk management.
