There are many factors that go into deciding which tunnel construction method to use, such as the ground and groundwater 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 the shape of the tunnel. Tunnel construction is a subset of underground construction, so the selection of the right equipment is crucial.
