    Cut-and-cover is a simple method of construction for shallow tunnels where a trench is excavated and roofed over with an overhead support system strong enough to carry the load of what is to be built above the tunnel. Two basic forms of cut-and-cover tunnelling are available: Bottom-up method: A trench is excavated, with ground support as necessary, and the tunnel is constructed in it.
