The average cost per metre of a bored tunnel will be influenced by a number of factors. This includes the ground and soil conditions, the sequencing of a project, the drive length, the depth of the tunnel and production rates.

On the Crossrail project the cost per metre of the twin bored tunnels is between £30 – 35,000 at a base date of Q3 2013. This figure excludes additional scope within the tunnelling contracts including the construction of tunnel portals, shafts, tunnel cross passages, tunnel fit out, design, project management and spoil disposal.
