There are many methods of tunnel construction, each requiring specialist skills and equipment. These include techniques such as bored tunnels using Tunnel Boring Machines (TBMs), sprayed concrete lined tunnels, tunnels constructed by blasting with explosives, and tunnels constructed by pipejacking. This large variety means the tunnelling world and the skills it needs are constantly varied and challenging.

This video highlights the risks of tunnelling in poor ground conditions. This underscores the critical need for thorough ground investigations prior to construction stage and probing ahead of tunnel during the construction. The construction method should be adopted based on the geological conditions and risk and proactive ground stabilisation measures should be used where required. Tunnelling is essential for development, but its associated risks must be thoroughly understood, and mitigation mea
