One of the biggest engineering projects in the world is currently going on, almost without being noticed, underneath the streets of London. The Crossrail project is £15,000,000,000 worth of tunnels being dug to allow people to take trains across London without having to change stations via the Tube network. The statistics that go with the tunnel are staggering and can be seen by clicking the link below.
BBC News story
Tunnelling presents a huge range of engineering and geological challenges and does provide some very good job opportunities for engineering geologists, if you can cope with the unusual working environment. Matt Lock, a former Cowbridge student, is working on this project as a geotechnical engineer. What do you think the challenges of tunnelling through different rock types? How could these problems be solved?
