LEGO Tunnel Boring Machine

Bechtel has built a moving replica of a tunnel boring machine from 50,000 LEGO bricks. The two-meter long model shows all the components of a working tunnel boring machine and demonstrates how these mechanical moles dig and build tunnels all over the world. The model was created to celebrate Bechtel's involvement with FIRST LEGO League, an international robotics tournament for students aged nine to 16 years. The competition teaches children to think like scientists and engineers by building autonomous robots and create innovative solutions to real-world problems.
Bechtel hopes that the machine will inspire young people to pursue careers in engineering.
