To celebrate Bechtel’s involvement in the First LEGO League, they have commissioned UK LEGO Certified Professional Bright Bricks to create a replica of a tunnel boring machine. The 2-meter long model consists of 50,000 bricks and was created with the help of Bechtel’s engineers. The miniature model shows all the working components of a real tunnel boring machine. It is of 1/20 scale and took a 3-man team 25 days to finish. Check out the video below:
