Question: what is the biggest machine you worked with?

I have recently been working with Thames Tideway who are building a new ‘super sewer’ to help remove all of London’s waste without if spilling into the river… they have huge tunnel boring machines that will cut the new tunnels through the rock underneath London. I also worked on a project last year that used the world’s largest crane to lift huge concrete supports out of the ground, it took several weeks to arrive from America and be rigged before use.
