ABOUT THIS PROGRAMME
1/4. "The might of the biggest, most awe-inspiring and technologically advanced drilling, excavation and tunnelling equipment known to man, as it takes on some of the world's most challenging engineering projects. Programme one features diggers burrowing below the world's cities - a massive boring machine facing the challenge of excavating Britain's deepest-ever tunnel in London and a giant mechanical worm making the earth move just metres beneath Mexico's soaring skyscraper."
