| Extreme Engineering unveils some of the most ambitious architectural plans of our times. Some are theoretical; others are in the works. But all of these modern marvels pose challenges that stretch the definition of what's possible. Watch as jaw-dropping computer animation and first-hand accounts from builders, designers and engineers breathe life into the most extreme construction projects ever conceived. At the world's largest open pit iron mine in northern Minnesota, workers are in desperate need of a new excavator – the monster shovel that serves as the workhorse of iron ore mining. Their old equipment is either too small or too worn out to meet the sudden worldwide surge in the demand for iron. And lost opportunity in the mining business translates into bankruptcy and massive layoffs when iron prices fall. That's why the company has gambled $10 million to commission a new, custom-built super shovel – the fastest, smartest, most technologically advanced excavator ever made. Watch as workers put this massive piece of machinery to the test to see if it can deliver the goods before the mine's window of opportunity closes. |
