A new class of super structures are taking on the impossible: the largest moveable building in history, a super-tall skyscraper built to withstand killer earthquakes, and a bridge being raised while it stays open to traffic.

Around the world, engineers are fighting back against a new class of superstorm, raising some of the biggest sea defences in the world. This episode: the Venice flood barrier, Tokyo's underground water diversion tunnels, and New Jersey storm defense.

Across the world, engineers are going to extreme lengths to keep the lights on: harnessing the power of the longest river on Earth, tapping into the raging heat of a live volcano, and building one of the largest offshore wind facilities in the world.

A new breed of tools allows man to face deadly forces once thought impossible. On this episode: a polar survival suit, a thermal imaging fire fighter mask, and a big wave surfing emergency vest.

Toppling giants of concrete and steel is dangerous and deadly. In demolition, one mistake can cost you your life. On this episode: imploding a casino, dismantling chemical weapons and tripping a silo.

America has a history of building the impossible. Across the nation, a new generation of impressive projects is underway. On this episode: New Tappan Zee Bridge, Los Angeles Subway, New Orleans pump station, and Mount Rushmore preservation.

Brand new machines are helping explorers reveal mysteries once thought lost forever; underwater archaeologists search for a World War II Nazi sub, whilst in Scotland, researchers are digging up an ancient rock covered with cryptic markings.

New technology is allowing us to build underground structures that far surpass any building on earth: South Dakota builds a mile deep structure to study the universe, whilst Mexico City burrows 39 miles underneath the city to save it from drowning.

Above the arctic circle, projects are underway that are opening up the Arctic to the rest of the world. On this episode: building a nuclear-powered icebreaker in Russia; and constructing a modern airport on Baffin Island.

A revolution in engineering is making today's technology as outdated as the horse and buggy. On this episode: Lightning LS-218, the world's fastest production motorcycle; and Hyperloop, a train faster than the speed of sound
