Building Giants - Season 2

Engineers brave the extreme cold and endless nights in the Arctic Circle of northern Sweden to build one of the largest ice hotels in the world, and using cutting-edge tech, they'll move 15,000 tons of snow and ice to construct this modern marvel in just six weeks.

When an elite team of engineers race to build a record-breaking roller coaster in just sixteen months, they use brand-new technology and the latest construction methods to turn 1,500 tons of steel into the fastest and tallest dive roller coaster in the world. This is the Yukon Striker at Canada's Wonderland near Toronto, Canada.

A team of expert engineers must complete the brand-new Samuel-de-Champlain Bridge in just three months, and using cutting-edge tech and the latest construction methods, this innovative megastructure has been build to brave the deadly winter weather of the Great North. It's a twin cable-stayed bridge two miles long over the Saint Lawrence River in Montreal, Quebec, Canada.

The Las Vegas High Roller is the world's tallest Ferris Wheel, and expert engineers use cutting-edge tech and the latest construction methods to build this 550-foot marvel, one of the great wonders of Nevada's Sin City.

One of the world's fastest trains, the Italo AGV, races between Milan and Rome at nearly 200 miles per hour, and expert engineers use cutting-edge tech and the latest construction methods to build and operate what is known as the Ferrari of Trains.

As engineers race to build a brand-new train tunnel beneath the Alps, they use cutting-edge tech and the latest construction methods to build the world's longest underground railroad in some of the most dangerous conditions on earth. The Brenner Base Tunnel will be 34 miles long through the base of the Eastern Alps beneath the Brenner Pass. It will run from near Innsbruck, Austria to Fortezza, Italy.

The Antonov 124 is one of the biggest airplanes in the world, and as its cutting-edge engineering and immense size help it carry impossibly heavy cargo, the plane's crew races the clock to make critical international deliveries on schedule.

New York's Central Park Tower is the second tallest building in the United States and the tallest residential tower in the world. As engineers and builders race to complete this 1,550-foot-tall mega build, they use cutting-edge science and engineering to battle high altitudes and brutal weather.
