Can It Be Built? Episode Rating Graph

Abu Dhabi will set out on the biggest project to date – a new micro-city with a round skyscraper taller than the Statue of Liberty and curved glass skin covering the area of four football fields. The spherical design and the proposed site pose numerous challenges, including design stability and a location that is half a mile out in the Persian Gulf and 25 feet under water. On top of everything, this skyscraper must be completed in just 30 months’ time.

Abu Dhabi is famous for its extreme engineering, but now one project could surpass them all – the world’s most inclined skyscraper, Capital Gate. Capital Gate is a tower that spirals out of the ground at 525 feet and tilts almost five times more than the Leaning Tower of Pisa. The tower will include a five-star hotel on the top 18 levels, an infinity pool, a restaurant hanging 300 feet above the ground and a helicopter pad on the roof.

The world's tallest building, the Burj Khalifa in Dubai, cost $1.5 billion and took seven years to build.
