The Great Pyramid of Giza was the tallest building in the world for more than 3,800 years.

The Hoover Dam is constructed from 3,250,000 cubic yards of concrete. This is enough material to build a two-and highway between San Fransisco and New York City, covering almost 3,000 miles.

During peak construction periods, there were more than 12,000 people working on the Burj Khalifa every day. The building is the tallest man-made thing the world.
