Burj Khalifa

Completed in 2012, the Burj Khalifa is the tallest building in the world standing at 2,712 feet. It uses a double reinforced concrete system in its primary structure. The concrete material uses fiberglass reinforcement, which was pumped to the upper sections of the building. According to building engineers, the reinforced concrete is the reason the Burj Khalifa could reach nearly 3,000 feet.
