The world’s tallest concrete building


The world’s tallest concrete building

At 2,716.5 feet with 160 storeys, the Burj Khalifa has several firsts to its credit. Besides being the tallest building in the world, it also holds the record as the tallest freestanding structure, the highest occupied floor, the world’s highest observation deck and the elevator with the longest travel distance. The Burj Khalifa’s elevators travel at a staggering 10 m/s but what’s even more intriguing is the tower is so tall, you can see the sunset twice in the same evening – once from the lower floors and then again at the top. In fact, the temperature at the top of Burj Khalifa is six degrees cooler than at ground level. Believe it or not, but the first 100 levels of Burj Khalifa were completed in 1,093 days – that’s 1 storey in 3 days! A dedicated concrete plant was installed on-site during construction and. over 45,000 m3 of concrete, weighing more than 110,000 tonnes, were used to construct its foundation alone.
