Burj Khalifa — The World's Tallest Tower
Burj Khalifa lifts the world's head proudly skywards, surpassing limits and expectations. Rising gracefully from the desert and honouring Dubai with a new glow. Burj Khalifa is at the heart of Dubai and its people; the centre for the world's finest shopping, dining and entertainment and home for the world's elite. Burj Khalifa's Grand Vision

World's tallest building. A living wonder. Stunning work of art. Incomparable feat of engineering. Burj Khalifa is all that. In concept and execution, Burj Khalifa has no peer. More than just the world's tallest building, Burj Khalifa is an unprecedented example of international cooperation, symbolic beacon of progress, and an emblem of the new, dynamic and prosperous Middle East. It is also tangible proof of Dubai's growing role in a changing world. In fewer than 30 years, this city has transformed itself from a regional centre to a global one. This success was not based on oil reserves, but on reserves of human talent, ingenuity and initiative. Burj Khalifa embodies that vision. Mr Mohamed Alabbar, Chairman, Emaar Properties, said: "Burj Khalifa goes beyond its imposing physical specifications. In Burj Khalifa, we see the triumph of Dubai's vision of attaining the seemingly impossible and setting new benchmarks. It is a source of inspiration for every one of us in Emaar. The project is a declaration of the emirate's capabilities and of the resolve of its leaders and people to work hand in hand on truly awe-inspiring projects. Emaar had but one inspiration, the unflagging enthusiasm set in motion by His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, who inspires us to reach for the stars. Building a Global Icon

Excavation work began for Burj Khalifa in January 2004 and over the ensuing years to its completion, the building passed many important milestones on its goal to become the tallest man-made structure the world has ever seen.

Construction Highlights
Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation, which features 192 piles buried more than 50 m (164 ft) deep.
