Facts and Figures
Comparison between buildings
Burj Khalifa, earlier known as Burj Dubai, located in Downtown Dubai UAE.
Burj Khalifa is tallest man made structure in the world.
Burj Khalifa developed by the leading developer Emaar Properties
Construction of the project began on 21st September 2004 and the building officially opened on 4 January 2010
Burj Khalifa is as a living wonder, a stunning piece of art, and incomparable feat of engineering.
Burj Dubai was officially renamed by Dubai’s ruler as the Burj Khalifa named after the UAE president Sheikh Khalifa Bin Zayed.
The primary design concept of the tower is an organic form with tri-axial geometry and spiraling growth that can be easily seen in the final design
The floor plan of the tower consists of a tri-axial, “Y” shaped plan, formed by having three separate wings connected to a central core
Over 45,000 m3 of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation
Burj Khalifa's construction will have used 330,000 m3 of concrete and 39,000 tonnes of steel rebar, and construction will have taken 22 million man-hours
The amount of rebar used for the tower is 31,400 metric tons - laid end to end this would extend over a quarter of the way around the world.
The architecture features a triple-lobed footprint, an abstraction of the Hymenocallis flower
The tower is composed of three elements arranged around a central core
The modular, Y-shaped structure, with setbacks along each of its three wings provides an inherently stable configuration for the structure and provides good floor plates for residential
The central core emerges at the top and culminates in a sculpted spire
The project scope is the definition of what the project is supposed to accomplish and the budget of both time and money that has been created to achieve these objectives.”
The initial planned costs of the Burj Khalifa project was $876 million dollars
The initial planned height was 728 meters from the ground
The engineers of the tower worked the design of the structure to avoid the two major challenges; wind and gravity.
Samsung engineering and Besix, introduced new technologies based on previous experiences with tall building construction.
Following technologies were used for building Burj Khalifa :
The net profit increased 10 times compared to 2009
Antenna spire : 829.84 m (2,723 ft)
Roof : 828 m (2,717 ft)
Top floor : 621.3 m (2,038 ft)
