encounters a different building shape.
This structural system enables the building to support itself
laterally and keeps it from twisting.
At the top, the central core emerges and transitions to
a special steel framed structure which is sculpted to form a
finished spire. The spire of Burj Khalifa is composed of more
than 4,000 tons of structural steel.
The building utilizes high-speed, non-stop shuttle
elevators to sky lobby floors where passengers transfer to
local elevators serving the floors in between.
Burj Khalifa has 57 elevators
and 8 escalators. Travelling
at 10 meters/sec (33 feet/
sec) per second, they have
the world’s longest travel
distance from lowest to
highest stop. The building
service/fireman’s elevator
will have a capacity of 5,500
kilograms (12,000 pounds)
and is the world’s tallest
service elevator.
To achieve the greatest
efficiencies, the mechanical,
electrical and plumbing
services for Burj Khalifa
were developed all together
during the design phase of
the tower in cooperation with
the architect, structural
