World Records
At over 828 mts and more than 160 stories,
Burj Khalifa holds the following records:
• Tallest building in the world
• Tallest free-standing structure in the world
• Highest number of stories in the world
• Highest occupied floor in the world
• Highest outdoor observation deck in the
world
• Elevator with the longest travel distance in
the world
• Tallest service elevator in the world
Purpose
• Burj Khalifa has been designed to be the centerpiece
of a large-scale, mixed-use development
• That will include 30,000homes, 9hotels ,3 hectares
of parkland, at least 19residential towers, the Dubai
Mall, and the 12-hectare man-made Burj Khalifa Lake
• The decision to build Burj Khalifa is reportedly based
on the government's decision to diversify from an oilbased economy to one that is service-and tourismoriented
• According to officials, it is necessary for projects like
Burj Khalifa to be built in the city to grab more
international recognition
Architecture
• The design of Burj Khalifa is derived from patterning
system embodied in Islamic architecture
• Burj Khalifa is expected to hold up to 35,000 people
at any one time
• A total of 57 elevators and 8 escalators are installed.
The elevators have a capacity of 12 to 14people per
cabin, the fastest rising and descending at up to 18
m/s(59 ft/s).Elevators Speed = 35 km/h & biggest
one can get 46 passengers at a time.
• The Burj Khalifa's water system supplies an average
of 946,000 litters of water per day. Burj Khalifa used
30000 tons steel and 30000 Glasses and having
weight of half a million tons.
Foundation
• The superstructure is supported by a large reinforced
concrete mat, which is in turn supported by bored
reinforced concrete piles.
• The design was based on extensive geotechnical and
seismic studies.
• The mat is 3.7 meters thick, and was constructed in
four separate pours totaling 12,500 cubic meters of
concrete.
Foundation
• The 1.5 meter diameter x 43 meter long piles
represent the largest and longest piles
conventionally available in the region.
• A high density, low permeability concrete was
used in the foundations, as well as a cathodic
protection system under the mat, to minimize
any detrimental effects form corrosive
chemicals in local ground water
Structural System
• In addition to its aesthetic and functional
advantages, the spiraling “Y” shaped plan was
utilized to shape the structural core of Burj Khalifa.
• This design helps to reduce the wind forces on the
tower, as well as to keep the structure simple and
foster constructability.
• The structural consists of high performance concrete
wall. Each of the wings buttress the others via a sixsided central core, or hexagonal hub.
• Central core provides the torsional resistance of the
structure, similar to a closed pipe or axle.
Corridor
• Corridor walls extend from the central core to
near the end of each wing, terminating in
thickened hammer head walls.
• These corridor walls and hammerhead walls
behave similar to the webs and flanges of a
beam to resist the wind shears and moments.
• Perimeter columns and flat plate floor
construction complete the system.
• At mechanical floors, outrigger walls are
provided to link the perimeter columns to the
interior wall system, allowing the perimeter
columns to participate in the lateral load
resistance of the structure;
Corridor
• hence, all of the vertical concrete is
utilized to support both gravity and
lateral loads. The result is a tower that
is extremely stiff laterally and torsion
ally.
• It is also a very efficient structure in
that the gravity load resisting system
has been utilized so as to maximize its
use in resisting lateral loads.
Floor Plan
• Concourse level to level 8 and level 38 and 39 will
feature the Armani Hotel Dubai. Levels 9 to 16 will
exclusively house luxurious one and two bedroom
Armani Residences.
• Floors 45 through 108 are private ultra-luxury
residences. The corporate suites occupy fill most of
the remaining floors, except for level 122 which
houses a restaurant and level 124, the tower‘s public
observatory.
• For the convenience of home owners, the tower has
been divided in to sections with exclusive Sky Lobbies
on Levels 43, 76 and 123 that feature state-of-the-art
fitness facilities including a Jacuzzis on Level 43 and 76.
• The Sky Lobbies on 43 and 76 additionally house
swimming pools and a recreational room each that can
be utilized for gatherings and lifestyle events.
• Offering an unparalleled experience, both pools open
to the outside offering residents the option of
swimming from inside to the outside balcony.
• Other facilities for residents include a Residents'
Library, and Burj Khalifa Gourmet Market, a gourmet
convenience store and meeting place for the residents.
Valet parking will be provided for guests and visitors.
Exterior Cladding
The exterior cladding is comprised of reflective glazing
with aluminum and textured stainless steel spandrel
panels and stainless steel vertical tubular fins. Close to
26,000 glass panels, each individually hand-cut, were
used in the exterior cladding of Burj Khalifa. Over 300
cladding specialists from China were brought in for the
cladding work on the tower. The cladding system is
designed to withstand Dubai's extreme summer heat,
and to further ensure its integrity, a World War II airplane
engine was used for dynamic wind and water testing. The
curtain wall of Burj Khalifa is equivalent to 17 football
(soccer) fields or 25 American football fields.
