Burj Khalifa Facts
“Burj Kahlifa” world’s tallest building.
Height : 829.8m (2,722 ft).
Occupied Floor area : 33,31,100 sq. ft.
Consists of 163 floors, plus 46 maintenance levels
and 2 parking levels in basement.
Situated in Dubai, United Arab Emirates.
Why it is Constructed ?
It is constructed to change Dubai’s economy from an oil
based to one that is service and tourism based.
Sheikh Mohammed bin Rashid Al Maktoum, vice president
of UAE and constitutional monarch of Dubai.
Construction started in 6 January 2004.
Completed in 2 December 2009.
Construction cost “USD $ 1.5 billion” (9,117,93,75,000.00 in Rs).
Chief Architect: Adrian Smith at SOM.
Developer: Emaar Properties.
Structural engineer: Bill Baker at SOM.
Main contractor: Samsung Engineering and Construction
Casting of Construction
The soil stratum of Dubai is very week so they had to excavate
up to 50m deep to get a hard rock structure.
But the rock that they found was fragile and saturated with
ground water and is having holes.
The engineers filled this holes with a viscous polymer slurry.
194 piles were constructed to avoid sinking of this structure.
Over 30,000 tons of steel were used.
About 250,000 m2 concrete was used.
Casting of Construction Continued
High performance concrete(HPC) is used which has Low
permeability and High durability.
C80-C60 cube strength concrete was used.
For reducing cracks due to high temperature concreting was
done only at night.
They used heavy pumps which can pump 25000 tons of
concrete to 150th floor in 14 minutes.
They completed every new floor in 3 days.
Casting of Construction Continued
The three wing shaped basement allow for greater
building height by buttressing one another by a central
It is called as Hexagonal Hub.
This hub is surrounded by the three wings.
These three wings afford the torsional
resistance and the twisting of the tower.

World's second highest
outdoor observation deck
The Burj Khalifa's water system supplies an average of
946,000 L of water per day through 100 km pipes.
An additional 213 km of piping serves the fire emergency
And 34 km pipe supplies chilled water for the air
The waste water system uses gravity to discharge water from
plumbing fixtures, floor drains, mechanical equipment and
storm water, to the city municipal sewer.
The air conditioning system draws air from the upper
floors where the air is cooler and cleaner than on the
At peak cooling times, the tower's cooling is equal to the
cooling which is produced by melting 13,000 tons of ice.
Condensate recovery system collects water condensate
from the air conditioning system and diverts it to an
It provides about 15 million gallons of water per year
To wash the 24,348 windows, a horizontal track has been installed
on the exterior of Burj Khalifa at levels 40, 73, and 109.
Each track holds a 1,500 kg bucket machine which moves
horizontally and then vertically using heavy cables.
Above level 109, up to tier 27 traditional cradles from davits are
The top of the spire, however, it is reserved for specialist window
cleaners, who brave the heights and high winds, dangling on ropes
to clean and inspect the top of the pinnacle.
Burj has 9 Refuge Rooms for every 30 floors which can resist
fire for more than 2 hours.
The Burj utilizes solar power, nearly 378 panels having an
area of 1020 sq.m.
These panels have the ability to heat 140,000 lit of water
when supplied with just 7 hours of day light.
The Evacuation system of Burj Khalifa is self controlled
whenever it recognizes smoke or fire it will automatically
puts out that by special mechanism.
Tallest structure ever built: 829.8 m (2,722 ft)
Building with most floors: 163.
World's highest elevator installation (situated inside a rod at
the very top of the building)
Highest vertical concrete pumping (for a building): 606 m
World's highest New Year display of fireworks.
Tallest Building built by man.
Several new techniques were introduced while
constructing burj khalifa.
The construction of the Burj Khalifa proves that
height doesn't matter in any civil engineering
