The worldâ„¢s man made tallest tower

BURJ KHALIFA

Presented BY
VENKATESH


INTRODUCTION

Itâ„¢s the new tallest tower in the world.

Construction began on 21 September 2004.

Height of the Tower is 828m(2717ft).

The total cost for the Burj Khalifa project and implimentation was about US$1.5 billion.

The tower is designed to withstand high winds and seismic events.




INSPIRATION



Designers were motivated by the Hymenocallis genus's spidery, layered form.

A Hymenocallis flower showing six spokes, as pattern for the three-lobed design.

The Burj Dubai makes use of a "buttressed core" and has a modular, Y-shaped structure.



ARCHITECTURE AND DESIGN


The tower is designed by Skidmore, Owings and Merrill.

Adrian smith was chief architect for burj dubai.

The tower is composed of three elements arranged around a central core.








CONSTRUCTION


The tower was constructed by a Samsung Engineering & Construction.

Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes.

192 piles, with each pile is 1.5 metre diameter x 43 metre.

More than 50 m (164 ft) deep.

The concrete pressure during pumping to this level was nearly 200 bars.



Structural Elements ” Elevators, Spire, and More


A combination of several important technological innovations and innovation structural design methods.


Foundation
Podium
Structural System
Exterior Cladding
Spire
Mechanical Floors
Window Washing Bays
Broadcast Floors
Mechanical, Electrical & Plumbing
Fire Safety
Elevators & Lifts



FOUNDATION


The superstructure is supported by a large reinforced concrete mat.
The mat is 3.7 meters thick.
A high density, low permeability concrete was used in the foundations.
Cathodic protection system under the mat, to minimize any detrimental effects form corrosive chemicals in local ground water.




EXTERIOR CLADDING


Aluminum and textured stainless steel spandrel panels and stainless steel vertical tubular fins.

26,000 glass panels used.

Withstand Dubai's extreme summer heat.

World War II airplane engine was used for dynamic wind and water testing.



SPIRE


Telescopic spire comprised of more than 4,000 tons of structural steel.

The spire was constructed from inside the building and jacked to its full height of over 200 metres (700 feet).

The spire is integral to the overall design.

The spire also houses communications equipment.



MECHANICAL , ELECTRICAL &PLUMBING

The tower's water system supplies an average of 946,000 litres (250,000 gallons) of water daily.

At peak cooling, Burj Khalifa will require about 10,000 tons of cooling.

Dubai's hot, humid climate combined with the building's cooling requirements creates a significant amount of condensation.

The tower's peak electrical demand is 36mW, equal to about 360,000 100 Watt bulbs operating simultaneously.



ELEVATORS & LIFTS

57 elevators and 8 escalators.
World's fastest elevators at speed of 64 km/h.
World's highest elevator installation.


WORLD RECORDS


Tallest building in the world.

¢Â  Tallest free-standing structure in the world.

¢Â  Highest number of stories in the world.

¢Â  Highest occupied floor in the world.

¢Â  Highest outdoor observation deck in the world.

¢Â  Elevator with the longest travel distance in the world.

¢Â  Tallest service elevator in the world.
