• 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.
Why Burj Dubai becomes Burj
Khalifa??
• 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
SCOPE CONTINUED..
Burj Khalifa (Burj Dubai) is the tallest man-made structure ever built.
The mixed use development will include residential units, offices, hotels and residential
apartments.
Burj Khalifa was planned by the Dubai government with the aim of becoming a hub for
finance, trade and tourism in Middle East

“Iron Triangle”, a criterion which measures the project based on three
perspectives:
COST
TIME
QUALITY
The initial planned costs of the project was 876 million dollars. The
final cost, however, was approximately 1.5 billion dollar
The final construction was 100 meters higher than the original design
Changes in interior design planning were another reason for the
increase in costs
11
Originally, the duration of project was set for forty-seven months, starting from February 2005 to December
2008
The Burj Khalifa project was completed nine months later, on September 2009.
Economical decline halted construction for four months in 2008.

• Temperature rising over 45 degrees, wind, sun and gravity
• Rise in price of raw materials and special kind of reinforced
concrete for construction, special type of glass panels with
aluminium used to protect this structure from wind, dust and sun.
• Construction cost.
Cont’d….
• Emaar was also affected by the downturn in the real estate market in
Dubai. In late 2008, the price of property at Burj Dubai slumped by
about 50%-60%, while prices in the surrounding Downtown Burj
Dubai fell by at least 22%
• First of all, a rise in prices of raw materials had gone up significantly
due to the downturn of the global economy in 2008.
• According to report of Global Informing (2008), the price of iron had
increased by 75% within a year. Other materials such as aluminum
and cement also increased Increase of price of commodities caused a
factor to increase construction cost.
• Burj Khalifa was truly an international collaboration between more
than 30 on-site contracting companies from nations around the
world.
• At the peak of construction, over 12,000 workers and constructors
were on site every day, representing more than 100 nationalities.
• Workers include mostly Indian, Pakistan and Srilankan
Change in Design
• The final construction was 100 meters
higher than the original design
• The changes were made in interior
design on the demand of Armani
hotels

• The engineers of the tower worked the design of the structure to avoid the two major
challenges; wind and gravity.
• The highest-risk part of the Burj Khalifa is its high speed elevators
• To ensure safety, the Burj Khalifa features a home automation system which consists of
LCD panels that display detailed emergency information to specified groups of building
occupants.

Samsung engineering and Besix, introduced new technologies based on previous experiences with tall
building construction.
Following technologies were used for building Burj Khalifa :
• The ETABS software developed by Computers & Structures Inc., of USA was used for the analysis and
design.
• Prolog Manager is a Windows-based construction project management application
19
From the point of quality : The project is
successful
The net profit increased 10 times
compared to 2009
