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.Slide4

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.Slide5

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 designThe floor plan of the tower consists of a tri-axial, “Y” shaped plan, formed by having three separate wings connected to a central coreSlide6

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.Slide7

Architecture

The architecture features a triple-lobed footprint, an abstraction of the Hymenocallis flowerThe tower is composed of three elements arranged around a central

coreThe 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 spireSlide8

Scope

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 groundSlide9

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.Slide14

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.Slide15

Burj Khalifa Construction team

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 SrilankanSlide16

Change in Design

The final construction was 100 meters higher than the original designThe changes were made in interior design on the demand of Armani hotels

16Slide17

Bad Employee Management

In 2006, the project, which had till then been progressing slightly ahead of schedule, fell behind schedule. Workers from countries like India, Pakistan, and Bangladesh, were used to construct the towers and they complained that they were being paid very low wages.

17Slide18

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 elevatorsTo 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.18Slide19

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 application19Slide20

From the point of quality : The project is successful

The net profit increased 10 times compared to 200920Slide21
