Hello Friends, Here is a complete phase of construction of Burj Dubai with a picture of each months. This is a huge mail so its take time to open (Depend upon your Internet connection Speed) I think every one is enjoying this mail.
The total budget for the Burj Dubai
project is about US$4.1 billion and for the entire new
'Downtown Dubai', US$20 billion. Mohamed Ali Alabbar, the CEO of Emaar
Properties, speaking at the Council on Tall Buildings and Urban
Habitat 8th World Congress, said that the price of office space at
Burj Dubai had reached $4,000 per sq ft (over $43,000 per sq m)
and that the Armani Residences, also in Burj Dubai, were selling for $3,500 per
sq ft (over $37,500 per sq m).
Burj Dubai reached its final height
of 818 m (2,684 ft) on January 18, 2009.

Note: Additional records for
tallest skyscraper are considered unofficial. On July 20, 2007, the head of the
Council on Tall Buildings and Urban
Habitat (CTBUH), Antony Wood, said "We will not classify it as
a building until it is complete, clad and at least partially open for business
to avoid things like the Ryungyongproject. Taipei
101 is thus officially the world's tallest until that happens."

Though unconfirmed, Burj Dubai has
been rumoured to have undergone several planned height increases since its
inception. Originally proposed as a virtual clone of the 560 m
(1,837 ft) Grollo Tower proposal for Melbourne,
Australia'sDocklands waterfront development, the tower was
redesigned with an original design by Skidmore, Owings and Merrill discussed
below. Marshall Strabala, an SOM architect who worked
on the project until 2006, recently said that Burj Dubai was designed to be
808 m (2,650 ft) tall.However, although contradictory
information abounds regarding the official height of the building, the structure
will most likely acquire the title of world's tallest structure upon completion
The design architect, Adrian Smith,
felt that the upper-most section of the building did not culminate elegantly
with the rest of the structure, so he sought and received approval to increase
it to the currently planned height. It has been explicitly stated that this
change did not include any added floors,
which is fitting with Smith's attempts to make the crown more slender. However,
the top of the tower has a steel frame structure, unlike the lower
portion's reinforced concrete. The developer, Emaar, has stated this steel section may be
extended to beat any other tower to the title of tallest; however, once the
tower is complete, height increases will not be recognised.
Properties announced on June 9, 2008 that construction of Burj Dubai
was delayed by upgraded finishes and will be completed only in September 2009.
An Emaar spokesperson said "The luxury finishes that were decided on in
2004, when the tower was initially conceptualized, is now being replaced by upgraded
finishes. The design of the apartments has also been enhanced to make them more
aesthetically attractive and functionally superior".
Architecture and design
The tower is designed by Skidmore,
Owings and Merrill, who also designed the Sears
Tower in Chicago
and the Freedom Tower in New York City,
among numerous other famous high-rises. The building resembles the bundled tube
form of the Sears
Tower , but is not a tube
structure. The design of Burj Dubai is reminiscent of the Frank Lloyd Wright vision for The Illinois,
a mile high skyscraper designed for Chicago ,
According to Marshall Strabala, an
SOM architect who worked on the building's design team, Burj Dubai was designed
based on the 73-floor "Tower Palace Three", an all-residential
building in Seoul,
In its early planning, Burj Dubai was intended to be entirely residential.
Emaar Properties has also engaged GHD,
an international multidisciplinary consulting firm, to assist with the design,
review and assessment involved in the construction process.
The design of Burj Dubai is derived
from patterning systems embodied in Islamic architecture, with the triple-lobed
footprint of the building based on an abstracted version of the flower Hymenocallis.
The tower is composed of three elements arranged around a central core. As the
tower rises from the flat desert base, setbacks occur at each element in an
upward spiralling pattern, decreasing the cross section of the tower as it
reaches toward the sky. At the top, the central core emerges and is sculpted to
form a finishing spire. A Y-shaped floor plan maximizes views of the Persian Gulf.
Viewed from above or from the base, the form also evokes the onion domes
of Islamic architecture. During the design process, engineers rotated the
building 120 degrees from its original layout to reduce stress from prevailing
winds. The tower, at its tallest point, sways a total of 1.2 m
The exterior cladding of Burj Dubai
will consist of 142,000 m2 (1,528,000 sq ft) of
reflective glazing, and aluminium and textured stainless
steelspandrel panels with vertical tubular fins. The cladding
system is designed to withstand Dubai 's
extreme summer temperatures. Additionally, at its projected height, the
exterior temperature at the top of the building will be noticeably cooler than
at its base, by 6 °C (11 °F).
The interior will be decorated by Giorgio
Armani. An Armani Hotel, the first of four by Armani, will occupy the
lower 37 floors. Floors 45 through 108 will have 700 private apartments
on 64 floors (which, according to the developer, sold out within eight hours of
going on sale). An outdoor zero-entry swimming pool will be located
on the 78th floor of the tower. Corporate offices and suites will fill most of
the remaining floors, except for a 123rd floor lobby and 124th floor (about
440 m (1,444 ft)) indoor/outdoor observation
deck. The spire—itself over 200 m (700 ft) tall—will hold communications
It will also feature the world's
rising and descending at 18 m/s (59 ft/s). The world's current
fastest elevator (in the Taipei
101) travels at 16.83 m/s (55.2 ft/s). Engineers had considered
installing the world's first triple-decker elevators, but the final design
calls for double-deck elevators. A total of 56
elevators will be installed that can each carry 42 people at a time.
Outside, and at a cost of Dh 800
million (US $ 217 m), a record setting fountain system is to be designed by WET Design, the California-based
company responsible for the fountains at the Bellagio
Hotel Lake in Las Vegas.
Illuminated by 6,600 lights and 50 colored projectors, it will be 275 m
(900 ft) long and will shoot water 150 m (490 ft) into the air,
accompanied by a range of classical to contemporary Arabic and world music. On
October 26, 2008 Emaar announced that based on results of a naming contest the
fountain would be called the Dubai Fountain.

The tower is being constructed by a
South Korean company, Samsung Engineering & Construction which also built the Petronas Twin Towers and the Taipei 101. Samsung
Engineering & Construction is building the tower in a joint venture with
Besix from Belgium
and Arabtec from UAE. Turner is the Project Manager on the main
The primary structural system of
Burj Dubai is reinforced concrete. Over 45,000 m3
(58,900 cu yd) of concrete, weighing more than 110,000 tonnes (120,000 ST;
were used to construct the concrete and steel foundation, which features 192
piles buried more than 50 m (164 ft) deep. When completed, Burj
Dubai's construction will have used 330,000 m3
(431,600 cu yd) of concrete and 39,000 tonnes (43,000 ST;
38,000 LT) of steel rebar (enough to extend over a quarter of the way
around the world if laid end-to-end); and construction will have taken 22
million man hours.
As construction of the tower
progresses, it becomes increasingly difficult to vertically pump the thousands
of cubic metres of concrete that are required. The previous record for pumping
concrete on any project was set during the extension of the Riva del Garda
Hydroelectric Power Plant in Italy
in 1994, when concrete was pumped to a height of 532 m (1,745 ft).
Burj Dubai now holds this record as of August 19, 2007, as it has a height of
536.1 m (1,759 ft), to hold the record for concrete pumping on any
project; and as of November 8, 2007 concrete was pumped to a delivery height of
601 m (1,972 ft).
Special mixes of concrete are made
to withstand the extreme pressures of the massive weight of the tower; as
typical with reinforced concrete construction, each batch of concrete is tested
and checked to see whether it can withstand certain pressures. The head of
Concrete Quality Checking on the Burj Dubai project is Alam Feroze, who is in
charge of concrete on the whole project. The concrete pumps, pipelines and
booms are provided by Putzmeister, of Aichtal,
The consistency of the concrete on
the project is essential. It was difficult to create a concrete that could
withstand the thousands of tonnes bearing down on it and also withstand Persian Gulf
temperatures that can reach 50 °C (122 °F). To combat this problem,
the concrete is not poured during the day. Instead, ice is added to the mixture
and it is poured at night when it is cooler and the humidity is higher. A
cooler concrete mixture cures evenly throughout and therefore is less likely to
set too quickly and crack. Any significant cracks could put the whole project
Burj Dubai is being built primarily
engineers and workers from India ,
Pakistan , Bangladesh , China
and the Philippines .
Press reports indicate that skilled carpenters
at the site earn US$7.60/day, and laborers earn US$4.00.
On March 21, 2006, around 2,500
workers upset over buses that were delayed for the end of their shifts rioted,
damaging cars, offices, computers, and construction equipment. A Dubai Interior
Ministry official said the rioters caused almost US$1m in damage. Most of the
workers involved in the riot returned the following day but refused to work.
As of June 17, 2008 there are 7,500
skilled workers employed in the construction of Burj Dubai.
Burj Dubai has been designed to be
the centerpiece of a large-scale, mixed-use development that will include 30,000
homes, nine hotels such as the Burj Dubai Lake Hotel
& Serviced Apartments, 3 hectares
of parkland, at least 19 residential towers, the Dubai Mall,
and the 12-hectare (30-acre) man-made Burj Dubai Lake.
The silvery glass-sheathed concrete
building will return the title of Earth's tallest free-standing structure to
the Middle East—a
title not held by the region since 1311 CE when Lincoln
Cathedral in England surpassed the height of the Great Pyramid of Giza, which had held the
title for almost four millennia.
The decision to build Burj Dubai is
reportedly based on the government's decision to diversify from a trade-based
economy to one that is service- and tourism-oriented. According to officials,
it is necessary for projects like Burj Dubai to be built in the city to garner
more international recognition, and hence investment. "He [SheikhMohammed bin Rashid Al Maktoum]
wanted to put Dubai
on the map with something really sensational," said Jacqui Josephson, a
tourism and VIP delegations executive at Nakheel Properties.
