Inside the Burj Dubai - World's tallest building - Burj Khalifa (Burj Dubai)

Fact Sheet - Burj Dubai

Currently the worlds tallest building and tallest man-made structure, Burj Dubai is at the centre of Downtown Burj Dubai, the flagship mega-project of Emaar Properties in Dubai. The final height of the tower will be revealed on its completion in 2009.

With a development value of over US$1 billion, Burj Dubai, when completed, will fulfil all the criteria of the Council on Tall Buildings and Urban Habitat (CTBUH), which ranks the worlds tallest buildings on the basis of spire height, the highest occupied floor, roof height and pinnacle height.

At a current height of over 800 metres (2,625 ft), Burj Dubai has now also scaled over 160 levels, the most number of storeys in any building in the world. Burj Dubai has already surpassed the height of the KVLY-TV mast in North Dakota, USA - 628.8 metres (2,063 ft), which held the distinction of being the worlds tallest man-made structure. Burj Dubai is taller than Taipei 101 in Taiwan, which at 508 metres (1,667 ft) has held the tallest-building-in-the-world title since it opened in 2004. The tower also surpassed the 31-year-old record of CN Tower, which at 553.33 metres (1,815.5 ft) has been the worlds tallest free-standing structure on land since 1976.

Leveraging on the advancements in construction engineering, Burj Dubai undertook height enhancement in 2008 and is also upgrading its interior finishes. International designers from California have revisited the designs to make the residences more attractive and functionally superior.

In just 1,325 days since excavation work started in January, 2004, Burj Dubai became the tallest free-standing structure in the world. More than 11,000 consultants and skilled construction workers are employed on site, and the worlds fastest high-capacity construction hoists, with a speed of up to 2 m/sec (120 metres/min), were used to move men and materials.

When completed, the tower will have used 330,000 cubic meters of concrete, 39,000 metric tons of steel rebar and 142,000 sq m of glass and 22 million man hours.

The design inspiration for Burj Dubai is drawn from the desert flower, Hymenocalis, and incorporates patterning systems that are embodied in Islamic architecture. The tower is designed as three petals arranged around a central core. As the tower rises from the flat base, the petals setback in an upward-spiraling pattern.

Burj Dubais structure has employed the latest advances in wind engineering, structural engineering, structural systems, construction materials and construction methods. It will have a high performance exterior cladding system to withstand the harsh summer temperatures.

A mixed-use tower, Burj Dubai features 2 million sq ft of residential and over 220,000 sq ft of prime business space, in addition to the Armani Hotel Dubai, and Armani Residences Dubai, luxury hospitality ventures by Emaar in association with haute couture major Giorgio Armani S.p.A.

The tower offers recreational facilities and entertainment venues including four luxurious pools and a cigar club, a library, exclusive residents lounge, serviced residences, fitness facilities and an observatory deck on level 124, At The Top opening to impressive views of Dubai. The tower will also have a large Office Annexure.

What is Burj Dubai?

Currently under construction - Burj Dubai is set to be the most prestigeous square mile of real estate on the planet! At its centrepiece stands the iconic Burj Dubai Tower, set to be the worlds tallest building upon completion in September 2009. This mammoth structure will be mostly residential; but will also be home to the worlds highest observation deck at a vertigo inducing 517m high, as well as the worlds first 6 star rated Armarni Hotel. Shadowed by the tower itself, across a massive man made lake will be home to the 'Supertall' Lake Hotel, the worlds largest ever shopping mall, over 70 highrise buildings and a beautiful 'old town' style village. All of the following will be finished by the end of 2009.

Current records

Tallest structure: 818 m (2,684 ft) (previously KVLY-TV mast - 628.8 m (2,063 ft))
Tallest freestanding structure: 818 m (2,684 ft) (previously CN Tower - 553.3 m (1,815 ft))
Building with most floors: 160 (previously World Trade Center - 110)
World's highest elevator installation

Worlds fastest elevators at speed of 64 km/h or 18 m/s (59 ft/s)[23] (previously Taipei 101 – 16.83 m/s)

Highest vertical concrete pumping (for a building): 601 m (1,972 ft) (previously Taipei 101 - 449.2 m (1,474 ft))

Highest vertical concrete pumping (for any construction): 601 m (1,972 ft)[24] (previously Riva del Garda Hydroelectric Power Plant - 532 m (1,745 ft)

The first world's tallest structure in history to include residential space

Note: Additional records for tallest skyscraper are considered unofficial. On 20 July

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 Ryungyong [sic] project. Taipei 101 is thus officially the world's tallest until that happens."
