Burj Dubai exterior complete

Dubai, October 1, 2009

Exterior cladding for Burj Dubai, the world’s tallest building being developed by Emaar Properties, a global property developer, is now complete.

The tower has accomplished a world record for the highest installation of an aluminium and glass façade. The total weight of aluminium used on Burj Dubai is equivalent to that of five A380 aircraft and the total length of stainless steel bull nose fins is 293 times the height of Eiffel Tower in Paris.

The last cladding panel numbered 24,348, weighing 750 kg and 1160mm x 6400mm in height was placed at a height of over 662 metres (2172 ft), thus accomplishing the mammoth task of cladding the world’s tallest building.

Arabian Aluminium Company in association with Hong Kong based Far East Aluminium began exterior cladding of Burj Dubai in May 2007, and the vast project has involved more than 380 skilled engineers and on-site technicians.

A mixed-use tower featuring residences, corporate suites, and the world’s first Armani Hotel and Armani Residences, Burj Dubai is on course to be completed later this year with work on interiors progressing simultaneously.

With a total of 24,348 cladding panels over a total curtain wall area of 132,190 sq m, Burj Dubai’s shimmering exterior minimises heat transmission and saves energy.

The total 103,000 sq m of glass used in the cladding panels can cover 14 standard football pitches and the 15,500 sq m of embossed stainless steel used can cover 34 National Basketball Association specified basketball courts.

The total length of gaskets – 2,050,000 linear metres – if laid end to end is about the distance from Dubai to Damascus in Syria (2,052 km).

The cladding materials were specially made using advanced engineering techniques and include high-performance reflective glazing, aluminium mullions and textured steel spandrels with vertical stainless steel tubular fins.

The cladding accentuates Burj Dubai’s height while lending it a shimmering slenderness. Panels of more than 18 different strength specifications and over 200 sizes have been used for Burj Dubai, all of them double-glazed and factory-sealed.

The world record for the highest aluminium façade installation was achieved by Burj Dubai earlier in the year at a height of 512 metres, less than one year after work started.

Mohamed Alabbar, chairman, Emaar Properties, said that the completion of cladding work at Burj Dubai was a milestone both for Burj Dubai and the science of high-rise engineering.

“Burj Dubai’s construction and engineering techniques are unprecedented, and they are our contribution to the science of high-rise development,” Alabbar said. “The cladding work has involved considerable innovation – vast amounts of research and simulation have pioneered advanced materials and installation techniques.”

Alabbar added: “One of the key considerations when designing the cladding was maximizing resistance against heat transmission from the sun and improving energy efficiency within the tower.

“The materials used, as well as withstanding the harsh summer temperatures keep heat out of the building, allowing for a significant reduction in the amount of air-conditioning required. Burj Dubai’s exterior is a model for high-rise developers creating sustainable buildings of the future.”

The cladding work for Burj Dubai is the largest project of its kind undertaken by Arabian Aluminium Company, (Aluminium Division of Al Ghurair Construction).

Bashar Kayali, General Manager, Arabian Aluminium Company, said that under the joint venture with Far East Aluminium, Arabian Aluminium undertook cladding work on an accelerated pace right from the design stage where the cladding of the tower was divided into multiple zones.

At the initial stage of installation, Arabian Aluminium was progressing at the rate of about 20 to 30 panels per day and eventually it achieved as many as 175 pa
