Burj Dubai's High-altitude Cranes Dismantled As Opening Date Nears

| Labels: , , ,
Burj Dubai, the world's tallest building, is nearing completion, following the dismantling of the last high-altitude crane used in its construction.

In preparation for its Jan 4, 2010, opening, the Burj Dubai construction team is now concentrating on the interiors and landscaping.

They completed the tower's external cladding recently, according to a statement from Emaar Properties which is developing the mixed-use tower at the centre of the Downtown Burj Dubai mega project.

Three huge tower cranes were used in moving construction materials up to Level 156 of Burj Dubai.

In all, the cranes lifted over 63,300 tonnes of steel reinforcement, and were operational for a total of 45,000 man-hours.

A team of 35 skilled technicians manned the cranes, a critical component of the 11,000-strong workforce devoted to the construction of the skyscraper.

Emaar said the operators of the cranes worked at dizzying heights of more than 700 metres, almost double the height of the Empire State Building.

What is Burj Dubai?

What's at 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.

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."
