Window washing the Burj Khalifa, Dubai

With a house that is just sufficient for us to live in maintenance is still a pain in the neck. Washing the glass-doors and windows though they are very few is a very daunting task. Imagine doing the same to 24,000 window panes, the highest ones that sit atop 800m in the air!

We are talking about the 24,000 windows of the world's tallest building currently the Burj Khalifa in Dubai. The architectural masterpiece is a brilliant design with measures to counter the wind forces with a streamlined body on all sides to avoid the “Bernoulli Principle” that would create drag force from the vortexes while sucking the building causing it to sway and collapse.

Like most beautiful inventions, this one has its drawbacks too. It has over 24,000 windows but they won't clean themselves. With dust settling on the windows, the need for maintenance is very high. For this specific job, window washers who are no less courageous than a daredevil stuntman buckle themselves while cleaning each of the pane meticulously from top to bottom. By the time the building is cleaned completely, which take around 90 days, the team would have to start again at the top.

They also have to take care not to drop anything because even the smallest object like a pen dropped from this height would reach speeds that could be fatal on impact. Take a look at the hard-work of these men in the video.
