The highest building in the world is the Burj Khalifa in Dubai. Almost 25000 windows covering more than 1 million square feet of space. That kind of building should be cleaned from professionals that are trained climbers, as well. It is not an easy task, not at all!. We are talking about someone to hang from such a high that could kill someone who is just looking at it. Then washing and polish the windows. Can you imagine?
Three horizontal tracks have been installed on the exterior of the building to assist the progress for the windows cleaning and maintenance of the building. Each of these paths is holding a large bucket machine, held by cables, which can move both vertically and horizontally around the building.
Above the 109th floor the things get complicated. Traditional bassinets, are manned by one or two person teams operating with more traditional skyscraper window cleaning methods.
The final tiers of the building are subject to extreme weather conditions, as well. There are not cleaned by real people. This upper levels are cleaned from automated, unmanned machines.
In case of necessity of maintenance or cleaning of the building’s glass spire, then professional windows cleaners and maintenance personnel will hang out there, on 828 m height.
36 experts are hired to take care of the windows and the exterior of the building. It takes them roughly 3 months for the whole Burj Khalifa. The experts are hired from numerous cleaning companies and the best ones are chosen to take care of such serious job. Can you imagine the costs for such service? It won’t be so affordable like the prices of Mayfair cleaners.
