Nope, no worries there. I would feel totally safe atop this building.

Sky City: Chinese Company BSB to Build the World’s Tallest Building… In Just 90 Days?!
by Timon Singh, 06/18/12

Even since the current world’s tallest builing – the Burj Khalifa in Dubai – was completed, there has been a constant battle to build the world’s next tallest building. The current record holder stands tall at 828 meters and took five years to build, but a Chinese company called Broad Sustainable Building (BSB) aims to smash that record by building the 838 meter eco-friendly Sky City tower, in Changsa, China in a mere 90 days – and they’re planning to use prefab building techniques to construct the skyscraper so quickly!

According to source CNNgo, the Sky City development is being spearheaded by Chinese construction company Broad Sustainable Building (BSB) who aim to build the skyscraper in Changsha, the provincial capital of Hunan Province for a ‘mere’ $628 million.

If the company meets its deadline, then the 220-story structure will overtake the Burj Khalifa to become the tallest structure in the world. Construction is scheduled to start in November 2012, with the tower being completed by January 2013, but how will they get it up so fast?!

BSB has already established a reputation for themselves by erecting a 30-story hotel in 360 hours (see below video) in December 2011. They claim that their “innovative construction techniques” help them to meet such bold targets, including constructing buildings with prefabricated components from their factory. In the case of Sky City, this means that 95% of the building will be constructed in a factory before the construction team break grounds, allowing the pre-finished pieces to be assembled on site much more quickly, sort of like a massive 3D puzzle!
