When we brought you this story back in June, the title read "World's Tallest Skyscraper To Be Built....in 90 Days! "
Well, as any architect knows, first estimates are never accurate. Broad Sustainable Building (BSB), the design firm behind Sky City, soon to be the world's tallest skyscraper, has professed that the building will now be built at the positively glacial pace of 210 days (7 months instead of 3).
As we explained last time, Sky City will shoot up to its 838-meter (2,750-ft/220-story) height thanks to its pre-fabricated assembly (up to 95% of the materials will be assembled in modular form before on-site construction even begins). BSB also claims that it will be sustainable and earthquake proof.
According to a fascinating Wired interview with BSB's founder and Chairman, Zhang Yue (check it out), the foundation is scheduled to be laid in November and should be complete by March 2013.
Read on after the break for more of Sky City's impressive record-breaking stats and sustainability chops...
