We've been following Chinese construction firm Broad Sustainable Building's ambitious plan to build the world's tallest skyscraper the city of Changsha for a while now, and it looks like they're making progress: the Chinese government has given the go-ahead for BSB to build Sky City, a 220-story, 2,750-foot skyscraper, the largest in the world. Even crazier, the Chinese firm is trying to build it in just three months.
The current record-holder, the Burj Khalifa in
Abu Dhabi Dubai, was constructed in five years, and even that took some impressive engineering. BSB wants to make Sky City possible by spending four months prefabricating the materials off-site, then erecting it all over the course of three months, starting this month. (The original plan was to start construction in December, but the project has apparently tied up in red tape for months.)
When complete, the building will be almost a city: 30,000 people will be able to take 104 elevators or a single six-mile ramp that curls through the interior toward a school, hospital, and housing. The projected pricetag for it all is $628 million. Not cheap, but considerably less than, say, the $1.5 billion Burj Khalifa.
Hopefully the project really does get completed in three months, so we can see the awesome building timelapse video that's almost certainly going to come out of it.
Where are they going to build it? Is it really going to be a stand alone city surrounded by the rural country as it is depicted? I really can't tell by reading the article. What am I missing? I would certainly like to see such a building in other countries if it is a success.
I'm sure there are smart people working on this. And yet, somehow, I'd prefer to move into a skyscraper that wasn't rushed.
China has some impressive building expertise: they built a mile long bridge in Harbin in two years while it took Detroit 2 years to build a 100 meter bridge. Of course, a section of one of the new bridges in Harbin fell over so hopefully this new skyscraper will be built according to code and with more than just rebarred cement.
The world tallest building done in 90 days using Chinese and Chinese based materials?
I only have the products I see imported to the US every day to use as an analog, so I wonder if I'd rather live in it, or be the 1'st human passenger on a North Korean space launch.
What happens if a plane hits it or there's a fire?
Imagine 30,000 people trying to escape a building all at once.
Damn scientific news site and uses FEET to measure height.
Interesting project (with all facilities inside) - one solution for overpopulation.
However - record speed building means bad quality.
Somethign this massive should also be built at a stable ground (no earthquakes), no tsunamis and hurricanes/tornadoes.
Also... this is another sign of chinese showoff politics - they have whole skyscrapers and towns abandoned - noone could afford the price to live there.
628m is cheap for china. Imagine a whole region of land filled with those - interconnected with skybridges.
Add some epic chinese high tech recycling, greenhouse floors for food and so on to have a way greener, dense futuristic city.
call me overly pessimistic, but I would not want to live within 2750ft of it if they are that focused on the timetable, as opposed to doing it right.
Case in point, how long was the burg khalifa's upper floors blocked off because of its botched construction.
838 meters. When will PopSci ditch the Imperial system?
According to the video, it's 7 months, not 3. I know this company's last project took 3 months so is this a new time schedule, or just a mix up with the time frame of the old project?
I would live in it. I would just buy a bunch of parachutes so I could jump from it when everything goes wrong and would like to live high enough to be able to jump. I would also demand a possibilety to be able to jump from a platform or so. The problem is probably the Chinese themselves. This could be done in Singapore effectively where farting is fined :). But in a country where everyone will do as they please and the owners will try to save money to increase profits I think it will become a nightmare.
For the Chinese it is the only way to go because otherwise they will not keep enough land to grow enough food.
The Chinese can build this so quickly beacuse they ignore workers safety.
That is the last thing the Chinese need is another big empty building, how about filling up some of those empty cities first
@Popsci, Burj Khalifa is in Dubai not Abu Dhabi. Anyway, interesting piece.
Position: Editorial Department
Burj Khalifa is also big empty building.
Palm Jebel Ali is a big empty man-made island.
Why pick on China?
HenryT2 - The video says 7 months because it included the 4 months of pre-fabricating materials off site into its time line. they plan on actually building/assembling the tower in 3 months.
Ya know if this beast of a building gets toppled over one day, it will be another 1000 years of mix communication, lol.
I don't think I'm picking on the Chinese, its just they don't need another huge empty building, the construction bubble the Chinese are making is huge compared to the U.S. bubble, currently they are at 52% of GDP on BUILT units, at the height of the U.S. bubble we were at 16% of GDP on SOLD units...
cant wait to see how this one turns out
Thanks for clearing that up.

This story and the comments made me laugh. lol where are they going to find tenants to fill this thing? lololol Im laughing so hard right now.... hahah!!! People are looking at this story and going...what the?!? The company building it and the Chinese dont understand that people are scared. lol this is so funny. Tourists who come to see it will say "Its nice and so tall! wow!...These are really good binoculars! So clear! The Chinese really know how to make good binoculars!...How come there are no people walking around on the street?!??"
The bigger it is, the more opportunities for something to go wrong, and the more assumptions that go into its construction. You know, assumptions like the steel doesn't have weakening inclusions in it or the concrete wasn't deficient in any way. Unfortunately, with the rampant nature of corruption in China, multiplied by the thousands of entities that will go into constructing this beast, you have the perfect breeding ground for an epic fail.
Have we not seen Chinese bridges fail, whole building topple over, and high speed trains wreck because of corruption? I wouldn't go anywhere near this monstrosity.
A Jetson type car would be helpful. The elimination of elevators would simplify construction .
