I found some interesting facts! HSBC Building in Hong Kong was built on similar technology - 44 floors were built in one year. Why is this technology has not become a revolution 30 years ago?

Well, it isn't revolution. 40 floors in one year and 200 floors in 4 month are different things...

BTW somilar technology was also applied in China couple years ago, when 30- floor tower was built in 2 weeks.

I think that building in Hong kong has nothing to do with Sky City construction technology, but if you talk about construction speed, the Empire State Building has probably been the fastest skyscraper construction ever, and that was in 1930!

Of course I saw the video, that's why i commented in the first place.

It is practically impossible to land a helicopter at 600 meters above ground, practically impossible, the winds will not allow it. The fact that the platform will be at the side of the building, instead of the top, with 360 degree of space around, makes it even more unlikely.

PS: Just because it is in the presentation video, it doesn't mean it will be in the final product as well. Everything is improved during construction.

they had even more helicopter pads on the building but seem to have removed most of them in the newest render. now only one of them seems to be left, either just for show and they won't build it or they try to get it to work out somehow and not give up on the idea completely

From the video it looks like the tallest helipad is at around 600m. It's similar to the height of the platform of Kingdom Tower. As we know it supposed to be a helipad but some pilots said it would be too dangerous to land on it so they turned in the private terrace. Still nobody said it's impossible. With the right weather and good pilot it should be doable. Also while Jeddah is next to a sea Changsha is deep inland China so the wind may be different there. Flight safety regulations are also not without a significance as they probably differ in both countries. Maybe crazy chinese pilots takes bigger risks on daily basis

It might be added to the render just for fun of course, but I will wait till the building is ready instead of making unfounded assumptions.

It's pretty much this. Landing on the ground so close to a building is challenging in it's self. That is the main reason why most helipads are at the very top of buildings or out in a very open space. What happens is, the air that the Helicopter is producing from it's own rotors will bounce off the wall and come back at the helicopter and try to flip it over. Without a wall or building next to the helipad, the winds just go outward and away from the Helicopter. Now add in the very high winds from being up over 500m and your just looking for a disaster to happen. There might be 10 pilots in the world that would even attempt that type of high landing and of those 10, 6 of them would abort once they got close to the tower, 1 would crash into the tower, and maybe 3 of them would actually pull it off and that's if they had a very, very powerful Helicopter.

Changsha has to be the most EPIC city in China now. They just barely finished their first +200m building with many more to come. 2x supertalls and a 400m tall starting up(wharf IFC). The largest urban complex in China (bechean project) and now Sky City. Just amazing!!!

Has nothing to do with Shenzhen, Tianjin, Shanghai and Hong Kong.
A cheap lego design won't make this city the best in China

But changsha will get a world wide attention with this tower, no doubt.
And to me it doesn't look like a cheap lego design.

the method is less expensive because of innovation, i wouldn't call it cheap. it might be the first of many buildings, a step into the future if you will. if this concept goes well i am sure cities like Tianjin and Shenzhen are among the first to also build skyscrapers with this method to fill in for the need of buildings, maybe not this size, but if it works we are about to see many 200m-400m buildings pop up in these cities.

Well it is literally cheap because the technology make it so. It's also cheap as it is after all a modern take on commie block.

Yeah, after all, technology is all about bringing down the cost of doing things that were previously impractically expensive.

Age of prefab buildings, skyscrapers and possibly moonbase coming?
