Read my latest post above... do you actually believe they could apply the same construction pace on an 800m tall building?

There is a lot more truth in that statement than many people realize.

Use of prefabricated steel pieces, World Trade Center NYC, 1970



J97 and the other buildings are surely a new generation in prefabricated construction works, but in no way an "innovation"

WTC took more than 5 years to construct. Quit being obtuse.

Some people just choose to ignore facts, haters gonna hate no matter what, keep arguing about it is a waste of time.

I'm pretty impressed with their speed too, the Chinese New Year holiday ended on the 14th so they did roughly ten floors in ten days.

After the foundations were done, the towers topped out within 2 1/2 years. You are the one being obtuse and narrow minded here.

Haters? Actually, I enjoy this project a lot, lol. I'm just trying to be objective here instead of building dream castles in the clouds.

Btw you guys are ignoring the facts, not me

keep in mind that some constructions didn't seem to really slow down much at all (eg: china chuneng tower) on chinese new year, while others stayed slow for even longer than that (eg: Wuhan Greenland Center). It is hard to just guess how many active days we got in that time, however if we say they didn't slow down at all over CNY, they still made a solid speed, so this project is really going forward and the next update whenever it will come will give us a better understanding of how well exactly it is coming along. Also like someone said that this method of construction also makes it easier to finish the building interior much faster as well makes me think that it might be done by the end of the year. After all even if it is only the current slowest speed (work over CNY) it would still top out quite a bit before the year is done.

So reducing construction time from 2.5 years to less than a year isn't an "innovation"? You are the ignorant narrow-minded one here. Haters gonna hate.

It's not an innovation, but it's an improvement. They further perfected an existing principle and made it twice as efficient.

-edit- It's a nitpicky argument, but "innovation" comes from the Latin "novus" = "new", and Broad's technology is not exactly new, they just took an existing idea and made it better.

That's what the word "invention" is for. Innovations can be inventions, or existing concepts that are vastly improved, such as tablets, smartphones, and high-speed rail.

does it really matter in the end though? if it works it will change so many things and make so many tall buildings possible for cheaper and faster that it will completely change the world of construction once established we can all agree that if this technology is one of the most exciting things to keep an eye out on, whatever terminology we prefer to use.

1970 vs. 2014. That's some 44 years of history, development and research in construction methods. Things go a lot faster nowadays, but it is still following the same principle.

@KillerZavatar
Yeah, I think it's awesome, too, I was just nitpicking that they're not actually doing something entirely new, they just upped the efficiency of pre-fab building construction. (Which in itself is impressive enough, especially for buildings of this size.)

We will see how it ends up, but prefab supertalls surely are an innovation, WTC was not built in a true prefab method, just had some prefab parts, so had a conventional speed. Huge difference.

It seems like the slow construction speed in 2013 might have something to do with this:
Quote:
3. 97-storey Small Sky City Has Passed the Administrative Inspection Procedures on the Seismic Design of tall Buildings Beyond Code Limits (Dec.) This is a 220,000m2 building complex with residence, office, commerce, entertainment & sport functions. The building is equipped with super energy conservation technologies such as 200mm thermal insulation wall, 4-paned window, heat recovery fresh air machine, cooling, heating and power system. The building adopts super purification technologies like 100% fresh air, 99.9% PM2.5 filtration. Super white glass windows are to be used, and the viewing color remains unchanged. It will be the first super highrise in this world marked with “four-supers” of super energy conservation, super purification, super white glass and super height.
Its finally out of administrative limbo now

My believes have nothing to do with it. If they build it I will believe it. I said that IF the same elements and technique is used the pace should be similar. But there's still many if's there.

How much of the building was usable when it was topped out ?

You are the one compared BSB's prefab building to the WTC, ignoring the fact that the latter is a built on site tower not unlike supertalls built today. Does it have all the components made in a factory, all utilities installed in modules, and shipped to site for final assembly only? No.

I think in that case nothing is innovative then, the 787 is just a improved 767, the iphone is just a improved LG Prada, the Model S is just a better Parker car from the 1800s. Yet all the above are broadly accepted as models of modern innovation.

Other supertalls built in the recent years using conventional technologies took just as long to build. The only thing that can change that picture is BSB's modular technology.
