3 stories a day, but a one year delay between levels 20 and 21!!!

The completion rate doesn't sound quite as good when it's 57 stories in 384 days...

Really? I missed that.

I really must stick to submitting when I'm at work and don't have a screaming four year old in my ear

And will it withstand an earthquake in 20 years?

So I guess what we're seeing is they constructed the metal/concrete framework at 3 stories a day but from the comments it took a year to add internal walls, external cladding, glass, power, gas, water etc etc.

Making a framework in 19 days is less impressive then making a functional building - but this still seems fast.

The extra one year delay was for legal reasons, not to do with construction. It's from the postscript near the end of the vid.

The construction really was impressive, I was just nitpicking.

"Constructed" may also be a misnomer..., The way I see it, it may have been "Assembled" in 19 days, but the building had to start long before that, as construction began off-site with all the panels and parts being engineered so that they could be assembled on-site.

No mention of the length of time for that process.
Pretty sure everything wasn't manufactured on site.
I see a very large meccano/lego set being assembled.

Prefabricated construction has a long history both in China and the west, and to some degree almost every modern building uses the technique. There is a video on here about the construction of the Empire State building for instance, and the WTC twin towers were quite prefabricated too.

It was particularly popular in ancient Rome, and combined with the use of cranes and concrete their construction times weren't that different to the modern era (actually sometimes faster, I think the planning process must have been more streamlined).

The standardised look of ancient Chinese buildings is for the same reason, the parts were standardised to make prefabrication easier, certainly by the Ming dynasty if not earlier - see http://whc.unesco.org/en/list/705 for instance.

This particular building just does a particularly good job of it.
