19 days to -assemble- a 57 storey tower. Four and a half months constructing the modules for assembly.

> Broad Sustainable Building spent four and a half months fabricating the building’s 2,736 modules before construction began. The first 20 floors were completed last year, and the remaining 37 were built from 31 January to 17 February this year, Xiao said.

Early on in the article I wondered about how steel was going to be CO2-efficient, given the amount of coal involved in its production; but then I see it's as a replacement for concrete, which is much worse.

Sometimes I think IT industry is moving slow, because it's so much harder to multiply the efforts with more human power. IT is so much quality over quantity that effects like this would not happen easily. Although there is no mention of the planning involved in the construction of the building, I think the result is astonishing.

Considering this is prefabricated module assembly it is exactly like today's development work.

Even more so as people have created frameworks and libraries that you can use freely to compose your application in much less time than if you had to do it all over again.

Some of these frameworks and libraries simplify the process so much that you CAN throw more human power at it and still get good results.

Still amazing if you ask me...

Steel fabrication does not necessarily require coking coal.

As a one off cost, for a building that stands for so long and house that many, is it really a relevant question, compared to what the house and its inhabitants will use during its lifetime?

It's not like conventional construction doesn't use parts that need more time to be pre assembled.

The Soviets built these type of buildings at the same speed in the 60s: http://en.wikipedia.org/wiki/Panel%C3%A1k Amazing, doing it higher than 20 floors though.

These paneláky were built at some scale in Czech Republic too. They're a little grim normally, but quite a lot get painted in nice pastel colours so many look quite pretty sometimes. I stayed in one in Brno for a while, the walls are paper thin so I had a very ... intimate knowledge of what my neighbours were up to (our bedrooms were adjacent, as were the bathrooms) and vice versa :)
