Sometimes you can see news as to China building a skyscraper in 8 days...

Can it happen in the US?

In the US there would be too much documentation and safety issues and at each stage of construction you have to wait for city inspector to inspect things for compliance and ONLY THEN you can proceed etc etc… in short, china may bypass all these but US doesn’t. That is the main reason, and not that US does not have the technology. This is also another reason why the construction projects in the US cost so much, in addition to expensive labor. So not just speed but think about cost too. And of course, never forget the quality… The usual three constraints: time, money and quality in other words.
