I understand it is much faster than the rest of the world, but my question is why 7 years? Are they simply pouring so much concrete it takes that long for it to all cure.

I mean, massive bridges and skyscrapers get built in 2-4 years, they seem to be a similar complexity.

Actually, if you're building 27 at the same time surely it's easier than building a one off massive building or bridge.
