15 days to build a 30-story building?
Quite an achievement realized by a company (“The Broad Group”) which started in the business of heating equipment and air conditioning less than 25 years ago!
There are of course important questions raised by such an engineering feat, e.g. in terms of structural resistance and scalability. One may also quibble about the fact that the conception of the design and the production of the pre-fabricated elements need to be factored into the timeline. It nonetheless strikes as a very interesting example of process innovation.
If you have 3 minutes to spare, the video is well worth watching.
