Construction of buildings and skyscrapers is a job that often takes months, if not years - but not for this construction company in Changsha, China. Broad Group, a Chinese enterprise that has many verticals, one of which is sustainable development, created a splash on the internet by building a 10-storey residential building in a little over a day — 28 hours and 45 minutes, to be precise.
So, are you wondering what the secret could be to this marvellous speed of construction? It is the technology of pre-fabricated construction systems, wherein the building is constructed by means of assembling small self-contained modular units that were built in advance in a factory.
These container-sized pre-fabricated units are then taken to the building site and stacked on top of one another, bolted into place and made into a fully constructed building. Finally, power and water connections are added.
According to CNN, Broad Group was able to construct a 10-storey apartment building in 28 hours and 45 minutes in Changsha, China.
In a 4-minute, 52-second video on YouTube of the timelapse of the construction of the aforementioned building, Broad Group wrote, “Standard container size, low-cost transportation worldwide. Extremely simple onsite installation.”
In the video, the group says it was an “extremely simple onsite installation” — “just tighten bolts and connect water and electricity”.

People were amazed at the speed of the construction.
One user, Tom Ritucci, appreciated the interior design, saying the finish was “really nice!”
Another user, Hanatomy, said it was a “revolution” in making houses.
The best thing about such pre-fabricated set-ups is that the individual units can be dismantled and moved if needed. According to New Atlas, the group said its prefab setup is also very durable and earthquake-resistant
