China has been well known for its innovation over the course of years. They have soared into new heights with haste.
With that in mind, they have accomplished something that no human being had thought that it was possible — building a skyscraper in a matter of 19 days!
Broad Sustainable Building Co. was the developer of the said 57-story Mini Sky City in the Hunan provincial capital of Changsha. With the use of modular method, they have assembled three floors per day.
Large sections of the building were prefabricated off-site, and then stacked and transported to the building site for construction.
“With the traditional method, they have to build a skyscraper brick by brick, but with our method, we just need to assemble the blocks,” company engineer Chen Xiangqian said.
According to the developer, it has reduced the number of trips needed to deliver the raw materials, thus lessening carbon footprint production.
They have also used quadruple-thick glass with a guaranteed 99.9% sealed construction.
Mini Sky City has 19 atriums and 800 apartments, with enough office space to hold 4,000 people at a time.
They have also boasted that the can withstand earthquakes.
Now, skyscrapers can be built in a short period of time in a safe and reliable way.
The only drawback to this type of construction is that the architecture will seem uniform, because some prefer to have a more personalized and elegant design.
Originally, the building was supposed to stand at 220 stories to be done in less than three months, but the plan was revised and the height was cut down due to concerns of its proximity to an airport.
The Changsa-based company spent more than four months in planning and preparation, as well as 2,736 modules, before proceeding with the construction.
For comparison, the World Trade Center would have been built in just over a month if it were constructed at the same rate.
Previously, they have built a 30-story building also in Changsa at 15-days time.
