Broad Sustainable Building, a construction company based in Changsha, China, completed 57 storey skyscraper by making pieces of the structure and then building it at the location in just 19 days.
This building was built at a rate of 3 stories per day to make this record.
After constructing 20 stories, the tower was stopped due to the height restriction in the 9.5km of the airport. The construction resumed after the 97-storey building was lowered to 57 floors.
