The sinking of the skyscraper condos was caused by a combination of poor construction techniques and the soft, unstable soil on which the building was built.
It is estimated that the millionaires who invested in these sinking skyscraper condos lost millions of dollars each.
There were several warning signs, including cracks in the walls and floors, uneven settling of the building, and reports of sinking furniture and appliances.
It is possible to stabilize the building and prevent further sinking, but it would be an expensive and complicated process. It may not be worth the cost for the current owners.
Sinking buildings are not common, but they can occur if proper construction techniques and soil analysis are not conducted. It is important for developers to thoroughly research and test the site before building on it.
