Because of the unprecedented collapse, the government examined the safety of other buildings constructed using the same concept as the Ronan Point Tower. The rare foundation failure and collapse of the building in China was caused by excavated earth on one side and piled up earth and water table on the other side, exerting differential pressure on the piles. In 1284, part of the choir vault collapsed due to the strain and, possibly, vibrations from high speed winds. However, the proprietors later chose to advertise them as apartment suites.
