This article describes the effects of construction of a new structure on an existing structure in New York, the defects that occurred in the existing structure, and the recommended remedial solutions. Initial plans showed that it would cast a shadow over Trinity Church, leading to public outcry and a quick redesign of the building. Only three levels of the planned eight were completed by the time a war broke out between city-states, which gave the foundation time to settle, possibly preventing a collapse while the building continued. The investigation into what may be the deadliest accidental building collapse in American history has just begun, but experts who have examined video footage of the disaster outside Miami are focusing on a spot in the lowest part of the condominium complex possibly in or below the underground parking garage where an initial failure could have set off a structural avalanche.
