14. The Harbour Cay Condominium, Cocoa Beach, Florida, USA
Built: 1980-1981
Collapsed: 1981
Est. Damages: Unknown
On March 27, 1981, the Framework of Cocoa Beach, Florida’s, newest 5-story residential development project, known as The Harbor Cay Condominium, was nearly complete. Workers were in the process of pouring the roof’s concrete when everything came crashing down. The building collapsed as a result of multiple errors, most notably, the thickness of the building’s concrete slabs was one-third of a size too thin.

Unlike the Champlain Towers of Surfside, Florida, since the Harbour Cay Condominium was still under construction, when it met its untimely fate, there were no residents inside. 11 construction workers lost their lives in the collapse, and another 27 sustained non-fatal injuries.
