The Harbour Cay Condominium was a five-story flat plate residential development project in Cocoa Beach (Brevard County, Florida, United States) that collapsed during construction on March 27, 1981.

[2] The building, being constructed by the Univel Corporation of Cocoa Beach, collapsed as workers were completing its framework by pouring concrete for the roof.

Thus, punching shear failure at one of the columns precipitated a progressive failure of the slab throughout the entire fifth floor.” Two engineers, an architect, and two contractors were charged with negligence, misconduct and failing to conform to state and local building laws.

[4] According to Mike Thomas of the Orlando Sentinel on April 20, 1997, the local contractor, Univel, folded almost immediately.

The senior developer, and the real money behind the project, contractor Towne Realty out of Milwaukee, agreed to a settlement out of court to avoid litigation.
