Workers killed in quick-dry concrete

BAL HARBOUR, Fla. – A support frame collapsed at a high-rise construction project Saturday, killing three workers who became trapped in quick-drying concrete as co-workers dug to try to free them, authorities said.

The workers were on the 27th level of the building, pouring its concrete roof, when the supporting frame structure below them gave way, dropping them to the 26th floor, said Capt. Al Cruz of Miami-Dade Fire Rescue.

A 3-foot layer of hardening concrete completely encased one worker and partially buried the others, fire rescue officials said. The cause of the frame collapse was not immediately determined.

The identities of the three workers killed were not immediately known. A fourth worker was taken to a hospital with suspected heart trouble, authorities said.

A message left for the construction company was not immediately returned.

Police identified the building project as One Bal Harbour. It is to be a 26-story condominium with an adjoining hotel, according to the Web site for Bonita Springs-based WCI Communities Inc.

“We take great care to ensure the safety of construction crews, but at this time we have no information about what may have occurred,” the company said in a statement released to the Miami Herald.

The building had passed all inspections, said Dan Nieda of Bal Harbour’s building department.
