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

The workers were on the 27th story where a concrete floor was being poured when the supporting frame structure below them gave way and they fell to the 26th floor, said Capt. Al Cruz of Miami-Dade Fire Rescue.

A 3-foot layer of concrete fell onto the workers and partially buried them, said fire rescue Capt. Allen Brown.

Fellow workers tried to dig them out before rescue crews arrived.

The cause of the frame collapse was not immediately determined.

“It’s very unstable up there,” fire Capt. Al Cruz.

A fourth worker was taken to a hospital with suspected heart trouble, he said.

Identities of the dead workers were not immediately known.

The building, One Bal Harbour, is to be a combination hotel and condominium, said police Capt. Jay Smith.

Bal Harbour, just north of Miami Beach, is known for its tall hotels and high-end shopping.
