DELTONA, Fla. -

One of several survivors in this week's deadly garage collapse in South Florida has been identified as a Volusia County man.

Mark DiBacco, 48, of Deltona, suffered a broken ankle in the collapse of the five-story structure, which occurred Wednesday at Miami Dade College's west campus.

DiBacco told Local 6 News that he heard a loud boom as he was getting tools from his truck on the bottom floor of the garage and a "waterfall (of concrete) came rushing toward me."

"I didn't think that I was going to make it.  Thank God it stopped like 20 feet before it hit me or I wouldn't have made it.  It's unreal," said DiBacco, who added that he won't be able to work for six to eight weeks.

Authorities have said at least seven people who were hurt either worked for Ajax Building Corp. or a subcontractor hired to construct the garage.

Meanwhile, crews continue searching through piles of twisted steel and concrete for a missing worker.  The missing man's family huddled nearby Thursday as police told them it could take days to find someone in the debris.

Two workers pulled from the rubble died at a Miami hospital on Wednesday. Another man was rescued 13 hours after the collapse, but died a short time later at the hospital.

"My heart goes out to the families that lost their loved ones.  I'm just happy to be home with my family," DiBacco said.
