4 CANADIANS AMONG THOSE WHO OWNED PROPERTY IN THE FLORIDA CONDO AND AMONGST THE 159 BEING SEARCHED FOR........FIREFIGHTERS ON SCENE STILL FIGHTING BLAZE IN THE RUBBLE AS THEY LOOK FOR SURVIVORS......Engineers Found Florida Condo Had 'Major Structural Damage' Before It Collapsed......A structural engineering report provided to the Champlain Towers condominium association in 2018 found widespread problems that required extensive repairs "in the near future."

Parts of Champlain Towers South, a 12-story condominium in Surfside, Fla., collapsed early Thursday morning. Four people are confirmed dead and 159 others are missing. Rescue crews continue to comb through the rubble...Surfside Mayor Charles Burkett told NPR's Weekend Edition that the engineer report was likely not read until years later.

"I'm under the impression that it is something that nobody had seen until yesterday when we started looking back into the records to try to understand if there was anything in the record that would indicate why this building fell down," he said.

"We did not know about this report," Miami-Dade County Mayor Daniella Levine Cava told reporters Saturday morning. "We are obviously very interested in all of the evidence that's coming to light."

Surfside mayor worries a second building may need to be evacuated

Burkett said he's "concerned" about "an identical building built by the same builder, maybe with the same materials, maybe with the same plans, just one building away."

Town officials are considering "potentially evacuating that building so we can get in there and do a forensic investigation on the status of that particular structure," Burkett said.
