Two cranes atop high-rise buildings under construction collapsed Sunday in downtown Miami amid strong winds from Hurricane Irma.
Hurricane Irma continues on it's path of destruction, having recently made landfall in Florida.
Only a few contractors are certified to remove those cranes, and they would not have had enough time to move them out of harm's way even if they all were working at the same time in Miami to prepare for Irma, he said.
Vice Chairman of Coastal Construction Dan Whiteman said he has 12 cranes in the Miami area, which are created to spin like weather vanes to ensure stability, according to an Associated Press report.
"It takes five to six days per crane, and they can be up to 900 feet tall and include 10,000-pound counterweights", WLRN reports.
David asked Schofer how safe high-rise buildings might be from Irma.
"AVOID THE AREA!" the city's tweet said.
"We're telling people that if you live by a construction site you should evacuate", said Alyce Robertson, executive director of the Miami Downtown Development Authority.More news: Romelu Lukaku issues warning to Zlatan Ibrahimovic ahead of his United return

The boom of the crane snapped off and is now still connected to the tower, but is hanging off the side of the building.
Whiteman said videos of the first collapse posted on social media showed a tower crane that appeared to have lost its jib or boom, though its mast was still standing.
"The luffing crane can not rotate like a weather vane", Whiteman said.
The horizontal arms of some cranes were left loose to spin in the winds.
The tower cranes are "designed to withstand winds up to 145 miles per hour, not a Category 5 Hurricane", the city said in a news release this week.
The major exception, Whiteman said, is if a tornado forms, which "virtually nothing" would be able to withstand.
"This is a life-threatening situation", the National Hurricane Center said.
