Champlain Towers South, which was built in 1981, partially collapsed last night – and experts say it could take years to understand why.
The condo building has 136 units.
A total of 55 units were in the collapsed wing, and the building was said to be relatively full, according to the property manager.
Records show that a Notice of Commencement was filed in April to begin roofing work.
The mayor of Surfside however has said in interviews that it is unlikely the roofing work is the cause, even though that work had begun in the last 30 days.
The president of a national contractor association told the Herald that the collapse was “an oddity of biblical proportions.”
An investigation could take years, he said, and the cause could be a combination of factors.
All buildings in Miami-Dade County are required to undergo an inspection at 40 years old for structural integrity and electrical condition.
The 40 year county recertification process was just beginning to get underway, with an engineer hired to begin drawing up plans.
