Report on collapsed Miami building warned of "abundant cracking" in its concrete

Engineers warned of "major structural damage" to the concrete of the Champlain Towers South condominium in Miami, which collapsed last week leaving 10 people dead and 150 missing.
A 2018 report on the condition of the 136-unit residential building in the town of Surfside, Florida, noted that deterioration in the concrete would "expand exponentially" unless repairs were made in a "timely fashion".
Part of the 12-storey beachfront block collapsed suddenly at 1:30 am local time on Thursday 24 June.
