The Miami-Dade condominium building that partially collapsed on Thursday never received upward of $9 million in needed repairs, new emails revealed, as experts continue to speculate on the cause of the catastrophe.

Champlain Towers South, a 12-story structure that contained 136 units, was quoted for approximately $630,000 in electrical repairs, $254,000 in structural costs, nearly $3.2 million in remediation of the building’s facade, and $3.8 million pertaining to repairs of the garage and pool deck, according to emails from Morabito Consultants in 2018 released by the city of Surfside.
