p > In the early morning of June 24, local time, a high-rise apartment in Miami-Dade County, Florida, USA, suffered a partial collapse.

The collapsed apartment was estimated to cost 9 million U.S. dollars to repair

The residents of the “sister building” can voluntarily evacuate

After the collapse, KaVo issued an order on the 26th. All residential properties of five floors or more that are 40 years or more under the jurisdiction of the county are subject to a 30-day review. He also encouraged localities to conduct their own building reviews.

Out of prudent consideration, local officials have authorized the residents of a collapsed apartment “sister building” to be evacuated voluntarily because the structures of the two buildings are very similar. Although, Kava said on the 27th that the building inspector did not find any direct problems with the “sister building”.

On the other hand, the authorities are still investigating the cause of the collapse of the building. An engineer warned in a 2018 report that there was “significant structural damage” in the collapsed apartment building. The report pointed to waterproofing issues under the pool deck and “a large number of cracks” in the underground parking lot.

After the apartment collapsed, Surfside City, where the building was located, released a large number of documents, including previous structural field surveys, permit documents, emails, etc.

These documents include e-mails related to the 2018 cost assessment, which stated that the repair cost of the entire building will exceed 9.1 million U.S. dollars. Repairing the garage, entrance, and pool deck alone required more than $3.8 million.

A 2018 structural report by the engineering company Morabito Consultants also issued a warning that the building had “significant structural damage” and informed of the upcoming restoration project plan.

Morabito, the engineering consultant who wrote the report, said that he found that the “concrete columns, beams and walls” of the parking lot on the ground floor “have a large number of cracks and peelings of varying degrees”. Residents complained that water had entered the windows and balcony doors, and the concrete on some balconies had aged.

In addition, the company also stated that the collapsed building re-employed the company in June 2020 to begin a 40-year recertification process, which determines the work that the building needs to complete. The company’s statement added that roof repairs had begun when the collapse occurred, but concrete repairs had not yet begun.
