Rescue workers sought permission from authorities after the condominium exploded, which could provide a clear picture of the possible difference in the wreckage and where 121 people may be missing.
Rescue workers were given the green light to continue searching for landslide victims in South Florida on Sunday when demolition crews planted explosives to smash the rest of the structure.
The demolition took place around 10:30 a.m. "exactly the same plan." According to Miami-Dade Mayor Daniella Levine Cava on Sunday.
Some new debris was immediately removed so that rescuers could begin moving to areas of special interest underground parking.
Once there, they hope to get a clear picture of the wreckage in the wreckage and find out that some of the 121 people may have been trapped as a result of the June 24 collapse of the South Champlain Tower in Surfside. They will remain between the concrete blocks.
No one was rescued during the first hours after the crash. Miami-Dade County Police identified David Epstein, 58, as one of 24 documented deaths in a landslide on Sunday. His remains were found on Friday.
The proximity of Tropical Storm Elsa immediately added to demolition plans, as the forecast indicated strong winds in the area until Monday. It was feared that the collapsed structure posed a threat to rescuers and could prevent them from working in some areas. The rest of the building was evacuated on Thursday, forcing a 15-hour suspension.
The missing include dozens of Latin Americans from Argentina, Colombia, Chile, Paraguay, and Uruguay.
Levine noted that the search operation was "necessary to expand" in a controlled manner, as teams were unable to search further due to the risk of a crash.
State officials said they hired BG Group, a Delray Beach, Florida-based general contractor, to lead the demolition. No details were known about how the company was selected, but a contract for the project calls for the state to pay the company $ 935,000.
According to experts, a spokesman for the Emergency Management Division said the company subcontracted Controlled Demolition Inc . based in Maryland, which, according to experts, is one of the few companies in the United States that demolishes structures with explosives. According to the contract for the work, the company was required to place explosives on the basement and lobby levels of the system.
CDI is "probably one of the best" in the industry, said Steve Schwartz, a board of directors of the National Demolition Association. He described the president and owner of the company, Mark Loizeaux, as "cold, calm and collected."
In implosions - the use of explosives to cause a building to fall on itself - charges are typically activated in rapid succession in a matter of seconds, said Scott Homrich. He heads the National Demolition Association and has his own demolition company in Detroit. , Michigan. The activation of the explosives at intervals serves to break the building as it collapses.
Some residents had begged to go home one last time before the demolition to retrieve belongings they had left in a hurry but were denied. Others wondered about the pets left behind, although officials said they had found no signs of animals after making three final sweeps, including using drones to spy on the abandoned structure.
Officers have been discussing their decisions with survivors since search and rescue efforts began, Levine Cava said.
We understand that families realize the fact that time has passed; they realize that the possibilities are getting smaller and smaller, " he said in "Today." "They are with us; they know what we have been doing at all times."
The mayor also said teams are working to save as many personal items as they can. "We have asked them to go cataloging all their precious belongings so that, as soon as they are recovered, we can make a comparison."
President Joe Biden visited the site Thursday and met with the families of the victims, who erected a memorial on metal nets covered with pictures of the dead and missing and decorated with flowers and candles.
Although the building was presumed to have failed to be maintained, there is still no clear answer as to the cause of the collapse.
We don't have solid evidence of what happened," Biden said Thursday, noting that there are "several questions." He mentioned the maintenance and structure of the building, nearby construction sites, and rising waters.
A 2018 report released by city officials raised fears of "major structural damage" to the complex, from concrete slabs under the pool deck to columns and beams in the parking lot.
