No survivors have been found since the day of the collapse.
“We are working around the clock to recover victims and to bring closure to the families as fast as we possibly can,” Levine Cava told reporters earlier Thursday.
Authorities announced on Wednesday they had decided to transition from a search and rescue mission for potential survivors to an operation to recover remains.
Despite the decision, Surfside Mayor Charles Burkett said rescuers “haven’t given up all hope” and were “still praying for a miracle.”
To pay their respects to the victims, officials said search teams observed a moment of silence overnight at 1:20am (0520 GMT) -- the exact time the building collapsed two weeks ago.
Multiple investigations are under way to determine the cause of the collapse.
A 2018 report released by city officials revealed fears of “major structural damage” in the complex, from the concrete slab under the pool deck to columns and beams in the parking garage.
In a letter to residents in April, Jean Wodnicki, chair of the condo association, described “accelerating” damage to the 40-year-old building since then and repairs had been set to begin soon.
Local authorities ordered safety reviews of nearby buildings following the disaster, including Champlain Towers North, the sister tower of the condo block that fell down.
