At least 11 people have died and 150 remain unaccounted for. A county-wide building audit has already uncovered issues as officials seek answers.

CNN reached out to Fernandez Rundle’s office, who said a statement is forthcoming. “We were talking about whenever it is moving forward, that we will be fully on board,” Levine Cava said.

Rescuers will continue to consider the unaccounted-for as “missing until they are found,” Florida Gov. Ron DeSantis said in a news conference late Tuesday morning.

“Nobody is giving up hope here. Nobody is stopping,” Surfiside Mayor Charles Burkett said at the same news conference.

Still, officials acknowledged that conditions at the site are challenging for emergency workers. Burkett told CNN’s John Berman earlier on Tuesday that debris had fallen overnight Monday into Tuesday from portions of the building that remain standing.

Additionally, workers are steering clear of a “45-foot area next to the building” because of concerns about overhanging debris from the standing portion, Miami-Dade Fire Chief Alan Cominsky said Tuesday.

More than 3 million pounds of concrete have been removed during the rescue operation, Cominsky said.

People join together in a community twilight vigil on the beach for those lost and missing during the partially collapsed Champlain Towers South condo building Monday.

April 2021 letter said damage ‘has gotten significantly worse’

“The concrete deterioration is accelerating. The roof situation got much worse, so extensive roof repairs had to be incorporated,” the letter from board President Jean Wodnicki reads.

Wodnicki further described issues facing the building: “When you can visually see the concrete spalling (cracking), that means that the rebar holding it together is rusting and deteriorating beneath the surface.”

CNN has reached out to representatives of the condominium association for further comment.

Building residents also had raised concerns over tremors during construction of a nearby building in 2019, according to documents obtained by CNN and interviews with the family members of people missing in the collapse.

“We have months and years to dig into what happened, and we’re going to. The board is already in the process of hiring an engineer to also try to figure out what happened, and they will be evaluating who’s responsible.”

New class action lawsuit filed

The lawsuit was filed on Monday on behalf of Raysa Rodriguez, a resident who lives on the ninth floor of the building, as well as other residents.

The suit states the condominium association had the duty to maintain the building in a safe condition and good working order.

“Despite the obvious duties required by Florida law, and this admitted duty of care by the Association’s Declaration and other governing documents, Defendant, through their own reckless and negligent conduct, caused a catastrophic deadly collapse of Champlain Towers South in Surfside,” the complaint alleges.

In filing the complaint, Rodriguez is seeking class action status to represent all of the people who were affected by the tragedy, and is asking the court to help preserve any materials so everyone who is to blame can be held responsible.

CNN’s calls to the Champlain Towers South Condominium Association seeking comment on the lawsuit have not been returned.

Mayor: County building audit already has uncovered serious issues

Because of the collapse, a building audit is underway across the county, and that audit has already uncovered serious issues, said Mayor Levine Cava.

“Just last night, our building officer notified one of those properties, a building in northeast Dade, that four balconies must be immediately closed to residents due to safety conditions,” Levine Cava said at Tuesday morning’s news conference.

“We’re taking swift action to immediately identify and address any outstanding issues with the buildings that have not yet completed their 40-year certification process — that’s our priority right now,” she said.

Levine Cava says she expects all issues the audit turns up will be addressed in a matter of weeks.

Families and friends are waiting for answers

The 11 known to have died have been publicly identified. They were Stacie Fang, 54, Antonio Lozano, 82, Gladys Lozano, 80, Manuel LaFont, 54, Leon Oliwkowicz, 80, Luis Bermudez, 26, Anna Ortiz, 46, Christina Beatriz Elvira, 74, Marcus Joseph Guara, 52, Frank Kleiman, 55 and Michael David Altman, 50.

Family members of those still unaccounted for are waiting for any answers they can get as the search continues.

A person adds flowers Monday to a memorial that has pictures of some of the missing from the partially collapsed Champlain Towers South condo building in Surfside.

“And she told me, ‘I can go get her. … I know where she hides. I’m really good at finding her,'” Rachel Spiegel told CNN on Tuesday morning. “When she’s telling me that, I’m … crying even more, but at the same time trying to keep my composure because I don’t want my 4-year-old to worry too much.”

“I hope my mom is alive … but we also are very aware of the reality of the situation and the time — I mean, it’s Day 6. And the fact that they aren’t finding people is of tremendous concern,” Rachel Spiegel said.

Ronit Felszer and Carlos Naibryf told CNN’s Alisyn Camerota on Monday that they are being realistic about the possible outcome.

Carlos Naibryf said his son, Ilan Naibryf, “was a 21-year-old young adult. Bright. Everywhere he went, he made an impact … now he’s at U. Chicago, physics major.”

When Camerota asked the parents if they’re sill believing in a miracle, Felszer shook her head. “We want to believe in a miracle because we still don’t have the physical presence, in part or in whole, of our son,” she said.

“A miracle can come, yes, but we have to be very realistic,” the father told CNN.
