Tunnelling rescuers search for survivors in Florida condo collapse | CBC News

Families of the missing rode buses to a site nearby from which they could watch teams at work Sunday: firefighters, sniffer dogs and search experts employing radar and sonar devices.

Andy Alvarez, a deputy incident commander with Miami-Dade Fire Rescue, told ABC’s Good Morning America on Monday that rescuers have been able to find some voids inside the wreckage, mostly in the basement and parking garage areas.

“We have over 80 rescuers at a time that are breaching the walls that collapsed, in a frantic effort to try to rescue those that are still viable and to get to those voids that we typically know exist in these buildings,” Alvarez said.

“We have been able to tunnel through the building,” Alvarez added, and big cranes have helped rescuers lift “huge pieces of concrete” off the pile. “This is a frantic search to seek that hope, that miracle, to see who we can bring out of this building alive,” Alvarez said.

He said rescuers, like the families, are still hoping for good news. “You’ve gotta have hope and you’ve gotta have faith,” he said.

WATCH | Desperate search continues at collapsed Miami-area condo building: 

Nine people are confirmed dead and more than 150 are still unaccounted for after a condo building collapsed outside Miami, while the search for survivors continues and more is learned about the building’s history. 2:59

Israeli Diaspora Affairs Minister Nachman Shai, head of a humanitarian delegation from Israel that includes several search-and-rescue experts, said the professionals have told him of cases where survivors were found after 100 hours or more.

“So don’t lose hope, that’s what I would say,” he said.

Some families had hoped their visit to the site near the 12-storey building would allow them to shout messages to loved ones possibly buried deep inside the pile. As they returned to a nearby hotel, several paused to embrace as they got off the bus. Others walked slowly with arms around each other back to the hotel entrance.

“We are just waiting for answers. That’s what we want,” said Dianne Ohayon, whose parents, Myriam and Arnie Notkin, were in the building. “It’s hard to go through these long days and we haven’t gotten any answers yet.”

Deadline for repair payments

The building collapsed just days before a deadline for condo owners to start making steep payments toward more than $9 million US in repairs that had been recommended nearly three years earlier, in a report that warned of “major structural damage.”

Authorities on Sunday identified the additional four people whose remains had been recovered as Leon Oliwkowicz, 80; Christina Beatriz Elvira, 74; Ana Ortiz, 46; and Luis Bermudez, 26. The number of people left unaccounted for was 152, said Miami-Dade Mayor Daniella Levine Cava. The last person to be rescued alive was found on Thursday, just hours after the collapse.

Miami-Dade Assistant Fire Chief Raide Jadallah explained that conditions at the site — the building pancaked when it fell — have frustrated crews looking for survivors. Alan Cominsky, chief of the Miami-Dade Fire Rescue Department, said his team is holding out hope of finding someone alive, but must continue to move slowly and methodically.

“The debris field is scattered throughout, and it’s compact, extremely compact,” he said, noting that teams must stabilize and shore up debris as they go.

“We can’t just go in and move things erratically, because that’s going to have the worst outcome possible,” he said.

Radar tool

Among the tools rescuers used was a microwave radar device developed by NASA’s Jet Propulsion Lab and the Department of Homeland Security that “sees” through up to 20 centimetres of solid concrete, according to Adrian Garulay, CEO of Spec Ops Group, which sells them. The suitcase-size device can detect human respiration and heartbeats and was being deployed Sunday by a seven-member search-and-rescue team from Mexico’s Jewish community.

Levine Cava said six to eight teams are actively searching the pile at any given time, with hundreds of team members on standby ready to rotate in. She said teams have worked around the clock since Thursday, and there was no lack of personnel.

U.S. President Joe Biden said in a statement he spoke with FEMA Administrator Deanne Criswell about efforts on the ground after Criswell visited the site. Biden said his administration is prepared to provide assistance and support.

“This is an unimaginably difficult time for the families enduring this tragedy,” Biden said. “My heart goes out to every single person suffering during this awful moment.”

WATCH | Death toll in Florida building collapse rises to at least 9: 

The death toll after the collapse of a 12-storey condo building in south Florida rose to at least nine people on Sunday, with dozens still missing, officials said. 4:14

Crews spent Saturday night digging a trench that stretches 38 metres long, six metres across and 12 metres deep, which allowed teams to find more bodies and human remains.

Earl Tilton, who runs a search-and-rescue consulting firm in North Carolina, said rushing into the rubble without careful planning and execution would injure or kill rescuers and the people they are trying to save.

“Moving the wrong piece of debris at the wrong time could cause it to fall” on workers and crush them, he said.

But Tilton agreed families were not wrong to continue holding out hope. During past urban rescues, he said, rescuers have found survivors as long as a week past the initial catastrophe.
