SURFSIDE, Fla. (AP) – The collapsed oceanfront condominium building near Miami suffered “major structural damage” to a concrete structural slab under its pool deck that needed extensive repair, according to a 2018 engineering report on the building.
The report was part of a series of documents released by the town of Surfside as rescuers continued to dig through the rubble of the building on Saturday in an attempt to find one of 159 people missing after it collapsed.
At least four people were killed.
Although the Morabito Consultants engineering report did not warn of imminent danger of damage – and it is not clear whether any of the damage observed was responsible for the collapse – it noted the need for major and expensive repairs to fix the system problems with the building.
He said the waterproofing under the pool deck failed and was improperly laid flat instead of tilted, preventing water from draining.
“Failed waterproofing is causing major structural damage to the concrete slab below these areas. Failure to replace waterproofing in the near future will cause the extent of concrete deterioration to expand exponentially, ”the report said. The company recommended that damaged slabs be replaced in what would be a major repair.
The report also found “extensive cracks and crumbling” of concrete columns, beams and walls in the parking garage. Some of the damage was minor, while other columns had exposed and deteriorating rebar.
He also noted that many of the building’s previous attempts to repair columns and other damage with epoxy had been marred by poor workmanship and were unsuccessful.
Under the pool deck “where the slab had been epoxy injected, new cracks radiated from the originally repaired cracks,” the report said.
On Friday, at the site where the building was located, dozens of rescuers used large machines, small buckets, drones, microphones and their own hands to pick up the mountain of debris that had made up the 12 floors of the Champlain Sud towers. .
Rachel Spiegel was eager to hear about her missing mother, Judy Spiegel, 66, who lived on the sixth floor. “I’m just praying for a miracle,” Spiegel said. “We are heartbroken that she is even in the building.”
Jeanne Ugarte faced what she feared would be a tragic end for her longtime friends Juan and Ana Mora and their son Juan Jr., who was visiting his parents in their tower block condo.
“I know they’re not going to find them (alive),” Ugarte said. “It’s been too long.”
Hopes rested on how quickly the crews could complete their dark but delicate task at Surfside, a few miles north of South Beach in Miami.
“Whenever we hear a sound, we are focusing in that area,” said Miami-Dade Deputy Fire Chief Raide Jadallah. “It could be just a twist of steel, it could be debris raining down, but not specifically tapping sounds or the sounds of a human voice.”
Shaken by gusts of wind and bombarded by intermittent rains, two heavy cranes removed debris from the pile using large claws on Friday, creating a din of glass and metal crashing down as they scooped up materials and threw them aside. A haze of smoke rose from the site.
After the machines had stopped, firefighters wearing face masks and carrying red buckets climbed onto the job to remove small pieces by hand in hopes of finding places where people could be trapped. In a parking garage, lifeguards in knee-deep water used power tools to cut through the building from below.
Surfside Mayor Charles Burkett said crews were doing everything possible to save as many people as possible. “We don’t have a resource problem, we have a luck problem,” he said.
Officials said they still did not know exactly how many residents or visitors were in the building when it fell, but they were trying to locate 159 people who were believed to be missing and who may or may not be present.
Flowers left in tribute decorated a fence near the tower, and those awaiting news of the research watched from afar, hands clasped and hugging. Worshipers prayed at a nearby synagogue where some members were among the missing.
Miami-Dade Police Director Freddy Ramirez said authorities were working with the medical examiner’s office to identify the bodies found. Eleven injured were reported, including four people treated in hospitals.
Miami-Dade Mayor Daniella Levine Cava said rescuers were at “extreme risk” of walking through the rubble.
“Debris is falling on them as they do their job,” she said. “We have structural engineers on site to make sure they don’t get injured, but they keep going because they’re so motivated. “
Teenager Jonah Handler was rescued from the rubble hours after the collapse, but his mother, Stacie Fang, has died. Relatives issued a statement expressing their thanks “for the outpouring of sympathy, compassion and support we have received.”
“There are no words to describe the tragic loss of our beloved Stacie,” he said.
While officials said no cause for the collapse as of Thursday morning had been determined, Gov. Ron DeSantis said a “definitive response” was needed in a timely manner. The video showed the center of the building appearing to collapse first, followed by a section closer to the beach.
