Death toll rises to 18, with 145 people still missing and feared trapped in the rubble a week after high-rise collapsed.
Biden, whose personal experience with tragedy has been a hallmark of his political career, will reprise the role of “consoler-in-chief” on Thursday while rescue teams continue to search for victims in the rubble of the high-rise, which caved in a week ago as residents slept.
Nobody has been pulled alive from the mounds of pulverised concrete, splintered lumber and twisted metal since the early hours of the disaster in the oceanfront town of Surfside, adjacent to Miami Beach.
Authorities have held out hope that more survivors might be found, but prospects of further rescues have grown dimmer by the hour.
Thursday’s trip marks the second time since Biden became president that he has paid a visit to the scene of a disaster.
In February, he travelled to Texas after a powerful winter storm caused serious damage to homes and businesses, left millions without power or clean water for days and killed at least 24.
Biden, who delayed his visit to Florida to avoid interrupting rescue efforts, has issued an emergency declaration and given state and local officials federal assistance to help respond to the collapse.
The Federal Emergency Management Agency (FEMA) and US Army Corps of Engineers have deployed teams to assist with search-and-rescue, incident management and debris removal.
FEMA also has coordinated with state and local officials to open a family assistance centre and provide communications support.
Biden plans to use the visit to express thanks to the “heroic first responders, search-and-rescue teams, and everyone who has been working tirelessly around the clock,” White House press secretary Jen Psaki said.
The president and first lady also will “meet with families who have been forced to endure this terrible tragedy,” Psaki added.
Biden’s gift for connecting his own hardships with the grief and anguish of others has become a defining feature of his persona. He has endured the deaths of his first wife, a daughter and a son during his years in public life.
The governor and the president spoke by telephone last week, and DeSantis praised Biden for his support after the conversation.
Investigators have not concluded what caused nearly half of the 40-year-old condo complex to crumble in one of the deadliest building collapses in US history.
But a 2018 report prepared by the engineering firm Morabito Consultants ahead of a building safety recertification process found structural deficiencies in the 12-floor, 136-unit complex that are now the focus of inquiries.
