One person remains trapped inside the rubble of a Miami-Dade College parking garage that collapsed Wednesday, killing one worker and leaving several others injured.
Miami-Dade Fire Rescue Captain Louie Fernandez said the garage's structural integrity was making the rescue effort difficult, CBS Miami reported.
The trapped worker was getting oxygen and being treated by a physician, but officials did not describe the extent of his injuries. Fernandez said the rescue would be a "long, tedious effort."
At least seven other workers were hurt when the roof of the five-story concrete garage fell shortly before 11:40 a.m., creating a pancake-style collapse on the West Campus of Miami-Dade College, officials said.
Four workers were taken to the hospital, including one in serious condition, Miami-Dade Fire-Rescue spokeswoman Griselle Marino said. Three others were treated by paramedics at the scene.
Crews estimated that approximately 30 workers were in the nearly completed garage when it collapsed, according to CBS Miami.
"It was a floor upon floor, collapsing all the way down to the ground floor," Fernandez said.
Dogs, firefighters and other people in hard hats walked over piles of concrete, plywood and metal rubble to look for other possible victims, but there was no indication anyone else was missing.
Victoria Buczynski of Miami said she saw the collapse while she was working at Gurkha Cigars across the street from the construction site at Miami-Dade College.
"It fell to the ground like a house of cards," Buczynski said. "The construction workers started running out, screaming. It was loud. Our entire building shook."
No students were in the area at the time. The campus was evacuated after the collapse and closed for the rest of the week as investigators planned to pick through the rubble to see what caused the garage to crumble.
The construction of the 1,855-space garage was nearly complete. Ground was broken on the $22.5 million project in February, and it was to be finished in December, according to the website of the contractor, Ajax Building Corp.
The first floor was to have classroom and office space. The structure is nestled closely to other buildings at the college, which serves about 8,000 students and is one of several campuses in the Miami-Dade College system. This campus opened in 2006.
An Ajax spokeswoman declined comment and said a company safety crew was en route to the scene.
The identity of the worker who died was not immediately released.
Miami-Dade College director of communications Juan Mendieta called the collapse "a very tragic situation," adding, "Our thoughts are with the construction workers," CBS Miami reported.
