DORAL, Fla. -- (NBC Miami) One person was killed in the collapse of a section of a parking garage at Miami-Dade Community College's west campus in Doral, and one other person remains trapped but located, Miami-Dade Fire Rescue said Wednesday.

Fire Rescue had specialized units and crews to dig through the debris to get the person out, who was communicating with authorities using their cellphones.

A portion of the five-story parking garage collapsed around 11:40 a.m. The garage is located at 3800 NW 115th Avenue.

Four people were treated and transported to Kendall Medical Center, while three people were treated at the scene and released, Fire Rescue said.

Police said it appeared as if the garage was occupied by construction workers only.

No students were in danger, said college spokesman Juan Mendieta. He added that it was a garage under construction. The college is closed until further notice.

One construction worker told NBC 6 that he was on the sixth floor during the collapse and he started running. He described the floors as pancakes stacked on top of each other.

The debris was about 20 feet high and a crane and heavy truck were inside the work area when the garage collapsed. Street around the garage were completely blocked off.

Aerial footage showed firefighters escorted a man, who appeared to be a construction worker, out of the garage. While firefighters apparently searched through the debris.

Victoria Buczynski of Miami said she saw the collapse while she was working at Gurkha Cigars directly across the street from the construction site.

"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."

The construction of the garage appeared to be nearly complete.

The identity of the worker who died was not immediately released.

No other information was immediately known.
