The narrow former parking lot, was approved for construction of a new four-story building in January.

Family and a construction worker react at the scene of deadly building collapse.

A building under construction on East 208th Street collapsed in the Bronx on August 27, 2019.

One worker was killed and five others injured — two of them seriously — when the third floor of an under-construction Bronx building collapsed Tuesday, according to authorities.

It took firefighters about an hour to dig out doomed worker — identified by relatives as Segundo Huerta — at 94 E. 208th St., where a four-story, eight-apartment building was being built at the site of a former parking lot, officials said.

“It appears they were working on the second floor… and they were trapped from the third floor to the second floor,” FDNY Chief of Special Operations John Esposito said at the scene.

“The firefighters had to put up ladders and access the second floor,” he continued. “There was a lot of rubble, a lot of broken concrete blocks, a log of the building material that covered the area, we had to dig through it.”

Department of Buildings inspectors, who remained at the site into the night, halted work there and launched a more thorough investigation.

Huerta, 48, was a native of Ecuador who has lived in the US 19 years and worked for Pioneer General Construction Co. for at least 15 years.

“I already miss my brother,” sibling Jose Huerta said Tuesday, adding that the siblings’ nephew and cousin were also working in the building.

“He was on the second floor and he was taking material up to the third floor,” Jose said of his brother. “He said the material was too heavy and that’s when the floor collapsed.”

Pioneer did not return calls seeking comment.

The DOB said there had been no violations reported at the site since work permits were issued in May.

Esposito said the two seriously injured workers were transported to local hospitals. No information was available on their injuries or their conditions.

Three other workers suffered minor injuries and were able to walk away.

Firefighters had secured the site by 1:20 p.m.

Abazi Okoro of Linzi Contracting Service, who is listed as head of construction for the project, declined to comment when reached Tuesday by The Post.
