The Federal Emergency Management Agency on Friday showed off its new emergency hospital for coronavirus patients at the Javits Center.

Four sections of the exhibition space on Manhattan’s West Side have been converted into 1,000 individual, prefabricated treatment rooms that were assembled by 320 workers over the past week, officials said.

The makeshift hospital, dubbed the “Javits Center Medical Station” by FEMA, is set to open on Monday.

Each room is outfitted with a bed, lamp, night table and humidifier to ease the breathing of patients suffering from the deadly respiratory disease.

There’s hand sanitizer — made by state prison inmates — on the night table, and each room is also equipped with a red backpack that holds an N95 respirator and more hand sanitizer for use once the patients are discharged.

Gov. Andrew Cuomo called the work “transformative.”

“In just one week, the Javits Center looks entirely different, changing its ability to save lives,” he said during a news conference.

Journalists were later given a sneak peek of the rows of rooms set up in the 40,000-square-foot 3E Hall.

The general contractor for the job, T3 Expo, set up last month’s Toy Fair at the Javits Center and was approached last week to build the FEMA hospital.

Once the materials arrived Wednesday, the first 500 rooms went up in just a day and a half, said Tim Heffernan, the company’s chief development officer.

“There was a lot of moving parts and a lot of agencies that came together pretty quickly,” he said.

“I was surprised at how smooth it went — concept to execution in four days.”

The emergency hospital is one of four that President Trump has instructed FEMA to build and run in the New York City area.

Cuomo said Friday he’d be asking Trump to authorize four more, so there’s one in each of the five boroughs, as well as Nassau, Suffolk and Westchester counties.
