A 25-year-old construction worker plunged nine floors to his death on Monday at an East Side high-rise, police said.

Kevin Kelly of Queens was killed when the metal ring holding his safety harness to the building pulled away from a concrete ceiling of the condo rising at 400 E. 67th St., officials said.

Kelly, who plummeted from the 23rd floor to the 14th, is the 13th construction worker killed on the job in the city this year, Buildings Department records show.

He worked for New York Window, a subcontractor of Hunter Roberts Construction Group, installing window panels at the luxury building, according to the Buildings Department.

“I was proud of him,” his father, retired construction worker Richard Kelly, said outside the family’s Bayside home. “He was a great ironworker.”

“This shouldn’t happen,” said the dead worker’s cousin Anthony Natale, 41. “We want a comprehensive investigation.”

The metal ring to which Kelly’s safety strap was attached was lying next to the body, Natale said.

Kelly, unmarried and with no children, had worked in construction for about three years, his family said. He is survived by two older sisters and a younger brother.

The owner of New York Windows, Anthony D’Amato, who was on the same floor as Kelly, collapsed with chest pains and was rushed to New York-Presbyterian Hospital Weill Cornell. His condition was not life-threatening, company lawyer Salvatore Strazzullo said.

The site has 38 open Buildings Department violations, 25 since construction began in April 2007, records show. They include such high-severity problems as failure to safeguard the public and property, lack of a site safety manager, no safety nets and lack of fire-safety standpipes, records show.

A site inspection – triggered by the March 15 crane collapse at East 51st St. that killed seven people – found there was no plumb and torque inspection report to ensure the crane there had been properly installed.

The condo, the Laurel, is next to Public School 168 on 67th St. between First and York Aves. Children were playing in the schoolyard when Kelly fell.

The tragedy comes amid a 12% jump in high-rise development and an 83% spike in construction accidents.

“You had a site known to be dangerous,” said Councilwoman Jessica Lappin, whose district includes the site of yesterday’s tragedy and the E. 51st St. disaster. “How do you allow business to carry on as usual?”

The city and the feds are investigating the accident.

Prices at the 30-story condo are expected to be $700,000 for a studio to $16 million for a penthouse. The Laurel was due to open late this year.
