From the NY Post:
Two construction workers were killed today in a five-story fall at an Upper West Side building site, authorities said.
The men, who were not wearing harnesses, were seven stories up in the project at 150 West 83rd St. when the beam they were working on gave way around 10:35 a.m., authorities said.
They fell five stories down an under-construction elevator shaft.
EMTs struggled to revive both men at the scene before they were rushed to separate hospitals.
"In the process of the EMTs trying to revive him [one worker], they said he was having a heart attack," said witness Anthony Alvarado, 24.
"The other guy was on a stretcher, and you couldn’t tell if he was alive or not."
A 49-year-old worker was declared dead at Roosevelt Hospital, and a 51-year-old worker was declared dead at St. Luke’s Hospital.
Police and the Department of Buildings are investigating.
