After two steel beams buckled at a Manhattan high-rise last month, city officials conducted inspections at dozens of construction sites across the city. None of the violations posed a danger to the public, the city said.
For nearly three weeks, restaurants and other small businesses in the shadow of the former Pfizer building were shut when the tower began to buckle.
Drawings obtained by The New York Times show the columns called for additional steel plates, but engineers reviewing site photos said they appeared to be missing.
A New York Times review of city records shows that the firm, Domani Inspection Services, was repeatedly accused of breaking New York City rules.
Several Manhattan buildings were evacuated Tuesday morning after construction workers discovered the structure of an office building was compromised, officials said.
The complex, which once housed offices for the pharmaceutical company Pfizer, is being converted to residences. Officials inspecting it found support columns were buckling, and upper floors were sagging.
