A 2010 repair plan for the parking garage that collapsed Tuesday shows that the 115-year-old building was in rough shape.

“Most of the repairs that the engineer was suggesting was occurring at the roof level,” Richard Lambeck, chair of the construction management department at the NYU Schack Institute of Real Estate, said.

Lambeck reviewed the engineer’s plan for NY1.

The parking garage had been hit with violations for hazardous conditions in 2003 and 2009, citing cracks and defects in the concrete.

What You Need To Know

  • The parking garage had been hit with violations for hazardous conditions in 2003 and 2009, citing cracks and defects in the concrete

  • The Department of Buildings ordered the owner to hire an engineer to make a repair plan fixing the hazardous conditions

  • The violations remain open because the Department of Buildings never received certification that the hazardous conditions were fixed by the repair

Later, the Department of Buildings ordered the owner to hire an engineer to make structural repairs and install 34 auto lifts.

“Department of Buildings visited the site and observed that repairs were in progress,” Kazimir Vilenchik, acting commissioner of the Department of Buildings, said Friday.That was in 2011.

“They are concerned about the structural integrity of those beams,” Lambeck said. “It shows that the structural capability of those beams were no longer capable of taking the weight that it was originally designed for.”

The report also details cracks in the concrete as long as 11 feet — but Lambeck said there’s nothing indicating the width of the cracks, and that they could have been hairline fractures that had no bearing on stability.

Officials are looking at the age of the building and the weight of the cars on its roof.

The structure — three stories with an underground cellar — has been a garage since 1926.

That means decades of cars dragging snow and salt into the garage and onto its roof.

“Salt has a deteriorating effect not only on the concrete, but on the steel, not only the reinforcing steel, but the structural steel, that really supports the structural members of the roof plan,” Lambeck said.

It’s unclear to what extent the repairs were made.

The Department of Buildings says that follow-up inspections did not result in violations for structural concrete issues.

But department officials say the owners never certified to the agency that the violations were fixed by the repair work, which is why the violations remain open today.
