CLEVELAND, Ohio -- The Occupational Safety and Health Administration determined a construction company overloaded a crane last year in Cleveland’s Playhouse Square before steel beams fell onto the top of a parking garage.

The federal agency cited Donley’s Inc. for three “serious” violations related to the Oct. 10 accident at the construction site for The Lumen, a 34-story residential tower on East 14th Street near Euclid Avenue, according to a letter dated Jan. 9.

No one was harmed during the incident.

OSHA has proposed Donley’s pay a $39,780 fine for the violations, according to the letter.

Donley’s said in a statement Thursday that it is reviewing the findings, and plans to request an informal conference to discuss them. The company has 15 days to request a conference, OSHA said in its letter.

“Safety is our number one priority at Donley’s. It is at the core of all of our values,” the company said in its statement.

OSHA determined the lead contractor on the project, Rhode Island-based Gilbane Building Co., did not commit any violations. Gilbane hired Donley’s as a subcontractor to perform masonry and carpentry, OSHA said.

OSHA defines serious violations as “incidents where there is substantial probability that death or serious physical harm could result and that the employer knew, or should have known, of the hazard.”

The violations include overloading the rigging equipment; failing to ensure the nylon straps used to lift the steel beams were in good condition; and failing to ensure no one was working underneath the steel beams when they were loaded on the crane.

Several steel beams fell from the crane onto the parking garage, causing part of it to collapse. One of the beams pierced through concrete.

Donley’s is headquartered in Cleveland but also has locations in North Carolina, South Carolina and Virginia, according to its website.
