CINCINNATI (AP) — A company whose workers were hurt when a floor collapsed at an Ohio casino construction site says it’s ready to resume work when investigators decide it’s safe.

More than a dozen people were hurt Friday morning at the Horseshoe Casino Cincinnati site, where they were pouring a section of concrete floor. Most were treated for bumps and scrapes and released.

The president of Cincinnati-based Jostin Construction says four employees suffered orthopedic injuries. Three needed surgery.

A hospital spokesman says one injured man remained hospitalized in serious condition Sunday.

Jostin Construction says it’s cooperating with officials investigating what caused the collapse.

The collapse occurred weeks after a similar accident at a Cleveland casino with the same developers. The developers have said there’s no link between the two cases.
