After a meeting this week with inspectors, engineers and architects within the building department, they felt it was necessary to go back to the engineer on record, Oswald said.

“They won’t be able to use it until they get a design professional to verify it’s safe and that it’s done correctly and that the fix has been made,” Oswald said.

Oswald said this type of request was not uncommon but didn’t happen all the time. He would not speculate on what might have caused the flooring problems.

Barnes-Jewish Hospital board member Tom Hillman told the Post-Dispatch this week that construction issues had been brought to the board’s attention.

He said that there were a “variety of issues” but that the “most evident is the leveling.”

Rumors have been circulating for months that the floors in the building are not level. An IV pole placed on one of the floors rolled away, according to one report.

June Fowler, spokeswoman for BJC Healthcare, took issue Friday with the term “buckling” in describing the floor problems. “There is some unevenness,” she said. “There are levelness issues, and those issues are being addressed.”
