The opening of the new Katy City Hall has been delayed after construction materials and interior doors were unable to be delivered on time, officials said. “We’re not going to make that April 22 open house,” said City Administrator Byron Hebert. “It’s a small delay. We don’t have an exact [opening] date yet.” Hebert said materials for the building’s roof as well as multiple interior fireproof doors are unavailable for delivery due to being on back order. “We’ve got some delayed products,” he said. “If you have a life-safety issue, you can’t proceed. We’re going to make it perfect for the public.” The fireproof doors are required by city zoning ordinances for several rooms in the building, Hebert said. Construction on the $7.5 million structure—located across the street from the current city offices on Avenue C—was ahead of schedule and city officials were planning for a public open house on April 22. “We haven’t sent out the invites yet,” Hebert said. “Once we get a new date, we’ll inform the public immediately.”
