Regency Centers was wrapping up its move from the former Atlantic National Bank Building on Forsyth Street to Independent Square over the weekend. Packing and transporting six floors of furniture and office equipment was a big job. According to Jeff Witwer, director of the Office Moving Division of Suddath Relocation Systems, crews worked 10 12-hour days to load more than 90 truckloads required to complete the task. “Companies only move like this every 25 years or so,” he said.
