UPS spending millions to upgrade customs office in Louisville - Louisville Business First United Parcel Service Inc. plans to spend millions to update the U.S. Customs and Border Protection office at the company's Worldport hub at Louisville Muhammad Ali International Airport. The government agency has design standards for its working spaces, and this project is aimed at making sure its offices at UPS are up to par, said Jim Mayer, public relations manager for the Atlanta-based shipper. The project includes a new conference room, new walls, interior office renovations and an additional storage area, according to a building permit recently filed with Louisville Metro Government. With this project, the company will install additional conveyors to move packages in and out of the customs area, Mayer said. It also will move people within the building to make way for the upgrades.
