Architect Bruno Travalja, of Ridgewood, New Jersey, died on Thursday afternoon after falling from the 48th floor of a Midtown Manhattan skyscraper at 6th Avenue and 52nd St. According to the New York Daily News, he bent down to take a measurement and got dizzy when he stood up. He was wearing a safety harness but it wasn’t attached to anything, so the co-owner of Crowne Architectural Systems tumbled over the 18-inch security barrier. The Department of Buildings has launched an ongoing investigation. The residential tower was located at 135 52nd Street, between 7th and 6th Avenues.
