NEW YORK – Authorities are investigating the death of an architect who fell to his death after apparently getting dizzy while working on the roof of a New York City skyscraper.

Police say 52-year-old Bruno Travalja of Ridgewood, New Jersey, died Thursday afternoon after plunging from the roof of the 42-story building in Manhattan.

Police say Travalja took off his harness and knelt down to take some measurements when he became dizzy and fell. He fell onto a second-floor landing and suffered severe trauma to his body. He was pronounced dead at the scene.

The Daily News, who reached his wife, reported that he was the owner of Crowne Architectural Systems in North Bergen, New Jersey. Alexis Travalja told the newspaper that she and her husband started the firm that builds windows and curtain walls in their basement 11 years ago.
