PITTSBURGH -- United States Steel Corp. announced Monday it will build its new world headquarters in Pittsburgh as part of the ongoing redevelopment of the former Civic Arena site by the NHL''s Penguins.

Company, team, local and state officials made the announcement at the CONSOL Energy Center, the hockey arena that opened in 2010 across the street from the site where a team-controlled subsidiary will break ground in August or September.

U.S. Steel Chief Executive Officer Mario Longhi said the new headquarters will open by September 2017, by which time the company''s 50-year lease will expire at the 64-story U.S. Steel Tower downtown, the city''s tallest building.

The new headquarters "will serve as a cornerstone in the revitalization of this community and our company," Longhi said. The new five-story building will house U.S. Steel''s 800 headquarters employees for at least 18 years, with an option to extend the lease beyond that.

The plan solves several interlocking problems for U.S. Steel, the Penguins and the city of Pittsburgh.

The steel giant sold its skyscraping headquarters building for $250 million to a New York investment firm in April 2011. A year later, U.S. Steel announced it would likely move out of the building.

What concerned Pittsburghers is whether U.S. Steel would follow Alcoa out of town or greatly reduce its presence, as happened when ketchup-maker H.J. Heinz Co. was sold to Berkshire Hathaway and 3G Capital in 2013. The new owners moved production out of Pittsburgh, though Heinz''s headquarters remain.

When he took office earlier this year, Mayor Bill Peduto met Longhi and said, "I will not be the mayor that lost U.S. Steel."
