International planning, design and construction management firm Gannett Fleming is celebrating its 95th anniversary in 2010.

Founded on Aug. 1, 1915, the firm has grown from a two-person office in Harrisburg that specialized in water resources to an international, ISO 9001:2008 Certified company with more than 2,100 professionals.

The firm's planners, engineers, designers, information technology specialists, program managers, construction managers and other professionals furnish professional services from more than 60 offices worldwide. During the past 95 years, the firm has completed projects in every U.S. state and more than 50 countries.

One of Gannett Fleming's key contributions has been the design of many transit systems constructed in the U.S., including the Lindenwold Line in New Jersey, the Detroit People Mover in Michigan and the Market Street Elevated line for the Southeastern Pennsylvania Transportation Authority.

Today, the firm's Transit & Rail Practice is working on projects such as the PHX Sky Train project in Arizona; the Greater Richmond Transit Co. bus operations and maintenance facility in Richmond, Va.; and the Dallas Area Rapid Transit Rowlett Extension project, as well as new assignments implementing positive train control for several clients.

In addition, the firm is positioned to further enhance the nation's mobility with the integration of high-speed rail systems throughout the country.
