Engineers in the U.S. have been involved in historic preservation at least since 1966, the year ASCE's Committee on the History and Heritage of Civil Engineering designated its first National Historic Landmark, the Bollman Suspension and Trussed Bridge at Savage, Md. In 1969, the Historic American Engineering Record was established, followed by the Society for Industrial Archaeology in 1971. To design solutions for the unique problems that affect existing buildings, bridges and monuments, the structural engineer specializing in preservation projects must be part historian and part detective. The article covers main preservation guidelines, archival research and structural investigation, and use of modern nondestructive techniques. Several case histories of preservation projects are included.
