Donald Friedman, P.E., F.ASCE, a professional engineer with more than 25 years of experience in the investigation, analysis, and restoration of landmark buildings, has been named a Fellow by the ASCE Board of Direction.
He is president of Old Structures Engineering, PC, a structural engineering consulting firm for historic and old buildings, working for owners, preservation consultants, architects, contractors, and other engineers. Friedman’s design experience includes the integration of modern construction into existing buildings with archaic and obsolete structural systems; the repair and restoration of steel, masonry, iron, wood, and concrete structures; and the investigation of historic buildings to determine structural type and condition.
Representative projects include structural analysis of repair techniques at the 1846-1974 Fort Jefferson National Monument in the Gulf of Mexico; structural design of repairs to the crypts at the landmark New York Marble Cemetery; investigation and alteration feasibility study of Castle Clinton, the landmarked 1810 fort in New York; structural condition assessment of the landmark 1848 John Street Methodist Church in New York; facade analysis and design of new terra cotta supports for the 1906 Langham Apartments in New York; frame analysis and alterations to the 1896 Gerken building in New York; and structural investigation and repair to the tower of the landmark Church of the Holy Trinity in New York.
In addition to Friedman’s project work, he has taught engineering of historic buildings in the building conservation programs at Rensselaer Polytechnic Institute, the University of Massachusetts at Amherst, and Columbia University; he has spoken at numerous conferences including the fourth and fifth ASCE Forensics Conference; he is the author of After 9-11: An Engineer’s Work at the World Trade Center, Historical Building Construction, and The Investigation of Buildings, and the coauthor of Building the Empire State and The Design of Renovations. Refereed papers include “Methodology of Conservation Engineering,” “Cast-Iron Columns in Renovation Design” (in ASCE’s Journal of the Performance of Constructed Facilities), “Hidden Intricacies: The Development of Modern Building Skeletons,” and “Ambiguity in Building Investigation.”
Friedman holds a B.S. in civil engineering from Rensselaer Polytechnic Institute, an M.A. in historical studies from the New School for Social Research, and is a licensed engineer in New York, New Jersey, Pennsylvania, Connecticut, Vermont, Rhode Island, and Massachusetts. He is certified in the practice of structural engineering by the Structural Engineering Certification Board.
