Robert Silman

President Emeritus of Silman, the structural engineering firm he founded in 1966 (previously known as Robert Silman Associates, P.C.). 

Mr. Silman was a leading expert in historic preservation, as evidenced by his work on Carnegie Hall, Fallingwater, and the Immigration Museum at Ellis Island, to name only a few. In 2004 Mr. Silman was awarded the Anton Tedesko Medal by the International Association of Bridge and Structural Engineers (IABSE) for his pioneering work on sustainability in structural engineering. In 2009 he received the AIA New York Chapter Award for his accomplishments in the field of engineering and for his contributions to the built environment in the City of New York.  In 2010 he received the prestigious Lucy G. Moses Preservation Leadership Award from the New York Landmarks Conservancy. In 2013 Mr. Silman received the Association for Preservation Technology International’s highest honor, the Harley J. McKee award. In 2015 Mr. Silman was awarded the Louis de Pont Crowninshield Award, the National Trust for Historic Preservation’s highest national recognition of an individual.

He had a keen understanding of construction systems in the United States dating back to the country’s earliest building types. For his outstanding professional qualifications the Secretary of the Interior appointed Mr. Silman to the Advisory Board for the National Center for Preservation Technology and Training, for which he was past-Chairman, representing the fields of engineering and preservation education. He was most recently on the faculty at the Graduate School of Design at Harvard where he taught a seminar in the Philosophy of Technology.

Mr. Silman was an international leader in the promotion of sustainable design and green building practices. As Founder of the Working Commission 7 on Sustainable Design for IABSE, he chaired their annual symposium in Rio de Janeiro, devoted to issues of sustainability. He lectured at various conferences and wrote numerous articles on sustainability for Structural Engineering International.  He was a member of the consortium writing the High Performance Guidelines for New York City Capital Construction Projects sponsored by the Mayor’s Office of Construction. In association with the National Trust for Historic Preservation and Friends of the National Center for Preservation Technology and Training, Mr. Silman assisted in writing the Pocantico Proclamation on Historic Preservation and Sustainability. This work was followed with the Nashville Challenge in October 2009, co-chaired by Mr. Silman. He transformed the standard practices at Silman so that the firm’s specifications and design methodologies incorporated and promoted the principles of sustainability
