Creating, Renewing, Preserving, Sustaining.... This has been the vision of Silman since its inception in 1966. The firm has served as structural engineering consultant on more than 21,000 projects and is noted for its collaborative spirit in the design of new architectural works and on some of the largest and most noteworthy renovations and additions in this country. With special expertise in the engineering of historic buildings Silman has consulted on more than 400 registered landmark-designated buildings. New construction accounts for 50% of its workload. This combined experience with both historic and modern structures has given Silman’s engineers a comprehensive understanding about which technologies work best; they understand both new and old construction, are well versed in the use of all materials, and are willing to create new systems. Silman has long promoted environmentally responsible design and sustainable methodologies in engineering. As early as 1975 they served as a consultant for a US Department of Energy study that investigated methods for reducing not only operating energy consumption, but also embodied energy. As part of its emphasis on green design, Silman has compiled an alternate set of specifications and introduced high performance metrication into all of its designs.
