BackgroundIn 2002, the Timber Framers Guild was awarded a grant by the National Park Service - National Center for Preservation Technology and Training to collect and publish information and illustrate representative examples of heavy timber roof trusses that appear in traditional American timber framed buildings. The work was undertaken by architect and author Jack Sobon (Windsor, Mass.), Ed Levin (Hanover, N.H.), and Jan Lewandoski (Greensboro Bend, Vt). All are nationally recognized authorities on historical timber frame techniques.The grant, in the amount of $19,840.18, was awarded under the Preservation Technology and Training Grants Program, and has resulted in an illustrated catalog to be used by architects, builders, and preservation specialists who are responsible for the care and repair of historically significant buildings. The catalog has been presented as a series of monographs in the Guild's quarterly Journal, Timber Framing. You may access the series of articles by clicking on the links to the left. The National Center for Preservation Technology and Training is an interdisciplinary effort by the National Park Service to advance the art, craft and science of historic preservation in the fields of archeology, historic architecture, historic landscapes, objects and materials conservation, and interpretation. NCPTT serves public and private practitioners through research, education and information management. -- Will Beemer | |||||||||
