The 9th meeting of the Construction History Society of America will feature research and scholarship from various academics and practitioners, focusing on building design, fabrication, and construction history. This includes the physical results (infrastructure and building) and the materials, processes, and systems used in their development. We seek a broad range of eras and geographies, and topics focusing on the Americas, particularly the U.S. Midwest, are encouraged.  Presenters will include scholars, engineers, architects, preservationists, contractors, and anyone in the building industry who wants to share their knowledge with us.
