In April of 2015, the Friends of NCPTT, the World Monuments Fund, the American Institute of Architects St. Louis, Washington University in St. Louis, and the Jefferson National Expansion Memorial partnered to jointly present a symposium on the preservation of Mid-Century modern structures in St. Louis, MO. This three-day event brought experts together to present an in-depth understanding of the history, use, and preservation of materials found in Mid-Century modern architecture.

Evan Kopelson, partner at Vertical Access and Nancy Hudson, associate at Silman,  co-authored the presentation Investigating and Understanding the New York State Pavilion’s Tent of Tomorrow and Observation Towers.  It gives an overview of the New York State Pavilion’s innovative design and engineering, describes the current condition of the Tent of Tomorrow and Observation Towers, highlights the importance of archival research in revealing construction methods and details, and addresses reuse challenges.  The entire presentation is available for viewing below.
