Investigating and Understanding the New York State Pavilion’s Tent of Tomorrow and Observation Towers

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.

Can you identify this building? – Series No. 5

Test your knowledge of historic and iconic buildings in the U.S. (and beyond!) in this series of “guess the building” blog posts.

Series No. 5:

These terra cotta faces keep watch over a state capitol from atop what was once the tallest building between New York and Chicago. The building was originally called the “Citadel” and the classically-inspired ornamental motifs include shields, eagles, fasces and medallions. Where is it?

Answer: LeVeque Tower, Columbus, Ohio. This Art Deco skyscraper was built in 1927 by the American Insurance Union and originally known as the AIU Citadel. The architect, C. Howard Crane, is best known as a designer of movie palaces. In 1945, the building was purchased by John Lincoln and Leslie L. LeVeque, inventor of the automatic pinsetter used in bowling alleys.

You Can Help SAVE The Historic Hanging Flume!

The Hanging Flume is the most intact structure of its kind in the United States, and it is the only hanging flume in a condition suitable for preservation, education and interpretation. It illustrates the ingenuity and fortitude of the engineers and miners intent on extracting gold from the land. The Hanging Flume is a historically significant cultural resource recognized by:

  •  The World Monuments Fund – 2006 Most Endangered Sites list
  •   The State of Colorado – Most Endangered Places of 1999
  •   National Register of Historic Places

Time is Running Out to Document the Flume

The Hanging Flume is deteriorating as a result of the ongoing effects of exposure to the elements, falling debris and rock slides, and scavenging. The threat of losing key segments of the flume means the time is now to investigate and document remaining sections before the evidence is gone forever. Previous expeditions have documented approximately 10 percent of the remaining sections of the Hanging Flume. At each location, different construction configurations were discovered. The urgency for conducting this project now is that undocumented segments may contain key information on the construction of the Flume that will be lost as the 130-year-old structure continues to deteriorate.

What We Need & What You Get

Your contribution will help the Interpretive Association of Western Colorado send a team of experts to document additional remaining sections of the flume. The original project team that has made expeditions to the flume and produced technical reports over the past decade is ready to conduct the next phase of investigative work. To get the team to the flume, we only need to raise $20,000 more in order to match over $140,000 already raised!

Contributions at any level are greatly appreciated. Contributors at the $50 level will receive a copy of the 60-minute DVD film about the Hanging Flume, “The Best Kept Secret of the Wild West.” Please share our campaign with your network to make an even greater impact!

Preservation architects, engineers and others involved in the renovation of historic buildings agree on the importance of an efficient and thorough discovery phase. A significant part of that effort is the organized collection of building information and accurate documentation of existing conditions. Even though these discovery tasks are such a significant part of a project, the development and incorporation of tools to improve the process on site and process the resulting information has been slow to develop.

This presentation examines some components of a successful early discovery phase on monumental historic buildings and reviews some technological tools that help to improve the collection and management of graphical and numerical information derived from building surveys.

Series No. 4:

These sculpted limestone panels were spotted during a tower investigation of an early twentieth-century church. You’ll need binoculars to see them in person, since they’re about 80 feet above the sidewalk.

 This church’s architect liked the building so much that he chose it as his final resting place. Where is this lovely bell tower?
P1160256
Answer: Church of the Intercession, New York City. Designed by Bertram Goodhue, the Church of the Intercession was originally built as a chapel of Trinity Church on the site of Trinity’s cemetery in Harlem. Goodhue’s burial vault, sculpted by Lee Lawrie, depicts Goodhue surrounded by images of several of his most famous buildings. In the adjacent cemetery, one can find the burial monuments of John James Audubon and many other famous New Yorkers.
