WS3 - Nondestructive Evaluation Methods for Historic Structures Workshop, Part 2

Sunday, September 23
8:00 AM - 4:30 PM
Location: Buffalo Central Terminal - 495 Paderewski Dr, Buffalo, NY 14212

The use of non-destructive evaluation (NDE) in the assessment of heritage structures is extremely effective in obtaining critical information regarding a building’s structural arrangement and condition. All this can be achieved, while minimizing disruption to the historic fabric. Some preservationists, architects and engineers however, who are unfamiliar with the technologies available may be less inclined to use them due to a lack of education on the subject, and, in some cases, due to a lack of confidence in the results. You no longer are limited to expensive solutions like major rebuilds of masonry walls or intrusive interventions like grout injection or epoxy anchors without knowing the actual internal wall conditions or projected outcomes ...now you can get the detailed information you want and just repair the actual problem area.

NDE of buildings and structures in a very broad sense is the act of understanding how energy behaves (be it light, heat, sound, current vibration, or other) when directed at or passed through a building material or component. Correctly interpreting data collected from techniques that use this energy, such as Ground Penetrating Radar (GPR), Infrared Thermal Imaging, Metal Detection and Ultrasonics is the key to a successful investigation that will ultimately help a project team fully understand their building and design the most appropriate repairs.

The purpose of this 2-day workshop is to explore the most effective NDE technique combinations, provide attendees a hands-on opportunity to experimentation with NDE equipment, and attempt to eliminate some of the confusion and mystery that frequently surrounds the world of NDE.


Day One of the workshop will be held at The Willowbank School in Queenston, Ontario – an impressive 1830s Greek Revival mansion perched above the Niagara River which is the focus of the Willowbank Centre. Day Two takes you to the Buffalo Central Terminal, one of the largest Art Deco train stations in the country, currently on the 2018 World Monument Watch List.
