Overview
APT and NCPTT partnered to present nondestructive evaluation methods for historic structures. The workshop provided guidance for professionals and students in the use of diagnostic nondestructive testing for historic structures. It was
intended for technically oriented graduate and practicing engineers, architects, preservation consultants, and contractors who are not familiar with this subject area.
Content
The first day dealt with the concepts, theory and approaches to diagnosis in historic structures, using nondestructive testing methods. It included an overview of applicable technical standards and guidelines relating to diagnosis and testing of historic structures, and discussed applicability and the appropriateness of existing standards, and the role of engineering judgment.
The second day consisted of field sessions demonstrating diagnostic test methods on actual structures. The test methods included ground-penetrating radar, in-place tests of masonry, infrared thermography, resistance drilling of timber and digital radioscopy. Simpler diagnostic tools were also available, such as moisture meters and rebound hammers. Stations were set-up for hands-on application at selected buildings. The field sessions were set up to allow groups of attendees to rotate between stations. The attendees were encouraged to make observations and discuss the condition of the buildings, alternative diagnoses, and the meaning of the test results.
