Abstract
Non-destructive techniques (NDT) for on-site analysis of various structures such as historic buildings and monuments are gaining traction due to inherent limitations of conventional invasive methods requiring sample collection for often off-site assessment. This work will investigate current trends in non-invasive assessment of built structures of historic and/or cultural significance, which include methods such as infrared thermography (IRT), ultrasonic pulse tomography (UPT), ground (surface) penetrating radar (GPR), and others. It will also explore whether NDTs available today can replace traditional destructive analysis methods in physical assessment.
