An Unified Approach of Non-Destructive Testing and Evaluation on Building, Civil Engineering and Underground Utility Structures and Material

Organized by


Building Division



Programme Highlights


Nondestructive testing and evaluation (NDTE) technologies are in growing demand because they help engineers and surveyors to see through the ‘unseen’ and diagnose the health conditions of materials and structures in buildings, civil engineering structures and underground utilities. These wave-based technologies are non-destructive, rapid, relatively low-cost and offer data in very high resolution, but also requires high-level skills to interpret the interaction between received NDTE signals and materials/structures. In this talk, Ir Dr Wallace Lai will share his local experience and experience in Germany to demonstrate the usefulness and limitations of NDTE technologies.





Ir. Dr. Wallace W. L. Lai is specialized on research, teaching and consultancy of nondestructive evaluation – civil engineering (NDE-CE) and underground utility surveying techniques since late 90s. He is currently an assistant professor in Department of Land Surveying and Geo-informatics in PolyU, a visiting scientist in Federal Institute of Materials Research and Testing (BAM) in Berlin, Germany, and also a technical assessor listed under the Hong Kong Laboratory Accreditation Scheme (HOKLAS), Innovation Technology Council of the HKSAR Government. Dr Lai’s main research interests include condition survey and diagnosis of engineering structures, underground utilities, construction materials, hydro-geophysics, and site of archaeology values, via nondestructive evaluation (NDE) and near-surface geophysical techniques. These techniques include ground penetrating radar, infrared thermography, acoustic, ultrasound, electrical resistivity, etc.
