CPD by Others
Code : 2013085
Event Name : Introduction of Underground Utility Surveying – as a Nondestructive Testing and Evaluation Method
CPD Code : Formal Events
Speaker : Ir Dr Wallace W L Lai
Assistant Professor, Department of Land Surveying and Geo-informatics in the Hong Kong Polytechnic University

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 BAM, and also as 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, electrical resistivity, etc.

Utility surveying is an evolving discipline in Hong Kong as there is increasing demand about locating and diagnosing the densely populated underground utilities. Since open-up is never favorable, different non-destructive/near-surface geophysical evaluation technologies based on wave propagations are always preferred. This seminar will provide an introduction of these technologies and applications to ‘see through the unseen’.
