Adrian Wightman, M.Sc., P.Eng. (BC), F.E.I.C., has 46 years of experience in Canada, the US, and overseas, specializing in geotechnical earthquake engineering and its application to foundations and to earth and rockfill dams. He has over twenty years of experience in the design and construction of earthfill and rockfill embankment dams, dam safety review of earthfill dams, reinforced shotcrete face rockfill dams and mine tailings dams. Adrian has experience in the application of ground improvement techniques to foundation and dam engineering problems, including vibro-stone columns, explosive densification, and Dynamic Consolidation. His experience encompasses design, project management, and specialist technical review of water-retaining earthfill and rockfill dams and includes a range of earthquake engineering applications, including seismic hazard evaluation, ground response and subsoil liquefaction assessments, and soil-structure interaction. He was a member of the Canadian reconnaissance team that visited the Koçaeli earthquake zone in the fall of 1999, the Wenchuan earthquake zone in late 2008, and the Maule, Chile, earthquake in 2010. Adrian has also recently completed twenty-five years of service on the Standing Committee on Earthquake Design (National Research Council of Canada).
