Member of: EIC Full Interviews
Abstract: Geotechnical engineer Peter Lighthall is a third-generation civil engineer who studied at the University of British Columbia, graduating in 1971. His first job, for BC mining firm Placer Development, involved construction of a tailings dam to impound mine waste for a new mining operation. Earle Klohn, principal of the firm Klohn and Leonoff, was the principal designer. Two and a half years later… more

Abstract: Geotechnical engineer Kwan Yee Lo decided upon graduation in 1957 to do graduate research in soil mechanics at Imperial College London. His Masters of Science work was supervised by Professor Skempton, with Dr. Robert Gibson and visiting Professor Davis from the University of Sydney contributing significantly. In October 1959, he started at the Norwegian Geotechnical Institute, where he… more

Abstract: Geotechnical engineer Dr. Denise Leahy describes her post-secondary education at Laval and the Institute for Geotechnique in Trondheim, Norway. Her first engineering job was as a technician at the La Grande hydro-electric dam at Baie James, where, sue to security issues, women could not work outside the laboratory. After completing her PhD, she took a job at Geocon, an affiliate of Lavalin, where… more

Abstract: Geotechnical engineer Peter Lighthall recalls the 2014 failure of the Mount Polly tailings dam in British Columbia, which released over 12 million cubic metres of water and tailings into a creek and, eventually, into pristine Quesnel Lake. This major upset for the mining industry triggered a review of all tailings dams in British Columbia – which "greatly increased the amount of available work… more

Abstract: Geotechnical engineer Kwan Yee Lo describes his work on the intake and discharge tunnels of the Darlington Nuclear Plant, the largest nuclear power plant in Canada. He worked with a student, Dr. Ogawa from Japan, to predict the in-situ stresses and time-dependent deformations of the intake tunnel during its construction in 1983. The predicted values matched the observed values so well that, when… more

Abstract: Dr. Denise Leahy describes her first job, working in a geotechnical laboratory at the massive La Grande hydroelectric project at Baie James. She was very excited to start field work, but was devastated to learn that, due to security issues, women could not work outside the laboratory. She describes being on a work site with 1000 guys and 100 women as "a learning experience". Eventually she and… more
