Calgary Geotechnical Society


The Calgary Geotechnical Society (CyGS) is a local section of the Canadian Geotechnical Society (CGS). It provides opportunities for continuing professional development for geotechnical engineers/engineering geologists in the Calgary area. We host lectures by local, national and international speakers roughly monthly from September through May every year. Our current list of events is here.

The society relies on volunteers to help organize and put on the events, and sponsorship from local geotechnical companies and support from the national CGS. If you are interested in helping on the committee, if you have ideas for speakers or topics, or if your company would like to help sponsor the society or a specific event, please talk to one of the committee or contact us at
