Dikes are vital in providing flood protection to both rural and urban areas throughout BC; designing them with adequate seismic stability and integrity is vital to public safety.
To address the seismic hazard aspect of dike design, the Ministry of Forests, Lands, Natural Resource Operations and Rural Development (FLNRORD) developed a guidance document Seismic Design Guidelines for Dikes in 2011, and updated it in 2014, for all dikes classified by the province as “high consequence”.
To establish the standard of care that Engineers and Geoscientists BC registrants should follow when implementing the FLNRORD guideline, Engineers and Geoscientists BC is developing professional practice guidelines on seismic assessment and seismic design of dikes in BC.
These practice guidelines will strive to bring consistency and increased quality to dike design work, and establish roles, responsibilities, and skillsets of the various participants and stakeholders involved. The guidelines will also outline how professionals can identify various methodologies for assessment and design, address how to appropriately develop an alternative design, provide guidance on adequate documentation, and cover the education, training, and experience required to do this work.
The development of Engineers and Geoscientists BC’s guidelines on seismic assessment and design of dikes has funding support provided by the Fraser Basin Council Society. The guidelines are expected to be completed by the Fall of 2021.
