Professional practice guidelines produced by the association describe the standard of care that members should follow in providing professional services related to this professional activity and specify the tasks members should perform to fulfill their professional obligations. All guidelines are authored by subject matter experts and reviewed by a variety of stakeholders, depending on the nature of the guideline.
Engineers and Geoscientists BC produces guidelines on specific professional services and activities. On March 23, 2018, the association released a set of professional practice guidelines entitled Performance-Based Seismic Design of Bridges in BC. The guidance in this document supports the application of the performance-based seismic bridge design requirements in the CAN/CSA-S6-14 Canadian Highway Bridge Design Code.
Codes that incorporate performance-based design focus more on the performance expected under varying seismic conditions and less on specific materials, mechanisms, and technologies. The goal is to limit damage, public vulnerability, emergency response, and post-earthquake repair, and to speed recovery. These codes direct design to meet each bridge’s specific operational expectation and acceptable risk. The use of performance-based design should assist in the clear communication of measurable criteria between design engineers, owners, emergency planners, and the public to provide a common understanding of the expected performance of a bridge.
