Seismic Mitigation Program
The safety of B.C. students is vital. A comprehensive school seismic upgrading program is underway to make schools safer in the event of an earthquake by minimizing the probability of structural collapse.
Since launching the Seismic Mitigation Program, the Ministry of Education has spent over $1.3B and completed 163 high-risk seismic projects throughout the province, with an additional 13 projects currently under construction, and 8 projects proceeding to construction.
The Ministry currently has another $560M allocated for high-risk seismic projects in our 3 year capital plan.
See the progress for all 342 schools in the PDF below:
Phase one began with district assessments of schools – to determine seismic risk and scope of upgrading work required. Project engineers used retrofit design concepts in the risk assessments that were developed by the Association of Professional Engineers and Geoscientists of BC (APEGBC). Also, the Office of the Auditor General published a report of recommendations for moving forward:
Phase two has continued with the upgrade of several schools as well as various educational components about life-safety during an earthquake. Here are a few noteworthy items:
- New office to accelerate school seismic projects (August 2014)
- Premier announces $584 million to keep high-risk schools on solid ground (April 2013)
- B.C. engineers shake out world-class research on school safety (May 2012)
- $122 million for next round of seismic upgrades (May 2012)
Engineers calculate seismic risk ratings based on the risk of damage from earthquake to a building. This calculation is the foundation for making decisions about how to mitigate risk and making specific locations safer.
Here’s an overview of the risk ratings used for B.C. schools:
|High 1 (H1)||Most vulnerable structure; at highest risk of widespread damage or structural failure; not reparable after event. Structural and non-structural seismic upgrades required.|
|High 2 (H2)||Vulnerable structure; at high risk of widespread damage or structural failure; likely not reparable after event. Structural and non-structural seismic upgrades required.|
|High 3 (H3)||Isolated failure to building elements such as walls are expected; building likely not reparable after event. Structural and non-structural seismic upgrades required.|
|Medium (M)||Isolated damage to building elements is expected; non-structural elements (such as bookshelves, lighting) are at risk of failure. Non-structural upgrades required. Building to be upgraded or replaced withing the Capital Plan when it has reached the end of its useful life.|
|Low (L)||Least vulnerable structure. Would experience isolated damage and would probably be reparable after an event. Non-structural upgrades may be required.|
The government is structurally upgrading schools that have a high risk rating (High 1, High 2 or High 3), as identified in the Seismic Mitigation Program Progress Report (PDF) shown above.
