The decision from Burnside High School today to close two classroom blocks is illustrative of the wider challenge, which is the persistent misperception of what an “earthquake-prone building” is and is not.
Just because a building is considered earthquake-prone does not mean it poses an immediate danger (there’s a separate classification for those under the Building Act!). Nor does it mean an entire building is necessarily higher risk - another reason to not simply make a decision based off a %NBS rating alone.
More to the point, the legal framework for managing earthquake-prone buildings in Aotearoa is specifically designed to allow building owners time to figure out a remediation process. Large earthquakes are rare. We can, and should, take time to breathe and think thoroughly about how should respond to things like this.
Today’s decision will disrupt students and parents alike - and the reality is that the risk posed by these classrooms has not suddenly changed overnight.
Immediate closures of buildings like this also only feed fuel to existing misperceptions about the relative day-to-day safety (or perceived lack thereof) of earthquake-prone buildings.
If a decision is reached to vacate an earthquake-prone building, that is completely fine (permitted, of course, a holistic approach is taken, considering both the relative risk and impacts of doing so). But this can, and should, be done in a more planned fashion.
Knee-jerk reactions, especially for such important buildings as classrooms, can cause more harm than good.
