Civically speaking, we're in an awkward spot. The council had bylaws even before Christchurch, and nationally speaking - after leaky buildings and the like - we were already engaged in general revision of regulations and standards; not only for new buildings, but also a review of every public or commercial building.
There's an emotional assumption that anyone who goes into an old building is in danger of death or injury in "the" earthquake. But the earthquake is unlikely, and it's unlikely to happen here; and the true risk factor is unlikely squared. Even in Christchurch so many lives were lost in modern buildings.
Nevertheless, buildings all over the town are assessed as critically dangerous, to the extent that the council and other owners are shutting and may even consider knocking them down - if they can! It's strange that the assessment seems to take no account of actual construction, but only the age and use of the building and condition of the site. It's a statistical thing.
It's an emotional bind to the extent that any organisation which sees itself as concerned about public welfare is constrained to warn and even evict its tenants. There's an inevitable fear among building owners and controllers, that in the event, they'll be seen as responsible and - as regulations are shaping - it may be so.
It's really a choice between national disaster and sensible government. The disaster is not the earthquake, but the irrational response to a miniscule risk. Instead we need a change of attitude - by legislation if you like - to effect that we work together to recognise and mitigate risks.
