Canterbury Earthquake Royal Commission
A short guide to some documents of heritage interest.Volume 4 which deals with unreinforced masonry buildings their strengthening and performance is of the greatest heritage interest.
Volume 4: Earthquake-prone buildings 
The focus on the CTV building has meant CCC has got of with relatively little attention to its performance with dealing with sub-standard buildings prior to the earthquakes. It is described as passive. Undoubtedly this passivity contributed to the death toll.
Much of the rest oft
the commission's report is highly technical - and  only
specialist structural engineers will cope with all the detail. Still a
skim through these will give some general points. 
With the CTV building the commission coped admirably with a very difficult task:
- Interpreting the
     design against the standards and bylaws of the day which were not well
     developed or consistent
 - Applying
     judgement as to what prudent engineering practice would have
     been at the time
 - Witnesses
     who were sometimes less than forthcoming on their roles.
 
The design inadequacies and the missed
opportunities to correct them are a very unhappy chapter in New Zealand's
professional engineering.
