Canterbury Earthquakes Royal Commission Te Komihana Rūwhenua o Waitaha Canterbury Earthquakes Royal Commission – Te Komihana Rūwhenua o Waitaha

Those who lost relatives and friends in the 22 February earthquake can be assured that there will be a very thorough inquiry into the failure of buildings that resulted in loss of life.
Chair, Justice Mark Cooper
 

New Building Technologies Hearing

In the week beginning 12 March 2012 the Commission conducted a public hearing focusing on the wide range of new building technologies relevant to the rebuild of Christchurch's Central Business District (CBD) and potentially other New Zealand CBDs.

This hearing was a platform for a constructive debate about building design philosophies, for example, 'life safety' versus 'building survivability' and the associated economic impacts. It also discussed new building technologies, some of which were already being implemented in New Zealand, and others which were still emerging. 

Presenters included academics, senior practising engineers and professional engineering organisations.
