The Canterbury Earthquakes Royal Commission has found design faults in the CTV building that collapsed in the February 22 2011 quake, causing 115 of the 185 deaths that day.

The royal commission’s report on the collapse says the engineer who made the structural design was working beyond his competence and the six-storey office block should not have received a building permit.

It says the building fell because the ground motion of the quake was unusually intense, the engineering design was deficient and there were inadequacies in the construction.

The royal commission has now ended, having made many recommendations on the design, construction and maintenance of buildings in New Zealand. The Government will respond by the middle of this year.
