Earthquake Royal Commission - first technical report

The Royal Commission of Inquiry into Building Failure Caused by the Canterbury and Christchurch Earthquakes has released the first of its technical reports. The Commission has a website here, and all the Commission's technical reports will be made available here.

The first technical report, System of Building Controls is from the Department of Building and Housing. It is a background paper which "outlines the general system of building controls prior to 1991 but not how the system was applied locally by Christchurch City Council. The report also covers the current building regulatory system."

The report can be found here. Information on the content of the report is listed below.
