The Building Code Clause B1 Structure requires buildings and parts of buildings to withstand the loads they are likely to experience during construction, throughout their life and when they are altered. These loads include people, wind, earthquake and snow.
“Guidance on repairing and rebuilding houses affected by the Canterbury earthquakes” was updated in December 2012 and re-released by the Ministry of Business, Innovation and Employment in January 2013.
The guidance focuses on appropriate new foundations for houses and repairs of existing foundations in Technical Categories 1, 2 and 3 (TC1, TC2 and TC3) in Canterbury’s Green Zone. It also offers advice on:
the geotechnical investigation and assessment of subdivisions, structural repairs for existing houses, assessing hillside property and retaining wall damage.
The guidance is aimed at providing appropriate repair and reconstruction solutions that will comply with Building Code Clause B1 structure.
