Technical clarifications and updates to the Guidance document ‘Repairing and rebuilding houses affected by the Canterbury earthquakes’, and news on the amalgamation of updated section 15.3 (site ground improvement) into Part C of the residential guidance.

This Building Controls Update is a periodic news bulletin for the building sector.

MBIE have released a ninth issue of technical clarifications and updates to the Guidance document ‘Repairing and rebuilding houses affected by the Canterbury earthquakes’, December 2012.

These technical clarifications and updates should be read in conjunction with the Guidance document itself. They have been prepared for professional engineers and others implementing the guidance to provide them with greater explanation, new knowledge, and to respond to new issues that have been raised.

The updates provide further clarification and guidance on the following topics:

  • poly-propylene precast panel shims for packing the tops of piles
  • the relevelling objective when a house is being relevelled
  • required sealant for multi-unit building inter-tenancy walls
  • cavity drainage and sub-floor ventilation for reinstated brick veneer cladding.

Further technical updates will be developed as the need arises. The information from the clarifications and updates will be incorporated into the next version of the Guidance document Repairing and rebuilding houses affected by the Canterbury earthquakes.
