Property owners in TC3 who need to carry out foundation repairs or house rebuilding will require site-specific geotechnical investigation and specific engineering foundation design.
The Department of Building and Housing is currently undertaking a research trial of foundation systems to test the feasibility and cost of innovation solutions for repairing or rebuilding foundations in Technical Category 3.
The trial is expected to be completed and internationally peer reviewed, with the results and available mid-December 2011. Updated guidance for repairing or rebuilding houses and design guidance in Technical Category 3 Is then expected to be issued by the end of February 2012.
Until these are available we may not be able to access those properties damaged deemed over the EQC cap for each event in TC3, as we will not know what repair options are available for foundation on this land.
