I am keen to hear any information you have in relation to your matter as we are fighting with their repair strategy of notching bearers out to bring rounds in our floors down level or close to where the concrete footing has sunk and pulled the house down into.
We are TC3 blue land and they claim that no geotechnical work will be done and that God is to blame for the ground shaking now.
Thanks

There are LiDAR maps of pre and post earthquake elevation on this site.
This map below shows predicted settlement if we have what is called ULS event. Peak Ground Acceleration of 0.35 PGA.

Let me know if you need any assistance with this.
]]>It appears that they have no data for our area in Hoon Hay and further South, did they assume we did not sink/rise?
This is new growth area for Christchurch, kind of scary if no one knows whether the land was susceptible to bouncing in earth quakes.
In particular we are close to the end of Darfield Fault and the Port Hills Fault, with both the Halswell and Heathcote rivers starting out this way along with the run off from the Port Hills (ponding area).
