- assess what has happened to your house,
- assess what options there are to fix the damage,

- compare the proposal with what independent specialists recommend, and
- check what has been done.
Part 1 – People
Members of the New Zealand Institute of Building Surveyors are professionals with the expertise to assess buildings (but not a geotechnical assessment of the land) and are often used for pre-purchase inspections in real estate transactions. The Institute has a website here. The things they look at in a survey are here.
Part 2 – Publications
The best place to start is with the Department of Building and Housing’s booklet Guidance on house repairs and reconstruction following the Canterbury earthquake – A summary of geotechnical and structural engineering recommendations to guide house repairs and reconstruction. It can be downloaded from here.
Despite the lengthy title it is a relatively short summary of events, issues relating to the land and what will be involved in repairing and rebuilding houses. The contents cover a range of house types and after a while you will get the hang of the layout and be able to skip the bits that don’t relate to your house. For more details of the booklet check out the blog covering it dated 29 December.
Another useful guide is Winstone Wallboards Ltd. bulletin Guidelines for Repairing Gib Plasterboard Linings in Wind or Earthquake Damaged Properties. Make sure you are looking at their Technical Bulletin – Version 2, issued November 2010. It has been available at many hardware stores but was/is out of print. A copy can be downloaded from here.
This is a 4 page bulletin which helps identify different types of damage and how the gib board should be repaired or if it should be replaced.
