This entity describes The Department of Building and Housing (DBH) technical categories (eg. Technical Category 1, Technical Category 2, etc), indicating how the land in the residential green zone is expected to perform in future significant earthquakes. The technical categories guide the selection of appropriate foundation solutions for houses requiring foundation repairs or rebuilding. If the property has no foundation damage and does not require rebuilding, the technical categories do not apply.Data Source is Tonkin & Taylor who supply updates as a WFS feed on behalf of CERA. The data is 'maintained' inhouse via a bulk archive of existing records from QuakeFoundationDesign then running of an app to repopulate with the latest CERA update. This feature will be intersected with stRatingUnitCentroid for the purposes of Spatial Significance Comment generation and QuakeFoundationDesign records MUST therefore be disassociated BEFORE being archived.It is spatially abstracted to an area.Entity type Concept.
