The methodology is set by the Chief Executive of the Ministry of Business, Innovation and Employment under the Building Act.
It refers to The Seismic Assessment of Existing Buildings: Technical Guidelines for Engineering Assessments (the Engineering Assessment Guidelines) on the building.govt.nz website.
The EPB methodology has three sections:
- Section 1: Territorial authorities identify potentially earthquake-prone buildings. This includes profile categories of potentially earthquake-prone building, category details, and exclusions.
- Section 2: Engineers carry out assessments of potentially earthquake-prone buildings. This includes the engineering qualifications required, deciding what type of assessment is required, and the format of reports.
- Section 3: Territorial authorities decide on earthquake-prone buildings. This includes the criteria for accepting new or previous engineering assessments, how to decide if a building or part of building is earthquake prone and how to determine the earthquake rating for the building.
