Part B – Initial Seismic Assessment

The Seismic Assessment of Existing Buildings (the Guidelines) provides a technical basis for engineers to carry out seismic assessments of existing buildings within New Zealand.

Part B of the Guidelines (download) describes the Initial Seismic Assessment (including the Initial Evaluation Procedure, IEP), which provides a broad indication of the likely level of seismic performance of a building. It supports both the identification and the engineering assessment processes for the Building Amendment Act, which are applied using the EPB Methodology.

The IEP Assessment Template (Spreadsheet) provides working versions of Tables IEP-1 to IEP-5. The Assessment Summary Report is used to summarise the key points from ISAs and Detailed Seismic Assessments (Part C) and must be included at the front of all engineering assessments for earthquake-prone buildings purposes.

This web site has a searchable Knowledge Base with answers to questions about the Guidelines. Use article links in the Knowledge Base section to the right to view these.
