Have you received a letter from Council identifying your building as an Earthquake Prone Building (EPB) or asking you to provide an Engineering Assessment?
These assessments indicate the percentage rating of the New Building Standard (NBS) and demonstrate the seismic capacity of the building relative to New Building Standards for a not less than 50-year design life.1 Anything below 34% of the NBS is deemed to be an Earthquake Prone Building.
The Council has to notify you in the timeframes presented in Table 2, as below. Please be aware that demand for Engineers will likely increase towards the deadline and you may struggle to find a qualified professional to assist in the required timeframe. The information below will provide you with some guidance so you can act now.
The tables below have been derived from the Building Amendment Act 2016 and developed in response to the recommendations of the Canterbury Earthquake Royal Commission. They are used by Council to determine if your building is potentially earthquake prone. The types of buildings affected are shown in Table 1.
|All Non-Residential Buildings
Identified by Council as EQP

If you have been contacted by Council or you own property that falls within the categories above, let us know and we can advise you of the most economical and appropriate solutions to undertake. Most importantly, we will ensure that your building upgrades adhere to the guidelines in the most appropriate manner. The table below provides guidance to timeframes for when assessments are required by, and when strengthening work need to be completed.
|Seismic Risk Areas
|Council must identify potential EPBs by:
|Owners of EPB must carry out seismic work from EPB notice in:
|7 ½ years
|12 ½ years
