Assessing the risk
Council’s general manager community Lance Vervoort said a new building inspection process has been introduced over the past few years where an initial seismic assessment is carried out by an engineer. That’s essentially a desktop exercise that looks at building plans and other key information before the engineer provides a grading system. If it is over 33 per cent of new build standard (NBS) it is classified as an earthquake risk. Buildings under 33 per cent NBS are classified as earthquake prone which requires a detailed seismic assessment, with engineers assessing a number of aspects including core samples, x-rays of the building and profile based on the building is likely to perform in an earthquake. There is no minimum standard under current legislation, however buildingswith an NBS rating of less than 33 per cent mean building owners have 10 years to bring them up to 33 per cent.
