For new buildings or alterations and additions to existing buildings completed after 1 July 2004, the Building Surveyor who issues the Occupancy Permit for the building determines a schedule of prescribed essential safety and health measures (Form 46) appropriate to the building which maintenance is required.
For buildings built before 1 July 2004, the owner will need to determine or have determined the appropriate maintenance requirements for their building. For complex buildings it may be necessary for owners to initially engage a specialist to assist in determining the ongoing maintenance requirements. The specialist could be an engineer, building surveyor or maintenance specialist. As a basis to start from, the provisions for new buildings could be used and modified to take account of when the particular features of the building were built and how they were originally required to perform.
