Hi,
I'm trying to find information on how residential properties in Australia are designed to be 'flood resistant' if part of the structure is below the PMF level and is required by the local council.
I know the bridge code AS5100 has information on how to calculate loads from moving water, debris, scour etc. But I can't find anything relevant for residential structures in low lying flood impacted areas.
Is the process normally that a flood report is provided to the structural engineer with the design parameters? If so, what Australian standard is typically used? Or is there software?
For footings I would expect that a comprehensive Geo report is also required that provides other relevant input parameters that are applied in conjunction with the flood report parameters.
I'd just love to understand what the process is in residential.
The situation is only likely to arise when extending to a property that's already in a flood zone. New builds are likely to be very rarely approved otherwise.
Thanks.
Ben
