Recent events in Queensland in 2011 and 2013 have highlighted the vulnerability of housing to flooding and have caused billions of dollars in losses. To reduce future losses there is a significant need for mitigating the risk posed by existing residential buildings in flood prone areas. Therefore, a project is underway within the new Bushfire and Natural Hazards Cooperative Research Centre (BNHCRC) to provide an evidence base to inform decision making on the mitigation of flood risk by providing information on the cost-effectiveness of a range of mitigation strategies. As an initial step to assess mitigation options, after conducting a review of existing schemas, a new building schema is developed to categorise the Australian residential buildings into a limited number of typical building types for which vulnerability functions can be developed. The proposed schema divides each building into the sub-elements of foundations, bottom floor, upper floors (if any) and roof of the building to describe its vulnerability. The schema classifies each building floor based on the attributes of Construction Period, Fit-out Quality, Storey Height, Floor System, Internal Wall Material and External Wall Material. The schema defines 60 discrete building/vulnerability classes based on the above mentioned attributes. It excludes combinations that are invalid in an Australian context. Furthermore, the schema proposes 6 roof types based on material and pitch of the roof.
