Making Wellington (Earthqueake) Resilient: Creating Building Inventory Dataset for Seismic Risk Assessment and Management
Wellington City Council earthquake resilience strategy began addressing the city’s building stock as early as 1970’s. Major events that shook our country during this decade (in particular the Kaikoura earthquake) highlighted information gaps in the form of scarce of detailed and up-to-date information about the existing stock of buildings in a high earthquake risk city like Wellington. Our project has assembled an inventory of mid- to high-rise buildings in the Central Business District to facilitate multidisciplinary research within Flagship 3’s Coordinated Project. Crossing over the engineering and social sciences, the ongoing projects supported by the building inventory are: (1) providing best scientific knowledge about the expected seismic performance of concrete buildings; (2) assessing the impact of multiple building failures including the downstream consequences of associated cordoning; (3) developing a path for seismic retrofitting that includes prioritization of retrofits and (4) informing the design of a regulatory structure that can facilitate the reduction of risk associated with earthquake vulnerable buildings. The inventory dataset is hosted online in a MapViewer where researchers can visualise, filter and download spatial and attribute data of either the entire inventory, or buildings that satisfy specific criteria. Researchers can access the data in GIS conventional formats (as a file relational geodatabase or a Web Feature Service) or non-GIS file formats (e.g. csv files). Further developments include the addition of geophysical information (e.g. hazard information) and socioeconomic data (e.g. Land values). Ultimately, the inventory is intended to be a core input for seismic risk assessment and management, as well as a methodology that can be replicated in the greater Wellington and other parts of NZ.
