Abstract: Service life prediction (SLP) allows materials selection tailored to actual usage and environmental conditions and can guide maintenance and infrastructure planning. To be effective SLP must be done on a country or continental scale while incorporating local effects and building design features. Combining geographic information systems (GIS) with multiscale models (MSM) of material degradation can yield effective SLP. The GIS systems provide an easy means for the user to input specific data about the location and the building and receive life estimates. They are an effective geo-sensitive data base of geographic and climatic data and they facilitate particular spatially sensitive calculations. The MSM integrates models from 10-3m to 10-6m to simulate the processes that control corrosion. Processes include, production, transport and deposition of pollutants onto components, the surface conditions at components, wetting or moisture content of the building material, the degradation of the building material. The MSM runs on a three hourly basis and calculates each factor and the resulting degradation each 3 hours. Degradation on different facades or internal spaces of a building can be calculated separately for buildings across continental domains. The system is used to predict the life of building components across Australia.
