Sustainable Infrastructure

Research opportunities

Focus areas

Sustainable infrastructure underpins the liveability and productivity of major cities and regional communities through effective transport and communications infrastructure, versatile buildings, and delivery of essential services, such as water, gas, and sewer. Maintaining and extending the life of ageing infrastructure and providing sustainable infrastructure for growing populations is a major challenge worldwide. In partnership with our research in Smart Structures, Sensing Technologies and Engineering for Extremes, this research is developing innovative, cost effective and environmentally friendly solutions to infrastructure planning, design, retrofitting, analysis and performance monitoring for the benefit of society. Both fundamental and applied research are synergistically conducted in various facets of infrastructure, including optimisation of transport and structural reliability of roads and bridges, understanding and effectively combating the accelerated deterioration of structures built in corrosive environments, and improving the resilience of water, gas and wastewater infrastructure such as pipelines, sewers and dams under extreme and long-term climatic and man induced loading changes.


To become a leading research group in Australia and in the world that provides innovative and smart solutions to world’s pressing infrastructure problems and that trains future technological leaders to advance the society.


To forecast impending infrastructure problems and provide smart, cost-effective and environmentally responsible solutions for planning, designing, analysis, adaptation and performance monitoring of both existing and new infrastructure systems, for the benefit of the society at large.
