The provision of transport and other service infrastructure is a priority of governments worldwide and is of critical importance to future prosperity. Indeed, to reduce traffic congestion, improve freight logistics and accommodate a rapidly growing population, it is predicted that hundreds of billions of dollars will spent over the next decade on rejuvenating ageing transport infrastructure in Australia alone. Due to the massive investment involved in constructing roads, railways, tunnels, ports and pipelines, even small percentage savings resulting from scientific research give large returns in absolute dollar terms. Research conducted in the PRCGSE is providing engineers with new science-based tools for tackling these infrastructure problems, with a strong focus on the delivery of new procedures and software for quantifying risk, providing cost-effective design solutions, managing risk during construction, extending the life of ageing infrastructure, and maximizing the use of sustainable construction materials.

This project provides detail on the project delivery methods adopted on the Pacific Highway upgrade as well as site characterisation, the Ballina Field Test Facilty and the Embankment Prediction Sympoisum.
This project provides detail on physical and numerical modelling techniques employed by researchers at the PRCGSE to improve analysis and design methods for pipelines on geographically challenging areas susceptible to ground movement.
