Brief description Coastal Australia is under ever increasing pressure from rapid population growth which requires continual capital investment in civil infrastructure, such as road and rail links and large buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of vacuum preloading, together with vertical drains for soft soil stabilisation, can reduce construction and maintenance costs, while the increased soil strength will enhance the stability of infrastructure. This project will deliver design guidelines and specifications of enhanced vacuum consolidation application, as well as improving industrial competitiveness and export earnings through increased technology transfer.
