In today's society, current positioning technologies are unable to provide location information with the necessary accuracy, reliability, and low cost, for an expanding number of location aware applications. Locata's positioning technology has the potential to meet these requirements through a network of terrestrial based signal transmitters and GPS integration. The proposed research will provide advanced training to graduate students and enable this technology to be realised. The application of the technology is almost limitless, from surveying and civil engineering projects, manufacturing industries and consumer Location Based Services (LBS), where the benefits would be enormous.Read moreRead less

Summary
Innovative risk analysis, assessment, rehabilitation and strengthening of aging critical civil infrastructure. Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community.

Much essential civil engineering infrastructure such as bridges, buildings, dams, pipelines and pavements was commissioned many decades ago, and sustaining the integrity of this infrastructure in developed nations as it ages is now considered to be a major challenge to the engineering and scientific community. Australia is not spared by the ramifications of its aging civil assets, and identification and rectification procedures that are often ad-hoc now represent a sizeable proportion of the GDP. This Research Network draws together the leading Australian research groups in engineering and applied mechanics in a coordinated program to address this most important cost to the community.Read moreRead less
Characterisation of granular base and sub-base pavement materials under cyclic loading. Pavement construction is a high cost item in road construction. Until very recently, pavements were designed based on empirical rules and restrictive material prescriptions. With the introduction of rational mechanistic pavement design methodology, it has become necessary to reliably characterise the behaviour of road foundation materials under cyclic loading. This project is focused on the characterisati ....Characterisation of granular base and sub-base pavement materials under cyclic loading. Pavement construction is a high cost item in road construction. Until very recently, pavements were designed based on empirical rules and restrictive material prescriptions. With the introduction of rational mechanistic pavement design methodology, it has become necessary to reliably characterise the behaviour of road foundation materials under cyclic loading. This project is focused on the characterisation of unbound granular base and sub-base materials. Since these are geo-materials, geotechnical concepts such as the influence of stress path will be used. This project will lead to better roads at lower cost, and significant leap in know-how in pavement design and material specification.Read moreRead less
Ellipsoidal physical geodesy - improved global and local gravity field modelling. Improved techniques for gravity field modelling, using the ellipsoidal approach proposed in this research, will increase the accuracy of the Australian geoid model. A more accurate model of the geoid will bring great cost-benefits mainly to the Australian surveying, mapping and exploration community. For example, height determination from GPS [Global Positioning System] or similar satellite-based measurements is on ....Ellipsoidal physical geodesy - improved global and local gravity field modelling. Improved techniques for gravity field modelling, using the ellipsoidal approach proposed in this research, will increase the accuracy of the Australian geoid model. A more accurate model of the geoid will bring great cost-benefits mainly to the Australian surveying, mapping and exploration community. For example, height determination from GPS [Global Positioning System] or similar satellite-based measurements is only possible with the aid of an accurate geoid model. This will allow the use GPS to its full capacity and save valuable time and money (by as much as a factor of 10).Read moreRead less
Laboratory and Theoretical Investigation of Soft Clay Behaviour under Cyclic Loading Stabilised by Prefabricated Vertical Drains. Coastal Australia is under increasing pressure from rapid population growth that requires continual capital investment in civil infrastructure such as road and rail links, ports and buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction.

Coastal Australia is under increasing pressure from rapid population growth that requires continual capital investment in civil infrastructure such as road and rail links, ports and buildings. Many regions have soft compressible clays that present challenges for infrastructure design and construction. The use of prefabricated vertical drains (PVDs) in stabilising soil can reduce construction and maintenance costs, and increased soil strength will enhance the performance of infrastructure. In this project, the soil behaviour under cyclic loads stabilised by PVDs will be thoroughly investigated. Extensive laboratory testing will result in more efficient design and construction on soft soils, including roads, railways and airport runways.Read moreRead less

The development of knowledge of HCTCRB, an advanced material in the pavement engineering discipline, will underpin growth in the highway and road construction industry. The key outcomes of this study will enhance and change highway and road organisations, contractors, engineers and others interested in the use and design of pavement materials. This is particularly so in light of the recent change to a new era of analytical approaches, rather than the empirical approach of the past. When the outcomes of this project are applied, they will result in an improvement in overall road and highway quality. Read moreRead less
High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators wi ....High Strength Steel Protection Bollards. Terrorist attacks cost Australians much human grief and millions of dollars. Prevention of an attack is paramount. Passive road bollards are commonly used to stop a vehicle approaching and/or entering security sensitive infrastructure. Thin-walled tubes are used to manufacture such bollards. However there is a lack of knowledge about their behaviour, and in particular high strength alloy steel bollards, when subjected to impact loads. The investigators will apply their extensive knowledge in thin-walled tubular structures to establish the most economical means of designing high strength bollards. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
Development of a Risk Assessment and Cost-Effectiveness Model for Optimising Geotechnical Roadway Assets. Roadway performance is strongly a function of the topography and foundation conditions through which the roadway passes, dictating the need for cuttings and fills, and approaches to handle problematic foundation conditions.

Roadway performance is strongly a function of the topography and foundation conditions through which the roadway passes, dictating the need for cuttings and fills, and approaches to handle problematic foundation conditions. The project aims to develop a risk management model to minimise the geotechnical risks and costs involved in roadway construction and maintenance, and maximise design life. In Queensland, the value of roadway geotechnical assets is about $ 7.5 billion, with $ 0.5 billion spent annually adding to and maintaining these assets. The expected outcome of the project is maximising the life of geotechnical roadway assets for the funds available.Read moreRead less

Australian Research Council has recognised water as a critical resource that must be protected from wastage. Along with water, the supply of gas to communities through extensive buried pipe networks is an essential service. As the pipe systems age, the pipe failures have increased. These failures lead to loss of valuable commodity and inconvenience and health hazard to public and workers. Effective asset management tools are urgently required in predicting and controlling pipe failures. A consortium of water and gas suppliers and a team of researchers from Monash University and CSIRO have joined forces to address this problem so that significant social and economic benefits to Australia can be realised.
