Life Cycle Measures of Cost Effectiveness for 4 D CAD in Design and Construct Projects across Industry Sectors. The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD. By combining a 3D computer model of a design with the time dimension of the construction schedule, 4D CAD enables risks and opportunities to be better managed during the design phase and hence avoid co ....Life Cycle Measures of Cost Effectiveness for 4 D CAD in Design and Construct Projects across Industry Sectors. The effective and efficient delivery of complex construction projects will be transformed by the increased application of virtual design and construction technologies, including 4D CAD. By combining a 3D computer model of a design with the time dimension of the construction schedule, 4D CAD enables risks and opportunities to be better managed during the design phase and hence avoid costly issues during construction. However this requires addition design costs which currently represent a barrier to the uptake of this transforming technology. This project will overcome this by developing a flexible framework that allows the benefits gained across the life cycle of a project through using 4D CAD to be set against the additional costs and thus make this emerging technology more attractive to industry. Significantly this research will be based on comparative cases studies across different industry sectors including civil, building, and process engineering.Read moreRead less
Incorporating Design Management Culture within the Total Project Management Process: a Socio-technical Approach. New project delivery methods (e.g. design & construct; alliance contracting) in major commercial and infrastructure projects have the potential to dramatically increase the value added to clients and the wider community.

New project delivery methods (e.g. design & construct; alliance contracting) in major commercial and infrastructure projects have the potential to dramatically increase the value added to clients and the wider community.
However to realise this potential, we need to better understand those socio-technical factors that foster an effective design management culture within traditional construction companies, especially their knowledge sharing culture.
This project will develop and test an innovative research methodology that blends approaches from the social sciences and engineering. The findings regarding design management will have wide applicability to industry and cover civil, building, mining and process engineering projects, each of which has its own culture.Read moreRead less
Development of an adaptive statistical model for oceanic flooding hazards along the East Australian coast. Planning of invaluable coastal infrastructure and housing is critical to the economic and social well-being of Australian communities. Devastating flooding along coasts and estuaries in Australia frequently occurred before 1980, but has been less common since. However, the risks are clear and enormous as demonstrated in recent disasters like Hurricane Katrina and the 2004 Boxing Day tsunami ....Development of an adaptive statistical model for oceanic flooding hazards along the East Australian coast. Planning of invaluable coastal infrastructure and housing is critical to the economic and social well-being of Australian communities. Devastating flooding along coasts and estuaries in Australia frequently occurred before 1980, but has been less common since. However, the risks are clear and enormous as demonstrated in recent disasters like Hurricane Katrina and the 2004 Boxing Day tsunami. Climate change makes flood predictions even more difficult. This project will develop a new adaptive model which accounts for both the present and future climate and also regional variability. The research will be in collaboration with the NSW Dept of Climate Change to enable rapid government action to improve community trust in flood protection. Read moreRead less
Enhanced Analysis of Time Dependent Viscous Behaviour of Soft Clay. Often post construction settlements of structures overlying clayey soils have been observed to be more than those predicted, or the predicted rate of settlement is not correct. The main benefit of this research is providing an accurate but simplified approach, which can be used by practicing engineers to predict the post construction settlement of structures in the design phase of construction projects.

Stabilization of railway subgrade by lime-flyash slurry injection. The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key para ....Stabilization of railway subgrade by lime-flyash slurry injection. The rail network in Australia provides a major transport route for commuters as well as transportation of goods. The subgrade of railway track should provide adequate support for the overlying ballast and capping layers. Hence, a poor subgrade always results in track problems associated with uneven track, fouled ballast, and misalignment of the track. This project will investigate in detail the fundamental mechanisms and key parameters involved in the improvement of subgrade soil by injecting lime-flyash slurry. This project will develop an improved design procedure for lime-flyash slurry injection in the field based on experimental and numerical modelling.Read moreRead less

Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if ef ....Improvement of the performance of water-sensitive geomaterials using hydrophobic additives. Geo-structures such as road and railway bases suffer from water induced damage because they readily interact with the atmosphere and shallow water tables. Under traffic loading, damage to geo-structures occurs as cracking, rutting and roughness, when the strength and stiffness of the geomaterials are compromised by on-going moisture variations. Substantial cost savings to the community can be made if effective methods can be found to minimise such damage. This project proposes to study a novel technique, in which blends of hydrophobic polymer additives are used to increase the stability of geomaterials subjected to varying moisture levels and traffic loading.Read moreRead less
