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
Facilitating intuitive interaction with complex devices for older users. Poorly designed interfaces impact more strongly on older people. Helping designers to make more intuitive interfaces for older community members has great potential for improving their lives and health, and thus benefiting the community generally. Making modern devices easier for older people to use will allow them to participate more fully in society and/or the workplace. This will also help to prevent them from becoming i ....Facilitating intuitive interaction with complex devices for older users. Poorly designed interfaces impact more strongly on older people. Helping designers to make more intuitive interfaces for older community members has great potential for improving their lives and health, and thus benefiting the community generally. Making modern devices easier for older people to use will allow them to participate more fully in society and/or the workplace. This will also help to prevent them from becoming isolated and possibly depressed. This project will apply intuitive interaction to healthcare devices that older people use, which can save costly mistakes and even lives.Read moreRead less
Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated. The inorganic contaminants in sediments can be released back into the water body through mass transfer processes. The mass transfer rate is largely controlled by the wave-driven seepage flux across the seabed. Quantification of this flux is thus a key factor in modelling water quality of coastal water bodies. This project aims to: (1) develop models forwave-induced seepage flux within sediments and ....Contaminant Transport in Marine Sediment. Sediments in bays and estuaries are often contaminated.

The mass transfer rate is largely controlled by the wave-driven seepage flux across the seabed. Quantification of this flux is thus a key factor in modelling water quality of coastal water bodies. This project aims to: (1) develop models forwave-induced seepage flux within sediments and contaminant transport; and (2) establish the link between seepage flux and contaminant transport. Outcomes of the proposed research will enhance the understanding of the mechanism of contaminant transport in marine sediment.Read moreRead less
Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport ne ....Poro-elastic, single domain model of wave-induced transport and transformation of pollutants in coastal sediments. The sediments in many bays and estuaries in Australia are contaminated by pollutants due to discharge of waste from the river, groundwater or/and ocean outfall. Most previous research has had a multi-domain approach and have ignored the wave-dirven advective flow and effects of soil behaviour in coastal sediment. In this study, we will couple the procedure of pollutant transport near the sediment-water interface by a single domain approach, and link wave-dirven advective flow and contaminant in marine sediments. The research outcomes will provide a better prediction of the transformation behaviour of pollutants in contaminated sediments.Read moreRead less
Rigorous Three Dimensional Plasticity Solutions for Soil and Rock Slopes. Slope failures and landslides are a persistent cause of economic loss in Australia. Damages resulting from landslides include both property damage and loss of life. One such recent catastrophic slope failure is the landslide that occurred at Thredbo Village in New South Wales in 1997. This monumental landslide resulted in the deaths of 18 people and was considered by the coroner as the worst natural disaster in Australian ....Rigorous Three Dimensional Plasticity Solutions for Soil and Rock Slopes. Slope failures and landslides are a persistent cause of economic loss in Australia. Damages resulting from landslides include both property damage and loss of life. One such recent catastrophic slope failure is the landslide that occurred at Thredbo Village in New South Wales in 1997. This monumental landslide resulted in the deaths of 18 people and was considered by the coroner as the worst natural disaster in Australian history. The primary aim of this research project is to apply recently developed computational tools to better understand 3D slope behaviour and to develop rigorous stability solutions that can be used by design engineers. A better understanding of 3D slope failure will lead to more economic and safer slope designs.Read moreRead less
Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mat ....Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mathematical and numerical modelling. The theoretical work will be supported by laboratory experiments. The resulting research will provide a better understanding of sand wave migration, beach profiles and the stability of pipelines.Read moreRead less

Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions.

Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less
