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
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

The proposed research will provide our local construction and mining industries with a much needed fast and low cost technology for geotechnical investigation of very large sites which is currently not available. The project will help steer Australia to the forefront of ambient noise research for geotechnical site investigation, in the characterisation of unsaturated compacted soil and in the determination of dynamic site characteristics which are required for seismic risk assessment. Two postgraduate students will benefit from this research by receiving research training at the highest level and it will also pave the way for exporting the technology developed overseas, particularly to our near neighbours in Asia and the Pacific.

Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that wi ....Assessment and Prediction of Particle Breakage under Cyclic Loading. Every year, transport industries spend millions of dollars to maintain existing tracks suffering excessive settlement due to heavy traffic. In railways, differential settlement and track fouling are mostly due to ballast breakage. Frequent maintenance requires large amounts of quarried ballast causing environmental degradation. Simulation of particle breakage subject to cyclic loading is pioneering fundamental research that will have significant impact on the design and maintenance of future rail and road networks. A full understanding of the breakage mechanisms of aggregates will lead to innovative techniques in design and construction, including faster trains carrying heavier loads with reduced maintenance costs.Read moreRead less

Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads. The investigators will establish the most economical means of designing passive blast protection into thin-walled structures and hence, Australia's critical infrastructure. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less
Scaled boundary finite-element shakedown approach for the safety assessment of cracked elastoplastic structures under cyclic loading. Many structures in Australia have passed or are approaching their design life. One of the most common happening in an ageing structure is the appearance of cracks. The safety of a cracked structure is a major concern to general public and government authority if no reliable safety evaluation can be performed.

Many structures in Australia have passed or are approaching their design life. One of the most common happening in an ageing structure is the appearance of cracks. The safety of a cracked structure is a major concern to general public and government authority if no reliable safety evaluation can be performed. In this research project, an advanced numerical tool will be developed to predict the stability of cracks and thus the safety of a cracked structure. Such a tool, which does not yet exist, will help engineers and government authorities in deciding on the necessity and type of rehabilitation, retirement or replacement of a cracked structure.

Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the ....Investigation of Geopolymer based Concretes for the Construction of High Fire Risk Infrastructures. Geopolymer concretes are emerging new materials promising superior fire resistance and durability and potentially cheaper than the widely used high strength concretes, which also consume high levels of Portland cements. Production of 1 ton of Portland cement releases 1 ton of green house gases. Further, the 6.5 million tons/year of cement currently produced in Australia is insufficient to meet the industry demand. This project investigates the use of fly ash to make geopolymer concrete, without using any Portland cement, to find usage for part of the 11 million tons/year of fly ash produced as a waste from coal power stations in Australia.Read moreRead less
