Containment and Reduction of Rework in Transport Mega Projects. Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences.

Mega transport projects (>$1 billion) are poorly managed during their construction with significant cost and schedule overruns and benefit shortfalls regularly being experienced. Having to perform rework has been identified as a major factor that contributes to these unintended consequences. As there has been limited research that has empirically examined rework causation, an inability to develop effective rework containment and reduction strategies prevails. This research aims to develop a theoretical model that can be used to develop robust containment and reduction strategies to mitigate the adverse economic, productivity and safety consequences that materialize from performing rework during the construction of mega transport projects.Read moreRead less

The primary aim of this project is to develop an innovative lifecycle semantic–based decision making approach through asset intelligence so as to maximize the operational effectiveness maintenance, repair and rehabilitation planning of infrastructure assets, such as concrete pavement. The research intends to address an important gap by providing logical formalisms and real-time capability to life-cycle asset information through computational intelligence. The expected outcome will be an intelligent asset management platform that provides structured and semantically enriched lifecycle asset information for optimised solutions to help reduce the cost, time and effort in asset information storage and retrieval, and decision-making.

This research aims to develop Rare Event Simulation to quantify the future risk of very rare to extreme floods. Expected outcomes include a framework for the design and maintenance of critical Civil Engineering infrastructure such as dams, extrapolation of extreme storm events beyond the observed record, and an assessment of change in rare flood risk across Australia. The significance of this world-first research lies in adapting rare event simulation techniques that have only been applied to computer system failure before, to water engineering design. With Australian riverine flooding projected to cause $170 billion in losses by 2050, the benefit of this proposal in reducing future infrastructure damage costs and liability is overwhelming.Read moreRead less

Bridge performance assessment through advanced sensing and modelling. This project aims to create cyber infrastructure to manage and maintain civil infrastructure, specifically bridges. Current sensor data interpretation approaches are not good at assessing the performance of civil infrastructure or evaluating the reserve capacity; in particular, they do not adequately account for high levels of systematic modelling uncertainties. This project intends to ease the current scientific data interpretation bottleneck. Expected outcomes are better infrastructure management and maintenance planning, fewer redundant interventions, modified infrastructure and improved future design.Read moreRead less
Condition-Based Maintenance Optimisation for Queensland’s Railways. Rail maintainers currently use time-based (scheduled) approaches to balance the costs and benefits of inspections and maintenance. Changing to condition-based maintenance has the potential to reduce costs and improve track condition.

Rail maintainers currently use time-based (scheduled) approaches to balance the costs and benefits of inspections and maintenance. Changing to condition-based maintenance has the potential to reduce costs and improve track condition. This project aims to enable this approach for rail by developing: 1) new track degradation prediction techniques combining Big Data and engineering knowledge; 2) new on-board sensing capabilities for frequent, low-cost track monitoring; 3) novel inspection and maintenance optimisation methods to efficiently allocate resources. The knowledge generated by this project is expected to decrease maintenance costs, safety risk, and track closures and therefore enhance the affordability and reliability of rail travel.Read moreRead less
The effects of cyclic loading on partially saturated soils. This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numeric ....The effects of cyclic loading on partially saturated soils. This project aims to predict the settlement and strength of the upper, partially saturated layer of the ground when it is subjected to cyclic loading. Most of our critical infrastructure is built on or in this layer, but currently we cannot reliably predict the ground response of partially saturated soils to the cyclic loads that arise from earthquakes, traffic and construction processes. The project is expected to develop a new numerical model that can predict the effects of cyclic loads, and provide updated engineering guidance to ensure the integrity of infrastructure dependent on partially-saturated soils. Improved predictions of the processes involved resulting from this project will have significant economic benefits, as well as ensuring the safety and security of infrastructure and reduced maintenance costs.Read moreRead less

This project aims to improve current engineering analysis methods, which often fail to predict the performance of infrastructure built on natural soft soils. This project expects to develop a theoretical and mathematical framework to describe the response of soft soils to complex loading patterns imposed by transport and energy infrastructure. This will be informed by advanced laboratory experiments that transcend the capabilities of routine testing methods. The expected outcome of the project is a series of tools for the engineering analysis of earthworks and foundations built on soft soils that will underpin the construction of civil infrastructure on ground often too poor to be considered for other use.Read moreRead less

Australian coastal soils often pose significant challenges in the design and construction of railways. The project aims to develop a novel hybrid system of pipe piles & prefabricated vertical drains installed to prevent soft foundation soil (subgrade) from excessive yielding under prolonged cyclic loading by heavy-haul trains. Using large-scale physical model simulations and field trials supported by numerical analysis of soil-pile-drain interaction mechanisms, this innovative concept will be examined to establish a user-friendly design methodology. For rail operators, the outcomes will generate substantially reduced maintenance costs, while extending the longevity of track infrastructure to ensure faster and heavier trains of the future.
