DOI: 10.1007/S40534-014-0054-Y
Abstract: This study models the impact of the shift from a monocentric private-car-oriented city to polycentric public-transport-oriented city. Metropolitan areas have suffered traffic problems—in particular increase in travel time and travel distance. Urban expansion, population growth and road network development have led to urban sprawl in monocentric cities. In many monocentric cities, travel time and distance has steadily increased and is only expected to increase in the future. Excessive travel leads to several problems such as air pollution, noise, congestion, reduction in productive time, greenhouse emissions, and increased stress and accident rates. This study examines the interaction of land use and travel. A model was developed and calibrated to Melbourne and Riyadh conditions and used for scenario analysis. This model included two parts: a spatial model and a transport model. The scenario analysis included variations of residential and activity distribution, as well as conditions of public transport service.
A proposal for recycling theworld's unused stockpiles of treated wastewater sludge (biosolids) in fired-clay bricks
Publisher: MDPI AG
Date: 05-01-2019
Abstract: Millions of tonnes of leftover biosolids are increasingly stockpiled every year around the globe. Biosolids are a product of the wastewater sludge treatment process. Stockpiles necessitate the use of large areas of increasingly valuable land. Biosolids have many beneficial uses and are currently utilised in agricultural and land rehabilitation applications. However, it is estimated that 30% of biosolids are unused and stockpiled. A second and seemingly unrelated environmental issue is the massive excavation of virgin soil for brick production. The annual production of 1500 billion bricks globally requires over 3.13 billion cubic metres of clay soil—equivalent to over 1000 soccer fields dug 440 m deep or to a depth greater than three times the height of the Sydney Harbour Bridge. This paper investigates and proposes a practical solution for the utilisation of the world’s excess biosolids in fired–clay bricks. The physical, chemical and mechanical properties of fired–clay bricks incorporating 25%, 20%, 15% and 10% biosolids have been tested. Bricks were produced from three different biosolids s les collected at Melbourne’s Eastern Treatment Plant (ETP 22) and the Western Treatment Plant (WTP 10 & WTP 17–29). Compressive strength testing indicated results ranging between 35.5 MPa and 12.04 MPa for the biosolids-amended bricks. Leachate analysis was conducted on the bricks before and after firing, and the results demonstrate that between 43 and 99% of the heavy metals tested were immobilised inside the fired bricks compared to the heavy metals tested in the raw mixture. All leachate concentrations were found to be insignificant for the biosolids-incorporated bricks tested in this study. Biosolids can have significantly different chemical characteristics depending on the origin of the wastewater and the treatment procedure. Suitable leachate analysis should be undertaken on biosolids and test bricks before large-scale production is approved. Scanning Electron Microscopy (SEM) images illustrate that biosolids-amended bricks have a higher porosity than the control bricks, which corresponds to the lower thermal conductivity values recorded for biosolids-amended bricks. In addition, brick firing energy demands are estimated to decrease by up to 48.6% for bricks incorporating 25% WTP 17–29 biosolids due to the higher organic content of the mixture containing biosolids. The emissions study and comparative Life Cycle Assessment results show that the incorporation of biosolids into bricks is a positive and sustainable alternative approach with respect to all environmental impacts arising from the stockpiling of biosolids and brick manufacturing. Based on the results found in this comprehensive study, this paper proposes the inclusion of a minimum of 15% biosolids content into 15% of brick production in order to completely recycle all the approximately 5 million tonnes of annual leftover biosolids production in Australia, New Zealand, the EU, the USA and Canada. This is a practical and sustainable proposal for recycling all the leftover biosolids worldwide. Utilisation of only 15% of biosolids in brick production would reduce the carbon footprint of brick manufacturing whilst satisfying all the environmental and engineering requirements for bricks.

Prioritising sustainability factors for australian community buildings’ management using analytical hierarchy process (AHP)
Publisher: Vilnius Gediminas Technical University
Date: 20-03-2018
Abstract: The essence of Australian community buildings’ sustainable management drives through a previously established decision-making structure with four sustainability aspects and accompanying 18 criteria. Informed decisions are supported with a decision-making model that generates sustainability impacts of building components based on this decision-making structure. Building components’ in idual impacts can be assigned using a numbering scale incorporated with linguistic terms. However, similar importance given to each aspect or criterion is arguable when the combined effect is considered. Hence, they should be given different weightings and their combination with in idual impacts will produce final sustainability impacts. For calculating weightings, the study uses Analytical Hierarchy Process (AHP), widely used technique in Multi Attribute Decision-Making (MADM). The study also conducted an industry-wide questionnaire across Australian local councils because pair-wise comparison data is essential for weighting calculation. This paper presents the survey data and analysis results that captured weightings of sustainability aspects and criteria.

Predicting life expectancy of concrete septic tanks exposed to sulfuric acid attack
Publisher: Thomas Telford Ltd.
Date: 07-2013
Abstract: The attack of concrete owing to sulfate present in sewage is a major problem, both in Australia and worldwide. The prediction of the expected long-term performance of concrete exposed to sewerage and similar environments can be difficult as it is affected by a large number of parameters. In addition the deterioration process in concrete takes a long time to reach a significant level. Whereas considerable research has been undertaken in flowing sewage systems in pipes, little research has been undertaken on static systems contained in septic tanks. A research project conducted at RMIT University has investigated the deterioration of concrete septic tanks located in rural Victoria. A comprehensive set of laboratory experiments was established to measure the accelerated deterioration of concrete under exposure to sulfuric acid. The specimens were manufactured using the same mix design and ingredients used in septic tank production in rural Victoria prior to 1990. The mass changes in the concrete specimens have been recorded and based on the data, a statistical model has been developed to predict the mass change of concrete with time as a function of the cement content and acid concentration observed in sewage.

The Effects of Ocean Salinity Variance due to Climate Change on Australian Seaport Infrastructure

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.438-439.157
Abstract: As the effects of climatic change become more evident and extreme, there is significant pressure being mounted onto port authorities and infrastructure stakeholders to ensure that their assets are resilient to the effects of a more aggressive and corrosive climate. Typically, the reinforcing steel within concrete which provides its flexural strength is protected from corrosion by both the alkalinity of the cement and the distance of cover from the chloride laden environment. However, studies are suggesting that as the hydrological cycle around the equator begins to accelerate, the salinity of the oceans at these lower latitudes (namely from 25°S to 25°N) will increase. As demonstrated through Ficks 2 nd Law of diffusion, there will then be an effect on the build-up of surface chlorides and thus, chloride ingress through the cement matrix to initiate corrosion. Through an extensive literature review of climatic forecasts, and both laboratory and in-field trials, this paper will numerically demonstrate the relationship between salinity concentration and surface chloride levels at varying temperatures. The results illustrate a strong positive relationship between the two parameters suggesting faster corrosion initiation, and more frequent operational downtime for stakeholders into the future. To fill this gap in knowledge, the surface chloride equations presented should be considered when design, maintenance, and retrofitting options are being considered for stakeholders within the affected locations.

Critical risks influencing the application of EERTs in australian green office buildings
Publisher: Trans Tech Publications, Ltd.
Date: 11-1970
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.238.513
Abstract: This paper aims to explore the risks of applying energy efficient and renewable technologies (EERTs) in Australian green office buildings. An online questionnaire survey was conducted in several Australian states and territories to identify and evaluate the potential critical risks that may influence the implementation of EERTs. Consisting of architects, engineers, project managers, and contractors, participants of the survey were asked to evaluate the generic and some specific EERTs risks occurring in the implementation of a selected number of commonly used EERTs in Australian green office buildings. In addition, the participants were asked to pinpoint those stakeholders who were the most affected by the risks and the lifecycle stage of the technology or buildings at which these risks might mostly occur. The data analysis results shows that uncertain governmental policies were identified as the critical risk with the highest mean risk impact value, Lack of access to funds and Presence of system constraints were the most popular risks with influences on most of EERTs. It also identifies the EERTs owners as most affected stakeholders by EERTs risks and that the majority of these risks occur during the operation stage.

DOI: 10.1108/BEPAM-01-2016-0001
Abstract: – Deterioration of timber bridges can often be related to a number of deficiencies in the bridge elements, connectors and/or as a result of been in aggressive environments which they are exposed to. The maintenance cost of timber bridges is affected significantly by a number of deterioration mechanisms which require a systematic approach for diagnosis and treatment. Evaluating the risk of failure of these bridges is of importance in bridge performance assessment and decision making to optimize rehabilitation options. The paper aims to discuss these issues. – This paper identifies common causes for timber bridge deterioration and demonstrates an integrated approach based on fault tree analysis to obtain qualitative or quantitative estimation of the risk of failure of timber bridge sub-systems. Level 2 inspection report for a timber bridge in Queensland, Australia has been utilized as a case study in this research to identify the failure modes of the bridge. – A diagnostic tool for timber bridge deterioration will benefit asset inspectors, managers, and engineers to identify the type, size and the distress mechanisms in order to recognize the proper corrective measures either to prevent or to reduce further deterioration. Timber bridge maintenance is a major issue in Queensland, Australia. If a decision support tool can be developed, it will benefit road authorities and local councils. – Timber bridge maintenance is a major issue in Queensland, Australia. If a decision support tool can be developed as initiated in this research paper it will benefit road authorities and local councils.

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.238.350
Abstract: A research project continuing at RMIT University is exploring the resilience of port structures in a changing climate. Research completed to date comprises of identifying types of port infrastructure vulnerable to climate change, establishing materials and exposure conditions, developing deterioration models based on current knowledge to simulate the effect of climate change on key port infrastructure and modeling the selected elements of infrastructure to derive outcomes which will aid in decision making in port infrastructure management. A considerable effort has been concentrated on identifying input climate data most appropriate for the models developed. The modeling approach is presented in this paper for quantitative projections of damage probability on port infrastructure taking into account the variability of material type, design considerations and environmental exposures with a changing climate. This paper provides a summary of the research undertaken in the development of material deterioration models and their responses to a changing climate load. Using climate information drawn from historical weather records and future climate projections, existing deterioration models were refined to include climate data into modeling runs in order to analyse changes to deterioration rates of different materials when impacted by a change in climate variables. Outputs from this modeling process will assist port authorities in making informed decisions on maintenance and capital budget planning allowing for impacts of climate change.

Selection of emission factor standards for estimating emissions from diesel construction equipment in building construction in the Australian context
Publisher: Elsevier BV
Date: 02-2017
DOI: 10.1016/J.JENVMAN.2016.10.068
Abstract: Emissions from equipment usage and transportation at the construction stage are classified as the direct emissions which include both greenhouse gas (GHG) and non-GHG emissions due to partial combustion of fuel. Unavailability of a reliable and complete inventory restricts an accurate emission evaluation on construction work. The study attempts to review emission factor standards readily available worldwide for estimating emissions from construction equipment. Emission factors published by United States Environmental Protection Agency (US EPA), Australian National Greenhouse Accounts (AUS NGA), Intergovernmental Panel on Climate Change (IPCC) and European Environmental Agency (EEA) are critically reviewed to identify their strengths and weaknesses. A selection process based on the availability and applicability is then developed to help identify the most suitable emission factor standards for estimating emissions from construction equipment in the Australian context. A case study indicates that a fuel based emission factor is more suitable for GHG emission estimation and a time based emission factor is more appropriate for estimation of non-GHG emissions. However, the selection of emission factor standards also depends on factors like the place of analysis (country of origin), data availability and the scope of analysis. Therefore, suitable modifications and assumptions should be incorporated in order to represent these factors.

Quantitative assessment of flood discharges and floodway failures through cross-cultivation of advancement in knowledge and traditional practices
Publisher: Emerald
Date: 15-11-2018
DOI: 10.1108/IJDRBE-09-2017-0051
Abstract: The 2011 and 2013 Queensland, Australia flood events caused massive infrastructure damage for low-level stream crossings such as floodways and culverts in regional Queensland. Failures of newly built floodways during the 2013 Queensland flood event in the Lockyer Valley Regional Council area raised significant concerns with respect to floodway design practices adopted in Australia and attracted significant research interest to enhance the resilience of floodways. Review of existing floodway design guidelines indicates that floodway design process is closely related to hydraulic and hydrological aspects. However, conducting a hydrological analysis is a challenging in rural areas, mainly owing to information scarcity. Floodways in rural areas often require a simple and economical solution contrast to more detailed hydrological analysis approaches adopted in urbanised areas. This paper aims to identify and apply the rational method to estimate maximum flood discharges at selected floodway locations in the Lockyer Valley Regional Council area. The paper further attempts to provide the first insight of flood characteristics during the 2011 and 2013 Queensland flood events at three catchment outputs across the selected case study area. It also highlights modern day challenges for practising engineers and researchers when estimating flood characteristics in rural areas. The paper shows that cross-cultivation of advancement in engineering practices and traditional approaches can promote quantitative approaches when assessing floodway damage in regional areas. The research identifies limitations when assessing flood impact in rural regions in collaboration with experience from industry partners and authors themselves. The authors developed a framework to overcome those limitations arising from information scarcity to minimise the trial and error design approaches utilised in the current design practices for floodways. This paper developed a simple and effective hydrological method with minimum inputs. It also provides an ex le on collating available but scattered resources and traditional method to quantitatively assess flood discharges of a rural catchment in Australia. Flood discharges at three catchment outlets along the Left-Hand Branch Road in the Lockyer Valley Region during both 2011 and 2013 Queensland flood events are estimated for the first time. The findings highlight the impact of flood discharges and flooded period on floodway failures. The current research is based on a selected case study area in Australia. However, similar challenges are expected all across the world, due to the scarcity of rainfall and flood measurement gauges. Floodway designers can apply similar framework to estimate the flood discharges instead of current practice of trial and error process. This will provide more scientific and reliable estimation and assessment process. One of the social impacts identified in the broader research is the community outrages and disagreement between floodway design engineers and the community. Following the developed framework in the manuscript, design engineers will be able to justify their assumptions and design work. The paper presents a novel framework on collating different and scattered information towards estimating flood discharges in rural areas. The manuscript presents the first insights on estimated flood discharges in the selected case study area during the 2011 and 2013 Queensland flood events. This will enable further research to be performed in a quantitative manner rather than the present approach of qualitative manner.
Effect of leaching from freshly cast concrete on pH
Publisher: Thomas Telford Ltd.
Date: 08-2013
Abstract: The pollution of water through release of hydroxyl ions from freshly cast concrete exposed to water can have a detrimental effect on aquatic life by causing a rise in pH. The concentration of hydroxyl ions leached from concrete can be affected by a number of factors. A detailed study has been undertaken to ascertain the effect of parameters such as flow rate, age of concrete after exposure, air quality, cement type, surface area and the volume of concrete. This paper presents the results of the experimental programme and a predictive model for change of pH of water after exposure to freshly cast concrete. Analysis of the results showed that the flow rate was the most significant factor in both the peak pH observed and the time to the peak pH. The volume of the s le was also identified as being a significant factor in the peak pH.

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMR.905.220
Abstract: In the present study, the thermongravimetric analysis (TGA) of laboratory hardwood and softwood particleboard was studied. The TGA showed that both hardwood and softwood have similar thermal behaviour at the same peak temperature. However, softwood is concluded to have higher fire retardancy as more char formation happened in softwood. A further study was carried out to compare the thermal behaviour of laboratory manufactured boards with the commercial grade boards. Superior thermal stability of commercial particleboard had confirmed its effective crosslinking and wood-resin adhesion.

Time Series Behaviour of Aging R/C Bridge Girders beyond Design Stage
Publisher: Trans Tech Publications, Ltd.
Date: 10-2013
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.438-439.855
Abstract: Aging reinforced concrete (R/C) bridge girders, currently in use, exhibit cracks wider than predicted at the design stage. Variation in material properties over time and increase in imposed live loads during service life can be the possible reasons for this behavioural difference. Visual condition monitoring reports of bridge assets do not seem to provide a more quantifiable explanation to this phenomenon. Therefore, authors propose a theoretical time dependent methodology, to predict the crack widths with age. The proposed method takes into consideration flexural stresses, shrinkage and creep. A bridge girder, currently in use, is analysed using proposed theoretical approach and the outcomes are compared with condition monitoring records available.
Application of heat/resin injection in the presence of vacuum for FRP attachments on the concrete substrate
Publisher: Trans Tech Publications, Ltd.
Date: 10-2013
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.438-439.459
Abstract: Advanced processing techniques for the application of Fibre Reinforced Polymer (FRP) materials to repair concrete structures include the adoption of a vacuum consolidation process coupled with heat and/or resin injection to improve the curing process, bond strength and speed of application. The vacuum can contribute to the penetration of the resin into the surface around the exposed aggregates in order to achieve higher bond in strengthened elements. Since, debonding of FRP materials from the substrate is a brittle failure, it is essential to study this phenomenon and propose significant ways to improve the behaviour of the bondline. In this article, the interfacial bond behaviour of FRP laminates attached to concrete in the presence of vacuum and heat/resin injection is studied. The results of single lap shear tests have been utilized to investigate the capability of this system in strengthening of concrete elements. In this regard, several FRP-bonded concrete prisms will be examined in a single lap shear test set-up. Further, the effects of bondline thickness on the bond performance of adhesively bonded joints are studied.

Sustainable Housing Construction to Reduce Greenhouse Gas Emissions
Publisher: Trans Tech Publications, Ltd.
Date: 10-2013
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.438-439.1710
Abstract: Global warming is a reality due to the curent level of greenhouse gas emissions globally. Housing construction should take into account factors which contribute to global warming while making the construction affordable in view of the greenhouse gas emissions and the continually increasing energy costs. It is important that housing construction overcomes the irrationality of the current conventional construction method which is not only expensive but has poor thermal performance and ignores the significant environmental impact of high embodied energy of the building process which contributes to the greenhouse gas emissions. Because of this there is a need for developing improved low cost sustainable building techniques. This paper presents an innovative rammed earth core concrete jacket walling system that can provide significant improvements in environmental impact, comfort and cost of both building the house and the cost of operational energy. The construction uses mainly local natural materials with very little high energy processing there by reducing the embodied energy of the construction. Not only using local materials in this construction but also only basic building skills are required for construction workers and therefore the system is ideally suited to rural areas and has potential application to developing countries. This method of construction has better performance in case of earth quakes which saves many lives. The paper presents a discussion of the efficiency of such high thermal mass solutions and describes the construction process.

DOI: 10.1016/J.WASMAN.2018.01.006
Abstract: This paper investigates the five different gas emissions during the firing process of clay bricks and bricks incorporating biosolids. In this study, three different biosolids produced at the Western Treatment Plant and Eastern Treatment Plant, Melbourne, were used as an alternative raw material to the conventional brick soil to produce bricks. Three sets of bricks were manufactured incorporating 25% of biosolids by weight. Initially, three biosolids s les and brick soil were characterised by their chemical and mineral compositions, organic content and particle size distribution. Brick s les were fired in a tube furnace at a temperature of 1050 °C for three hours. Five different gas emissions - SO
An Investigation of Usability of Brown Coal Fly Ash for Building Materials

Abstract: The Victoria State of Australia has the second largest reserves of brown coal on earth, representing approximately 20% of the worlds reserves, and at current use, could supply Victoria with its energy for over 500 years. Its combustion, annually, yields up to 1.3 million tonnes of fly ash, which is largely use for land-fills. Disposal of fly ash in open dumps cause massive environmental problems such as ground water contamination that may create various health problems. This study focuses on the usability of brown coal fly ash to develop a sustainable building material. A series of laboratory investigations was conducted using brown coal fly ash combined with cement and aggregate to prepare cold pressed s les aiming to test their properties. Initial results indicate that compressive strength satisfies minimum standard compressive strength required for bricks or mortar.

Factors that influence Australian community buildings' sustainable management
Publisher: Emerald
Date: 16-01-2017
DOI: 10.1108/ECAM-10-2015-0158
Abstract: Australia has a huge stock of community buildings built up over decades. Their replacements consume a large sum of money from country’s economy which has called for a strategy for their sustainable management. For this, a comprehensive decision-making structure is an utmost requirement. The purpose of this paper is to capture their sustainable management from four aspects, i.e. environmental, economic, social and functional. The design process follows an extensive review of environmental and life cycle assessments and company context documents. Extracted factors are tailored to community buildings management following expert consultation. However, the resulted list of factors is extremely large, and “factor analysis” technique is used to group the factors. For this, an industry-wide questionnaire across Australian local councils is employed to solicit opinions of the list of factors. The analysis has pinpointed 18 key parameters (criteria) to represent all four aspects. This paper presents the preliminary findings of the factors and the analysis results based on the questionnaire responses. The final decision-making structure incorporates all these aspects and criteria. This can be used to develop a decision-making model which produces a sustainability index for building components. Asset managers can mainly use the sustainability index to prioritise their maintenance activities and eventually, to find out cost-optimisation options for them. Most notably, this is the first study to apply all four sustainability aspects (environmental, economic, social and functional) to develop a decision-making structure for Australian community buildings’ sustainable management.
Condition monitoring and condition aggregation for optimised decision making in management of buildings

Abstract: Buildings are one of the major infrastructure investments in cities. Sustainable preservation of building assets in order to deliver an appropriate level of service throughout their life cycle requires a comprehensive and optimised decision making methodology. This decision making method needs to be supported not only by accurate data, but also by proper manipulation and aggregation techniques to target the highest potential longevity of construction materials. Condition monitoring methods help asset managers collect required information about their buildings to make justifiable judgments for maintenance and rehabilitation strategies. This data is collected in the condition monitoring stage within a defined scope of a condition monitoring manual. The level of detail in data collection may depend on the asset management system, element hierarchy adopted by the organization and criticality of assets. While detailed condition data is collected during building condition assessments, for higher-level optimised strategic asset management overall conditions of element groups are desirable to project the capital investments and expenditures. The paper reviews condition monitoring techniques for buildings and also presents a risk-based methodology for aggregating the inspected conditions to a higher group level of inspected elements which leads to a greater accuracy of decisions to be made for strategic management of buildings.
