The Building Code of Australia (BCA) is the principal code under which building approvals in Australia are assessed. The BCA adopted performance-based solutions for building approvals in 1996. Performance-based codes are based upon a set of explicit objectives, stated in terms of a hierarchy of requirements beginning with key general objectives. With this in mind, the research presented in this paper aims to analyse the impact of the introduction of the performance-based code within Western Australia to gauge the effect and usefulness of alternative design solutions in commercial construction using a case study project. The research revealed that there are several advantages to the use of alternative designs and that all parties, in general, are in favour of the performance-based building code of Australia. It is suggested that change in the assessment process to streamline the alternative design path is needed for the greater use of the performance-based alternative. With appropriate quality control measures, minor variations to the deemed-to-satisfy provisions could easily be managed by the current and future building surveying profession.

The risks associated with extreme weather events induced by climate change are increasingly being recognized, and must be addressed through each country’s construction regulations, building codes, and standards. Ensuring that buildings and cities are resilient against disasters is becoming more important. Few studies have analyzed the impact of global polices and frameworks in reducing disaster risks and increasing resilience in built environments. This research reviews disasters associated with climate change in the Sendai Framework for Disaster Risk Reduction 2015–2030, analyzing how Australia’s National Construction Code is aligned with the framework and the potential implications for reducing disaster risk. Decision-makers in construction companies in Sydney, Australia, were surveyed. The results show there is a statistically significant link among the National Construction Code, the Sendai Framework, and building resilience. The Sendai Framework is an effective mediator in this three-pronged relationship that can further enhance building resilience in Australia. Stakeholders in the construction industry will need to incorporate disaster risk reduction practices, especially authorities, such as local governments, building commissioners, and building certifiers that are responsible for the approval, quality, and defects mitigation of development applications and best practices. Overall, implementation of the Sendai Framework will help develop more regulations and standards for resilient buildings, set targets, and make improvements over time in the Australian construction industry.

Earthquake Engineering in Australia, as elsewhere, has been formatted in the aftermath of damaging earthquakes. The first Australian Code AS2121-1979 was written and published after the 1968 Meckering WA earthquake. The second AS1170.4 1993 was published after the 1989 Newcastle NSW earthquake. Good quality Building Codes are a necessary basis for sound earthquake resistant designs. Both implementation and enforcement of the codes and sound robust construction in the field are essential for the protection of life and infrastructure. Also essential is the preservation and upgrading of the earthquake database. A study to assist the safer operation of emergency services immediately following damaging earthquakes is proposed.

To reduce greenhouse gas emissions, nations have introduced energy efficiency regulations for new and existing buildings. This has been considered advantageous as more efficient building envelopes would reduce energy consumed to heat and cool home interiors to within accepted thermal comfort bandwidths. However, as these methods have been adopted, many nations have identified an unintended visible presence of surface and interstitial condensation and mould in new code-compliant buildings. In Australia, it has been estimated that up to 50% of Australian houses constructed in the last decade (2006–2016) have a presence of condensation and mould. Australia introduced its first condensation and mould-related building regulations for new homes in 2019. This paper reports on the hygrothermal and mould growth analysis of the most common low-rise residential external wall system, a timber-framed clay masonry veneer wall. A key component of this paper discusses the application of innovative methods in the Australian context. The external wall’s moisture accumulation and mould growth were simulated for a period of ten years using the transient hygrothermal simulation tool, WUFI® Pro, and the mould growth model, WUFI® VTT. This study identified significant risks for this typical external wall system when constructed in a temperate climate.

Abstract In Australia, one-third of new constructions are affected by condensation and about 50% of buildings suffer from mould risk, mainly due to inappropriate design and management strategies. Despite the potential structural damage and serious health hazards, there is a lack of preventive moisture management strategies at the legislative level. The first hygrothermal management provisions were adopted in the National Construction Code only in 2019, with very general indications that correlate the breathability of the membranes with the climate zone. However, the building code identifies only eight zones for the entire Australia, which were originally developed for thermal analysis and energy efficiency provisions. The result is a coarse climate grid that clusters locations with highly variable humidity conditions. This paper undertakes a semi-empirical approach to identify whether the current climate zones are suitable for hygrothermal purposes. This research represents the first step towards an Australian-specific moisture risks management framework, and it advances the discussion about the suitability of the current hygrothermal design and construction policy and practices. The outcomes reveal the highly variable moisture indices obtained for the different representative cities, affirming the inappropriate use of existing climate zone clustering for hygrothermal assessment purposes.

Abstract Responsibility for housing people with a disability has rested with government and the charity-medical model of disability encouraged institutionalized accommodation. However, since the mid-2000s, the introduction of a person-centred approach has seen government’s legislate programs that facilitate people with disabilities living in the community. This shifted supply of appropriate housing to the private-sector and placed a focus on whether current building regulations are capable of regulating in this space. This paper explores the history of building regulations in Australia, in parallel with the history of treatment of people with a disability. The normalization of institutionalizing people with a disability was reflected in early building codes in Australia, continuing from the 1840s until the 1980s when disability theory began to change – but not building practice in Australia. The decisive break between the approach to disability accommodation (person-centred) and the institutional model in building regulations occurred with the move to the National Construction Code (NCC) in the 1990s. The introduction of the National Disability Insurance Scheme (NDIS) in 2014 highlighted the disconnect when a market-based housing model was proposed that proved difficult to implement with current NCC settings. This study highlighted the complex interaction between existing policy settings and identified the scope for individual interpretation of the code around key concepts. These include building classification, single-occupancy units, and fire safety. As a consequence of the institutional model for disability accommodation enshrined in the NCC, the NDIS is undermined in accommodating people in the community, due to uncertainty and confusion within the private-sector industry that has impacted the cost and quality of the housing produced.

As a prelude to the planned harmonization of building codes in Australia and New Zealand, this paper illustrates the seismic hazard in the two countries for discussion purposes. Hazard maps for peak ground acceleration for a 475 year return period are presented, and also for 2500 year return period in New Zealand, along with typical response spectra. It is shown that the hazard in the least seismic parts of New Zealand is similar to that of the more seismically active parts of Australia. The eventual harmonized loadings code would accommodate regional differences in hazard by using different response spectra and zone factors appropriate to the different regions of the two countries.

Purpose – The purpose of this paper is to explore the barriers preventing investment in the re-use of low-grade multi-storey building stock in order to identify attributes that determine whether an existing building is suitable for retrofitting. Design/methodology/approach – Semi-structured interviews were undertaken with key industry practitioners to investigate existing practices and barriers facing low-grade building retrofits and what “ideal” multi-storey building features represent a successful investment opportunity. Findings – The findings showed that tenant commitment is necessary before any project goes ahead and that there exist many barriers influencing the investment decision. These include: high levels of asbestos found in existing buildings; changes in the National Construction Code necessitating enhanced fire safety and disability access; heritage listing; lack of awareness; overestimation of costs involved on simple and effective energy efficiency upgrades and change in tenant demands towards modern and efficient open plan offices. Many low-grade structures are privately owned inherited assets where the owners lack the expertise and capital to undertake retrofitting effectively. Research limitations/implications – The study is focused on the Adelaide CBD in South Australia but the findings are relevant to other Australian cities. Practical implications – There is room in the market for more positive and influential schemes such as the Green Building Fund that encourage more energy efficiency upgrading of these buildings. Social implications – The greater occurrence of retrofitting and re-use of older buildings, rather than demolition and rebuilding, has advantages with regard to reducing the impact of buildings on the environment and promoting sustainability. Originality/value – The research has indicated certain features of older buildings which render them as suitable candidates for retrofitting and refurbishment.

A series of ductile moment resisting reinforced concrete frames are sized to meet the minimum seismic provisions of the New Zealand Loadings Standard, NZS 4203-1992, the Draft NZ/Australian Loadings Standard, the Uniform Building Code, UBC-1997, the International Building code, IBC 2000 (1998 draft) and Eurocode 8 (1998 draft). The results of the analyses allow valid comparisons to be made between the different codes. It is shown that comparisons of individual clauses can be misleading due to the many interactions that occur between clauses.
Comparative analyses were made for the buildings described above located in both high and low seismic regions. It is shown that the strength and stiffness requirements for both the New Zealand Loadings Standard and the Draft Standard are low compared with the other codes of practice in the high seismic zone. It is recommended that the required design strengths in the Draft NZ/Australian Standard be increased.

Australia and indeed the Asia-Pacific region is facing a significant decommissioning workload. Recent work by the Centre of Decommissioning Australia (CODA) puts Australia’s potential offshore decommissioning cost at around US$40 billion and Wood Mackenzie predicting the region’s decommissioning to be in excess of US$100 billion. CODA was established in 2021 to support the coordinated effort required across the entire Australian value chain to address this immense domestic workload safely and effectively. Building on the release of the 2021 liability report, CODA, in conjunction with a number of operators, has undertaken three additional studies, looking at: planning and execution global best practice applicable to Australian operations; a decommissioning technology roadmap, and; a recycling and disposal pathways report. Supported by these studies to understand the current state and needs of the Australian decommissioning industry, CODA’s primary focus is to build domestic capacity and capability. To this end CODA is working with operators, the service and supply sector, state and federal government, regulators and researchers to establish a collaborative network that can enhance the visibility of upcoming work, surface and support the growth of domestic capability and share best practice in decommissioning. This paper highlights findings from the new reports and shares insights into CODA’s ongoing work to build an inclusive Australian decommissioning community of practice ready to undertake the next decades of activity.

Over the last 15 years, since introductionof the Disability Discrimination Act (DDA)(Commonwealth Government of Australia,1992), there has been much discussionabout the extent and nature of buildingaccess for the disabled, particularly inresponse to proposed revisions to theBuilding Code of Australia (BCA) and theintroduction of a Premises Standardcovering building access. Much of theargument which contributed to the twoyear delay in submitting a final version ofthese documents for government approvalrelated to the extent of access provisionsand the burden of cost. The final versionsubmitted to government by the AustralianBuilding Codes Board (ABCB) (notreleased publicly) appears to still containinconsistencies between the DDA and theBCA in several areas such as wayfindingand egress.In the debate preceding submission of thefinal version there appears to have beenlittle reference to access requirements forindividuals with intellectual disability (ID).This may be due to a general lack ofresearch on the topic. Consequently, thispaper uses a combination of theknowledge gained from a limited numberof previous wayfinding studies, literaturedescribing general problems faced bythose with ID and the author’s personalexperience observing others with ID tocreate a list of probable difficulties andsuggested solutions. The paperconcludes with a discussion about theassociated cost implications and benefitsin providing the required access.

Waterproofing is an essential component in building construction to maintain the integrity of buildings with reduced maintenance cost. A comprehensive waterproofing system is an integrated combination of factors, and includes product selection, membrane detail, substrate preparation, design, installation and maintenance. It is designed to work under different environmental conditions, substrates and applications. Proper understanding of the issues related to waterproofing membrane systems is important to minimise the waterproofing failures in both commercial and residential buildings. This paper aims to discuss Standards and Codes; membrane systems and performance, waterproofing practices, design and installation techniques, inspection and testing and quality assurance adopted by the waterproofing industry in Australia.

Low-carbon building regulations are acknowledged as critical instruments to facilitate the building industry’s decarbonization transition. However, recent studies have shown that non-compliance with low-carbon requirements is under-researched, leading to a significant divergence between policy intentions and actual performance. In light of this, the paper aims to provide a synthesis of existing research on non-compliance with low-carbon building regulations. It does this using a systematic literature review combined with bibliometric and text mining techniques. Through reviewing 26 scholarly works from the last decade, the paper demonstrates a peak production year around 2015, the year of the Paris Agreement, with the USA and Australia as key countries of concern. Subsequently, the study reveals three focused research areas: the development of building policy during the low-carbon transition; the role of building energy performance requirements in achieving low-carbon buildings; and building energy code compliance. Findings suggest widespread non-compliance with building energy codes and also indicate influencing factors and associated enhancement strategies. Finally, the paper identifies gaps in the investigation of new forms of building energy codes; an inconsistent conception of compliance; and a lack of understanding in building practitioners’ compliance behavior. The study contributes to knowledge by providing future research areas in this under-researched topic and by successfully applying both bibliometric and text mining analysis in the construction management domain. This is found to have advantages in terms of time efficiency and objectivity. It also offers practical implications for industry by minimizing the gap between policy intentions and real compliance performance.

National design guides provide essential guidance for the design of building drainage systems, which primarily ensure the basic objectives of preventing odor ingress and cross-transmission of disease through water-trap seal retention. Current building drainage system design guides only extend to buildings of 30 floors, while modern tall buildings frequently extend to over 100 floors, exceeding the predictive capability of current design guides in terms of operating system conditions. However, the same design guides are being used for tall buildings as would be used for low-rise buildings. A complicating factor is the historic roots of current design guides and standards (including the interpretation of the governing fluid mechanics principles and margins of safety), causing many design differences to exist for the same conditions internationally, such as minimum trap seal retention requirements, stack-to-vent cross-vent spacing, and even stack diameter. The design guides also differ in the size and scale of the systems they cover, and most make no allowance for the specific building drainage system requirements of tall buildings. This paper assesses the limitations of applying current building drainage system design guides when applied to the case of tall buildings. Primarily, the assessments used in this research are based on codes from Europe, the USA and Australia/New Zealand as representative of the most common approaches and from which many other codes and standards are derived. The numerical simulation model, AIRNET, was used as the analysis tool. Our findings confirm that current design guides, which have been out of date for a number of decades, are now in urgent need of updating as code-compliant systems have been shown to be susceptible to water-trap seal depletion, a risk to cross-transmission of disease, which is a major public health concern, particularly in view of the current COVID-19 pandemic.

This paper considers why mathematics is used in physics. It traces the use of mathe-matics in physics through primary school, junior high school and senior high school in NSW, Australia, considering its role from the point of view of Systemic Functional Linguistics and Legitimation Code Theory. To understand the development of mathematics, two genres that play differing roles in the discipline of physics are introduced: ‘derivation’ and ‘quantifica-tion’. Through an analysis using the concepts of semantic density and semantic gravity from Legitimation Code Theory, these genres are shown to aid physics in developing new knowl-edge and linking its theory to the empirical world. This paper contributes to the growing body of research considering forms of knowledge in academic disciplines and the role of non-lin-guistic semiotic resources in organizing this knowledge.

Purpose – The loss of heritage buildings should be avoided as they provide a tangible example of a period of life that is now gone. Adaptive re-use enables buildings to be given a second life, enabling them to live on when they may have been previously underutilized. Changing the capacity, function or performance of underutilized buildings for a different purpose, or to suit new conditions, or making use of pre-existing structural elements has become necessary to preserve heritage buildings. The purpose of this paper is to identify the critical success factors (CSF) for the adaptive re-use of heritage buildings. Design/methodology/approach – Identification of CSF for adaptive re-use can provide asset owners, developers and key stakeholders with the knowledge needed to ensure a project is delivered successfully. Due to a lack of research in the area of CSF for heritage buildings, an exploratory approach was undertaken. Semi-structured interviews were undertaken with stakeholders to solicit their views as to CSFs that lead to the successful adaption of all heritage buildings that had been subjected to re-use program in Perth, Western Australia, were examined. Findings – Four CSFs were identified: research; matching function; function; and design and minimal change. It is proffered that by addressing the CSFs issues associated with latent conditions, building layout and commercial risk and uncertainty can be addressed. Yet, the Building Code of Australia will continue to be the most significant issue for owners/developers and project teams who embrace an adaptive re-use project. Originality/value – To date there has been limited research undertaken with regard to determining the CSF for heritage buildings that have been subjected to adaptive re-use. The work presented in this paper identifies the key CSFs that emerged from the stock of heritage building’s in Perth, WA. Further research is required to determine the validity of the CSFs, however, those identified provide a benchmark for further studies in this fertile area.

Design for manufacture and assembly (DfMA) is an important part of the future of the construction industry due to the promise of speed of project delivery, quality control, worker safety, and waste minimization onsite via the purposeful design for manufacture and assembly offsite. However, the adoption of DfMA in Australia has been slow. This paper investigates the barriers prohibiting widespread uptake and how digital construction will be a catalyst for improving use on commercial-scale projects. A total of six leading experts were interviewed to elicit their opinions, and seven recent case studies of high-rise modular apartment and hotel buildings constructed by Hickory were cross-referenced as evidence of DfMA capability. The experts suggested that the reasons for slow adoption in Australia were community mindset, government regulations and incentives, planning and building codes, unionization and business politics, finance, and supply chain management. The case studies suggest that compatible building type and transportation distance are also factors. These barriers can be addressed by the clever integration of building information modelling tools with lean construction processes as part of a proposed strategy leading to smarter (more productive) and better (more sustainable) outcomes predicated on growth in digital construction practices. The paper concludes with a proposed framework for change that conceptualizes the ‘ecosystem’ needed to support widespread DfMA in the Australian context, including the paradigm shift from building to manufacturing/assembly, the displacement of workers from onsite to offsite activity, and the expansion of interdisciplinary design and construct collaboration.

Extreme wind events caused damages and losses around the world every year. Windborne debris impact might create opening on building envelop, which would lead to the increase in internal pressure and result in roof being lift up and wall collapse. Some standards including Australia Wind Loading Code (AS/NZS 1170:2:2011, 2011) put forward design criteria to protect structures against windborne debris impacts. Structural insulated panel with Oriented Strand Board skin and expanded polystyrene core has been increasingly used in the building industry. Its capacity was found insufficient to resist the windborne debris impact in cyclonic areas defined in the Australian Wind Loading Code. Therefore, such panels need be strengthened for their applications in construction in cyclonic areas. In this study, impact resistance capacities of seven structural insulated panels strengthened with steel wire mesh and basalt fibre mesh were experimentally and numerically investigated. The impact resistance capacities were identified by comparing the damage mode, residual velocity and unpenetrated length of projectile after impact. Experimental results clearly demonstrated the enhancement of the impact resistance capacities of panels strengthened with steel wire mesh and basalt fibre mesh. Finite element model was developed in LS-DYNA to simulate the dynamic response of the structural insulated panels under windborne debris impact. The accuracy of the numerical model was validated with the testing data.

Ten days after the Newcastle, Australia earthquake of 28 December, 1989, the UK-based Earthquake Engineering Field Investigation Team (EEFIT) mounted a five day mission to the affected area. This paper presents the findings of the EEFIT investigation and subsequent follow up studies in relation to the extent of building damage and its distribution within the City of Newcastle and the surrounding urban area. Results are based on both detailed street surveys and general damage surveys, the former carried out in two areas, namely the heavily damaged suburban district of Hamilton (3km west of the city centre) and the Newcastle central business district. The findings of these surveys have provided valuable information on the vulnerability of building stock of types common to other parts of Australia, the UK and elsewhere, and hence form an important database for the accurate assessment of seismic risk to buildings in regions of low seismicity. This information will assist the development of realistic, economical seismic code provisions for building design and construction in low-risk areas. An important feature arising from the surveys and subsequent analytical studies of site response in the heavily damaged districts within the Hunter River alluvial basin is that, contrary to reports published by the Institution of Engineers, Australia amongst others, the areas of deep alluvial soil and fill do not correlate strongly with the more heavily damaged districts determined from post-earthquake assessments. Hence, suggestions that this form of site soil amplification effect played a major part in the distribution and extent of heavy damage in this earthquake are somewhat misleading for the future development of planning and design regulations. Furthermore, the results of site response analyses show that it is more likely to be the shallower soils near the border of the alluvial basin which tend to amplify bedrock ground motions generated by this type of earthquake.

Purpose – The purpose of this paper is to explore the implications of socially inclusive Building Information Modelling (BIM) library components. BIM requires and integrates many sets of predefined blocks or collection of attributes. Any one of the individual blocks can be replicated and/or stored in a block library for later reuse. However, few if any current block libraries contain or have access to the blocks that enable social inclusion. Design/methodology/approach – An action-based research methodology was used to design, develop and deploy three enabling blocks as part of a plan to develop a larger library of tools for BIM practitioners. The Enabling Block Library is an open access library of Australian code-compliant mobility elements published online. This paper discusses the design and development of the library components in detail, explaining how each of the three blocks was selected in our pilot evaluation and how each was identified; fact-checked; planned (designed); deployed (action); and then evaluated. Findings – The process and evaluation highlights that appropriate code-compliant design tools can support greater social inclusion aspects of a built environment project. These are tools that are relevant to the full spectrum of industry users of BIM, including designers, engineers and certifiers. Research limitations/implications – Because this paper documents the project while in an early launch phase, with a small number of launch blocks, the research results were limited in their ability to thoroughly measure industry or educational impact. However, the results showed how a socially inclusive BIM block library can be developed and why this is important, with literature supporting the potential of its dissemination to the design and construction industry. Originality/value – The paper applied action-based research methodology in the development, deployment and evaluation of exploratory BIM use to create more socially inclusive environments. It is of value because it facilitates designers creating the optimum of performance-based accessible environments, rather than the minimum “deemed to satisfy” Building Codes.

The development of a common Earthquake Loading Standard for Australia and New Zealand which has the potential for most countries in SE Asia is discussed in this paper. An historical perspective of earthquake loading standards in the two countries is introduced for background. In addition, two internationally recognised standards, Uniform Building Code (UBC) and Eurocode 8, covering earthquake loadings for areas of both low and high seismicity are presented. A seismic zoning scheme similar to the UBC approach is tentatively suggested for describing the seismic hazard of Australia and New Zealand. It is suggested that the requirements for design and detailing could vary from nominal tying together to capacity design procedures for the lowest and highest seismic zones respectively.

The vulnerability of urban environments in continental regions to earthquake forces was explicitly demonstrated in Australia's devastating Newcastle earthquake on December 28, 1989. This moderately-sized earthquake of Richter magnitude ML 5.6 (Moment magnitude M 5.3) claimed 13 lives, damaged more than 70,000 properties and left an estimated total loss of about $AU (1991) 4 billion. The need for an earthquake mitigation programme in Australia was thus clearly established. It is for this reason that a multidisciplinary approach involving seismology, geology, engineering, insurance, local government and emergency services is being followed to study this event and its consequences.
The earthquake source is defined as being on a thrust fault trending NW-SE dipping 75° to the NE, with a depth of focus at 11.5 km, source radius of 1.86 km, stress drop of at least 24 bars and a displacement along the rupture surface of at least 310 mm. The epicentre is located at 32.95°S, 151.61°E close to Boolaroo, about 15 km SW of the City of Newcastle, and with an epicentral error of about + 15 km. More than 100,000 observations from damage and felt reports are being analysed and integrated with the wide experiences gained in the rescue, recovery and renewal phases that have extended over the two years since the event.
The specific issue of the geotechnical aspects is of great importance. It is being considered from the view of urban geology (surface alluvial sediments), rather than from theoretical considerations, to explain the major extent of building damage on the alluvial areas, amplification and liquefaction. Apart from the immediate "causes" of damage, serious consideration is being given to the long-term effects which have resulted in the latent and recurrent defects to buildings. The engineering findings from the Newcastle earthquake are discussed in detail. While it is uneconomical and not necessary to design a structure to withstand the greatest likely earthquake without damage in Australia, the cost of providing strength to resist very high intensity loads must be weighed against the importance of the structure and probability of the earthquakes, particularly in areas such as this with relatively little known seismic histories. Lessons for local government authorities who had not previously considered seismic activity are addressed. Based on the response and recovery of the City of Newcastle, the lessons include the development of a recovery management plan, revision of building regulations and the requirements for hazard mitigation. Unfortunately, several misconceptions about some aspects of the consequences of this earthquake have arisen. These concern the limitations of some analyses, use of selected data sets rather than all the available data and apparent lack of understanding of complex, rather than singular, causal relationships. Implications for the engineering, insurance and possibly the legal professions need to be considered.
The potential to reduce losses in future earthquakes in Australia through an earthquake mitigation programme is now an achievable goal. The scenarios of such an event occurring at a different time or in a different city can be addressed, based on the Newcastle and other international experiences. Sufficient information is available to prepare the revised Australian earthquake loading code as a reliable and practical document for use by engineers. The consequences of the 1989 Newcastle earthquake have also captured the interest of researchers from many other continental areas of the Earth who must consider preparations for similar situations. All aspects of the study ultimately lead to the preparedness of urban communities to deal with such consequences with the assistance of emergency services agencies to minimize the social and economic traumas that will inevitably occur.

INTRODUCTION Our needs as social and familial beings change over the course of our lives; however, it has become common practice to build as though these needs remain static through time. The needs of a child, young adult, family, middle age and the elderly are dynamic between generations, and adding to these evolving life needs is the crisis of housing affordability. Three decades ago a house could cost 3–4 times an individual's annual income, today that cost is closer to 10–12 times. In response to these challenges, this article explores the concept of Sustainable Micro-Villages, providing insight into a new approach to energy-efficient housing with reference to our case-study project—Carwoola House. Sustainable Micro-Villages can be defined as a cluster of integrated dwellings, referred to here as Living Pods. Essentially a “single house” on a single site, these micro-villages can be comprised of two or more smaller buildings that provide private dwelling space for a single person, couples, couples with children, parents, elderly, friends and any combination of social groups. Living pods cluster around a natural garden setting, enhanced by water-harvesting, and are connected with covered, open or enclosed links depending on the climate of the site. The recent iterations of this type of dwelling also incorporate solar passive design, passive house and greenhouse technology. In Australia, new house designs are evaluated as part of an approvals process for their energy rating. 1 The Australian Building Code requires a minimum 6-star rating, ranging up to 10 stars for any new home to be built. A 6-star rating provides a good level of insulation and energy performance if built correctly, while 10 stars represent the highest level of energy performance and refers to a dwelling that needs no heating or cooling. Sustainable Micro-Villages consistently achieve an 8 to 10-star rating by combining Solar Passive Design principles (good orientation, thermal mass and thermal performance) and Passive House Technology (high thermally performing building with low air leakage, no thermal bridging, high performance glazing and heat recovery ventilation) in various combinations to suit the climate, context and budget.

Disproportionate rates of suicide in rural Australia in comparison to metropolitan areas pose a significant public health challenge. The dynamic interrelationship between mental and physical health, social determinants, and suicide in rural Australia is widely acknowledged. Advancement of this knowledge, however, remains hampered by a lack of adequate theory and methods to understand how these factors interact, and the translation of this knowledge into constructive strategies and solutions. This paper presents a protocol for generating a comprehensive dataset of suicide deaths and factors related to suicide in rural Australia, and for building a program of research to improve suicide prevention policy and practice to better address the social determinants of suicide in non-indigenous populations. The two-phased study will use a mixed-methods design informed by intersectionality theory. Phase One will extract, code, and analyse quantitative and qualitative data on suicide in regional and remote Australia from the National Coronial Information System (NCIS). Phase Two will analyse suicide prevention at three interrelated domains: policy, practice, and research, to examine alignment with evidence generated in Phase One. Findings from Phase One and Two will then be integrated to identify key points in suicide prevention policy and practice where action can be initiated.

Building standards and regulations have been around for a long time, and most historic structures were built in accordance with whatever codes existed at the time. However, as codes have changed (often in response to natural or human-caused disasters) these buildings have become progressively less compliant, making their continued occupation and use difficult without extensive and often damaging alterations to their significant spaces and fabric. In Australia, there have been considerable changes to standards over the past two hundred years to deal with apparent deficiencies in the codes exposed as a result of bushfires, earthquakes, cyclones and rising sea levels. Building regulations have also changed so as to deal in ever more detail with health and safety matters, as well as issues such as equitable access and energy efficiency. These changes have had an impact on historic buildings and structures, in the most extreme cases leading to loss of the building where owners anxious to redevelop can convince the authorities that preservation and upgrading to meet current standards will impose unreasonable economic hardship. In other cases, the insensitive and sometimes over-cautious application of codes (often to reduce the risk of future litigation or loss of insurance) leads to almost as much damage to the historic building as the upgrading work is intended to avoid if a disaster occurs. Conserving historic buildings while keeping them safely in active use requires a flexible and innovative approach to the regulations, as exemplified in the work of the Heritage Council of New South Wales Fire Access and Services Advisory Panel, of which the author was a foundation member.

Purpose The purpose of this paper is to present an analysis of common parameters in existing tools that provide guidance to carry out Whole Building Life Cycle Assessment (WBLCA) and proposes a new taxonomy, a catalogue of parameters, for the definition of the goal and scope (G&S) in WBLCA. Design/methodology/approach A content analysis approach is used to identify, code and analyze parameters in existing WBLCA tools. Finally, a catalogue of parameters is organized into a new taxonomy. Findings In total, 650 distinct parameter names related to the definition of G&S from 16 WBLCAs tools available in North America, Europe and Australia are identified. Building on the analysis of existing taxonomies, a new taxonomy of 54 parameters is proposed in order to describe the G&S of WBLCA. Research limitations/implications The analysis of parameters in WBLCA tools does not include Green Building Rating Systems and is only limited to tools available in English. Practical implications This research is crucial in life cycle assessment (LCA) method harmonization and to serve as a stepping stone to the identification and categorization of parameters that could contribute to WBLCA comparison necessary to meet current global carbon goals. Social implications The proposed taxonomy enables architecture, engineering and construction practitioners to contribute to current WBLCA practice. Originality/value A study of common parameters in existing tools contributes to identifying the type of data that is required to describe buildings and contribute to build a standardized framework for LCA reporting, which would facilitate consistency across future studies and can serve as a checklist for practitioners when conducting the G&S stage of WBLCA.

AbstractThis paper examines the recent NSW state government reassessment of the role of live music venues, and the gradual inclusion of live music within broader urban cultural policy across Australia. Focusing on Sydney, it maps the live music venue at the intersection of competing policy agendas, alternatively viewed as ‘vibrant’, exciting sites that represent a rejuvenated inner-city culture; or as sites of disruption, encouraging anti-social activity on the margins of legality (or sometimes both). The ‘rehabilitation’ of live music in the eyes of key government sectors was not simply a matter of ‘good’ cultural policy, but the result of a combination of many factors. The paper documents and analyses a six-year campaign by various stakeholders to implement noise, building code, late-night trading and liquor law reforms designed to ensure the survival of live performance venues and scenes.

Damaging earthquakes in Australia and other regions characterised by low seismicity are considered low probability but high consequence events. Uncertainties in modelling earthquake occurrence rates and ground motions for damaging earthquakes in these regions pose unique challenges to forecasting seismic hazard, including the use of this information as a reliable benchmark to improve seismic safety within our communities. Key challenges for assessing seismic hazards in these regions are explored, including: the completeness and continuity of earthquake catalogues; the identification and characterisation of neotectonic faults; the difficulties in characterising earthquake ground motions; the uncertainties in earthquake source modelling, and; the use of modern earthquake hazard information to support the development of future building provisions.
Geoscience Australia recently released its 2018 National Seismic Hazard Assessment (NSHA18). Results from the NSHA18 indicate significantly lower seismic hazard across almost all Australian localities at the 1/500 annual exceedance probability level relative to the factors adopted for the current Australian Standard AS1170.4–2007 (R2018). These new hazard estimates have challenged notions of seismic hazard in Australia in terms of the recurrence of damaging ground motions. This raises the question of whether current practices in probabilistic seismic hazard analysis (PSHA) deliver the outcomes required to protect communities and infrastructure assets in low-seismicity regions, such as Australia. This manuscript explores a range of measures that could be undertaken to update and modernise the Australian earthquake loading standard, in the context of these modern seismic hazard estimates, including the use of alternate ground-motion exceedance probabilities for assigning seismic demands for ordinary-use structures.
The estimation of seismic hazard at any location is an uncertain science, particularly in low-seismicity regions. However, as our knowledge of the physical characteristics of earthquakes improve, our estimates of the hazard will converge more closely to the actual – but unknowable – (time independent) hazard. Understanding the uncertainties in the estimation of seismic hazard is also of key importance, and new software and approaches allow hazard modellers to better understand and quantify this uncertainty. It is therefore prudent to regularly update the estimates of the seismic demands in our building codes using the best available evidence-based methods and models.

There has been a call for the construction industry to become more energy efficient in its planning and activities, to reduce greenhouse gas emissions to help combat climate change. The Australian Building Codes Board has implemented ‘Energy Efficiency’ standards through the National Construction Codes to direct the industry towards net zero emissions goals. However, the Board has maintained a focus on operational flows considerations despite this only being a part of the total expenditure in a building lifecycle. Embodied flows, the energy output, and emissions from harvesting, manufacturing, transporting, and manufacturing materials for a building have not been included as a part of the current standards despite their growing share in the outputs of construction. A qualitative document analysis using data from academic articles and industry publications was performed to identify the context in embodied policy development. Findings reveal an abundance of different legislations and initiatives globally, recommending techniques that may effectively achieve embodied flow reductions. The results highlighted that Australia needs to capitalize on the potential reductions in overall energy and emissions from construction. Other regions have provided a strategic and legislative basis for the industry to emulate.

This study aimed to describe the epidemiological characteristics, the occupational context, and the cost of hospitalised work-related traumatic spinal injuries, across New South Wales, Australia. A record-linkage study of hospitalised cases of work-related spinal injury (ICD10-AM code U73.0 or workers compensation) was conducted. Study period 2013–2016. Eight hundred and twenty-four individuals sustained work-related spinal injuries; 86.2% of whom were males and had a mean age of 46.6 years. Falls led to 50% of the injuries; predominantly falls from building/structures, ladders or between levels. Falls occurred predominantly in the construction industry (78%). Transport crashes caused 31% of injuries and 24% in heavy vehicles. Half of all the transport injuries occurred ‘off road’. The external cause was coded as ‘non-specific work activity’ in 44.5% of cases; missing in 11.5%. Acute care bed days numbered at 13,302; total cost $19,500,000. High numbers of work-related spinal injuries occurred in the construction industry; particularly falling from a height. Off-road transport-related injuries were significant and likely unaddressed by ‘on-road’ prevention policies. Medical record documentation was insufficient in injury mechanism and context specificity. Workers in the construction industry or those using vehicles off-road were at high risk of spinal injury, suggesting inefficient systems approaches or ineffective prevention policies. Reducing the use of non-specific external cause codes in patients’ medical records would improve the measurement of policy effectiveness.

Objective. A substantial literature engaging with the directions and experiences of stakeholders involved in interprofessional health education exists at the international level, yet almost nothing has been published that documents and analyses the Australian experience. Accordingly, this study aimed to scope the experiences of key stakeholders in health and higher education in relation to the development of interprofessional practice capabilities in health graduates in Australia. Methods. Twenty-seven semi-structured interviews and two focus groups of key stakeholders involved in the development and delivery of interprofessional health education in Australian higher education were undertaken. Interview data were coded to identify categories that were organised into key themes, according to principles of thematic analysis. Results. Three themes were identified: the need for common ground between health and higher education, constraints and enablers in current practice, and the need for research to establish an evidence base. Five directions for national development were also identified. Conclusions. The study identified a range of interconnected changes that will be required to successfully mainstream interprofessional education within Australia, in particular, the importance of addressing issues of culture change and the need for a nationally coordinated and research informed approach. These findings reiterate those found in the international literature. What is known about the topic? Interprofessional health education (IPE) and practice (IPP) capabilities are central to the delivery of health services that are safer, more effective, patient-centred and sustainable. The case for an interprofessionally capable health workforce is therefore strongly argued and well accepted in the international literature. The task of building a nationally coherent approach to IPE within health professional curricula, however, is complex and challenging, and there is almost no literature in this area presenting an Australian perspective. What does this paper add? This paper presents perspectives from key stakeholders in the Australian health and higher education sectors on the challenges associated with implementing and sustaining IPE to foster IPP across all health professions. It identifies several policy, cultural, institutional and funding changes that will be required to locate IPE as a central rather than peripheral education activity. What are the implications for practitioners? The study points to changes that will be required to build an Australian health workforce with increased levels of IPP capability. It highlights the importance of recognising and addressing culture change as a central part of embedding and sustaining IPE and IPP. Additionally it foregrounds for governments, higher education and health practitioners the importance of addressing the development of IPE and IPP as a multi-dimensional task, that will require a national and research informed approach to build momentum and scale.

This paper provides an overview and the results of a recent experimental study testing the lateral cyclic displacement capacity of limited ductile reinforced concrete (RC) walls. The experimental program included one monolithic cast in-situ rectangular wall specimen and one monolithic cast in-situ box-shaped building core specimen. The specimens were tested using the MAST system at Swinburne University of Technology. They were tested under cyclic in-plane unidirectional lateral load with a shear-span ratio of 6.5. The specimens were detailed to best match typical RC construction practices in regions of lower seismicity, e.g. Australia, which generally results in a ‘limited ductile’ classification to the Australian earthquake loading code. This reinforcement detailing consisted of constant-spaced horizontal and vertical bars on each face of the wall and lap splices of the vertical reinforcement at the base of the wall in the plastic hinge region. The rectangular wall and building core specimens both achieved a relatively good lateral displacement capacity given the limited ductile reinforcement detailing adopted. The lap splice at the base of the specimens resulted in a somewhat different post-yield curvature distribution being developed. Rather than a typical plastic hinge with distributed cracks being developed, a ‘two crack’ plastic hinge was formed. This consisted of one major crack at the base of the wall and another at the top of the lap splice, with only hairline cracks developing between these two major cracks. The majority of the plastic rotation was concentrated in each of these two major cracks.

The article reports on a study using grounded theory methodology to track the contexts in which Australian parliamentarians used the expressions 'press freedom' and 'freedom of press' over the ten years from 1994 to 2004. It uses Parliamentry Hansard records to identify the speeches in which discussions of press freedom arose. Interestingly, the terms were used by members of the House of Representativies or Senate in just 78 speeches out of more than 180,000 over that decade. Those usages have been coded to develop a theory about the interface between press freedom and the parliament. This article reports just one aspect of the findings from the larger study—the way parliamentarians have contrasted the value of press freedom in Australia with press freedom in other countries. It is one step towards building a broader theory of press freedom in the Australian parliamentary context.

Modern design, construction innovation and maintenance issues have been extensively utilised for composite steel-concrete building structures in Australia. This paper provides an overview of the design codes, innovative construction applications and maintenance issues for steel-concrete composite members in Australia. The paper initially provides an overview of the various codes of practice for steel-concrete composite members in Australia. In identifying construction innovation significant projects to adopt composite construction techniques are considered. Many of these projects have found that the national codes of practice have been lacking in guidance. This has thus been the focal point for much of the research into the area of steel-concrete composite members over the last two decades. The paper concludes with research that is currently being carried out which considers materials and solutions in composite structural forms which promote the concepts of sustainability and will inevitably be prominent in improved maintenance of steel structures in the future.

This paper presents seismic site classification practices for urban centres in Australia, China, and India with special emphasis on their suitability for shallow soil sites. The geotechnical aspects of seismic site classifications play a critical role in the development of site response spectra, which is the basis for the seismic design of new structures and seismic assessment of existing structures. Seismic site classifications have used weighted average shear wave velocity of top 30 m soil layers, following the recommendations of National Earthquake Hazards Reduction Program (NEHRP) or International Building Code (IBC) site classification system. The site classification system is based on the studies carried out in the United States where soil layer may extend up to several hundred meters before reaching any distinct soil-bedrock interface. Most of the urban centers in Australia, China, and India are located on distinct bedrocks within few meter depth of soil deposits. For such shallow depth soil sites, NEHRP or IBC site classification system is not suitable. A new site classification based on average soil thickness, shear wave velocity up to engineering bedrock is proposed. The study shows that spectral value and amplification ratio estimated from site response study considering top 30 m soil layers are different from those determined considering soil thickness up to engineering bedrock.

School toilets have been identified by sexuality and gender diverse (SGD) students as the least safe spaces in educational institutions. They are sites of verbal, physical and sexual victimisation. Providing gender-neutral toilets in primary and secondary schools may reduce the bullying and victimisation of SGD students, particularly those who are transgender or gender-diverse. This study explored factors influencing the inclusion of gender-neutral toilets in primary and secondary schools in Western Australia. Thirty-four interviews were conducted from May to December 2020 with policy makers or practitioners (n = 22) and school staff (n = 12) in Perth, Western Australia. Interviews were conducted online and face-to-face using semi-structured interview guides. A thematic analysis of the cross-sectional qualitative data was undertaken. School staff, policy makers, and practitioners identified school toilets as sites of bullying and victimisation of SGD youth and expressed support for gender-neutral toilets as an anti-bullying strategy. Perceived barriers to introducing gender-neutral toilets in schools included financial and spatial costs, building code compliance constraints, resistance from parents and students, privacy and confidentiality concerns, and cultural appropriateness. Including gender-neutral toilets in schools may reduce school-based bullying and victimisation, and improve the mental and physical health of SGD youth.

Structural steel frames exhibit significantly geometric and material nonlinearities which can be captured using the second-order inelastic analysis, also known as advanced analysis. Current specifications of most modern steel design codes, e.g. American code AISC360, European code EC3, Chinese code GB50017 and Australian code AS4100 permit the use of advanced analysis methods for the direct design of steel structures to avoid tedious member capacity checks. In the past three decades, a huge number of advanced analysis and modeling methods have been developed to predict the behavior of steel and composite frames. This paper presents a comprehensive review of their developments, which focus on beam-column elements with close attention to the way to capture geometric and material nonlinearity effects. A brief outline of analysis methods and analysis tools for frames was presented in the initial part of the paper. This was followed by a discussion on the development of displacement-based, force-based and mixed beam elements with distributed plasticity and concentrated plasticity models. The modeling of frames subjected to fire and explosion was also discussed. Finally, a review of the beam-column models for composite structures including concrete-filled steel tubular (CFST) columns, composite beams and composite frames was presented.

AbstractCodification of tort law is a rare phenomenon in the common law world. However, building on earlier precedents, in the early 2000s, Australian jurisdictions embarked on a project of placing important general principles of negligence law into legislation. This article considers these provisions and argues that they can be considered as an attempt to codify certain parts of the law of tort. Both the process by which this codification took place, and the contents of the ‘codes’, provide interesting comparative material for civilian jurisdictions with codified tort law as well as for common law systems.

Rainwater tanks are increasingly being implemented as part of the integrated urban water management paradigm where all sources of water, including potable, stormwater and recycled, are considered eligible to contribute to the urban water supply. Over the last decade or so, there has been a rapid uptake of rainwater tank systems in urban areas, especially in Australian cities, encouraged through financial incentives, but more importantly, from change in residential building codes effectively mandating the installation of rainwater tanks. Homes with rainwater tanks in Australian cities have increased from 15% to 28% over six years to 2013. These building codes specify certain rainwater tank specifications to achieve a stated rainwater use, and hence potable water savings. These specifications include minimum rainwater tank size, minimum connected roof area, plumbing for internal supply for toilets and washing machines, and external supply for garden watering. These expected potable water savings from households are often factored into regional strategic water planning objectives. Hence if rainwater tanks do not deliver the expected saving due to sub-standard installation and/or poor maintenance, it will have an adverse impact on the regional water plan in the longer term. In this paper, a methodology to assess the effectiveness of a government rainwater tank policy in achieving predicted potable water savings is described and illustrated with a case study from South East Queensland, Australia. It is anticipated that water professionals across the globe should be able to use the same methodology to assess the effectiveness of similar rainwater policies, or indeed any other distributed water saving policy, in their local planning communities.

The current paper presents an application of an alternative probabilistic risk assessment methodology that incorporates technical, human, and organizational risks (T-H-O-Risk) using Bayesian network (BN) and system dynamics (SD) modelling. Seven case studies demonstrate the application of this holistic approach to the designs of high-rise residential buildings. An incremental risk approach allows for quantification of the impact of human and organizational errors (HOEs) on different fire safety systems. The active systems considered are sprinklers, building occupant warning systems, smoke detectors, and smoke control systems. The paper presents detailed results from T-H-O-Risk modelling for HOEs and risk variations over time utilizing the SD modelling to compare risk acceptance in the seven case studies located in Australia, New Zealand, Hong Kong, Singapore, and UK. Results indicate that HOEs impact risks in active systems up to ~33%. Large variations are observed in the reliability of active systems due to HOEs over time. SD results indicate that a small behavioral change in ’risk perception’ of a building management team can lead to a very large risk to life variations over time through the self-reinforcing feedback loops. The quantification of difference in expected risk to life due to technical, human, and organizational risks for seven buildings for each of 16 trial designs is a novel aspect of this study. The research is an important contribution to the development of the next generation building codes and risk assessment methods.

Purpose: Recently, public health networks in Australia have introduced clinical research specialists to drive research in the allied health professions by helping clinical social workers engage in research. This study examines the benefits of a flexible research program for busy social work novice and experienced clinicians. Methods: Thirty hospital-based social workers were allocated a total of 12 research projects. Participants were given a mixed-methods survey both pre and post an education program with 17 responses for the presurvey and 12 responses postsurvey. The responses were coded via thematic analysis. Results: Despite initial clinician apprehension, the majority of participants found it beneficial. In the busy hospital context, support that was valued included simplified information and regular mentorship and training. Discussion: The role of a research lead with management support is pivotal in promoting a positive research culture and active research. However, clinical demand still reduces capacity to engage in research.

The home-sharing platform, Airbnb, is disrupting the social and spatial dynamics of cities. While there is a growing body of literature examining the effects of Airbnb on housing supply in first-world, urban environments, impacts on dwellings and dwelling typologies remain underexplored. This research paper investigates the implications of “on-demand domesticity” in Australia’s second largest city, Melbourne, where the uptake of Airbnb has been enthusiastic, rapid, and unregulated. In contrast to Airbnb’s opportunistic use of existing housing stock in other global cities, the rise of short-term holiday rentals and the construction of new homes in Melbourne has been more symbiotic, perpetuating, and even driving housing models—with some confronting results. This paper highlights the challenges and opportunities that Airbnb presents for the domestic landscape of Melbourne, exposing loopholes and grey areas in the planning and building codes which have enabled peculiar domestic mutations to spring up in the city’s suburbs, catering exclusively to the sharing economy. Through an analysis of publically available spatial data, including GIS, architectural drawings, planning documents, and building and planning codes, this paper explores the spatial and ethical implications of this urban phenomenon. Ultimately arguing that the sharing economy may benefit from a spatial response if it presents a spatial problem, this paper proposes that strategic planning could assist in recalibrating and subverting the effects of global disruption in favor of local interests. Such a framework could limit the pernicious effects of Airbnb, while stimulating activity in areas in need of rejuvenation, representing a more nuanced, context-specific approach to policy and governance.

Structural insulated panel (SIP) is considered as a green panel in construction industry because of the low thermal conductivity of the sandwiched EPS core (i.e extended polystyrene). It is a lightweight composite structure and is widely used in commercial, industrial and residential buildings to construct the building envelop including roof and wall. The windborne debris driven by cyclone or hurricane usually imposes intensive localized impact on the structural panel, which might create opening to the structure. The opening on the building envelope might cause internal pressures increase and result in substantial damage to the building structures, such as roof lifting up and wall collapse. The Australian Wind Loading Code (version 2011) [1] requires structural panels to resist projectile debris impact at a velocity equal to 40% of the wind speed, which could be more than 40 m/s in the tropical area with the wind speed more than 100m/s. In this study, two kinds of SIP under projectile debris impact were investigated, i.e. “Corrolink” and “Double-corrolink” composite panels shown in Fig. 1. Laboratory tests were carried out by using pneumatic cannon testing system to investigate the dynamic response of composite panels subjected to wooden projectile impacts. The failure modes were observed. The structural dynamic responses were also examined quantitatively based on the deformation and strain time histories measured in the tests. The penetration resistance capacity of panels subjected to windborne debris impact was assessed.Fig. 1 Schematic diagrams (L) Corrolink panel; (R) Double-corrolink panel [2]

A number of extreme value analysis techniques are utilised to predict basic design gust wind speeds for Fiji, which lies in a tropical cyclone prone region. The study shows that a number of modern methods tend to highly under-predict extreme wind speeds in regions of Fiji severely affected by tropical cyclones, although their skills improve in less severely affected regions. The reference for comparison was Dorman?s method, which has been previously used as a guidance for development of Region D wind speeds in the Australian wind loading code ? the AS1170.2-1989. In the case of Fiji, this study recommends the AS1170.2-1989 Region C provisions for Suva and the eastern coasts of the main island of Viti Levu only, and the AS1170.2-1989 Region D provisions elsewhere. This is significantly different to the provisions of the current National Building Code of Fiji (1990) which allow for the use of AS1170.2-1989 Region C provisions for all of Fiji. This difference is attributed to differences in the frequency and intensity of tropical cyclones visiting Fiji as compared with those for Australian Region C.
