Purpose: The business benefits envisaged for BIM represent the main criteria for decision-making about BIM implementation – or shy away from BIM. Despite the significance, traditional evaluation techniques have difficulty to capture "the true value" of BIM from multiple levels and dimensions – as an effective evaluation method is supposed to. This study aims to identify the significant factors that affect BIM return on investment (ROI), develop an integrated model for companies and examine the influence of intangible returning factors of BIM on the rate of BIM implementation. Design/methodology/approach: A cluster sampling technique was used; 92 questionnaires completed by Australian architecture, engineering and construction small- and medium-sized enterprises (SMEs) provided the basis to identify and analyse the key measurable returning factors, value drivers and strategic benefits associated with BIM ROI. Findings: Applying the PLS-SEM technique, findings reveal that a lack of reliable quantification methods for the ROI factors associated with BIM significantly affects the organisation's commitments to implement BIM. In essence, the failure to adequately identify and assess these benefits could result in the system not being appropriately implemented and supported by executive sponsors, who give priority to hard and tangible ROI measurements. Practical implications: The outcome of this study would be of direct appeal to policymakers, industry professionals and the academic community alike, in providing data-informed insight into the intersection between the implementation of BIM and the concept of ROI. Findings would provide a springboard for further research into using ROI factors to increase BIM implementation. Though the findings are directly applicable and contextualised for Australia, they provide lessons and offer a blueprint for similar studies in other countries and settings. That is, regardless of the context, findings raise awareness and provide a point of reference for the quantification of intangible returning factors rather than the tangible returning factors, as one of the first studies in its kind. Originality/value: The study provides original insight in drawing attention to an untapped area for research in BIM implementation, namely BIM ROI. Apart from raising awareness around BIM ROI, the study is novel in providing a quantified model that establishes the links and level of impacts of various factors associated with BIM ROI. Findings of this study, particularly add value to the body of knowledge related to the business implications associated with BIM implementation in the context of Australian SMEs, while providing lessons for other countries and settings.

The most significant current technological trend is digitization, the impacts of which will be faced by all levels of society. This paper addresses how the Australian construction industry has kept up with the pace of digitization compared with other industries in Australia. The data is drawn mainly from the national accounts hosted by the Australian Bureau of Statistics, within the time period of 1995–2015. Construction has developed into one of the most important industries in Australia. Together with mining and the financial and insurance sector, it has contributed to a significant gross added value (GVA) in the economy. The construction industry has invested around 1% or less in information and communication technologies (ICT) as their share of GVA; however, it has invested about 15% in ICT of their total investments (gross fixed capital formation). Among the selected industries, construction's labour productivity measured by GVA per hour was the third highest, despite low level of investments in digitization. The observed correlation between ICT investments and productivity is weak when using industry level data from the national accounts. Any big leap towards digitization is not recognised for the construction industry; rather there appears to be steady acceptance of the technology. [ABSTRACT FROM AUTHOR]

Concrete is the second most used material after water and the production of cement is responsible for 5–8% of global carbon dioxide emissions. The development of low-carbon concretes is pursued worldwide to help the construction industry make its contribution to decarbonising the built environment and achieving carbon reduction targets agreed under the Paris Climate Agreement. However, there is uncertainty around the actual amount of greenhouse gas emissions that can be avoided by employing alternative types of concrete. This study quantifies the carbon footprint intensities of Australian cement and concrete production, including ordinary Portland cement, standard ordinary Portland cement concrete, blended cement-based concrete and geopolymer concrete production. For the first time, an input-output based hybrid life-cycle assessment method is used for these products. The main goal of this paper is therefore to make a methodological comparison between process-based and hybrid life cycle assessment using the Australian cement and concrete production as a case study. A comparison with published results from process-based life-cycle inventories as well as a decomposition of results into product categories is provided. The hybrid life cycle assessment resulted in higher greenhouse gas emissions for ordinary Portland cement and all types of concrete due to the methodology incorporating an economy-wide system boundary, which includes the emissions from upstream processes. For geopolymer concrete in particular, the results were also dependent on the method applied for allocating greenhouse gas emissions from fly ash and slag. The findings from this study are likely to inform the development of strategies and policies aimed at greenhouse gas reduction in the cement and concrete industries. [ABSTRACT FROM AUTHOR]

The last decades have witnessed a rapid development of green building developments at a global scale, as a measure to deal with various challenges related to climate change especially environmental issues. Australia is no exception. It is not unusual that extra resources such as cost are required for developing green buildings compared to conventional buildings. To justify extra upfront resources required for green building developments, a variety of tools have been developed such as life cycle assessment and life cycle costing. These two tools have been used in some projects in order to evaluate the cost and benefits of green buildings from a life cycle perspective. However, the uptake of life cycle assessment and life cycle costing are generally slow in the construction industry. This paper presents a critical review of green building evaluation from life cycle perspective. In particular, the use of life cycle assessment and life cycle costing in green building evaluation in Australia is reviewed. Knowledge gap is presented and future research agenda is proposed.

The increasing awareness of the undesirable environmental impact of cement-based products has led to rethinking earth construction within the digitally mechanised framework of Industry 4.0. The attempts to mechanise earth construction started nearly a decade ago, yet, the past four years have seen a surge in the intensity of research on the advanced manufacturing of earth construction. Additive manufacturing of clay-rich soil, like in cob and adobe methods, has been attracting the primary attention, while on the contrary, considerably limited research has been conducted to mechanise other methods such as rammed earth. This paper collected, reviewed, and analysed the state-of-the-art research on the advanced manufacturing of rammed earth construction, with a focus on process design aspects and machine development. Two case studies of recent digitally manufactured rammed earth projects in Australia and Switzerland were comprehensively analysed to provide a realistic feasibility assessment of the potential and technical challenges. The insights from this research provide a holistic and tangible roadmap to the digital manufacturing of rammed earth construction, which aids in making it more desirable and capable of meeting contemporary demands of the architecture and construction of Industry 4.0. • State-of-the-art advanced manufacturing methods for rammed earth construction are critically reviewed. • Two case studies of digitally manufactured rammed earth projects in Australia and Switzerland are comprehensively analysed. • Potential and challenges of advanced manufacturing for rammed earth construction are discussed. • Information for enhanced utilisation of digital techniques in rammed earth construction is provided.

Purpose: The burden of health and safety related issues emanating from the modern workplace is overwhelming. Although the prevailing statistics found in the literature show that victims of workplace fatalities and injuries are higher in developing countries and transition economies, there is a very limited understanding of the causal factors that may correspond to the continuous increase in the occupational exposure of employees to various fatalities and injuries. The purpose of this study was to review the literature on occupational safety of workers with the objective of highlighting the major causal factors of workplace injuries and fatalities from a multi-regional perspective, particularly on job-contexts with highest safety and health related hazards. Methodology: A systematic review of the literature was conducted on 73 empirical studies in the regions of Europe, Africa, the Middle East, Asia, Australia, and the Americas (the US & Canada). Findings: The results showed that the highest number of injuries and fatalities were mostly found in the construction industry. It further emerged that most of the studies were centered in developing countries within Africa and Asia. Other results and recommendations were discussed for each region. Value: The findings from this study have the potential to expose the regional dynamics in relation to safety in the workplace. This study also addresses the main areas of concern for stakeholders to promote organizational development and safety culture. [ABSTRACT FROM AUTHOR]

Underground utilities pose a hazard during excavation works. One-call services are available to prevent strikes by providing relevant drawings to contractors, such as Dial Before You Dig in Australia. Even with this service and many other technologies, incidents keep occurring at an alarming rate. The research team developed a plan to observe relevant incidents occurring at multiple sites in Melbourne. Thirty cases of service strikes were detected over a 2-year period and the data showed the existence of common causes related to proactiveness in operational management. This includes errors in the use of current tools such as geographic information systems, which need to correctly show the most up-to-date buried infrastructure to be effective. This research also highlighted the need for procedures to be followed that involved having assets marked out on site and proved through non-destructive digging prior to excavation. Two practical scenarios were used to verify the research findings. [ABSTRACT FROM AUTHOR]

There is urgent need to consider energy consumption when measuring total-factor productivity in the construction industry. This paper adopts the Malmquist index method to investigate the factors affecting the energy productivity of the Australian construction industry and compares them with those decomposed from the total-factor productivity. An input-oriented distance function and a contemporaneous benchmark technology are employed to develop the data envelopment analysis models. The Malmquist productivity index is decomposed into the technological change, pure technical efficiency change and activity effect to gain comprehensive insights into changes of construction productivity in the Australian states and territories over the past two decades. Research results show that both energy productivity and total-factor productivity improved in Australia, particularly related to technological development. The pure technical efficiency and activity indices changed slightly over time or across regions. This study demonstrates that there exists a linkage between energy productivity and total-factor productivity through their technological and technical efficiency changes. The Australian construction industry could enhance these two productivities by introducing advanced technologies and implementing them efficiently. [ABSTRACT FROM AUTHOR]

Insolvency has become endemic in the Australian construction industry. The scale of the problem has reached such proportions that both the NSW Parliament and the Senate have, in recent times, commissioned inquiries into construction insolvency. This paper aims to identify the reasons as to why the construction industry is so susceptible to insolvency, evaluate the effectiveness of any existing insolvency protection measures available to construction firms, and to identify proposed future measures to address the factors causing construction insolvency. The results of a questionnaire survey designed to discover the extent of the construction insolvency problem, as well as building contractors' views with respect to the causes and regulation of construction insolvency, in South Australia are presented. The research found that there is an appetite amongst building contractors for the introduction of further regulation to address construction insolvency. Further, although the research found underbidding to be the biggest contributory factor towards construction insolvency, it appears to be the most difficult factor to address through regulation which explains the paucity of recommendations which directly address underbidding emanating from the Senate inquiry in 2015.

To be sustainable in energy usage in the future, there are two aspects that need to be considered: the energy supply or generation and the consumption side, including the closely linked construction and building industries which consume a large amount of energy. Essential requirements for energy efficiency are to produce less greenhouse gas emissions and to rely more on renewable energy sources for future sustainability. Policies for mitigation of the environment impact are having effects on both the supply and demand. While the former requires more alternate sources in smart grids and improved technologies for carbon capture and storage, the latter involves the reduction of energy wastes and greenhouse gas (GHG) emissions as prerequisites to green certification within the construction and building sector. Thus, access to sustainable, affordable, and secure energy is one of the major global strategic priorities to maintain and improve public health, sustain economic growth, and mitigate the effects of climate change. Toward this goal, many countries, including Australia, are investing in clean, efficient, reliable energy systems for a prosperous and environmentally sustainable future. Hence, exploring various options to ensure energy security by diversification of energy sources is an important step in meeting the future requirements and delivering clean energy to different industry sectors. This paper discusses options to manage the use of energy sources in the power generation and construction industries. Options for mitigation of environmental impact and for achievement of sustainable energy usage, such as building design with BIM, are discussed. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to investigate the effect of Australian construction firms' cooperative behavior on reverse logistics outsourcing performance (RLOP). Design/methodology/approach: To achieve the aim, a questionnaire survey was conducted to collect data from construction firms in Australia. Following this, the study used Partial Least Squares Structural Equation Modeling (PLS-SEM) to analyze 173 responses for testing seven hypotheses that are related to the positive effects of cooperative behavior on RLOP. Findings: The results indicate that three dimensions of customer cooperative behavior (cooperation, commitment and planning) positively influence RLOP in different ways. Cooperation only directly affects RLOP while planning only has an indirect influence on RLOP. Commitment affects RLOP both directly and indirectly. Originality/value: This is the first study examining empirically antecedents of RLOP in the construction industry. Additionally, it reveals the mediating role of cooperation. Cooperation fully mediates the relationship between planning and RLOP, and partially mediates the relationship between commitment and RLOP. [ABSTRACT FROM AUTHOR]

The Australian prefabricated construction market has been developing rapidly in recent years. New prefabrication-related technologies, materials, systems and services are also emerging in the current Australian market. Although some studies have been undertaken to explore the benefits and challenges of implementing prefabrication in Australia over the past 15 years, they do not reflect the recent changes in the industry. Therefore, this study aims to fill this gap and identify the major changes in the current Australian prefabricated construction industry from industrial perceptions. Through literature reviews and industry interviews, factors reflecting major changes in the current Australian prefabricated construction, including prefabrication industry development, emerging benefits and challenges, were identified and discussed in this study. The challenges identified from interviews were classified into eight aspects related to feasibility, design, manufacturing, transportation, on-site construction, standardisation, skills and knowledge, finance and market. Furthermore, 21 recommendations and related key responsible parties were identified to tackle these challenges. The findings will provide useful references for various stakeholders to have a better understanding of the current prefabrication industry development in the Australian context and re-think how to adapt to future changes for the uptake of prefabricated construction in Australia.

The construction industry in many countries is faced with skill shortages. Attracting more female workers in the male-dominated construction industry can help alleviate this issue. However, perceived concerns of increased or specific Occupational Health and Safety (OHS) risks for females could be a significant deterrent. Due to their marginal representation in various trade roles, the overall analyses of OHS incident data fail to capture the specific OHS concerns that apply to female construction workers. This study presents an empirical analyses of workers' compensation data obtained from Safe Work Australia for 12 years (2008–2019) to investigate specific OHS risks for female construction workers. The annual average incident trend does not present a steady increase or decrease in permanent and temporary incapacities among female construction workers. Moreover, the incident number, severity, and employment data together reveal that female workers in both professional and manual or trade occupations have lower incident rates than their male counterparts. However, the findings also reveal that: (1) building and plumbing women laborers and earthmoving plant operators are more prone to injuries that result in permanent incapacities; (2) fractures, soft tissue injuries, deafness, anxiety, stress, and depression lead to permanent incapacities among female workers; and (3) falls on the same level, muscular stress while handling objects, long-term exposure to sounds, work pressure, workplace harassment, and bullying result in permanently incapacitating injuries. The study also noted the differences in the occupations, mechanisms of incidents, and injury types that contribute to most incidents among male and female construction workers. The findings of this study can help training providers, construction organizations, and practitioners identify specific OHS concerns for developing more comprehensive OHS management plans, training, and awareness programs for female construction workers. The existing OHS management and training programs should be remodeled accordingly to incorporate gender-specific OHS risks and injury mechanisms rather than a one-size-fits-all approach. Clients, specifically in public projects, may stipulate that the contractor provides gender-specific OHS management plans to ensure the OHS of workers of different genders. It is vital to educate female construction workers from various occupations about specific OHS risks, incident mechanisms, and preventive actions. The higher occurrence of musculoskeletal disorders due to handling objects demands redesigning work processes to reduce female construction workers' manual handling of objects. The present study also shows that work pressure, anxiety, and depression are prevalent among female construction workers, taxing their mental health and causing permanent incapacities. The psychosocial conditions and work pressure resulting from these health conditions must be managed at both the project and organizational levels to attract and retain more female workers in the construction industry. Such efforts are expected to improve female representation and their OHS, well-being, and job satisfaction and reduce skill shortages in the long run. [ABSTRACT FROM AUTHOR]

The last 30 years has seen significant developments in the Australian housing sector for people with disabilities. Despite much change in the sector, and advancements in disability services, the range of current supported housing options for younger Australian adults with a neurological disability remains vastly under-developed. This is despite a widely accepted and endorsed recognition that, as is the general population, people with all forms of disability have a right to housing of their choice. This paper presents a timely critique of the key actions made by the Australian disability and housing sectors and subsequently proposes a more informed approach to supported housing design and development: one that is based on a comprehensive understanding of consumer housing priorities and preferences, and is conducive to a person’s biopsychosocial health.

Building Information Modelling (BIM) is seen as a panacea to many of the ills confronting the Architectural, Engineering and Construction (AEC) sector. In spite of its well documented benefits the widespread integration of BIM into the project lifecycle is yet to occur. One commonly identified barrier to BIM adoption is the perceived legal risks associated with its integration, coupled with the need for implementation in a collaborative environment. Many existing standardised contracts used in the Australian AEC industry were drafted before the emergence of BIM. As BIM continues to become ingrained in the delivery process the shortcomings of these existing contracts have become apparent. This paper reports on a study that reviewed and consolidated the contractual and legal concerns associated with BIM implementation. The findings of the review were used to conduct a qualitative content analysis of the GC21 2nd edition, an Australian standardised construction contract, to identify possible changes to facilitate the implementation of BIM in a collaborative environment. The findings identified a number of changes including the need to adopt a collaborative contract structure with equitable risk and reward mechanisms, recognition of the model as a contract document and the need for standardisation of communication/information exchange.

There have been numerous concerns about the lack of productivity improvement in the New Zealand construction industry. The aim of this paper, therefore, is to determine the main drivers of productivity in the industry. The research used is a two-staged data envelopment analysis approach to achieve the aim. In terms of improvements to the productivity of construction in New Zealand, the study found that although there is a potential for gains through the greater use of research and development, apprentice training and degree education, as well as the consolidation of some building companies, there will be some limits to the gains that might be made. One main implication of the findings of the study, therefore, is that a renewed focus on education and skills training should be a priority of companies and policy makers in New Zealand.

Estimates of the size and change in the Australian construction industry shadow economy value over time are provided and applied as a quality adjustment to Australian construction industry productivity growth from 1985 to 2012. The results indicate that the Australian construction industry shadow economy is growing and that by adjusting for the shadow economy, distortion is removed from construction industry productivity growth estimates. The findings create significant scope for future research into the estimation and the effect of shadow economic activity on productivity growth, not just in Australia but in other countries as well.

The aim of the article is to identify the factors that prevented British aircraft manufacturers from investing in Australia in the second half of the 1930s, a period when rearmament was creating demand for aircraft. The article looks at several unsuccessful proposals by British manufacturers to establish factories in Australia to build aircraft in the late 1930s, with additional attention being given to one proposal in particular. There is evidence that the Australian Government favoured the creation of an Australian‐owned industry building aircraft under licence to foreign manufacturers, and it was this factor that largely deterred British investors.

The social dimensions of sustainability's three bottom lines are often overlooked in the construction industry. This is despite attempts to find optimal trade-offs between economic growth, environmental impacts, human health and well-being, as well as social considerations. This study reviews the literature on social sustainability (SS) within the construction arena, identifies research gaps and proposes a forward-looking research agenda. This critical review employes the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' (PRISMA) technique to retrieve secondary data on SS from available academic, government and industry documents. The literature analysis focuses on seven themes: (1) definition of SS, (2) the theoretical dimensions of SS, (3) primary stakeholders, (4) policy and guidelines, (5) major SS performance indicators, (6) barriers to SS uptake in the construction industry, and (7) SS drivers in the construction industry. The review identifies primary stakeholders and proposes a list of assessment criteria that can be used by the construction industry in measuring progress towards SS. The study proposes a conceptual model that maps out key stakeholders, the major barriers, and enablers of SS in construction projects. The findings will support the development of SS guidelines specific to the construction industry in Australia as well as overseas. [ABSTRACT FROM AUTHOR]

Transactional and transformational safety leadership have been repeatedly found to be important for safety. Yet how transactional and transformational leadership behaviours are most effectively demonstrated can be dependent on the context and industry. Using an ethnographic approach, supervisor safety leadership was explored across eleven construction sites in Australia. The findings revealed that, within the construction site context, contingent reward, idealised influence, and management-by-exception behaviours demonstrated by supervisors closely aligned with their definitions in Full-Range Leadership Theory (FRLT). These three types of leadership behaviour reflect observation of supervisors' positive actions, which included: praising workers for good safety performance; proactively anticipating and attending to safety issues; and consistently leading-by-example with safety, even at times of significant production pressure. Other theoretically described dimensions of leadership behaviour, i.e. individual consideration, inspirational motivation, and intellectual stimulation, were not directly reflected in observed supervisors' behaviour in the way they are conceptualised in FRLT. The existence of a good supervisor-worker relationship enabled workers to comfortably raise safety issues, think creatively about how to undertake work safely, and talk to their supervisor if they were experiencing personal problems. These are motivational, intellectual, and empathetic elements of leadership, which do not directly align with the way leadership behaviours are conceptualised in mainstream FRLT. The study suggests that, in the construction worksite context, leadership behaviours may take a form that differs from theoretical ideal types and that ethnographically attained insights into supervisors' interactions with workers can contribute to understanding transformational and transactional leadership in practical terms.

Building Information Modelling (BIM) can be defined as a process of generating and managing information of a building or infrastructure during its life cycle. Whilst the 3D visualisation or dimensional functions of BIM are not necessarily new, it is the usage and integration of this information related to project delivery, management and performance analysis that are challenging current construction industry practices. Industry has called for the development of more collaborative and integrated contractual arrangements to facilitate the use of BIM. Such recommendations appeal to the ideal use of BIM, but also provide a potential opportunity to seek improvement within the construction industry. This paper proposes a procurement approach to BIM to establish the applicable contractual context to address the potential legal risks and commercial considerations, relative to current practices in Australia. It also outlines why BIM, with other enabling technologies, will drive the evolution of contract delivery methodologies. [ABSTRACT FROM AUTHOR]

In recent years there has been increasing interest in the productivity and efficiency of the construction industry in New Zealand. In part this interest has manifested itself in the increased use of numerous statistical techniques to determine the productivity and efficiency of the industry. These efforts have, however, some degree of controversy. The purpose of this paper is,therefore, threefold. First it summarises the key structural findings that have been determined from past research into the construction industry in New Zealand.Secondly it makes some comparisons between the construction industry's productivity in New Zealand with that of the six states of Australia.Finally it also considers potential areas for potential future research.
