Three-dimensional concrete printing (3DCP) is a sustainable and green approach for rapid construction with the ability to create complex shapes to preserve the intended aesthetic appearance for an affordable cost. Even after a decade of attempts, there are many limitations and challenges to applying this technology for constructions without borders. The lack of guidelines for mix designs, quality control procedures during extrusion, printing and building phases, compatibility of material with extruder, standard testing, and guidelines to verify suitability of mixture with respect to the application and exposure conditions and limited machine capacity are several areas to be addressed for applications without borders. The development of 3DCP applications as a sustainable and green technology is another challenging task due to high Portland cement consumption in 3DCP. However, reducing the high usage of ordinary Portland cement (OPC) with pozzolanic waste materials replacement and environmentally friendly cement indicates the direction of moving 3DCP into a sustainable pathway. The authors reviewed more than 200 refereed articles published on materials and techniques in 3DCP. Inconsistency in disseminating knowledge in research articles has hindered the creation of a monolithically connected chain of research efforts and findings in accelerating the development and adoption of this technology. This paper summarizes the common approach to developing 3DCP mix designs and identifies the key areas for the future development of materials and techniques and challenges to be addressed for the global adoption of 3DCP. The current progress and challenges in the context of Australia's construction industry and future trends for the acceptance of 3DCP are also reviewed. [ABSTRACT FROM AUTHOR]

The Australian construction industry is facing a mental health crisis; poor mental health indicators are significantly higher than the all-industry average. Despite a growing body of research into the mental health of the industry's workforce, concerns have been raised about its alignment with regulatory developments in this area. This raises questions about the relevance of research to support mental health policy development in Australia and evidence-based research on mental health policy relating to the construction industry. However, there has been no research to explore the extent of this problem. This paper addresses this knowledge gap by reporting the results of a systematic review of peer-reviewed mental health research using the PRISMA scoping review methodology. The results reveal significant misalignment between existing research and Australian government regulation in this area. A particularly low level of research–policy alignment is found in the areas of: violence and traumatic events at work, financial concerns, poor organizational change management, workplace injustice, and social support. The paper concludes with recommendations for new avenues of mental health research to address these gaps, enabling closer alignment between mental health research and regulatory reform. It is concluded that this will facilitate more relevant research and improved evidence-based decision-making in this important field of research and policy development. [ABSTRACT FROM AUTHOR]

Despite substantial investments and efforts by governments, construction organisations, and researchers, the construction industry remains one of the most male-dominated industries in Australia, with women being underrepresented numerically and hierarchically. Efforts to attract and retain women in construction have been implemented inconsistently on an ad hoc basis. As part of a larger research project that focuses on retaining women in the Australian construction industry, this research conducts a systematic literature review (SLR) in accordance with the PRISMA guidelines. The objective is to explore the factors that influence women's careers and their experiences in the Australian construction industry that have been identified in the literature over the past three decades. Additionally, the findings are anticipated to inform future efforts to evaluate the effectiveness of current initiatives to retain women and develop a framework for enhancing women's experiences and retaining them in this profession. This SLR revealed that excessive and rigid work hours, gendered culture and informal rules, limited career development opportunities, and negative perceptions of women's abilities are the main factors and issues that cause women to leave the industry. Among these, rigid and long work hours seem to be the foremost factor to be prioritised. Understanding the roles of key variables in driving this cultural change is important to ensure that concrete progress is made. The paper draws three major aspects from the literature in which solutions and policies can be researched, designed and implemented. [ABSTRACT FROM AUTHOR]

Organizations play an essential role in fostering a diverse and inclusive work environment. Despite attempts to encourage gender diversity in the workplace, the construction industry in Australia remains one of the most male-dominated industries. Existing research tends to focus on identifying barriers to gender equality and women's career development, with limited exploration of organizations' current initiative implementation. To fill this research gap, this study aims to examine how organizations implement initiatives affecting gender equality and women's career development in the Australian construction industry. This study applied the women's empowerment framework and conducted a thematic analysis of diversity, inclusion, and equality policies, strategies, action plans, corporate reports, annual reports, and websites within the context of gender equality and women's career development in construction companies. Through a comprehensive analysis, the study identifies prevalent practices and initiatives related to gender equality initiatives in the construction industry, synthesizing them into six themes: flexible working arrangements, inclusive and anti-discriminatory culture, promoting career development, recruitment, and promotion, shared caring responsibility, and strategic commitments. The findings also revealed areas for improvement, giving recommendations on how to further empower women in the construction industry through enhanced gender diversity initiatives. This study sheds light on the current state of gender diversity and inclusion efforts within construction companies and provides practical recommendations for policymakers, industry stakeholders, and organizational leaders who seek to foster more inclusive and equitable work environments.

The use of Engineered Wood Systems (EWS) as structural alternatives or complements of traditional materials, such as steel and concrete, is of growing interest and acceptance in the architecture, engineering, and construction industries. Gathering evidence from the Australian context, this paper proposes a roadmap for the adoption of EWS as the primary structural materials of medium-rise buildings, with the scope of increasing levels of public awareness about the potential and current shortcomings of these building technologies. A nation-wide survey with stakeholders at the forefront of adoption in structural design, construction, and property development, indicates that the demand for timber in multi-storey projects has promising prospects of growth, but faces circumstantial industry-wide hurdles in the short to medium term. Awareness of benefits and inclination towards more use of timber among designers are positive factors that provide a promising base for further adoption. The translation of positive front-end design attitudes into adoption, however, requires holistic long-term investment efforts with industry-wide education. The pathway to innovation for timber in multi-storey projects needs to grow beyond mere promotional strategies of its benefits, seeking to expand technical knowledge through education and reaching out beyond a group of already committed and knowledgeable stakeholders at the forefront of adoption.

There has been a recent proliferation of social procurement policies in Australia that target the construction industry. This is mirrored in many other countries, and the nascent research in this area shows that these policies are being implemented by an emerging group of largely undefined professionals who are often forced to create their own roles in institutional vacuums with little organisational legitimacy and support. By mobilising theories of how organisational champions diffuse innovations in other fields of practice, this paper contributes new insights into the evolving nature of these newly emerging roles and the motivations which drive these professionals to overcome the institutional inertia they invariably face. The results of semi-structured interviews, with fifteen social procurement champions working in the Australian construction industry, indicate that social procurement champions come from a wide range of professional backgrounds and bring diverse social capital to their roles. Linked by a shared sense of social consciousness, these champions challenge traditional institutional norms, practices, supply chain relationships, and traditional narratives about the concepts of value in construction. We conclude that, until normative standards develop around social procurement in the construction industry, its successful implementation will depend on external institutional pressures and the practical demonstration of what is possible in practice within the performative constraints of traditional project objectives.

Gender equality at work in male-dominated industries is conditioned by intrinsic systemic issues which established policies have, to a significant extent, failed to address, as women's participation remains under-represented. This study argues for the reappraisal of the issue through a different lens and carries out a systematic and thematic review of the literature on women in construction in Australia through a women's empowerment framework. Despite its usual application in gender inequality at work in development studies, the concept of empowerment lacks attention in the context of developed countries, particularly regarding the construction industry. Empowerment has been proved a useful overarching framework to analyse personal, relational, and environmental factors affecting women's ability to be or do. In the examined studies, there is significant focus on external barriers to women in construction, such 'organisational practices' (environmental), 'support' and 'others' attitudes and behaviour' (relational). There is, however, limited attention to more active stances of power, such as one's attitude (personal), control and capacity, in shifting power dynamics. The paper draws seven major findings, covering personal, relational and environmental dimensions, supported and supplemented by some international studies, and suggests the way forward for empowering women in construction.

Embodied carbon is a buzzword in the construction industry. Australia is committed to achieving Net Zero 2050 targets, and minimizing embodied carbon (EC) is inevitable. Owing to the population growth, there will be a significant demand for residential construction. Therefore, the material consumption in residential construction should be evaluated and proper strategies should be in place to minimize EC. The aim of this research is to undertake a preliminary study of EC in the Australian residential sector, with an emphasis on new residential home construction. This research presents a preliminary study on EC in residential buildings in Australia. Three case study residential buildings were used in this study. All three case studies are single -story residential units, with a gross floor area between 200 and 240 m2. One Click LCA software was used to calculate the EC. The EC of three case study residential homes is between 193 and 233 kgCO2e/m2. Based on the findings of this study, 'other structures and materials' contribute to a large amount of EC in residential construction. Concrete and aluminum are considered significant contributors to EC. Therefore, it is vital to either introduce low-EC material to replace aluminum windows or introduce various design options to minimize the use of aluminum in windows. There are various sustainable concretes available with low EC. It is essential to explore these low-EC concretes in residential homes as well. This research identifies the importance of adopting strategies to reduce the carbon impact from other sources, including concrete. It is also essential to consider the EC through transportation related to construction and promote locally sourced building materials in residential construction. Therefore, the results of this research indicate the necessity of reducing raw material consumption in Australian residential construction by implementing approaches such as a circular economy in order to circulate building materials throughout the construction supply chain and reduce raw material extraction.

The aim of this study is to provide an overview of the current state of Industry 4.0 (IR 4.0) with regard to construction in Australia and to identify the key factors that are driving and hindering its adoption. A literature review and desktop review were conducted to extract mainstream topics, followed by a two-folded workshop designed with a multidisciplinary team of academics, as well as representatives of mainstream firms and peak bodies from the construction value chain. Our study has highlighted the importance of considering both technological and human-related factors in the adoption of IR 4.0 to address barriers that have been traditionally overlooked, and work towards a more successful and holistic implementation of this transformative paradigm. By considering the social aspects of construction, prioritizing data-driven approaches with a focus on privacy and ethics, and emphasizing integration, these facilitators contribute to the effective implementation and success of IR 4.0 in the construction industry. The findings of this study have significant implications for the construction industry in Australia. Addressing the barriers to digital construction adoption and embracing IR 4.0 technologies can help the industry to improve productivity, reduce costs, and enhance sustainability. Additionally, investing in education and training can help to build the necessary skills and capabilities needed to drive the industry forward in the digital age. [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.

This study explores the relationship between organisational culture and total quality management (TQM) implementation in Australia, with the purpose of identifying the particular culture that dominants the Australian construction industry, and distinguishing which cultures determine the successful implementation of TQM. Although the application of the competing values framework (CVF) for evaluating organisational culture (OC) in the construction industry has been studied by some scholars, research into OC and its impact on TQM procedures in connection to the CVF in project-based industries such as construction has received less attention. Thus, this research intends to determine the relationship between OC and TQM regarding the CVF in the Australian construction industry. The research methodology used the validated organisational culture assessment instrument (OCAI) CVF to frame OC, and TQM practices identified from the literature review. An online questionnaire was distributed through Qualtrics, whereby 42 valid responses representing various construction organisations in Australia were analysed through IBM SPSS Statistics 26 through endorsing k-means cluster analysis, and analysis of variance. The findings support that Australian construction organisations are dominated by the market and external focused cultures according to the CVF of organisational classification. Furthermore, the findings acknowledge that organisations that are dominated by hierarchical cultural characterises could provide an unfavourable environment for the successful implementation of TQM. Whilst an organisation that obtains a mix of cultures, specifically with the adhocracy and market cultures dominating could provide a favourable environment for the successful implementation of TQM.

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.
