Purpose: Offsite manufacturing (OSM) is a modern construction technique that offers several advantages over traditional construction, including using less material to produce a similar product, lowering costs, increasing quality and enhancing environmental sustainability of the final product in several ways. However, there is evidence of increased safety related incidents at an OSM facility due to the varying nature of its organisational safety climate. Therefore, this study aims to ascertain the relationships between organisational safety climate factors and safety performance in an OSM context, with a view to developing better safety outcomes. Design/methodology/approach: A Bayesian Network (BN) approach was adopted to uncover the probabilistic relationships among organisational safety climate factors. First, a literature review was conducted to develop a conceptual model, which was validated by industry experts. Second, a questionnaire survey with Australian OSM professionals was employed to quantify the BN model. Finally, a sensitivity analysis was performed to validate the BN model and identify critical factors. Findings: Owing to the influence of organisational safety climate dimensions, there is a 79% probability that Australian OSM facilities obtain "high" safety performance. Despite this result, improvements in management safety response, the balance between safety and production, supervisor safety expectations, credibility in training and accessibility to safety rules and procedures are critical to maintaining and improving this current outcome. Originality/value: This study develops a probabilistic model determining relationships between organisational safety climate factors and safety performance, particularly in an OSM context. The proposed model facilitates safety managers' comprehension of safety climate issues and provides decision-making support when implementing safety management strategies.

Construction projects are subject to uncertainties and hazards that pose significant risks to the health and safety of workers. The number of incidents caused by construction hazards is increasing, indicating an urgent need for more systematic hazard analysis methods and the development of effective preventive measures. Investigating incidents helps identify underlying patterns and trends, which is crucial for preventing recurrence and creating safer workplaces. While previous research has explored hazard investigation and the introduction of modern technologies for hazard prevention and mitigation, there have been limited efforts to analyze construction incident databases and identify the root causes of incidents through case studies. This study aims to address this research gap by conducting a case study that focuses on a database containing records of 10,415 construction incidents from 2014 to 2020 across New South Wales, Australia. The study adopted a two-step methodology, first conducting a descriptive incident analysis, followed by identifying hazard-specific interventions based on a literature review. Analyzing the frequency of occurrence revealed 10 high-risk hazards that caused the highest number of incidents across construction businesses. Falling objects had the highest frequency of occurrence, accounting for 19.59% of all incidents. Analyzing the frequency of incidents by business type also showed that residential construction is the most hazardous business in the construction industry, with 2,057 recorded incidents. This study contributed to the body of knowledge by revealing patterns, trends, and vulnerable areas to help identify the main reasons for the upward trend of incidents and address them with effective interventions.

Introduction: Advancements in the modern construction industry have contributed to the development of a range of technology-based interventions to improve the safety behavior of front-line construction workers. Notwithstanding the extensive research on safety behavior, there is still a paucity of research on assessing technology interventions of safety behavior to provide an overview of their strengths and limitations. The present study aims to bridge this gap in the literature and identify the main trends of research. Method: A systematic review and critical content analysis are adopted to capture an overview of the state of knowledge on safety behavior technologies. As a result of searching Scopus, Web of Science, and Google Scholar databases in the period from Jan 2010 to Feb 2023, a total of 359 potential studies went through the systematic screening process and finally, 48 representative studies were selected followed by an assessment of the feasibility and applicability of the safety behavior technologies. Results: It was found that safety behavior technology is characterized by seven technologies including virtual-reality simulation (T1), eye-tracking technology (T2), prediction modeling of safety behavior (T3), computer-based training (T4), drone/sensor-based hazard monitoring (T5), vision-based behavior monitoring (T6), and real-time positioning (T7). Conclusions: This research improves understanding of the status of safety behavior technologies and provides a critical review of their feasibility from the perspective of four assessment criteria including application, limitation, benefit, and feasibility. Practical applications: The categorizations of technologies add value to the body of knowledge in terms of generic requirements for their implementation and adaptation on construction sites.

Falling from height (FFH) is blamed for causing significant injuries and deaths on construction sites. Previous research has outlined a broad range of technological advances facilitating the management of the FFH safety risk. However, the extant literature lacks a comprehensive assessment to investigate the contribution of various FFH technologies, as well as their implementation feasibility on construction sites, which provides rationale for this study. The study aims to assess recent safety technologies which can be used to control the risk of FFH on construction sites, especially in urban building construction projects. A scoping review was conducted to identify such technologies and provide insight into their application in the construction industry. As a result of searching Scopus, Web of Science, and Google Scholar databases between 2010 and 2021, a total of 86 representative studies were selected and reviewed. Following this stage, an assessment of their feasibility was carried out based on a set of criteria from the literature. A total of 7 FFH technologies were identified, characterising the contribution of recent technologies to the prediction, prevention, and mitigation of FFH risks. These technologies include (1) Safety risk assessment and propagation, (2) real-time sensing and monitoring, (3) automated prevention through design, (4) ontology and knowledge modelling, (5) virtual reality for FFH training, (6) personal fall arrest systems, and (7) collective fall protection systems. This research contributes to an improved understanding of the status of FFH technologies. The feasibility assessment provides insight into suitable technologies for construction projects of various sizes and features.

Academic institutions play a prominent role in nurturing resilience skills in their graduates especially in fields, such as construction management (CM), which deal with a challenging work environment. Although resilience is a well-established topic in the literature, there is still a paucity of research that examines the importance of academic resilience interventions in the CM discipline. To address this research gap, this study aims to analyse the importance of academic resilience interventions (ARI) from the perception of CM students. First, the literature on ARIs in relevant contexts was reviewed followed by a quantitative survey to obtain the viewpoints of undergraduates undertaking CM programs in Australia. This paper is based on the survey data collected from 105 undergraduate students from five universities. Applying an exploratory factor analysis (EFA), three latent variables were found: (1) industry engagement; (2) raising awareness; and (3) readiness and empowerment to represent the identified ARIs. An importance analysis using the 2D quadrant method revealed that the ARI measures labelled "site visits," "role model," and "self-assessment" from the industry engagement aspect (factor1), "role-playing" from the raising awareness aspect (factor2), and "case study" from the readiness and empowerment aspect (factor3) are the most important ARIs from the perception of students. An independent-samples t-test revealed that there is no significant difference between the perception of male and female students on the importance of each ARI. The study provides an enhanced understanding of resilience interventions that can be leveraged for improving the CM curricula.

A Psychological Contract of Safety (PCS), based on mutual obligations between supervisors and workers, has been observed in an Australian construction context applied to safety. It has been described in recent research explaining the influential role of supervisors. In the past, there have been numerous studies establishing that the mainstream theory of the Psychological Contract (PC) affects behaviour when applied to various cultural backgrounds. Despite this, there is no established theory that explains how PCS may influence workers' behaviour in alternative cultural backgrounds. To test this theory, data were collected from construction projects in two divergent cultures, Australian and Chinese. A sample of 352 Australian and 374 Chinese construction workers completed a survey related to PCS and its influence on safety behaviour. Results from using Structural Equation Modelling show that there is a strong influence of the PCS on the safety behaviour of individual workers in both countries. Specifically, the Chinese workers placed higher PCS influence on both compliance and participation behaviour than the Australian workers. The research findings have been contextualized with managerial and cultural implications allowing practitioners to apply the mechanism to improve safety behaviours of workers in their respective cultural contexts. Conceptualising the extant PC theory as a framework from which to leverage PCS management initiatives brings a new approach to construction safety studies, revealing the influential role of supervisors in interpreting safety obligations in a cross-cultural construction setting.

Previous research enables managers to apply appropriate safety management factors for increased site safety. However, the heterogeneity of such factors in contemporary studies makes it difficult for practitioners to keep up to date with relevant alternatives. There is a paucity of systematic reviews that examine factors, map out their relationships, categorize research gaps, assess the practicality of research findings, and offer direction for future research. In this paper, a systematic review of 2574 articles published between 2010 and 2020 and a full-text examination of 75 quantitative surveys were conducted to catalogue, synthesize, and assess safety management factors in contemporary literature. Thematic analysis subsequently revealed 38 interrelated safety management factors to be classified under three individual, workgroup, and organizational groups. A critical content analysis of the representative studies was conducted to identify five future research trends as well as associated research gaps and directions on construction safety management in the form of an agenda suggesting a shift in research emphasis from physical safety issues to organizational and culture-related factors that have the potential to systematically enhance the overall safety performance. Furthermore, directions are provided to safety practitioners concerning the useful implementation of safety management factors.

Purpose: Safety climate and its impact on safety performance is well established; however, researchers in this field suggest that the absence of a common assessment framework is a reflection of the state of development of this concept. The purpose of this paper is to propose a five-factor model that can be used to diagnose and measure safety climate in construction safety research and practice. Design/methodology/approach: A systematic review was adopted, and following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, 574 articles were selected at the start of the study based on a developed review protocol for investigating safety climate factors. While examining the factor analysis of different studies, data reliability and data validity of the individual research findings were considered and frequency of factors uploaded was used to determine the significance as a quantitative measure to develop the ranking of safety climate factors. Findings: The review identified that, from the established measures of safety climate in construction, there is little uniformity on factor importance. However, management commitment safety system role of the supervisor; workers' involvement and group safety climate were found to be the most common across the studies reviewed. It is proposed these factors are used to inform a five-factor model for investigating safety climate in the construction industry. Originality/value: The findings of this study will motivate researchers and practitioners in safety to use the five-factor safety climate model presented in this paper and test it to develop a common factor structure for the construction industry. The fact that the model is comprised of five factors makes it easier to be used and implemented by small-to medium-sized construction companies, therefore enhancing its potential use.
