“…It can be denied that strong health condition is able to complete their work and reduce the risk of illness. Many construction task will handle manually, one of most studies [21] said that physical fatigue impacted awareness diminishes and worker safety as it lack of to process hazard information. Physical fatigue leads to a depletion of energy and decreased effectiveness when engaging in prolonged physical activities.…”

“…Hence, it is crucial for a company to proactively prevent fatigue, and doing so necessitates the capability to promptly identify it as it occurs. Physical fatigue affected to strong or weak physical health employee, physical fatigue has been recognized as one of the ten major risks faced by construction workers, with a high likelihood of leading to accidents [21]. Additionally, contractors in good health are more likely to assess project situations effectively.…”

Project risk assessment serves as an effective tool for overseeing cost, and time, and achieving technical performance in construction projects. The construction industry frequently contends with various uncertainties, which can lead to potential risks such as delays, cost overruns, and compromised quality in building and road construction ventures. Consequently, adept project risk management becomes crucial in the decision-making process of construction companies, ultimately determining project success or failure. This paper aims to assess the prioritize the specific factors influencing contractors' risk attitudes in these companies. The study employed simple random sampling under probability techniques. Data collection involved a thorough review of pertinent literature and the use of a questionnaire employing a five-point Likert scale ranging from (1) very low/very disagree to (5) very high/very agree. The sample size used for analysis was 47 companies, with a particular focus on the Sumatra construction companies. This study was analyzed using Statistical Package for Social Science (SPSS) version 23.0 for Microsoft Windows and a reliability test with Cronbach's alpha. The finding of this study is primary factors influencing contractors' risk attitudes are as follows: educational background, physical health, emotional intelligence, work experience, and professional competence, The results of this research can provide decision-makers with valuable insights into strategies for effectively managing contractors' risk attitudes, thus furnishing stakeholders with the requisite knowledge to enhance risk management performance within the Sumatera construction companies.

“…In construction-related research, there are various instances of the use of the SA theory to advance relative knowledge. Studies largely utilise the theory to improve safety (Ibrahim et al, 2023), planning (Martinez et al, 2023), and project management (Ghimire et al, 2016). Overall, Lappalainen et al (2021Lappalainen et al ( , p.2201 state that only a "small body of literature focuses on SA in the construction sector".…”

Purpose The construction industry has embraced building information modelling (BIM) as a practical methodology towards digitalisation. However, critics believe BIM has reached a plateau in addressing distinctive construction challenges. As a result, literature has seen an increase in the development and use of BIM-based plugins. Overall, the plugins have been critical in delivering custom-built solutions to longstanding construction challenges. The purpose of this study is to empirically investigate this trend and the potential barriers undermining the wider development of BIM plugins, by that contributing to a stimulating research topic and a growing knowledge gap. Design/methodology/approach Methodologically, this study used a quantitative approach to collect data through a carefully designed questionnaire. This study achieved a sample size of 39 experts who have been involved in developing, experimenting and publishing BIM-based plugins for specific construction activities. Findings The findings led to the identification of the key barriers to using BIM-based plugins and the identification of the key strategies to overcome them across the three situational awareness (SA) phases. Results also suggest that the development and use of plugins are destined to increase, and the research community can now rely on the insights of this paper as a departure point to address the technological plateau in BIM-related research. Originality/value To the best of the authors’ knowledge, this is the first study to empirically identify and assess the barriers undermining the wider development of BIM-based plugins. This study contributes to theory by building on SA, by challenging existing wisdom and fostering new knowledge around strategies to overcome the evaluated barriers.

“…Most workplace accidents are caused by poor SA in workers [27]. Ibrahim et al [28] used wearable sensors to track the physical fatigue of individuals in real time, discovering that physical fatigue would reduce the SA of workers and increase dangerous behaviors. Lee and Hasanzadeh [29] conducted a study using panoramic video and wearable sensors.…”

This study addresses the issue of poor construction labor productivity, exploring the process and methodology for increasing construction workers’ participation in labor productivity improvement, as well as a situational awareness (SA) development approach for construction workers based on lean construction (LC). A framework for enhancing labor productivity through SA has been developed. A case study approach is utilized to describe the LC improvement process, which includes enhancing construction workers’ SA for waste minimization and process optimization and engaging them in LC with improved value stream mapping (VSM). The labor productivity measurement approach, combined with VSM, is used to evaluate the labor productivity improvement with labor productivity improvement rate, resource efficiency, and flow efficiency. The results demonstrate that the labor productivity of the case project has increased by 24.07%, with 11.54% contributing resource efficiency and 88.46% contributing flow efficiency, indicating a greater increase in flow efficiency. This study fills a research gap in terms of the combination of construction workers’ SA enhancement and the involvement of LC practices to boost labor productivity. Furthermore, this study proposes an SA development approach based on LC at three levels: waste perception, VSM implementation, and labor productivity improvement assessment. This provides new perspectives for leveraging construction workers’ SA to increase labor productivity. The improved VSM approach and labor productivity measurements provide an operationalization of workers’ participation in continuous improvement. This research is of great practical relevance for augmenting the competencies of construction laborers and inspiring them to engage in labor productivity enhancement.
