A critical review of vision-based occupational health and safety monitoring of construction site workers

Visual Analytics for Operation-Level Construction Monitoring and Documentation: State-of-the-Art Technologies, Research Challenges, and Future Directions

“…To do this, the present study leverages a content analysis approach for the systematic review of existing literature. It is a well-known approach for synthesizing the literature and deriving the objective findings, and its applicability has been extensively demonstrated in the areas of engineering and construction management (Yi and Chan, 2014;Mok et al, 2015;Liang et al, 2016;Li et al, 2018;Zhang et al, 2020b). Figure 3 illustrates the research methodology consisting consists of three main processes: journal article collection, initial article review, and in-depth article review.…”

“…The author also restricted the search to articles in mainstream journals, which were written in English as they are reputable and reliable sources (Zhong et al, 2019). Specifically, the well-known mainstream journals were chosen with reference to the findings of existing studies, which reviewed relevant research fields (Chen et al, 2018;Asadzadeh et al, 2020;Zhang et al, 2020b). They included Next, the publications that do not contain the aforementioned keywords in their titles or abstracts were filtered out, and less relevant and irrelevant papers were also screened out after a brief visual assessment of the content of articles.…”

“…Despite their encouraging findings, it remains a major challenge to exploit computer vision technologies in real-world construction sites owing to various theoretical and practical issues, implying that there are knowledge gaps in practice and theory. Hence, there have been a few studies to review computer vision research in construction and expand our understanding on state-of-the-art technologies (Seo et al, 2015a;Teizer, 2015;Yang et al, 2015;Ham et al, 2016;Xiao and Zhu, 2018;Fang et al, 2020b,c;Sherafat et al, 2020;Zhang et al, 2020b). However, because some of the review articles (Seo et al, 2015a;Teizer, 2015;Yang et al, 2015;Ham et al, 2016) were published before 2016, recent advances in deep learning and computer vision algorithms could not be covered.…”

“…In addition, recent reviews focused only on limited monitoring purposes and/or technologies of operationlevel monitoring, resulting in a lack of holistic understanding on state-of-the-art technologies. Specifically, Fang et al (2020b; and Zhang et al (2020b) investigated existing studies in the perspective of safety monitoring. The reviews of Xiao and Zhu (2018) and Sherafat et al (2020) were limited only to construction object tracking and action recognition technologies, respectively.…”

Influences of Migrant Construction Workers’ Environmental Risk Perception on Their Physical and Mental Health: Evidence from China

“…At their living sites, migrant construction workers face severe levels of domestic waste pollution around the accommodations. Restrained by living cost in urban areas, most migrant construction workers live in temporary housing made of iron plates and foam or in rental housing that had been abandoned by local residents, which are small, humble, and are almost only used for cooking and sleeping [ 25 , 42 ]. At the end of 2019, the average per capita living space of migrant workers in a Chinses city with a population of five million was only 16.5 m 2 [ 43 ].…”
