Abstract
Purpose The demanding nature of construction industry poses serious health risks to construction workers.
In recent years, construction health management (CHM) has gained much attention to ensure a healthier and
safer workplace. However, there is still lack of a systematic review to bring together the disaggregated studies
and determine the development status of this research field. As essential for addressing health issues in
construction industry, a bibliometric and content-based review on of previous CHM studies would be presented
in this paper.
Design/methodology/approach In total, 753 journal articles published in Web of Science core collection
from 1990 to 2020 were examined using a systematic review. Bibliometric analysis concentrated on the analysis
of publication and citation pattern of CHM research while content analysis was employed to identify main
health hazards, levels of analysis and topical focuses.
Findings The results indicated that the USA was the leading country in this research domain. Five health
hazards together with 17 research topics at different levels of analysis were classified to allow researchers to
track the structure and temporal evolution of the research field. Finally, three emerging trends and a set of
research agenda were proposed to guide future research directions.
Originality/value It is the first to highlight the issues of occupational health management from the
perspective of construction workers. It contributes to the field of construction health management by clarifying
the knowledge structure, emerging trends and future research directions. It offers valuable guidance and
in-depth understanding to researchers, practitioners and policymakers to further promote construction
workershealth performance.

1. Introduction
The health risks such as cancers, respiratory diseases, musculoskeletal disorders (MSDs) and
noise-induced hearing loss (NIHL) are disproportionately high across the construction sectors
of many countries in worldwide (Dabirian et al., 2020;Dong et al., 2020;Jonsson et al., 2019).
For instance, previous epidemiological investigation revealed that, globally, about 77% of
construction workers suffer from the symptoms of MSDs (Dong et al., 2020). The poor health
records have caused sizable economic costs for workers, employers, insurers and society as
whole, attributing to the sickness absenteeism, healthcare costs, loss of productivity and
increased possibility of construction accidents (Peters et al., 2018;Chung et al., 2018).
Especially considering the depleting aging construction workforce, it is urgently required to
prevent deterioration of construction workershealth status, serving as one way to improve
workerswellbeing and projects performance (Chung et al., 2018;Eaves et al., 2016).
Recently, occupational health management has begun to receive widespread attention
from both academicians and practitioners in the construction industry (Chan et al., 2016).

Various health interventions have been implemented in construction industry, such as Total
Work HealthR in United States (Peters et al., 2018;Lee et al., 2017) and Pilot Medical
Examination Scheme for Construction Workersin Hong Kong (Yi and Chan, 2016), which
are critical for mitigating and reducing the health hazards. According to the International
Labour Organization (ILO) and World Health Organization (WHO), occupational health
management aims at prevention of disease and maintenance of workersphysical, mental and
social well-being (WHO, 1994). Construction health management (CHM) represents multiple
activities for preventing workers from adverse health effects including identifying health
hazards, performing health training and education, and promoting health performance,
motivation and behaviors (Lee et al., 2017)
In past decades, numerous studies on CHM have been published, forming a foundation for
promoting health performance in the construction industry. Thus, a comprehensive literature
review is indispensable for assisting major stakeholders in construction industry to gain an
in-depth understanding of the status of scientific developments in CHM research domain.
Although there have been some review studies on CHM research in the past (e.g. Chan et al.,
2020;Acharya et al., 2018;Roche et al., 2015), the overall analysis of CHM research is relatively
scant and previous reviews tended to have narrow research focus, sample and type of
analysis. For instance, ergonomic assessment reviews were primarily concerned with
available techniques and their limitations for assessing risk factors of musculoskeletal
disorders (MSDs) suffered by construction workers (Valero et al., 2016). Psychological health
studies concentrated on the state and risk factors of mental ill-health among workers (Chan
et al., 2020). Other health problems were also reviewed such as heat stress (Acharya et al.,
2018) and alcohol use (Roche et al., 2015). Although Jaafar et al. (2018) conducted a
comprehensive review on occupational health and safety management in construction
industry, they merely concentrated on the casual factors of limited health issues.
Furthermore, the majority of previous review studies are of a narrative type, which, in
contrast to systematic reviews, are difficult to gain a principled, transparent and reproducible
assessment of CHM research area (Abedinnia et al., 2017). To fill these gaps, a systematic
review based on bibliometric and content analyses was conducted in this research: (1)
bibliometric analysis (i.e., co-occurrence and frequency analysis) was carried out to identify
the most cited journals, the most productive countries and institutions, and hot topics in CHM
research; (2) content analysis (i.e., research subjects, levels of analysis and topics) was
eventually conducted to identify the knowledge structure of CHM and to guide potential
research directions in the future. Therefore, the current research goes even further than other
reviews as it provides a holistic and visualized analysis of various parameters, such as
country, publication sources and research topics. This research could assist researchers and
practitioners, especially new researchers in the field, to obtain an overview of CHM research
and potential research frontiers. The remainder of the paper is organized as follows. The
review process starts with the research methodology, followed by a detailed systematic
analysis. Finally, a qualitative discussion is provided to identify emerging trends in CHM,
along with the research gaps and potential future directions.
2. Methodology and data source
2.1 Methodology
This research used a systematic review that integrates the bibliometric and content analyses
to search and classify the intellectual knowledge of CHM research. The systematic review
could take advantages of two complementary approaches: bibiometric and content analyses.
The bibliometric analysis method is essential, especially for new researchers, to obtain a
broad picture of a research domain by exploring trends related to keywords, journals,
countries and institutes, while the content analysis could obtain more in-depth information
ECAM
about the subjects, research levels and topical focuses of related studies. Currently, the
systematic review has become a common approach in assessing the scientific status of
various disciplines, like supply chain management (Kazemi et al., 2019), construction safety
management (Liang et al., 2020), building information modelling (BIM) (Oraee et al., 2017).
Similar to previous studies, the review process follows a four-step methodology suggested by
Mayring (2010), namely (1) material collection, (2) bibliometric analysis, (3) content analysis
and (4) material discussion. The research process was presented in Figure 1. The database
and retrieval strategy were determined first to prepare a reliable and representative data
source. Irrelevant documents were then excluded through a series of screening criteria.
Bibliometric analyses were carried out to assess the publication and citation characteristics of
CHM research. Next, content analysis was provided to summarize main research themes.
Finally, potential research trends and gaps were discussed, and potential research directions
were recommended to guide future research.
(1) Bibliometric analysis
Bibliometric analysis, firstly introduced by Pritchard (1969), is an effective method to
quantitatively assess scientific activities in a research domain using statistical and
mathematical techniques. Bibliometric analysis combines two main procedures:
performance analysis and science mapping. The former assesses the performance and

impact of scientific productions based on various indicators like frequency, citation and
network centrality, while the latter visualizes the general knowledge structure of one research
field (Liang et al., 2020). In this research, both bibliometric procedures were conducted to gain
insights into publication and citation patterns, and main research topics in CHM field.
VOSViewer version 1.6.3, Gephi version 0.9.2, and CiteSpace version 5.7.R2, three
powerful bibliometric analysis software tools, were applied to perform the co-citation and
co-occurrence analyses to visualize and explore the emerging trends in the CHM research
domain (Van Eck and Waltman, 2009;Bastian et al., 2009). VOSViewer and Gephi could create
distance-based maps of networks where distances among nodes indicate the level of
similarity among them (Van Eck and Waltman, 2009). The burst detection was performed by
CiteSpace to examine the temporal evolution of hot topics over the whole investigative period.
Some basic statistical analyses of citations and publications in terms of counties, institutes
and journals were supported by HistCite version 2.0. Multiple indicators were used to assess
the development of the knowledge domain. The h-index, introduced by Hirsch (2005), means
that a subject, which can be one author, country, institute or journal, has published at least h
papers that have more than hcitations. In this research, the h-index was used to represent the
impact of a subjects cumulative publications on CHM research. Weighted degree is a
frequently used indicator reflecting the centrality of each node in the network, which is equal
to the sum of edge weights associated with a given node (Feng et al., 2016). The higher the
weighed degree, the more influential one node is in the CHM field.
(2) Content analysis
Although bibliometric analysis could analyze a large set of data and provide the general
publication trend of a specific domain, it does not give detailed information regarding the
content of studies of interest (Esen et al., 2020). Therefore, the content analysis was further
performed to acquire an in-depth understanding of the CHM research and explore the
temporal evolutions of research topics (Abedinnia et al., 2017). The content analysis
concentrated on the publication distribution of health hazards investigated, research levels
and topical focuses of each CHM article. Both conventional and directed content analysis
suggested by Hsieh and Shannon (2005) were implemented, where the coding categories of
health hazards and research levels were mainly from previous studies, while topical focuses
were codded directly from the text data. Each author would perform all the selection and
coding procedures independently to increase the validity and reliability of these assessment
(Aliyev et al., 2019).
2.2 Data source
Occupational health is a broad concept involving workersphysical, psychological and
behavioral aspects (Jones et al., 2019). Specifically, physical health is concerned with the
biological and physiological issues such as low back pain, cardiovascular and respiratory
diseases; mental health involves some poor psychological symptoms such as anxiety, tension,
depression and burnout; behavioral health focuses on health-risk behaviors and lifestyles
such as smoking, alcohol-drinking and substance abuse (Leung et al., 2012,2016b;Shirom,
2003). More importantly, this review concentrated on the health issues of frontline
construction workers rather than the project managers because the former seems to be much
more vulnerable to health harms than the latter (Nwaogu et al., 2020). Based on the systematic
analysis of the potential terms, a three-level keyword structure is adopted to cover diverse
and large-scale search terms for comprehensively and reliably obtaining CHM articles
(shown as Table 1). The context keywords define the search context which is limited to
construction industry; the subject keywords limit the search subject to construction workers;
topical keywords further narrow the search scope. In addition, the research timespan was set
19902020 and the article language was limited to English.
ECAM
This research selected the Thomson Reuterss Web of Science (WoS) core collection database
because it offers a useful source for standardized and high-quality academic publications.
Moreover, the data format of the WoS core collection database could meet the requirement of
various bibliometric techniques. Especially, the CiteSpace only supports the WoS database.
This research conducted the online retrieval and obtained 2,294 bibliographic data records. In
terms of the initial screening, 62 proceedings papers, 20 early access and 1 retracted
publication were removed from the dataset. Next, a total of 2,211 candidate articles were
subjected to the following manual screening process. The information provided in titles,
abstracts and even the full text (if necessary) of these articles were reviewed to remove the
articles which were not really related to the topic of construction health management. After a
careful screening process, a total of 753 CHM-related articles were identified for the following
literature review.
The distribution of annual publications from 1990 to 2020 is shown in Figure 2. Interests in
construction health management increased slowly before 2002, then had an incredible

development where about 83% of the literature was published between 2003 and 2020. The
increased number of publications indicated that CHM research had attracted extensive
attentions and become a critical domain in construction management. The total 753 articles,
had received a total of 12,658 citations, an average of 16.81 citation per paper. Average
citations of papers reached the peak in 1992 with a record of 70.29 and then dropped arguably
due to the time required for the accumulated effects of new publications (shown as Figure 2).
3. Bibliometric analysis
3.1 Countries/institutions cooperation analysis
A total of 58 countries/territories were found to contribute papers related to CHM, while
67.24% of these countries/territories contributed more than one paper. The span of
geographical area, to some extent, indicates that construction workershealth issues are
global concerns. Gephi software was used to visualize the cooperation relationship among
these countries/territories. The threshold was set at 5, which means that only countries/
territories that published more than 5 articles are included in the resultant networks. The
cooperation network was shown in Figure 3. Weighted degree is a comprehensive measure
for evaluating the level of influence of nodes in the control of information flow across the
whole network (Prell, 2012). The weighted degree values were used to resize and recolor the
nodes in the network in Figure 3, where darker and larger nodes represent higher weighted
degree values. In the cooperation network, thicker edges denotes closer cooperative
relationship between two countries or research institutions.
Table 2 lists the top 10 most productive countries, together with their weighted degree,
citation and h-index. Computing the Pearson product moment correlation coefficient (r) shows
that the counts of publication have strong positive correlations with other indicators. Thus,
productive countries tend to have higher performance in citation, weighted value and h-index.
For instance, the USA leads this research field with 270 articles, and also has the highest

scores in terms of citation (4,617), weighted degree (74.0) and h-index (34), indicating the
domination position of the USA in CHM research area. Indicated by darker and thicker edges
between them in Figure 3, the USA and Sweden are also two influential countries in CHM
which have frequent international cooperation. In practice, China is the only one developing
country among the leading contributors. With repaid economic development and huge
infrastructure construction in past decades, Chinese government and society have attached
great importance to the occupational health of massive labors onsite to obtain a sustainable
workforce (Chen et al., 2018).
A total of 791 institutions contributed to the CHM research, and 80 institutions of them
published more than 5 articles. The cooperation network among top 21 institutions with
citation was shown as Figure 4.Table 3 gives the top 10 most productive institutes, together

with the scores of citation, weighted degree, and h-index. The ranking of the institutions
differs significantly according different indicators, where the correlation between publication
and other indicators are not significant. For the publication counts, Hong Kong Polytechnic
University ranks the first with publication of 50. However, it has relatively low values of
citation (371) and h-index (13). This is primarily due to that Hong Kong Polytechnic
University is a recently emergent contributor in CHM research, and published most of CHM
articles around 2016, which makes it difficult to have strong accumulative citations. Based on
the citation, most influential institutions are Karolinska Institute (1225) and Harvard
University (1133), while based on the weighted degree, most influential institution is
University of Amsterdam (20), which is reflected by the dark color in Figure 4. Regarding the
cooperation relationships, two research groups could be identified based on the darkness of
connections between nodes: one group primarily consists of University of Amsterdam
(Netherlands) and Arbouw (Netherlands); anther one involves Umea University (Sweden),
Karolinska Institute (Sweden) and International Agency for Research on Cancer (France).
Above statistical analysis could provide valuable information for researchers who have
interests in the field of CHM to choose the potential collaborators.
3.2 Journal co-citation analysis
The selected 753 articles were published in 225 different journals, while most of these journals
(63.11%) published only one paper. The journal co-citation directed network was visualized
by the Gephi (shown as Figure 5). Only top 30 journals with the most citations are included in
the resultant network. Table 4 lists top 10 productive journals together with values of citation,
weighted degree, h-index and Impact Factor (IF). Based on the Pearson correlation analysis, it
shown that publication counts have strong positive correlations with citation, and h-index,
suggesting that each of these indicators could be effective to assess the importance and
contribution of these journals (Wuni et al., 2019). American Journal of Industrial Medicine is
the leading journal in CHM research in terms of the scores of publication (68), citation (1222),
weighted degree (155,523.0) and h-index (21). As indicated in Figure 5, this journal has amount
of information outflow (through citation relationships) to Occupational and Environmental
Medicine, Scandinavian Journal of Work Environment & Health and Journal of Occupational
and Environmental Medicine. The Pearson correlation coefficient (r) between IF and
publication (r50.002, p50.995) is not significant. This could be explained that IF reflects the

comprehensive influence of one journal in multiple domains, which could not be always
consistent with its influence in the domain of CHM. For instance, Automation in Construction
ranks first in terms of IF scores (4.313) which is influential in general application of
automation and robotics in construction industry but it has relatively low scores in other
indicators like publication, citation and weighted degree in CHM research. In practice,
Automation in Construction is recently emergent in CHM research area with average
publication year of 2017, indicating that it had increasing interests in the occupational health
issues and has published more CHM-related articles recently. Other emergent journals
include Journal of Cleaner Production (2017) and Journal of Computing in Civil Engineering
(2016). Knowledge of these above measures of impact could guide researchers on the choice of
suitable journals to submit research articles. Engineering, Construction and Architectural
Management has paid increasing attention on CHM-related issues recently, primarily about
the intervention of infectious virus and the effectiveness of health programs (Loudoun and
Townsend, 2017;Edwards and Bowen, 2019).
3.3 Keyword co-occurrence analysis
Topics were detected using keyword co-occurrence analysis provided by VOSViewer, which
was shown as Figure 6.Table 5 lists top 20 most frequently studied keywords together with
their scores of weighted degree. A correlation analysis shows that there is a strong positive
correlation between occurrence and weighted degree (r50.929, p50.000). Ergonomics
(occurrences 538, weighted degree 567.0), musculoskeletal disorders (38, 67.0) and posture
(27, 37.0) are the most influential keywords indicating the dominant position of topics related
to workersmusculoskeletal disorders in CHM research. From the topics identified from
keyword analysis, it could find that most CHM research were conducted specifically for

Top 20 influential
keywords under three
clusters
Structure and
emerging
trends of CHM
Cluster 1#, marked by green color, is primarily about the physical health. This cluster
involves topics related to ergonomic and environmental hazards that may cause harms to
workers, which is indicated by keywords musculoskeletal disorders,”“low back painand
noise.Musculoskeletal disorders were one of the most serious physical health problems
among construction workers. For instance, low back is the most vulnerable body part for
MSDs, and more than 50% of the construction workers suffer from symptoms of low back
MSDs annually around the world (Umer et al., 2018). Other progress has been made in
understanding the causal factors of musculoskeletal injuries involving three aspects:
physical exposure (e.g., awkward postures, repetitive motions, forceful exertions),
psychological stressors (e.g., work-family conflict, time pressure and safety worries) and
individual factors (e.g., gender, age, poor physical/mental health conditions) (Ekpenyong and
Inyang, 2014;Wang et al., 2015;Inyang et al., 2012;Zhang et al., 2021;Zhang and Lin, 2020). In
addition, within this cluster, wearable devices,”“machine learningand electromyography
represent potential technologies to monitor health status of construction workers in a much
automatic and accurate manner.
Cluster 2#, marked by red color, which covers studies related to epidemiology
investigation. Multiple epidemiology studies have focused on assessing the characteristics
and health impacts of occupational exposure and unhealthy behaviors among construction
workers (Lewkowski et al., 2018;Li et al., 2016). As shown in Figure 6,asbestos,”“diesel
exhaust,”“lead exposureand respirable dustwere frequently investigated chemical
hazards. Other hot keywords represents behavioral hazards like smoking, alcohol and
substance abuse, poor diet-related behaviors and physical inactivity, which have been found
prevalent among construction workers causing serious health problems (e.g. cardiovascular
and respiratory diseases, lung cancers, diabetes and obesity) (Flannery et al., 2019;Asfar et al.,
2018;Chin et al., 2012;Okechukwu et al., 2012). For instance, Loudoun and Markwell (2017)
found that soft drinks (e.g., caffeine) were consumed widely and regularly on site which could
influence the hydration and cause risk of heat stress.
Cluster 3#, marked by blue color, is primarily about psychological heath involving
keywords like mental health,”“suicideand job satisfaction.Mental health, such as
sadness, depression, and anxiety, represents another adverse health conditions, which has
been investigated in terms of their prevalence and adverse effects (Lim et al., 2017a). Previous
studies have found that about 20% of construction workers suffered from substantial mental
distress (Boschman et al., 2014;Jacobsen et al., 2013). Psychological health could influence
work motivation, job satisfaction and even cause suicide (Langdon and Sawang, 2018;Lee
et al., 2017;Leung et al., 2010). Recently, elevated suicide rates among construction workers
deriving from psychological problems have caught the attention of CHM researchers (Milner
et al., 2019).
4. Content analysis
4.1 Health hazards
The health causes were examined in detail through reviewing the content of each CHM
article. A total of 521 articles provided the specific health hazards which were summarized
in Figure 7. Based on the above keyword cluster analysis and previous health research,
various health hazards were identified among construction workers onsite, including
physical, chemical, behavioral, psychological and biological aspects (Sivakumar et al., 2012;
Epp and Waldner, 2012). Consistent with Aarhus et al. (2018), physical hazards have
received the most attention among previous CHM-related studies, accounting for 51.4% of
all papers. Among these studies on physical hazards, most concentrated on ergonomic risks
with a percentage of 71.6%, followed by heat strain (12.2%), noise (9.6%), and solar
ultraviolet-radiation (3.3%). Studies on chemical hazards occupy the second place
ECAM
accounting for 19.5%. Chemical hazards represent these harmful substances generated
during construction activities including solid particles, toxic gases and organic solvents. It
is found that lead (with a percentage of 14.8%), silica (14.8%), dust (13.0%) and asphalt
(11.3%) were four most frequently investigated chemical hazards. Behavioral hazards
ranking third (15.4%), refer to health-risk behaviors such as smoking, alcohol and
substance abuse, poor diet-related behaviors, etc., and smoking draws the most interest
with a percentage of 38.5%. Psychological hazards, ranking forth in CHM research (12.0%),
are those factors that can cause stress, strain, and other mental issues. Job stress (e.g., time
pressure, injustice and conflicts) and work environment (e.g. high altitude or elevation) are
two most investigated factors accounting for 32.4% and 12.7%, respectively. Finally,
biological hazards, representing infectious agents that can cause harm to human body,
have received the least attentions with percentage of only 1.7%, where scholars have paid
attention to HIV, Tetanus and especially the new coronavirus (COVID-19) among
construction workers.
Figure 8 gives the temporal evolution of health hazards investigated in CHM research. It
could be found that physical hazard is a long-lasting topic and shows an upward trend over
the whole investigative period. Psychological hazards began after 2000, and has a significant
increase recently. It could be primarily explained that occupational stress, mental health and
wellbeing have received more attention considering the intensification of job stress and aging
workforce as well as the increasing risks of suicide witnessed in the construction industry
(Milner et al., 2018;Langdon and Sawang, 2018). By contrast, there are few studies that
investigated the biological hazards in the construction industry over the whole investigative
period. Considering increased occurrence of infectious disease has been reported among
construction workforce, especially for the COVID-19 pandemic (Amoah and Simpeh, 2020),
more biological health research should be strengthened in the future.

4.2 Levels of analysis
Based on the general categories of research levels in construction industry (Zhou et al., 2015;
Goel et al., 2019), four research levels were defined in this research, including population,
industry, organization and task levels. Population level studies primarily concentrated on the
demographic characteristics of occupational illnesses or hazards among construction
workers. Industry level represented the studies on various agentshealth practices in the
construction industry, like government, insurance companies and health service centers. By
contrast, organization level studies investigated the implementation of health interventions
within construction companies or projects. Studies at the task level further limited the scope
into the health risks of some specific construction tasks. The distribution of publications
according to the five levels was shown in Figure 9. Population level accounted for almost half
of all the studies (42.1%), followed by organization level (33.8%) and task level (20.7%). It was
noted that only 3.3% of the papers were focused on industry level. The studies at population
level primarily investigated the prevalence and severity of health problems among specific

groups of construction workers, such as migrant construction workers (Susseret et al., 2019),
older construction workers (Dement et al., 2018), and elementary workers (Hamid et al., 2019).
The studies at organization level included investigation into projects of different types, such
as residential project (Nussbaum et al., 2009), prefabricated project (Kim et al., 2011), railway
project (Yang et al., 2015), electrical transmission and distribution project (Techera et al.,
2019), as well as some small construction companies (Dale et al., 2016). The tasks investigated
in task level studies were demolition (Bello et al., 2019), rebar tying (Umer et al., 2017b),
asphalt pavement (Hammond et al., 2016) and wall plastering (Rahman et al., 2012).
4.3 Topical focuses
The topics in CHM research at different levels were further investigated to summarize the
distribution and temporal trends of CHM research. 753 studies at population, industry,
organization and task levels were considered to summarize the multilevel health
interventions, which was shown in Table 6. Among two topics at the population level,
health data statistics (T1)is the largest, accounting for 22.3% of the total papers, which
conducted statistics of health records to identify prevalence and trends of health hazards or
diseases among construction workers. For instance, Dong et al. (2019) explored heat-deaths
among the American construction workers from 1992 to 2016 and found that heat risk has
increased with climate change over time. For the industry level, health practice (T3)is the
most frequently studied topic (1.7%), which aims at exploring the status of health practices in
construction industry. For instance, Jones et al. (2019) investigated current approaches to
managing occupational health in the construction industry and their limitations such as
lower priority than safety, lack of ownership and poor health service provision. For the
organization level, studies on health program (T8)are the most cited, accounting for 12.2%
of the total, which focused on assessing the effectiveness of health programs, such as
participatory ergonomics (Visser et al., 2019), nutrition training (Chung et al., 2019) and
smoking cessation services (Asfar et al., 2019).
Two health intervention perspectives were identified, namely behavior-driven health
intervention and technology-driven health intervention. Behavior-driven health intervention
focuses on preventing ill-health behaviors, which includes three main topics, namely health
behavior (T12)(1.7%), health knowledge (T14)(0.3%) and health leadership (T15)

(0.1%). In contrast, technology-driven health intervention focuses on the adoption of
innovative technologies to promote occupational health. Innovative technologies that have
potentials for promotion in construction, including BIM, 4D computer-aided design (CAD),
virtual reality (VR), online databases, location, sensing, imaging and warning technologies
(Zhou et al., 2012,2015).
Topics on technology-driven intervention include health monitoring (T10)(6.0%),
health planning (T11)(1.7%) and prevention through design (T13)(0.7%). Health
monitoring (T10)focused on the construction process, involving vision-based monitoring
and sensing-based monitoring. Vision-based technologies consist of the depth camera (Zhu
and Cao, 2014) and RGB camera (Yu et al., 2019); while wearable sensors include motion
sensors such as inertial measurement unit (IMU) (Chen et al., 2017;Yan et al., 2017), and
physiological sensors such as electromyography and heart rate (EMG) (Umer et al., 2017b;
Hwang et al., 2016). Health planning (T11)and prevention through design (T13)
concentrated on promoting occupational health in a proactive manner. For instance,
construction site layout could be optimized before construction to reduce noise pollution
(Ning et al., 2019). Automated biomechanical simulation approach could be applied for job
analysis to eliminate ergonomic hazards during the workplace design (Golabchi et al., 2015).

terms of their occurrence ratios in four time periods (19901998, 19992006, 20072013,
20142020). This shows that the percentages of some established health interventions had
significant decreases over the whole investigative periods. As an illustration, research topic
health investigation (T2)at population level dropped from 40.3% of the total in the first time
period to 11.0% in the last time period. In contrast, some topics expanded rapidly, especially
at the organization level. The topic health monitoring (T10)witnessed a significant growth
in past 6 years, increasing from 1.4% to 11.9%, and health performance (T9)(from 9.3% to
13.8%) and health planning (T11)(from 1.4% to 2.3%) also had a steady increase.
To further verify the temporal evolution trend identified through above content analysis,
the burst detection provided by CiteSpace software was carried out to examine strong burst
terms extracted from the title, abstract and keywords of 753 articles. Totally, 55 strong burst
terms were identified, the detailed information of which has been provided in Supplementary
Material. The terms with strong burst strength represent that associated studies have
notably increased over a short time, and often predict the emerging trends. CHM research
initially focused on the epidemiological investigation of illnesses or injuries suffered by
construction workers, which was indicated by dominant ratio of PHM (66.1%) during the first
time period (from 1990 to 1998), which was consistent with strong burst terms epidemiology
(with a burst strength of 5.32, from 1992 to 2007)and neck shoulder pain (4.16, 19922007).
Health risks at the task level has received more attentions during the second time period
(19992006), which could be indicated by the steady increase of topic risk assessment (T16)
and health measures (T17).Representative burst keywords in this period included risk
(4.61, 20022004)and exposure assessment (4.44, 20012004).Based on the theories of
organizational behaviors and engineering techniques, CHM research had further
development during the third period (20072013). During this period, some health
interventions were frequently explored like the topic health insurance (T5),”“adoption of
health innovation (T6),”“prevention through design (T13)and health behavior (T14).In
the last period, innovation techniques have attracted more interests to improve the accuracy
and efficiency of onsite health management. The terms with high burst strength included
wearable devices (5.77, 20172018)and machine learning (3.75, 20182020),which was
consistent with the fast increase of topics health monitoring (T10)and health planning
(T11).At the same time, psychological health has become a hot area, indicated by the strong
burst terms of mental health (3.92, 20182020)and mental fatigue (3.57, 20172020),
which was aligned to the increasing trends of psychological hazards as mentioned earlier.
5. Discussion
5.1 Emerging trends of CHM research
5.1.1 Increasing diversity of research topics. Research topics in the CHM field have become
diversified during the whole investigative period, which was shown in Figure 10. With the
continuous improvement of health awareness among construction practitioners, CHM
research has shifted from merely assessing the characteristics of health hazards or diseases
at task level or population level to proactively promoting occupational health at project level
or industry level (shown as Figure 10). CHM research has applied the general management
theories to address occupational health problems. For instance, the social network and health
leadership have been explored to achieve a sustainable improvement of construction
workershealth status (Yuan et al., 2018;Zuo et al., 2017). Construction workersknowledge
and attitude towards vaccine were found to be critical to increase the coverage of immunity
towards infectious diseases such as tetanus (Ricco et al., 2016). Furthermore, some topics
emerged with the development of new construction practices. With the application of new
products in construction like nanomaterials and green products, the possibility of new
chemical exposure has attracted attention to eliminate associated negative health effect
Structure and
emerging
trends of CHM
(D
ıaz-Soler et al., 2019;Al-Bayati Ahmed and Al-Zubaidi Hazim, 2018). In addition, in
response to greenhouse effectand changing global temperature, heat stress has become a
critical health risk in CHM research (Rowlinson et al., 2014).
5.1.2 Increasing application of innovation technologies. High burst terms like wearable
device (5.77, 20172018)and machine learning (3.75, 20182020)indicated that innovation
technologies represented one emerging trend in CHM research. Compared with other
industries, construction industry exists several unique characteristics, including the
transitory and diverse nature of construction activities (Zhang and Fang, 2013), the
complex and unstructured construction sites (Zhou et al., 2015), and the difficulties of
management because work crews are spatially dispersed and have responsibility for various
tasks away from the contractors office (Liang et al., 2018a). In addition, due to construction
workersunique characteristics (e.g. age, experience, physiological characteristic and gender),
they might have different psychological and physiological responses towards a certain task
demand (Jebelli et al., 2019). Therefore, construction health management practices need the
application of innovation technologies to capture and deal with these novel, various and
personalized health hazards and risks (Antwi-Afari et al., 2019). There are increasing
application of innovative technologies in health monitoring (T10) and health planning (T11)
in the last two time periods, as shown in Figure 10. This reflects that the potential of
innovation technologies to enhance CHM has been recognized, and more application of novel
technologies would be a future trend in CHM research.
5.1.3 Increasing concern of workerspsychological health. Given the new forms of
employment and intensification of work, the construction industry become more stressful in
recent years (Boschman et al., 2013). As indicated by Figure 8, CHM studies have shown more
interests on the psychological hazards of health because of the increasing mental-ill health
problems among front-line workers found recently including stress disorders, anxiety,
depression and suicidality (Nwaogu et al., 2020;Jones et al., 2019). High burst terms mental
fatigue (3.57, 20172020)and mental health (3.92, 20182020)also indicated that
psychological health represented one hot topic recently. CHM researchers have investigated
the risk factors and coping behaviors that might influence the metal ill-health among
construction workers (Hsu et al., 2016;Liang et al., 2018b;Langdon and Sawang, 2018).These
risk factors can be grouped into three categories: personal characteristics (such as age (King
et al., 2019) and masculinity (Kotera et al., 2019)), organizational factors (such as job demand,
job control and social support (Chan et al., 2020)) and environmental conditions (such as
extreme weather (Liang et al., 2018b) and financial crisis (Navarro-Abal et al., 2018)). As for
the consequence of mental health, the spillover effect models of mental health have been
developed, which link mental ill-health to other project outcomes such as safety performance
(Leung et al., 2010,2012;Wu et al., 2018;Wang et al., 2018) and productivity (Maqsoom et al.,
2019). As one way to obtain a sustainable workforce, more empirically supported mental
health studies will be carried out in the future as guides for managers to select most effective
interventions for mental-ill health.
5.2 Research gaps and agenda
5.2.1 Lack of clear definition of health management system. Current CHM research suffers
from serious fragmentation which often concentrated on the management of one specific
health hazard in terms of physical, chemical, psychological, biological and behavioral aspects
(shown as Figure 7). However, there is still lack of systematic studies to identify main
components and their interrelationships of health management system, which could supply
suitable and general framework to guide how to improve the health management
performance (Li et al., 2017). Despite it is mentioned together with occupational safety in
international standards OHSAS 18001 and the latest ISO 45001, occupational health seems
ECAM
often not to be equally treated like safety in whether academic studies or practices (Dahler-
Larsen et al., 2020). Previous studies on the occupational health and safety tend to focus
exclusively on safety hazards, and if any, only include some acute illnesses (Jones et al., 2019;
Jaafar et al., 2018). In industry practice, there is also no effective occupational health system
primarily due to the invisibility and latency of health effects, and managersand workers
lack of knowledge on how to promote occupational health (Jones et al., 2019). Therefore, much
clearer definition and key dimensions of health management system (e.g. management
support and worker engagement as well as other organizational aspects like risk
management) and their relative effectiveness for various occupational health issues should
be explored empirically in the future (Li et al., 2017).
5.2.2 Lack of wide adoption of innovation technologies. The adoption and implementation
of innovation technologies, such as vision-based technologies and wearable sensing
technologies, presents great potential to improve construction health performance (Ahn et al.,
2019;Zhu et al., 2017). However, despite slight increase in technology adoption has been
witnessed, a notable resistance regarding the continuous use remains an issue in construction
industry (Zhou et al., 2015;Nnaji and Karakhan, 2020). On the one hand, the technologies
developed in laboratory environment are still not adequate to adapt to the complexity onsite
(Antwi-Afari et al., 2019). For instance, vision-based technologies (e.g., RGB camera) are
limited by the fact that a direct line of sight is required to monitor the movements (Antwi-
Afari et al., 2018); while wearable sensors(e.g., IMU and EMG) are difficult to detect the
ground reaction force data of the whole body, and may make worker feel uncomfortable and
inconvenient while performing a give task (Chen et al., 2017a;Umer et al., 2017a). On the other
hand, the extra expense for purchase and required training, the lack of technology support
and concern of the usefulness of innovation technologies also hinder the wide adoption of
innovation technologies (Nnaji and Karakhan, 2020). Therefore, barriers of technology use in
the construction industry and corresponding strategies to overcome barriers need to be
further explored in the future. Furthermore, the current technology-driven CHM research
tends to focus on one specific hazard such as awkward posture, mental stress and noise
(Valero et al., 2017;Jebelli et al., 2018;Ning et al., 2019). In order to improve the efficiency and
cover most of health hazards, the integrative platform that supports the interoperation of
different information technologies should be studied in the future (Jin et al., 2019).
5.2.3 Lack of multilevel behavior-driven health research. Despite the importance of
technological improvement and working environment, health issues could not be absolutely
eliminated without workershealth behaviors (e.g. their compliance with health rules and
actively participation in health programs). However, only 1.7% CHM studies paid attention to
workershealth-related behaviors (shown as Table 6). There is still lack of behavior-driven
health research to explore workershealth behaviors from multi-levels, including individual,
group and organization. For the individual level, current studies have not given a clear
definition on health behaviors, and future studies could develop the scale of health behaviors
from various dimensions like health compliance and health participation. The individual
factors (e.g. personality traits, health knowledge, motivation and attitude) that directly
determine workershealth behaviors should be empirically explored. For the group level, it is
well-documented that social norms could exert potential effects on individual workers
behavioral decisions (Choi et al., 2017a,b). Future studies should compare the social contagion
effects of coworkersand supervisorshealth behaviors (e.g., use of health protection and
healthy lifestyles) on individuals (Liang and Zhang, 2019;Liang et al., 2018a). For the
organizational level, the health leadership could be explored to guide the managershealth
awareness and responsibilities (Zuo et al., 2017;Umeokafor, 2018). The core dimensions of
health-specific organizational culture, namely the health culture, could be further determined
to promote the continuous improvement of health performance onsite (Parker et al., 2017).
Structure and
emerging
trends of CHM
5.2.4 Lack of effective biological health interventions. Construction workers tend to be
vulnerable to the biological hazards, especially the viral transmission, considering the labor-
intensive nature, poor working and living conditions, and physical proximity required by
many construction tasks (Pasco et al., 2020). Unfortunately, it was found that few previous
CHM studies have focused on biological hazards exposed to construction workers (shown as
Figure 7). With the pandemic outbreak of the new coronavirus (COIVD-19) globally, more
attentions should be paid to the biological health interventions such as social distancing and
other healthy protocol (e.g., wearing a face mask, limits number of workers onsite and
disinfecting shared equipment) to curve the spread of coronavirus among construction
workers. Although the government and health organizations have issued guidelines to cope
with the impact of COVID-19 pandemic, it seems that no specific interventions are available
for construction industry(Amoah and Simpeh, 2020). In response to this gap, a robust spread
model of COVID-19 among construction workers considering different mitigation procedures
should be established and empirically verified to identify effective solutions for project
managers (Araya, 2021). In addition, considering workersincreased psychological stress
during this pandemic (Xiong et al., 2020), some protective psychological factors like
mindfulness, resilience and psychological capital, need to be further studied to help workers
combat negative psychological issues during the pandemic period (Chen et al., 2017b;Leung
et al., 2016a;Yuan et al., 2018).
6. Conclusions
In the past decades, numerous CHM studies have been conducted in order to understand the
characteristics of occupational health issues among construction workers and propose
feasible mitigation measures. However, there is still lack of a comprehensive review to
summarize the existing CHM studies. This research employed a systematic approach
consisting of bibliometric research (e.g., co-occurrence analysis, co-citation analysis) and an
in-depth content analysis to review 753 CHM-related articles collected from Web of Science
core database from 1990 to 2020. This research could provide researchers and practitioners
with a holistic understanding of the intellectual structure in CHM research, and identify the
emerging trends to guide future research directions.
Bibliometric review showed that CHM research has been increasingly popular among
researchers, with a constantly growth in the number of publications over the investigative
period. The USA was found to be the predominant country in CHM research. In addition,
Hong Kong Polytechnic University and Harvard University were two most productive
institutions, and two academic groups were identified in this domain according to cooperative
relationship among these institutes. American Journal of Industrial Medicine was the most
influential journals in the CHM research. Keyword analysis revealed the most frequent
keywords, including musculoskeletal disorders, ergonomics, posture, low back pain, which
are grouped into three clusters, which were associated with physical health, psychological
health and epidemiology investigation, respectively.
Content analysis obtained the publication distribution of five health hazards, four levels of
analysis and identified 17 research topics which were beneficial to understand the structure
and temporal evolution of CHM research. Then, three emerging trends were revealed,
including: increasing diversity of research topics; increasing application of innovation
technologies; increasing concern of workerspsychological health. The corresponding
research gaps were discussed namely: lack of clear definition of health management system;
lack of wide adoption of innovation technologies; lack of multilevel behavior-driven health
research; lack of effective biological health interventions. A set of research agenda was
provided to guide future research directions.
ECAM
This research is the first to highlight the issues of occupational health management from
the perspective of construction workers. Researchers would follow the recommended
directions to fill the research gaps and extend the body of CHM knowledge domain.
Nevertheless, the findings are to be considered in light of certain limitations. First, the
analysis was based on limited literature samples published in Web of Science core collection
and only English journal articles were included due to a consistent data format required by
the bibliometric techniques. It might have potentially excluded some latest studies in other
languages and literature types, and those studies merely published in other databases such
as Scopus. In the future, more comprehensive data can be collected by combining data from
various sources to fully assess the current status of CHM research.

The built environment (BE) sector has seen a significant digital transformation in the past few decades. While predictive analytics (PA) plays a critical role in such a transition. Applications of PA in the BE sector range from making a reliable prediction of the compressive strength of a given concrete mix design, forecasting cost for budget planning, to predicting the safety performance of construction projects. A few literature reviews have been published in related fields but do not provide a comprehensive state-of-the-art review of PA in the BE sector. To fully understand the applications of PA techniques in the BE sector, this study proposes a bibliometric analysis of extant literature. In this paper, a bibliometric analysis of 613 articles in the Scopus database from 2012 to 2021 was carried out to determine the leading knowledge formation entities (countries, institutions, authors, sources, and documents), critical research domains, and the current status of PA-BE research. The results showed that M Y Cheng is the most productive and influential author and China has emerged as the most productive and collaborative country. In terms of scientific impact (measured through average article citation), we observed France to be the most influential country. Through bibliographic coupling analysis, we observed that PA-BE research is presently clustered across four broad verticals: Action Recognition, Sustainability, Cost & Financial prediction, and safety. This paper developed a map of different predictive analytics methods with four clusters and provided PA-BE scholars with research gaps, suggestions and future research directions.
... According to Health and safety Executive (2021), the probability of construction practitioners dying from a work-related illness is more than 100 times higher than dying from a construction-related accident (Smallwood and Deacon 2020). Considerable research shows that workers of construction industry suffer from a large number of diseases including but not limited to musculoskeletal disorders, chronic obstructive pulmonary disease, contact dermatitis, noise-induced hearing loss, and mental illness (Chan et al. 2020;Dement et al. 2021;Dong et al. 2020;Liang and Shi 2022;Lie et al. 2016). ...
... Over the past few decades, considerable research studies have been conducted to investigate construction health, which lays the groundwork for improving health performance in the construction industry (Hwang et al. 2018;Liang and Shi 2022). However, existing research have largely focused on the mental health of construction practitioners or the specific physical diseases they suffer from (Chan et al. 2020;Dabirian et al. 2020;Dong et al. 2020;Jonsson et al. 2019). ...

Health climate is critical for achieving a better health performance in building construction projects. However, the topic is rarely investigated by extant literature. The aim of this study is to identify key determinants of health climate in building construction projects. To achieve this goal, a hypothesis was established between practitioners’ perceptions of health climate and their health status, based on a comprehensive literature review and structured interviews conducted with experienced experts. Then, a questionnaire was developed and administered for data collection. Partial least-squares structural equation modeling was used for data processing and hypothesis test. Results showed that health climate in building construction projects is positively correlated with the health status of the practitioners, and that employment involvement was the most important determinant of health climate in building construction projects, followed by management commitment, and supportive environment. Moreover, significant factors under each determinant of health climate were also disclosed. As limited research has been conducted to examine health climate in building construction projects, this study bridges the knowledge gap and is a contributory work to the current body of knowledge of construction health. Additionally, the findings of this study can provide authorities and practitioners with a deeper understanding of construction health and thereby helping them bring forward more feasible measures to improve health in building construction projects. Thus, this study is useful to the practice as well.

... Musculoskeletal disorders (MSDs) are a group of painful disorders of soft tissues (muscles, tendons, nerves, joints, cartilage, and ligaments) [1]. For construction workers, the prevalence of work-related musculoskeletal disorders (WMSDs) is very high worldwide [2]. What is worse, WMSDs are the leading cause of disability among construction workers [3]. ...

Training construction workers in safe postures for their tasks could help them avoid unsafe postures and reduce work-related musculoskeletal disorders (WMSDs). This study compared two forms of atlas design in facilitating workers’ learning postures, including their differences in guiding workers’ attention allocation and cognitive load during the learning process. One kind of atlas graphically shows the correct postures to perform construction tasks, and the other adds wrong demonstrations alongside the right ones. Eye-tracking technology was utilized to measure attention allocation and cognitive load. An experimental study was conducted, with 52 construction workers being invited as participants. The results indicated that workers significantly distributed more attention to diagrams than texts and more attention to diagrams showing execution postures than preparatory postures. Moreover, the workers had significantly longer fixation durations on the key body parts when there were wrong demonstrations, which ultimately improved their learning outcomes. There were no significant differences in cognitive load. Suggestions for designing an instructional atlas to enhance construction workers’ occupational health education can be obtained from the findings, including applying diagrams more instead of texts to describe how to correctly perform construction tasks, emphasizing the importance of preparation posture when performing construction tasks, and adding wrong demonstrations showing consequences, with visual cues being positioned on the key body parts.
... These include: cost estimators (Leung et al., 2008;Xiong et al., 2015); project managers (Haynes and Love, 2004;Leung et al., 2009); various construction professionals (Leung et al., 2017;Bowen et al., 2021;Wang et al., 2022); construction workers (Liang et al., 2018;Jebelli et al. 2019;Ahmed et al., 2022); and migrant workers (Palaniappan et al., 2022). Design professionals such as architects, interior designers, landscape designers and various types of engineering designers are conspicuous by their absence from this literature (Nwaogu et al., 2020;Liang and Shi, 2022), although Bowen et al. (2021) revealed that architects tend to suffer anxiety more frequently than other professional groups and this can be related to the creative and iterative nature of the work they perform which often conflicts with the linear approach to project planning and extreme time pressures imposed on design professionals to deliver in fast-tracked project programs which seek to overlap design and construction processes. Karklins and Mendoza (2016) also highlighted numerous job-related risk factors which uniquely contribute to the declining mental health of practicing architects and other designers compared to other construction professional groups, including: low fees; disempowerment in dominant procurement methods such as design and build; project time pressures imposed on the design phase to get projects started often with incomplete designs; long work hours; precarious employment; poor leadership; low fees; low influence; and unhealthy organizational cultures. ...
... Based on a systematic analysis of the potential terms, a three-level keyword structure, adaptively modified from Liang's search strategy (Liang and Shi, 2021), was adopted to cover diverse and large-scale search terms for comprehensively and reliably obtaining CWISC-related articles (as shown in Table 1). The context keywords defined the search context, which was limited to the construction industry; the topical keywords further narrowed the search scope; and the subject keywords limited the search subject to construction workers. ...

Existing studies have highlighted the importance of informal safety communication among workers at construction sites. However, there is still a lack of empirically tested theoretical models with valid and reliable scales for describing and measuring construction workers’ informal safety communication (CWISC). Accordingly, this study aimed to fill this need by developing an instrument to assess the communication performance of construction workers. Four stages of scale development were described: construct formation, item generation, factor extraction through the exploratory factor analysis (EFA) (n = 219), and scale assessment through the confirmatory factor analysis (CFA) (n = 156). Using questionnaire data drawn from construction workers in China, the CWISC was verified to be a three-dimensional construct including citizenship safety communication (CSC), self-needed safety communication (SSC), and participatory safety communication (PSC). The corresponding CWISC scale with 12 items was shown to have acceptable internal consistency reliability, as well as content, convergent, and discriminant validity. The CWISC scale could serve as an instrument to assess and identify the weaknesses in informal safety communication performance of construction workers. In turn, this information could help supervisors implement appropriate management practices to those workers to enhance workplace informal safety communication. Related studies taking a multidimensional CWISC into account were expected to be carried out.
... Sub-topic analysis 2.2.2 Content analysis. Bibliometric analysis is an important tool to assess academic output, but it does not give detailed information about the contents of the subject of interest (Esen et al., 2020;Liang and Shi, 2021). Therefore, in order to acquire an in-depth understanding of the topics discussed by researchers in the selected articles, content analysis was used in this study. ...

Purpose: The COVID-19 pandemic has brought profound changes to all sectors of society including the construction sector. The main purpose of this study is to explore and provide insights into the impact and changes that have occurred in the construction sector due to COVID-19 and to present a mitigation framework to minimize the effects. Design/methodology/approach: The scope of this study is limited to peer reviewed articles in Scopus or Web of Science indexed journals. A systemized review was performed with bibliometric and content analyses of articles related to the impact of COVID-19 on the construction sector. Findings: Through content analysis, the main topics discussed in the selected articles were grouped into 10 categories. Most of these studies were found to have focused on the challenges, impact, and health and safety at construction sites resulting from the pandemic. The study further identified 39 sub-topics through detailed content analysis and organizes them into the categories of negative impacts, positive impacts and opportunities, and barriers to COVID-19 safety guidelines in the construction sector. Moreover, the study developed a systematic mitigation strategy based on the recommendations of the literature review to reduce the impact of the current pandemic on the construction sector. The mitigation strategy presents separate set of measures regarding safety guidelines, process improvements, government intervention, psychological support, and technology adoption. Originality/Value: The research insights provided in this study are useful for practitioners in guiding them to design effective strategies for addressing the challenges of the COVID-19 pandemic and future crises. Furthermore, a systematic presentation of the impacts, challenges, and mitigation measures in this study will help researchers to identify existing gaps in the literature and explore other aspects of the impact of the pandemic on the construction sector.
... Thus, this study introduces HSP in the analysis of the GCPs-CS relationship. Furthermore, studies have revealed that the strength and direction of the effect of HSP on CS could differ depending on the level of GCPs adopted (Wuni et al. 2019), but more empirical details are needed to further validate and verify this claim with a view to providing a clear perspective on how this occurs on construction projects (Liang and Shi 2021). Hence, in order to contribute theoretically to existing literature, this study considered GCPs as a moderator in the relationship between HSP and CS. ...

Studies have proven that client satisfaction (CS) is greatly affected by the nature of construction practices on site. However, not much attention has been given to CS in projects that adopt green construction practices (GCPs). This study examines the effect of GCPs on CS and the means by which CS can be achieved through health and safety performance (HSP). This study also analyses how the relationship between HSP and CS could vary depending on the level of GCPs adopted. A questionnaire with 27 items drawn from literature was used in collecting data from class A contractors in Nigeria. The study’s hypotheses were tested using the partial least squares structural equation modeling (PLS-SEM) technique. The findings of the study reveal that GCPs have a positive effect on CS. HSP proved to only partially mediate the relationship between GCPs and CS. The findings also show that the effect of HSP on CS is moderated by GCPs with the stronger effect from projects with low adoption of GCPs. The study’s findings highlight the pivotal role of HSP in ensuring CS in construction projects that adopt GCPs. This study makes practical contributions to the body of existing knowledge by highlighting the need for concerted efforts by contractors such as investing in health and safety training and ensuring site workers wear personal protective equipment aimed at adhering to acceptable health and safety standards. This can be achieved through the provision of funds for safety activities, monitoring, and supervision of workers to guarantee HSP which translates to CS while adopting GCPs. However, the obstacles to these are the lack of safety culture by construction organizations, lack of enlightenment on the part of construction site workers, and poor safety climate on the construction project site. Additionally, the study provides greater insight into the practice of green construction among contractors by showing that the effect of HSP on CS would differ considerably on account of the level of GCPs adopted.

Purpose This paper aims to explore the influence of social support and the repatriation intention of expatriates in international constructions in the postpandemic era of COVID-19. Furthermore, test the mediation effect of team climate and individual resilience in this relationship. Design/methodology/approach A survey of 347 expatriates in international construction projects was conducted. A cross-level chain mediation model was employed to test the moderating effect of social support and repatriation intention. Then, statistical analysis with a bootstrap sample was used to test the mediation effect of the model. Findings The empirical results support that team climate, individual resilience and the chain mediating effect of team climate to individual resilience is significant among the influences of social support on repatriation intention. Social support can enhance the team climate of construction expatriates, promoting their resilience to reduce the repatriation intention further. Practical implications This study provides guidelines for international construction enterprises and managers to decide when and which expatriates should return home and formulate a series of policies to support expatriates and maintain a good team climate. Originality/value This study contributes to expatriate management literature by establishing the relationship between social support and repatriation intention. It provides a better understanding of how team-level factors impact individual thought. It takes team climate as one of the protective factors affecting individual psychological resilience. Also it takes social support as the antecedents of team atmosphere in case of emergencies.

Material-cart handling can be strenuous and lead to overexertion injuries. The aim of this study is to produce a thorough understanding of how the cart condition, tire type, physical environment-related factors, and load interact to influence the ergonomics and productivity of cart handling. Eighteen roofing carts with different conditions, tires, and loads were tested by one subject on three laboratory tracks: one L-shaped, one with ramps within constrained spaces, and one with obstacles within constrained spaces. A multiple linear regression analysis was performed to quantify the main and interaction effects of the factors of interest on the cart operations. The research findings confirm that using aged carts increases the injury risk by as much as 30.5% and decreases productivity by 35.4%. Our study also highlights the necessity of keeping an open space for cart operation; the travel distance from a cart to a ramp/obstacle should be greater than 61 cm. Finally, the results suggest the at-risk thresholds for different ramp slopes and obstacle heights, and the safe load capacities for the various working circumstances that are common on construction sites. The evidence created in this study can be translated into administrative controls for cart handling to reduce overexertion injuries and enhance performance.

Importance Policy makers have relaxed restrictions for certain nonessential industries, including construction, jeopardizing the effectiveness of social distancing measures and putting already at-risk populations at greater risk of coronavirus disease 2019 (COVID-19) infection. In Texas, Latinx populations are overly represented among construction workers, and thus have elevated rates of exposure that are compounded by prevalent high-risk comorbidities and lack of access to health care. Objective To assess the association between construction work during the COVID-19 pandemic and hospitalization rates for construction workers and the surrounding community. Design, Setting, and Participants This decision analytical model used a mathematical model of COVID-19 transmission, stratified by age and risk group, with construction workers modeled explicitly. The model was based on residents of the Austin–Round Rock metropolitan statistical area, with a population of 2.17 million. Based on 500 stochastic simulations for each of 15 scenarios that varied the size of the construction workforce and level of worksite transmission risk, the association between continued construction work and hospitalizations was estimated and then compared with anonymized line-list hospitalization data from central Texas through August 20, 2020. Exposures Social distancing interventions, size of construction workforce, and level of disease transmission at construction worksites. Main Outcomes and Measures For each scenario, the total number of COVID-19 hospitalizations and the relative risk of hospitalization among construction workers was projected and then compared with relative risks estimated from reported hospitalization data. Results Allowing unrestricted construction work was associated with an increase of COVID-19 hospitalization rates through mid-August 2020 from 0.38 per 1000 residents to 1.5 per 1000 residents and from 0.22 per 1000 construction workers to 9.3 per 1000 construction workers. This increased risk was estimated to be offset by safety measures (such as thorough cleaning of equipment between uses, wearing of protective equipment, limits on the number of workers at a worksite, and increased health surveillance) that were associated with a 50% decrease in transmission. The observed relative risk of hospitalization among construction workers compared with other occupational categories among adults aged 18 to 64 years was 4.9 (95% CI, 3.8-6.2). Conclusions and Relevance The findings of this study suggest that unrestricted work in high-contact industries, such as construction, is associated with a higher level of community transmission, increased risks to at-risk workers, and larger health disparities among members of racial and ethnic minority groups.

As the spread of COVID-19 has continued since December 2019, stay at home orders around the globe have changed how we live our lives, mostly from physical to virtual interactions, such as going to college and doing our jobs; however, some activities are basically impossible to perform virtually, such as construction activities. Thus, the construction sector has been highly disrupted by the current pandemic. The construction sector represents a key component of countries’ economies—it is approximately 13% of global GDP—as such, having the availability to perform construction activities with a minimum spread of COVID-19 may help to the financial response to the pandemic. Given this context, this study aims to understand the potential impact of COVID-19 on construction workers using an agent-based modeling approach. Activities are classified as being of low-medium–high risk for workers, and the spread of COVID-19 is simulated among construction workers in a project. This study found that the workforce from a construction project may be reduced by 30% to 90% due to the spread of COVID-19. Understanding how COVID-19 may spread among construction workers may assist construction project managers in creating adequate conditions for workers to perform their job, minimizing the chances of getting infected with COVID-19.

Background: As a major virus outbreak in the 21st century, the Coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented hazards to mental health globally. While psychological support is being provided to patients and healthcare workers, the general public's mental health requires significant attention as well. This systematic review aims to synthesize extant literature that reports on the effects of COVID-19 on psychological outcomes of the general population and its associated risk factors. Methods: A systematic search was conducted on PubMed, Embase, Medline, Web of Science, and Scopus from inception to 17 May 2020 following the PRISMA guidelines. A manual search on Google Scholar was performed to identify additional relevant studies. Articles were selected based on the predetermined eligibility criteria. Results: Relatively high rates of symptoms of anxiety (6.33% to 50.9%), depression (14.6% to 48.3%), post-traumatic stress disorder (7% to 53.8%), psychological distress (34.43% to 38%), and stress (8.1% to 81.9%) are reported in the general population during the COVID-19 pandemic in China, Spain, Italy, Iran, the US, Turkey, Nepal, and Denmark. Risk factors associated with distress measures include female gender, younger age group (≤40 years), presence of chronic/psychiatric illnesses, unemployment, student status, and frequent exposure to social media/news concerning COVID-19. Limitations: A significant degree of heterogeneity was noted across studies. Conclusions: The COVID-19 pandemic is associated with highly significant levels of psychological distress that, in many cases, would meet the threshold for clinical relevance. Mitigating the hazardous effects of COVID-19 on mental health is an international public health priority.

Purpose – The COVID-19 pandemic drastically changed safety measures in every industry, including the construction industry. Thus, the construction companies have instituted safety measures at the construction sites to curve the disease’s spread among the workforce. This paper aims to examine the challenges encountered by construction firms in implementing COVID-19 safety measures at construction sites. Methodology – A qualitative research approach was adopted for this study using open-ended interview questions to solicit data from 19 construction professionals currently working on a construction project in South Africa. Content analysis with the assistance of an Excel spreadsheet was used to analyse the data collected. Research limitations – The interviewees were construction professionals working in the South African construction industry during the COVID-19 period. Findings – The findings indicate that there are numerous challenges such as ignorance of COVID-19, the supply of poor personal protective equipment (PPEs) by contractors, lack of compliance, sanitising construction materials, difficulty in sharing tools and equipment, public transport usage by workers, superstition (COVID-19 is for a particular group of people), complying with social distancing rules, among others in the implementation of the COVID-19 safety measure at the construction site to curb the spread of the disease among the workers. These challenges have, therefore, hampered their effort to strictly adhere to the safety measures in accordance with the COVID-19 safety protocol at the project sites currently under construction. Implications – The implication is that, due to the challenges faced in implementing the COVID-19 safety measures, workers on the construction site are not adequately protected from contracting COVID-19. The workers may thus contract the disease at the project sites and transmit it to their families and vice versa, which may have further implications on the spread of the disease within the communities and society. Originality/value – The study has identified implementation challenges of the COVID-19 safety measures at construction sites of which the construction stakeholders must institute measures to overcome since COVID-19 has become part of our daily life. The study also recommends some preventive measures to the owners of construction companies to help overcome or minimise these COVID-19 safety implementation hurdles to minimise the spread of the disease among the construction site workers.

Background: Musculoskeletal disorders (MSDs) and opioid use are a combined burden for construction safety and health. This study examines both issues among construction workers using a large population-based survey. Methods: The prevalence of MSDs in construction was estimated using multi-year data from the Medical Expenditure Panel Survey. Prescription opioid use among workers with MSDs was compared to those without MSDs. Results: About 34% of construction workers had at least one MSD symptom. Compared to those without MSDs, prescription opioid use tripled (aOR = 3.28, 95% CI: 2.44-4.41) among construction workers with MSDs. Conclusions: MSDs are prevalent among construction workers, and prescription opioid use significantly increased among workers with MSDs. It is critical to adopt ergonomic solutions in construction to reduce MSDs, and support workers in injury recovery with effective pain management.

The adoption and implementation of innovative solutions is an effective means to improve construction safety performance. The use of technology as a preventive tool for stemming the observed disproportionate rate of worker injuries and fatalities in the construction industry as compared with other industrial sectors has gained substantial attention over the last two decades. Previous studies have highlighted the need to advance the state of knowledge regarding the usefulness and utility of technologies for safety and health management in construction as well as factors that limit and prevent technology use in the construction industry. This paper aims to fill this gap in knowledge and practice by (1) identifying technologies used for safety and health management in the construction industry and assessing the current rate of use within the construction industry; (2) highlighting the benefits and limitations of using technologies for safety and health management, and (3) identifying the critical barriers to adopting technologies for safety and health management and propose strategies to overcome such barriers. To achieve the research aims, a survey was conducted to collect relevant data on the topic. 102 construction practitioners with pertinent knowledge of technology as it is used within their organization responded to the survey. Results of the study suggest that although slight increase in technology for safety and health management in construction adoption and use transpired due to technology ability to improve safety conditions, a notable resistance regarding its continuous use remains an issue across the industry. The study findings provide invaluable information for industry practitioners and researchers regarding limitations of technology implementation and barriers of technology adoption as well as strategies to overcome such limitations and barriers. Overcoming technology implementation limitations and adoption barriers is expected to enhance the adoption of technology for safety management in the construction industry.
