Abstract
One of the factors of high number of accidents in construction industry is due to the lack of
safety management that is closely related to the poor safety awareness among stakeholders.
Previous studies had emphasized the role of stakeholders in affecting entire project
performance. This paper aims to investigate the significant factors affecting safety
management implementation at construction sites based on the perceptions of different
construction stakeholders. A total of 112 questionnaires was received from respondents of
various construction stakeholders such as consultants and contractors who are working at
construction sites in Johor Bahru. The factors affecting safety performance that formed the
questionnaire are commonly accepted physical safety management performance factors that
were derived from previous studies involving accident rates and the satisfaction of construction
stakeholders. An average mean index analysis was conducted, and the result indicated that
proper handling of equipment, proper installation and dismantling of heavy devices, and site
inspection and supervision conducted by supervisors closely contribute to the factors affecting
safety management at the construction sites. Further analysis on the similarity/dissimilarity
perceptions on the factors affecting safety management at construction sites for within
(Intraclass-Correlation Coefficient (ICC)) and between (Kruskal-Wallis) groups of respondents
were analysed. The findings of the present study revealed a high similarity of OSH risk
perception within and among stakeholder groups. This paper offers an important contribution
by providing significant information that benefits the construction stakeholders to further
facilitate the benchmarking process and various initiatives that can improve the safety
performance of construction industry as a whole.
Keywords: Construction; safety performance; safety management; safety performance factor.
INTRODUCTION
Construction is a major industry that has become the main focus today but remains
plagued with constant challenges, such as accidents and death. Laws and regulations have
been introduced to establish a good quality of safety management in many countries (Mehta
and Agnew, 2010). However, the number of accidents is still high in construction industry,
which has resulted in negative impacts in terms of reputation and safety performance.
Various construction projects are being undertaken at an increasing rate and complexity,
which influence workplace safety management. In 20002009, the Social Security
Organisation (SOCSO) reported a total of 42,775 accidents in the construction industry in
Malaysia, with an average annual mean incident of 19.3 per 100,000 by sector (Ganesh and
Krishnan, 2016). The most critical causes of accidents in the construction industry are falls,
specifically being hit by falling or moving objects (17%) and falling from height (28%)
(Ganesh & Krishnan, 2016).
MCRJ Special Issue Vol. 13 | No. 2 | 2021 69
The construction sector has earned a negative reputation due to its high accident rates.
The rates of fatal and non-fatal injuries and illnesses are relatively high and have not dropped
significantly during the past 10 years (Abudayyeh, Frederick, Butt & Shaar, 2006). These
problems in safety management are affected by the ‘poor safety awareness among
stakeholders, lack technical guidance and lack of supervision to monitor the reckless
operations’ (De Silva, Rajakaruna & Bandara, 2008).
Stakeholder management has a considerable influence on construction projects
(Loosemore, 2006). Ng, Cheng & Skitmore (2005) stated that it is an extra advantage for
stakeholders to involve in the small-scale construction projects, which require low-quality
standards, low cost and minimum time, thereby regarding safety as the lowest priority. The
factors listed in this research are human, equipment, management and technical factors, which
strongly prove that stakeholders have a poor record in safety management.
Factors affecting safety management have been researched by Kanachana and
Karunasena (2018), Yiu, Sze and Chan (2018), Zhao, Kazemi, Liu and Zhang (2018) and
Tam, Zeng and Deng (2004), but their studies were conducted in countries other than
Malaysia. Several studies have been published in the form of journals, theses, books and
online data indicating the safety factors involved. In Malaysia, there is a lack of research in
this field, and the perceptions of construction stakeholders have not been examined despite
the several case studies that have been made.
Stakeholders substantially influence project complexity and interactions. According to
Salancik and Pfeffer (1974), stakeholders are a major factor affecting the entirety of project
performance. This statement was underlined by Yang and Shen (2014): stakeholders have the
power of compromise and adaption in project strategies. Project outcomes can indicate the
influence of the stakeholders in project making (Aaltonen & Sivonen, 2009) and the project
phases (Herazo & Lizarralde, 2016).
Therefore, this study intends to investigate the significant factors affecting safety
management at construction sites from construction stakeholders’ perspectives. Furthermore,
the collected data were examined for any similarity in perception about these factors.
LITERATURE REVIEW
Construction Safety Management
Construction safety management deals with the actions of the management in all
organisational levels to create a structured organisation platform with which employees are
going to be trained and motivated to perform safe and productive construction work (Hassan
et al., 2009; Levitt & Samelson, 1993). In addition, safety management is an effective system
of removing and minimising the forces that injure workers and damage facilities and
equipment at construction sites. Therefore, safety management is an organisational function
that identifies safety risks to ensure safety (Jokkaw & Tongthong, 2016).
Project site safety is related to the process of safety management in terms of controlling
safety policies, procedures and practices. According to Cheng, Li, Fang and Xie (2004), the
desired goals can be achieved through a dynamic process. However, Ming (1994) concluded
MCRJ Special Issue Vol. 13 | No. 2 | 2021 70
that safety, health and environments should first be managed in all aspects of a construction
business to manage safety management systems, such as policies, organisations, management
controls and resources.
Moreover, the actions of engineers, contractors and subcontractors influence jobs at
construction sites. Among these important personnel, engineers should be the most ethical;
they should prioritise safety and health at construction sites. According to Hinze and Raboud
(1988), the intervention of top management can help reduce accident rates. This finding
supports the view of Heinrich’s Domino Theory, in that 98% of accidents can be prevented
through the involvement of safety management. Heinrich’s theory can be the platform on
which monitoring systems can be started and feedback on effective safety management can
be provided (Chi & Han, 2013).
Contractors and subcontractors in the construction industry tend to ignore the safety
management requirements stated in standards produced by OSHA and legislations (Bakri,
Zin, Misnan & Hakim, 2006). This is supported by Abdullah and Chai (2010) who suggested
that it was the employer’s negligence that was responsible for the occurrence of accidents
within the construction sector. According to Lingard and Rowlinson (1997), subcontractors
do not prioritise the importance of worker safety and violate safety practices to ensure
adherence to project schedules. Although the subcontractors in Lingard and Rowlinson’s
study are from small to medium sized company, some subcontractors do not implement safety
management at construction sites to stay within the budget of the contracting company. In
addition, they also found that subcontractors have poor safety awareness and do not
communicate sufficiently with the workers at their construction sites due to the unavailability
of safety resources on these sites.
A successful safety management plan of action must be underpinned by the commitment
of top management; such support is essential for reducing the accident rates at construction
sites. In addition, management systems have been introduced into industrial undertakings
(Bakri et al., 2006). The application of safety management systems should be clear to identify,
understand and control injury hazards and reduce incidents. The implementation of safety
management requires employers to conduct daily inspection to create awareness and show the
advantages of safety management systems. Therefore, this study adopted the framework of
Zhao et al. (2018), whose findings outlined safety management supervision under the five
significant factors.
Factors Affecting Safety Management
The factors affecting safety management implementation at construction site are
discussed by category.
Human Factors
Human factors include the human activity involved in the operation, production or
construction of equipment and systems. According to Garrett and Teizer (2009), ‘human has
the strong relationship influence each other in the same work of environment situation’. This
statement is supported by the finding that 88% of accidents are caused by human factors
(Heinrich & Peterson, 1931). Catastrophic accidents are caused by human factors (Bridges &
MCRJ Special Issue Vol. 13 | No. 2 | 2021 71
Tew, 2016). The deficiencies in these factors include the safety attitudes of workers (Hassan,
Chew & Chandrakantan, 2009; Siu, Philips & Leung, 2003) and supervisors (Fang, Wu &
Wu, 2015; Kanachana & Karunasena, 2018) and lack of safety training received by workers
(Olutuase, 2014), effective communication and cooperation (Zin & Ismail, 2012; Zohar
(2002), safety experience and skills of contractors and supervisors (Ghani, hamid, Zain,
Rahim, Kamar & Rahman, 2010; Wong, Chan, Tse & Love, 2000) and site safety inspection
and supervision conducted by supervisors (Fang et al., 2015; Choudry & Fang, 2008).
Equipment Factors
Equipment factors are dangerous because they involve human beings working with
machines to complete tasks. According to the National Bureau of Statistics, mechanical
equipment causes five major injuries to humans, namely, falling injuries, crane machine
accidents, object strikes, electric shocks and collapse. The key factors that must be properly
selected and used according to standard operation procedures to reduce life-threating
situations are personal protective equipment (PPE) (Zin & Ismail, 2012; Guo, Li, Chan &
Skitmore, 2012), proper installation and dismantling of heavy devices (Beavers, Moore,
Shapira & Lyachin, 2009) and proper handling of equipment (Teo, Ling & Chong, 2005).
Environmental Factors
Environmental factors influence the performance of a project and involve the lack of good
knowledge about successful safety management. Akanni, Oke and Akpomiemie (2014) stated
that the environmental factors in safety management should be taken into account in
managing the development of construction sites to reduce unpredictability and add potential
effects. This is also supported by Kartam, Flood and Koushki (2000) that adverse weather
condition is one of the causes that forbid construction stakeholders to actively pursue effective
ways to maximize the achievement of safety goal.
Management Factors
Management factors refer to the failure of the management in all organisational levels to
promote workplace safety performance through safety management. Any organisation
management that fails to promote safety management might contribute to management
factors. The key elements influencing the management factors of safety management are
safety meetings (Tam, Fung & Chan, 2001), safety management commitment (Michael,
Evans, Jansen & Haight, 2005; Baxendale & Jones, 2000), health and safety files (Baxendale
and Jones, 2000), safety regulation and plan enforcement (Baxendale & Jones, 2000; Ning,
Wang & Ni, 2010; Tan and Nadeera, 2104 2014?), budget allocated for safety management
(Tan & Nadeera, 2104) and safety management systems that adhere to legislations, codes and
standards (Bakri et al., 2006; Kartam, Flood & Koushki, 2000).
Technical Factors
Technical factors refer to the improper handling of equipment and the use of wrong
techniques by workers at construction sites (Abdul Hamid, Yusuf & Singh, 2008). The key
elements of the technical factors influencing safety management are safety risk identification
and analysis (Malekitabar, Ardeshir, Sebt & Stouffs, 2016; Choe and Leite, 2016), first aid
MCRJ Special Issue Vol. 13 | No. 2 | 2021 72
training and emergency preparedness (Ali et al., 2012), complexity type of construction
(Suraji et al., 2001) and behaviour-based safety techniques (Oostakhan, 2012; Tavakol &
Dennick, 2011).
METHODOLOGY
The factors affecting safety management implementation were obtained through a
literature review of published journals, theses, books and internet articles published from the
year 2000 to 2019. Next, the obtained data that relevant were selected and collated on the
basis of the identification of the factors affecting safety management implementation at
construction sites. The researcher designed the questionnaire by incorporating the five factors
influencing safety management at construction site, i.e. human, technical, management,
environmental and equipment factors.
Next, the questionnaire was reviewed by 3 panels of expert to validate and check the
content reliability of its design. The experts were selected among those who had more than
10 years experience in managing safety and health at construction sites. The questionnaire
was revised several times regarding the importance of the collated attributes before being
distributed to the selected stakeholders. The authors solicited responses from several
construction sites throughout Johor Bahru. The data collected from the questionnaire were
analysed using analyses of the average mean index, intragroup (intraclass correlation
coefficient) and intergroup comparison (KruskalWallis) to measure the five factors that are
significantly related to construction safety management. Conclusions and recommendations
were made on the basis of the analysis findings.
Questionnaire Development
The data on the perceptions of multiple stakeholders at construction sites were collected
through questionnaires to enable an objective and cost-effective investigation. First, a
comprehensive list of safety factors was screened through a pilot study to ensure that all items
in the questionnaire were valid, reliable and significant. . The questionnaire contained two
sections. The first section explored the backgrounds of the respondents, and the second
section consisted of the 23 safety factors listed in Table 1. These are the factors that could
affect safety management at construction sites. The questionnaire adopted Likert scales
ranging from 1 (absolutely disagree) to 5 (absolutely agree).

Population and Sampling
The participants were the construction stakeholders who were fully involved in the
construction sites in the Johor Bahru area. The respondents were labelled ‘unknown
population sample’ due to the unknown exact number of them working in Johor. The
questionnaire was answered in a voluntary and anonymous manner with the strong support
and coordination of the project owners. In total, 120 questionnaires were distributed, and 112
valid questionnaires were retrieved (93.33% response rate). The 6.3% invalid questionnaires
either had incomplete answers or were not filled out by the respondents they were sent to.
Figure 1 shows pie charts of the respondents’ stakeholder type, designation type and working
experience.

Measures for Data Analysis
After the data collection, non-parametric methods were used to analyse the safety factors
affecting safety management implementation at construction sites. The data were analysed
with spreadsheets to estimate the mean value for the factors. The software Statistical Package
for the Social Sciences (SPSS) was utilised for the following techniques: (1) reliability test,
(2) intragroup comparison using the intraclass correlation coefficient and (3) intergroup
comparison using the KruskalWallis test.
MCRJ Special Issue Vol. 13 | No. 2 | 2021 74
Instrument for Reliability Test
A reliability test was conducted to check the reliability of the results and the overall
consistency of the entire survey. Cronbach’s alpha was used to measure the instrument’s
reliability (i.e. internal consistency). Factor analysis theory (Tavakol & Dennick, 2011)
indicates that an alpha value greater than 0.6 shows acceptable reliability. According to Koo
and Li (2016), good internal consistency is expressed by an alpha value of at least 0.70.
Average Index Analysis
Average index analysis was used to compute the mean scores of the significant factors
affecting safety management. The rating groups of the average indices that represented the
appropriate classification suggested by Majid & McCafer (1997) are shown in Table 2.
Table 2. Average Index Rating Group

Neutral
2.50 ≤ Average Value ≤ 3.50
Agree
3.50 ≤ Average Value ≤ 4.50
Strongly Agree
4.50 ≤ Average Value ≤ 5.00
Intragroup Comparison
An intragroup comparison was performed using the ICC test to identify any similarity or
difference within the groups regarding the safety factor in safety management. Specifically,
intraclass correlation measures the reliability of scales or measurements for clusters of data
collected or sorted into groups. As stated by Koo and Li (2016), an ICC less than 0.5 signifies
low similarity among the same group, 0.5 to 0.75 indicates moderate similarity, 0.75 to 0.9
indicates high similarity, and 0.9 indicates the most excellent similarity among the same
group.
Inter-Group Comparison
The purpose of inter-group comparison was to check whether there are similarities or
differences between and among the groups of stakeholders regarding the risk perceptions
related to all of the cases. The Kruskal-Wallis test was employed in the present study with the
aim of determining whether all of the four stakeholder groups as a whole had any
disagreements on risk perceptions. Next, the post-hoc test (Anova 1-way test) was carried out
to test the pairwise comparisons between stakeholder groups regarding any significant
discordance of risk perception regarding each scenario.
RESULTS AND DISCUSSION
The data were analysed using Microsoft Excel and SPSS. The outcomes from the software
provided the results for the reliability test, average mean index and intragroup and intergroup
comparisons, which are presented here in the form of tables.
MCRJ Special Issue Vol. 13 | No. 2 | 2021 75
Reliability of the Survey Instrument
A reliability test was done to ensure good internal consistency. The stakeholders involved
in this reliability test were technical/management, safety and design teams involved in the
construction sites. Table 3 shows the results of the reliability test for all groups of respondents,
which is 0.952. Therefore, the degree of agreement is uniformly reliable (high reliability)
(Cronbach & Shavelson, 2004, Koo & Li, 2016).

Average Index Analysis of the Survey Results
An average index analysis was performed to determine the significant factors affecting
safety management that were gathered through the given Likert scale. The results in Table 3
show that the design team has a higher mean rating score compared with the safety team. This
finding is in line with Zhao, McCoy, Kleiner, Mills and Lingard (2016), who stated that the
‘design team have lack of knowledge about hazards awareness involved at the construction
site’. Moreover, Ning et al. (2010) postulated that design teams have little responsibility on
the on-site practice and management, hence unconvinced about the factors. Meanwhile, the
safety team has the lowest mean rating score, probably because its members have a good
understanding of their responsibilities and ability to control the crucial safety factors
occurring at their construction sites. This result is in line with that of Zhao et al. (2016), who
stated that whoever controls the working environment directly influences the perception of
existing factors.

From Table 4, it could be seen that the most significant factor affecting safety
management implementation at construction site is EQF3 (proper handling of equipment),
followed by HF5, EQF2, HF6, HF3, MF7 and TF2. Meanwhile, the least factors perceived by
the stakeholders are ENF1, ENF2 and MF3. Design team tend to perceive most of the factors
(20 out of 23 factors) the highest compared to other stakeholder groups, whilst safety team
tend to perceive most of the factors (15 out of 23 factors) the lowest compared to other groups.
The findings also suggested that the mean of design team was greater than the mean of all
participants for all factors, except HF6 (effective communication and cooperation).
Meanwhile, the perceived factors of safety team was lower than the mean of all participants
for all factors.
It is interesting to note that all stakeholder groups tend to perceive 2 key items under
‘Equipment’ factor, which are EQF2 (proper installation and dismantling of heavy devices)
and EQF3 (proper handling of equipment), among the top 5 factors that influencing safety
management implementation at construction sites. According to Teo et al.(2005), proper
handling of equipment and other equipment-related factors are related to the process of
carrying out works by workers that may eventually be harmful to their safety and health. Some
organisations and individuals had committed to unsafe act unknowingly while carrying out
their tasks (Dedobbeler & Beland (1991), which may result in the difficulty in implementing
safety management at construction site. Therefore, all plant, tools and equipment should be
handled, maintained and repaired by qualified personnel (Teo et al., 2005).
Intragroup Comparison
The pairwise intragroup comparison among the technical/management, safety and design
teams was analysed using the ICC. Table 5 shows the results. The safety team has the highest
ICC regarding the factors affecting safety management (ICC = 0.958, p < 0.001). The ICC of
the technical/management team is 0.943, and the lowest ICC among these groups is that of
the design team, which is 0.940. Although the design team has the lowest value of ICC, its
value still indicates an excellent similarity (the value of the ICC demonstrates homogeneity
within a group). These results indicate a high mean perception among the teams.

Intergroup Comparison
The intergroup comparison was analysed using the KruskalWallis test to measure the
disagreement (if any) among these three groups of construction stakeholders as a whole
regarding the significant factors. The results of the pairwise intergroup comparison from the
KruskalWallis test demonstrate that all of the stakeholders perceive the factors
homogenously (p < 0.001). Meanwhile, a post hoc test (one-way ANOVA) was not needed
because no contradiction existed between the groups.
CONCLUSION
The current research presents an experimental study that investigated construction
stakeholders’ (technical/management, safety and design teams) perceptions of the factors
affecting safety management at construction sites. Twenty-three safety factors (human,
equipment, environment, management and technical factors) were investigated, and the
similarities and differences in the stakeholder groups’ perceptions were measured. The design
team had the highest mean score among all groups.
Furthermore, all of the stakeholders produced high, significant values (more than 0.005),
indicating that all of them perceive the factors homogeneously. Meanwhile, the SPSS findings
revealed that the design team was likely to give higher ratings compared with the other groups
of stakeholders because, as stated by Zhao et al. (2016), ‘design team focusing point is to
ensure the satisfactory of building performance in their design and calculation often lead to
uncertainties’.
The safety team had the lowest mean rating score, possibly because its members had a
good understanding of their responsibilities and ability to control the crucial safety factors
occurring at their construction sites. This is in line with Krallis and Csontos (2006), who stated
that ‘who control over the working environment will directly influence to perception of the
existing factors’.
The present study contributes to the existing body of knowledge in construction safety by
providing evidence of the similarities and differences in stakeholders’ perceptions,
particularly those who are site-based. The method employed in this study refers to previous
works but provides a new approach to investigating the factors affecting safety management
at construction sites.
In view of this, future research can be improved by detailing out the reason why each of
the stakeholder groups chose the provided rating for each factor. The goal is to identify
significant factors precisely, thus enhancing the safety management factors. Finally, future
studies should widen the research scope and increase the number of respondents by covering
different states in Malaysia.

Kuala Lumpur is a city characterized by a warm and humid climate throughout the year. Extreme rainfall occurrences and catastrophic floods in the city often have an impact on social, economic, and environmental structures. Rapid development and increase in population density caused the city more vulnerable to harmful consequences. The objective of this study is to estimate the return period and level of extreme rainfall in Kuala Lumpur. In this work, observed extreme rainfall of Kuala Lumpur was investigated over more than 30 years. The data were statistically analyzed using Generalized Extreme Value (GEV). Extreme rainfall assessment is viewed from the perspective of spatial analysis. Return periods of 20, 50, and 100 years of extreme rainfall showed an increasing trend. Four different rainfall aggregation periods considered in this study are 1, 3, 12, and 24 hours. At intervals of 20, 50, and 100 years, the spatial extreme rainfall distribution in Kuala Lumpur showed similar distributions for 1 hour to 24 hours. The three zones most vulnerable to flash floods caused by extreme rainfall identified: City Center, Damansara-Penchala, and Wangsa Maju-Maluri. Extreme rainfall analysis is crucial as it depicted the extreme rainfall behaviour in Kuala Lumpur for design planning purposes in sustainable urbanization and therefore devising strategies for future projected disaster risk.

... This proves that investigating latent relationships for the sub-factors is an important research area in the literature. Similarly, many studies focused on the latent relationships for a set of determinants specified (Fa et al., 2021;Kerry et al., 2021;Purushothaman and Seadon, 2020;Tang et al., 2022). However, as a major gap in the literature, far too little attention has been paid to determine the latent relationships among determinants that existed in different main factors. ...

Purpose This study aims to observe the impact of peripheral vision on construction safety. The study further intends to create awareness of eye diseases in construction safety, an important root cause for most construction-related hazards and accidents. Design/methodology/approach This study focuses on the impact of peripheral vision in terms of construction site safety. Experiments were conducted with construction employees with different qualifications, ages, expertise, and previous safety training experience. The experiments were conducted with an experiment set consisting of a tangent screen to measure the peripheral angle of the participants. The study measured peripheral vision, which helped determine the vision field accordingly. In this context, a total of 32 participants were investigated in terms of their peripheral visual angle and the field of vision. The data collected was analyzed in terms of several statistical tests such as One-Sample t-test, multivariate ANOVA, and multiple linear regression. Findings The results of the study indicated that there are significant differences in peripheral vision in terms of age of participants, work qualification, work experience, area of expertise, and previous safety training experience. The study further revealed that most of the participants failed to satisfy both OSHA requirements about peripheral vision, and normal limits defined in the previous literature. The study further implies that participants, who reported previous sight problems or eye diseases are more vulnerable to construction site accidents. Originality/value Construction site safety remains a major concern for most construction companies despite the latest developments in technology. Several companies are struggling with poor safety performance, occupational injuries and illnesses, and work-related accidents resulting in fatalities. However, the root causes behind several construction accidents are still vague due to different dynamics in the construction industry. Among these root causes, poor sight, vision, and or eye diseases constitute an important part. Hence, the study provides empirical evidence with the workers checked for eye health to help policymakers and industry practitioners in terms of developing awareness for eye-related injuries and accidents and review their safety programs accordingly.
... When workers lack adequate safety and health education, hazardous risk on construction sites may not be identified by the workers. Safety practices at work are vital in promoting safety amongst themselves on the construction site [30,31,32]. ...

The construction industry is known to be among the most vulnerable industries in terms of occupational safety and health. One of the riskiest activities in construction involves masonry, which reports several cases involving occupational health diseases due to the exposure to silica dust. Thus, this study aims to investigate the perception toward health risks due to exposure to dust in masonry work. A survey research method was adopted for this study, which involved the participation of 25 active construction contractors in Selangor and Kuala Lumpur. The findings reveal that respiratory problems and health diseases are the most perceived risks associated to dust exposure in masonry work. There are various barriers to the adoption of engineering control in masonry work such as high costs, lack of awareness of dust hazards, and workers’ attitudes. The current practical intervention methods used by contractor firms are respiratory protection, wet method, and sweeping compound. This study provides information on the current masonry work environment and the barriers of the adoption of engineering control technologies. Additionally, this study suggests that the key players in the construction industry should take an active part to increase the implementation of engineering controls in a construction project, and not rely solely on the use of PPE.

To deepen the understanding of the construction safety accidents rules as well as identify and cure the crux of construction safety management failures in China, we analyzed the status quo of safety management and identified the “last mile” problem, that is, the failure of implementation of the extensive legal and regulatory systems on the construction site. The safety factors were then extracted based on a questionnaire consisting of 34 items. Through factor analysis and ranking correlation, five human factors were found to be the greatest challenge and leverage point of safety management at construction sites. Accordingly, a novel safety management framework was proposed and tested as part of the Wuhan-Shenzhen highway project. Expert auditing confirmed that the proposed framework could substantially improve the construction safety performance and thus bridge the “last mile” of safety management implementation.

Introduction In the 1980s, the safety management system (SMS) was introduced in the construction industry to mitigate against workplaces hazards, reduce the risk of injuries, and minimize property damage. Also, the Factories and Industrial Undertakings (Safety Management) Regulation was introduced on 24 November 1999 in Hong Kong to empower the mandatory implementation of a SMS in certain industries including building construction. Therefore, it is essential to evaluate the effectiveness of the SMS in improving construction safety and identify the factors that influence its implementation in Hong Kong. Method A review of the current state-of-the-practice helped to establish the critical success factors (CSFs), benefits, and difficulties of implementing the SMS in the construction industry, while structured interviews were used to establish the key factors of the SMS implementation. Results Results of the state-of-the-practice review and structured interviews indicated that visible senior commitment, in terms of manpower and cost allocation, and competency of safety manager as key drivers for the SMS implementation. More so, reduced accident rates and accident costs, improved organization framework, and increased safety audit ratings were identified as core benefits of implementing the SMS. Meanwhile, factors such as insufficient resources, tight working schedule, and high labor turnover rate were the key challenges to the effective SMS implementation in Hong Kong. Practical applications The findings of the study were consistent and indicative of the future development of safety management practice and the sustainable safety improvement of Hong Kong construction industry in the long run.

A literature review of 16 papers on occupational injury research in Malaysia published during a 13-year period from 2000-2013 was carried out. The objective of this review and article selection was based on relevance to the research theme and mention of areas for future research. Most of the publications have focused on descriptive epidemiology, management practices, worker’s knowledge, attitude, training, and rehabilitation services. The transportation, agriculture and construction sectors were found to be the most hazardous sectors and would benefit the most from Occupational Safety & Health (OSH) research and interventions. There is a strong need to develop a national injury surveillance system and also a mechanism to ensure adherence to the Occupational Safety & Health Act(OSHA) 1994. Detailed description and identification of risk factors for occupational injury in the environment, including machinery and equipment used was generally lacking. Future research on occupational injury should focus on surveillance to determine the magnitude of occupational injuries, determination of risk factors, identifying costeffective interventions (such as enforcement of OSHA regulations), and assessment of rehabilitation services. Relevant government agencies, universities, corporate sector and occupational safety organizations need to play a proactive role in identifying priority areas and research capacity building. Funding for occupational injury should be commensurate with the magnitude of the problem.

Given the hazardous nature of the construction industry world over, the need for an effective safety management system which aims at forestalling the risks and hazards inherent on site has been reiterated by recent studies and applicable laws. Studies however show that level of effectiveness differs from country to country; industry to industry and from company to company. This study therefore undertakes both qualitative and quantitative investigation into the safety management system of a Nigeria-based construction company with a view of determining how compliant the system is to international standards. Identifying five major components and fifteen elements in the study, both primary and secondary data were collected through personal interviews, structured questionnaire and observation and these were analysed using One Sample t-test at 0.05 level of significance. The results show that though a form safety management system exists in the company, the system is however poorly organised and consequently, it is characterised by ineffectiveness and poor documentation. It is therefore recommended that management gives an urgent attention to the company's safety management system with an intense interest to standardise its operations and functionality. As a roadmap to achieving this, the paper proposes an integrated "PCR" safety model based on the "TAB" philosophy.

The construction industry has one of the worst occupational health and safety records of all industries. In recognition of this, several innovative safety techniques have been introduced to mitigate undesired events before they occur, including safety risk assessment. However, evaluation of safety risk is challenging due to the dynamic nature of the construction work environment and lack of reliable references. This study (1) compares safety risk of different construction trades in terms of common hazard types and sources of injuries, and (2) proposes safety risk quantification models by occupations, which can play a role as a safety reference for reliable safety risk assessment. Using occupational injury data, two relative injury indexes, relative fatality and relative days away injury indexes, were used to compare relative safety among 19 different construction occupations as well as the construction average. Each relative injury index of an occupation was further decomposed into hazard types, sources of injury, and injury scenarios. Based on comparative relative injury index data, a tree-based safety risk quantification model was proposed. The findings indicate each occupation has a unique pattern of safety data structure in terms of hazards and sources of injuries. In addition, the same occupation had different hazard types and sources of injury that can lead to different injury severities. A construction project typically involves numerous workers and resources. The safety risk analysis presented in this paper can be used as a general safety reference by safety managers to understand the dynamic nature of safety risk. It can also aid in preparing safety actions, such as inspections or training, more effectively by focusing on high-risk occupations, hazard types, or sources of injury.

Project stakeholders in the building sector adopt different approaches to sustainability, based on diverse definitions and perceptions of what is to be considered “sustainable” and the means to achieve it. These differences create tensions, which in some cases lead to better interventions and, in other cases, to conflicts. It is therefore crucial to understand these differences and examine both their theoretical and practical implications. Nonetheless, while attempting to do so, two problems often arise. First, scholars tend to classify stakeholders in groups, labelling them and oversimplifying their differences in power and the dynamic character of their approaches. Second, insufficient knowledge still exists on whether and how differences between stakeholders' approaches to sustainability influence building projects. The longitudinal and detailed analysis of the evolution of stakeholder decisions and tensions in a building project in Canada overcomes these two limitations. The study includes a comprehensive stakeholder analysis during early project phases, and the mapping and examination of the evolution of sustainability approaches. Results illustrate how differences in sustainability approaches influence the project process and its final outcome. They show that sustainability approaches are dynamic and create tensions that significantly impact the initial project goals and the planning and design phases. From a theoretical perspective, these results suggest a method to map the dynamic character of sustainability approaches. From a practical perspective, these findings can help clients, project managers and design professionals anticipate possible tensions and make informed choices, ultimately creating projects that better respect the environment and society.

Objective: Intraclass correlation coefficient (ICC) is a widely used reliability index in test-retest, intrarater, and interrater reliability analyses. This article introduces the basic concept of ICC in the content of reliability analysis. Discussion for researchers: There are 10 forms of ICCs. Because each form involves distinct assumptions in their calculation and will lead to different interpretations, researchers should explicitly specify the ICC form they used in their calculation. A thorough review of the research design is needed in selecting the appropriate form of ICC to evaluate reliability. The best practice of reporting ICC should include software information, "model," "type," and "definition" selections. Discussion for readers: When coming across an article that includes ICC, readers should first check whether information about the ICC form has been reported and if an appropriate ICC form was used. Based on the 95% confident interval of the ICC estimate, values less than 0.5, between 0.5 and 0.75, between 0.75 and 0.9, and greater than 0.90 are indicative of poor, moderate, good, and excellent reliability, respectively. Conclusion: This article provides a practical guideline for clinical researchers to choose the correct form of ICC and suggests the best practice of reporting ICC parameters in scientific publications. This article also gives readers an appreciation for what to look for when coming across ICC while reading an article.

This article presents a leadership-based intervention model designed to modify supervisory monitoring and rewarding of subordinates' safety performance. Line supervisors received weekly feedback based on repeated episodic interviews with subordinates concerning the cumulative frequency of their safety-oriented interactions. This information identified the priority of safety over competing goals such as speed or schedules. Section managers received the same information and used it to communicate (high) safety priority. They also were trained to conduct episodic interviews to provide intermittent feedback after intervention, turning safety priority into an explicit performance goal. Safety-oriented interaction increased significantly in the experimental groups but remained unchanged in the control groups. This change in safety-oriented interaction was accompanied by significant (and stable) changes in minor-injury rate, earplug use, and safety climate scores during the postintervention period.
