“…Strong commitment to safety measures by management will require sufficient financial and moral support. A study specified the optimal safety investment to be 1% of the total project value [ 103 ]. Furthermore, a study has identified the safety climate factor of safety management rules and regulations as the most effective safety factor [ 104 ].…”

Workers’ wellbeing and safety is important in the construction industry due to the high risk of accidents. Safety climate development is a positive initial step toward raising the safety levels of construction practitioners. This study aims at revealing the factors influencing safety climate perceptions in the construction industry of Saudi Arabia. A set of extracted factors from the literature was validated and used to design a comprehensive questionnaire survey. Data was collected from 401 personnel working on 3 large construction project sites in Saudi Arabia. Descriptive statistics and the crosstabulation algorithm, Kendall’s tau-b correlation test, were used to analyze the data. The study revealed a set of 13 factors influencing safety climate perceptions, which are: Supervision, guidance and inspection, appraisal of risks and hazards, social security and health insurance, workmate influences, management safety justice, management commitment to safety, education and training, communication, workers’ safety commitment, workers’ attitude toward health and safety, workers’ involvement, supportive environment, and competence. The results also indicate the significant and anticipated role of top management in safety climate at sites. Implications of this study include assisting construction industry stakeholders to better understand and enhance safety climate, which in turn will lead to improved safety behavior, culture, motivation, and performance.

“…Investments in safety must be formulated as preventive measures against fatal accidents (Shohet et al 2018). According to Shohet et al (2018), safety investments cover costs of equipment, training, insurance, and other personal costs related to construction activities. The investments in safety would lead to enhancement in safety performance (Lu et al 2016).…”

This study aimed to investigate the internal relationships between safety investments and construction employees' behavioral performance with safety cognition as the mediating factor. A comprehensive methodology was adopted, including theoretical modeling of safety investments, questionnaire survey, and Structural Equation Modeling (SEM). In the theoretical model, four factors (i.e., personal protection equipment (PPE), safety education, insurance purchased for site employees, and safety incentives) were adopted as safety investment categories. These four categories were studied of their correlation to the overall safety investment, which was tested of its contribution to employees' behavioral safety performance in both direct and indirect ways. Indirectly, safety cognition was introduced as a mediator to bridge safety investments and behavioral performance. A questionnaire consisting of 28 indicators was adopted to describe safety investment, safety cognition, and behavioral performance. A random sampling approach and the top-down method were implemented to recruit construction site employees from the southeastern region of China. The follow-up SEM analysis revealed that all the four investment categories positively contributed to the overall safety investment, which was found significantly correlated to employees' safety cognition and behavioral performance. Safety incentive was identified as the most significant factor contributing to the overall investment. The current study extends

“…After investigating 40 construction projects in progress, López-Alonso et al revealed that the number of accidents in the projects is negatively correlated with the level of safety investment [ 12 ]. Based on Monte Carlo simulation, Shohet et al found that increasing the safety investment of construction projects by 0.5%, from 0.5% to 1.0%, would result in a marginal benefit of 164,700 USD [ 33 ]. These findings verify the popular assumption.…”

“…Thus, to stay economically competitive and reach the maximum profits, many contractors have few motivations to invest adequately in construction safety [ 14 , 38 ]. A field survey conducted by Shohet et al on 30 construction projects revealed that the preventive safety activity resources actually invested by contractors are on average only half of the optimal amount [ 33 ]. The issue of insufficient safety investment may undermine the safety performance of practical construction projects.…”

The construction industry suffers from poor safety performance caused by the joint effect of insufficient safety investment by contractors and inefficient safety supervision by the government because of the information gap between the two sides. The present study aims to put forward a new pathway to improve safety investment supervision efficiency and analyze the decision-making interactions of stakeholders under this new pathway. For this purpose, this study establishes a safety investment information system to eliminate the information gap between the government and contractors for construction projects in China and further develops a dynamic safety investment supervision mechanism based on this. Evolutionary game theory is used to describe the decision-making interactions among stakeholders under the current static supervision mechanism and the dynamic supervision mechanism proposed in this research. Moreover, system dynamics is adopted to simulate the evolutionary game process and analyze the supervision effect and equilibrium state of different supervision mechanisms. The results reveal that the proposed safety investment information system could facilitate the transition of the supervision mode from static to dynamic; the evolutionarily stable strategy does not exist in the current static penalty scenario; and the dynamic supervision mechanism that correlates penalties with contractors’ unlawful behavior probability can restrain the fluctuation of the evolutionary game model effectively and the players’ strategy choices gradually stabilize in the equilibrium state. The results validate the effectiveness of the proposed dynamic supervision mechanism in improving supervision efficiency. This study not only contributes to the literature on safety supervision policy-making but also helps to improve supervision efficiency in practice.
