“…However, obtaining data on construction accidents is nearly impossible as the records are simply unavailable. Where the records are available, they hardly establish the basic causes of the accidents being investigated [6,9,12,30,31]. Thus, the accident investigation records are mostly incomplete and inaccurate in serving as a safety hazard source and the predominant project site conditions that cause them.…”

“…In the last decade, there have been over a thousand reported cases of crane accidents worldwide [8]. As Song [9] pointed out, working with tower cranes to lift loads during construction is among the major causes of accidents and loss of lives in the construction industry. For instance, in 2015, a tower crane collapsed onto the Grand Mosque in Makkah, Saudi Arabia, killing over one hundred persons.…”

Considering a large number of Small and Medium-Scale Contractors (SMSCs) dominating the construction industries of many developing nations and the increasingly high rate of tower crane accidents in the industry, this paper seeks to methodically determine the safety risk factors that are significant in influencing construction site safety, especially on sites where the SMSCs operate tower cranes. The paper will further assess the extent to which each safety risk factor affects safety on construction sites. Data for the study was obtained through a literature search, site visual observations, discussions with site operators, and structured questioning of safety and equipment managers of leading construction companies. The study's findings reveal that the operator's low experience level was the most significant factor influencing construction site safety, particularly when operating tower cranes. This paper systematically investigates the key safety risk factors that influence construction site safety when operating tower cranes. The paper presents a clear methodology for identifying and prioritizing the safety risk factors, which may readily apply to other construction equipment. The findings of this paper are expected to play an important role in promoting and enhancing a safety culture for operating tower cranes in construction sites, particularly the project sites operated by the SMSCs.

The unsafe behavior of miners seriously affects the safety of deep mining. A comprehensive evaluation of miners’ unsafe behavior in deep coal mines can prevent coal mine accidents. This study combines HFACS-CM, SEM, and SD models to evaluate miners’ unsafe behaviors in deep coal mining. First, the HFACS-CM model identifies the risk factors affecting miners’ unsafe behavior in deep coal mines. Second, SEM was used to analyze the interaction between risk factors and miners’ unsafe behavior. Finally, the SD model was used to simulate the sensitivity of each risk factor to miners’ unsafe behavior to explore the best prevention and control strategies for unsafe behavior. The results showed that (1) environmental factors, organizational influence, unsafe supervision, and unsafe state of miners are the four main risk factors affecting the unsafe behavior of miners in deep coal mines. Among them, the unsafe state of miners is the most critical risk factor. (2) Environmental factors, organizational influence, unsafe supervision, and the unsafe state of miners have both direct and indirect impacts on unsafe behaviors, and their immediate effects are far more significant than their indirect influence. (3) Environmental factors, organizational influence, and unsafe supervision positively impact miners’ unsafe behavior through the mediating effect of miners’ unsafe states. (4) Mental state, physiological state, business abilities, resource management, and organizational climate were the top five risk factors affecting miners’ unsafe behaviors. Taking measures to improve the adverse environmental factors, strengthening the organization’s supervision and management, and improving the unsafe state of miners can effectively reduce the risk of miners’ unsafe behavior in deep coal mines. This study provides a new idea and method for preventing and controlling the unsafe behavior of miners in deep coal mines.

“…Moreover, as these models only study the causes of construction safety accidents from the perspective of objective influencing factors, they neglect the construction process main body, namely the behavior influencing construction safety accidents. Especially in PB projects, the supervision of governmental personnel and the attitude of construction personnel play an important role in construction safety accidents (Song et al, 2022). SD is a tool for analyzing and studying information feedback systems and is a cross-cutting, comprehensive method that explores how to understand and solve system problems (Li et al, 2017).…”

PurposeThis study aims to reduce the construction safety accidents of prefabricated building (PB) projects, improve the efficiency and effectiveness of safety supervision by government departments, and provide theoretical reference for improving the safety supervision system of PB construction.Design/methodology/approachConsidering the information asymmetry between government supervision departments and construction contractors and the interactive relationship between the two parties under bounded rationality, we propose an evolutionary game model for the construction safety dynamic supervision of PBs and analyze the evolutionary strategy of the game. The system dynamics (SD) method is used to simulate and analyze the evolutionary game process under a dynamic supervision strategy and the adjustment of external variables.FindingsThe cost difference between the government's strong and weak supervision, the construction contractor's additional expenditure for strengthening safety management, and other factors affect system stability. The government can dynamically adjust the penalties based on the construction contractor's subjective willingness to ignore safety management and further adjust their rate of change based on the completion of the supervision goals to improve the efficiency and effectiveness of construction safety supervision.Originality/valueThis study makes contributions in two areas. Through a combination of SD and an evolutionary game, it provides new insights into the strategic choice of the main body related to PB construction safety. Additionally, considering the nonlinear characteristics of construction safety supervision, it provides useful universal suggestions for PB construction safety.
