“…Especially, the superintendent effect has "superintendent character" and "site-level safety management" to influence the safety of the crane-related site, a total of over 23%. In other previous study [20], as a result of analyzing the previous literature, the causal factors belonging to "site personnel management" are also very important as the frequency occupies the first to third place. In this study, most accident causes are related to situation/surrounding control using T/Cs and management issues that require workers to comply with work guidelines and rules of erection, dismantling, and lifting works that reflect reality.…”

“…Since the 2000s, various studies related to T/C accidents have been conducted around the world. These studies can be classified into three major categories: (1) risk analysis for analyzing T/C accidents [13,14], (2) development of management goals or plans by analyzing T/C accidents [14][15][16], (3) derivation of the major accident causes related to T/C accidents [17][18][19][20][21], and (4) presenting measures for preventing tower crane accidents [22]. Thus far, most studies have focused on the causes or risks of T/C accidents based on specific causes and direct management.…”

“…Thus far, most studies have focused on the causes or risks of T/C accidents based on specific causes and direct management. Especially, Fang et al [22] developed a framework for real-time pro-active safety assistance (RPSA) for mobile crane lifting operation, and Zhang et al [20] and Zhou et al [21] presented the tower-crane accident cause system (TCACS) model, which was a quite logical model through system thinking and case analysis to quantify the tower crane accident causes. However, there was a limit to revealing the direct cause of T/C accidents.…”

Construction safety is a key factor among the many factors related to the sustainable management of construction sites. Although research is underway to reduce potential accidents in the construction industry in Korea, the number of tower crane (T/C) accidents is consistently increasing based on the increased use of such cranes. In this study, the priorities of accident causes for each T/C type were derived and utilized for the sustainable management of construction sites. An analytic hierarchy process (AHP) questionnaire was completed by experts such as construction engineers, construction managers, safety engineers, and T/C operators with more than ten years of field experience. The results of the AHP questionnaire revealed that the leading cause of cab-control T/C accidents is poor operator visibility, while the leading cause of accidents related to remote-control T/Cs is the poor management of lifting objects and control of surroundings. The high-ranking causes derived in this study should be managed and priority measures should be implemented to reduce the number of T/C accidents.

“…The collected data was analyzed by a multi-criteria decision-making method, fuzzy DEMATEL. DEMATEL was selected particularly for its wide application as a practical method to underly root causes of various problems in the literature [52] such as labor productivity [53], intersection safety [54], waste management [55], and project performance [56]. This method has been used by many researchers, since it is powerful in separating net causes from net effects ensuring the underlying causes of the problems [54], drawing a root cause degree (RCD) diagram and aiding the development of countermeasures to the specific issues [57].…”

Issues related to readability risks in contracts could exacerbate conflict, claim and dispute occurrences in construction projects. Determination of root causes of readability risks by defining casual relationships in construction contracts is essential to improve contract documentation and enable successful risk management. This paper aims to differentiate net causes from net effect factors of readability risks in construction contracts. Most significant readability risks in construction contracts were analyzed using fuzzy decision-making trial and evaluation laboratory (DEMATEL) method, which is known for its wide implementation in similar problems. Root cause degree (RCD) diagram was drawn to illustrate the differentiation of these factors by adopting maximum mean de-entropy (MMDE) algorithm. Analysis results indicated that poor grammar use, legal terminology, visual representation, and negative language were the major underlying cause factors; while lengthy document, use of abbreviations, scope complexity, controversial uses, repetitions, and ambiguous words were the net effect factors. The results are expected to improve readability of contract documents, which would contribute to more effective risk management and better allocation of project resources.

“…Research evidence has shown that human unsafe behavior is the most important reason affecting construction safety production ( Park et al, 2020 ; Zhang et al, 2020 ). Among the accidents on construction sites, 90% are caused by human errors ( Newaz et al, 2020 ), and 88% of construction engineering accidents involve human unsafe behavior ( Suraji et al, 2001 ).…”

At present, China’s engineering safety management has developed to a certain level, but the number of casualties caused by construction accidents is still increasing in recent years, and the safety problems in the construction industry are still worrying. For purpose of effectively reducing construction workers’ unsafe behavior and improve the efficiency of construction safety management, based on multi-agent modeling, this paper analyzes the influencing factors during construction workers’ cognitive process from the perspective of safety cognition, constructs the interaction and cognition of the agent under the bidirectional effect of formal rule awareness and conformity mentality model, and set behavior rules and parameters through the Net Logo platform for simulation. The results show that: Unsafe behavior of construction workers is related to the failure of cognitive process, and the role of workers’ psychology and consciousness will affect the cognitive process; The higher the level of conformity intention of construction workers, the easier it is to increase the unsafe behavior of the group; Formal rule awareness can play a greater role only when the management standard is at a high level, and can correct the workers’ safety cognition and effectively correct the workers’ unsafe behavior; Under certain construction site environmental risks, the interaction between formal rule awareness and conformity mentality in an appropriate range is conducive to the realization of construction project life cycle management. This study has certain theoretical and practical significance for in-depth understanding of safety cognition and reducing unsafe behavior of construction team.
