Data mining of the essential causes of different types of fatal construction accidents

Accident analysis is used to discover the causes of workplace injuries and devise methods for preventing them in the future. There has been little discussion in the previous studies of the specific elements contributing to deadly construction accidents. In contrast to previous studies, this study focuses on the causes of fatal construction accidents based on management factors, unsafe site conditions, and workers' unsafe actions. The association rule mining technique identifies the hidden patterns or knowledge between the root causes of fatal construction accidents, and one hundred meaningful association rules were extracted from the two hundred and fifty-three rules generated. It was discovered that many fatal construction accidents were caused by management factors, unsafe site circumstances, and risky worker behaviors. These analyses can be used to demonstrate plausible cause-and-effect correlations, assisting in building a safer working environment in the construction sector. The study findings can be used more efficiently to design effective inspection procedures and occupational safety initiatives. Finally, the proposed method should be tested in a broader range of construction situations and scenarios to ensure that it is as accurate as possible

BIM benefits and its influence on the BIM implementation in Malaysia

Building Information Modelling (BIM) implementation is considered a daunting reality because majority of the construction players don’t know the potential benefits of the technology. Awareness of BIM benefits and its implementation could significantly increase project productivity and performance. This study is aimed to determine the influence of BIM benefits from the Malaysian construction stakeholders’ perception towards its implementation. The study was carried out using survey questionnaire. Out of 590 questionnaires 268 were collected that represent a sample size of 346. Results revealed that most of the construction companies lack of awareness about BIM technology. The statistical analysis showed that productivity, time, cost, clashes, and communication are the most essential BIM benefits that concerned the participants. The driving factors of implementation, on the other hand, were identified as Trust, respect, commitment, early involvement, and knowledge. It is also found that there is a significant relationship between BIM benefits and its implementation

Mechanism Models of the Conventional and Advanced Methods of Construction Safety Training. Is the Traditional Method of Safety Training Sufficient?

Cognitive failures at the information acquiring (safety training), comprehension, or application stages led to near-miss or accidents on-site. The previous studies rarely considered the cognitive processes of two different kinds of construction safety training. Cognitive processes are a series of chemical and electrical brain impulses that allow you to perceive your surroundings and acquire knowledge. Additionally, their attention was more inclined toward the worker’s behavior during hazard identification on-site while on duty. A study is proposed to fill the knowledge gap by developing the mechanism models of the two safety training approaches. The mechanism models were developed based on cognitive psychology and Bloom’s taxonomy and six steps of cognitive learning theory. A worker’s safety training is vital in acquiring, storing, retrieving, and utilizing the appropriate information for hazard identification on-site. It is assumed that those trained by advanced techniques may quickly identify and avoid hazards on construction sites because of the fundamental nature of the training, and when they come across threats, they may promptly use their working memory and prevent them, especially for more complex projects. The main benefit of making such a model, from a cognitive point of view, is that it can help us learn more about the mental processes of two different types of construction safety training, and it can also help us come up with specific management suggestions to make up for the approaches’ flaws. Future research will concentrate on the organizational aspects and other cognitive failures that could lead to accidents
