Due to its hazardous nature, occupational injuries are unavoidable in the construction industry. Although many precautions are taken and educations are given to the laborers and employers, zero occupational injury rate could not be achieved, but a decrease in the number of injuries and fatalities could be maintained. The conventional studies conducted so far, usually focused on the prevention and causation models. The approach of the researchers was, either proactive or reactive about the accidents which offered preventive or protective precautions. However, after the occurrence of an injury, these precautions become useless and from this point on, determination of the fault rates for the parties being involved in that injury becomes the critical issue. Mostly, it is difficult to reach an objective and correct conclusion at the phase of determining fault rates and decisions achieved may display great fluctuations from one expert to another. The aim of this study is to develop an expert system that reflects the knowledge of occupational safety experts for the determination of fault rates. In order to facilitate this research, required data were collected from related organizations and experts. These data were compiled and classified, the significant factors were determined and all of these factors were evaluated within a quantitative approach. In addition to this evaluation, questionnaires were submitted to the experts; at which they were asked to rate the factors which were determined by the researcher of this study. The expert system is based on these ratings and factors obtained from questionnaires.
