Factors influencing safety performance on construction projects: A review

Construction is one of the most dangerous industries due to its unique, dynamic, and temporary nature. This paper aims to review and extract the factors influencing safety performance on construction projects. In the presented work, methodologies, results, discussions and findings from a total of 90 previous papers are investigated to achieve the paper objectives. The reviewed papers are categorized based on their type, methods of data collection, analytical method, research objectives, key findings and contributions, limitations, year, and the country of origin. A qualitative content analysis procedure is used to extract variables and factors. Furthermore, a hierarchical framework is developed to illustrate how the extracted factors influence safety on construction projects. The proposed framework is validated by using interviews with experts. The hierarchical framework explicitly confirms that safety performance not only is determined by management activities within project levels, but also by the interactions among factors at different hierarchical levels.
