increasing safety in construction methods using failure modes and effects analysis (fmea) in tehran's towers

the construction industry is a fundamental industrial asset of national construction, which plays an important role in the economic development of developing and developed countries. because there is a lot of compaction and complexity in the field of work in this industry. damage in this industry leads to death, serious occupational injuries and lost time due to its unique nature. fmea is a structured way to begin designing or reviewing and developing a product or process plan in an organization. this method can be used to link many key organizational issues and their specific documentation. the purpose of this study is to provide a method for assessing the safety risks of construction projects using the fmea method, to help them to investigate the root and real risks and causes of their occurrence, and provide appropriate solutions to reduce these risks. according to the results of the comparison, the rpn index for various variables affecting safety has been observed in the building projects. in sum, the most significant variables including the lack of workers' consciousness with a probability of 24.9%, poor planning with a potential of 23.7%, were exposed the unsafe situation was identified with a 22.2% probability and a lack of coordination among members with a probability of 22.2%. also, based on the comparison of the rpn coefficient for the main safety indicators in the building projects, it has been observed that the impact on the safety of tehran's building projects has been due to personal factors. second-order adverse conditions are also important. insecure acts in this category have had the least impact.
