A model for Measuring the Effect of Risk Breakdown Structure on the Purpose of the Construction Projects of Isfahan Municipality by Structural Equations Approach

Today, the proper management of project risk is one of the most important steps of project management in project-oriented organizations. Therefore, the aim of the present study was to identify the effects of different dimensions of risk breakdown structure (RBS) on the goals of on the purpose of Isfahan municipality construction projects. The present descriptive-survey research was a correlation type study. The statistical population of the study was based on purposive sampling in fifteen districts of Isfahan municipality. To write an RBS, the projects were classified based on urban areas and considering the scheduling programs and breakdown structure of municipality projects through interviewing with open and semi-structured questions. To collect data, a questionnaire that its validity and reliability had been confirmed, was used. After verifying the normality of the data, the PLS structural equation modeling technique was used to examine the assumptions at the third level of the RBS of Isfahan municipality’s construction projects for the surface analysis of the hypotheses. The results of this study showed that in the third level, the risk-failure structure of 28 variables has a positive and significant effect as the main hypothesis. There are also 32 positive and significant variables from 131 sub-hypotheses of the research, and the risk of the consultant has a positive and significant effect on the goals of the project. The results also showed that the risk category resulting from the design of the first phase of the projects had the most positive and significant effect on the design of the second phase.
