In recent years, there is a growing interest in using the design-build delivery system and EPC contracts in the country's construction industry. In this delivery system, performing the design and execution phase by a single organization helps the integration of different phases of the project. In design-build delivery system, due to the overlap of different phases of the project, this integration is more important and the need for proper management becomes more urgent. The experience of the project parties shows that this delivery system in Iran has not fully achieved its desired interests and not managed in the integration different phases, due to lack of understanding of this field and its issues. This research tries to understand the factors affecting the integration due to the high importance of design and execution phases in EPC projects in the country's construction industry, helping to better understand this field and to suggest solutions. This research is a quantitative-qualitative research and in terms of data collection method, is a descriptive-analytical research. For this purpose, after reviewing the background, In the first stage, statistical analysis methods were used to analyze the raw data obtained from the questionnaires, and thus screening the identified factors was determined. In the next step, the Analytic Hierarchy Process (AHP) method and Expert choice software was used to prioritize the factors. Analysis of the data showed that the 10 factors were identified as the most important factors in the integration of design and execution of EPC projects in the construction industry and were prioritized.
