Abstract
This paper studies the factors affecting the progress of engineering projects under the EPC model. By establishing a hierarchical comparison matrix and collecting respondents’ ratings on the importance of these factors through a questionnaire survey, the data was analyzed and summarised using the Analytic Hierarchy Process (AHP). The study identified the key factors influencing progress management by the general contractor in EPC projects. Project participants can focus their efforts and resources on managing these key factors to more effectively manage construction progress, shorten project duration, improve management efficiency, and reduce social burdens and resource waste.
