Slowness and lack of progress in the implementation of construction projects that lead to the lack of sustainable urban management suggest that there are obstacles and problems in implementing valuable urban projects that threatens the rehabilitation and development of urban space in a manner that can be described as the crisis of construction projects. The major problem that most of the major construction projects will face is the delay in various phases and the completion of the project. Therefore, information management and processing of data is very important in predicting the process of developing construction projects using information data as a result of supporting policy making and right decisions for managers. in this article, the use of the decision-making method of CPM to support decision making in the project management of the construction of non-level intersection of Hossein-Abad (project of opening the northern axis of Valiasr Boulevard with Tehran-Tabriz railway) has been discussed in this study.
In processing, MSP software to implement the construction project information has been used with the knowledge of choosing the CPM method, which resulted in determining the project's time, resources required, and the cost of doing the work. In this study, the problems and resources needed for the project before the implementation phase were determined and its critical points were determined with the help of the decision-making system.
