4D Modeling and BIM-Based Project Planning Using Constraint-Based Simulation for Implementation in Iran Considering an Actual Case Study

Building information modeling (BIM) allows new levels of spatial visualization, as well as more efficient project management. Despite the advantages of BIM, its proper implementation in projects faces challenges such as the time-consuming and manual process of entering input data and updating models. In countries like Iran, which BIM is not widely implemented, BIM-based project planning, however, will be more difficult than traditional methods like critical path method (CPM), considering the large number of pertinent scheduling parameters. This research focuses on developing a method to create four-dimensional (4D) models with BIM-based scheduling using constraint-based simulation. By using known standard documents and methods in Iran, this framework facilitates the process of creating BIM-based schedules and 4D models in Iran. In this paper, literature related to the research subject will be reviewed, and the modeling method will be explained then capabilities of the proposed will be demonstrated and described through a case study.
