When discussing BIM, it is commonly understood as a Building Information Model that transforms 2D CAD drawings into 3D visual representations. While this reflects the BIM model, this interpretation is actually incomplete.
Throughout the entire project lifecycle, BIM models are not static; rather, they are dynamically generated. The correct conceptual understanding of BIM models is that they continuously evolve by integrating information from all project phases. These models are intended to be accessible and useful to all stakeholders involved in the construction process.
From an application perspective, as illustrated in the figure, the BIM model is created dynamically at each project stage. Each phase produces its own version of the model, incorporating relevant information and serving the specific needs of that stage. These different versions enable data exchange and sharing through standardized platforms, facilitating collaboration among all parties.
Due to varying responsibilities across different roles, distinct models are generated and utilized at each project phase. The design model initiates this process. During the bidding stage, modifications and additions are made to the design model to develop a computational model. Similarly, in the construction phase, further changes based on both the design and computational models lead to the creation of the construction model. Ultimately, this evolves into the model used for the operation and maintenance phase.
This highlights that BIM models are more than just data collection tools; they must encompass multiple project stages to remain practical and effective throughout the entire project lifecycle.
