BIM is a process that generates and manages building data throughout its lifecycle using 3D modeling software. BIM can incorporate up to 8 dimensions including 3D visualization, 4D scheduling, 5D cost estimation, 6D facilities management, 7D sustainability analysis, and 8D safety planning. Key advantages of BIM include increased productivity in design and construction through real-time collaboration and dynamic modeling. Proper implementation of BIM requires defining the level of detail at different project stages.
