Building Information Modeling (BIM) is a process for creating and managing information on a construction project across the project lifecycle. It involves creating a virtual 3D model of a building that contains both geometric and nongraphic data. Key benefits of BIM include improved design coordination, reduced construction conflicts and waste, more accurate cost estimation, and better project outcomes. BIM involves integrating parametric object-oriented building components within a 3D model and sharing this information collaboratively between stakeholders in a digital format. It allows for clash detection and simulations to optimize construction planning and operations.
