Building Information Modeling (BIM) is a digital representation of a building's physical and functional characteristics. It allows architects, engineers, and construction professionals to create and manage a 3D model that includes detailed information about materials, dimensions, and systems. This collaborative approach enhances communication and coordination among all stakeholders involved in a construction project. BIM improves project efficiency by enabling better planning, visualization, and analysis. It helps identify potential issues early in the design process, reducing costly changes during construction. By integrating data throughout the building's lifecycle, BIM supports maintenance and operations, making it a valuable tool for facility management.
