Building Information Modeling (BIM) is a digital representation of the physical and functional characteristics of a building. It allows architects, engineers, and construction professionals to create and manage a 3D model that contains detailed information about the structure, including materials, dimensions, and systems. This collaborative approach enhances communication and coordination among project stakeholders. BIM improves project efficiency by enabling better planning, visualization, and analysis throughout the building's lifecycle. It helps identify potential issues early in the design process, reducing costly changes during construction. Overall, BIM supports informed decision-making and promotes sustainable building practices.
