BIM, or Building Information Modeling, is a digital representation of a building's physical and functional characteristics. It allows architects, engineers, and construction professionals to create and manage a project in a collaborative environment. By using 3D models, teams can visualize the design, identify potential issues, and improve communication throughout the project lifecycle. The use of BIM enhances efficiency and accuracy in construction projects. It enables better planning, reduces errors, and helps in cost estimation. Additionally, BIM supports facility management by providing valuable data for maintenance and operations after the building is completed.
