What is BIM?

BIM refers to building information modeling, which is a comprehensive process of creating and managing information for building assets. BIM integrates structured and interdisciplinary data with intelligent model and cloud platform to generate digital representation of assets from planning and design to construction and operation [1]. Simply put, BIM is a method to manage and realize the whole life cycle of construction projects through digital means. In the process of BIM, architects, engineers, contractors and owners can share the same digital model, so as to achieve more efficient and accurate collaborative work, reduce errors and repetitive work, and improve the quality and efficiency of the project [2].
