In recent years, the promotion and widespread adoption of BIM in the construction industry have significantly boosted productivity. The construction sector is essentially a big data industry. As modern projects grow in scale, considerations now include environmental, cultural, and social factors, making traditional technologies and management methods increasingly inadequate. BIM’s features allow for the integration and analysis of vast amounts of data. By incorporating the concept of a building’s lifecycle, BIM breaks down traditional communication barriers, establishes a unified information analysis platform, and greatly enhances work efficiency.
Traditionally, the construction industry has relied heavily on graphical and textual communication. Errors or omissions in paper documents often lead to increased costs, project delays, and even disputes or litigation. To address these challenges and improve efficiency, the concept and technology of Building Information Modeling (BIM) have gained considerable attention and widespread application in recent years. BIM represents a new approach to managing engineering operations and communication throughout the entire lifecycle of a building project—from planning and design to construction, operation, and maintenance. It leverages 3D visualization tools to facilitate information exchange and integration, overcoming the limitations of traditional 2D drawings and reducing communication gaps across various engineering disciplines.
BIM is essentially the digitization of information and the application of tools used to create and maintain building facility products throughout the lifecycle of construction projects. In other words, it employs computer simulations to assist in managing various stages such as planning, design, construction, operation, and maintenance. Broadly speaking, BIM can refer to the digital 3D model of a building, which includes a structured dataset representing both form and function—known as the Building Information Model. It can also describe the process of creating this model, often called building information modeling, or the overall system involved. When the construction industry adopts BIM as a new operational model, it can be considered building information management.
Large-scale construction projects involve diverse professions and detailed divisions of labor. This complexity often results in numerous interfaces, communication breakdowns, fragmented information, or insufficient data transmission. By applying BIM concepts and technologies for visualization, information sharing, and communication, the quality of public works can be improved, costly errors reduced, construction time shortened, disciplines integrated, and communication interfaces effectively managed. Due to time constraints, this introduction focuses on the key characteristics of BIM concepts, with the hope of offering valuable insights.
