Recently, I have received numerous questions from friends who are new to the BIM industry, many of which relate to BIM Technology. Although I have previously written extensively on this topic and prefer not to repeat myself, I would like to share my own introduction to BIM here, avoiding overly conceptual explanations.
Since the development of object-oriented theory and technology in information technology during the 1960s, the academic communities in Europe and America began applying object-oriented techniques to describe product lifecycle information. This approach facilitated information exchange and transmission across various stages such as creation, organization, usage, and maintenance. In recent years, product information models have matured significantly, becoming widely adopted and incorporated into international standards. This laid the foundation for describing building lifecycle information models both theoretically and practically.
In the 1980s, Charles Eastman from the Georgia Institute of Technology published Building Product Models, which offered a comprehensive introduction to organizational principles, information modeling concepts, ISO-STEP, Industry Foundation Classes (IFC), and other aspects of building component information modeling. This work broadened the concept of the Building Information Model. Later, Phil Bernstein, Vice President of Autodesk, popularized the term Building Information Modeling to describe the functional design philosophy behind ACE-related products. Additionally, construction industry analyst Jerry Laiseling proposed a standardized information exchange format. This led to the adoption of BIM concepts and technologies by three major drafting software companies—Autodesk, Bentley Systems, and Graphisoft—enabling information exchange and interoperability between software tools.
BIM refers to the technology of digitizing information and applying tools throughout the lifecycle of construction engineering facilities to establish and maintain building products. In essence, it uses computer simulation to assist with management and engineering operations at various stages, including planning, design, construction, operation, and maintenance. Broadly speaking, BIM can describe a digital 3D model of a building, encompassing a structured dataset of form and meaning, known as the Building Information Model. It also represents the process of creating such a model—sometimes called building information modeling—or a system for managing this data. Introducing BIM into the construction industry is akin to implementing a new business system model, often referred to as building information management.
Large-scale construction projects involve diverse professions with detailed divisions of labor. This complexity often results in numerous interfaces, poor communication, fragmented information, or incomplete data transmission. By applying BIM concepts and technologies for visualization, information transfer, and sharing, the quality of public works can improve significantly. BIM helps reduce costs caused by errors and changes, shortens construction timelines, promotes cross-disciplinary integration, and enhances communication management across various interfaces.
This has been my introduction to BIM, and I hope it provides a clear overview. In truth, I prefer not to dwell excessively on conceptual explanations, as there are already many introductions to BIM available online and through other media. If someone were to ask me, What is BIM? this is how I would explain it.
