What I want to say about BIM is that BIM Technology supports distributed team collaboration throughout the entire construction project’s whole life cycle. It enables staff, equipment, and workflows to share information more effectively, thereby eliminating data redundancy, duplicate entries, loss, or errors caused by poor communication and misunderstandings.
In the United States, BIM standards provide a clear explanation of BIM. Let me highlight two key points here: it is a shared knowledge resource; throughout different stages of a construction project, each participant embeds, extracts, updates, and modifies information within the information model to support and reflect their respective responsibilities in collaborative work. Based on this definition, information is the true focus emphasized by BIM. Therefore, a 3D model alone, without sufficient or accurate building information, cannot fulfill BIM’s functional role and should not be classified as BIM.
The concept of Building Information Modeling (BIM) originated from 3D models and has evolved into 4D models over time. It stresses that building products should undergo detailed and rigorous product modeling before formal production, similar to manufacturing processes. Just as prototype machines are used for thorough design testing before mass production, buildings require comprehensive design validation. Currently, BIM applications in China appear to be mostly limited to 3D visualization.
In recent years, research on 4D computer-aided design has gained attention in the engineering community. This approach allows project managers to access essential information for decision-making through dynamic 4D visual simulations, improving engineering management efficiency. During project execution, participants must mentally reorganize information such as engineering drawings, work tasks, schedules, and related data to understand the interrelationships of building components across time and space. The goal is to visualize the entire construction process.
Ideally, a single database should store and integrate all building-related data attributes, including geometric shapes of components, material specifications, unit prices, and project schedules — such as planned and actual construction and completion dates for each element. All this information should be recorded in detail within the building information model. A unified data format should be used, encompassing spatial data, materials, quantities, and dimensions. Using such standards, any design changes during construction can be reflected in the model in real time, and the maintenance phase can access the most complete and detailed building information.
Traditionally, data from the design and construction stages often fail to be fully preserved through to the maintenance stage. For example, multiple design changes during construction are usually not properly documented, causing difficulties in maintenance later on. BIM was developed to address the unique challenges of construction projects. Its foundation is to provide a shared knowledge and information resource with accurate data during the building design phase, enabling early management of the building lifecycle.
To summarize, the core premise of BIM is that various stakeholders are involved at each stage of the building lifecycle. Facility design, updates, and construction modifications at every phase are incorporated into the BIM model, reflecting the contributions of industry participants. BIM serves as a shared information platform designed to be open and to support interoperable interfaces. The advancement of international BIM standards has driven industry demand, making such standards essential to BIM’s success.
