Today, I want to discuss the application of BIM throughout the entire lifecycle of buildings. Among all phases, the operation and maintenance stage of equipment and facilities lasts the longest and incurs the highest costs. Despite its importance, the data available for use during this phase is often limited. In traditional workflows, valuable data from the design and construction phases—such as multiple design changes made during construction—is frequently lost or poorly managed by the time the operation and maintenance phase begins. This results in significant challenges when maintaining and operating the building. The emergence of BIM effectively addresses these issues.
BIM is specifically designed to facilitate seamless information transfer across all stages of a building’s lifecycle. It stores all data related to a building’s equipment in a unified format, including spatial information, materials, quantities, and more. Thanks to this standardized data format, any design changes made during construction are promptly updated in the BIM file, even if BIM was already used during the design phase. As a result, during the maintenance phase, the most comprehensive and detailed building data is readily available.
Traditional facility and equipment management systems typically present data as problem lists or textual reports. However, these text-based formats have limitations, especially when it comes to visualizing the spatial relationships between individual devices. In contrast, a BIM model offers detailed spatial information not only for the entire building but also for the equipment within it. BIM represents a building model that combines physical characteristics with functional facility data.
For BIM to be effective, it must provide a shared knowledge and information resource with accurate data during the design of building facilities. This enables early-stage management of the entire building lifecycle. A key prerequisite for BIM is the involvement of different stakeholders at every stage of the building process. Design updates and construction modifications to equipment and facilities at each stage can be captured in the BIM model, reflecting the interconnected relationships between industry participants. Essentially, BIM serves as a shared information platform with open, interoperable interfaces.
International BIM standards have driven industry demand and facilitated the use of BIM applications throughout every phase of a building’s lifecycle. While this article focuses on the overall application of BIM, it does not delve into detailed BIM applications at each stage—there are many resources available on this topic, especially in China. If you are interested, I recommend reaching out to Du Niang for more information. I hope this article proves helpful to everyone.
