Many people say that BIM is widely used during the construction phase in China. But what exactly is the value of BIM at this stage? Why is it essential to use BIM? Today, the editor of the BIM Architecture Training Network will offer a brief, personal perspective to shed some light on these questions.
1) Enabling seamless data transfer between project stages
BIM models play a crucial role in bridging different stages of the construction process. For example, from design to construction, the upstream design model serves as the foundation for the construction model. Through detailed design development, the construction model can be refined to effectively guide the building process. Similarly, from construction to operation and maintenance, the continuously updated BIM models and related data collected during construction can provide invaluable support for facility management.
2) Facilitating communication and enabling quick decision-making
The 3D visualization capabilities of BIM models are a powerful tool not only during the design phase—helping project leaders evaluate design options—but also throughout construction. For instance, when changes arise on site, BIM makes it easy to visually compare the original and revised plans. It can even directly present quantity and cost variations, empowering decision-makers to respond swiftly and confidently.
3) Using simulation analysis to guide construction
Complex construction details can be simulated in 3D before actual work begins. This includes process simulations and component layout checks, such as verifying steel rebar placement to avoid clashes. Additionally, 3D simulations of temporary works like formwork and scaffolding help optimize material cutting, inspect workspaces, and improve arrangement efficiency, thereby minimizing rental waste.
4) Off-site processing to boost productivity
Off-site processing involves shifting from a traditional “Design → On-site Construction” model to a “Design → Factory Manufacturing → On-site Installation” approach. This strategy addresses issues such as limited site space, reduces labor costs, improves manufacturing precision, and enhances overall labor productivity.
5) Delivering operation and maintenance information
During construction, a wealth of information is embedded into the BIM model, including material supplier details and equipment manuals. Upon project completion, both the physical building and its virtual BIM model can be handed over to the owner. This allows building occupants to access detailed information about any device or system simply by viewing the 3D virtual model on a computer or tablet. This seamless integration between BIM and Facility Management (FM) is a key advantage.
6) Promoting networked and mobile BIM applications
Thanks to advances in network technology and the proliferation of mobile devices, BIM applications increasingly rely on cloud platforms and mobile terminals. Imagine this: while others are still distributing construction change plans on USB drives, you can instantly download the latest documents from the project platform via the internet. Or instead of carrying stacks of drawings to the site, you quickly search and find the relevant construction section on your lightweight iPad for immediate reference. This shift represents significant progress in construction management.
The above points summarize my personal insights on the value of BIM during the construction phase, based on real-world projects. I hope this overview proves helpful to everyone.
