Currently, BIM is widely used during the design and construction phases in China. Today, the BIM Architecture Training Network will discuss the benefits of utilizing BIM throughout the construction process.
1. Identifying and Correcting Design Errors Before Construction
In the traditional CAD era, detecting conflicts and clashes between different systems on 2D drawings was extremely challenging. Such issues often only became apparent during construction, leading to costly rework or redesign. BIM models, on the other hand, integrate the designs of various systems into a single model, making conflicts easily visible. This allows for corrections to be made prior to construction, accelerating progress, reducing waste, and significantly minimizing disputes and coordination problems among professionals.
2. 4D Construction Simulation and Optimized Scheduling
BIM technology can connect with 4D software and project schedules to simulate the entire construction process dynamically in 3D. This simulation helps identify potential issues early on and optimize construction plans by addressing site logistics, personnel, equipment, spatial conflicts, and safety concerns. Additionally, 4D simulations incorporate the timing of temporary structures such as cranes, scaffolding, and heavy equipment, supporting cost savings and improving overall scheduling efficiency.
3. BIM as the Foundation for Prefabrication Industrialization
Detailed shop models generated from BIM design models guide prefabrication and construction. Because components are created in 3D, they are well-suited for CNC mechanized production. This automated manufacturing approach has been successfully applied to steel structure processing, metal plate fabrication, and the production of prefabricated components and glass products. It allows suppliers to design and manufacture precise components based on the BIM model, reducing costs and shortening construction timelines. Moreover, it eliminates issues common with 2D drawings, such as components that cannot be installed or require rework due to uncertainties in surrounding elements and site conditions.
4. Enabling Lean Construction
BIM’s parameterized models provide detailed information on the resources required for each task, including personnel, materials, and equipment. This information fosters collaboration between general contractors and subcontractors, enabling just-in-time resource management. By reducing unnecessary inventory, minimizing waiting times, and improving workflow efficiency, BIM supports lean construction practices.
As introduced by the editor of the BIM Architecture Training Network, these are some of the key benefits of applying BIM during the construction phase. Further advantages will continue to emerge as BIM adoption grows and evolves.
