With the rapid advancement and widespread adoption of BIM technology in China’s construction industry, its value is primarily demonstrated in the following areas:
1) BIM-Based Engineering Design
Firstly, BIM enables three-dimensional design, allowing automatic generation of various graphics and documents directly linked to the 3D model’s logic. When the model is updated, all associated graphics and documents are automatically refreshed.
Secondly, BIM facilitates information sharing across different professional disciplines. Each specialized CAD system can access necessary design parameters and related data from the information model, reducing duplication, redundancy, ambiguity, and errors.
Thirdly, BIM supports collaborative design among various disciplines. When an element designed by one profession is modified, related elements in other professional designs are updated accordingly.
Finally, BIM enables virtual and intelligent design processes, including clash detection, energy consumption analysis, and cost forecasting.
2) BIM-Based Construction and Management
Firstly, BIM supports Integrated Project Delivery (IPD) management by bringing together key project stakeholders during the design phase. This approach focuses on the entire project lifecycle and leverages BIM technology for virtual design, construction, maintenance, and management.
Secondly, BIM provides dynamic, integrated, and visual 4D construction management. It links 3D building models with construction progress, integrating construction resources and site layout information to form a comprehensive 4D construction information model. This enables real-time management of project progress, workforce, materials, equipment, costs, and site layout, along with visual simulation of the construction process.
Thirdly, BIM promotes collaboration among all project participants by facilitating information sharing through networked platforms. This supports document submission, review, approval, and use of drawings and videos. Network-based collaboration enables engineering negotiations and coordination for effective multi-party management.
Lastly, BIM enables virtual construction by simulating the construction process on a computer. This helps predict potential issues related to functionality and constructability before actual construction begins, including testing construction methods, simulating processes, and optimizing construction plans.
3) BIM-Based Building Operation and Maintenance Management
Firstly, BIM integrates GIS technology and links with maintenance management plans to provide intelligent, visual management that combines property management with real-time monitoring of building equipment.
Secondly, BIM allows for energy consumption analysis and energy-saving control during the building’s operational phase.
Lastly, BIM supports safety and durability analysis by assessing environmental impacts and disaster damage during operation, predicting structural integrity issues related to material degradation, structural damage, and disaster effects.
