How does BIM facilitate data sharing and coordinated management? The use of BIM technology enhances the accuracy of construction budgets, supports prefabrication processes, and significantly improves the precision of equipment specifications and construction coordination. By fully leveraging the BIM sharing platform, true information exchange and efficient management can be achieved.
First, BIM models are parameterized, which leads to improved budget accuracy. During the modeling process, various construction components are assigned constraint parameters such as size, type, and material. Since BIM is developed through repeated verification and adjustment within a visualized design environment, the material and equipment data generated from it is highly reliable. This data can be directly integrated into project budgets, providing a solid foundation for cost control and construction settlement.
Traditionally, construction settlements relied on manual measurements and drawings. Today, BIM models allow for automated data generation, greatly increasing the accuracy of budgeting and settlements. Many construction units prefabricate components like doors, windows, steel structures, and mechanical and electrical pipelines in factories before installation on-site. Using BIM data reduces the need for on-site surveys of prefabricated structures, while improving the accuracy and speed of component fabrication. This shifts construction from a fragmented, labor-intensive process to an integrated, modular approach on site. It effectively addresses challenges such as limited on-site workspace, difficult vertical transportation, and quality control issues, thereby boosting efficiency and lowering costs.
In the past, prefabrication depended on on-site surveying, which often resulted in inaccuracies. Prefabricating based on validated BIM models and generating fabrication drawings through software—with logistics numbering assigned to each pipe section for factory processing—provides a reliable solution.
Second, BIM enhances the precision of equipment parameter verification. During mechanical and electrical installations, the design of pipelines is carefully balanced, but adjustments during finishing work can alter pipeline routes, affecting system reviews. By using accurate BIM model data to perform system calculations, more precise data becomes available, offering a solid basis for selecting equipment parameters.
Third, BIM simplifies construction coordination and management. Through data sharing, 4D construction simulations, and remote monitoring, BIM creates an information exchange platform among all project participants. For complex projects like the Shanghai Center—characterized by intricate structures, extensive systems, and multiple functions—effective coordination among construction units is critical. Using BIM as a shared information platform enables owners, design firms, consultants, general contractors, specialty subcontractors, material suppliers, and others to access and share data seamlessly. This improves communication, strengthens collaboration, and enhances overall management efficiency.
In summary, BIM represents a revolutionary advancement for future construction enterprises, fundamentally transforming how projects are designed, coordinated, and executed.
