BIM has seen widespread adoption in China, particularly in water supply and drainage projects, where its application has yielded promising results. Traditional design methods often lead to fragmented and distorted 3D data during transmission, causing errors. In contrast, BIM offers a what you see is what you get experience, providing intuitive, real-time capabilities that ensure information remains consistent and intact throughout the process. However, several challenges still exist in applying BIM to water supply and drainage design. Let’s explore these issues in detail.
1. There is currently no unified BIM design standard that fully satisfies the requirements of construction projects.
2. BIM collaborative design operates in two modes: working set mode and linking mode. In working set mode, obtaining and releasing permissions can be cumbersome, while pipeline adjustments during synthesis in linking mode tend to be more complex.
3. BIM aims to cover the entire design workflow—from preliminary budgeting to construction and property management—through extensive parameterization. However, the sheer volume of parameters creates complex hierarchical classifications, which makes modifications difficult and often results in redundant information.
4. The family library remains incomplete and lacks components that comply with Chinese architectural design standards.
5. The functionality for generating 2D drawings is limited and typically requires further refinement.
6. Data exchange remains a challenge, as BIM’s interfaces with various analysis software are not yet fully developed.
7. Before performing pipeline and system calculations, logical and physical connections must be properly established between pipelines and appliances, as well as between pipelines and equipment. If any pipeline is not correctly connected, the entire system calculation cannot proceed.
These challenges highlight that BIM’s application in water supply and drainage design in China still has significant room for improvement. Therefore, localization efforts should be prioritized during BIM implementation. Since BIM design methodologies differ from traditional 2D drawing approaches, widespread adoption may encounter obstacles. It is essential to avoid efficiency losses during the transition to new modeling and design techniques. Despite current limitations in BIM software, ongoing development and digital transformation within the construction industry will drive continuous improvements.
As informatization accelerates, BIM design represents the future direction of the design process. With ongoing adoption and technological advancement, BIM will continue to mature. We believe that widespread acceptance of BIM among water supply and drainage designers is just around the corner.
