The design-assisted BIM business primarily provides construction drawings and related analysis reports for engineering projects. The workflow closely follows traditional architectural design processes. The main advantage of BIM in this context is that it enables designers to increase efficiency, assess design feasibility, and enhance collaboration. Most BIM services offered by architectural design firms fall under this category.
Due to a shortage of BIM professionals, architectural design firms typically establish dedicated BIM teams to maintain project quality. For example, CCDI was one of the earliest organizations in China to research BIM. In 2007, they formed a BIM team, which evolved over time to develop a collaborative workflow between design staff and BIM specialists. This approach not only addresses challenges in design work but also improves overall project quality. Since 2009, CCDI’s BIM team has expanded and, together with computer-aided design and modeling teams, created a new digital building business division.
The design-assisted BIM business can be categorized into three levels based on the BIM team’s expertise and application:
3D Design: Creating models using specialized software and performing clash detection. At this stage, BIM primarily serves as a design coordination tool.
Parameterized Design: Applying parametric methods and technologies to shape the design and support analysis throughout different design phases. This level focuses on ensuring design quality and enhancing accuracy.
Collaborative Design: An integrated design process based on the BIM platform that facilitates information sharing to improve design quality and data connectivity. It also streamlines data conversion for project drawings. This type of BIM business is widely adopted, with firms selecting the appropriate level based on their needs. This approach not only develops talent but also builds valuable BIM experience, helping to advance overall BIM capabilities.
