If the three elements serve as the foundation for Chinese design firms to implement BIM, and enterprise-level BIM implementation standards systematically cover these elements, then what are the typical breakthrough points within enterprise BIM standards that deserve attention?
When examining the practical BIM application environment in Chinese design enterprises, the focus should be on the processes and the internal deliverables associated with each stage as key breakthrough points.
When developing a BIM implementation plan for an enterprise, it is crucial for the planners to understand that the emphasis of the BIM design approach lies not in the final results or tools, but in the process and the business model innovation driven by changes in deliverables. Within the BIM design framework, the division of design stages and the internal deliverables produced at each stage will shift. Accordingly, the evaluation system must adapt to these stage divisions and the changing workload involved in each phase. For instance, under the BIM design model, the fee proportion allocated to the schematic design phase should be significantly increased.
Enterprise managers should not mandate the use of specific BIM tools by designers; instead, they should guide and enforce requirements based on deliverables. For example, for projects governed by BIM implementation standards, proposal submissions cannot be limited to floor plans plus renderings. Instead, BIM models along with their related design documents—such as plans, elevations, and sections—must be submitted. While BIM models may be incomplete or unavailable at times, the plans, elevations, and sections describing the proposal must be consistent and interconnected. Using traditional design workflows—where design documents are drawn separately in AutoCAD—would result in a massive workload and create difficulties in managing changes. Therefore, BIM becomes the only practical solution.
Because BIM models affect the deliverables and value at each stage differently, a significant portion of design effort occurs early in the process, which must be reflected in resource allocation. One of the most notable shifts is the fundamental change in the fee percentages assigned to schematic designs versus construction drawings.
Regardless of whether the project owner requests it, submitted drawings for review must include completed clash detection and a relatively comprehensive integrated pipeline diagram. When designed using BIM, this does not add extra workload; however, without BIM, it generates considerable additional effort.
