The application of Building Information Modeling (BIM) in China has been underway for some time. In recent years, with the introduction of various standards and policies by central and local governments, the industry is poised for significant growth. However, many challenges remain. Today, we will discuss these issues and their potential consequences. What are the problems with BIM implementation? What outcomes might they lead to?
1. BIM Goals and Common Implementation Challenges
How can BIM contract content be structured to align with the owner’s objectives and promote effective adoption?
The initial BIM adoption process often limits its scope to basic model visualization, which leads to misunderstandings about the depth and detail required for model components.
Additionally, unclear BIM goals mean that even when contracts require the delivery of a BIM model, there is no standardized definition of what the model should include or how the information should be applied. This leaves owners unable to effectively use the delivered models.
Owners may also arbitrarily add BIM tasks, increasing costs for the executing teams without clear justification.
Consequences: Unclear owner objectives make it difficult to specify information requirements in contracts, causing disputes over deliverables. Misinterpretations of standards by auditors, who use guidelines as acceptance criteria, further complicate matters for BIM teams.
2. Accuracy Issues of BIM Model Components
Many contracts oversimplify Level of Development (LOD) by treating it as a single metric for the entire building model, misunderstanding that different components require different levels of detail depending on their design and construction phase.
There is also a lack of reference standards defining the parameter information required at each stage of the model’s development, resulting in poor information transfer among project participants.
Consequences: The absence of domestic construction information standards means referencing all AIA LOD standards without adaptation can hinder collaboration and waste resources. Lack of precision standards makes it difficult for equipment manufacturers to adopt BIM technology, and chaotic information exchange between designers and contractors limits BIM’s benefits.
3. Responsibility Division and Communication Coordination Challenges
Often, BIM modeling is outsourced to specialized units that do not integrate well with the design teams.
Current general engineering contracts lack provisions regarding the selection, responsibilities, workflows, compensation, and risk management for BIM managers and tools.
During design phases, coordination and data synchronization across architecture, structure, MEP, HVAC, and equipment disciplines remain unstructured, and no collaborative BIM operation model has been established.
Consequences: Without clear responsibility definitions for BIM work at each stage, information exchange becomes confusing. Upstream participants may fail to properly create and maintain BIM data, forcing downstream teams to reconstruct information and reducing BIM’s effectiveness. Insufficient BIM capabilities among contractors also hinder horizontal and vertical coordination.
4. Issues with Deliverables at Each Stage
Contracts often fail to specify which items and documents are payable, as well as the payment methods and required documentation.
Currently, there is no standard for replacing traditional 2D as-built drawings with BIM deliverables suitable for operational management.
Consequences: Ambiguous owner BIM goals and undefined deliverables lead to disputes during contract execution. BIM services are mistakenly treated like simple simulations, causing acceptance fears for owners. Consequently, BIM quality cannot be guaranteed during handover, and manufacturers are reluctant to assist with model corrections post-acceptance, reducing the model’s overall value.
5. BIM Intellectual Property Rights Concerns
Issues arise regarding third-party liability for damages caused by errors in architects’ BIM models.
There is no consensus on how existing copyright laws protect BIM data, especially concerning potential contractual disputes over shared responsibilities and localized data management.
Consequences: Incomplete intellectual property regulations discourage participants from sharing BIM contributions, limiting collaborative benefits. Misunderstandings about rights and responsibilities can lead to contractual conflicts.
6. BIM Service Fee Challenges
Currently, BIM design budgets are inadequate to cover modeling requirements.
Consequences: Existing procurement contracts fail to reflect BIM’s value, preventing designers from receiving fair compensation for additional labor. This reduces willingness to cooperate on BIM tasks. Contractors then must duplicate modeling efforts, diminishing BIM’s overall efficiency.
In summary, despite progress through policies and regulations, many challenges remain in BIM application across China. No unified or mandatory standards have been established, indicating a long road ahead for widespread BIM adoption. What are the problems with BIM applications? What consequences will they lead to? That concludes our discussion. I hope this article provides valuable insights!
