Previously, we’ve discussed many challenges related to BIM import, mainly focusing on potential problems. However, we rarely address practical solutions. Today, let’s explore how to effectively resolve issues encountered during BIM import in real-world projects.
1. BIM Standards, Specifications, and Contract Templates
Currently, there is a lack of comprehensive BIM-related standards and contract templates. To address this, it’s essential to compile relevant standards and specifications tailored to the current stage of BIM import. Key priorities should include the BIM Acceptance and Delivery Standard, BIM Unit Responsibilities and Obligations Specification, BIM Technology and Implementation Standard, BIM Model Authorization and Use Standard, and the BIM Dispute Resolution Methods and Guidelines.
2. Insurance Clause Considerations
The absence of specific insurance clauses related to BIM is a notable issue. It is expected that the insurance industry will adapt once the technology matures. For now, contracts should clearly define responsibility allocation and compensation limits concerning BIM model development. Additionally, exclusion and exemption clauses specific to BIM models should be included. However, before discussing responsibility and insurance, it is crucial to confirm the purpose and scope of BIM use.
3. Overcoming Old Habits
One significant barrier to BIM adoption is professionals’ attachment to existing methods and processes. Research shows that these ingrained habits pose a more serious challenge than technical, cost, policy, or legal issues. To overcome this, enhancing BIM education and training is vital to foster a shared understanding and integration of BIM concepts across teams. Moreover, while introducing the Integrated Project Delivery (IPD) model in China remains difficult, starting with a unified package model is recommended.
4. Responsibility and Risk Allocation
Changes in responsibilities and risks among owners, design units, and manufacturers need careful consideration. It is important to distinguish between risk and responsibility:
- Owners: They are not responsible for changes. BIM reduces design and construction errors, improves interface integration, and thus lowers risks for owners.
- Design Units: They must provide more detailed information to manufacturers, increasing their responsibilities. While this reduces design error risks, it also raises the risk of providing incorrect data.
- Construction Units: Their responsibility increases for building structural, mechanical, and electrical models. Although BIM reduces construction errors and related risks, there’s an increased risk of quotation errors due to the complexity and volume of BIM data compared to traditional drawings, especially during bidding.
Regarding modeling and management units, they should bear additional responsibilities and risks, but also receive appropriate compensation. For errors caused by using other units’ models, software defects, or integration issues, each unit must establish an audit mechanism. When using external information, audits are necessary, and each unit must take responsibility for its actions and promptly inform the project team of any errors. Responsible parties should be identified and corrections made accordingly.
5. Intellectual Property (IP)
Component ownership remains with their respective authors, who may negotiate royalty fees with owners for usage rights. Each component model’s information provider is considered its author. It is advisable for all project teams to issue authorization letters to other teams, as well as sub-authorization letters to vendors and subcontractors.
Additionally, implementing a registration or application system for component libraries is recommended. A designated authority would handle component registration or applications. Manufacturers who register components gain IP rights, and others must obtain authorization before use.
6. Managing Information Sharing Risks
To protect sensitive information, all units’ information departments should establish internal management and confidentiality protocols aligned with Trade Secrets Law. Project data and archives must be securely managed, with clearly defined processes for receiving and distributing files. Meticulous documentation of issued and received documents is essential to prevent information leakage.
That concludes our overview of practical solutions to BIM import challenges. I hope this article provides useful insights! As I am not an expert, these solutions reflect my current understanding, and I encourage others to contribute their ideas.
