Trust and precise virtual models are fundamental within the delicate sphere of Building Information Modeling (BIM). This is where model validation is vital in the BIM workflow – it is the basis of a refined procedure. However, what do we mean by testing, and why does this procedure matter? Let’s focus on this crucially important aspect of BIM.
What is Model Validation?
In simple terms, model validation is a process of verifying if a BIM model exactly meets the physical and functional parameters of a building. It is the same as a quality assurance of your BIM model. It allows you to be certain that the data is valid, precise, and complete.
Why is Model Validation Important?
Model validation is one of the most important phases in the BIM process. These checks include everything that is required to enhance the quality, safety, and stability of the project. These checks include:
- Clash detection: Verification of the absence of hard or soft interfaces between the geometric characteristics.
- Project information compliance: Ensuring that the model is consistent with client-specific project requirements and specifications.
- Code compliance: Checking that the design complies with regulations on building codes and standards such as accessibility, fire safety, and environmental factors.
Best Practices for Effective Model Validation
Establish Clear Validation Criteria
Establish specific validation standards, metrics, and criteria that fit the project needs and objectives. It guarantees a well-structured approach to model validation and offers an opportunity for an objective review.
Implement Automated Validation Tools
Utilize specialized software tools and plugins as workflow accelerators, i.e. clash detection software, geometrical validation tools, and performance analysis platforms. Automation not only increases efficiency and accuracy in production but also increases scalability.
Foster Collaboration Among Stakeholders
Set open communication and collaboration among project stakeholders to have the exchange of thoughts, feedback, and remedies based on model validation findings. The continuous participation of the entire team results in the establishment of a culture of perpetual development and quality management.
Integrate Validation into Iterative Workflows
Integrate the model validity steps into the iterative design and building activities, making possible the real-time model validation feedback and iterative improvement of the BIM models. Through this agile process, we collect information and solve problems earlier on, resulting in the reduction of impacts that would have occurred otherwise.
Tool Used for Validation
The software that has an integral role in BIM Model checking is Solibri Office. Solibri offers a set of control rules that can be pre-established to ensure compliance of the model with particular statutes.
Conclusion
Overall, model validation is an integral element of BIM workflow. Through verifying the models for correctness and integrity, BIM contributes to the improvement of the quality of construction projects and renders the construction process more efficient.
Remember that the final result of a construction project is highly dependent on the BIM model quality. Therefore, do not underestimate the significance of model validation!
