Key Considerations for Quality Control in BIM Models (Using Revit as an Example)
When performing quality checks on Revit models, four primary interactive views are commonly used: schedule, plan view, section view, and 3D view. Each view is best suited for identifying specific types of errors.
1. Plan View
Using view templates, you can set the types and display methods of components based on the inspection specialty and items. A well-structured and accurate view setup during model quality checks ensures no inspection steps are missed. Pre-established inspection views also help maintain consistency, preventing discrepancies caused by different BIM inspectors.
2. Structural Plan View Settings
The structural plan view focuses on verifying the dimensions and layout of structural elements such as columns, beams, floor slabs (thickness and extent), and walls (thickness and extent). This view is primarily used to detect drawing errors in the structural model. It exclusively displays structural columns, beams, floors, and walls.
3. Floor Plan View Settings
The floor plan view is mainly used to check the dimensions and positions of painted walls, floors, door and window structural columns, structural beams, as well as the thickness and coverage of structural floors and walls.
4. Ceiling Plan View Settings
For ceiling plan reviews, focus on the net height, materials, and coverage of the ceiling. Use annotation tools within the ceiling view to mark the net height and material. Inspectors then systematically verify ceiling components for errors along a defined inspection path.
5. 3D Section View Settings
3D sectional views are primarily for visually inspecting geometric integrity and logical consistency. After identifying a problematic model element by its incorrect ID, a 3D view can be created around that area. Depending on the components relevant to the inspection, transparency adjustments are applied to non-focused elements to enhance clarity.
6. Section View Settings
When inspecting the building structure, it is recommended to set walls to at least 50% transparency in section views. This reduces the occlusion effect walls have on the main structure in 3D views, allowing construction errors in structural elements to become visible. Consistent coloring should also be applied to highlight these errors.
7. Ensuring Model Inspection Completeness
Case studies show that BIM models can cover tens of thousands of square meters. Without a structured inspection plan, there is a risk of missing errors during the review process. Therefore, based on the identified errors, it is essential to develop inspection paths or procedures referencing the building’s component composition to ensure thorough model verification.
That concludes the overview of key quality control considerations for BIM models, using Revit as an example. I hope this article provides valuable insights to help you improve your BIM model inspections!
