What the study found
The study proposes a generalisable Building Information Modelling (BIM) data model for tension-supporting elements such as anchors, soil nails, and rock bolts. It links geometry and metadata to project phases and maintenance needs across the full project lifecycle.
Why the authors say this matters
The authors say BIM in geotechnical engineering is limited by the lack of standardised modelling methods and functional data structures. They present their model as a way to better support project lifecycle information, including maintenance, and note compatibility with common BIM frameworks and data exchange formats.
What the researchers tested
The researchers developed a conceptual data structure using three real-world Norwegian infrastructure cases covering tunnels, slopes, and foundations. They defined Level of Development (LOD) requirements for both geometry and metadata, aligned with project phases and maintenance needs.
What worked and what didn't
The proposed structure is described as expandable, so maintenance-related information from different periods can be added and traced back later. The abstract says it is compatible with parametric design, widely used LOD frameworks, and the Industry Foundation Class (IFC) format for BIM. However, the paper also states that realisation and testing in real projects are still needed.
What to keep in mind
This is presented as a conceptual framework, not a fully validated implementation. The abstract says full validation will be carried out in future infrastructure projects.
