Documenting an industrial facility using 3D laser scanning creates a unified spatial data source for various engineering and operational processes. However, the scope, accuracy tolerance, and level of detail required for the resulting model do not need to be identical for every project.
Even when the physical environment is identical, the engineering objectives behind the digital model differ significantly.
Different Purpose, Different Modeling Approach
The information architecture of a model depends directly on the project goals:
- Models for Maintenance & Asset Management: In models designed for facility operations and asset management, equipment placement, asset IDs, system relationships, and access to maintenance logs take precedence. In this scenario, rich data attribution outweighs sub-millimeter geometric complexity.
- Models for New Line Integration: When integrating a new production line into the same plant, the exact geometry of existing piping, tie-in points, structural members, installation tolerances, and clearance zones become critical.
The Core of Scan-to-BIM: Level of Information Need (LOIN)
In Scan-to-BIM and as-built modeling workflows, it is essential to define not only the geometric detail (LOD), but also the exact alphanumeric data and documentation requirements tailored to the project’s purpose.
This principle forms the foundation of the Level of Information Need (LOIN) framework in BIM workflows: Specifying the exact geometric, alphanumeric, and documentation requirements necessary to satisfy a specific project goal without bloat.
Excessive detail does not imply a better engineering model. What truly matters is producing the right detail for the right purpose.
