In a construction project, aspect models are created by subcontractors without the ability to establish relationships outside of file boundaries. When coordinating on the complete project with all models incorporated, spatial relationships from elements by different disciplines have to be inferred.
Based on the type of elements and the relationship of the aspect models you would want to be able to infer e.g:
Every column in the architecture model should have an 'equivalent' representation in the structural model
Every column needs to have a reinforcing bar contained in the geometry
Elements of this type cannot intersect with that type
Elements of this type have to touch an element of that type
Given precision and rounding issues these operations have to be assessed under a specified tolerance.
Precision issues:
Construction tolerance, modelling sloppiness
Rounding errors due to matrix multiplication from local placements
