Base slab (Rough)

Rough dimensions according to structural engineering for base slabs in design development and permitting stages.

Description

• Coarsely dimensioned base or raft slab according to the structural concept.
• Used for coordination between architecture and structural engineering, not for execution planning.

Modelling guidelines

• Model as a simplified volume; split at component boundaries.
• Do not model reinforcement, foundation details, or layer build-ups.
• Early: concept via sketches as structural sketch in the architecture model; verify exclusion zones from the structural engineer.
• Later: align the same components with Reference in the structural model as well.
• Use an IfcMaterial that corresponds to the actual material class.
