Floor slab (Rough)

ARC-SLAB-FLOOR

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

Description

Coarsely dimensioned floor 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 without layer build-up; split at component boundaries.
Do not model reinforcement, openings, or detail connections.
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.
