IfcSlab
What is IfcSlab?
IfcSlab represents a horizontal construction element that forms the floor, roof, or landing of a building. Slabs can be classified as floor slabs, roof slabs, landing slabs, or base slabs (foundations). They are typically the largest elements by area in a building model.

Real-World Usage
Slab elements are key for structural analysis, concrete quantity takeoffs, and formwork planning. Construction teams track slab pours by zone, monitor curing schedules, and verify reinforcement details against structural drawings.

IfcWall
IfcWall represents a vertical construction element that bounds or subdivides spaces. Walls are one of the most fundamental building elements in any IFC model, defining the physical envelope and internal partitioning of a building. IfcWall can represent both load-bearing structural walls and non-load-bearing partitions.
Building ElementIfcColumn
IfcColumn represents a vertical structural member that transmits loads from beams and slabs to the foundation. Columns are key elements in the structural grid of a building and can be made of concrete, steel, timber, or composite materials.
Building ElementIfcBeam
IfcBeam represents a horizontal or inclined structural member that carries loads primarily by bending. Beams span between columns, walls, or other supports and are fundamental to the structural system of a building. They can be made of steel, concrete, timber, or composite materials.
Spatial ElementIfcBuildingStorey
IfcBuildingStorey represents a single floor level within a building. It defines the vertical organisation of a building and contains all elements located on that storey. The elevation property defines the height of the storey relative to the building reference point.
Building ElementIfcFooting
IfcFooting represents a foundation element that distributes structural loads from columns or walls to the ground. Footings can be pad footings (isolated), strip footings (continuous), or mat/raft foundations depending on the soil conditions and structural loads.
