Detailed Description

A slab is a component of the construction that can enclose a space vertically. The slab can provide the lower support (floor) or upper construction (roof slab) in any space in a building. Only the core or constructional part of this construction is considered to be a slab. The upper finish (flooring, roofing) and the lower finish (ceiling, suspended ceiling) are considered to be coverings. A special type of slab is the landing, described as a floor section to which one or more stair flights or ramp flights connect.

There are two main representations for slab occurrences: IfcSlab with IfcMaterialLayerSetUsage is used for all occurrences of slabs, that are prismatic and where the thickness parameter can be fully described by the IfcMaterialLayerSetUsage. These slabs are always represented geometrically by a 'SweptSolid' geometry (or by a 'Clipping' geometry based on 'SweptSolid'), if a 3D geometric representation is assigned IfcSlab without IfcMaterialLayerSetUsage is used for all other occurrences of slabs, particularly for slabs with changing thickness, or slabs with non planar surfaces, and slabs having only 'SweptSolid' or 'Brep' geometry, or if a more parametric representation is not intended

Body Clipping Geometry - The following constraints apply to the 'Clipping' representation: Solid: IfcExtrudedAreaSolid is required, Profile: IfcArbitraryClosedProfileDef, IfcRectangleProfileDef, IfcCircleProfileDef, IfcEllipseProfileDef is supported Extrusion: The profile can be extruded perpendicularly or non-perpendicularly to the plane of the swept profile Boolean result: The IfcBooleanClippingResult is supported, allowing for Boolean differences between the swept solid (here IfcExtrudedAreaSolid) and one or several IfcHalfSpaceSolid

The image below illustrates a 'Clipping' geometric representation with definition of a roof slab using advanced geometric representation. The profile is extruded non-perpendicular and the slab body is clipped at the eave.

Body SweptSolid Geometry - The following constraints apply to the 'SweptSolid' representation:

Solid: IfcExtrudedAreaSolid is required Profile: IfcArbitraryClosedProfileDef, IfcRectangleProfileDef, IfcCircleProfileDef, IfcEllipseProfileDef is supported Extrusion: The profile can be extruded perpendicularly or non-perpendicularly to the plane of the swept profile

For polygonal slabs, the following interpretation of dimension parameter applies: IfcArbitraryClosedProfileDef.OuterCurve: closed bounded curve interpreted as area (or foot print) of the slab.

The image below illustrates the slab body extrusion.

Element Decomposition - A slab can be decomposed into parts such as for structural framing and covering panels or topping. For efficiency, each part can reuse geometry using the mapped geometry concept. The image below illustrates how a timber construction slab decomposed into parts.

The image below illustrates section showing a slab made from precast hollow core panels.

This concept can be applied to the following resources: IfcBuildingElementPart - Parts for other elements IfcBeam - Precast hollow core planks or double tee beams in concrete construction, or joists and bearers in timber construction IfcCovering - Concrete or topping screeds IfcPlate - Used for metal decks at the base of slabs or sheathing

Element Voiding - The image below illustrates openings within an aggregated slab which are directly assigned to IfcSlab using IfcRelVoidsElement pointing to IfcOpeningElement and apply to all aggregated parts. If individual parts have cutting and other voiding features, then the decomposed parts have a separate voiding relationship IfcRelVoidsElement pointing to IfcVoidingFeature.

Material Layer Set Usage - The image below illustrates assignment of IfcMaterialLayerSetUsage and IfcMaterialLayerSet to the IfcSlabType and the IfcSlab occurrence.

It is illegal to assign an IfcMaterialLayerSetUsage to an IfcSlab. Only the subtype IfcSlabStandardCase supports this concept

Material Set - This concept can be applied to the following resources: LoadBearing Insulation
Object Typing - This concept can be applied to the following resources: IfcSlabType
Product Assignment - This concept can be applied to the following resources: IfcStructuralSurfaceMember - An idealized structural member corresponding to the slab IfcTask - A task for operating on the slab
Property Sets for Objects - Pset_ConcreteElementGeneral Pset_PrecastConcreteElementFabrication Pset_PrecastConcreteElementGeneral Pset_PrecastSlab Pset_ReinforcementBarPitchOfSlab Pset_SlabCommon Pset_TrackBase (only applies to BASESLAB) Pset_CessBetweenRails (only applies to TRACKSLAB) Pset_EmbeddedTrack (only applies to TRACKSLAB) Pset_SlabTypeTrackSlab (only applies to TRACKSLAB)
Quantity Sets - This concept can be applied to the following resources: Qto_SlabBaseQuantities
Spatial Containment - The IfcSlab, as any subtype of IfcBuildingElement, can participate alternatively in one of the two different containment relationships: the Spatial Containment (defined here) the Element Composition
Surface Geometry - The 'Surface' can be used to define a surfacic model of the building (e.g. for analytical purposes, or for reduced Level of Detail representation).
