|Fundament / Tiefgründung|
A pile is a slender timber, concrete, or steel structural element, driven, jetted, or otherwise embedded on end in the ground for the purpose of supporting a load. A pile is also characterized as deep foundation, where the loads are transfered to deeper subsurface layers.
NOTE Definition according to
ISO 6707-1: slender structural member, substantially underground, intended to transmit force(s) into
loadbearing strata below the surface of the ground.
NOTE Shallow foundations, which transfer the loads to the ground near its surface, are represented by IfcFooting.

|PredefinedType|| : ||
The predefined generic type of the pile according to function.
IFC4 CHANGE Attribute made optional. Type information can be provided by IfcRelDefinesByType and IfcPileType.
|ConstructionType|| : ||
IFC4 CHANGE Material profile association capability by means of IfcRelAssociatesMaterial has been added. The attribute ConstructionType should not be used whenever its information can be provided by a material profile set, either associated with the IfcPile object or, if present, with a corresponding instance of IfcPileType.
|CorrectPredefinedType|| : ||
Either the PredefinedType attribute is unset (e.g. because an IfcPileType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
|CorrectTypeAssigned|| : ||
If this occurrence is defined by a type object, the latter has to be an IfcPileType.
