7.11.3.3 IfcDeepFoundation

7.11.3.3.1 Semantic definition

Deep foundation is a type of foundation that transfers loads deeper than shallow foundation below the soft soils not capable of bearing the above structure. Depending on the soil strength it might have to reach down to the rock layer.

Deep foundation is a new supertype incorporating the existing IfcPile and the new IfcCaissonFoundation.

Click to show 21 hidden inherited attributes
IfcElement (13)
8 Tag OPTIONAL IfcIdentifier

The tag (or label) identifier at the particular instance of a product, e.g. the serial number, or the position number. It is the identifier at the occurrence level.

FillsVoids SET [0:1] OF IfcRelFillsElement FOR RelatedBuildingElement

Reference to the IfcRelFillsElement relationship that puts the element as a filling into the opening created within another element.

ConnectedTo SET [0:?] OF IfcRelConnectsElements FOR RelatingElement

Reference to the element connection relationship. The relationship then refers to the other element to which this element is connected to.

IsInterferedByElements SET [0:?] OF IfcRelInterferesElements FOR RelatedElement

Reference to the interference relationship to indicate the element that is interfered. The relationship, if provided, indicates that this element has an interference with one or many other elements.

InterferesElements SET [0:?] OF IfcRelInterferesElements FOR RelatingElement

Reference to the interference relationship to indicate the element that interferes. The relationship, if provided, indicates that this element has an interference with one or many other elements.

HasProjections SET [0:?] OF IfcRelProjectsElement FOR RelatingElement

Projection relationship that adds a feature (using a Boolean union) to the IfcBuiltElement.

HasOpenings SET [0:?] OF IfcRelVoidsElement FOR RelatingBuildingElement

Reference to the IfcRelVoidsElement relationship that creates an opening in an element. An element can incorporate zero-to-many openings. For each opening, that voids the element, a new relationship IfcRelVoidsElement is generated.

IsConnectionRealization SET [0:?] OF IfcRelConnectsWithRealizingElements FOR RealizingElements

Reference to the connection relationship with realizing element. The relationship, if provided, assigns this element as the realizing element to the connection, which provides the physical manifestation of the connection relationship.

ProvidesBoundaries SET [0:?] OF IfcRelSpaceBoundary FOR RelatedBuildingElement

Reference to space boundaries by virtue of the objectified relationship IfcRelSpaceBoundary. It defines the concept of an element bounding spaces.

ConnectedFrom SET [0:?] OF IfcRelConnectsElements FOR RelatedElement

Reference to the element connection relationship. The relationship then refers to the other element that is connected to this element.

ContainedInStructure SET [0:1] OF IfcRelContainedInSpatialStructure FOR RelatedElements

Containment relationship to the spatial structure element, to which the element is primarily associated. This containment relationship has to be hierarchical, i.e. an element may only be assigned directly to zero or one spatial structure.

HasCoverings SET [0:?] OF IfcRelCoversBldgElements FOR RelatingBuildingElement

Reference to IfcCovering by virtue of the objectified relationship IfcRelCoversBldgElements. It defines the concept of an element having coverings associated.

HasSurfaceFeatures SET [0:?] OF IfcRelAdheresToElement FOR RelatingElement

Reference to the IfcRelAdheresToElement relationship that adheres a IfcSurfaceFeature to an element. An element can incorporate zero-to-many surface features in one relationship.
