IfcRelConnectsWithRealizingElements defines a generic relationship that is made between two elements that require the realization of that relationship by means of further realizing elements.
An IfcRelConnectsWithRealizingElements is a specialization of IfcRelConnectsElements where the connecting operation has the additional attribute of (one or many) realizing elements that may be used to realize or further qualify the relationship. It is defined as a ternary relationship.
The connection types for bridges include:
- TrussJoint: Joint between truss members.
- ExpansionJoint: Joint allowing movement, usually due to thermal expansion difference in structures, with DiscreteAccessory of type EXPANSION_JOINT_DEVICE as RealizingElement.
- EmbeddedPartsJoint: Joint for auxiliary parts to structure, with appropriate RealizingElements, such as DiscreteAccessories of type ANCHORPLATE, BRACKET or SHOE.
- ConstructionJoint: Joint for phasing of construction, typically in in-situ concrete structures.
Assignment of a globally unique identifier within the entire software world.
Assignment of the information about the current ownership of that object, including owning actor, application, local identification and information captured about the recent changes of the object,
Optional name for use by the participating software systems or users. For some subtypes of IfcRoot the insertion of the Name attribute may be required. This would be enforced by a where rule.
Optional description, provided for exchanging informative comments.
The geometric shape representation of the connection geometry that is provided in the object coordinate system of the RelatingElement (mandatory) and in the object coordinate system of the RelatedElement (optionally).
Reference to a subtype of IfcElement that is connected by the connection relationship in the role of RelatingElement.
Reference to a subtype of IfcElement that is connected by the connection relationship in the role of RelatedElement.

Defines the elements that realize a connection relationship.
The type of the connection given for informal purposes, it may include labels, like 'joint', 'rigid joint', 'flexible joint', etc.
Ownership, history, and merge state is captured using IfcOwnerHistory.
IfcRoot assigns the globally unique ID. In addition it may provide for a name and a description about the concept.
