IfcRoot
1	GlobalId	IfcGloballyUniqueId	[1:1]	Assignment of a globally unique identifier within the entire software world.	X
2	OwnerHistory	IfcOwnerHistory	[0:1]	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, NOTE only the last modification in stored - either as addition, deletion or modification.	X
3	Name	IfcLabel	[0:1]	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.	X
4	Description	IfcText	[0:1]	Optional description, provided for exchanging informative comments.	X
IfcObjectDefinition
	HasAssignments	IfcRelAssigns @RelatedObjects	S[0:?]	Reference to the relationship objects, that assign (by an association relationship) other subtypes of IfcObject to this object instance. Examples are the association to products, processes, controls, resources or groups.	X
	Nests	IfcRelNests @RelatedObjects	S[0:1]	References to the decomposition relationship being a nesting. It determines that this object definition is a part within an ordered whole/part decomposition relationship. An object occurrence or type can only be part of a single decomposition (to allow hierarchical strutures only).	X
	IsNestedBy	IfcRelNests @RelatingObject	S[0:?]	References to the decomposition relationship being a nesting. It determines that this object definition is the whole within an ordered whole/part decomposition relationship. An object or object type can be nested by several other objects (occurrences or types).	X
	HasContext	IfcRelDeclares @RelatedDefinitions	S[0:1]	References to the context providing context information such as project unit or representation context. It should only be asserted for the uppermost non-spatial object.	X
	IsDecomposedBy	IfcRelAggregates @RelatingObject	S[0:?]	References to the decomposition relationship being an aggregation. It determines that this object definition is whole within an unordered whole/part decomposition relationship. An object definitions can be aggregated by several other objects (occurrences or parts).	X
	Decomposes	IfcRelAggregates @RelatedObjects	S[0:1]	References to the decomposition relationship being an aggregation. It determines that this object definition is a part within an unordered whole/part decomposition relationship. An object definitions can only be part of a single decomposition (to allow hierarchical strutures only).	X
	HasAssociations	IfcRelAssociates @RelatedObjects	S[0:?]	Reference to the relationship objects, that associates external references or other resource definitions to the object.. Examples are the association to library, documentation or classification.	X
IfcObject
5	ObjectType	IfcLabel	[0:1]	The type denotes a particular type that indicates the object further. The use has to be established at the level of instantiable subtypes. In particular it holds the user defined type, if the enumeration of the attribute PredefinedType is set to USERDEFINED.	X
	IsDeclaredBy	IfcRelDefinesByObject @RelatedObjects	S[0:1]	Link to the relationship object pointing to the declaring object that provides the object definitions for this object occurrence. The declaring object has to be part of an object type decomposition. The associated IfcObject, or its subtypes, contains the specific information (as part of a type, or style, definition), that is common to all reflected instances of the declaring IfcObject, or its subtypes.	X
	Declares	IfcRelDefinesByObject @RelatingObject	S[0:?]	Link to the relationship object pointing to the reflected object(s) that receives the object definitions. The reflected object has to be part of an object occurrence decomposition. The associated IfcObject, or its subtypes, provides the specific information (as part of a type, or style, definition), that is common to all reflected instances of the declaring IfcObject, or its subtypes.	X
	IsTypedBy	IfcRelDefinesByType @RelatedObjects	S[0:1]	Set of relationships to the object type that provides the type definitions for this object occurrence. The then associated IfcTypeObject, or its subtypes, contains the specific information (or type, or style), that is common to all instances of IfcObject, or its subtypes, referring to the same type.	X
	IsDefinedBy	IfcRelDefinesByProperties @RelatedObjects	S[0:?]	Set of relationships to property set definitions attached to this object. Those statically or dynamically defined properties contain alphanumeric information content that further defines the object.	X
IfcControl
6	Identification	IfcIdentifier	[0:1]	An identifying designation given to a control It is the identifier at the occurrence level.	X
	Controls	IfcRelAssignsToControl @RelatingControl	S[0:?]	Reference to the relationship that associates the control to the object(s) being controlled.	X
IfcProjectOrder
7	PredefinedType	IfcProjectOrderTypeEnum	[0:1]	Predefined generic type for a project order that is specified in an enumeration. There may be a property set given specificly for the predefined types.	X
8	Status	IfcLabel	[0:1]	The current status of a project order.Examples of status values that might be used for a project order status include: PLANNED REQUESTED APPROVED ISSUED STARTED DELAYED DONE	X

Concept usage

Approval Association

The Approval Association concept applies to this entity.

Approvals may be associated to indicate the status of acceptance or rejection using the IfcRelAssociatesApproval relationship where RelatingApproval refers to an IfcApproval and RelatedObjects contains the IfcProjectOrder. Approvals may be split into sub-approvals using IfcApprovalRelationship to track approval status separately for each party where RelatingApproval refers to the higher-level approval and RelatedApprovals contains one or more lower-level approvals. The hierarchy of approvals implies sequencing such that a higher-level approval is not executed until all of its lower-level approvals have been accepted.

Property Sets for Objects

The Property Sets for Objects concept applies to this entity as shown in Table 251.

PredefinedType	Name	Properties
CHANGEORDER	Pset_ProjectOrderChangeOrder
MAINTENANCEWORKORDER	Pset_ProjectOrderMaintenanceWorkOrder
MOVEORDER	Pset_ProjectOrderMoveOrder
PURCHASEORDER	Pset_ProjectOrderPurchaseOrder
WORKORDER	Pset_ProjectOrderWorkOrder

Table 251 — IfcProjectOrder Property Sets for Objects

Aggregation

The Aggregation concept applies to this entity as shown in Table 252.

PredefinedType	RelatedObjects	Description
	IfcCostSchedule	A cost schedule may indicate costs and quantities where the cost schedule type may designate whether rates and/or quantities are estimated or final. Such cost schedule may have assigned cost items indicating detail, where each cost item may have assigned products, processes, or resources.
WORKORDER	IfcWorkSchedule	A work schedule may indicate tasks and scheduled times where the work schedule type may designate whether tasks and/or times are planned or actual. Such work schedule may have assigned tasks indicating detail, where tasks may be assigned to products and may have assigned resources.

Table 252 — IfcProjectOrder Aggregation

As shown in Figure 160, an IfcProjectOrder may be aggregated into components.

Object Nesting

The Object Nesting concept applies to this entity as shown in Table 253.

Type	Description
IfcProjectOrder	May contain subordinate orders, particularly change orders indicating contract amendment in order of issue.

Table 253 — IfcProjectOrder Object Nesting

Control Assignment

The Control Assignment concept applies to this entity.

Figure 273 illustrates IfcProjectOrder assignment relationships as indicated:

IfcActor (IfcRelAssignsToActor): Organization issuing the order such as an owner or contractor.

The IfcProjectOrder may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcProjectOrder and RelatedObjects contains one or more objects of the following types:

IfcActor: Organization(s) contracted to fulfill the order, typically a single contractor, subcontractor, or supplier.
