Entity definition

An IfcCostSchedule brings together instances of IfcCostItem either for the purpose of identifying purely cost information as in an estimate for constructions costs or for including cost information within another presentation form such as a work order.

HISTORY  New entity in IFC2.0.
IFC4 CHANGE  Attribute ID renamed to Identification and promoted to supertype IfcControl, PredefinedType made optional, attributes PreparedBy, SubmittedBy, TargetUsers removed.
Attribute definitions
#AttributeTypeCardinalityDescription G
7PredefinedTypeIfcCostScheduleTypeEnum? Predefined generic type for a cost schedule that is specified in an enumeration. There may be a property set given specifically for the predefined types.
IFC4 CHANGE The attribute has been made optional.
X
8StatusIfcLabel? The current status of a cost schedule. Examples of status values that might be used for a cost schedule status include:
  • PLANNED
  • APPROVED
  • AGREED
  • ISSUED
  • STARTED
X
9SubmittedOnIfcDateTime? The date and time on which the cost schedule was submitted.
IFC4 CHANGE Type changed from IfcDateTimeSelect.
X
10UpdateDateIfcDateTime? The date and time that this cost schedule is updated; this allows tracking the schedule history.
IFC4 CHANGE Type changed from IfcDateTimeSelect.

IfcRoot
1GlobalIdIfcGloballyUniqueId Assignment of a globally unique identifier within the entire software world. X
2OwnerHistoryIfcOwnerHistory? 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.
IFC4 CHANGE  The attribute has been changed to be OPTIONAL.
X
3NameIfcLabel? 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
4DescriptionIfcText? Optional description, provided for exchanging informative comments.X
IfcObjectDefinition
HasAssignmentsIfcRelAssigns
@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
NestsIfcRelNests
@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).
IFC4 CHANGE  The inverse attribute datatype has been added and separated from Decomposes defined at IfcObjectDefinition.
X
IsNestedByIfcRelNests
@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).
IFC4 CHANGE  The inverse attribute datatype has been added and separated from IsDecomposedBy defined at IfcObjectDefinition.
X
HasContextIfcRelDeclares
@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.
IFC4 CHANGE  The inverse attribute datatype has been added.
X
IsDecomposedByIfcRelAggregates
@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).
IFC4 CHANGE  The inverse attribute datatype has been changed from the supertype IfcRelDecomposes to subtype IfcRelAggregates.
X
DecomposesIfcRelAggregates
@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).
IFC4 CHANGE  The inverse attribute datatype has been changed from the supertype IfcRelDecomposes to subtype IfcRelAggregates.
X
HasAssociationsIfcRelAssociates
@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
5ObjectTypeIfcLabel? 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
IsDeclaredByIfcRelDefinesByObject
@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.
IFC4 CHANGE  New inverse relationship, change made with upward compatibility for file based exchange.
X
DeclaresIfcRelDefinesByObject
@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.
IFC4 CHANGE  New inverse relationship, change made with upward compatibility for file based exchange.
X
IsTypedByIfcRelDefinesByType
@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.
IFC4 CHANGE  New inverse relationship, the link to IfcRelDefinesByType had previously be included in the inverse relationship IfcRelDefines. Change made with upward compatibility for file based exchange.
X
IsDefinedByIfcRelDefinesByProperties
@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.
IFC4 CHANGE  The data type has been changed from IfcRelDefines to IfcRelDefinesByProperties with upward compatibility for file based exchange.
X
IfcControl
6IdentificationIfcIdentifier? An identifying designation given to a control It is the identifier at the occurrence level.
IFC4 CHANGE Attribute unified by promoting from various subtypes of IfcControl.
X
ControlsIfcRelAssignsToControl
@RelatingControl
S[0:?]Reference to the relationship that associates the control to the object(s) being controlled. X
IfcCostSchedule
7PredefinedTypeIfcCostScheduleTypeEnum? Predefined generic type for a cost schedule that is specified in an enumeration. There may be a property set given specifically for the predefined types.
IFC4 CHANGE The attribute has been made optional.
X

Concept usage

Approval

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 IfcCostSchedule. 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.



Control Assignment

The Control Assignment concept applies to this entity.

The IfcCostSchedule may be assigned to the following entities using relationships as indicated:

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