An IfcLaborResource is used in construction with particular skills or crafts required to perform certain types of construction or management related work.
HISTORY New entity in IFC2.0.
IFC4 CHANGE The attribute Skillset has been deleted; use LongDescription to describe the skillset.
The purpose of an IfcLaborResource is to identify a skillset that may be required or used. The skillset identified may be (for instance) charge-hand, foreman, labourer, plumbers mate etc. and provides a designation of a particular level of skill. It can be used to identify the generic type of labour resource that is required for a purpose without having to be specific about the actor (person or organization) providing the resource occurrence. It may be particularly useful when creating an overall plan for a process or processes. For instance, within maintenance or work planning there may be a known task that needs to be done which is planned to require a 'chargehand pipe fitter'. There may be several such labour resources available and so the need to identify which will be used is not necessary at the planning stage.
At a later stage, individual actors can be determined for the labour resources. This is achieved through specifying the actor through IfcActor. The actor is then identified as the labour resource occurrence through the IfcRelAssignsToResource.RelatedResource attribute. The IfcLaborResource provides the IfcRelAssignsToResource.RelatingResource attribute.

| 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.

| 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.
IFC4 CHANGE The inverse attribute datatype has been added. | 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).
IFC4 CHANGE The inverse attribute datatype has been changed from the supertype IfcRelDecomposes to subtype IfcRelAggregates. | X | |
| Decomposes | IfcRelAggregates @RelatedObjects | S[0:1] | References to the decomposition relationship being an aggregation.

| 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 | ? |
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.
IFC4 CHANGE New inverse relationship, change made with upward compatibility for file based exchange. | 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.
IFC4 CHANGE New inverse relationship, change made with upward compatibility for file based exchange. | 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.
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 | |
| 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.
IFC4 CHANGE The data type has been changed from IfcRelDefines to IfcRelDefinesByProperties with upward compatibility for file based exchange. | X | |
| IfcResource | |||||
| 6 | Identification | IfcIdentifier | ? |
An identifying designation given to a resource.
It is the identifier at the occurrence level.
IFC4 CHANGE Attribute promoted from subtype IfcConstructionResource. | X |
| 7 | LongDescription | IfcText | ? |
A detailed description of the resource (e.g. the skillset for a labor resource).
IFC4 CHANGE The attribute LongDescription is added replacing the ResourceGroup attribute at subtype IfcConstructionResource. | X |
| ResourceOf | IfcRelAssignsToResource @RelatingResource | S[0:?] | Set of relationships to other objects, e.g. products, processes, controls, resources or actors, for which this resource object is a resource. | X | |
| IfcConstructionResource | |||||
| 8 | Usage | IfcResourceTime | ? |
Indicates the work, usage, and times scheduled and completed. Some attributes on this object may have associated constraints or time series; see documentation of IfcResourceTime for specific usage. If the resource is nested, then certain values may be calculated based on the component resources as indicated at IfcResourceTime.
IFC4 CHANGE New attribute. | X |
| 9 | BaseCosts | IfcAppliedValue | ? L[1:?] |
Indicates the unit costs for which accrued amounts should be calculated. Such unit costs may be split into Name designations (for example, 'Standard', 'Overtime'), and may contain a hierarchy of cost values that apply at different dates (using IfcCostValue.ApplicableDate and IfcCostValue.FixedUntilDate).
IFC4 CHANGE New attribute. | X |
| 10 | BaseQuantity | IfcPhysicalQuantity | ? |
Identifies the base quantity consumed of the resource relative to assignments.
For crew, labour, subcontract, and equipment resources, this refers to IfcQuantityTime.
For material resources, this refers to IfcQuantityVolume.
