Defined in File Ifc2x3.h
This class is a nested type of Struct Ifc2x3.
public Ifc2x3::IfcControl(Class Ifc2x3::IfcControl)
IfcActionRequest: public Ifc2x3::IfcControl¶
A request is the act or instance of asking for something, such as a request for information, bid submission, or performance of work.
Requests may take many forms depending on the need including fault reports for maintenance, requests for small works, and purchase requests (where these are to be made through a help desk or buying function).
HISTORY: New entity in IFC2x2 IFC2x4 CHANGE RequestID renamed to Identification and promoted to supertype IfcControl, attributes PredefinedType, Status, and LongDescription added.
Property Set Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Refer to the documentation at the supertype IfcControl and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ActionRequest
Declaration Use Definition The IfcActionRequest may be declared within the project using the IfcRelDeclares relationship where RelatingContext refers to the single IfcProject and RelatedDefinitions contains the IfcActionRequest. Alternatively, if the IfcActionRequest is aggregated within an IfcWorkPlan, then it shall not have a direct declaration relationship (whereas the containing work plan may have a declaration relationship).
Composition Use Definition As shown in Figure 155, an IfcActionRequest may be aggregated into components using IfcRelAggregates where RelatingObject refers to the enclosing IfcActionRequest and RelatedObjects contains one or more components. Aggregation use is defined for the following predefined types:
(All Types): May contain IfcCostSchedule components. 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.
The IfcActionRequest may be nested into sub-items using IfcRelNests where RelatingObject refers to the enclosing IfcActionRequest and RelatedObjects contains one or more sub-items. Nesting use is defined for the following predefined types:
(All Types): May contain IfcActionRequest sub-items. A request may be nested into follow-up requests, in order of issue.

Assignment Use Definition As shown in Figure 156, an IfcActionRequest may be assigned to the following entities using relationships as indicated:
IfcActor (IfcRelAssignsToActor): Person or organization issuing the request such as a tenant or owner.
The IfcActionRequest may have assignments of its own using the IfcRelAssignsToControl relationship where RelatingControl refers to the IfcActionRequest and RelatedObjects contains one or more objects of the following types: IfcActor: Person or organization(s) fulfilling the request such as a facilities manager or contractor.

Approval Use Definition 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 IfcActionRequest. 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.
