6.5.3.3 IfcCostSchedule

IfcCostSchedule
Kostentabelle

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.

Object Approval

The Object Approval 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:
