Planning de travail

An IfcWorkPlan represents work plans in a construction or a facilities management project.

HISTORY  New entity in IFC2.0

A work plan contains a set of work schedules for different purposes (including construction and facilities management). Contained work schedules are defined through the IfcRelAggregates relationship. Through inheritance from IfcWorkControl it is also possible to define references to activities (for example, IfcTask) and resources used in the work plan.

A work plan has information such as start date, finish date, total free float, and so on. IfcWorkPlan can also refer to the construction project represented by the single IfcProject instance (please also check the definition of IfcWorkControl).

Figure 109 shows the backbone structure of a work plan that defines (1) contained work schedules through IfcRelAggregates and (2), if not assigned otherwise to contained work schedules, assigned tasks and resources through IfcRelAssignsToControl.

Attribute Definitions:

PredefinedType : Identifies the predefined types of a work plan from which the type required may be set.

Formal Propositions:

CorrectPredefinedType : The attribute ObjectType must be asserted when the value of the IfcWorkPlanTypeEnum is set to USERDEFINED.
