HISTORY New entity in IFC4.
| # | Attribute | Type | Cardinality | Description | C |
|---|---|---|---|---|---|
| 4 | ScheduleWork | IfcDuration | [0:1] | Indicates the total work (e.g. person-hours) allocated to the task on behalf of the resource. Note: this is not necessarily the same as the task duration (IfcTaskTime.ScheduleDuration); it may vary according to the resource usage ratio and other resources assigned to the task. | X |
| 5 | ScheduleUsage | IfcPositiveRatioMeasure | [0:1] | Indicates the amount of the resource used concurrently. For example, 100% means 1 worker, 300% means 3 workers, 50% means half of 1 worker's time for scenarios where multitasking is feasible. If not provided, then the usage ratio is considered to be 100%. | X |
| 6 | ScheduleStart | IfcDateTime | [0:1] | Indicates the time when the resource is scheduled to start working. | X |
| 7 | ScheduleFinish | IfcDateTime | [0:1] | Indicates the time when the resource is scheduled to finish working. | X |
| 8 | ScheduleContour | IfcLabel | [0:1] | Indicates how a resource should be leveled over time by adjusting the resource usage according to a specified curve. Standard values include: 'Flat', 'BackLoaded', 'FrontLoaded', 'DoublePeak', 'EarlyPeak', 'LatePeak', 'Bell', and 'Turtle'. Custom values may specify a custom name or formula. | X |
| 9 | LevelingDelay | IfcDuration | [0:1] | Indicates a delay in the ScheduleStart caused by leveling. | X |
| 10 | IsOverAllocated | IfcBoolean | [0:1] | Indicates that the resource is scheduled in excess of its capacity. | X |
| 11 | StatusTime | IfcDateTime | [0:1] | Indicates the date and time for which status values are applicable; particularly completion, actual, and remaining values. If values are time-phased (the referencing IfcConstructionResource has associated time series values for attributes), then the status values may be determined from such time-phased data as of the StatusTime. | X |
| 12 | ActualWork | IfcDuration | [0:1] | Indicates the actual work performed by the resource as of the StatusTime. | X |
| 13 | ActualUsage | IfcPositiveRatioMeasure | [0:1] | Indicates the actual amount of the resource used concurrently. | X |
| 14 | ActualStart | IfcDateTime | [0:1] | Indicates the time when the resource actually started working. | X |
| 15 | ActualFinish | IfcDateTime | [0:1] | Indicates the time when the resource actually finished working. | X |
| 16 | RemainingWork | IfcDuration | [0:1] | Indicates the work remaining to be completed by the resource. | X |
| 17 | RemainingUsage | IfcPositiveRatioMeasure | [0:1] | X | |
| 18 | Completion | IfcPositiveRatioMeasure | [0:1] | Indicates the percent completion of this resource. If the resource is assigned to a task, then indicates completion of the task on behalf of the resource; if the resource is partitioned into sub-allocations, then indicates overall completion of sub-allocations. | X |
