8.5.3.7.1 Semantic definition
IfcResourceTime captures the time-related information about a construction resource.
8.5.3.7.2 Entity inheritance
8.5.3.7.3 Attributes
# | Attribute | Type | Description |
---|---|---|---|
IfcSchedulingTime (3) | |||
1 | Name | OPTIONAL IfcLabel |
Optional name for the time definition. |
2 | DataOrigin | OPTIONAL IfcDataOriginEnum |
Specifies the origin of the scheduling time entity. It currently differentiates between predicted, simulated, measured, and user defined values. |
3 | UserDefinedDataOrigin | OPTIONAL IfcLabel |
Value of the data origin if DataOrigin attribute is USERDEFINED. |

IfcResourceTime (15) | |||
4 | ScheduleWork | OPTIONAL IfcDuration |
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. |
5 | ScheduleUsage | OPTIONAL IfcPositiveRatioMeasure |
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%. |
6 | ScheduleStart | OPTIONAL IfcDateTime |
Indicates the time when the resource is scheduled to start working. |
7 | ScheduleFinish | OPTIONAL IfcDateTime |
Indicates the time when the resource is scheduled to finish working. |
8 | ScheduleContour | OPTIONAL IfcLabel |
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. |
9 | LevelingDelay | OPTIONAL IfcDuration |
Indicates a delay in the ScheduleStart caused by leveling. |
10 | IsOverAllocated | OPTIONAL IfcBoolean |
Indicates that the resource is scheduled in excess of its capacity. |
11 | StatusTime | OPTIONAL IfcDateTime |
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. |
12 | ActualWork | OPTIONAL IfcDuration |
Indicates the actual work performed by the resource as of the StatusTime. |
13 | ActualUsage | OPTIONAL IfcPositiveRatioMeasure |
Indicates the actual amount of the resource used concurrently. |
14 | ActualStart | OPTIONAL IfcDateTime |
Indicates the time when the resource actually started working. |
15 | ActualFinish | OPTIONAL IfcDateTime |
Indicates the time when the resource actually finished working. |
16 | RemainingWork | OPTIONAL IfcDuration |
Indicates the work remaining to be completed by the resource. |
17 | RemainingUsage | OPTIONAL IfcPositiveRatioMeasure |
No description available. |
18 | Completion | OPTIONAL IfcPositiveRatioMeasure |
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. |
