Compatible unit labor filters
Labor filters are used to identify additional labor hours that are required on a compatible unit (CU) for specific site conditions. Site conditions can affect the number of construction hours that are required for a crew to perform a task, such as installing a set pole.
You can implement labor filters by applying either labor adder indicators or labor filters to the compatible unit.
Labor adder indicators
Applying labor adder indicator information is a high-level method of calculating additional labor hours that are required for a task. You apply a percentage variation to the defined effort hours on the compatible unit. The effort hours indicate the time to install, remove, transfer, or abandon the item on the compatible unit. Effort hours equal the number of resources multiplied by the duration. The percentage variation is defined using the Labor Adder options in the Organizations (T&D) application.
When an estimate is generated, the appropriate calculations are made based on the selected Apply Adder Indicators filters, the effort hours, and the percentage adders.
The following table is an example of how labor adder indicators are used to install a pole.
| Site conditions | Additional percentage adder | Hours |
|---|---|---|
| Base installation of a pole | 10 | |
| Energized | 100% | 10 |
| Inaccessible | 40% | 4 |
| Congested | 25% | 2.5 |
| Soil condition is sand | 10% | 1 |
If all the labor adders indicators apply, then the time that is needed to install the pole is 27.5 hours (base of 10 hours additional and 17.5 hours for all of the site conditions).
Labor filters
Applying labor filter information is a detailed method of calculating additional labor hours that are required for a task. For a precise calculation, you enter every combination of labor for the compatible unit. During the estimation process, the correct filters are matched and the appropriated labor hours are selected.
The following table is an example of how different labor filters combinations define the hours it takes to install a pole and remove a pole.
| Labor | Effort hours to install | Effort hours to remove | Labor filters |
|---|---|---|---|
| OHLINE | 10 | 4 | None |
| OHLINE | 21.2 | 4.3 | Hot |
| OHLINE | 14.1 | 4.17 | Energized |
| OHLINE | 16.3 | 6.2 | Soil condition: Sand |
The first row identifies the time that is needed to install and remove a pole in a normal environment.
Every combination of valid filter values must be entered.
