Conditions, such as weather or elevation, can affect the performance and productivity of a construction site. An adjustment factor can be applied to IWPs and individual work steps to compensate for any influencing conditions. Adjustment factors calculate the number of hours required to perform a task under project conditions, compared to the number of hours required to perform the same task under standard conditions.
You can add adjustment factors to your entire project in the ROP Configuration.xlsm, workbook. You can also add adjustment factors to individual IWPs and individual work steps in the Smart Construction client. For more information on configuring adjustment factors for IWPs and work steps, see Configure labor adjustment factors for IWPs and work steps. For more information on adding adjustment factors to IWPs and work steps, see Add an adjustment factor to IWPs and work steps.
Adjustment factor rates can be added to the workbook in a reference column to calculate site factors such as weather or elevation.
-
Add columns for each factor value on each tab where you want the reference column.
-
Add rates for each column added.
-
Verify that the correct rates are associated with the correct components.
-
Generate the rules of progress data.
Example
For example, a construction site has a high elevation and cold weather - two factors that affect the unit rate for installation.
In order to compensate for these factors, two reference columns (one for elevation and the other for weather) can be added to the ROP Configuration.xlsm workbook with values determining the effect of the elevation and weather.
The unit rate for installation can be revised to compensate for these factors. The unit rate column for installation can be a formula that multiplies the unit rate by the weather rate and the elevation rate, as seen in the following image:
