These three options for additions allow you to enter costs from the Residential Cost Handbook as follows:
Local Multiplier: Select this check box to apply the local multiplier to the addition’s cost. The costs in the Residential Cost Handbook are National Average costs. You must apply the Local Multiplier to adjust the cost to the local area.
Trend: Select this check box to trend the addition’s cost from its base date to the report date.
Base Date: Enter the date on the Residential Cost Handbook page containing the cost as the Base Date. When you select the Trend option and set the Base Date, Residential Estimator adjusts the cost from this date to the report date.
You can also use the Trend option and Base Date to adjust a cost from another source. Select the Trend option, and enter the date of the cost as the Base Date. This is useful in the following cases:
If the cost is as of a date other than the report date.
If you will be recalculating the estimate at a later date and want the Residential Estimator to automatically update the addition’s cost.
Note: If you select the Trend option, but do not enter a Base Date, Residential Estimator uses the Base Date from the Cost Adjustments screen as the Base Date for the addition.
