Cost Calculating Method

The Cost column on the Treatments screen specifies the method by which the cost is calculated. The method is selected from a drop-down list that contains the available unit-cost calculations. Out of the box, the system provides the following two methods to calculate the total cost from unit cost:

• Unit_Cost * Lane Miles
• Unit_Cost * Sq Feet

Additional methods can be configured through Calculated Expressions.
