Allows you to specify the name of a resource to be applied directly to the Schedule Item.

This would be most commonly used when a schedule item does not required a build up using a Cost Estimate.

Estimated Rate

The Estimated Rate column shows the per unit rate of the schedule item.

This is calculated by dividing the Estimated Total by the Quantity of the Cost Schedule item.

Estimated Total

The Estimated Total represents the entire Cost Total of a Schedule Item.

This can be calculated by using a Cost Estimate, a resource applied to the Schedule Item, or both.


This column identifies whether or not a schedule item has been excluded from project calculations and ultimately, from the project altogether.

Item Type

The Item Type column allows you to set how a Schedule Item contributes to the project.

If the Schedule Item has a quantity, then the item can have its Item Type set to either Contributing or Rate Only.

Item State

The Item State column identifies the current status of a Cost Schedule item.

These states can only be applied to Schedule items that are either Contributing or Rate Only.

Items with quantities can have an item state of Unfinished, Checked or Finished.


The Duration column allows you to define a length of time that the item will take to complete.

The value entered within the Duration column will become the value of the automatic define #DUR.

This column is typically used when the item’s Cost Estimate is using a Time based Estimating mode.

If a Cost Schedule item has been indented below another Cost Schedule item, the Parent Line column will show the line number of its immediate parent Cost Schedule item.

Note: This property can be applied to all Overhead Cost Schedule item types.

Anticipated Rate

The Anticipated Rate column is used to enter a user defined preliminary rate for the schedule item. The item needs to have a quantity in order to enter an anticipated rate.

Alternatively this value can also be calculated by dividing the Anticipated Total by the Quantity.

Anticipated Total

The Anticipated Total column is used to enter a user defined preliminary total for the schedule item. The item needs to have a quantity in order to enter an anticipated total.

Alternatively this value can also be calculated by multiplying the Anticipated Rate by the Quantity.
