Cut/Fill Schedules
As we mentioned earlier, Revit site tools are not meant to replace civil engineering software
programs. We have shown you how to create a topographical surface in a variety of ways as well
as some methods of modifying these objects. There is also a way to quickly quantify how much
earth is displaced by proposed changes to existing topography. This is commonly referred to as
a cut/fill schedule.
One easy way to demonstrate the use of a cut/fill schedule is through the creation of a
building pad that automatically modifies the topographic surface. Let’s go through a quick
exercise to examine this process:

1. Open the file c03-Site-Cut-Fill.rvt, which can be downloaded from this book’s web
page.
In this file, open a default 3D view, select the toposurface, and you will notice that the
topographic surface has been assigned to the Existing phase in the Properties palette.
2. From the View tab in the ribbon, click Schedules and then select Schedules/Quantities to
open the Edit Schedule dialog box.
3. From the Category list, choose Topography, set the Phase to New Construction, and then
click OK.
4. In the Fields tab of the Schedule Properties dialog box, choose Name, Projected Area, Net
Cut/Fill, Phase Created, and Phase Demolished, clicking Add after each one. Click OK to
close the dialog box.
5. While you are still in the working view of the schedule, go to the Properties palette and
set the Phase Filter of the schedule to Show Previous + New. This will allow only the
modified toposurfaces affected by the Graded Region command to appear in the sched-
ule. The complete existing topography will not be listed in the schedule.
