Reporting Cut and Fill Volumes on a Site

Revit can report cut and fill volumes on a site to aid in determining the costs of landscape modification during site development.

Revit reports the values by making a comparison between a surface from one phase and, from a later phase, another surface whose boundary lies within the earlier surface. For example, Revit can compare a toposurface created in Phase 1 and a toposurface created in Phase 2 that lies within the boundary of the surface from Phase 1. (See Project Phasing.)

When you select the later surface and click Element Properties, you see the following instance properties:

• The Cut value is the volume removed (where the later surface is lower than the earlier surface).
• The Fill value is the volume added (where the later surface is higher than the earlier surface).
• Net Cut/Fill value comes from subtracting the cut value from the fill value.

Note: The cut and fill volumes calculated by Revit are approximate, generally providing results with +/- 1% to 2% accuracy.
