Excavated site?

[aliya14]

Good Day everyone,
I wanted to know can we calculate the excavated area in a site using schedules options......
Plus when we place a toposurface on the site plan it takes the level as 0'. is there any option where we can change the level where we want to place the toposurface.
Regards,
Aliya

Topography schedules have fields for cut, Fill and Net Cut Fill.

Here is a reprint from the Help file.



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

The way Revit reports the values is 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 between a toposurface created in Phase 1 and a toposurface created in Phase 2 that lies within the boundary of the surface from Phase 1.

When you select the later surface and click Properties, you see three new instance properties: Cut, Fill, and Net Cut/Fill.

The Cut value is the volume removed, or it is where the later surface is lower than the earlier surface.

The Fill value is the volume added, or it is where the later surface is higher than the earlier surface.

Net Cut/Fill value comes from subtracting the cut value from the fill value.

Seeing the Cut/Fill Volumes

This procedure is a general method of reporting cut/fill values. There are other ways to report values, including sketching a new surface within an existing surface.

<LI class=list_1_reset value=1>Create a toposurface in a site plan view. <LI class=list_1 value=2>Select the finished toposurface, click Properties and set its Phase Created value to a phase earlier than the view's phase. For example, set the Phase Created value to Existing while the view's phase is New Construction. <LI class=list_1 value=3>Create a graded region on the toposurface by clicking Graded Region from the Site tab of the Design Bar. <LI class=list_1 value=4>Click the Select and Edit command and select the toposurface. This demolishes the original surface and creates a copy that occupies the same boundary as the original.
When you finish the graded region, select the toposurface copy and click Properties. You see the new cut/fill properties listed for the toposurface.
NOTE: You may need to press TAB to select the copied surface. Also, you may want to apply a Phase Filter to the view that shows only new elements, and not demolished ones.

Cut and Fill in a Schedule

You can create a topography schedule that includes cut, fill, and net cut/fill as schedulable fields. You should also name the different surfaces to distinguish them in your schedule.

Cut and Fill Reporting with Building Pads

If you add a building pad to a graded surface, you will see cut and fill reported separately for the pad and the toposurface in a topography schedule. This is because the pad divides the graded surface into two surfaces: one is the surface under the pad, and one is the surface not under the pad.

You should name both the graded surface and the pad surface in order to distinguish them in your schedule.

To select the surface under the pad, you can press TAB to prehighlight it, or you can turn off the pad's visibility.


When you place a topo surface from scratch, you can enter the absolute elevation of any point. You can also edit the elevation of any point later, or add new points.
If you import data for a topo surface, that data will determine the 3D elevation of the topo points.

Wow! I've been trying to get my arms arond this issue for over a year now. Either they re-wrote the help file and added the functionality dealing with pads, or I really missed something when I was looking last year. So the bottom line is, we can schedule the topo surfaces, show cut/fill totals and include the surface defined by the pad, in order to take into account the amount of fill removed by a pad as well! (Right?) Very excited to try this as it should be valuable in trying to site buildings to balance fill. As long as the "existing" topo data is accurate! ;)
