How to calculate separated earthwork volumes in fill situation?

[hamidatut72]

Here I have an issue with calculating earthwork volumes. We Pay to the contractor by compaction percent (95%, 90%, 85%) with different costs (for example 2$, 1.5$, 1$) respectively. so its important to calculate these volumes under the subgrade level in fill situatin (see 2 attach pictures). so how can i create such assembly? i will appreciate if you can help.

You should be able to do this without a new subassembly. 

Create a volume surface for each range. Then filter each surface for the desired elevation ranges for the compaction. Then create surfaces at elevation zero and then depths of the layers, and compare the volume surfaces to this surface. This should then give you the volumes you are looking for. 

You may have to create the volume surfaces and then paste it into a new surface.

Thanks for your reply, I am not able to create volume surface. because I don't have each of surfaces that I'm looking for, I just have the subgrade surface. before everything I must find my surfaces.In fully fill situation I can add some subassembly below the subgrade and calculate the volumes. so when I'm not in fully fill situation (the first attached pic.), I'm in trouble.

Then a second corridor with the appropriate link slope to surface subassemblies to the EG or FG surface. 

If you can deal with side slope quantities included, then the attached drawings will get the values you are looking for.

Thank you very much. its work properly.
