Volume and Grading Calculations - HELP

I'm working on a project for work in which we are constucting a berm.  Material is going to be hauled off and placed in area during construction.  I am trying to establish the area for 1,000,000 cubic meters of material to be placed.  I have a base surface (existing elevations) and a few feature lines created.  I need to fill the berm up to 10m and then place the remaining material up to 15 cubic meters and then sloped off to 10m.  Can anyone tell me what grading/volume options and figure lines I need to use?  Or a link to figure this out.   I was able to calculate the volume for filling it up to 10m, but can't seem to create a surface.

Any help is appreciated!! Thanks!!

You need to draw us a picture so we understand what you're asking...

I'll say I couldn't get past the first 10 meters.

Thank you

I have attached a pdf of the grading plan and a profile view I need to produce to verify the surfaces.

I have figured out everything I needed for filling up to 10m of fill, I did a figure line at elevation 10 around 10m contour and did a fill in on grading.  It created a surface and use volume calculations to subtract the base surface from the 10m surface.  I finally got this all to display on a profile view.  (The volume of the pond was calculated by hand.)

What I'm really having trouble with is the steps to go about dumping material after 10m.  I will have about 650,000m3 of material to dump in layers, 3m thick, starting on the west side. Is it possible to create a profile on profile view and then convert that to a surface?   Or is there some way to create an area (w/ figure line) and raise the grade by 3m but not to exceed 15m?  I don't necessarily need step by step, just help in what direction to go!

THANKS!

I would probably build a simple corridor and corridor surface using a linkWidthAndSlope and a daylight sub to build the berm. Make an alignment an profile along one of the bottom paths. LinkWidthandSlope to get the 10 m height and daylight back to eg.

You can also use the feature lines by creating a stepped offset to get the berm ridge 10m up. Add the two bottom and one (or more) top feature line to a new surface as breaklines.
