Slicing the volume of a surface at 1m intervals

We design a lot of Waste storage facilities, mainly above ground level.

 

I need to generate stage storage volumes at one metre intervals.

 

Is there a way to automate this?

Is this what you're looking for?

You should be aware that the precision of the report is based on the precision of the surface contours displayed.

Using the stage storage tool works well for basins, but I can not get it to work when the waste starts breaking ground (in fill).  

What I need is the solid created between two surfaces, sliced at 1m intervals.

I'm guessing that you have two surfaces, excavated existing ground and a top surface for the waste.  If the excavation is a basin then you would be able to get a volume to the surface from that.  The second volume could be calculated using the top surface, from the ground up to the top of the pile.

 

I believe there is a way to create surfaces that would allow for stage storage calculation when the excavation is not a basin but it definitely would not be automated or easy.

OK, I know some of you guys already have certain ideas about me.  What if you visualized this in reverse?  Draw a basin that represents this mound of waste upside down. I'll leave it at that for the time being.

I seem to remember a similar conversation, and Joe-Bouza texted stage storage on a mound instead of a basin. I can't remember the context.

If you want to invert a surface (from a mound to a basin) it should be pretty simple.
1. Create a flat (horizontal, planar) surface.
2. Create a volume surface using your mound as the 'Base' and the flat surface as 'comparison'.
3. Paste the volume surface into a regular TIN surface (you can't use a TIN volume surface for volume comparisons, but maybe you can use it for the stage storage, so this step may be unnecessary).

Thanks for the feedback,

 

I tried inverting the facility as you suggested.  The volume surface shows the correct capacity (= flat surface / design surface - flat surface / existing ground) but, the stage storage data is about half the capacity.  

 

I think it is caused by the uneven ground profile.

 

The attached drawing contains the ground and design contours.
