Earthwork volumes by 1' "lift" increments?

[inhl]

Is it possible to calculate volume by 1 foot "lift increments? Basically I'm tasked with calculating concrete volume of a 200'+/- dam and the owner needs to know how much concrete is in each foot of elevation. Basically how much "fill" is between elevation 0-1, 1-2, 2-3, etc...the other tricky part is the bottom of the dam isn't flat. is this possible?

TIA

Try this for inspiration (probably don't require the dashboard if you aren't on subs)

It most definitely can be done without the volumes dashboard, it is just a lot easier with it. You just have to manually subtract the fill volume of the one calculation from the cut volume of the other calculation. So after you adjust the Level surface, instead of just looking at the dashboard, you have to go to the properties of the one volume surface, record the fill, go to the properties of the other volume surface, record the cut, calculate the different, and then put that into the curve. You might be able to get by with the composite volumes but again, there is definitely some additional data manipulation not needed if you use the volumes dashboard.

does the stage storage analysis do that? By what ever incriment you set the surface?

The Volumes Dashboard is one of the most useful tools for C3D 2012

It won't work for a situation like this because the existing ground is extremely varying (in this case, they are place the tailings from a mine in a canyon). The stage storage tools work greate for ponds but in a situation like this, they fail because the surface expands out and then back together again.

Thanks Brian, but how did you know that from the OP?

I was thinking more along the lines of my blog post. Perhaps for what the OP needs it would work but if the ground the dam is on varies a lot then it probably won't work.

the bottom most definitely isn't flat...as the existing ground has been excavated for the footing. it appears the link above w/ the dashboard method would work as the sample provided doesn't have an flat bottom?? going to give it a shot when i get into the office on monday...

unless someone else has other suggestions? 🙂
