earthwork volume calculation

[abhalkip]

I am new to this forum and like to try here for helps.
Anyone pls help to calculate the cut/fill volume for me to comfirm again
the result in my calculation.I am afraid it might be the wrong answer.

I need the earth volume to be removed from the site at a platform level of 29m.
Attached herewith a dwg and crd files

Warm regards and thanks in advance.

I could not attach the files here! The extension dwg and also the file is not allowed.why?
Anyone that are willing to spend a few minutes to do the calculation, I can send it directly
to your emails.
Thanks again.
