# Surface Volumes in specific areas...

258 Views, 20 Replies

I have a 100 acre park that I am doing earthworks.  I have 1 proposed and 1 existing surface.  The park is now broke into 5 different areas and I need to get cut and fill for each area.  Is there a way to do a volume report for a particular area?  I could define the area with a polyline.  Or do I need to copy the proposed surface and start chopping up into 5 areas?

Maybe you should look into the 'Bounded Volumes' option on the Analysis tab. I've never investigated it too much.

Another option is to create new surfaces for your 5 areas. In each case, paste in your proposed surface and then add a boundary. This keeps the link dynamic for easier updating of the design of the proposed surface. And you can use the 'Volumes' analysis to create a report that will list the cut/fill for each surface (each area).

Credit where credit is due! Give kudos or accept as solution whenever you can.

Look into parcels. Since you already have your existing and proposed surfaces done, all you need is a closed polyline for each of your 5 areas, specifiy each area as a different parcel then do a volume calc. It'll give you the volumes for each parcel also.

You don't say what version you are on - the Volumes Dashboard (2012 and later) is the way to tackle this problem or use troma's suggestion (either bounded volumes based on a volume surface or the multiple surface creation method).

I personally wouldn't use the parcels method as I have had bad experiences with parcels in the past but the method does work if you wished to try it.

Just out of curiosity, what kind of parcel problems have you had? I've used it a few times and the volumes are always accurate out when check them via a second method.

Not a problem with the volumes just the parcels - but probably from poor linework causing problems in creation.

Thanks.  That sounds like a great approach.  I made a quick parcel but could not figure out how to get cut and fill quantities.  Could you shed a bit more info on how to do it?

Thanks... What do you think might be the reason it stops a quarter the way thru?

Without any data it's difficult to be sure....
