We are begining to being ask to run earthwork quantities by Phase (road/highway projects). I have found to add the subgrade material to another material to have a combine total subgrade surface. This will allow us to do a earthwork surface to surface report. The bad part I run into is the surface to surfae will not allow the use of two(2) boundaries. I create boundaries by using linestrings. One of out project managers that has been trying to fiqure out ways to do earthwork by phase says he using site regions.
Is there any difference from using linestring and site region to run a surface to surface? Can it be possible to run more then one(1) boundary when running a surface to surface earthwork report?
