Good morning everyone.
I created a template for proposed roadway (Proposed Sidewalk, Driveway, Curb, HMA, Sub grade, etc.) and a template for the existing roadway (Existing pavement, Curb, Driveway, Sidewalk, etc.). I combined both into one template which works perfectly (Took forever but eventually worked). Then I create cross sections and try to calculate earthwork by the "End Volume Method" under Corridor Modeling. I go under the "Classification" tab and I set every existing Component to "Ignore". But for some reason when I run the End Volume Method, the calculations still include the Cut/Fill of the existing Quantities.
The goal is to eliminate the volume of existing sidewalk, pavement, curb since they will be paid for by Individual pay items (such as Curb Removal) instead of Earthwork. Thus I only want the Earth Work Quantity for the Proposed components but I can't get get this.
Could a problem be that I am including the Existing Surface which will calculate the difference between the Existing surface and proposed components? How should I approach this?
I have attached an example image of a cross sections:
Here is a cross section where the volume was calculated between the Existing Surface and all proposed components have been IGNORED. Thus the volume calculated for this cross section is the volume I want to IGNORE.
This next cross section is where the volume was calculated between the Existing Surface and the proposed components. The existing components have been IGNORED. Thus the volume calculated for this cross section is the volume I want to calculate MINUS the existing volume in the previous image:
Any ideas on how I should approach this?

Any other ideas? I am still trying to figure this out and this seems like it is impossible! Is there anyway to make the existing components (By feature) act as a surface?
I was thinking since the program uses the surface/terrain to calculate earthwork is there anyway to add these Existing components by feature as part of a surface? The existing components are "Overlay/striping" components in the template model. Is there anyway this could work in my favor?
I apologize if this doesn't make sense. I am just trying to make this work. It seems impossible.
Daniel:
I need to accomplish the same thing you dealt with. Where you able to resolve it? I created the design corridor model in SS4 and created existing terrain features from the existing dtm for the existing pavements, sidewalk, driveways then applied a terrain templates to give it thickness. I need to exclude these areas when in cut sections since these quantity is being paid in a separate item however I do need to include the quantity when in fill sections. I am using SS2 inroads to calculate the earthwork.
Thank you
