Using the Create Cut Fill Volumes tool, I've successfully figured out how to incorporate not only cut and fill, but existing topsoil stripping, existing pavement removal, rock excavation, and proposed topsoil - all in one shot. It's quite convenient. I'd like to step it up and include proposed storm sewer trench backfill volumes as well. I think I should toggle the Custom option when using the tool, but I'm not sure how that fits in with what I currently have.
I have a 3D roadway/grading model, as well as a 3D proposed storm sewer model. I can get the Cut Fill Volumes tool to include the storm sewer in the cut shape as shown below (blue arrow). I'd really like to separate that shape from the total cut volume (as storm sewer trench excavation is incidental to the storm sewer item, and not included in general cut), and put in two more shapes: one for trench excavation, and one for trench backfill.
If it's not possible to get two additional shapes, getting one for the backfill would be sufficient, as it's an easy calculation to estimate the trench excavation volume from there.
I'm using a DOT ORD workspace. I would think I should see a feature definition for trench backfill, but I don't. This is how was able to incorporate existing pavement, topsoil, etc. I'm thinking I may need to create a new feature definition called Trench Backfill, and set the volume option to Custom. Has anyone tried this before?
Thanks in advance.
Care to share how you set all of these different options up? Feature Definitions tied to your volume meshes? How are you delivering your cut fill data? A Strip Map? Cross Sections or just the 3D Model?
Hello Brian,
I'm not sure if this will completely address your needs, but have you tried creating and applying trench templates for your storm sewer conduits? You will first need to create the trench templates. Then, they can be added to the Feature Definitions for your conduits. After the conduits have been placed using these Feature Definitions, ORD will then generate something very similar (if not identical) to a corridor model for each conduit, and the trench can have different components which you can use to distinguish between different types of backfill. It works well for creating trench quantities. How to combine this with your roadway corridor model - that's a question someone else will have to address - I don't know the answer to that. But with the conduit "corridor models" in place, there may be a way to work them together to get what you want. I hope this provides a piece of the puzzle for you. Attached is a short video from Bentley on applying trench templates once they are part of the conduit's Feature Definition. Good luck, and please share with the Forum the solution once you've figured it out.
Best regards,--Karl
