Phased Earthwork Reporting – Best Practices?

User Q & A (Post Here)

Hey Rockpile fam :construction_worker_woman::man_construction_worker:,

I’m running into a challenge and wanted to see how others have tackled this.

I’m working on a project where the GC requested earthwork reporting to be broken into multiple phases after the full takeoff was already completed. I’ve already built my takeoff in one shot, but now I’m tasked with generating a cut/fill report broken out by Phase 1 and Phase 2.

Here’s what I did:

  • I used AOI boundaries to split the project by Phase 1 and Phase 2.
  • Ran the Volume Report (Grid = 5.000 ft) in TBC.
  • Got some usable totals by phase, but the report still includes bleed-over areas between phases — meaning some scope within the phase boundaries wasn’t calculated cleanly.

What I need to get:

  • Demo scope quantities
  • Mass grade cut/fill totals
  • Subgrade and paving breakouts

Have any of you had success generating clear phased earthwork reporting after takeoff? Is there a better way to cleanly isolate the volumes and avoid mixed results in shared/overlapping areas?

I’d love to hear:

  • Any workflows or settings that helped you get better phase breakouts
  • Tips for structuring AOIs more cleanly
  • How you present phased results to the GC when TBC’s output is muddy

Any input or screen grabs would be gold. :pray:

Thanks in advance — hoping to learn from your experience!

I’d say from my perspective you’ve done it the way I would have. If you just need earthwork numbers, I prefer to use volume manager as it creates the separate cut fill maps for all the phase report regions.
as for overlapping areas it’s super hard to not have any of these in you AOI as 2 lines that sit right on top of each other count as being overlapping, if you have the time after getting all the aoi you offset them inside of themselves by 0.01 that would clean up the overlap assuming they are sharing a single border. keeping naming conventions as short and sweet as possible will help with the reporting. anything I’m sharing outside of myself I generally spend a bit of time formatting it for others consumption

Nudge works fantastic for these tasks.

Can i nudge to the inside, assuming I have a phase land locked by other phases?

you can nudge both left and right of the line as well as ahead and back along the line.

more about the command here: Nudge Line / Nudge Node Command

Nudge is handy for all sorts of various tasks and allows for movement by node instead of the entire line.

You really don’t want to have anything in the “Remaining Area”, instead you want to make another AOI (it could even be called Remaining Area lmao). The takeoff report will not include any of the site improvement material quantities in the totals that are not part of an AOI, if you chose to use AOIs. It seems like a pretty big error in the report to me, but I am assured that is how Trimble meant for it to work. Good luck!

This will be quick. I have done my take off for the beging as OG and Design. Then for phasing, on the OG. I would create my detour if any and combine the OG with the detour. I would have my design join slopes to match the new OG. Its a bit painful but I was picky for Qty on the phasing. I never dealt with the AOI tool for this.
