What if you had takeoff/surface groups? You can then run your takeoff report based off a group of surfaces. Your default would look like (the traditional setup):
Takeoff:
- Finished Design
- FD with subgrades absent
- FD with Topsoil absent
- OG with subgrades demolished
- OG with topsoil absent
- Original Ground
- Strata: Ledge
- Strata: Clay
But then you could mix and match:
Takeoff and Measured Strata:
- Finished Design
- FD with subgrades adjusted
- FD with Topsoil absent ( subgrades adjusted)
- OG with subgrades demolished
- OG with topsoil absent
- Original Ground Field Verified
- Strata: Ledge Field Verified
- Strata: Clay Field Verified
- Strata: Unsuitables
Takeoff and Custom Subgrade:
- Finished Design
- Custom subgrade
- FD with Topsoil absent ( subgrades adjusted)
- OG with subgrades demolished
- OG with topsoil absent
- Original Ground
- Strata: Ledge Field Verified
- Strata: Clay Field Verified
This would allow you to keep your original takeoff surfaces and setups with the BC file but also run calcs on different scenarios both purposed and real life.=. This would also be useful for VE situations.
This is something I have struggled with myself on several occasions.
