Calculating overbuild areas for takoffs

User Q & A (Post Here)
1

I was wonder what methods are being employed to quantify overbuilds for materials such as ag base. This requires creating a SI (site improvement) that has material layers such as:
Earthen Topsoil- 4”
Earthen Mass- 8” (curb & paving thickness - 4” topsoil)
Ag Base- 6”
Geotextile

This requires a ton of manual report correction because both Earthen Topsoil and Earthen mass are treated as offsite materials rather than being calculated in Topsoil and Mass Earthwork.

The other option is creating a Landscape SI. That does not solve the Earthen Mass calculation and technically is placing all materials above the Topsoil material layer.

Just wondering if I’m missing another method that doesn’t require manually correcting the report more than I already have to for other issues like accounting for select fill below minimum depth when the specification states that ‘all fill in the pad area is to be select,’ among others.

This should be taking care of as the same way any other take off is done. More work to offset a line from edge of pavement to the overbuild. Which from what I have seen is some overbuilds are wider than others. Then just make a material for all your over build from top soil to your subgrade. Which would have to include your backfill material. I do wish there was a better faster wat.

I understand how to offset lines, create SI regions and the specified overbuild distance… I’m not sure if you misread my post or I was unclear, but my question is regarding how to get topsoil and earthen materials to report correctly in an overbuild area. Thanks for the reply.

Do you not add top soil to the SI?
