Plan Takeoff 5: Civil takeoff: chainage, levels and cut and fill
Civil quantities follow an alignment. Chainage gives every point a distance along it, and comparing existing ground with design levels gives the cut and fill.
How to
- 1
Set out the chainage
Trace the road or pipe alignment on the plan so every point along it has a chainage, its distance from the start.
- 2
Enter the levels
Read existing ground and design levels at each chainage from the long section or plan.
- 3
Calculate cut and fill
Map Metra compares existing and design levels along the alignment and gives cut and fill volumes.
- 4
Carry to the BOQ
Earthworks volumes flow into the Bill of Quantities with the rest of the takeoff, ready to price.
