Notes:
Geopak adds the backfill to replace the Undercut into your Embankment quantities.
The Cross-Section Earthwork volume spreadsheet was also designed to work with these templates.
The level symbologies and explanations are below:
Unsuitable Subgrade/Subsoil Excavation (Undercut)
LVName = Prop XS Earthwork Undercut Note: Geopak refers to this Undercut as Subgrade/Subsoil Excavation and will return the quantity as Subsoil excavation. The Cross-Section earthwork volume spreadsheet recognizes this as Undercut.
Unsuitable Common Excavation
LVName = Prop XS Earthwork Unsuitable Unclassified Note: This is not paid for as Undercut and the Cross-Section earthwork volume spreadsheet adds this quantity to Unclassified Excavation.
Rock Line
LVName = Prop XS Earthwork Rock Hard Degradable
LVName = Prop XS Earthwork Rock Hard Nondegradable
LVName = Prop XS Earthwork Rock Weathered Degradable
Limit Line
LVName = Prop XS Earthwork Geopak Lower Limit Line Note: You may want to think of this as the "bottom" of your Rock. Geopak needs this line to compute Rock quantities.
The way Rock is defined in the input file can be a bit confusing, so consider the following:
This is the Limit Line
Existing suitable material
soil type = rock
fill mult factor =
type = line,line_string
lvname = Prop XS Earthwork Geopak Lower Limit Line
This is the Rock Line
Existing suitable material
soil type = suitable
fill multiplication factor =
type = line,line_string
lvname = Prop XS Earthwork Rock Hard Nondegradable
