Topsoil Removal/Replacement
Function
The Topsoil Removal and Replacement options (shown here) allow the user
to Define Topsoil removal and replacement depths, Set topsoil removal
and replacement areas by selecting closed polylines, Clear the selected
boundary polylines if needed, Hatch the topsoil removal and replacement
areas and Erase the hatched areas.
Define Topsoil Depths
This command requires user input to define the depth, or strata, of
topsoil
removal and replacement. Fill in the options available in the Define
Topsoil Depths dialog (shown here). Carlson Takeoff will preform four
functions with these values. First, the value set for the Removal
Depth, or the Top Strata if selected, will be the "defined" removal
amount from the
Existing Ground Surface. Second, the calculated volume of
topsoil removed will be included in the reporting options. Third, the
value set for the Replacement Depth will be added "BELOW" the
Finished
Ground Surface model. Fourth, the amount of topsoil replaced will be
included in the reporting options.
When topsoil depths are defined, the volume report routines will
include the topsoil quantities. These topsoil quantities are in
addition to the cut/fill for the existing to design surfaces for the
site.
The Removal Swell Factor and Replacement Shrink Factor are multiplied
by the topsoil removal and replacement quantities respectively in the
volume report routines. The Density is used to report topsoil tons when
the volume report option for tons is active.
The Topsoil Offset Method choose between offseting the topsoil depth
vertically or perpendicular to the surface. The perpendicular method
will result in more topsoil quantities since it represents applying the
topsoil depth to the slope area of the surface whereas the vertical
method represents applying the topsoil depth to the horizontal area.
Prerequisite: topsoil depths
Keyboard Command: define_topsoil
Identify Topsoil
Polylines
This command allows users to identify topsoil polylines by either
picking on a
polyline(s) or by searching the entire drawing. The command will then
report the layer name and starting point for both removal and
replacement polylines. These polylines are also highlighted in the
plain view.
Prerequisite: topsoil polylines
Keyboard Command: id_topsoil
Report Topsoil Areas
Use this command to report the Inclusion or
Exclusion area (SF), the type, the depth, the
layer, and the starting point.
Prerequisite: topsoil areas
Keyboard Command: report_topsoil
Label Area Of Interest Areas
This command labels the topsoil type and area in the plain view.
Prerequisite: topsoil area
Keyboard Command: label_topsoil
Erase Area Of Interest Labels
This command erases topsoil labeling.
Prerequisite: hatched area of interest
Keyboard Command: erase_topsoil_labels
Set Topsoil Removal Polylines
Use this command to select the "CLOSED" polyline boundary defining the
extents of topsoil removal and any "CLOSED" interior polylines that
will not have topsoil removed. The outer boundary usually is the same
polyline that defined the "Boundary Polyline" selected earlier. The
internal polylines usually are those that have been selected as the
"Exclusion Polylines". The layer names for these boundarys is
irrelevant. You will be prompted to use the Removal Depth defined in
the Define Topsoil Depths command or to customize your depth.
Prerequisite: polylines for removal
Keyboard Command: tag_topsoil_remove
Clear Topsoil Removal Polylines
This command allows the user to remove and previously selected Topsoil
Removal Polyline boundarys.
Prerequisite: topsoil polylines
Keyboard Command: untag_topsoil_remove
Hatch Topsoil Removal Area
Use this command to display a hatch pattern over the entire area
designated for topsoil removal.
Prerequisite: topsoil areas
Keyboard Command: hatch_topsoil_remove
Erase Topsoil Removal Hatch
Use this command to remove the hatch pattern that defined the topsoil
removal area.
Prerequisite: hatched topsoil
Keyboard Command: erase_topsoil_remove
Set Topsoil Replacement Polylines
Use this command to select the "CLOSED" polyline boundary defining the
extents of topsoil replacement, and any "CLOSED" interior polylines
that
will not have topsoil replaced. The layer names for these boundarys is
irrelevant. You will be prompted to use the Topsoil Replacement amount
defined in the Define Topsoil Depths command or to customize your
amount.
Prerequisite: polylines for replacement
Keyboard Command: tag_topsoil_replace
Clear Topsoil Replacement Polylines
This command allows the user to remove and previously selected Topsoil
Replacement Polyline boundarys.
Prerequisite: topsoil polylines
Keyboard Command: untag_topsoil_replace
Hatch Topsoil Replacement Area
Use this command to display a hatch pattern over the entire area
designated for topsoil replacement.
Prerequisite: topsoil areas
Keyboard Command: hatch_topsoil_replace
Erase Topsoil Replacement Hatch
Use this command to remove the hatch pattern that defined the topsoil
replacement area.
Prerequisite: hatched topsoil
Keyboard Command: erase_topsoil_replace
