| Use
the
Quick-Stack™
Subgrades feature to trace site features like parking lots, building pads,
topsoil replacement areas, etc. Since the proposed grades are entered at
finish, we use a Depth
type subgrade for areas like a parking lots to remove an even layer from the
proposed surface. A
Replacement Topsoil
subgrade is similar to a depth type, except the volume of
replacement topsoil is automatically calculated. Use an
Elevation
type subgrade for building pads.
Quick Stack™ Subgrades
Estimators who have switched
from other programs are often amazed how much faster a take-off can be done with
InSite SiteWork. One reason is because of our
Quick Stack Subgrade
feature.
 Follow
along and watch how easy it is to enter this complex site
(These are lower resolution images, the final image can be made
larger).
First, trace the perimeter of the
topsoil replacement footprint. Notice that we are not worrying about the
footprint of the buildings or parking lot. These are handled automatically
later.
For
Subgrade Type, we entered
3.Repl Top
(Replacement Topsoil) with a value of .33 (4 inches). Cut
& Fill will be calculated to a depth 4 inches below the proposed grade, and the
Topsoil replacement volume will automatically be calculated.
Next
we'll enter a subgrade for the parking area. The footprint of the paving area
was traced.
This
is entered as Subgrade Type
of Depth.
The Subgrade Value
is entered as 1.5
feet (the total thickness of the paving materials). We entered the Descriptions
and Thickness for each Subgrade Material (Asphalt and Sub-Base).
Finally
we'll enter each Building pad. Trace the perimeter of the building, and choose
Elevation
from The Subgrade Type
menu. Enter the elevation of the structure.
 InSite
will ignore the proposed surface in this footprint, and calculate a flat pad to
this elevation. You can optionally enter any subgrade materials.
A few More Things about
Subgrades.
1. The Topsoil Replacement
traced first now includes only the maroon area. The buildings and paving are
automatically subtracted from this footprint.
No Double Tracing Required!
2.
Revisions are easy!
Since the proposed grades are independent of the subgrade
areas, if the grades change, just change the grades. If the subgrade footprints
change, just draw the new subgrade.
3. There is a
No-Work Subgrade that can be used for Existing
Structures, a grove of trees, etc. Just trace the perimeter, choose No-Work as
the Subgrade Type, and the traced area is excluded from all earthwork
calculations.
4. There are 90 Subgrades available,
and each Subgrade can have an unlimited number of areas assigned to it as is
needed.
5. The Quick-Stack
feature of InSite SiteWork works the same in CAD
import.
We have now entered most of the site
information. Now let's check the results!
