Take-off
from paper plans is done with a digitizer. A
digitizing tablet is a board with a wire mesh grid imbedded into it. When
the 16 Button Cursor is traced over the board, a current is picked up by the
board's grid, and the coordinates of the tracing device are passed on to the
computer. When a plan is taped to the board, and a scale is entered, the
traced plan is converted to actual measurements, and then InSite computes
the area, length and volume calculation on the traced data.
InSite Software Inc. proudly sells
GTCO CalComp
brand digitizers, but we support many other brands with a 32-bit Wintab Driver and a 16
Button Cursor.
Map location points are permanently marked on the paper plan. This allows a plan to be
re-oriented, in case it is ever removed from the digitizer.
Next,
Site Boundary is selected from the
Enter Map menu. The Site Boundary is traced at the point where proposed
would daylight to existing. This assures that no excess calculations are made
outside the boundary and that calculations are complete to the daylight line.
Existing grades are then
entered. Grade information can consist of
spot elevations, contours, and sloping lines. InSite's
Total Site
Triangulation creates surfaces, which are used to generate the Cut &
Fill volumes.
 You
start with 1. Digitize Contour on the menu. Type in the elevation of the contour
on the 16 button cursor, and begin tracing the grade. You can hold down the
tracing key (0) and drag the crosshair along the contour. Repeat for each grade.
InSite
SiteWork can handle contours, spot elevations, and sloping lines. Surfaces can
also be imported from CAD files.
 Proposed
grades are entered the same way as Existing. The grades are entered from
beginning to end without breaking up each subgrade area. We'll handle all of the
subgrade areas later with the Subgrade Feature.
The High Resolution version of the
proposed grades shows the triangulated surface.
Once the Existing and Proposed
surfaces are entered, the Soil
Boring
Data can be entered.
