drive the stake where you can. In this case, you would choose the Offset method. In the Offset example above, we had
to walk past the catch point about 2 units (from 36.50 to 38.56). We drive the stake, and note that the catch is at 956.03
rather than 955.01, so we measure up 1.02 on the stake, and draw a horizontal line there as the catch point. An extra
line appears in the report that tells us to write "Cut 2:1, 10.28 V, 20.56 H" on the stake. In cases of fill where there are
obstructions, walk into centerline so when you drive the stake, you can mark where the fill intersects the stake. Note
that this same level of reporting occurs with "non-interval" staking, where you get real-time cut and fill at any point, also
allowing you to drive the stake to avoid obstructions.
When Enter or OK is pressed, you are prompted for whether to stake the first offset stake.
If you are doing “User-Defined” or “Point-Defined Alignment” methods, you are shown the horizontal distance and
vertical fill or cut difference to the pivot point, which can be written on the Slope Stake. Additional break-point
information appears if you are using the “Design File” or “Section File” method. If you trust that the Slope Stake will
not be knocked out, then you are done—no need to set an offset stake.
Pressing OK leads to the prompt to set the first offset stake. If you choose to set the first offset stake, then you can set
the offset distance.
Press OK and then you are in a standard stakeout screen. The offset point is a fixed location and the stakeout procedure
is similar to point stakeout. This leads to a report of information that can be written on the Slope Stake. Finally, you
will be prompted for staking out a second Slope Stake, to establish “line.” After the first offset stake is set, and before
the prompt for the optional second offset stake, a summary screen will appear. If you have used the Road Design File or
Section File methods, you will be presented with every break point into centerline.
