A . MARK LOCATIONS
Mark anchor post locations using
the provided post and row
spacing diagram. See Note:
A.
. FLAT SIT ES
Drive posts with single-point,
starting at the east end. Use
location lasers or gps or string line
to keep in a straight line. Use
height lasers to ensure correct
depth, or story sticks if not
equipped. If using a story stick,
ensure measurements are taken
from the relative ground height,
and not a localized
nonconformance, ie. mole hills,
divets, rocks
B.
. UNEV EN GR OUND
For sites with ungraded or rolling
topology, the string method
cannot be used. It is important to
ensure the posts are set to the
correct depths and the finished
system should appear to conform
to the landscape (fig. B). These
posts will need to be measured
individually from the ground to the
top to ensure they are at the
correct height.
In cases in which post locations
can not be marked on the ground
(uneven terrain), it is advised to
have the surveyor mark the
location of every post, rather than
just the beginning and end of
each row.
Note:
For medium to large projects, anchor locations should be
staked by a professional surveyor, who can stake out end
of row post locations to the highest precision.
CONFORM TO THE TERRAIN
Note on Squareness: Ensuring the squareness of the array from early in the project
is essential in preventing problems later into a build.
1.
Make certain the eastern-most anchor set is exactly spaced and perpendicular
to the row.
2.
After installing several anchor sets, measure out a distance (approx. 98 5/8 for
74" North/South spaced Anchors)in the east/west direction.
3.
Now measure from that point to the first back anchor to create a triangle. The
distance should equal approx 123 5/16 for 74" North/South spacing. Deviations
from this indicate out-of-squareness, and should be remedied immediately.
