13.5 BATTER BOARDS
When
setting
out
points,
particularly
for
building
plots,
it
is
usually
necessary
to
mark
a
point
with
an
offset
so
that
the
point
can
be
re
‐
established
after
work
has
been
carried
out
in
the
work
area.
In
this
case
batter
board
can
be
used:
the
intersection
point
(of
a
batter
board
and
the
line
that
connects
two
points
that
have
to
be
set
out)
can
be
marked.
Later,
the
intersection
points
are
used
by
pulling
a
string
line
between
these
points.
In
this
way,
the
required
points
can
be
reconstructed.
●
There
are
two
ways
to
proceed:
First
way
is
using
two
sides
of
the
batterboard.
The
user
is
advised
to
use
this
method
in
case
high
accuracy
is
required,
control
of
the
measurements
is
required
or
one
batterboard
is
used
to
mark
more
than
one
intersection
point.
Refer
to
Chapter
13.5.1.
Second
way
is
using
one
side
of
the
batterboard.
The
user
is
advised
to
use
this
method
in
case
a
quick
method
is
required.
Refer
to
Chapter
13.5.2.
13.5.1 Method 1: Batter board using two sides
The
two
sides
of
batterboard
should
be
measured
now.
Put
the
reflector
above
one
side
of
the
batterboard,
enter
a
number
for
this
point
(BB
point
2)
and
press
Enter.
Operating
Procedure:
(A)
Two
setout
point
(S1
and
S2)
are
selected
and
one
side
of
the
batterboard
is
measured
(BB1).
(B)
The
other
side
of
the
batterboard
is
measured
(BB2)
。
The
intersection
point
of
the
batterboard
and
the
line
connecting
S1
and
S2
is
calculated.
Next,
the
distance
(D1)
from
BB1
to
intersection
point
and
the
distance
(D2)
from
BB2
to
intersection
point
are
calculated.
