hi and welcome to the old school
construction survey and I'm Francisco
Ferro jr. Construction survey consultant
manager one of the most important tools
on any construction site is
communication back in the days before
communication radios surveyors devised a
system of communication for their job
sites hand signals we're just as an
important survey tool is their
instruments such as levels transits
measuring chains tripods and so on
well in today's world with all the new
technology it would seem that hand
signals can be obsolete no longer
considered I disagree I have found
throughout my experience no matter how
improve the technology maybe they can
still be undependable also the use of
radios in a high decibel work zone is
usually unreliable I use hand signals
throughout my job sites and it has
improved the production time
considerably on every project so today
I'm going to show you the basic standard
hand signals for surveying
try it on your job site and find out how
much you can improve with your survey
services okay the first set of hand
signals I will show you are the numbers
now there are two sets of hand signals
for numbers one for working inside a
building or close quarters but still or
too far or too loud for voice
communication and the other the more
common outdoor open hand signals so
you're the first set of hand signal
numbers for indoor work this would be
one two three this is four five six
seven eight nine zero now again these
were used for indoor work now the more
common numbered hand signals would be
these one two three four five six seven
eight nine and zero now some surveyors
would use decimal point indoor would be
a one hand punch and the outdoor would
be a two-hand punch now these were used
to distinguish decimal either decimals
of a foot or meters to centimeters and
millimeters the only problem is that if
the receiver is too far away they may
not be able to see that particular
signal so what I have taught my teams
are is to give their measurements and
either one hundredths of a foot or in
millimeters depending on what part of
the world you're at let me give you some
examples if I want them to do a
measurement of 145 feet even then it
would be one four five zero zero with
the last two numbers be to the hundreds
of a foot that way they always know that
it's 145 feet and no hundreds or if it's
145 meters then it would be one four
five zero zero zero which would take it
down to millimeters okay now another
important note to bring up is that your
hand signal gestures need to be concise
and clear
just throw in your hands up and whatever
way can cause wrong measurements and
costly errors for example this is how
your hand signals should look like you
always begin with your two hands on your
chest and you create
your hand signals whatever number you
give you bring it back to your chest and
then do the next number back to your
chest
the next number back to your chest the
next number this will make it concise
and clear and there will be no there
will be no conflict or whatever as to
what the numbers you're giving out okay
so now now that we know our numbers I'm
going to show you other hand signals
that will communicate to you on what to
do with these particular measurements so
here we go the first thing is
measurement this is a sign for
measurement this is a sign for going
away from me or going away from the
instrument this is come to me or come
towards the instrument these are two
very very important signals now the
other ones are this is top this is toe
this is ground okay and this is the
bottom now some other hand signals
you've got your left and you've got your
right notice that it is my right so when
you give a left it is the left of the
receiver and this is the right of the
receiver
another important thing on curves
usually you're going to give information
or gather information at the point occur
which is a PC the quarter point half
point three quarter point and at the PT
point of transit so PC would be this
signal quarter point would be this
signal half point would be this signal
three quarter points would be this
signal and this would be point of
transit so now at other times when you
need when you forgot some of your survey
instruments or the Rodman and forgot
some of his particular instances as a
hammer or the tape measure chain or
marker these are a couple of things they
can say they can sit there and they can
go come to me with a hammer or again it
means measurement but it also means tape
go another one is the marker well they
sit there and they do that with a marker
that means I'm
my marker so let's put it all together
let's say I want a team to go away from
the gun from the instrument twenty
twenty feet and forty five hundreds so I
will sit there and I'll say distance or
measurement and then I will go away from
the gun which would be two zero four
five
that's twenty forty five away from the
gun then I will sit there and this means
repeat and then this means what did I
say and they will repeat to me what I
just given them now if they give me the
wrong number and I will do this
which means no good erase do-over and I
will repeat the same distance and the
same measurements that he needs to go he
will repeat it back to me and then if
it's good I'll and that means this is
good and so these are just a couple of
very simple and standard hand signals so
now that you have the old-school survey
tool of hand signal communication you
can eliminate time loss on situations
such as radio batteries going dead and
the survey crew would have to come back
to the office and grab new batteries or
if their layouts are taking too long
because they can't hear each other over
the loud Construction noises hand
signals are still a very good and
efficient procedure for construction
surveyors but don't take my word for it
try it out and see the results for
yourself also go ahead and search
through my website and you'll find my
book on cost-effective construction
survey for the contractor it is a
guidebook to give you some tips on
better managing your construction
surveying for your job sites thank you
This Video on Surveyor Hand Signals should definitly be watched by ALL crew members, as stated in the video, this can save you VALUABLE time and possibly ease your frustrations on the jobsite when tiodays technology fails for one reason or another!!!
Excellent Tutorial!!!
