  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!!!
