Sir, this is really helpful. Your video made me get an A in my Surveying Layout Lab, thanks!

Sir, please do a video about open Traverse surveying and how close errors in a precise method

[@bwhog]

Did you take only the one reading on the form or did you go around the corners to make sure the for was the same height all around? So if the laser gives a somewhat imprecise reading and (knowing optics) it widens out over distance, making it even less accurate, what are your thoughts on what range is useful for a laser level before error starts to become excessive.

@@bwhog Well, this was primarily a training video, so I only shot the two items. When doing the real task before filming, I setup in the center of the bldg form so that my shot to the backsight was the longest shot taken during the course of the work (which was still less than 200 feet) and all my other shots at the 4 corners fell inside that backsight distance. Working inside your backsight distance is a great way to ensure you are not extrapolating errors, especially when the backsight distance accuracies are already at or near your task tolerance or max instrument capabilities. Great question!

This was a great video. Every beginner in site work should see this video. Only thing that still confuses me a little is current terms for the same thing like, benchmark known height, height of instrument. Almost need a dictionary for tems....

@@patmccluskey7504 Great feedback, thank you. I’ve been trying to replace the term “height of instrument” with “the elevation of the level line” even though height of instrument or “HI” is such an industry term, it doesn’t translate that well when teaching at the beginner level. I’ll think about glossary of terms videos for different applications, that’s really smart.
