This video is very educative as a beginner i was able to learn how to compute different survey leveling data, Thanks for the tutorial sir, you really make my day for watching this great tutorial.

Dickson queyartey and neil kynaston: I found the 5 Part video to be very informative and well presented, but not without some "blunders" of its own. To calculate percent of slope = (Rise/Run) x 100. The change in elevation between Station 0+00 (ditch) and Station 7+00 (pond) is 2.50 feet. The formula above would then yield (2.50/700) x 100 = 0.36%. Also, my guess is that the elevation of BM "B" was supposed to be 597.65 and not 595.65 as shown. I would go and field verify that myself if I only knew where in Illinois that benchmark was located.

This format is easy for me to read because I have been doing it for a long time my format however eliminate any confusion whatsoever... But this is the format that is taught in classes...

what about the 2 foot error in both this video and the previous?

Very refreshing, Please comment on my method, I did a level run on the LNG tank for settlement when the tank was subjected to hydrostatic test, 4 times , when tank was empty, 1/4 full, , 1/2 full3/4 full and final. We had 16 brass plates embedded equally place around the periphery in the outer projected base of the tank which was 65 mts in dia, I had to shift the instrument 4 times.to around the tank. When ever I shafted the instrument I manage to set in almost mid way so that instrument error was minimised and I fixed a measuring tape in miimeters of good quality matching the graduations, ( between 0.6 mts to 2.00 mts, where max staff reading s are taken) of the level staff graduated in mts ( to avoid observation errors ), so that I could read to last mm. When I ran to and back fly levels most of the times I never got any closing error except a couple of times with + 2 mm I feel these are some tricks of the trade

Thank you for the video! I liked the explanation! I still have a question. Where I use the closed loop circuit? Do you recommend a book where I can read more about it? Thank you!

Thank you for this video tutorial po 😊

Thank you for educative elaboration, but one thing I didn't understand, why do we need to have TP point .why we couldn't continue with sta.6..7..8...etc. instead

Thanks you for your explain

hi im doing a diploma in construction and till now i have struggled to e3ven grasp the basics until i stumbled across this series well done Rod and thank you ever so much is there anywhere i can watch similar videos but more into the calculations and the trigonometry please and maybe in metric system sorry its an Australian thing hahaha?????

these foos are goated 🐐

Hey have u guys ever used the rise and fall table

Very helpfull to me . Plz make video on EDM

It helps me alot 😊

Sir give the vedio on theodolite how to take angles

Fantastic 5 stsrs

very helpful thank you sir

What is the mistake he made at 10:45?

thank Sir give the vedio How to use for Road

Sir please how did you ascertain the NEW SLOPE of -0.36 percent. Thank you

How did you get slope -0.36??

The Earth is flat, and the benchmarks placed by line of sight proves it.

Very nice

Isn't your closure error +2.02' (597.67 - 595.65)?

ăn tết vui vẻ nha

Sir how did you get your slope of .36?

How come you don't account for the curvature of the Earth?

dude sounds like Dr. Phil

Or I am confused or you make me confuse. Why that damn deduction at beginning doesn’t let me follow the rest. And he focus on the error And mistakes and self confidence. Is anyone can tell me is 2 + 4 is 8? Or if you don’t I kill myself. My mind deeply confused! I can not think anymore. Please reset me again. I am begging you?!
