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.
I agree with this as the closing error is confirmed as 0.02 not 2.02! - however, the principle is still good - thank you for a decent explanatory video.
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...
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!
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 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
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?????
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?!

What's your style of format epild like to learn how to survey better
what about the 2 foot error in both this video and the previous?
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!
4:20, how do you measure the location of those points from the origin? Just a long tape?

Hey have u guys ever used the rise and fall table
Thank you for this video tutorial po 😊
these foos are goated 🐐
Very helpfull to me . Plz make video on EDM
Sir please how did you ascertain the NEW SLOPE of -0.36 percent.
Thank you
Rise divided by run multiply by 100
It helps me alot 😊
Thanks you for your explain
Sir give the vedio on theodolite how to take angles
thank Sir give the vedio How to use for Road
Sir how did you get your slope of .36?
Rise divided by run then multiply that times 100
ăn tết vui vẻ nha
What is the mistake he made at 10:45?
very helpful thank you sir
Fantastic 5 stsrs
Very nice
dude sounds like Dr. Phil
Isn't your closure error +2.02' (597.67 - 595.65)?
Spirit Hawk I was just about to ask the same thing. No mention of whether that is acceptable in this scenario.
@@eddieb9110 Exactly ! He only lists it as 0.02 closure error . What a about the other 2 foot difference ??
The Earth is flat, and the benchmarks placed by line of sight proves it.
How come you don't account for the curvature of the Earth?

How did you get slope -0.36??
