Just wanted to thank u for ur videos; setting out, two peg test, height of collimation and the others, they were crucial in my Cert IV. Most appreciated.
Great video, for refresher course. Haven't taken out a level in years, always got independent surveyor to do surveys for me. Going back to doing them myself. Explains a lot very easily. Thanks a mill
Been reading the books and trying to make sense of the procedures in the examples, just gave me a massive headache! Thank you. I wish I knew about this video before. Thank you. Can you do more examples? And could you do vertical and horizontal curve ranging by any chance pls?
I've just watched your video. Whether you use, as you did in your example, collimination height, or the alternative rise and fall, it is safer to go from the backsight to each intermediate and foresight, rather than from one to the next, as any error in a calculation going from one to the next will impact all calculations from that point. Going from the back sight to each will only impact the specific calculation where the error was made EXCEPT if it's made at a change point, for those new to taking levels a change point is where you need move the instrument, and the last reading before moving is a foresight, and after resetting up the instrument, you read back to the same point and record it as a backsight. The difference in the readings merely represent the vertical change in horizontal plane of the instrument. The final results will be identical.
I would like to thank you for this helpfull video. Wanna request you for a video which shows how to take levels for rpad work with only one point of instrument station
Hey thanks a lot Mr Buildsum. its' really very helpful and found it interesting following your video's. I took a course in the year 1981 and cut off from all that goes to surveying. I am a bit lost and want to go upon again. So far i can manage to put myself into the picture and what i want to ask about is whether there exist any software for surveying and levelling.
+Kiran Dewoo Hi Kiran I'm sure there is however as i don't do a lot of surveying or leveling I'm not aware of any. i only use a spreadsheet type program like excel or Google sheets.
Kiran Dewoo Hi Kiran, For taking levels, I recommend using a field book, as shown in this video, and either use s calculator or as suggested, use a spreadsheet or similar to do your addition/subtraction to determine your relative levels. Surveying is a different matter. Total stations, which have capacity to measure distances and instantly display horizontal bearing, vertical angle from the asmith (horizontal) actual distance from the instrument to the target being measured, and the horizontal and vertical dimensions to that target. The can record all that information, and depending on instrument can display some of it in graphic form on it's screen. they also can interface to a computer and in some cases directly into programs like Auto cad. That is a big step from taking levels and taking some horizontal measurements using a tape measure or stadia wires if the level has them.
Just wanted to check if you have negative readings (i.e. a negative number is recorded in the table) on intermediate sight, how do you calculate RL for that station?
Hi Angela, inverted readings are recorded as a negitive on the Level book and calculated as a negitive number, so if you minus a negitive number you are effectively adding it on to the HOC. This video may help ruclips.net/video/KoVH6Scb7WA/видео.html
@@laurenxox7419 I wasn’t bashing the video at all. Good stuff. Just commenting that the calculations he seemed to be doing on the side as he poked thru what looked like a spreadsheet can be easily calced automatically with simple cell formulas.
Hi Abdul Assuming that HI is Height of Instrument and IS is Intermediate Sight. For a start, the term Height of Collimation is just another term for Height of Instrument so that might help otherwise the HI for the IS is the same as the FS (Foresight) until you get to a change point. With that information and the video, I think I should have covered your question. Hope this helps
+Alex Mwita Hi Alex thanks for your comments unfortunately i don't know anything about vertical and horizontal curves for road construction so can do a video on that sorry

I'm here in 2021 paying 9k a year for online classes and this video makes much more sense than the videos I'm paying for, thank you :)
Hi Lauren, sorry to hear that, glad that the video is helping.

Watching your videos is like the textbook is coming alive. ❤
Thanks Mate, I'm glad it was helpful.
Thanks Mike
Glad to hear that they are useful for the Civil Eng students.
Hey buildsum, you're a true champion for uploading these videos.
Thank you :)
Hi Mate, thanks for your comment, I'm glad you like them
Thanks for taking the time to create and upload this playlist. Very helpful.

Thank you for saving me form a headache! great video!
Thanx...... You Saved me.....4 my Exam....thanx a lot....
A million thanks sir!

Hi Dennis
Thanks for the suggestion, I have never seen it done this way but as you say the results should be the same.
Cheers pal, helped a lot.
Hi Danny 1389
No worries glad you like it
Thanks for the Feedback
I love you man!!!!!!!
Thanks for the help. I appreciate it.
Thanks, Jackie, no problem at all.
thank you so much sir
Nice work thumbs up!!!!
Brilliant video's thank you very much
Thanks Mate, Glad you like them!
Hi Thinkers Emblem
Thanks for the comment

Cheers mate, You've saved me a lot of reading for my assignment
Buildsum Mine surveying course, part of a mine engineering PDip.
I would like to thank you for this helpfull video.

Thank you.
so helpful
THANK YOU
Two years ago i watched your video, now i'm watching it again.
i wonder if you can give e the excel sheet
God bless you

Thanks, Mate, I'm glad it helps.
better than rading the i will learn by this method easily thank q

I'm assuming also that we all know that Excel's pretty handy for doing this math for you.
Hi, QS student here, probably 3 years late to this but do you mean excel can work it all out for you? if so, how?

@@dave-o3954 no me neither the video has helped a lot, but would really help with my assignment if you could drop the excel formulas👀 thanks :)
Thank You...
thanks Anup, glad you like it.
thank you very much sir. also how we can show the result by drawings ...... thanks alot
Thanks Osman
You can show the results by drawing using these methods

hey bro please also made the videos of fly levelling
THANKS
Thanks Munashe
GOOD video,can u do video on how to set vertical and horizontal curve for roads consrtuction
+Alex Mwita Hi Alex thanks for your comments unfortunately i don't know anything about vertical and horizontal curves for road construction so can do a video on that sorry
okay no problem,i have been searching 4 a good tutorial on setting road curve but i haven't found one
can you please make a video to work out from the bottom up.
Hi Ana, sorry I have never done it or seen it done from the bottom up.
thank you so much
Seems HC is more logical than R&F method?
Hi
I actually like R&F more, no particular reason just my preference.
Damn im using this in 2023
Hope it is still helpful.
Sorry mate. I'm running a Mac. It goes to the internet page but won't allow me todo anything further to that.
***** No worries, refresh and try again now
A whole chapter of levelling and a two hour lecture failed to explain this as well as you did. Thanks
