Height of Instrument Method in Levelling | HI Method| Reduced Levels | Surveying

Height of Instrument is one of the important method to find out the Reduced Levels (RL's) of the ground. This method is also known as Collimation method. In this video detailed method of how to calculate RL's is explained thoroughly with the help of figure, solving a numerical, how to enter surveyed readings in field book and applying arithmetic check.
At 18.38 min for 150 chainage for change point 1 (CP1) by mistake of slip of tongue i have said RL-BS but it is RL+BS and calculations are correct thereafter, only pronunciation i have made slight mistake, humble apology from my side

Thanks for the lesson, it's very educative. But with some observation at cp1 we should be adding the BS to the RL to derive the HI, which you did in application. But in explanation you have told your students to minus, which might b a point of confusion for beginners.

[@structuralanalysisanddesign]

Welcome

[@kelvinkayuni8331]

Thanks alot sir. Why do we prefer height of instrument method during leveling than the rise and fall method?

[@structuralanalysisanddesign]

Because of simpler calculation, rise and fall becomes little tedious, but it is upto you, you can choose any method

[@jyotiacademy2022]

Sir, everything is well-illustrated but I doubt if change point or turning point is the point where the instrument is set. As per my studies, it should be that point where first Foresight is taken from one instrument setting and then foresight is taken from another instrument setting.

[@mushanyisimutowe4207]

I didnt get it sir, First you said for calculating the HI , we are to use the formula HI=Rl+BS right ? but following your presentation at 18.48 min you say we subtract the RL - the BS how is that?

Hello Puja thanks for watching video, i will clear your doubt. is video mai maine clear kiya hai ki agar staff reading ya staff dikhayi na de toh hame instrument utha kar aise jagah par rakhna hai jahan staff hame instrument station se dikhayi de, iska matlab saaf hua profile kaise bhi ho agar staff dikhayi na de tab CP hota hi hai
