2.15 For the leveling shown below, calculate adjusted reduced levels for all points in the level table 
Expert Answer ♥♥♥
ANSWER 2.15
For all station,
HPC = known Reduced Level + Backside
Reduced level/RL = HPC – (IS or FS)
Now, for calculation Checks,
(Sum of all backside/BS) – (Sum of all Foreside/FS) = (Last reduced level/RL) – (First reduced level/RL)
= 7.528 – 7.009 = 66.636 – 66.117 = 0.519
For correction
Net Correction = Actual final RL – Calculated final RL = 62.629 – 66.636 = -4.007
Number of stages = No of BS = No of FS = 4 in this case
There4, correction = =
= -1.00175
Correction in stage one (red) = 1 X Correction = -1.00175
// // two (green)= 2 X Correction = -2.0035
// // three (yellow) = 3 X Correction = -3.00525
// // Four (blue) = 4 X Correction = -4.007
For all Reduced Levels,
Corrected RL = Calculated RL + Correction
