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

2.15 For the leveling shown .. solved.
