DUMPY LEVEL Procedure On Field

On Field - Video

Calculation :
Bench Mark Level (A)- 1500 mtrs
Dummy Level to Bench Mark Reading (B) - 2 mtrs
Required Floor Level (C)- 1501 mtr's
Measured Reading for the Floor Leveling (D)= 1.5 mtrs

Total Height of DumPy Level (A+B) = 1500 + 2 = 1502 mtrs
There fore Required Measurement from Dummy Level to Floor = (A+B) - C = 1502 - 1501 = 1 mtr

As per the Measured Condition = (A+B) - D = 1502 - 1.5 = 1500.5 mtrs

as per the calculation we need to back fill with a height of .5 mtrs
