HI = BM + .......

• BM

• IS

• BS

• FS

The proposed level of the point (station) after construction

• BM

• IS

• Ground level (GL)

• formation level (F.L)

Arithmatic check in leveling states that ...................................

• 𝛴𝐵𝑆 − 𝛴𝐹𝑆 = 𝛴𝑅𝑖𝑠𝑒 − 𝛴𝐹𝑎𝑙𝑙

• 𝛴𝐵𝑆 + 𝛴𝐹𝑆 = 𝛴𝑅𝑖𝑠𝑒 − 𝛴𝐹𝑎𝑙𝑙

• 𝛴𝐵𝑆 − 𝛴𝐹𝑆 = 𝛴𝑅𝑖𝑠𝑒 + 𝛴𝐹𝑎𝑙𝑙

• 𝛴𝐵𝑆 + 𝛴𝐹𝑆 = 𝛴𝑅𝑖𝑠𝑒 + 𝛴𝐹𝑎𝑙𝑙

• Staff reading

• Length of leveling route

• HI

• None of the above
