Which the following statements applicable to lead and lift as per IS:1200-part-1-1992 are correct?

1. Lead: Distances not exceeding 250 m should be measured in units of 50 m.

2. Lift: Lift should be measured in units of 1.5 m from the ground level.

  • A.Statement 1 is correct and Statement 2 is incorrect
  • B.Statement 1 is incorrect and Statement 2 is correct
  • C.Both statements are correct
  • D.Both statements are incorrect

Answer: C

Both statements are correct, as the key shows. IS 1200 (Part 1) on the method of measurement of earthwork gives the rule that the lead, the distance that the excavated material is carried, is measured in units of 50 m for distances up to 250 m, and that the lift (the vertical height raised) is measured in units of 1.5 m from the ground level. The options that call either statement incorrect are rejected by the key. I could not check the clause text itself.
