Q: The offset should not be longer than
  • A. 30 m
  • B. 20 m
  • C. 15 m
  • D. 10 m
Correct Answer: Option C - Maximum length of offset should not be more than tape used. However generally maximum length is limited to 15 m. The length of offset mainly depends upon– (a) The scale of the plan (b) The accuracy desired (c) The maximum permissible error in eye judgment in laying out the direction of the offset. (d) The error in chaining.
