1.    RATIONALE :
      The elementary knowledge of survey will be dealt with in course C - 456, where as in
this course the knowledge & use of the adv. & precise equip. like Theodolite will be given.
Some very quick precise and appropriate methods for conducting survey in odd terrains (like
uneven, hilly, sloping) for any irrigation project, w.s. proj., road project, housing project;
survey is the first & foremost requirement. Hence, this course is very important for the civil
engg. technicians.
