COURSE DESCRIPTION

Surveying is the most useful and necessary part in Civil Engineering. Students will understand the use of Chains, Tapes, Compass, as well as optical surveying instruments such as Theodolite, Total Stations, Auto Levels and Electronic distance measuring machines. Students will also understand reduction of slope measurements to horizontal and vertical components, field data reduction and adjustment of a closed traverse, horizontal and vertical curves and calculation of earthwork volume.

COURSE OBJECTIVES

  1. To teach the students basics of surveying and expose different techniques of surveying.
  2. To help the students to learn the field applicability of the different survey methods.
  3. To teach students about types of errors encountered in different types of surveying.

COURSE OUTCOMES

On completion of this course, the students will be able to

  1. Prepare Topographical maps & surveyed site plans for civil projects.
  2. They will be able to transfer map/drawing/layout plan on the actual site of civil projects.
  3. They will be able to estimate the earthwork of civil projects.
  4. Carry out tachometry, geodetic surveying wherever situation demands.
  5. Apply error adjustment to the recorded reading to get an accurate surveying output.
