Top 10 Basic And Important Interview Question & Answer From Surveying Engineering

Some Basic or Important Interview Questions and Answers Based on Surveying (Civil Engineering)

SURVEYING ENGINEERING

Q.- Differentiate between Plane surveying and Geodetic surveying.      

PLANE SURVEYING

  • The surveys in which the earth’s surface is assumed as a plane surface and earth curvature is ignored are called plane surveys.

 GEODETIC SURVEYING.

  • The surveys in which curvature of the earth is taken into account and a higher degree of accuracy in linear, as well as angular observations, is taken are known as geodetic surveys.

 

Q.- What is M.S.L?

The mean sea level datum obtained by making hourly observations of the tides at any place over a period of 19years is as MSL.

Q.- What is the baseline in surveying?

The longest of the chain lines used in making a survey is generally regarded as a baseline.

              

Q.- Explain the fundamental principles of surveying.

  1. To work from whole to part.
  2. To fix the positions of new stations by at least two independent processes.

 

Q.- Explain the difference between a plan and a map.

PLAN

  • The plan is constructed by usual orthographic projections, disregarding the earth’s curvilinear surface.
  • A plan is drawn on a relatively large scale.

MAP

  • If the scale is relatively small, a plan is called a map.
  • A map generally shows some additional features such as relief, and contour lines to indicate undulations on the ground.

 

Q.- What is the purpose of Cadastral Surveys?

Fixing of property lines, to show boundaries of fields, buildings etc. This is to be done by a revenue engineer.

 

Q.- What do you understand by Scale in surveying?

Scale is the fixed ratio that every distance on the plan bears with the corresponding distance on the ground. For example, 1cm = 10m

 

Q.- Name different types of chains used in chain surveying.

  1. Metric Chain
  2. Gunter’s Chain
  3. Revenue Chain
  4. Engineer’s chain

 

Q.- Explain centring in surveying.

The process of setting up the instrument exactly above the station mark. Plumb bob is made use of.

 

Q.- What are bathymetric curves?

When the contours are drawn underwater, they have termed submarine contours, fathoms or bathymetric curves.
