Basic Civil Engineering

Explain the importance of Surveying and Mapping in construction projects.

• Surveying and mapping are primarily used for aesthetic purposes in construction

• Surveying and mapping are essential for accurate measurements, property boundaries, site planning, obstacle identification, and proper alignment in construction projects.

• Surveying and mapping are only necessary for large-scale projects

• Surveying and mapping do not impact project timelines

What are the different types of surveys used in Surveying and Mapping?

• Geodetic Surveys

• Cadastral Surveys

• Aerial Surveys

• Topographic Surveys, Boundary Surveys, Construction Surveys, Control Surveys, Hydrographic Surveys

What role does a Structural Engineer play in the construction of buildings?

• Painting walls

• Scheduling appointments

• Ensuring safety, designing structural framework, analyzing stresses, overseeing construction

• Cooking meals

Discuss the significance of accurate measurements in Surveying and Mapping.

• Accurate measurements in Surveying and Mapping are essential for ensuring precision and reliability of collected data, which is crucial for various applications.

• Accurate measurements are not important in Surveying and Mapping

• Inaccurate measurements do not impact the quality of Surveying and Mapping data

• Approximate measurements are sufficient for Surveying and Mapping

In a mortar, the binding material is

• cement

• water

• sand

• air

Bitumen is

• solid state, is called asphalt

  
  

• semi fluid state, is called mineral tar

  
  

• fluid state, is called petroleum

  
  

• all the above.

  
  

M10 grade of concrete approximates

• 1 : 3 : 6 mix

  
  

• 1 : 1 : 2 mix

  
  

• 1 : 2 : 4 mix

  
  

• 1 : 1.5 : 3 mix

  
  

Curing

• reduces the shrinkage of concrete

  
  

• preserves the properties of concrete

  
  

• prevents the loss of water by evaporation

  
  

• all of the above.
