Following are most asked Construction Interview Questions, Answers and Tips. These sample Construction Interview questions are part of normally asked questionnaire.

Construction Interview Questions:

What do you mean by Low Cost housing?

Low cost housing deals with effective budgeting which helps in reducing the cost construction through locally available materials involving highly improved skills and technology without hampering the performance and living structure. This kind of low cost housing will be done by proper resource management.

Explain building cost?

The basic division in construction cost is mainly building material cost which is 65 to 70 percent and labor cost which is 65 to 70 percent. In low cost housing even building material cost will be very less as the materials will be locally brought. This will be in turn done efficient and with highly improved design.

Which are the areas where cost can be reduced while construction?

Every component in the house should be preplanned and design procedure should be rationalized. This will ensure the reduction in size of the component in the building.

Verify and check whether if the each component is necessary and checked.

Plan each and every component against the wastage of the materials which occurs in the demolition of the house.

Explain Construction reduction of cost through alternative method?

Few areas where construction cost can be reduced is under the following areas.

  • Foundation – Foundation cost comes to almost around 10 – 15 percent of the total building cost.
  • Plinth
  • Walling
  • Rat – Trap bond wall
  • Filler slabs
  • Ferro cement channel / shell unit
  • Jack arch roof / floor
  • Finishing work
  • Conclusion

What is soil engineering?

This engineering mainly deals with various areas related to soil like vibration control, scaper production, earth quantities which are hauled, earth moving, and compaction equipments like rollers. Soil compaction test. This test also involves various tests like sand cone method, load bearing test, bearing ratio, soil permeability, and settlement under foundations. Bearing capacity of the slopes. Depends on the stability of the slopes like cohesion less soils and cohesive soils
