Correct Answer - Option 2 : Multiplying plinth area with the height of the building
The following are the methods used for preparation of approximate construction cost estimates:
- Plinth area method
- Cubical contents method
- Unit base method
Plinth area method:
The cost of construction is determined by multiplying plinth area with plinth area rate. The area is obtained by multiplying length and breadth (outer dimensions of building).
Cubical Contents Method:
The cost of a structure is calculated approximately as the total cubical contents (Volume of buildings) is multiplied by Local Cubic Rate.
The volume of building is obtained by multiplying plinth area with depth or height of building. The area is obtained by multiplying length and breadth (outer dimensions of building).
Unit Base Method:
According to this method the cost of structure is determined by multiplying the total number of units with unit rate of each item. The unit rate is calculated by dividing the actual expenditure incurred or cost of similar building in the nearby locality by the number of units.
