Explain cubic rate estimate

This method is generally used for multistoried buildings.

• It is more accurate that the plinth area method as height of the building is also taken into account.

• The cost of a structure is calculated approximately as the total cubical contents (Volume of buildings) multiplied by Local Cubic Rate.

• The volume of building is obtained by Length x breadth x depth or height.
• The length and breadth are measured out to out of walls excluding the plinth off set.
• Cost of building= (volume of building) x (rate/ unit volume).
• Eg. (Plinth Area of the building) x (Height (height is taken from the top of the floor level to top of flat roof)) x (Cubic Content rate)

• The cubic content rate can also be deduced from similar buildings constructed in the vicinity of the proposed building project site.

• The foundation, plinth and the parapet above the roof is neglected in finding cubical contents.
