How to determine the percentages of costs for all building materials
In this construction video tutorial, you will learn how to determine the proportion of materials cost to build up 1000 square feet area.
The percentage of cement cost should vary from 16.5 to 17% (labor is included).
The percentage of sand cost should vary from 12.2 to 13.1%.
The Aggregates cost percentage should vary from 7.5 to 8%.
The steel cost percentage should vary from 24.7 to 25% (labor is included).
The finishing work comprises of brickwork, paint and tiles. Their cost percentages are given below:-
Brickwork = 4.5%
Paint = 4%
Tiles = 8.1%
By summing up we get 16.5% (approx).
Therefore, total cost percentage for finishing work is 16.5%.
The fittings works include windows, doors, electrical, sanitary, plumbing. The cost percentages are given below:-
Windows = 3%
Doors = 3.5%
Sanitary = 4.5%
Plumbing = 5.5% to 6%
By summing up, we get 22.9 to 23%.
If you add all the percentages of costs given above, it will lead to 100% (approx).
