Estimation
* Labour cost = 25%
* Cement = 13%
* Reinforcement \ Sariya = 10%
* Brick = 12%
* Sand and Aggregates = 5%
* Door and Window = 12%
* Electrical = 8%
* Water and Sewer line = 12%
* Extra = 3%
* For Simple House
Rs. 1000 per sq.ft.
Plot = 1000 sq.ft.
Total Rs. = 1000 * 1000
= 1000000
* For 1000 sq.ft. plot
1. Labour - 25% = 2,50,000 /-
2. Cement - 13% = 1,30,000 /-
3. Brick - 12% = 1,20,000 /-
4. Wood - 12% = 1,20,000 /-
5. Reinforcement/Sariya - 10% = 1,00000 /-
6. Sand and Aggregates - 5% = 50,000 /-
7. Electric fitting - 8% = 80,000 /-
8. Water - 12% = 1,20,000 /-
9. Extra - 3% = 30,000 /-
Total = 10,00,000 /-
* There are two methods to build a house :-
1. Cement- Brick- Method 2. R.C.C - Column beam based method
1.Cement - Brick Method
Per 100 sq.ft
Materials
(a). Brick = 2800 brick
(b). Cement = 30 bags
(c). Sariya = 150 - 200 kg.
(d). Aggregate = 70 cu.ft.
(e). Sand = 175 cu.ft.
2. R.C.C - Column Beam Based Method
Per 100 sq.ft
Materials :-
(a). Brick = 930 bricks
(b). Cement = 40 bags
(c). Sariya = 350 - 400 kg.
(d). Aggregates = 110 cu.ft
(e). Sand = 150 cu.ft
* Reinforcement Weight
Weight of reinforcement / metre = D² / 162
D = diameter of bar
Ex. 10 mm = 10*10/162
=0.625 / meter wt. ( weight )
* Brick Work
Cement ratio - 1: 6 cu.meter = 1.20 bag ( cement ) = 0.25 cu.meter ( sand ) = 480 bricks
* Plaster Work
1/2' plaster ( per sq.meter) - 1 : 6 - sq.mtr. - 0.078 bag ( cement ) - 0.016 cu.mtr. (sand )
* Concrete
C S A
M 20 = 1 : 1.5 : 3 ( 1 mtr.cu. )
C = Cement
S = Sand
A = Aggregate
Cement = 8 bags
Sand = 0.42 mtr.cu.
Aggregates = 0.84 mtr.cu.
