What will be the cost of 9″ brick wall masonry
Let us consider 9″ thick brick wall masonry as shown in the drawing for calculation purposes.
Given data:
Length of the brick wall = 16ft.
Height of the brick wall = 10ft.
The thickness of the brick wall = 9″ = 0.75ft.
The total volume of the brick wall masonry
= length × height × thickness
= 16ft. × 10ft. × 0.75ft.
= 120 cu ft.
The total area of brick wall
= length × height
=16ft. × 10ft.
= 160 sq ft.

before proceeding further.
No. of bricks required/ cu ft. of wall = 12.36 nos.
No. of Cement bags required/ cu ft of wall = 0.0353 bags
The volume of sand required/ cu ft. of wall = 0.2593 cu ft.
Note: The quantity of bricks, cement & sand per cu ft. is taken from the above-mentioned article.
1. No. of bricks required
= [vol. of brick wall × bricks/ cu ft.]
= [120 cu ft. × 12.36 nos.]
= 1483.20nos.
2. No. of cement bags required
= [vol. of brick wall × cement / cu ft.]
= [120 cu ft. × 0.0353bags]
= 4.236 bags
3. The volume of sand required
= [vol. of brick wall × sand/ cu ft.]
= [120 cu ft. × 0.2593 cu ft.]
= 31.116 cu ft.

B. Labor calculation:
The labor rate per sq ft. of the brick masonry ranges from INR 12/- to 20/- depending upon the region.
Let us consider an average rate of INR 16/– per sq ft.
The total cost of labor for 9″ brick masonry
= total area of brick masonry in sq ft. × labor rate/ sq ft.
= 160 sq ft. × 16/-
= INR 2,560/-
Now, let us calculate the total cost of brick masonry in table format.
Sl. no. | Item. | Qty. | Rate.
in INR. |
Unit. | Cost
in INR. |
1. | Red brick | 1483.20 | 8/- | Nos. | 11,865.60 |
2. | Cement | 4.236 | 380/- | bag | 1,609.68 |
3. | Sand | 31.116 | 60/- | Cu ft. | 1,866.96 |
4. | Curing | Lump-sum | 250.00 | ||
5. | Miscellaneous | Lump-sum | 200.00 | ||
6. | The material cost = | 15,792.24 | |||
7. | Add 5% wastage = | 789.61 | |||
8. | Total material cost = | 16,581.85 | |||
9. | Labour cost = | 2560.00 | |||
10. | The total cost of 9″ brick masonry = | 19,141.85 |
Note: To get accurate results, insert your regional market rate of materials & labor, in the above table.
The cost of double ( 9″ ) brick wall masonry/sq ft.
= [total brick masonry cost ÷ total brick wall area]
= 19,141.85 ÷ 160
= INR 119.64 /sq ft.
The cost of double ( 9″ ) brick wall masonry/cu ft.
= [total brick masonry cost ÷ total vol. of the brick wall]
= 19,141.85 ÷ 120
= INR 159.52 /cu ft.
