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.

A.  Material calculation:

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.
