What will be the cost of 9" brick wall masonry?/ Rate analysis of 9" thick brick wall work.

  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:

Read the article " Brick, cement, & sand calculations for brick wall masonry." 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.

                                                      The material cost =

  15,792.24

                                                       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.
