What will be the cost of modular brick wall masonry?/ Rate analysis of modular brickwork.

 Let us consider modular brick wall masonry as shown in the drawing for calculation purposes.



Given data:

Length of the brick wall = 4m.

Height of the brick wall = 3m.

The thickness of the brick wall = 200mm. = 0.20m.


The total volume of the brick wall masonry

= length × height × thickness

= 4m. × 3m. × 0.20m..

= 2.40 cum.


The total area of brick wall

= length × height 

=4m. × 3m. 

12 sqm.


A.  Material calculation:

Read the article " Brick, cement, & sand calculations for modular brick masonry." before proceeding further.

       No. of bricks required/ cum. of wall = 500 nos.

      No. of Cement bags required/ cum. of wall = 1.261 bags

      The volume of sand required/ cum. of wall = 0.2628 cum.

Note :

 The requirement of bricks, cement & sand per cum. is taken from the above-mentioned article.

1. No. of  bricks required 

      = [vol. of brick wall × bricks/ cum.]

      =  [2.4 cum. × 500 nos.]

     = 1200 nos.


2. No. of  cement bags required 

        = [vol. of brick wall × cement / cum.]

      =  [2.4 cum. × 1.261bags]

     = 3.0264 bags


3. The volume of sand required 

  = [vol. of brick wall × sand/ cum.]

      =  [2.4 cum. × 0.2628 cum.]

     = 0.6307 cum.


B.  Labor calculation:

The labor rate per cum. of the modular brick masonry ranges from INR 130/- to 210/- depending upon the region.

Let us consider an average rate of INR 170/- per sqm.


The total cost of labor for modular brick masonry

   = total area of brick masonry in sqm.  × labor rate/ sqm.

   = 12 sqm. × 170/-

   = INR 2,040/-

Now, let us calculate the total cost of modular brick masonry in table format.

                                                       Add 5% wastage =

        562.48

8.

                                                   Total material cost =

10.

    The total cost of modular brick masonry =

   13,851.98

 

Note: To get accurate results, insert your regional market rate of materials & labor, in the above table.

a. The cost of modular brick wall masonry/sqm.

= [total brick masonry cost ÷ total brick wall area]

= 13,851.98 ÷ 12

= INR 1154.33 /sqm.


b. The cost of modular brick wall masonry/cum.

= [total brick masonry cost ÷ total vol. of the brick wall]

= 13,851.98 ÷ 2.4

= INR 5771.66 /cum.


c. The cost of modular brick wall masonry/sq ft.

= [1154.33 ÷ 10.764]

= INR 107.24 / sq ft.


d. The cost of modular brick wall masonry/cu ft.

= [5771.66 ÷ 35.3147]

= INR 163.44 / cu ft.
