What will be the cost of block wall masonry?/Rate analysis of concrete block masonry.

 Let us consider solid concrete block masonry as shown in the drawing for calculation purposes.



Given data:

Length of the block masonry = 16ft.

Height of the block masonry = 10ft.

The thickness of the block masonry = 0.5ft.


The total volume of the block masonry

= length × height × thickness

= 16ft. × 10ft. × 0.5ft.

= 80 cu ft.


The total area of block masonry

= length × height 

=16ft. × 10ft. 

= 160 sq ft.


A. Material calculation:

Read the article "Calculating the quantity of materials in a 100 cubic ft. block wall." before proceeding further.

       No. of blocks required/100 cu ft. of wall = 210 nos.

      No. of Cement bags required/100 cu ft of wall = 1.038 bags

      The volume of sand required/100 cu ft. of wall = 7.634 cu ft.

Note: The quantity of blocks, cement & sand/ 100 cu ft. is taken from the above-mentioned article.

1. No. of  concrete blocks required 

      = [(vol. of block wall ÷ 100 cu ft.) × blocks/100 cu ft.]

      =  [(80 cu ft. ÷ 100 cu ft.) × 210 nos.]

     = 168 nos.


2. No. of  cement bags required 

      = [(vol. of block wall ÷ 100 cu ft.) × bags/100 cu ft.]

      =  [(80 cu ft. ÷ 100 cu ft.) × 1.038 bags]

     = 0.83 bags.


3. The volume of sand required 

=  [(vol. of block wall ÷ 100 cu ft.) × sand/100 cu ft.]

  =  [(80 cu ft. ÷ 100 cu ft.) × 7.634 cu ft.]

6.11 cu ft.


B.  Labor calculation:

The labor rate per sq ft. of the block masonry ranges from INR 10/- to 15/- depending upon the region.

Let us consider an average rate of INR 12/- per sq ft.


The total cost of labor for block masonry

   = total area of block masonry in sq ft.  × labor rate/ sq ft.

   = 160 sq ft. × 12/-

   = INR 1920/-

7.

                                                       Add 5% wastage =

   287.63

8.

                                                   Total material cost =

 6040.23

9.

                                                                Labour cost =

 1920.00

10.

                       The total cost of block masonry =

7960.23

 

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

The cost of block masonry/sq ft.

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

= 7960.23 ÷ 160

= INR 49.75/sq ft.

The cost of block masonry/ cu ft.

= [total block masonry cost ÷ total block wall volume]

= 7960.23 ÷ 80

= INR 99.50/cu ft.
