Calculating the construction cost of a compound wall/ Estimating & costing of a compound wall ( part 8 ).

 BACK  PART 7 👈

First, we will sum up the total quantity of materials from all 7 parts series of this compound wall.

 The volume of RCC for compound wall

= [for footings+ for plinth beam + for columns]

= [0.743 cum + 2.75 cum. +1.561 cum.]

=5.054 cum.i.e. 178.48 cu ft.


Let us make this RCC in M20-grade concrete.

The no. of cement bags required for RCC work

= [8.06 bags ×( 5.054 cum ÷ 1 cum )]

= 40.73 bags

The volume of sand required for RCC work

=[ 0.42 cum ×( 5.054 cum ÷ 1 cum )]

=2.122 cum.  i.e. 74.938 cu ft.


The volume of coarse aggregates required for RCC work

= [0.84 ×( 5.054 cum ÷ 1 cum )]

= 4.245 cum. i.e. 149.91 cu ft.


Note: The value i.e. directly added above is taken from "Calculating the quantity of materials in different grades of concrete".


Now, we will sum up the total quantity of cement, sand, & aggregates required for the compound wall construction.

Note: The value i.e. mentioned below are taken from all 8 parts of the series.

  The total number of cement bags for compound wall work.

       = [for PCC + for masonry + for  RCC + for coping]

       = [12.70 +  3.516 + 40.73 + 3.537]

       = 60.483 bags 


The total volume of sand required in the compound work

     = [for PCC + for masonry + for  RCC + for coping ]

     = [31.156 + 25.86 + 74.938 + 8.675]

     =  140.629 cu ft.


The total volume of coarse aggregates required in the compound work.

     = [for PCC + for RCC + for coping]

     = [62.31 + 149.91 + 17.35]

     =  229.57cu ft.


The total weight of rebars required for the compound work.

= for footing + for plinth beam + for columns

=   [43.98 kgs + 260.69 kgs. + 175.9 kgs.]

= 480.57 kgs.


Let us find out the material & labor cost for the construction of a compound wall.

Material cost:


Sl.No.    Description        Quantity    Rate      Unit       Amount

  

1.          Boulder for                    42           23         cu ft.       966.00
             foundation

 2.    Total cement bags     

        for compound work      60.483     380      bag      22983.54     

 3.    Total sand for 

       compound work             140.629     60      cu ft.      8437.74           

 4.   Total aggregates for 

       compound work               229.57       54      cu ft.   12396.78    

 5.    concrete blocks               712             30        no.      21360.00 

 6.   reinforcement                        

        bars                                 480.57         48        kg.      23067.36

        

          Total material cost for compound work =  INR  89211.42



           Labor cost:

Sl.No.   Description        Quantity      Rate      Unit      Amount

 1.     Earthwork excavation          

        for the compound        285.365        5        cu ft.     1426.82

 2.    Boulder soling               42                6        cu ft.       252.00

 3.    PCC work                      70.81          24      cu ft.        1699.44

 4.    Muroom filling            85.102        3       cu ft.         255.306

 5.   RCC work                       178.48        65      cu ft.       11601.2

 6.   Block masonry           338.78          24      cu ft.         8130.72                 

 7.   coping                          19.717            32     cu ft          630.94

              Total labor cost for compound work = INR  23996.43


    The total cost of the compound work = INR 1,13,207.85

   Add 1.5% for water charges & labor for curing =INR 1,698.11

                         Add 10% for contractors profit =INR 11,320.78

    Total expenditure for the compound wall 

                    =INR 1,26,226.74 

Note: The rate of the material & labor changes according to their availability in different regions.


The cost of the compound wall/ r ft. length

 = total expenditure ÷ compound wall length

   = 126226.74 ÷ 140 ft.

   = INR 901.62 / r ft.


The cost of the compound wall / sq ft.

cost per r ft.÷ compound wall height above GL.

 = 901.62 ÷ 6.416 ft.

 = INR 140.52 / sq ft.
