Compound wall cost per Rft & Sqft in India – today we will estimate the cost of boundary wall construction in India, So let’s start…..


Compound wall cost per Rft & Sqft
Given Data,
Size of Plot – 40′ x 30′
Column to column distance – 10ft.c/c
Main Gate size – 10′
Pcc thickness – 4”
Pcc Grade – M15 (1:2:4)
Footing Size – 1.5′ x 1.5′
Footing height below GL – 2.5′
Steel bar diameter in footing – 10mm
Plinth beam size – 9” x 12”
Plinth beam depth below GL with PCC – 7” + 4″ = 11”
Plinth beam depth above GL – 5”
Column size – 9” x 9”
Height of Boundry wall from GL – 6feet
wall thickness – 6”
Coping thickness – 4”
The thickness of rubble soling – 9” or 0.75′
No. of Column required in total Compound wall


Site perimeter/c/c column distance
Site perimeter – Length of wall 1 + Length of wall 2 + Length of wall 3 + Length of wall 4
= 40 + 40 + 30 + 30 – 140feet
So, Total no. of column = 140/10 = 14Nos.
Step no.1 – Excavation quantity
i). Earthwork Excavation
Size of footing – 1.5′ x 1.5′
Excavation both side – 3”
So, the Excavation size of the footing will be – 2′ x 2′
Footing height below GL – 2.5′
Then, the total volume of footing excavation – footing length x footing breath x footing depth (l x b x h)
– 2′ x 2′ x 2.5′ = 10cft
and, total no. of column footing – 14Nos.
So, total the total volume of footing excavation – (footing excavation volume x no. of footing)
– 10 x 14 = 140cft
ii). Plinth Beam Excavation
Plinth beam size – 9” x 12”(LxD)
Lets take both side offset for exacavation of beam – 4”
So, Width of plinth beam – 9″ + 4″ + 4″ =17″ or 1.416ft
Plinth beam depth below GL with PCC – 7” + 4″ = 11” or 0.9166′
Plinth beam depth above GL – 5”
Then, the total volume of excavation – Perimeter of the site – (No. of footing x footing width) x plinth beam excavation width x plinth beam excavation depth
= 140 – (14 x 2′) x 1.416 x 0.9166 (depth below GL)
= 112 x 1.416 x 0.9166 = 145.365Cft
The total volume of excavation for compound wall
= footing excavation + Plinth beam excavation – 140 + 145.365 = 285.365Cft
Step no.2 – Rubble Soling (only in Footing)


The thickness of rubble soling – 9” or 0.75′
Size of footing – 2′ x 2′
Depth of soling – 0.75′
No. of footing – 14Nos.
So, The volume of soling in footing – Footing area x depth of soling x no. of footing
= 2′ x 2′ x 0.75′ x 14 = 42Cft.
Step no.3 – PCC Quantity
i). PCC for footing
Pcc thickness – 4” or 0.33′
No. of footing – 14Nos.
Length of footing – 2′
Width of footing – 2′
The volume of Pcc in footing – l x b x h x No. of footing
– 2′ x 2′ x 0.33′ x 14 = 18.48Cft
ii). PCC for plinth beam


The volume of excavation of beam – 145.365Cft
Pcc thickness – 4” or 0.33′
Plinth beam depth below GL with PCC – 7” + 4″ = 11” or 0.9166′
Volume of pcc for plinth beam – by volume ration with plinth beam excavation
= (0.33/0.9166) x 145.365 = 0.36 x 145.365 = 52.33Cft
So, The volume of pcc for compound wall – Pcc volume of footing + pcc volume of plinth beam
=18.48 + 52.33 = 70.81Cft.
Step no.4 – Materials Calculation PCC Quantity
Given, Pcc Grade – M15 (1:2:4)
The total volume of PCC – 70.81Cft.
First of all, for easy calculation, we will convert Pcc quantity Cft to Cum
To convert Cft to Cum → Multiply by 0.02831 or divide by 35.31
(Because 1Cft = 0.02831Cum)
So, the volume of PCC – 70.81Cft x 0.02831 = 2.004Cum
but it is the wet volume of concrete & to calculate qty of materials first we calculate the dry volume of PCC
Always, remember one thing,
The dry volume of concrete is always 54% more than the wet concrete
So, the dry volume of PCC = 2.004 x 54% = 3.086Cum.
Now, we will calculate the Qty of materials for PCC
i). Cement Quantity
Formula = Volume of dry concrete/Sum of Ratio x Cement ration in the mix
= 3.086/(1+2+4) x 1 =0.441Cum
As you know, the density of cement = 1440Kg/m³
Volume of cement in kg = 0.441 x 1440 = 635.04kg
As we all know, 1 cement bag = 50kg
Number of cement bags = 635.04/50 = 12.70Bags
ii). Sand Quantity
Formula = Volume of dry concrete/Sum of Ratio x Sand ration in the mix
= 3.086/(1+2+4) x 2 =0.8817Cum
To convert the quantity in Cft, multiply by 35.3147 (because 1cum is equal to 35.3147cft)
So, volume of sand = 0.8817 x 35.3147 = 31.22Cft
iii). Aggregates Quantity
Formula = Volume of dry concrete/Sum of Ratio x aggregates ration in the mix
= 3.086/(1+2+4) x 4 = 1.7634Cum
To convert the quantity in Cft, multiply by 35.3147 (because 1cum is equal to 35.3147cft)
So, volume of sand = 1.7634 x 35.3147 = 62.274Cft
Step no.5 – Concrete quantity
i). Concrete volume for footing
Length of footing – 1.5′
Width of footing – 1.5′
The thickness of footing – 0.833
No. of footing – 14Nos.
The volume of footing concrete – L x B x H x no. of footing
– 1.5′ x 1.5′ x 0.833′ x 14 = 26.24cft or 0.743cum
ii). Concrete volume for Plinth beam
The total length of the perimeter is 140′
Width of plinth beam – 9”(0.75′)
Depth of plinth beam – 12”(1′)
Total column footing volume = Column width x Mno. of column
= 0.75′ (9”) x 14 = 10.5cft
So, Volume of concrete in plinth beam = Perimeter length x breadth x depth of plinth beam – Deduction of the volume of column footing
= (140 x0.75 x 1) – 10.5 = 94.5cft
iii). Concrete volume for Column
Column size – 9” x 9”(228mm x 228mm) or 0.75′ x 0.75′
Column height above GL – 6.416ft
Column height below GL – 7” (0.583′)
No. of column = 14Nos.
The volume of concrete in column = l x b x h x no. of column
L x B x (Column height below GL + Column height above GL) x no. of column
= 0.75 x 0.75 x (6.416 + 0.583) x 14 = 0.75 x 0.75 x 7 x 14 = 55.125Cft or 1.561Cum.
Step no.6 – Steel quantity
i). Quantity of steel in footing
Length of footing – 1.5′
Breadth of footing – 1.5′
Number of footing – 14Nos.
Footing thickness – 0.833′
if we consider,
Steel bar diameter in footing – 10mm
Spacing – 5”
Clear cover – 2”
So, the total steel qty of footing = 43.98kg.
ii). Quantity of steel in Plinth beam


Perimeter length of beam – 140′ or 42672mm
Plinth beam size – 9” x 12”
if we consider,
Steel main bar diameter – 12mm@ 4Nos. (2top, 2bottom)
Stirrups – 8mm@150mm c/c spacing
Clear cover – 25mm (for all sides)
So, the total steel qty of plinth beam with stirrups & 2%wastage will be = 260.69kg.
iii). Quantity of steel in Column


Column size = 9” x 9”
Total no. of column = 14nos.
if we consider,
Longitudinal bar diameter – 12mm@ 4Nos.
Stirrups – 6mm@150mm c/c spacing
Clear cover – 40mm
So, the total steel qty of the column with stirrups & 5%wastage will be = 12.564 x 14 = 175.9kg.
The total weight of steel for compound wall
= footing steel qty + Plinth beam steel qty + Column steel qty – 43.98 + 260.69 + 175.9 = 480.57Kg
Step no.7 – Brick & Block masonry quantity


Total length of compound wall = site perimeter – main gate length
= ( 40′ x 2nos.) + (30′ x 2nos) – 10′
= 80′ = 60′ – 10′ = 130feet
The total length of block masonry – compound wall length – (no. of column x width of a single column)
= 130′ – ( 14nos – 0.75′) = 130′ – 10.5′ = 119.5′
Height of boundary wall = compound wall height – coping thickness
= 6′ – 4”(0.33′) = 5.67′
The volume of block masonry = l x h x thickness of the wall
= 119.5 x 5.67 x 0.6(0.5′) = 338.7825cft or 9.593Cum
Brick standard size = 190 x 90 x90mm
No. of red bricks required = 4794Nos.
Cement required in brick masonry – 12Nos.
Sand required in brick masonry – 88.99Cft
No. of concrete blocks required = 712Nos.
Cement required in block masonry – 3.516bags
Sand required in sand masonry – 25.86Cft
Step no.8 – Coping concrete quantity


Coping thickness – 4” (0.33′)
Concrete grade – M15
= Volume – coping length x width x thickness
= Brick masonry length x masonry width x coping thickness
= 119.5′ x 0.5′ x 0.33′ = 19.717Cft or 0.558Cum.
if we consider M15 concrete grade for coping
So, cement required = 3.537bags
Sand required – 8.675cft
Aggregates required – 17.35cft
Step no.9 – Backfilling quantity


i). For Footing – 48.69cft
ii). For plinth beam – 36.412cft
Total volume of backfilling – 48.69 + 36.412 = 85.102cft or 2.409cum.
ESTIMATE OF BOUNDARY WALL
Total Concrete Volume – Footing + Plinth beam + Column
= 0.743 + 2.675 + 1.561 = 4.979m³ or 175.83Cft
For M20 Concrete Grade –
Cement Required – 40Bags
Sand Required – 2.091m³ or 73.85Cft
Aggregates Required – 4.182m³ or 147.68Cft
Total Materials qty required for compound walls
i). Total no. of cement required – Pcc + Masonary + RCC + Coping
= 12.70 + 12 + 40 + 3.537 = 68.237Bags
ii). Total volume of Sand required – Pcc + Masonary + RCC + Coping
= 31.22 + 88.99 + 73.85 + 8.675 = 202.735Cft
iii). Total volume of Aggregates required – Pcc + Masonary + RCC + Coping
= 62.30 + 147.68 + 17.35 = 227.33Cft
iv). Total steel required – Footing + plinth beam + column
= 43.98 + 260.69 + 175.9 = 480.57kg
v). Boulder for soling – 42Cft
vi). Bricks – 4794Nos.
