Material and labour Cost of One Room Construction | Material and labour Cost of room with attached bathroom Construction | Cost to Build 10×10 Room in India | Room Estimation |10X15 room Construction Cost in India
In this article, we will explain how to calculate what is the construction cost of 10 x 15 room with an attached bathroom and its materials
estimate.
Whenever
someone decides to build a house or room, he or she will want to make sure he
knows the cost of the construction before assigning or starting it. This is
essential to know the approximate construction cost before starting
construction. This is also called estimation. Estimation of work is done to
know financial backup check and comparison on contractor quote
10 x 15 ROOM WITH
ATTACHED BATHROOM
In this article, we will
explain how to calculate the cost of construction and material quantities for this
material.
List of quantities and cost to be calculated,
· Brick Work –
quantity of Brick, the quantity of Cement, the quantity of Sand in Mortar.
· Concrete Work –
Concrete quantity in column, beam, and slab.
· Steel Reinforcement – no
of bars and its cost quantity.
· Plastering
· Painting
· Tile –

· Sanitary fittings –
Toilet (W.S), Tap – 2 nos, shower, wash
basin
· Electrical – Switch
board – 2 nos, Roof piping
· Plumbing material
· Labour Work and Cost
Before going to start you need to know the basics
conversation as follows.
3.28
ft = 1 m |1 m = 3.28 ft
1
ft = 12 inch | 12 inch = 1 ft
To
convert ft to meter divide ft value by 3.28
EX:
value is 15 ft then the (15/3.28) = 4.57 m.
Similarly, to
convert inch to meter multiple inch value with 0.0254
EX:
Value is 4” then (4 x 0.0254) = 0.10 m (100 mm).
Let’s calculated each quantity one by once,
Brick Work – Quantity Of Brick, Quantity Of
Cement, Quantity Of Sand In Mortar.
Brick walls are classified into two which are interior
and exterior brickwork.
Exterior
brickwork = 9 inch (230mm)
Interior
brickwork = 4.5 inch (115mm)
Parapet
Wall (brickwork above the slab as parapet wall) = 4.5 inches (115mm)
Brick Work Quantity
Calculation
Total Brickwork = Total
Brick Work – Deductions (Windows And Door)
Total Brickwork = 6.22m3
Nos. of Bricks, Cement and Sand Quantity
and Costing
THUMB RULE:
No of brick per 1m3 =
500nos
Cost of brickwork = 8/nos
(Cement: Sand) = (1:5)
M-Sand, (1:4) River Sand
We will take (1:5) M-Sand
Cement bag per cum (1:5) =
1.55bags/m3
Cost of cement bags = 400/bag
Sand per cum (1:5) = 0.271cum/m3
Cost of sand (cft) = 45/cft = 1589.16/m3
Brick for 6.22m3 = 6.22 x
500 = 3110nos
Cement bag for = 6.22 x
1.55 = 9.64 = 10bags
Sand per cum (1:5) =
6.22 x 0.271 =1.68cum
Total Cost Brick
Work: Rs. 31426
Concrete Quantity In
Column, Beam And Slab
Size
of column = 9″ x 9″ (0.23 m x 0.23 m)
Size of beam = 9″ x 16″ (0.23 m x 0.40 m)
Slab,
Length = 10’ / 3.50 m
Width = 15’ / 4.57 m
Thickness = 5”/ 125mm
Therefore, beam depth reduced into 16”-5” = 11”
Size
of beam = 9″ x 11″ (0.23 m x 0.279 m)
Total Concrete Volume = 3.29 m3
Ready mix concrete (RMC) cost for M-25 Grade of Concrete
= 4500 Rs./CUM
Cost of Concrete = 3.29 x 4500 = Rs 14820
Total Cost of
Concrete = Rs. 14,820
Reinforcement (Steel)
Quantity And Cost
Generally, the amount of
steel in column, beam and slab reinforcement is considered to be 1% to 2% of
the concrete volume.
We will take,
Volume of Reinforcement (Steel) = 1.5% of Volume of
Concrete
Volume of Reinforcement (Steel) = 0.015 x 3.29 = 0.049 m3
We
know the density of steel = 7850 kg / m3
So, we can calculate the weight of steel in kg.
Weight of steel = 0.049 m3 x 7850 kg/m3
Weight
of steel = 384.65 kg
As per the market rate of construction, steel is about 58 to
68 Rs. per Kg in the market.
So, if we will take 60 Rs. / kg rate
Therefore,
Cost of Steel = Weight of Steel x Rate of Steel
= 384.65 x 60
Total Cost of Steel
= Rs. 23,079
Plastering Quantity And
Cost
In Plastering Wall Has two sides
EXAMPLE:
Exterior Plastering = 9 inch (230mm) (shorter span -
10ft)
It has two wall of four sides (interior & exterior)
Therefore,
= 4 sides x 3.05 x 2.74 = 33.428sqm
Total 12mm thick Plastering in Cm 1:4 = 141sqm
Cement bag per
cum (1:4) = 0.11 bags/m3
Therefore, for
271.233 sqm Mortar = 271.33 x 0.11 = 29.8 – 30 bags
Cost of cement bags = 400/bag
Total cost of cement bags = 30 x 400 = Rs 12000
Sand per cum
(1:5) = 0.015 cum/m3
Therefore, for
271.233 sqm Mortar = 271.33 x 0.015 = 4.05 – 5m3
Cost of P-sand (cft) = 85/cft = 3000/m3
Total cost of cement bags = 5 x 3000 = Rs 15000
Plastering Quantity and Cost = 12000 + 15000 = 27000
Total cost of
Plastering Quantity = 27000rs
Painting Quantity And
Cost
Painting quantity
= plastering quantity
Painting
quantity = 271.33 sqm

MUCH PAINTING MATERIAL DO I NEED?
Painting
material
1 sqm = 0.77 kg putty
1 sqm = 0.111 liter primer
1 sqm = 0.167 liter paint
Therefore,
Painting
quantity = 271.33 sqm
Putty =
271.33 x 0.77 = 208.5 – 210kg
Cost of 1 putty bag 850/bag
So we need three bags of putty which cost 850 x 3 =
2550rs
Primer
=
271.33 x 0.111 = 30.11 – 31liter
The cost of 1-litre primer varies from 150 to 500/litre. We
will take 200/litre
So we need 31 litres of primer which cost 200 x 31 =
6200rs
Paint
=
271.33 x 0.167 = 45.31 – 46liter (Two Coat)
The cost of 1 litre of paint varies from 150 to 500/litre. We
will take 280/litre
So we need 31 litre of paint which cost 280 x 46 = 12880rs
Total
Cost Of Painting Material = 2500 + 6200 + 12880 = 21580
The total cost of Paint Quantity
= 21580rs
Tile Quantity And Cost
Tile rate varies from 25 to 200rs/tile. We will take 45rs/tile
Therefore,
= 377tiles x 45 = 16965rs
Total cost of Tile Quantity
= 16965rs
Sanitary Fittings And
Cost
Total cost of Sanitary
fittings = 15000rs
Electrical |
Plumbing Quantity And Cost
We need 3 switch board for room
In,
Near door
Backside of TV
Near bedside
And 1 switchboard in the bathroom
1 switchboard cost will 1500 – 4000/switchboard ( N/A)
– we will take 2000/board (includes – switch, socket, roof pipe, casing pipe,
wire)
Therefore, for 3 switch board = 3 x 2000 = 6000
1 water point cost will 1000 – 3000/point ( N/A) – we
will take 2000/board
Therefore, for 3 switchboard = 2 x 2000 = 4000
Total cost of
Electrical | Plumbing = 10000rs
Door | Window
Quantity And Cost
Door rate = 1800 -10000rs
we will take 2500rs/door
Aluminium window (3x4)
= 360 – 600rs/sqft =we will take 360rs/sqft so 12 x 360 = 4320rs/window
Total cost of Door |
Window = 6820rs
TOTAL COST OF MATERIALS
Cost Brick Work: Rs. 31,426
Cost Of Concrete = Rs. 14,820
Cost Of Steel = Rs. 23,079
Cost Of Plastering Quantity = Rs. 27,000
Cost Of Paint Quantity = Rs. 21,580
Cost Of Tile Quantity = Rs. 16,965 (
Cost Of Sanitary Fittings = Rs. 15,000
Cost Of Electrical | Plumbing = Rs. 10,000
cost of Door | Window = Rs. 6820
TOTAL
COST OF MATERIALS = 31,426+14,820+23,079+270,00+21,580+16,965+15,000+10,000+6820
TOTAL COST OF MATERIALS =
Rs 166690
TOTAL COST OF LABOURERS
Total area = 10 x 15 = 150sqft
Cost of construction
works = 365/sqft – 450/sqft
Therefore, 365 x 150 = 54750rs
Cost of Electrical works
= 25/sqft – 40/sqft
Therefore, 35 x 150 = 5250rs
Cost of Plumbing works
= 15/sqft – 30/sqft
Therefore, 20 x 150 = 3000rs
Cost of carpenter works
= 900/labour
Therefore, we may need 2 labour to fix door and window so 900x2 =1800rs
TOTAL COST OF LABOURERS = 54750+5250+3000+1800 = 64800
TOTAL COST OF LABOURERS =
Rs 64800
FINALLY,
Cost Of 10 X 15 Room With
Attached Bathroom Construction = Total Cost Of Materials (Rs
166690) + Total Cost Of Labourers (Rs 64800) = 231490
Cost Of 10 X 15 Room With
Attached Bathroom Construction = Rs 231490
NOTE: all this cost of material and labour
varies from place to place and time to time (this rate quoted 28/06/21 – corona
period)
