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 –**
Floor tile for the room, Floor tile for the bathroom, wall tile for the bathroom.

· **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 = 6.22m ^{3}**

^{ }

**Nos. of Bricks, Cement and Sand Quantity
and Costing**

**THUMB RULE:**

**No of brick per 1m ^{3 }=
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/m ^{3}**

^{}

**Cost of cement bags = 400/bag**

**Sand per cum (1:5) = 0.271cum/m ^{3}**

^{}

**Cost of sand (cft) = 45/cft = 1589.16/m ^{3}**

^{ }

**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 m^{3}

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 m^{3}

**We
know the density of steel = 7850 kg / m ^{3}**

So, we can calculate the weight of steel in kg.

Weight of steel = 0.049 m^{3} x 7850 kg/m^{3}

**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/m ^{3}**

^{}

**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/m ^{3}**

**Therefore, ****for
271.233 sqm Mortar = 271.33 x 0.015 = 4.05 – 5m ^{3}**

^{}

**Cost of P-sand (cft) = 85/cft = 3000/m ^{3}**

^{}

**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**

**ALSO READ: HOW
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 (**Also use: **Tile Calculator | Estimate Many Tile You Need | Skirting Calculator )

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)
