Painting rate analysis with an easy example

To calculate painting rate analysis we have to separately calculate each material cost including white washing, Glue, color pigment, wall putty, primer & paint as well as labour cost and adding them together we can find out the rate for wall painting.

Given,

length of long wall = 7750mm = 7.5m

length of short wall =3000mm = 3m

width = 250mm = 0.25m

height = 3500mm = 3.5m

No. of walls to be painted = 5

Material rate analysis of white washing

Area of long wall = area of inner surface+area of outer surface+area of top surface

= (Length*height)+(Length*height)+(Length*width)

= (7.5*3.5)+(7.5*3.5)+(7.5*0.25) = 54.375 m^2

Total area of long wall = 54.375*2 = 108.75 m^2

Area of short wall = area of inner surface+area of outer surface+area of top surface

= (Length*height)+(Length*height)+(Length*width)

= (3*3.5)+(3*3.5)+(3*0.25) = 21.75 m^2

Total area of long wall = 21.75*3 = 65.25 m^2

Quantity

3.5kg/10m² lime with 0.12kg glue is required for 3 coat white washing

since, total area of the walls = 108.75+65.25 = 174 m^2

Lime quantity = 3.5/10 = X/174

X = 60.9 ~ 70 Kg

Glue quantity = 0.12/10 = X/174

= 2.088 ~ 2.1 Kg

color pigment quantity = lump sum

Cost

Rate assumption

Lime/kg =  ₹ 80

Glue/kg = ₹ 250

color pigment = ₹ 100 (Lump sum)

Amount

Lime = 70*80 = ₹ 5600

Glue = 2.1*250 = ₹ 525

color pigment = ₹ 100

Material rate analysis of wall putty, primer & paint

Painting rate analysis

Quantity

Wall putty required for double coat (1.3-1.4)m²/kg

Total area of the walls = 174 m^2

primer required (11-13)m²/litre

paint required (11-13)m²/litre

Wall putty quantity = 1/1.4 = X/174

X = 124.28 ~ 124.3 Kg

Primer quantity = 1/11 = X/174

X = 15.818 ~ 15.82 Litre

Paint quantity = 1/13= X/174

X = 13.38 ~ 13.4 Litre

Cost

Rate assumption

Wall putty/kg =  ₹ 30

Primer/litre = ₹ 50

Paint/litre = ₹ 100

Amount

Wall putty = 124.3*30 = ₹ 3729

Primer = 15.82*50 = ₹ 791

Paint = 13.4*100 = ₹ 1340

labour rate analysis

Labour Assumption

Assuming the painting work to be completed in one with quantity of 2 painter 6 labour and 1 water carrier.

Rate for men required

Painter = ₹ 1000

labour = ₹ 800

water carrier = ₹ 600

Amount

Mason = 2*1000 = ₹ 2000

labour = 6*800 = ₹ 4800

water carrier = 600*1 = ₹ 600

4T&P (tools & plants)Lump sum300
Total₹ 7100

Total Cost = 12185+7100 = ₹ 19285

Add 1.5% water charges of total cost = 289.275 ~ 290

Add 10% contractor profit = 1928.5 ~ 1930

Grand Total =19285+290+1930 = ₹ 21505

For 174 m^2 of wall painting cost = ₹ 21505

Rate for wall painting will be 21505/174 = ₹ 124/m^2
