rate analysis of simple brick work masonry

Rate analysis of brick involves calculation of material quantity like cement, sand & bricks and its cost as well as the cost of men required for brick work like mason, labour, water carrier, etc.,

rate analysis of brick work

Given,

length = 2500mm = 2.5m

width = 200mm = 0.2m

height = 3000mm = 3m

No. of walls to be brick worked = 4

mortar ratio = 1:4 (cement : sand)

mortar thickness = 10mm

material rate analysis

volume of each wall = 2.5*0.2*3 = 1.5m^3

standard size of brick = (190x90x90)cm

volume of one brick without mortar = 0.19*0.09*0.09 = 0.00154m^3

volume of one brick with mortar = 0.2*0.1*0.1 = 0.002m^3

No. of bricks with mortar = 1.5/0.002 = 750

volume of 750 bricks without mortar = 0.00154*750 = 1.155m^3

Quantity

volume of mortar in each wall = 1.5-1.155 = 0.385m^3

Dry volume of mortar = 1.33*0.385 = 0.512m^3

sum of ratio = 1+4 = 5

Cement Quantity = (1/5)*0.512*(1440/50) = 2.94 ~ 3 bags

Sand Quantity = (4/5)*0.512*35.32 = 14.467 ~ 14.5 cft

Brick Quantity = 750 nos.

Cost

Rate Assumption

cement/bag = ₹ 600

sand/cft = ₹ 15

brick/no. = ₹ 10

Amount

cement = 3*600 = ₹ 1800

sand = 14.5*15 = ₹ 217.5 ~ 218

bricks = 750*10 = ₹ 7500

labour rate analysis

Labour Assumption

First class brick work for 1:4 Cement mortar quantity of 2.5 Mason, 4.5 labour, 0.5 water carrier can do (100 cft) 2.83m³/day

Men required for the work

since, volume of each wall = 1.5m^3

Total brick work volume = 1.5*4 = 6m^3

Mason required = 2.5/X = 2.83/6

X = 5.3 ~ 6

Labour required = 4.5/X = 2.83/6

X = 9.54 ~ 10

water carrier = 0.5/X = 2.83/6

X = 1.06 ~ 1

Rate for men required

Mason = ₹ 1000

labour = ₹ 700

water carrier = ₹ 500

Amount

Mason = 1000*6 = ₹ 6000

labour = 700*10 = ₹ 7000

water carrier = 500*1 = ₹ 500

Labour cost table

2labour1017007000
3water carrier11500500
4T&P (tools & plants)
Total₹ 13500

Total Cost = 38070+13500 = ₹ 51570

Add 1.5% water charges of total cost = 773.55 ~ 774

Add 10% contractor profit = 5157

Grand Total = 51570+774+5157 = ₹ 57501

For 6m^3 of brick work masonry = ₹ 57501

Rate for brick work masonry will be 57501/6 = ₹ 9584/m^3
