Rate analysis of brickwork masonry is done to estimate the number of different materials like bricks, cement, and sand and the number of labour required for required work. Here I have explained a numerical and a video at the last of this article.

## Numerical Example

Q) Calculate the quantity of dry materials and labor cost for first-class brick in the superstructure in cement mortar 1:4 in 10 cu. meter

The following rates may apply at the site for different materials,

Sand = Rs.500 per cu. Meter

Cement = Rs. 370 per Bags

Standard Bricks = Rs. 8 per piece

First Class mason = Rs. 600 per Day

Man Mazdoor = Rs.400 per day

Woman mazdoor/Bhisti = Rs.350 per day

Solution:-

Given,

Volume of Brickwork = 10 m. cube

Volume 1 Brick = 90 x 90 x 190 mm

= 0.90 x 0.90 x 0.190 = 0.001539 m. cube

Assume, Thickness of the mortar = 10 mm

1) Volume of 1 brick with Mortar,

= 0.100 x 0.100 x 0.200 = 0.002 m cube.

2) No. of bricks with mortar = 10/0.002 = 5000 No.

3) Now, Volume 5000 Bricks without mortar = 5000 x 0.001539 = 7.695 m cube.

So,

4) Volume of mortar remained = 10 – 7.695

= 2.305 m cube.

5) Dry Volume of Mortar,

= 2.305 x 1.33 = 3.06 m cube.

Given, Cement : Sand = 1:4 (Sum = 5)

6) Quantity of Cement = (Ratio of Cement/ Sum) x Dry Volume

= 1/5 x 3.06 = 0.612 m cube.

So, Weight of Cement = Volume x density

= 0.612 x 1440 = 881.28 Kg. (1440 is the density of cement)

= 881.28/50 = 17.62 Bags of Cement

7) Quantity of Sand = (Ratio of Sand/ Sum) x Dry Volume

= 4/5 x 3.06 = 2.448 m cube.

8) No. of Labour Calculation

For, Brickwork per 100 cu. Feet (2.83 cum), 2.5 Mason, 4.5 Mazdoor, 0.5 Bhisti per day

2.5/x = 2.83/10

Or, x = 8.83 Mason

Lly,

4.5/x = 2.83/10

Or, x = 15.4 Mazdoor

Lly,

0.5/x = 2.83/10 or, x = 1.76 Bhisti

## Rate Analysis Table

Finally,

Rate per m. cum = 63379.94 / 10 = Rs. 6337.99/ cu. meter
