The rate analysis of brickwork involves working out the cost of materials like brick, sand, and cement and the cost of labour. The cost of material, as well as labour charges, varies from place to place. The availability of material and labour also affects the rates. In this article, we will learn to calculate the cost of brick walls.

## Stepwise Calculation for Rate Analysis of Brickwork

Rate analysis is done to determine the probable cost of the work which is to be done. The Estimated cost helps in determining the capital requirement for the work. Rate Analysis of brickwork involved three Steps. First is determining the quantity of material like Bricks, Cement and Sand required. The Second Step is determining the rate and amount of labour required for brickwork.

### Calculation of Material for 1 cum of Brickmasonry

In Brick masonry, the material required is Cement, Sand and Bricks. The quantity of these materials is required to be known beforehand. The process of calculation of material for 1 cum of brick masonry involves determining the quantity of cement in bags, the quantity of sand in cum and the number of bricks required.

#### Calculation of Bricks for 1 cum of Brickmasonry

The number of bricks depends on the size of the brick available. As per Indian Standard, the modular bricks have a size of 19 cm x 9cm x 9cm. Non-Modular bricks are available in different sizes. The choice of a particular size also depends on the location. Some States in India use different sizes compared to others. The most commonly used Non-Modular Bricks are 230x110x70 mm. As the thickness of and beam is usually kept 230 mm in India. Thus 230 mm length brick is commonly used.

No matter, what the size of brick is, you can always calculate the total number of bricks required for 1 cum of Brick Masonry. In the example shown below, I have calculated the total number of Standard size bricks required for 1 cum of Brickwork.

- Standard Size of Bricks with Mortar = 20x10x10 cm (assuming 1 cm of mortar)
- Number of Bricks in 1 Cum of Brickwork = 1/(0.2*0.1*0.1) =500 Nos.
- You can also add approx 5% as wastage. Thus total bricks will be 500*1.05 = 525.
- Likewise you can calculate the total bricks of sizes 230x110x110 mm, 230x110x70 mm, 230x110x30 mm.

#### Calculation of Mortar for 1 cum of Brickmasonry

- The volume of 1 Brick without mortar = 0.19×0.09×0.09 =0.001539 (taking standard size brick as example)
- Volume of Bricks in 1 cum of Brickwork = 500x 0.001539 = 0.7695
- Volume of Mortar= 1-0.7695 = 0.2305 Cum
- Add 25% extra for Dry volume of a mortar = 0.2305 Cu.m. x 1.25 = 0.288125 Cu.m.
- Add 10% extra for wastage = 0.288125*1.10 =0.316 Cum
- For 10 cum of Brickwork, quantity of mortar = 3.16 cum
- Qantity of Cement and Sand for 10 Cum of Mortar is given below:-

Cement Mortar Ratio | Sum | Volume of Cement | No. of bags of Cement | Volume of Sand |

Cement Mortar 1:6 | 1+6 = 7 | =(1×3.16)/7= 0.45 cum | 0.45/0.0347 =12.97 | =(6×3.16)/7=2.71 cum |

Cement Mortar 1:5 | 1+5 = 6 | =(1×3.16)/6= 0.53 cum | 0.53/0.0347 =15.27 | =(5×3.16)/6=2.63 cum |

Cement Mortar 1:4 | 1+4 = 5 | =(1×3.16)/5= 0.63 cum | 0.63/0.0347 =18.16 | =(4×3.16)/5=2.53 cum |

Cement Mortar 1:3 | 1+3 = 4 | =(1×3.16)/4= 0.79 cum | 0.79/0.0347 =22.77 | =(3×3.16)/4=2.37 cum |

Cement Mortar 1:2 | 1+2 = 3 | =(1×3.16)/3= 1.05 cum | 1.05/0.0347 =30.26 | =(2×3.16)/3=2.11 cum |

Cement Mortar 1:1 | 1+1 = 2 | =(1×3.16)/2= 1.58 cum | 1.58/0.0347 =1.30 =45.53 | =(1×3.16)/2=1.58 cum |

### Calculation of Labour rate for Brickwork

**Brickwork Labour rate per cum for Brickwork** can be calculated by knowing the amount of work labor can do in a day. The day for labour is not 24 hours but the day term is referred to the working hours i.e. 8 hours. So 8 hours of work is counted as a day. The total labour requirement for 1 cum of brickwork is :

- 1 Mason can do 1.25 Cum of Brickwork in a day.
- For 1 cum of Brickwork, Mason required = 1/1.25 =0.8 Nos.
- If two Masons i.e. 1st Class and 2nd Class are engaged, the amount of Mason required = 0.8/2 = 0.4 per day

- 1 Coolie can do 0.7 Cum of Brickwork, for 1 cum of brickwork = 1/0.7 = 1.43 coolie will be required.
- 1 Bishti can do 5 cum of Brickwork in superstructure. For 1 cum of Brickwork, no. of Bhishti = 1/5 = 0.20
