Introduction of Rate Analysis of Brick Masonry
Important Point
Rate analysis of brick masonry used of reference book IS Code 1200 part 3(IS Code 1200 part 3 used for measurement), IS Code 2212, and CPWD Part 1.
All calculations of brick masonry for rate analysis. This calculation calculates of brick and mortar (mortar = Cement + Sand past this call mortar) for materials.
Mortar is used a sum different proportions 1:2, 1:4, 1:6, 1:8, etc.(1 cement: 2 Sand). This quantity estimation of bricks is required for the rate analysis.

Important Point in Rate Analysis of Brick Masonry
Measurement of Brick Masonry
In booking dimensions, the order will be consistent and generally at the sequence of length, breadth or width and height or depth or thickness.
Brickwork shall be measured in cubic meters unless otherwise specified.
Any extra work over the specified dimensions will be ignored.
Dimensions will be measured correct to the nearest 0.01 m, i.e., 1 cm. Areas will be calculated to the nearest 0.01 sq meters, and the cubic contents shall be worked out to the nearest 0.01 cubic meters
Brickwork will be measured separately in the following stages:
- From foundation to floor one level (Plinth level)
- Plinth (floor one) level to floor two-level
- Between both specified floor levels above floor two-level
Dednctioan of Brick Masonry
Where a minimum area is defined for deduction of an opening, void, or both, such area shall refer only to opening or void within the space measured.
Where a minimum area is defined for deduction of an opening, void, or both, such areas shall refer only to opening or void within the space measured.
Ends of dissimilar materials (that is, joists, lintels, beams, rafters, posts, girders, purlins, corbels, trusses, steps, etc.); up to 0.1 m2 in section;
Opening up to 0.1 m2 in area
Wallplates, bed plates and bearing of slabs, chajjas and the like, where thickness does not exceed 10 cm and the bearing does not extend over the full thickness of the wall;
Cement concrete blocks as for holdfasts and holding down bolts;
Iron fixtures, such as wall ties, pipes up to 300 mm diameter and holdfasts for doors and windows; and
Chases of section not exceeding 50 c.m. in girth.

Dimensions of Brick Masonry
The brick can be modular or non-modular.
Sizes for two types of bricks/tiles shall be as per the below table.
While the use of modular bricks/tiles is recommended, non-modular (FPS) bricks/tiles may also be used where so specified.
Non-modular bricks/tiles of sizes other than these sizes mentioned below table may also be used where specified.

Calculation of Brick for Rate Analysis of Brick Masonry
Size of actual brick dimensions of 190 mm x 90 mm x 90 mm
The volume of 1 brick with mortar = 200 x 100 x 100 ( 10 mm mortar thickness on all sides)
= 0.2 m x 0.1 m x 0.1 m
The volume of a brick with mortar = 0.002 Cum (m3)
Therefore, Number of bricks required for 1 Cum (m3) = 1/0.002 = 500 Nos.
Requirement of brick 10 cu.m. = 500 nos (1 cu.m = 500 nos. of brick) x 10 cu.m
So, 10 cu.m. brick work requirement of brick = 5000 nos. of brick requirement

Cement and Sand Calculation
Calculation of Cement
The volume of bricks without mortar
Volume of 1 brick without mortar = 190 mm x 90 mm x 90 mm
- = 0.19 m x 0.09 m x 0.09 m
The volume of 1 brick without mortar = 0.001539 Cu.m. (m3)
The volume of 500 bricks without mortar = 500 nos. X 0.001539 Cu.m. (m3)
The volume of bricks without mortar for 1 cum = 0.7695 Cu.m. (m3)
So, The required amount of cement mortar = 1 Cum – Volume of bricks without mortar
- Cement Mortar = 1 Cu.m. (m3) – 0.7695 Cu.m. (m3)
Required amount of cement mortar Required amount of cement mortar = 0.2305 Cu.m.(m3) (Wet Condition) = 0.2305 Cu.m. (m3)
Convert Dry volume of a mortar = 0.2305 Cu.m. x 1.33 = 0.306565 Cu.m.
Cement mortar ratio is 1:3 (1 cement : 3 fine sand)
The required amount of Cement quantity at brickwork = 0.306565 Cu.m. x (1/(1+3))
- = 0.306 x 0.25
- = 0.07664125 cu.m. cement requirement
- Cement in k.g. = volume x density cement
- Cement in k.g. = 0.07664125 cu.m. x 1440 (1440 kg/m Density of cement for 50 k.g)
- = 0.07664125 x 1440 = 110. 363 kg of cement of bag requied ment of cement in k.g.
- = 110.363 / 50 (one cemnent bag weight 50 k.g. only) = 2.20 bag
- So, 10 cu.m. brick work requirement of cement = 2.20 bag x 10 cu.m. = 22 bag
Calculation of Sand
Required amount of Sand = 0.306565 x 3/(1+3)
- =0.2299 Cu.m. requierd of sand for 1 Cu.m.
So,
- So, 10 cu.m. brickwork requirement of sand = 0.2299 Cu.m x 10 cu.m. = 2.299 cu.m.

Brick Work Rate
On average, a new brick wall or fence costs $5,000, but prices nationwide range from $2,410 to $8,050. The cost of materials is about $10 to $45 per square foot, and the labor rate is somewhere around $60 to $105 per hour.

Is Code for Brick Masonry?
IS: 2212 – 1991. Code of Practice for brickwork (IS: 2212 – 1991) deals with the construction of clay brick masonry in general and the erection of clay brick walls in particular.
Labour Rate for Brick Work
Generally, the Rate of Brickwork varies from 6000 to 8000 INR per Cubic Meter for superstructures.
Brick Work Rate Per Cubic Meter
Brick Work Labour Rate Per m
Total Labour Cost for Brickwork, as calculated from the above example is 1578 INR, which is 1578/6957=22% of the total project cost. The Brick Work Labour Rate Per m3 is 1500-1800 INR depending on the availability of labour and the location.
Brickwork Labour Rate
In many countries, labor rates are usually quoted on a daily basis. The daily labor rate for brickwork can range anywhere from $80 to $150 or more, depending on the factors mentioned above. It’s important to note that these rates are approximate and can vary significantly from one region to another.
Brick Rate
The rate of bricks can vary based on factors such as the type of brick, quality, location, and market conditions. Concrete bricks, also known as concrete blocks or cinder blocks, are another popular choice. The rates for concrete bricks can range from $0.50 to $1.50 per brick, depending on the size and design.

BBM stands for Brick/Block Masonry (saw)
Non Modular Brick Size
The size of non-modular brick size is 230 x 110 x 70 mm or 230 x 110 x 30 (length x depth x height). Additionally, for obtaining proper bond arrangement and modular dimensions for the brick work, with the non-modular sizes, the sizes of bricks may be 70 x 110 x 70 mm (length x depth x height).
Brick Masonry Rate Per Square Foot
On average, brick masonry rates can range from $10 to $30 per square foot. This typically includes the labor and materials required for the installation. However, keep in mind that this range can be higher for more complex projects or if you’re using higher-end bricks.
Labour Cost for Brickwork
The labor cost to build a brick wall is $40 to $100 per hour. Brick masonry labor rates are $7 to $17 per square foot on average. The total labor charge for brickwork depends on the wall thickness, location, wall design, supplies needed, and the mason’s skill level.
Brick Work Ratio
The standard ratio for average mortar mix is 3:1 or 4:1 for bricklaying. If you are using a pointing mix, then you should have a ratio of 1:4 or 1:5 mortar to sand.
Size Stone Masonry Rate Analysis
The rate for stone masonry can also vary depending on several factors, such as the type of stone used, the size of the stones, the complexity of the project, the location, and the skill level of the mason. Random rubble masonry refers to stones of irregular sizes and shapes fitted together. The rate for random rubble masonry can range from $25 to $60 per square foot.
Block Work Rate Per M2
the rate for block work can range from $20 to $40 per square meter. However, keep in mind that this range can be higher for more complex projects or if specialized blocks are required.
