Introduction of Rate Analysis of Brick Masonry

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.

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.
  • I am bearing a portion of the drip course, bearing of molding and cornice.

Dimensions of Brick Masonry

Her, the steps of dimensions of brick masonry mesurmant

  • 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.

Masonry Labor

A masonry worker uses concrete, concrete blocks, bricks, and manmade or natural stone to build fences, walls, walkways, and other masonry structures. They lift heavy materials and must bend, stand, and kneel for long periods of time and the work is physically demanding.
