How to Calculate Quantity of Bricks in Building

Written by: Engr Sami Ullah Stanikzai (www.civilglobal.com)

In this Article I will show You that how we can find out the quantity of bricks in building in detail.After reading this article you will be able to find out the quantity of bricks in any construction work. lets get start.Here we have take the given size for the brick.

  • The size of the modular brick is 190 X 90 X 90 (refer the picture)
  • Mortar Thickness is 10mm but here i dont count the mortar just find out the bricks quantiyt without the mortar in next lecture it will be with moirtar.
  • Any brick walls consist of bricks and cement mortar.

So, first of all, we are going to find the volume of bricks with mortar thickness and then volume of bricks alone.

 

Note: In this Method I you are able to learn the short Wall and long Wall method for Bricks calculation in building.

Image is taken from my You Tube Channel : Civil Engineers

Given Data for long wall and short wall.

Length of long wall = 3.5+3.5+0.30+0.30×2 = 15.2m

Length of short wall = 3×4.30 = 12.9m

Total length of wall = 28.1m

Now in 2nd step i will  calculated deduction of Windows, Doors and Ventilators.

Doors = 2.1×1.05×0.30(2) = 1.32 cum

Windows = 1.2×1.2×0.30(2) = 0.86 cum

Door Volume  = 1.5×0.45×0.30(2) = 0.28 cum

Window Volume = 1.20×0.45×0.30(2) = 0.32 cum

Therefore we have total Decturetion quantity in meter cube (M3)

= 2.78 cum

So Now from total volume of short wall and long walls we have to subrratcr the dectuoin volume for window and ventilatoer which volume is 2.78 cum.

When we deduct the window , door and ventilators volume from the total volume for long – wall and short – wall than it will give us the actual volume to find out the quantity for bricks in above 2 (Two) Rooms building quantity.

So,,

Total volume for Bricks Calculation = Total volume of Long wall and short Wall – Deduction volume

when the actual volume become from this this calculation.

than Used this formula to find out the Quantity for Bricks in building.

No’s of Bricks = Total volume of Walls / Volume of Brick = No’s of Bricks

The Size of the bricks can be change for different countries.

Therefore you are able to use those size for bricks which are using in  that place.

important points before starting bricks quantity.

1: The Mortar thickness should not be more than 10 mm between the courses and sides of the bricks it should be less but not more than 10mm.

2: We have to use the good quality of cement and sand for bricks masonry.

3: The Cement mortar ratio should be 1:6 for 9” Brickwork and 1:4 41/2” brickwork, than it will give us good strength.

Note: But in this method it will give you the bricks quantity without the mortar volume . And i will try to write the next article that how to find out the quantity for mortar in brick works or in wall.

The is the actual formulas to find out he volume of walls and bricks. So you are able to use the same formula at the site for quantity of bricks in any construction works.
