Construction Cost Estimating


Some useful tips to compute the number of bricks

Brick Calculator: Ability to work out the number of bricks in your wall is a vital factor while going to create plan for your project. The cost of even the most common bricks may be very costly, specifically when you opt for so called “Hand Made” bricks. “Specials” bricks which are utilized for things like window cills, window head detailing and architectural strings of bricks will also become expensive.

How to calculate the numbers of bricks

While going to calculate the number of bricks, consideration should be given on the following points :-

• Density of the wall to be constructed
• Amount of openings
• Amount of detail in the wall ie: Decorative panels, Dentilation or Dogtooth String Courses

The density of the wall is considered to be the most vital factor. Standard facing brick is mostly recognized in brick wall construction. The standard size brick is generally available as 215mm x 102.5mm x 65 mm, along with the use of a 10 mm mortar joints that run both horizontally and vertically.

The rule of thumb for calculating the number of bricks is to measure the total area of your building to be clad with brickwork for each existing square meter.

You have to multiply this by 60. Suppose, there is a wall having length 6 metres and height 2 metres, the square area will be 12 m. Therefore, total numbers of bricks will be 720.

There is 10% wastage because of transportation or just delivering the bricks around your project, some bricks are quite fragile:

Single Skin Wall
• 6m x 2m = 12 square metres x 60 (number of bricks in a square metre) = 720 + 10% wastage = 792 bricks are needed

Double Skin Wall
• 6m x 2m = 12metres x 120 = 1440+ 20% wastage = 1728 bricks

Note: On the double skin wall, wastage is reduced

Blockwork Calculator: Block is a standard size that is now extensively used and it’s dimension is 440 x 215 x 100mm along with 10 mm joints. One will require 10 blocks per square metre, so the above dimensions should be used to get the same total.

• 6m x 2m = 12m x 10 blocks = 120 blocks
