12. Building Calculations
Enumerated
Some building materials are measured by
the number (counted) such as chimney
pots, air bricks, doors and windows.
Linear
Other building materials are measured by
the length. Brick-on-edge is measured in a
linear measurement and not area.

13. Superficial
Length and height are multiplied to achieve the
superficial area of the material required.
The length of a wall is multiplied by the height to give
the square area of brickwork required.
Cubic Measurements
Cubic measurements are taken when there are
three dimensions.
Length, width and height of a foundation would
give the volume of concrete required.
Building Calculations

14. Regardless of the bond used, the number of
bricks will remain the same.
The quantity of facings and common bricks may
change if the wall is not faced on both sides.
• Half brick wall = 60 bricks/m².
• One brick thick = 120 bricks/m².
• One and a half brick = 180 bricks/m².
• Two brick thick = 240 bricks/m².
Quantities of bricks

15. Example 1:
A one brick wall built in English bond is 6.00 m
long and 1.50 m high. Calculate the number of
bricks required.
Answer:
6.00 x 1.50 = 9.00 m²
9.00 m² x 120 = 1,080 bricks required

16. Example 2:
A wall 7.50 m long by 2.10 m high is to be
one and a half bricks thick in Flemish bond.
Calculate the number of bricks required to
build the wall.
Answer:
7.50 x 2.10 = 15.75 m²
15.75 m² x 180 = 2,835 bricks required

17. Example 3:
A half brick wall built in Stretcher bond is
8.00 m long x 1.20 m high, with a opening
0.9 x 0.6 m.
Calculate the number of bricks required.
Answer:
Overall area: 8.00 x 1.20 = 9.6 m²
Opening area: 0.9 x 0.6 = 0.54 m²
Wall area with area of opening deducted
= 9.6 – 0.54 = 9.06 m²
9.06 m² x 60 = 543.6 bricks = 544 bricks required
