Brick calculation Thumb rule :
Thumb Rules are made on experience basis that gives the approximately results. It is essential for any civil engineer, Site engineer, or civil supervisor. It help in a crucial role while taking quick decisions on construction site. There is some civil engineering basic knowledge that every civil engineer and site engineer must know.
Thumb rule for brick calculation helps you finding out the solution by using a simple mathematical formula and make a smart decision whenever needed. It does not tells about accurate or exact number of of bricks, it gives approximately result. By knowing the Thumb Rule, it help you in calculating the approximate number of bricks required at construction site for your building or house or room.
There are different types of brick wall are popularly used in construction are 4 inch thick brick wall also known as single brick or half wall made of single brick layer, 9 inch thick brick wall also known as double or full brick wall made of double brick layer. Bricks are varies in size, so 5 inch (single brick) and 10 inch (double brick) brick wall are also popular.
You are doing Brick calculatio in several different unit such as cubic meter (m3), cubic foot (ft3), square foot (sq ft or ft2) and square meter (sqm or m2). In this article we know about Thumb rule for brick calculation in 4″, 5″, 9″, 10″, 6″ and 8″ brick wall.
Thumb rule for brick calculation:
When you are think about starting and new projects of brick masonry brick in external and internal or partition wall in the house, boundaries for Garden, retaining wall, brick pier, foundation and columns.
One of the toughest aspect is determining how many bricks you will need, ordering few bricks make delay in construction for over ordering make loss of money that increases your estimate for construction, so thumb rule for brick calculation for wall and its formula help you and better guide to calculate number of bricks in a wall.
Thumb rule for brick calculation per sqm:
1) Using thumb rule for brick calculation in square metre for half brick or singular layer or 4″ brick wall, multiply the length of brick masonry wall by the height to get area measured in square meter, then multiply that area by 50 to get the number of bricks you needed. Then add @10% extra for wastage and breakage during transportation storage and brick wall installation
Thus, thumb rule formula:- No. of bricks in 4″ (single brick, half brick wall) wall per m2 = (Area in sqm × 50) + @10% extra.
For example:- a brick wall of 5 meter in length and in 3 meter height made of 4″ thickness or single brick, half brick wall, then calculation No. of bricks you needed. Ans. Multiply the length and height = 5m ×3m = 15m2, you get 15 square meter area, multiply the area with 50 = 15×50 = 750 nos, thus you will need approximately 750 nos bricks for this brick wall.
2) Using thumb rule for brick calculation in square metre for full brick or double layer or 9″ brick wall, multiply the length of brick masonry wall by the height to get area measured in square meter, then multiply that area by 100 to get the number of bricks you needed. Then add @10% extra for wastage and breakage during transportation storage and brick wall installation
Thus, thumb rule formula:- No. of bricks in 9″ (double brick, full brick wall) wall per m2 = (Area in sqm × 100) + @10% extra.
For example:- a brick wall of 5 meter in length and in 3 meter height made of 9″ thickness or double brick, full brick wall, then calculation No. of bricks you needed. Ans. Multiply the length and height = 5m ×3m = 15m2, you get 15 square meter area, multiply the area with 100 = 15× 100 = 1500 nos, thus you will need approximetely 1500 nos bricks for this brick wall.
Thumb rule for brick calculation per sq ft:
1) Using thumb rule for brick calculation in square foot for half brick or singular layer or 4″ brick wall, multiply the length of brick masonry wall by the height to get area measured in square feet, then multiply that area by 4.5 to get the number of bricks you needed. Then add @10% extra for wastage and breakage during transportation storage and brick wall installation
Thus, thumb rule formula:- No. of bricks in 4″ (single brick, half brick wall) wall per sq ft = (Area in sq ft × 4.5) + @10% extra.
For example:- a brick wall of 15 feet in length and in 10 feet height made of 4″ thickness or single brick, half brick wall, then calculation No. of bricks you needed. Ans. Multiply the length and height = 15 ft ×10 ft = 150 ft2, you get 150 square feet area, multiply the area with 4.5 = 150×4.5 = 675 nos, thus you will need approximately 675 nos bricks for this brick wall.
2) Using thumb rule for brick calculation in square foot for full brick or double layer or 9″ brick wall, multiply the length of brick masonry wall by the height to get area measured in square feet, then multiply that area by 9 to get the number of bricks you needed. Then add @10% extra for wastage and breakage during transportation storage and brick wall installation
Thus, thumb rule formula:- No. of bricks in 9″ (double brick, full brick wall) wall per sq ft = (Area in sqm × 9) + @10% extra.
For example:- a brick wall of 15 feet in length and in 10 feet height made of 9″ thickness or double brick, full brick wall, then calculation No. of bricks you needed. Ans. Multiply the length and height = 15 ft ×10 ft = 150 ft2, you get 150 square feet area, multiply the area with 9 = 150× 9 = 1350 nos, thus you will need approximately 1350 nos bricks for this brick wall.
Thumb rule for brick calculation per m3:
Using thumb rule for brick calculation in cubic meter (m3) for 9″ (full brick or double layer) brick wall or 4″ (single brick, half brick) brick wall, first convert all dimension length height and thickness in meter then multiply the length of brick masonry wall by the height and to the thickness to get volume measured in cubic meter, then multiply that volume by 500 to get the number of bricks you needed.
Thus, thumb rule formula:- No. of bricks in 9″ (double brick, full brick wall) or 4″ (single brick, half brick) wall per m3 = volume in m3 × 500
For example:- a brick wall of 5m in length and in 3m in height made of 230mm in thickness or double brick, full brick wall, then calculation No. of bricks you needed. Ans. Multiply the length, height and thickness = 5m ×3m ×0.23m = 3.45, you get 3.45 cubic meter volume, multiply the volume with 500 = 3.45× 500 = 1725 nos, thus you will need approximately 1725 nos bricks for this brick wall.
Thumb rule for brick calculation per cu. ft:
Using thumb rule for brick calculation in cubic foot (cft) for 9″ (full brick or double layer) brick wall or 4″ (single brick, half brick) brick wall, first convert all dimension length height and thickness in feet then multiply the length of brick masonry wall by the height and to the thickness to get volume measured in cubic feet, then multiply that volume by 13.5 to get the number of bricks you needed.
Thus, thumb rule formula:- No. of bricks in 9″ (double brick, full brick wall) or 4″ (single brick, half brick) wall per cu. ft = volume in cu. ft × 13.5
For example:- a brick wall of 15 feet in length and in 10 feet in height made of 9″ in thickness or double brick, full brick wall, then calculation No. of bricks you needed. Ans. Multiply the length, height and thickness = 15 ft×10 ft× 0.75 ft = 112.5 ft3, you get 112.5 cubic feet volume, multiply the volume with 13.5 = 112.5× 13.5 = 1520 nos, thus you will need approximately 1520 nos bricks for this brick wall.
Conclusions:
Thumb rule for brick calculation:- 1) No. of bricks in 4″ wall per m2 = Area in sqm × 50, 2) No. of bricks in 9″ wall per m2 = Area in sqm × 100, 3) No. of bricks in 4″ wall per sq ft = Area in sq ft × 4.5, 4) No. of bricks in 9″ wall per sq ft = Area in sq ft × 9, 5) No. of bricks per cubic foot (cu ft) = volume in cu ft × 13.5, 6) No. of bricks per cubic meter (m3) = volume in m3 × 500.
