Guide to Brick Calculation in Pakistan
Understanding Brick Sizes (Awwal Class)
In Pakistan, the standard "Awwal" (First Class) brick size is nominally 9" x 4.5" x 3". However, when calculating for a wall, you must account for the mortar thickness (typically 10mm or 0.5 inches). This "nominal" size helps in estimating the exact number of bricks per cubic foot.
Single vs. Double Bricks (9" vs 4.5" Walls)
The type of wall determines your material needs:
- 4.5 inch Wall (Single Brick): Usually used for potential non-load bearing partitions. Requires ~4.5-5 bricks per sq. ft.
- 9 inch Wall (Double Brick): Standard for load-bearing external walls. Requires ~9-10 bricks per sq. ft.
- 13.5 inch Wall: Used for foundations or heavy load-bearing structures.
Wastage and Cost Estimation
Bricks in Pakistan are often sold in thousands. Prices vary by region (e.g., Lahore vs Karachi) and quality (Awwal vs Doam). Always add 5% to 10% wastage to your calculation to account for breakage during transportation and unloading.
Frequently Asked Questions
For a 9-inch thick wall, you need approximately 57 bricks per square meter. For a 4.5-inch thick wall, you need about 28 bricks per square meter.
The standard brick size in Pakistan is 9 inches x 4.5 inches x 3 inches (225mm x 112.5mm x 75mm).
Yes, add 5-10% extra bricks to account for breakage, cutting, and wastage during construction.
For curved walls, calculate the area as you would for a straight wall using the average radius, then add 10-15% extra for cutting and wastage.
