📐 QUANTITY SURVEYING TIP: HOW TO CALCULATE WALL AREA
Wall area calculations are commonly used when estimating plastering, painting, tiling, and other finishing works.
🔹 Formula
Wall Area = Length × Height
🏗️ Example
A wall has:
Length = 6 m
Height = 3 m
Area = 6 × 3
Gross wall area = 18 m²
🔹 What About Doors and Windows?
Suppose the wall contains:
One door: 2.1 m × 0.9 m = 1.89 m².
One window: 1.2 m × 1.0 m = 1.20 m².
Total opening area = 1.89 + 1.20 = 3.09 m².
Net wall area = 18 − 3.09
Net wall area = 14.91 m²
📌 This is a simplified calculation. Actual BOQ measurement rules may specify whether openings, reveals, deductions, and other details are included.
🧠 Practice: A wall is 8 m long and 3.2 m high. What is its gross area?
