Quantity Surveying – When is brickwork NOT measured in cubic metres? In civil engineering measurement (IS 1200 practice), brickwork items are generally measured by volume (cubic metres). Identify the case where brickwork is measured by area instead, and therefore should NOT be taken in cubic metres.

Introduction / Context:
Accurate quantity take-off depends on using the correct unit of measurement for each item. In building works, brick masonry is usually measured in cubic metres because it is a volumetric work. However, some thin or special configurations are measured differently to align with how the work is executed and paid in practice.

Given Data / Assumptions:

• Standard measurement practice as per common schedules and IS-style conventions.
• Brickwork thickness categories: half-brick (about 115 mm), one-brick (about 230 mm), and thicker.
• Arches and reinforced brickwork are still masonry items requiring volume-based assessment unless specified otherwise.

Concept / Approach:

Conventionally, full-thickness brick masonry is measured in cubic metres because both thickness and height are significant and vary. For thin partitions (about half-brick), the work is practically planar and best captured by area measurement (square metres), with thickness stated separately. This reflects site practice and provides clearer rate analysis (including bond, stiffeners, and support details).

Step-by-Step Solution:

Verification / Alternative check:

Check standard Bill of Quantities: half-brick partition lines appear with m^2 units, thickness noted; full-thickness walls appear in m^3 with deductions and additions for openings/bond beams.

Why Other Options Are Wrong:

One-brick walls, arches, and reinforced brickwork are volumetric; brick nogging is typically counted differently or by area/number but is not the standard contrast used in this question.

Common Pitfalls:

Assuming all brickwork is m^3 regardless of thickness; forgetting that thin partitions attract m^2 measurement to reflect construction method and pricing.

Final Answer:

Half-brick (about 115 mm) partition wall
