Difficulty: Easy
Correct Answer: Half-brick (about 115 mm) partition wall
Explanation:
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:
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:
Identify items usually in m^3: full-thickness walls, reinforced brickwork, arches (unless exceptionally specified).Identify thin/planar item: half-brick partition is effectively a wall by area.Therefore, the case NOT measured in m^3 is the half-brick partition wall (measured in m^2).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
