Units of Measurement MCQ with answer and solution

Concept

Brickwork in arches is measured separately because extra rates are paid for arch work and centering.

Step-by-step solution

1. Check how each item is normally measured as per IS 1200. 2. Earthwork is measured in bulk (m³). No separate extra rate is involved. 3. Honeycomb brickwork is measured in m² as a normal item. 4. Arch work needs centering and shaping, so it costs more than plain brickwork. 5. So brickwork in arches is measured separately and paid at an extra rate over ordinary brickwork. 6. Answer is (B).

Explanation

Brickwork in arches needs extra labour, centering and careful shaping of bricks. For this reason it is measured separately from ordinary brickwork. An extra rate is then given for the arch work.

Why the other options are wrong

A: Earthwork is measured in bulk volume, with no extra rate for associated items. C: Honeycomb brickwork is measured in m² as an ordinary item. D: In reinforced brickwork the steel is measured separately, but the brickwork itself is not paid as an extra-rate item like arches.

Shortcut

Arch work = special labour + centering = measure separately for extra rate.

Common mistake

Choosing reinforced brickwork. There the steel is measured separately, but the extra rate for associated work is mainly given for arches.
