Building Stones MCQ with answer and solution

Concept

In pitched (rock-faced) dressing, only the edges of the stone are levelled with a hammer, and the face is left rough.

Step-by-step solution

1. Recall the common types of stone dressing. 2. Pitched or rock-faced dressing: only the edges are made level with a hammer, and the central face stays rough. 3. Chisel drafting: narrow margins are cut with a chisel, not a hammer. 4. So the answer is pitched dressing.

Explanation

In pitched dressing the mason levels only the edges of the stone with a hammer. The middle face is left rough like natural rock. This gives a rock-faced look to masonry.

Why the other options are wrong

B: Chisel drafting cuts margins with a chisel, not a hammer. C: Rough tooling dresses the whole face with a chisel, giving parallel lines. D: Hammer dressing knocks off irregular parts of the whole stone, not only the edges.

Shortcut

Edges only, by hammer, rough face = Pitched (rock-faced).

Common mistake

Choosing hammer dressing only because the word 'hammer' appears in the question.
