An independent scaffold (freestanding scaffold) differs from a putlog scaffold in that:
Choose the correct answer
Independent scaffold is supported by the building wall at all levels
Independent scaffold has two rows of standards and does not rely on the building for support
Independent scaffold is used only for painting and finishing work
Independent scaffold cannot exceed 5 m in height
Correct Answer
B. Independent scaffold has two rows of standards and does not rely on the building for support
Why is this the answer?
Putlog scaffold: one row of standards + putlogs projecting into the wall (needs to lean on building). Independent scaffold: two parallel rows of standards, fully self-supporting — used when wall cannot be disturbed (renovation, repairs) or for multi-storey work. Independent is stronger and safer.
