Double Scaffolding or Mason’s Scaffolding

This type of scaffolding is stronger than the single scaffolding. This is similar to that of single scaffolding except two rows of standards are used. Out of these two standards, one is close to the wall and the other is 1.2–1.5 m away from the face of the wall, Fig. 22.5.

Here, no holes are made in the wall for putlogs and the putlogs are supported at both ends on ledgers. Sometimes diagonal bracings and inclined supports called rakers are provided. This type of scaffolding is particularly used for stone masonry construction.
