Layher Allround scaffold package for a 98 m² wall

The package

Wall area and scaffold area are two different numbers. Wall area is the wall you work on: 12.28 m × 8 m ≈ 98 m². Scaffold area is the face of the scaffold itself: 12.28 m long and 7.5 m from the ground to its top ≈ 92 m², not the sum of the decks. Here the scaffold area is the smaller one: the top deck is 1.5 m below the top of the wall, and the scaffold ends 1 m above that deck.

Why 12.28 m gets 4 bays

Layher Allround has one bay length in ScaFix's catalogue, 3.07 m, so the engine builds every wall of whole 3.07 m bays and picks the number that comes closest to the wall's length. 12.28 m is exactly 4 × 3.07 m, so the scaffold is exactly as long as the wall. On other lengths the scaffold ends up a little longer or shorter than the wall, as the table shows. Computed by the same engine at the same height (8 m); the difference is the scaffold's length minus the wall's.

This is a fixed example: level ground, the settings «Platform to roof» and «Bottom decks» off. ScaFix is a planning tool, not a structural calculation or an approval of the scaffold. Always check the scaffold against the manufacturer's instructions and the job.
