How many does a scaffold need?
The space between two pairs of standards along the wall; its length is the system's bay length, for example 3.07 m or 2.57 m. ScaFix's example house (11.4 m × 5.3 m) takes 12 bays with Layher Blitz, 12 with Layher Allround and 16 with PERI UP, scaffolded all round. A straight 12.28 × 6 m wall takes 4 with Layher Blitz.
Bay in three systems
The example house scaffolded all round and three straight walls, each computed by ScaFix's engine with the system's own bay length and depth. The counts are the app's part group, which can also hold related parts (for example legs or base plates with the base jacks).
| System | Example house | 6.14 × 4 m | 12.28 × 6 m | 30.7 × 12 m |
|---|---|---|---|---|
| Layher Blitz | 12 | 2 | 4 | 10 |
| Layher Allround | 12 | 2 | 4 | 10 |
| PERI UP | 16 | 2 | 4 | 10 |
