How to compare the setup

These are fixed ScaFix examples, not customer jobs. Use the wall dimensions and roof shape stated with each example.
Compare the same system variant, bay lengths, scaffold depth, deck heights and access. Matching house dimensions alone do not give matching parts lists.
The displayed quantities are calculated by ScaFix's engine. Check the setup against the manufacturer's assembly instructions and the actual job; a parts list is not a structural calculation.

Limits

The number of wall ties follows the system's tie rule. Their positions must be checked against the manufacturer's assembly instructions.
Round corners, silos and hanging scaffolds are in Pro. A round scaffold is not a standard configuration and needs a calculation or the supplier's documentation. A hanging scaffold (Layher Allround and HAKI Universal) always needs a structural calculation from the supplier or an engineer.
