Tie Patterns/ etc
TG20:08 shows tie patterns for basic scaffolds.
Generally if it is a sheeted scaffold then the ties should be every other bay x every other lift, but this may change due to the geometry of the building and location.
If you are erecting scaffolds then it is worth purchasing TG20:08 as this is the Guide for Good Practice for Scaffolds in tube and fittings in the UK.
TG20:08 only covers basis scaffolds though.
Unfortunately it seems that a lot more scaffolds are requiring designs.
All the best
