When the first tier of scaffold is erected, check for plumbness and continue doing so as the scaffold is built. Where necessary, adjustments can be made by using the adjustable screw jacks on the base plates. Settlement or slight variations in the fit of the components may require additional adjustments as tiers are added to the scaffold tower.
