Often scaffold frameworks will require more than simple base plates to safely carry and spread the load and only on concrete or similar hard surfaces could one do without. Base plates are necessary for surfaces like pavements or tarmac. For heavier duty scaffold much more substantial baulks set in concrete can be required. For softer or more doubtful surfaces sole boards must be used, beneath a single standard a sole board should be at least 1,000 cm² with no dimension less than 220 mm.

A working platform requires certain other elements to be safe. They must be close-boarded, have double guard rails and toe and stop boards. Safe and secure access must also be provided.
