can't see them going back on design requirements at this stage, with regard to chasing loads back and working out exactly how over/under stressed each element is to ensure that the required factors of safety are in place, but a few more standard details would be helpful (not for me obviously!)........the problem with anything simple involving beams, for example, is that the guidance has to be impartial and can't mention any one particular 'brand' (steel ladder beams are ok as they have generic properties, but everyones going away from these).........in my opinion, in this regard, it would be up to the beam manufacturers to prepare their own standard details for their own beams in order to give scaffolders some breathing space.........
just my 2cents, for what it's worth..... (easy now........)
