Another from me. We ran a 2nd lift in at the correct height although attached at the back is a seperate low level garden room. If we carried the lift at the same height it would be too high for the roof level on the lower building. We stepped the scaffold to 350mm down from the rest of the 2nd lift but safety officer said height gap should be no more than 250mm 
any help and literature to back up would be good
