weak according to what? Weaker than the rest of the structure? Weaker
against which kind of forces? Weaker than the current building code would
permit for a new construction? I can understand that an authority could
define criteria and asses buildings according to it and give them a class
like "soft storey", but this kind of generic class always implies some kind
of subjective judgement. I cannot see how this tag could be verifiable
apart from importing it from some authoritive source.
