Apologies if you think I'm implying anything, all I was asking for was a basic understanding of your approach to your CBA so that I could determine how accurate it is and whether other elements had been accounted for.
In terms of the reason why I do not post some projected costings, well, it's an area that I would need to understand better before I made that kind of call. As it stands I'm not in possession of anywhere near enough facts to publish that kind of assessment or analysis, which is why I'm curious to understand what information you're working with and why you're confident that you're correct rather than curious what everyone's opinion is...

Just been reading February’s HSW, page 9; Tussaud’s failed bid to overturn a £495,000 penalty after a member of the public fell from a castle bridge.
Merlin (Tussaud’s) said the risk “was not very foreseeable” given that millions of people, including children, had crossed the bridge over many years without incident, and the evidence of a defence expert stated that the possibility of an injury was one in four million.
Perhaps they should have painted a line by the parapet wall, just like our rail stations?? or had a SSoW that had a guard doing his best to keep the public away from the edge whilst doing three things at once??

Ray Rapp #84: The other parts of the story my learned colleague has failed to mention is that the EHO had twice made aware to the operator (Merlin) there was a risk of falling from the bridge before the accident. Moreover, "the accident was foreseeable and would not have occurred if Merlin had undertaken a proper risk assessment...would have identified the need to provide barriers at the sides of the bridge". So, perhaps not as improbable as the appellant would have us believe.

Ray, are you stating that network rail are not aware of the risk of falling from the platform? meanwhile we still have these accidents happening, see below.
