If you did have a list of acceptable alternatives then can you do things that aren't on the list?
of course, but we base these on benchmark standards.if you want total flexibility with some one making their own judgement on what is safe, why bother with such guidance such as BS or DCLG guides?If you are basing competence on experience and knowledge-where then does that come from?Ultimately of course it is the courts that decide what is 'acceptable', reasonable etc, but as few cases have gone before them we are left to get on with it.
All I am saying is, if there was a benchmark standard that said something along the lines of, for example,' if a sprinkler system is installed to such and such a standard.......... certain elements would not be required to be fire resisting' (or what ever).This is no different than other options /alternatives given in Building Regs/BS/DCLG etc.
This would give BCO's/FSO's the confidence to be able and accept different options, instead of the adhoc way it is done at the moment.You must remember many of them will have to follow their employers policy, and employers are slow to promote/reluctant to accept a policy that it outside benchmark standards.
I am trying to promote a particular client to install more sprinklers in buildings, but at the moment have very little to offer in terms of savings (they are self insuring).They have recently completed 10 large Resi care projects where they have put in a (non mandatory) near life safety system(the cost of making it a full 'life' system would have been minimal), but have taken the decision not to relax any physical measures because they do not want to take a chance without some form of central acceptance (Politics comes into it).So they have a very expensive property protection system that will have the spin off of making the home safer and easier to manage, but they won't rely on it,because they chose to have a policy of having them as a 'nice extra', and if they chose to stop maintaining it and switch it off, it has no effect on their procedures.
