I have a different view on the role of the Fire Authority in terms of consultation on Firefighting vehicle access for domestic property.
In very general terms, the purpose of the consultation process is:
1. To advise the BCO / AI on the Fire Authority's opinion on compliance with the functional requirements of the Building Regulations, using the quoted document as a benchmark
2. Considering variations from that benchmark standard, taking into account compensatory features etc.
3. Advising on any additional means that they consider necessary to comply with the FSO.
Clearly there is no legislation that the Fire Authority enforces on occupation that is applicable for vehicular access to domestic premises, so item 3 above can be dismissed.
Consultation is only likely when the BCO / AI has already established that the benchmark standard cannot be achieved so point 1 can dismissed.
Compensatory measures for variation from a benchmark standard, may be argued is some cases. However, any such feature, cannot be enforced or be required to be maintained once a completion certificate is issued, so in my view this is a flawed solution.
My view is that approving authorities often feel under pressure to approve a scheme which does not satisfy the Building Regulations, when using ADB Part B5 as a benchmark, and seek Fire Authority support for that approval, to make them feel more comfortable with their decission.
