The risk profiling isspecific to a building or building design. If you change the use, say from an office to a shop, the risk profile changes and the factors that make up the profile are different. Therefore, the travel distances, exit widths and type of alarm can change with a change of use. This could end up with narrower exits for doors and stairs and longer travel than the risk profile would allow. The only way to monitior this as it would not necessarily appear in an FRA is for the enforcer to issue an Alterations Notice to ensure that they are consulted with regard to what was agreed at design stage. Afetr all, now it is an existing building it is the ebforcer role to enforce under the RR(FS)O. Quite difficult to explain in words, you have to understand the tables, all 16 of them, and how they make up the risk profile.
