Fire Risk Assessments (FRA)

Olli is able to provide 4 types of fire risk assessments


Most common type of FRA – Non-Destructive – usually sufficient for most purpose-built blocks of flats and conversions, assessments of common parts and front doors.


Is similar to Type 1 in the sense that it only includes the common parts of the building. However, it involves an element of destructive “sampling” – carried out if there is good reason to believe there are serious structural flaws that need further investigation.


Assessment goes beyond the requirements by considering the flats as well as the common parts and doors.


Like Type 2 includes destructive assessment to the common parts and to the individual flats
