Kurnal mentioned lack of supervision during the construction stage of a building. How right he is! I just finished the inspection of the electrical installation in a relatively large 5 year old civic building in which Building Control occupy a complete floor. One would have thought that they would have kept a close eye on the construction of a building which they themselves would ultimately occupy. The breaches of compartmentation that I witnessed above the suspended ceilings were significant. Massive holes left around duct work and other services passing through walls, poorly fitted fire dampers, some set so far back from the wall through which they passed as to be utterly useless, absolutely no records for the electrical installation other than a set of as-fitted drawings that were incorrect in many ways!
I witnessed the same slap dash situation in a nearby, recently constructed primary school. It would have been the same Building Control that would have been responsible.
Far from accepting the bona-rides of the building design and inspection team, it seems that a fire risk assessor may actually be the most important link to accredit the fire worthiness of a building. Maybe they need to be prepared to get down and dirty, don the overalls and scrutinise the dark voids above suspended ceilings! Perhaps, many do but I have seen a few fire risk assessors in tight dresses and high heels. I know what you are thinking, perhaps it was Colin Todd, but no these guys were much uglier!
