Data origins of ADB
« on: October 18, 2021, 01:17:20 PM »
I'm doing some research into the formation of Approved Doc. B.

Can someone point me in the right direction with regards to the data/ evidence that is used when specifying various recommendations within the document? i.e. travel distances, fire ratings etc.

Does it stem from the Post War Building Studies?

Thanks in advance

They originate from post-war studies, not sure where you can find them

Some does, some doesn't. Not all is PWBS. One recommendation was based on the size of the house I was living in at the time.

Were you ridiculously rich (i.e. living in a mansion) or did they pick the equivalent of the "man on the Clapham (or Glasgow) omnibus" house?

Neither. It was just a nice 5 bedroom house, with 2 reception rooms and incorporated a small office. But a specific rec of ADB (and the tech handbook in Scotland and TBE in NI) is based on it.

Why 200m2? I once asked this of a belligerent BC officer who could not be satisfied by a Grade D LD2 system in a new property that strayed over the limit by a mere 20m2. Floors were ripped up and cables and detectors changed all because the walls in CTs house were built as they were?

I feel there should be some sort of recognition of this - perhaps a nice pale blue plaque on the wall of the house?

Some of the research that went into the 2006 edition can be found here

You can still buy the key volumes of the post war building studies.

Often code writers have to come up with arbitrary figures for what is "reasonable".

Imagine a bunch of folk at BSI saying "well we should have these in a big house". Then they have to decide at which point a house becomes big. (enter CT stage left)

I think I'm past caring Colin.

Another good reference is Malhottra's "fire safety in buildings" which is a good snapshot of what was being thought about circa 1980 ish.  https://www.brebookshop.com/details.jsp?id=328055
