I was about to re-check the tables for joist dimensions in floors -
this used to be in the appendices of Approved document A

http://www.planningportal.gov.uk/eng...000000067.html

Free to browse, download etc.

The new version of document A has chopped those appendices and refers
instead to a TRADA publication.

Go look up the publication:

http://www.trada.co.uk/techinfo/libr...&Submit=Search

and it's available to TRADA members only - that information used to be
public domain!

You can of course buy the printed version for 21 quid

http://www.trada.co.uk/bookshop/view...s_in_dwellings

For now the old version of approved document A is still available
online - but with no guarantee that the info meets current
requirements.

I'm livid about a public document, paid for by my taxes being ripped
off like this.
