Hello,
I've just realised from the specifications and drawings of my single story extension (there is a 5m clear span requiring a 5.4m 203x133 30kg/m UB with 10mm plate), that there is no mention of padstones for the RSJ.
Before I go back to the man who did the drawings few years ago, is this something I have to get calculated? I don't know padstones so don't know if they come in different load ratings or size requirements or whether when my builder starts it's simply a case of get a padstone of type PAD12 (from a random google search) 440 x 215 x 102, for example.
thanks.
