FOR SALE: 3 metre RSJ

[krhall]

Anyone in need of a 3 metre steel RSJ?

If so and you are able to pick up this week from Dartford, make me an offer.

Bought 2 for two walls being removed and the building inspector only wanted us to put one in - go figure!

Cheers...

If it doesn't sell make it into the biggest ground anchor ever!

Ive four more if anyone wants to buy them cheap as well, two 6ft ones, two 8ft ones.

Did the building inspector actually do any design, or did he just eye it in?

Obviously he's seen it, but if it's a cavity wall, or 215 wide you shouldn't really have more than 1/3 unsupported.

Firstly, if it's a solid 9 inch wall, a single 8inch wide beam is ideal, I've done this many times.

Secondly, it's not the building inspectors job to change anything regarding structural loads, he's there to enforce that the beams and the removal of the wall are carried out to the calcs done by a structural engineer.
Building inspectors are not authorised to make these decisions, that's why 3rd party structural calculations are required, this takes away any risk from the building control office.
So I'm suprised he's made this call, unless the op hasn't mentioned everything, hey I'm only a rough ass builder so know very little about the calculation side of things, but I can size a beam up by looking at any job knowing what I'd put in would be at least bigger than the calcs would require and so would the BCO, but I wouldn't take the risk without a calc as back up.

Thats what I was worried about. Sounds like an engineers done some calcs for 2 beams, and the inspectors told him to put one in......which would be odd in my experience.

Yeah, an 8" beam would be wide enough for a 9" wall, but if he'd brought 2No. 178x102's for a 225 wall but only put one in, then there could be issues. Any way, he's trying to sell it, not asking for help so I'll butt out.

Yep I agree mate, Every BCO I've met wouldn't make that decision even though they probably know what's required, it's not their job.

Like you say the op is selling the spare beam so I'll butt out too, good luck with the sale, might be worth putting the actual sizes of it btw
