Need advice on Lintel or RSJ for load bearing wall?

[stanley897]

Hi all

Doing a kitchen refit and the end wall we are planning to knock through to our outbuildings just to make kitchen a bit longer as width only 2.25meter wide. The outbuilding which at the moment is toliet and old coal store so getting bricky in to take that all out and raise height of brickwork up to exsisting kitchen height. The walls are solid walls 2 coarse thick and above the kitchen is the bathroom.

Would I need beam calculations done for this small opening?

Or can i get away with a 2.6meter lintel or do I need a RSJ?

Can put picks up if need or anymore info.

Thanks for any advice[/b]

Are you doing this with Building Regs?

 

[stanley897]

Yes

If you are getting Building Control in, they will probaby ask you for structural calculations for the beam(s) and bearings. Best bet long-term is to get an SE to do the figures.
For that sort of span, two 152x89 UBs will probably be OK.

What sort of cost is a SE? Or seen on Internet company's that do the beam calculations with info and drawings etc for like £50 is that any good down that route?

Cheers for the help and advice

Those on-line things are only as good as the info. you put into them.
More importantlly, they don't see the whole picture. Sometimes, it is not just a case of forming a new opening and putting beams in. You may have to consider the supporting structure, and in some cases other issues such as lateral stability.

If building to reg's I guess you will be upgrading the walls, floor and ceiling regards insulation etc, yes?

Yes mate some of outbuilding walls need patching up and new plasterboard everywhere and insulation
