Fixing a miss-drilled beam

[SteveBz]

I'm building a flat-roof extension on my house and I've got a guy helping me. Sadly he's miss-drilled the holes in the joists right next to the wall (within 70 mm) instead of .25 - .4 of the beam length. Actually, it looks very nice, but not in line with BRs. If we move the wiring (and pipes actually) to be in line with BR, how should I patch the holes? Can I put a steel plate over them? What to do.

Steve.

You've never go to bed at night, without brushing your teeth?

I am perfect........

Just use the holes you've drilled, they're in the wrong place that's all. Why weaken the joists further by drilling more?

If you are going to do job properly the do it properly, no bodges allowed.

Maybe your customers should check on the amount of expanding foam and grip fill that you use ;o))))))

Did I say I had done similar? I would have done the job properly in the first place, but if some fella without a "Part P" qually (joke) has gone and dared to drill a wee hole out of place, I would't fanny about with wooden pegs and sister rafters, complete waste of time. Have you seen the holes your average plumber puts through? never heard of a house falling down because of a few holes here and there, more PC BC non-sense.

Its all about liability, "if" something happens in the future then guaranteed someone somewhere will try to weasel there way out of paying for it or being screwed over for their decisions in allowing it.

Its like the 18th ed, most of its cack but you lot will adhere to it as it Electrical God's bible and if you don't you can and will be sued.

This forum is full of people getting their knickers in a knot over being sued, setting houses on fire, being put in prison, electrocuting others and who know's what else for committing all sorts of minor misdemeanours, including this one. How many have you ever known get sued/prosecuted/imprisoned or anything else for such? It's plain common sense, a few miss-positioned holes in a non-load bearing component like a flat roof rafter or even a joist are not going to make a jot of difference and are completely wasting your time, or even make it worse, to try. Just stick the boards up and crack on!

Did you do the cladding on the Grenfell Tower BTW?

Well I didn't know it wasn't fireproof did I? At least the no-nails helpd up for a decent length of time. On a serious note, I bet no-one gets to go to clink for that either.

Rules and regs...all very well.
Commonsense...but that requires some idea of what is required for safety.
I don't care about splitting hairs, just putting a good job together...
However, putting a hole through a joist in the "wrong" place isn't a problem...if you realise what kind of joist you are tackling.
Honestly, common sense wins...if you have a brain.

...All that is required,for evil to prevail,is that good BC inspectors,do nothing...

 

[sean_ork]

....... in a non-load bearing component like a flat roof rafter ......

You appear to think that a flat roof rafter isn't load bearing, just for clarity, could you confirm this please.

 

[PEG]

If only for pedantic glee,i shall state that it will be load bearing,in the modern,BC submitted plans way...

It will be designed for both static and dynamic loads,to accept stress due to temperature change and age,for wind,snow,and foot traffic (maintenance purposes)

There are other anticipated loads,which may be intermittent,such as waterlogging or scaffold bracing.

Superfluous additions,rely on such guaranteed load bearing abilities,such as PV panels,whose mounting systems,are designed around expected,hidden certainties not that a number of photovoltaic,tile crunching apex monkeys care,as they paslode and velcro to whatever,willy nilly,and sail off to change business name three times and dissolve forever,leaving those with both knowledge and a conscience,to sort the casserole of nonsense...

Breathe in...breathe out...

 

[sean_ork]

Thank you PEG, well put.

Yes of course it is load bearing, as regards the boarding and outer layers, and as has been said any weight that needs to go on it, like a roofer. But putting a few holes in the supporting timber (that has probably been designed to take that into consideration) is not going to weaken it in any was that is worth worrying about. Any one that does worry is just suffering from a lack of experience. There are joists and beams in houses up and down the length of the country with far worse knocked through and out of them and they won't be going any place anytime. If is was supporting a massive corner bath I might give it a bit of thought but otherwise? Steel sister beams, whatever next....

agreeee. if a hot tup was going on the roof with Vanessa Feltz in it, I'd be concerned. otherwise, just crack on.

 

[SteveBz]

Hi Guys,

Thanks so much for your input.

The engineer inspected it yesterday. He felt there was no problem. The joists are short enough for it not to affect it and he's going to write a note to BC saying so.

Thanks again,

Regards

Steve

At last some one with common sense.

Maybe the OP should ask the engineer to join the forum..........

Plumber went in too deep through a few joists........ so make sure your liability insurance is paid up.........

Hubble Bubble, Toil and Rubble. someone should have told Wally the window fitter to fit catnics.

Is this one of your little fantasy's Tel?

 

[telectrix]

first GRAMMAR/SPELLING ALERT!!! it's fantasies. apart from that, my only fantasy is an endless supply of Theakston's Old Peculier. .

That looks like a builder/developer error...the plumber might have dipped the ceiling,but it looks suspiciously like some other hero,finished it off

I have seen the exact same scenario,where some yuppie hero,dropped the front,to replace stone work,and thought the joists running across the front,would mean less propping...

Crikey Tel you're getting to be a right old Pedant.

Think I might of drilled into one of those composite 'I' beam joists today, putting up my Next luminaire in my new build today

Catnic?
Crikey!
Haven't heard that term for a while...
Not since I last told a client he needed to replace his Bessemer beam...
which wasn't a popular comment!

Do you mean a Bresummer Beam?

You've done your monthly rum quota in one day again haven't you, you naughty Pirate......

 

[Squid]

Tsk........

 

[pirate]

Bresummer beam!
Sorry...and me the total pedantic too!
Too much rum, for sure...
Anyway, he threw a whole load of magnolia paint at it, listed it through another agent...
and 2 years later the house still hadn't sold cos the surveyors weren't fooled.
Finally, I visited it again, and the master bedroom had fallen into the living-room!
How I laughed...as I walked away...
All those fancy chrome sockets didn't do the trick...
The fancy new kitchen was a waste of money too, cos the units had sagged several centimetres due to the floor joists sagging...
You won't be surprised to learn that the fuseboard hadn't been upgraded...
