Ceiling Deflection

[Nickfromwales]

Ah, pyramid roof no gable end wall....? First pic I saw up top, I thought was a gable.

 

Still doable with some steelwork or a bloody good chippy, assuming a dual cylinder platform could be formed to sit on the masonry wall. Depends on how badly you want the accumulator, as the minimum I'd recommend without pumps is a 300L.

 

To be honest, these are the kinds of jobs I used to love doing, especially when someone told me it can't be done .

Gasp. 

They built that brick to support the roof?

Purlin, or purlin struts have to sit on something that connects the roof to the founds? This is normal.

I mean the single brick on edge and simple (minimal)? contact of purlin to brick. 

Any tiny movement will rock that brick.

 

All I'd suggest is 2 bricks instead of one, laid flat, and a timber sole plate.

Being a pyramid roof, linear movement is unlikely. Most purlin struts I've seen have been a max 100mm wide timber, sat on a single skin masonry wall. Next to zero dynamic movement here other than wind-shear, so doubt it's an issue.

Yes, I'd improve that with a cut timber, birds-mouthed to accept the purlin so the flat side of the timber rested on the final laid course of brickwork, but I expect this has been there for multiples of decades without a single issue.....

OK I have misunderstood and thought it was new.

Need some advise regarding the following please… 

It would be a good idea to get an SE in to have a look at this. One thing that you need to look out for is when you muck about with the roof you can change the load paths on the floors below / any old beams and so on. This can become an issue. 

 

As a domestic Client you have a good bit of protection under the consumer protection act, the building regulations, CDM regulations and the HSE act 1974. 

 

Write to Oso and say that in the interests of fairness it would be appropriate to get a independent opinion. Say you are seriously concerned about the safety of the structure and give them 48 hours to respond. Point out that you have observed excessive deflections. Do this right away, don't delay! I agree with the other posters.. It does not look rosy as things stand and seeing the standard of workmanship gives me concern in terms of safety. 

 

You need to take the long view. At some point you will want to sell the house so best to get all your ducks in a row.

OSO should concede and take full ownership of this (hopefully isolated) feck up. Would be good if they do this with the least amount of resistance.

 

There's zero argument of like for like, or "there was one there before, we just replaced it" as the cylinder is larger than the original therefore it is a new and unique undertaking.

Hi all,

 

so way of an update. Apologies for the slow reply, full on at the minute with going on holiday. 
 

No call back at close of play from Oso on Thursday, so before I left on holiday Friday morning emailed them as it had been two days. 
 

They chose to respond with a statement they didn’t realise they had a timeframe, and disappointingly they are adamant and keep pushing it back to the subby who did it all in the first place and have a view he should fix the mess he created. 
 

I asked for the original design and calculations that had been undertaken but they ignore this. I also asked on what criteria they can say it’s OK for the short term, also ignored. I think it is obvious they just tried to wing it.

 

oso view is the sub contractor will do whatever is required to resolve, but I think Oso should take ownership and fix. 
 

I think I should push it out to a structural engineer at Oso cost to come up with the design that they install to take the weight.
 

The main guy from Oso is on holiday so has just left it to the subby to pick up when I am back from holiday. 

the lack or urgency and accountability from Oso is really poor.

Thanks.
I will email them tonight and explain I want an independent to view and design the frame so they know what they are doing. 
 

they can’t be trusted.

Yeh, sorry, pyramids all over! 
 

happy for you to complete if you want a challenge. 

LE10 on the edge of Leicestershire/coventry has its perks, a custard cream painted 1950’s bungalow and in need of someone competent!!

lol. Yea, done projects near Melton Mobrey and Lutterworth, one coming up possibly in Northants, so I do get around 🙃.

 

See if OSO offer to put it all right, and explore options to make the plinth big/strong enough to take that plus an acc’r . If you get proper stuck let me know.

That’s quite shit.

 

Didn’t spot this reply, so ignore my last.

 

The bottom line is, you paid OSO so your contract/agreement is with them. They decided to feck you over by giving the job to a 3rd party contractor so they need to fix this.

 

Reply to apologise regarding the timeframe, and say “you’ve got 7 days to respond with a plan to rectify before I look to seek losses via the courts. There’s your timeframe, you bellends”.

 

Shocking way to treat you to be honest, and you’d probably have been better off using a good local plumber and probably would have been cheaper and better. Ffs.

How interesting, I went to school in Lutterworth. 
I live just down the A5 by Hinckley so definitely doable and by in-laws are in Northants. 

once this is resolved if I can get the platform/plinth strong enough opens up the options to get an accumulator and/or pump.

 

just emailing them telling them they should want to pay for a structural engineer in any case so they can be assured it is acceptable. 
 

Be interesting to see what they say. 
they really are utter shit

Just saying that too actually so is a good point, paid Oso, it is their problem, they have accepted the install whether they want to accept it or not.

I mean, if someone pays my company to do a job, and I take a profit and hand the change to a 3rd party contractor, I am still 100% responsible for that job being kosher.

 

OSO is the company that is responsible here, as they took the clients money. What they did with that money afterwards is neither here nor there as far as a warranty claim is concerned.
