Wetroom Extension Foundations Question

Recommended Posts

Just had a call from the builder doing the work at my parents' house.

He had the Council Inspector out today to look at the foundations and was told he doesn't like the soil and so we'll need "Pelling" done to lay the concrete foundations which apparently is where a bore hole is drilled and the concrete poured into this and thence upwards to make the foundation.

Can't find the term anywhere on google (likely because I'm not spelling it correctly)

Advised it will be an additional £5k on top of the price (as it will be an outsourced company doing this) which is a bitter pill.

Some input and advice appreciate (included what the actual term is so I can also try to get quotes)

Architect advised getting a structural engineer out to review and advise and has given one name but I can't get through to him yet

 

EDIT: Googled it and it is "Piling" Foundations

Still it is a single room 5m kitchen/wetroom extension and £4-5k sounds like a lot?

Much appreciated. Spoke to a Structural Engineer who architect told me to ring to come inspect and he basically said "If building inspector suggested piling then that is probably cheapest way, so no point me coming" He's given me name of company he does the calcs for to get a quote...although not managed to get through to them yet

thanks guys. The builders had dug to over 5m when the inspector came and he checked down to 6m and was apparently not completely satisfied on 1 side.

The piling contractor who came said it's a risk aversion thing. Because a couple houses in this area have had piling in inspector will make the call against this - there is nothing in it for him to take that "risk" when he can just take a belt and braces approach and keep conformity in the postcode so sadly that's that (his site inspection view was also that we probably didn't really need it but as he's insisted....)

 

it's a 5m x 2.5m area which apparently needs 6 piles. 2 quotes so far one £2.5k (exc vat) and one £3400 inc

awaiting a couple more.

slight pisser is had we not had a partial grant for the wetroom we wouldn't have had to have the Inspector out for this and the £4k grant for my dad is wiped out by this added cost for the rest of the build....

aah well.

Next I'll have to see how much structural engineer will charge to calculate for the 2 beams for the 2 chimneys I'm getting taken out of their downstairs rooms to give them more space (again this was always extra charge to me) :-(

Make sure you get a competent contractor who is a member of either FPS or more importantly ASUC. The guarantees that these trade associations supply are worthwhile. Again, if you need any advice please ask, we are Structural Engineers who specialise in underpinning, foundation repair and foundation engineering. I dont mind reading through some quotes to make sure they have allowed for the correct loadings etc. Watch out because it is a minefield out there. +++

that's very kind of you, thanks.

I've only had 1 written so far.

definitely only going for approved company for this. I am completely risk averse in this project as it's for my parents.

could you PM your email so I can send them through probably sometime over weekend (mum's bday today)?

Will do. Please don't think that we are touting for work, we wouldnt be able to fit any work in for the next 6-8 weeks at the earliest. We just want to make sure you get the right foundation for your needs. Pm on its way. +++

OH absolutelt - I am very grateful for the advice.

I've just learned that someone should have submitted a bloody buildings reg application form and no-one has.

odd that the inspector came out last week if nothing was in place. MEAP gave us the "good to start" on the basis of a buildings reg notice, inspector came round at call of builder so I wondered wtf was going on when piling guy rang me saying building control won't come round to sign off the foundations and of course no no fecker is answering a phone!
