Structural Engineer

lnjk

I have had a couple of builders in and they have said that as I am after a load bearing wall to come down I will need to get in a Structural Engineer. 3 builder have said they would charge around £200. I had one up yesterday and he has sent me a quote for £800 odd pounds!

Now the job it one wall knocked through an internal wall and then what was the existing external wall (as a single story extension has been added) also taken out. Now all builders have advised a t design with the top of the T being the main external wall bolted onto the other RSJ. When the structural engineer came yesterday he started talking about put in a window type frame which means digging the floor out for stability!! I am really not sure if this amount of work is needing done.

Any advice appreciated Thanks .

I'm leaning toward the frame design...What sort of span is involved?? What is the structure of the existing back wall and how stable is it?

You want a 9.5m wide opening in the back of your house? That's a hefty piece of steel you're going to need, that must be pretty much the entire width of the back of the house, surely?

For an opening that wide, I would be considering a frame as well, to be honest. And if you put a frame in, it needs to be sitting on some solid footings, hence needing to dig part of the floor out to get back to solid concrete.

Thanks for all the info. Basically we were just taking the adjoining wall down but came up with the idea if we take the whole lot down then we can have an open plan large room. I may leave in the main wall as it is only about 1500 as their are already 2 double doors either side going into the 2 rooms we want to knock together. Would have liked the 3 rooms knocked together but think it may be a v large job

Hubby just come in and i have given the wrong dimensionless the wall is 5500 (it was the garden i was looking at) would you still consider a frame for this size? Thanks

I think 5.5m is a fair old span and i would be thinking square frame still but thats just my gut feeling. Do it right first time..you dont want the house falling down..

I was going to use the only service them but how do they know the condition of the bearing walls etc. I payed around £180 for a structural calculation. I wouldn't always listen to what builders say, I phoned the local council and checked things with them before listening to builders. One said to me that you don't need steel use a concrete lintel, which the council werent happy with. Builders will have a rough idea of the size of steel needed as they will oversize it just to be safe, if they do without calculations.

Jus remember,its your home and its your home that will crumble if it goes wrong and where will the builders be then? Get a professional certified opinion.
