Structural Engineer Design

[rikaka]

Hi All,

Looking for some advice/reassurance on the attached structural engineer design.

The house is semi detached two story around 100 years old, the walls are solid sandstone.

We are knocking down an existing kitchen extension and rebuilding a bigger version.

The steel work shown for the new opening is alot more extensive then i imagined. But at the end of the day i dont have much experience to base that assumption on.

I would appreciate if anyone with a bit more experience could cast their eye over it and see what they think.

Thanks

What do you mean by extensive?

He means expensive, so I would have thought some 152's would be OK or some 150 PFC's, the posts look excessive to me too, but I'm no SE. What's the opening size - looks about 2.8m but the OP needs to confirm. Flat roof? Which way are the joists spanning?

I don' really understand B2, there seems to be a wall with a single doorway and a beam all the way but then the padstone is in the middle of the wall?

Where's tony?
