How do you know it could take 600kN?
Here it is. A red X marks the spot. There is a block wall just below on the picture that could be built into?
I would say to your SE "you cannot be serious!!!"
The 152 x 89 will be carrying very little weight and would not need a pier that size. In fact, you could do away with that pier entirely as follows:
Instead of putting in two (heavy) pre-cast concrete lintels, put in one 203 x 203 x 46 (with a wider plate tack-welded on top if it is supporting a cavity wall rather than a 9" wall).
Run the steel beam on to a decent length of padstone (say 300mm) and seat the 152 x 89 on the bottom flange. Voila - no pier!

I think youre talking about beam5 blue X? The architect forgot!! to draw that wall on the proposed plan and that threw the S/E a bit. I explained to him that the wall behind the stairs was staying and can we make beam 5 shorter and put beam 5 on that.
The pier/column Im stuck on is the red X. Or am I misunderstaning you?
Sorry, my mistake -I misunderstood.
If the short retuen wall to the cupboard(?) is non-structural, then a 215 x 215 or 215 x 330 brick pier would be fine, depending on the load the beam is carrying, and assuming the reaction from the beam could be centered over the padstone.

Make sure your PI insurance is well up to date.
Ok thanks. On a new 600x600x400 pad. Unfortunately the existing Foundation there is only about 300mm wide so there a bit of extra work I reckon.
Well it's it's our own house so I'm not sure if Pl is any good. Although it would help with the hire in plant insurance. I was thinking of starting a thread on another forum for suggestions as to what insurances are suitable.The house insurance is is about £150 extra as I declared there's building works going on. I don't think that covers us from the start of this wall down business until it's signed off by the BCO. And I doubt any damage caused during works is covered either.
Slenderness ratio?
small-area reduction?
Partial safety factor?
Characteristic compressive strength? (Won't be 7)
