Placement of steel column in external brick cavity

You should refer to the specification provided by your structural engineer. No doubt they have provided the calculations for the steel column together with the holding down details & possibly a padstone specification & bearing capacity of the cavity wall. You shouldn't be asking this question if you have engaged the services of a structural engineer.

It wouldn’t be advantageous putting it in the middle as it’s only your inner wall that is load bearing .

Hi There, I will install the column between the blocks on the internal part of the cavity wall. Than you can nail wall starters to the column and just cary on the job. Of course to avoid any cold bridges you will have to isolate the column too. In the design phase, the structural engineer should show all necessary connections and calculations. Hope it helps

If you haven't already I would seek advice from a structural engineer as they will be able to provide all calculations including size of the steel required

Hi, without looking at a detailed specification, it is impossible for anyone to determine the exact position of the steel column! If the column is shown central of the cavity (by a qualified structural Engineer) more than likely, it will need to be resin bolted to a suitable foundation! Ultimately, the void in the column would need to be fully insulated, this can be achieved using a 100/150 celotex insulation and expanding foam, to keep in place. Also, it would be good building practice, to install a vertical damp course, to avoid any water penetration through the brickwork.
