I am aware that the usual procedure for removing a load bearing wall is to use a heavy RSJ and relative checking of foundations + pillars etc... I am thinking of using another method via extra joists running perpendicularly under existing ones. I reckon that 5-7 joists mounted onto masonry joist hangers around the centre (around the area of the wall to be removed) should do the job neatly. This will also reduce the height of the ceiling from 2.70 to a more manageable 2.50m. I reckon that in this way the loads are better spread out (along 4-5 metres) rather than having a single RSJ with relative highly concentrate loads on lenghts which spans only 100-300mm.
Any comments, suggestions?
