Here is the WSP summary. https://www.langford...mary.r1. SS.PDF
If Langford released the full report then we wouldn't have to speculate.
This has piqued my interest. The executive summary states:
The report recommends the immediate installation of temporary support below two transfer systems at level 2. The supports are to be designed to carry the loads indicated by WSP and must remain until either the EoR demonstrates sufficient design and constructed performance of the transfer system, or the necessary remedial measures are put in place.
Level 2 would appear to mean the second floor and that is borne out in the enhanced construction photos below that clearly shows floor 2 is the transfer slab - where massive beams "transfer" the load of the tower columns onto the main support columns that go to bedrock. Note the ground floor columns are not directly below the tower columns. My guess is that either some transfer slab beams are not massive enough, or positioned incorrectly, or some main support columns holding up the transfer slab are too small or positioned incorrectly - or a combination of both. I don't think this will be an easy, or cheap fix.

...
This is necessary to ensure the vertical load path is complete, and all gravity loads are getting accounted for in the structure. By transfer slab, I mean a level at which a column or wall bears on a beam or bare slab, directly below which there is no column or wall.
