That's what I think:
You can use the 3D overlays. These should be much better than the Gif you mentioned. But from the outdated Gif you know that some of the upright columns were extreme deflected and stood up again. We can just hope that they don't leaning in all directions.
You mean the columns are 1002, 902, 1004, 1005, 1006.
In the floor drawing you use, 902 is misplaced; It must be aligned with 1002. Also all visible columns should be from the same row, 900 or 1000. Because the next row is hidden by the dust and could not be visible.
I would tell the columns are 1004, 1005, 1006(invisible), 1007, 1008. Is it possible?
