what i assume ..... construction is precast and failure occur because of inadequate seating of precast panels..... precast slab panels even seems fine after coming down. sometimes unbalanced load after such failure could leads to progressive collapse.

these Cracks are in your Plaster because of improper curing .....

I don't see at the moment any thing positive except a mere monopoly show. This being said without any research on them as I don't even want to. It's just my perception without even knowing what's going on. Other members please participate.

There's a whole lot of discussion on the topic. PCA notes, mention it, to not use biaxial moments for punching. SAFE takes biaxial moments. If you check the punching manually with moment in 1 direction, it should be okay. Analyze in both directions but dont combine moments. Others suggested moving the water tank. I'd like to further add to this, to add a beam between columns, a stiff one, to ignore punching all together and save in raft thickness.
