From photo I really can't. So I do admire and amazed by your confident in quoting RM200k for repair. Coz I can't see the extent of damage, how many floors, what is affected, and doesn't even know the cause. No original drawings, no details, no BQ, no proposal or rectification details and yet you can figure out the cost of repair.
You're really a very experienced person with high technical and management knowledge with know-how of the in and outs of construction.

I do not understand how Sheer Wall design as I normally heard it them as Shear Walls. Would you be so kind hearted to enlightened us how "Sheer" Wall works? And how do you know the failure is from load bearing?

Got a yellow profile pic guy say this is sapsap water aje, downplaying the issue, offering 200k to fix the issue.
In cases like this we want to UPPLAY instead of downplayying the issue, scare tactic works cause people lifes is at stake.
Over the weekend when I yamcha with my friend who is an actual building engineer,
they say cannot save d this building. Once ground floor start crack it will pull all the way to from ground floor upper floors, no doubt about it.

If they want save other blocks, they can try to seperate the carpark into sections, cut out the failed buiding AND failed shared columns to try and save other blocks.
But doing so would require an intense assessment of whether the other columns can hold the extra weight or stress when the failed ones is seperated, I highly doubt the technology and expertise we had
in malaysia. They would require to cut the concrete, etc to seperate the shared column and building.

Jacking it up is NOT A VIABLE OPTION in this case anymore, SHOULD NOT put into consideration.
Not to mention, "skim back" / "plastering" / "reinforcing failed column" is also NOT AN OPTION.

Just like a plastic pen, when u snap it, you could try to hotglue it back to a usable state where you can still use it to write,
but it will no longer has the previous hardness, and a slight bit of force or squeeze could deform it.
Same like concrete columns, when cracked or snapped or deformed, reinforcing from the outside it is just hotglueing it to make it looks more stable,
doesnt mean that it could withstand earthquakes or slightest bit of ground movement due to nearby construction.

how much developer pay you to come post this
