Column Slightly Inclined on 1st Floor of the building
I work in IT and have no background information on construction or civil engineering concepts. I have recently purchased an apartment on the 3rd out of the 5-floor building under construction. Currently, the construction is happening for the 3rd slab of the building. I have noticed that on the first floor, there is only ONE column that is slightly inclined (approx 20 degrees ) and not 100% vertical. 50% of the column looks vertical, but the other 50% is inclined. All the other columns on the ground floor,1st floor, and 2nd floor look good. I discussed this with the supervisor at the site, but he says that is not a problem, and it will get rectified when the walls will be cement plastered. His answer didn't convince me. Can you please let me know if this will cause any strength-related or any other issues? Do we need to fix it? If yes, what is the correct procedure to be followed? Note: Red bricks are being used for walls.
