Dear Sefians,
This is regarding a site in Coimbatore.Structural drawings were issued for a small G+5 residential building. The contractor started the work without any intimation to us and finally one fine day it came to our notice that the work at site was completed upto the plinth level. When we happened to check the site we found out that all the columns were missing in their alignment and also in their position. However the contractor is now penalized and another contractor has been awarded the work.Now what should we do to correct these columns. I am attaching a pdf with the position of old and the new columns. Kindly have a look.


Regards,

Benny

Dear Er. Mallesh

Thank You so much for taking time in replying with a solution.



As you have suggested I will look into providing haunches to receive the beams and will also re analyse.

I am also planning to introduce columns between grid A and B along 1 and 4 so that the span is reduced.

I will say initially we can analyse structure for same column position. We can do its pushover analysis and then we can find its behavior and then we can reduce its Dead load as much as we can. This would help us  if situation won't satisfy then some system should be designed to take care of extra loading.

Thank You.

Dear sir.   I am from coimbatore itself. .i saw the pdf file....sir  kindky check verticality of rotated column ..its a big work to bring the column in original position .if the columns verticality is same from foundation ...then we can adjus the plans for this column position. I think thats is the ecnomical and best way to recover from this problem...
For that ...u must asure the verticality (rotation angle of column ) is same from footing top...if its aligned verticaly...then transfering  load will not be a problem...
Thank u sir...
This is my suggestion ...whatever u tried to resolve this  problem kindly update me sir...let me learn....sir..

Dear Er. Benny


With the twisted column you may try with band beam i.e. the width of beam is more than column width to cover the missing alignment.

Dear sir,            The columns are misaligned and there is no proper orientation of columns this is due to poor wokmanship and lack of supervison. Hence its a G+5 storied building we cannot take risks  by proceeding the work .kindly demolish those poorly oriented colums at the site and rebuild those columns. because with this poor orientation brick works wont be proper there will be major drawback in interior and exterior  looks and there will be a major misalignment in plinth beams also.
