Re: How Can I Fix My Mistakes Can You Help..? These are my fixes. I hope it works for you. I suggest you solve semi-rigid. It would be correct to place the tiles in the stairwell and add the ladder. The connection point of the K30 beam on the floors to the column was problematic. In the foundation, the foundations connecting the 42, 46, 56 columns were built continuously and in the same direction. Most importantly, the s51 column has been changed direction. I wish you good work. N. YILMAZ
