I don't mind if I change the DIRECTION OF THE COLUMN. ] This is the common mistake that all engineers make. If architects place columns and send them, this is a preliminary design. The actual static design belongs to the engineer. The dimensions and layouts of the columns are determined by the engineer. There are sometimes indispensable architectural aspects. For example, the points where the doors are. If you make a play in the direction of the column, the door removes its functionality. If that column needs to be put there in terms of bearing, the architect must change his project. This is the general method anyway. The architect sends his project, the engineer makes the static design, makes the calculations. Then he sends the project back to the architect. The architect examines his project according to the new situation. This is the process continues.
