How are large towers made round, and what are the same processes used?

It is a tower with an inner diameter of over 10 meters. During its segmented construction, after the supports were in place, the ellipticity was around 30. When installing the internal components of the tower, it was found that the bolt holes in the connection plates of the liquid drop plates on one side were too large, while those on the other side were too small. It is preliminarily assumed that this was caused by the process of rounding out the cylinder shape. I would like to ask my colleagues: how do you round out such structures, and what are the specific procedures used?
The interior of the tube section is supported by a “M”-shaped structure, and the joints between sections are reinforced using internal or external arc-shaped plates to maintain circularity.
Inside the tube section, support in a “cross” or “plus” shape is used depending on the inner diameter of the section; along the entire circumference inside, or at the points where the diagonal supports come into contact with the tube wall, reinforcing arc plates are installed to press tightly against the tank wall.
It’s over 10 meters in diameter – that’s really huge. Are the ring joints welded vertically or horizontally?
Depending on the thickness and diameter, there are those with horizontal submerged arc welding, as well as those that are formed in sections vertically
