As Insider said on another thread
"Because the arch is curved both vertically and in plan, it is an extremely complex geometrical shape. Watsons have allowed for this, by making some of the flanges oversized, to allow for modifications - but this means that final adjustments cannot be made until it has been put into place.
However it is much easier to make these adjustments on the ground, and for this reason it is likely that you will see each of the sections of the arch being lifted into position and then taken down again over the next few weeks."
