Riccardo Petaccia, an avid Spurs fan, is the structural steel manager for main contractor Multiplex. 'I've been watching the FA Cup Final every year ever since I can remember and when I heard Wembley was being rebuilt, I knew I just had to be part of it, ' he says.
His role has ranged from finding the right spanner to tighten connections on one part of the stadium to deciding how site operations can continue when the tower cranes are out of action due to high wind.
But Petaccia is not grumbling.
He still looks at the structure with wonder. 'To think we built it [the arch] on the ground, rolled it to 112- and got it to less than the width of your hand from where it's supposed to be is just amazing - a real credit to everyone who worked on this job.
