The Arch was fabricated on site over a period of ten months. Companies and craftsmen from across the country have worked on the Arch. Here is a little more information about how this magnificent structure was pieced together.

• Arch consists of 41 steel rings (diaphragms) fabricated in the North East of England (primarily in Darlington and the surrounding area) and delivered to the Wembley Stadium site in thirds.
  
  
  
• 504 tubular “straws” cut to length on site form part of the structure
  
  
  
• Three assembled diaphragms or rings were positioned and aligned vertically within the on-site fabrication sheds.
  
  
  
• The diaphragms were connected together to form one Arch module 20.5 m long.
  
  
  
• Each module was then lifted out of the retractable fabrication sheds and placed on stillages on the southern side of the stadium.
  
  
  
• In total, 13 modules were assembled and welded together on site.
  
  
  
• A ‘Pencil end’ (or tapered end) was then welded to each end of the Arch structure.
  
  
  
• The pencil end sections were in turn attached to giant 70-ton hinges, embedded in concrete bases founded on piles 35 metres deep.
