A unique 320m diameter fabric covered dome, suspended from a series of twelve 90m steel masts and held in place by over 70km of high strength steel cable.
The Teflon-coated glass fibre fabric roof of the Millennium Dome is supported on a network of cables. The network was laid out on the ground and winched into position. The fabric was delivered in 144 panels, making up the roof's 72 segments.
Extensive groundwork was needed on the site and 8,000 concrete piles were driven. Concrete was also used for the 80,000 sq.m. floor slab and the bases for the masts. The horizontal and vertical forces from the cable network are all taken by a reinforced concrete ring beam, 6m wide and half a metre deep, which also formed part of the foundation works.
The completion of the structure was celebrated with a topping-out ceremony on 22nd June 1998, exactly a year after the day the first pile was driven.
