The main structure of the stadium is built from many different

components and materials, I can tell you that the main contractor

assigned for building of the stadium was Multiplex (UK) The design

of the new stadium is both functional and architecturally

significant. Sir Norman Foster designed the arch and the roof

structure. The stadium's unique features include retractable roof

panels and the arch. These were developed in response to the

particular requirements of the stadium, one of which was the need

for a high-quality grass pitch in order to achieve UEFA 5 star

stadium status.

The arch itself is not just a cosmetic feature; it supports the

north roof and a sizable area of the south roof. The arch has a

lattice form consisting of 41 steel rings (diaphragms) connected by

spiralling tubular chords and is formed of 13 modules with two

tapering end sections. The arch (7.4m in diameter at the base and

weighing 1,750t) tapers at its ends and is supported on 70t hinges

which are in turn supported on concrete bases founded on piles 35m

deep. Inclined from the vertical, the arch is held in position by a

series of forestay and backstay cables tied to the main stadium

structure. The 50,000m2 roof is essential to the operation of the

stadium as a sporting and concert venue. Weighing some 7,000t, the

roof has a number of retractable edge sections which can be

maneuvered to allow direct sunlight to reach all parts of the grass

pitch to allow the pitch to achieve top quality. Construction of

the arch began in 2003; it was fabricated on-site using steel

modules fabricated by steel subcontractor Cleveland Bridge.
