Wembley Stadium London

From 2004 until 2007, Hollandia UK supplied resources and equipment for Hollandia Infra for the Site Construction for the New National Wembley Stadium. Following the completion of the Bowl, Fixed Roof, Moving Roof and Arch, Hollandia UK entered a maintenance contract with the Wembley National Stadium Limited in 2007 and also provides operational assistance for roofclosures and roof openings during events. 

New Stadium

Wembley Stadium in London has been chosen as the new England National Stadium. The old stadium has been completely rebuilt in order to ensure that the stadium, dating from 1923, meets current requirements. The new stadium has been built on the site of the old Wembley Stadium. With this, the largest indoor football stadium in Europe has been realized, which can accommodate 90,000 visitors. The arch construction, on which the partly fixed and partly movable roof is suspended, guarantees the
spectators a covered seat with unobstructed views and a shadow-free field. The new Wembley Stadium is currently the largest indoor stadium in Europe. Hollandia’s scope for this special project concerned the design & construction of approximately 16,000 tons of steel structures for the New Wembley Stadium in London. In close cooperation, the Hollandia yards in Krimpen a / d IJssel and Heijningen supplied most of the steel structures for this eye-catching project. It is one of the most spectacular projects that Hollandia has ever realized. The project included the design, manufacture and assembly of a movable roof measuring approximately 200 x 300 m.

Largest arch construction in the world

The stadium is characterized by a circular half-timbered arch with an internal diameter of 7 m and a steel span of 315 m, which is deviated by approximately 22 ° and has a length of 133 m. The further roof construction is attached to the arch. This arch is the world’s longest unsupported roof construction in one piece. The sunroof can be adjusted for athletics, concerts or football matches. The feet of the arch are approximately 300 meters apart. The stadium roof has a diameter of approximately 250 meters and covers a space of approximately 200 by 300 meters thanks to the mobile elements. The roof hangs about 50 meters above the turf.

Ultra-light roof construction

In order not to overload the arch, the roof construction has been largely optimized to save material. This has resulted in a special and ultra-light roof construction. However, this has made the assembly of this roof extremely complicated. For example, the amount of mounting material exceeded the weight of the roof.

Five steel structures

The following steel structures mainly form the stadium:

1) Load-bearing arch (“Arch”)
2) Load-bearing construction for stands (“Bowl”)
3) Load-bearing construction around stadium for the roof
4) Fixed roof, consisting of the North and South roof
5) Movable roof

Erecting

The roof hangs from the large arch. The force transfer to this arc has taken place in three phases:

1. Transfer the arc from the temporary cables to the final cable network.
2. Hang the north roof on the arch.
3. Connecting the south roof to the north roof via the girders.
