Prima Uno provided project controls and planning solutions to the main works contractor Multiplex.
Designed by Foster and Partners and Populous (then HOK Sport), it includes a partially retractable roof. A signature feature of the stadium, following on from the old Wembley’s distinctive Twin Towers, is the 134 metres (440 ft) high Wembley Arch. With a span of 317 metres (1,040 ft), this steel arch is the longest single span roof structure in the world. The stadium was built by Australian firm Multiplex at a cost of £798 million. The old Wembley closed in October 2000, with demolition originally intended for that December and the new stadium due to open in 2003. After delays to the project, with demolition first started in September 2002, the old Wembley was not completely demolished until February 2003, with the new stadium scheduled to open in time for the 2006 FA Cup Final. After further delays, the stadium was delivered nearly a year late, leading to legal disputes between WNSL and Multiplex, who ultimately made a significant loss on the project. The stadium was handed over on 9 March 2007. Budget £900 million.
