The All England Lawn Tennis Club recently unveiled its new retractable roof on the world famous Centre Court that will put an end to the familiar sight of spectators sitting beneath umbrellas waiting for a break in the clouds during the forthcoming Wimbledon tournament.
The new 5,200mÂ² roof, believed to have cost in the region of Â£80M, can close or open in around eight minutes, and is one of the first concertina-type moving structures ever attempted in the UK.
The 1,000t roof comprises 10 trusses spanning 77m across the court with nine bays of structural fabric. The ends of each truss are supported by a set of wheels that move along a track positioned on the new fixed roof of the court.
Architect Populous and structural engineer Capita Symonds designed the new roof, which was built by Galliford Try. SCX Group designed and supplied mechanical and electrical equipment.
