The Wimbledon tennis tournament gets underway on Monday, safe in the knowledge that the new retractable Centre Court roof will put an end to long periods of rain interrupting play.
The new 5,200m² roof, believed to have cost £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.
