closed, must remain closed until the end of the match, so some matches may be completed indoors even though the sun has re-emerged. The roof was closed for the first time during a competitive Championships match at about 4:40 pm on Monday 29 June 2009, during the fourth round Ladies Singles match between Amélie Mauresmo and Dinara Safina. The first full match to be played with the roof closed was a men's singles fourth round match between British player Andy Murray and Switzerland's Stanislas Wawrinka. Play on Centre Court had never gone past 9:17 pm, but with the roof closed and the floodlights on, the match could be completed after dark – at 10:38 pm. Merton Council's environmental chief David Simpson said after Murray's late-night win that late-night tennis would not cause any problems. However, when the record late finish was surpassed in 2010 during a match between Novak Djokovic and Olivier Rochus which ran until 10:58 pm it was reported that Merton council had imposed a curfew of 11:00 pm BST on Centre Court. This was then exceeded on Saturday 30 June 2012, when Andy Murray beat Marcos Baghdatis in their 3rd round match, which was completed at 11:02 pm, in spite of the 11:00 pm ruling. On Sunday 8 July 2012, Andy Murray and Roger Federer contested the first Wimbledon final to be played partially under a roof. The roof was designed by SCX Special Projects Ltd and controls for mobilising the roof were designed by Fairfield Control Systems Ltd. and Moog who supplied the electric control system comprising electric actuators, servo motors, servo drives and closed-loop controllers. All companies undertake all the planned preventative maintenance. The roof's ten trusses each weigh 100 tonnes, and the total weight, including non-moving parts, is 3,000 tonnes. The total area of the roof when fully deployed is 5,200 m2. The cost of the roof has not been disclosed by the club, but is estimated at . Scoreboard The Scoreboard on centre court's present shape and layout closely reflect that of the original scoreboard installed in the 1950s, which featured manually inserted panels for player names and incandescent-lightbulb display of scores. In 1982, dot matrix scoreboards on the same layout were installed on Wimbledon courts. These were replaced in 2008 by full colour LED screens intended to provide full Hawk-Eye replays to the crowd in the stadium. Inscription There is an inscription
