Arup Associates has begun remedial work on the site destined to be the home of the £55 million Commonwealth Games stadium in Manchester. The 47,500-seater stadium (above) is also to be the future home of Manchester City Football Club when it leaves its Maine Road site after the Games in June 2002. It will take a year to convert the building for football use. The stadium has a circumference of 630m, with its highest mast 64m above the ground. Its acoustics have been tuned to enhance the crowd noise by using the underside of the roof and ramps, rather than stairs, will be used for safer spectator circulation.
