Building magazine, the voice of the construction industry, reports serious concern on the part of Cardiff ctiy council - responsible for allowing the gig to proceed in the first place. Crowds jumping up and down on cantilevered stands cause a "ripple effect" placing the structure under far more stress than a "static" sports audience.
This week the council refused to comment on the threat beyond admitting: "Safety issues are being discussed with the Millennium Stadium plc."
Geraint Evans, operations and safety manager at the Millennium Stadium, said: "It's not a good idea to have people jumping up and down on a structure. Roman armies marching across a bridge used to break their step because if you march in time and hit the middle frequency of a structure, you can cause damage." But an official stadium spokesman said: "There's no danger. It's only a comfort factor."Reuse content
