Construction of roof structure, cable suspended structure, for Pusan main stadium is adapted a lifting method that is VSL lifting system. 5 processes are practiced for erection of the roof structure including the first lifting process for erection of upper cables and the second lifting process for erection of lower cables. Since all cables of this roof structure with two open spelter sockets are determined their length, some cable were wrong length, he roof structure would be unstable. But, At complete of erection for the roof structure each cable is attained to theoretical tension force with average 4% errors.
