Gwangmyeong Velodrome

South Korea


Tony Gee provided a full construction engineering service for the roof structure of the 179m x 133m sports stadium. The roof acts as a dome and comprises a perimeter tension ring, a central compression section and interconnecting trusses. We ascertained that a three stage erection method would provide the most economical solution; the central compression section was assembled at ground level, lifted using strand jacks and supported temporarily on towers. The second phase was to install the tension ring, supported on bearings around the perimeter of the stadium and the trusses that frame between the inner and outer sections. Finally the central compression section supports were removed in a jack down operation until the roof was a freestanding structure.

Tony Gee undertook the detailed design of all the temporary works including the foundations, jacking and support towers as well as advising the contractor on erection sequences and specific support arrangements for structural sub-assemblies. Structural analyses of the roof were undertaken for all stages of erection to check stress levels and also to establish erection tolerances and jack down operational limits. We provided site supervision for all critical lifting and jack down operations on site.
