In May 2007 competitors from all over the World took part in the First World High-Wire Championships in Seoul, during which was a Guinness World Record attempt for the longest high-wire crossing, which was designed by Tony Gee.
The wire stretched 1000m across the Han River, supported on 25m-high temporary towers on each bank. The design was complicated by the need to meet a number of unusual serviceability criteria, including the steepness of the cable and clearances for balancing-poles from secondary stabilising cables and guys, as well as more normal concerns such as shipping clearance constraints. A very short programme for design and installation necessitated close co-operation between the designer and contractor.
Tony Gee was also responsible for development of the erection methodology and specialist temporary works, including shore-based cable handling temporary works and river-borne temporary rafts and associated equipment.
