TING KAU BRIDGE
Location:Hong Kong, China Description:The Ting Kau Bridge in Hong Kong is one of the few multi-span cable-stayed bridges ever built, and with 1177 m (3862 ft.) of cable-supported deck, it is one of the longest cable-stayed bridges in the world. The unusual feature of the bridge is its two adjacent main spans with their stabilizing cables, which run diagonally from the top of the main tower to the deck near the side towers. With further stabilizing cables in the transverse direction, the towers of the bridge appear like masts of a sail boat. The arrangement of separate decks on both sides of the three towers contributes to the slender appearance of the bridge while acting favourably under wind and typhoon conditions. Each deck carries three lanes and a hard shoulder. Total length: 1177 m (3862 ft.)
Client:Highway Department of Hong Kong Owner:Ting Kau Contractors Joint Venture Scope of Work:Buckland & Taylor Ltd. provided specialized advice and directed the Contractor's erection engineering design team for this cable-stayed bridge. Acting as the technical link between the Contractor's engineering team and the Designer, we developed and optimized the erection scheme to successfully minimize the time required for erection of the technically demanding main bridge deck superstructure. We developed detailed methods and procedures for deck erection, deck closures, stay installation and erection monitoring and were responsible for calculation of cable stay lengths, final stay adjustments, and final deck geometry. We were also responsible for temporary works and procedures to restrain balanced cantilevers during erection and developed procedures for transport and heavy lift of 200 tonne tower heads and 50 tonne tower lateral struts. Completed in 1997.
