Stonecutters Bridge, Hong Kong – 1,018m span cable stayed bridge
Maeda – Hitachi – Yokogawa – Hsin Chong Joint Venture
HK$2.76 billion / US$350 million
At the time of the construction commencement, Stonecutters Bridge was the longest stay cable bridge in the world. The bridge, which crosses the Rambler Channel and the entrance to Hong Kong’s container ports, forms part of the Route 8 highway project from Tsing Yi to Shatin. The project is a significant fixture on the Hong Kong landscape and visible from many parts of the harbour. It was designed by Ove Arup and constructed by a joint venture comprising Maeda, Hitachi Zosen, Yokogawa and Hsin Chong.
With a main span of 1,018 m (3,340 ft), Stonecutters Bridge is currently the third-longest cable-stayed span in the world, having been surpassed in length by the Sutong Bridge in Shanghai (1,088m) and the Rusky Bridge in Vladivostok (1,104m). At the time, the design was cutting edge and the technical challenges to be managed were significant. These included construction of the main deck — 73m above the entrance to Hong Kong’s main container terminal — in an area exposed to severe typhoon risk; construction of the geometrically complex temporarily prestressed reinforced concrete backspans; fabrication and erection of the 53m wide aerodynamic twin girder deck segments to tight geometrical tolerances; construction and erection of the 295m tall composite towers comprising carbon steel anchor boxes, architecturally-finished stainless steel skins which act as permanent formwork and reinforced concrete; and final stressing of the 690m long stay cable.
Contract Dispute Consultants acted for the contractor managing the complete commercial claims function. CDC’s role included identifying claims, preparing claim documents, updating contractual correspondence, advising the Contractor on contractual and commercial issues, managing the legal teams and reporting to the Joint Venture board on commercial and dispute issues.
During the course of the works, CDC handled a significant mediation with the Employer on extension of time and additional cost issues. CDC managed the legal and claims teams and advocated for the Contractor in the mediation hearings. The mediation resulted in a supplemental agreement for the Contractor incorporating a nine-month EOT and a significant additional payment.
CDC also managed a mediation for the Contractor against a supplier arising out of an industrial accident which had caused a major delay to the project. CDC advised the Joint Venture on strategy in relation to the progress of the mediation, advocated for the JV in the mediation and undertook the negotiations with the suppliers’ PI insurers. The dispute was successfully resolved within the mediation hearing.
Following substantial completion, CDC continued with their role on the project. CDC advised the JV on an arbitration in relation to a method of measurement dispute which resulted in a multi-million dollar award in the Contractor’s favour. CDC subsequently provided litigation support in appeal proceedings through the Hong Kong High Court, Court of Appeal and Court of Final Appeal.
CDC also advised the JV in relation to disputes with regard to further measurement issues, valuation of variations, technical, EOT and prolongation claims. These disputes were prepared for arbitration with CDC providing statement of claim drafting, delay analysis and quantum preparation services. CDC also managed the legal teams and expert witnesses and reported on the dispute progress to the JV board. CDC also advised the JV on issues relating to outstanding works, defects and completion obligations and subcontract disputes.
