Viaduct soars above Hong Kong skyline

The East Tsing Yi Viaduct in Hong Kong forms part of the new Route 8 project linking Sha Tin in the Eastern New Territories to Tsing Ma Bridge and Lantau. Work on the viaduct started in 2004 and is due for completion in 2008. The viaduct rises up to 60 m in height and has approximately 100 columns. RMD Kwikform designed and manufactured specialist steel formwork for the project. The column formwork was designed to pour up to 6m in height using the skip-and-crane method. In order to inspect the column construction, trailing platforms were designed to attach to the base of the formwork. Rapidshor stair towers were constructed to allow workers to reach the trailing platforms. Specialist formwork was also designed to construct 51 in situ pier segments. Special heavy-duty brackets and formwork were designed for casting the hammerheads and part of the portal beams. A significant investment was made in technical expertise to design and manufacture and formwork. During the design process, the availability and cost of support equipment had to be taken into account. (A)
