The balance cantilever bridge is the preferred choice of bridge when it is required to span between 50m and 200m. The balanced cantilever is a type of prestressed box girder bridge, whereby it is built incrementally segment by segment while maintaining stability during construction. The bridge construction begins at the piers and extends outwards in a balanced manner on both sides. The segments are prestressed prior to the construction of the subsequent segment.

The form traveller is essentially the travelling temporary formwork that fixes itself securely to the already constructed portion of the balance cantilever bridge and then provides the mould for the bridge and the working platform for the construction activity. Once each segment is constructed, the form traveller would travel forward to construct the next segment. Subsequently, once the balanced cantilever reaches the middle of the main span, the stitching segment shall be constructed to connect the two halves and unite them into a continuous span.

The form traveller method is the preferred construction method, allowing for longer and wider spans to be built using less materials than other construction methods. The form traveller also allows for building spans over deep valleys, waterways and roads where accessibility is an issue.

In this event, chartered engineer Kok Waihung will explain and share his experience constructing a balanced cantilever bridge using form traveller and why it is the preferred choice of bridge construction when it is required to span between 50m and 200m. He will guide you through the construction process and how it is built incrementally in segments while maintaining stability during construction. There will be an opportunity for attendees to ask questions and network.
