Batemans Bay bridge is replacing an existing steel lift bridge with a new precast segmental box girder bridge.
The $274 million project will build better connections in and around Batemans Bay for motorists, freight, river users, pedestrians and cyclists.
The new Batemans Bay bridge is built with prefabricated concrete elements installed from the piers towards the centre of the spans using the balanced cantilever method.
CaSE & Pike Design were engaged by John Holland to design the propping system to ensure the stability of the bridge during construction. The developed system is significant in its reduction to simplicity with a clear load path and elements that are simple to assemble, dismantle and re-use again on the next pier.
On successful completion of the new bridge, CaSE & Pike Design were also engaged by John Holland to assess the existing bridge during demolition one span at a time with the Design of sstrengthening to ensure the structural integrity of the bridge and load reversal and its foundation during its safe demolition. Our approach was to ensure a clear load path and sufficient robustness for a fit-for-purpose methodology developed closely with the John Holland team. And thoroughly reviewed as TfNSW asset.
