The Nowra Bridge is a road bridge that carries the Princes Highway over the Shoalhaven River in the Shoalhaven Council on the South Coast of New South Wales, Australia. The Bridge project will provide a new four lane bridge over the Shoalhaven River, upgraded intersections and additional lanes on the Princes Highway. The new bridge is a new, incrementally launched twin T-girder Bridge. Nowra Bridge foundations are four piles with a pile cap at flood level.
CaSE & Pike Design performed the construction engineering and temporary works design for the precast pile cap of approximately 70 tons. CaSE detailed the installation methodology, considering rubber ring to seal the water before grouting an underwater plug. The Project comprises of a number of features including, high flooding risk area, precast pile cap shell and in-situ infill pour, in- water installation of the pile cap shell and a pontoon moored to the pile cap platform for marine access. Interaction between client, permanent works designer, crane/transporter supplier and contractor was essential.
