Project Overview
Construction and installation of new berthing infrastructure for TasPorts, with hydro-demolition and concrete repairs to strengthen the existing wharf.
A single fender design was retrofitted at ten locations along the wharf. Each of the ten concrete fender blocks combined a precast panel tied into a heavily reinforced deck slab, and carries a cone fender and a 100 t bollard. Two standalone 100 t bollards were also fastened to 100 mm thick steel plate.
Temporary crane platforms, designed by BridgePro, allowed a 50 t crane to travel the full length of a wharf rated to only 4.6 t axle load. Lifts were sequenced to minimise crane movements.
Areas loaded during berthing were hydro-demolished and repaired with high-strength concrete repair material. Under-wharf work was carried out on night shifts to suit the tides, using semi-submerged, suspended and floating work platforms, while communication and vehicle management plans kept log export operations running.
Key figures: 10 concrete fender blocks, 100 t bollards, 50 t crane on a 4.6 t axle-load wharf. Design engineers: Burbury Consulting.
