McMahon Services has undertaken a number of individual upgrade projects for Flinders Ports over the last 12 months at the Flinders Adelaide Container Terminal, in Outer Harbor, Adelaide.
Flinders Ports are South Australia’s leading privately-owned port operator, operating seven ports throughout the State located at Port Adelaide, Port Lincoln, Port Pirie, Thevenard, Port Giles, Wallaroo and Klein Point.
McMahon Services have successfully completed a range of projects for Flinders Ports including crane rail repairs and Berth 29 hardstand repairs at the Osborne Port.
CRANE RAIL REPAIRS
This project involved the removal and replacement of 96 metres of existing crane rail which was showing symptoms of deterioration. Works needed to occur within a short window of opportunity between shipments.
The project scope included the removal of existing crane rail, hydro-excavation, setting up new base plates and installation of fixings, final levelling and placement of new 12 metres rail sections.
Once the new rail was laid, an infill of fast setting epoxy grout was installed in order to infill all voids around the underside of the crane rail. Once the epoxy had cured, placement and compaction of bitumen was finally undertaken.
BERTH 29 HARDSTAND REPAIRS
McMahon Services were contracted to undertake remedial hardstand repairs to approximately 20,000m2 of 90 tonne axle load rated hardstand, affected by subsidence at Berth 29.
The existing 25,000m2 hardstand construction was completed in September 2013 and has been subjected to the stacking and movement of containers continuously since that time. The heavy loads imposed have caused the subgrade zone between four and 15 metres below finished level to undergo secondary settlement. The subsidence has created issues with stormwater runoff, container stacking and vertical alignments.
Our specialist civil team undertook profiling of the top layers of asphalt and engineered to fill to nominal depths between 200mm to 250mm across the
site. We then placed and compacted clean engineered fill, two layers of asphalt, applied a spray primer and undertook final line marking.
Due to the fully operational Maritime Security Zone, McMahon Services required a collaborative approach in terms of shipping schedules, internal
road users and rail operations, all needing to remain priority throughout the works.
