Fortec Bridge 856 is located just south of Port Hedland. It has 19 spans with a total of 84 bearings that needed to be replaced in a tight 8 week contract period.
Main Roads Pilbara region utilised our expertise to replace the existing bridge bearings with new elastomeric bearings, including keeper plates.
Using our own synchronised hydraulic jacking system, we met the criteria set out by Main Roads by using four jacking points at each pier to simultaneous lift each pier / abutment in one operation.
To facilitate this process, we implemented a single lane closure traffic management plan, using temporary traffic lights to stop traffic during the synchronised lifting and lowering operations of the bridge.
Once the bridge was lifted, existing bearings and grout pads were removed and new grout pads poured using a high strength epoxy mortar which reached 50Mpa in two hours. This enabled the bridge to be lowered down onto the new bearings with minimal interruption to the flow of traffic.
