Wind Turbine Foundation Repair
Freyssinet were engaged to complete repair works to wind turbine foundations at a windfarm in South Australia.
Movement at the base of the wind turbines had been detected and the source of the movement was examined. Upon investigation it was determined that water ingress between the foundation and turbine interface had been exacerbating the movement and creating voids.
Freyssinet’s works involved stabilisation of the turbines through repairs to the foundations and prevention of future water ingress to the foundation-turbine interface.

Low Level Bridge Replacement Program
The Low Level Bridge Replacement Program consists of the replacement of seven (7) existing steel bridges on the BHP Newman Main Rail with new concrete culvert structures to ensure sustainable, safe operation of the railway and to consider future haul capacity expansion.
Due to the clients operating requirements, each bridge has to be replaced within a twelve (12) hour shutdown window. Each new concrete bridge is constructed offline approximately 10 meters adjacent to the existing bridge.
Freyssinet is engaged to lift and slide the existing bridge out of the rail alignment, and lift, slide and lower the new bridge into final position in the rail alignment with tight installation tolerances within a two (2) hour duration in order that the subsequent rail and finishing works could be completed on time.

With these defects found on the bridge, Brisbane City Council instructed the replacement of 40 units of bridge pot bearings and removal of concrete at the northern abutment to free up the articulation of the bridge.
