  • Pavements - Subbase, basecourse (recycled road base) asphalt & kerbing

The upgrade requirements also included the provision and installation of an anti-tunnelling slab that surrounded the functioning electrical substation. A new earth ring was installed along the perimeter of the fence for equipotential bonding.

Fencing was mounted with state-of-the-art thermal imaging cameras and vibration detection sensors calibrated to detect intrusion attempts and linked back to Western Power’s security team at their head office located on Wellington Street in the Perth CBD.

The fence was serviced by two new roads that were installed around it's footprint (one internal asphalt road and one external road-base finished road).
