Work here covers Wakefield Avenue from the intersection of Wakefield and Paisley Street in the south to Wakefield and Nayland Street in the north.

WakefieldsThe road is currently protected from geotechnical hazards by ballasted shipping containers. The shipping containers will be removed once the geotechnical works are completed. The road will return to its previous layout and this will improve safety for cyclists and drivers. Where we can, we will work on more than one site at the same time to get through the work as quickly as possible and reduce ongoing disruption for residents.

Geohazard mitigation

There is a cliff collapse risk at each end of the road, while the cliff at the northern end is at risk of mass movement (landslide). There is also a boulder roll risk from the bluffs at the southern end of the road. The solution for this area includes bunds, rock deconstruction and scaling. A bund is an embankment built out of rock or earth that is used to catch rocks that are falling down a slope. The structure can stop multiple rocks and can protect the infrastructure behind it from being hit by rocks. 

Scaling is the physical removal of individual loose and unstable rock from rock slopes. Light scaling is done using hand tools such as a crow bar or pick. Heavy scaling is done using mechanical equipment such as air bags or jacks. HEB Construction will be doing the work in this area. Works are underway on site and are expected to be completed in October 2016 (weather permitting).
