Access to the faces was afforded by use of mobile elevating work platforms.
With the ground consisting of weathered mudstone augers were used for drilling to install the soil nails, once completed, some 70 tonnes of sprayed concrete was applied across the faces. This had the effect of smoothing the face and filling any small voids present after drilling.
For the finish, a bespoke 1200sqm gabion facing was installed across the whole face.
On face value this did look like a straightforward contract, however the site was incredibly congested as the various subcontractors were being pushed to complete ahead of schedule. To achieve this CAN worked day and night, whilst also remaining flexible to changing demands and programmes to work around other subcontractors.
