The work
Cliff Road involved the cliff top remediation of a large slip spanning a property in Auckland's Torbay.
Earth Stability was approached to provide a full design and build solution including initial consultation, site investigation, detailed design, obtaining the necessary consents, completing all works onsite and obtaining a code of compliance on completion of the works.
The project required the installation of 250m² of Maccaferri Macmat R erosion matting and rock fall mesh secured with 54 drilled and grouted galvanised and epoxy coated ground anchors.
The site was located within the coastal foreshore yard and was zoned a site of 'geological significance' under the newly proposed Auckland unitary plan. It also shared its border with a regional park and a fishing reserve. As a consequence of these three factors, a specific methodology needed to be adopted which would prevent damage to the highly sensitive environment and which would also exceed all Council requirements for working within each of the zones.
In addition, all works were completed over the peak of summer; consequently a requirement of the project was that it was completed with zero delays and zero disruption or impact to the large volumes of public visiting Long Bay and its surrounding beaches. These requirements were successfully met. Work was completed on time and to budget.
