Project: Whitby Crescent, Mirangi Bay
Date: March 2017
Client: Private Client
ESL was engaged, through direct negotiation with the homeowners, to provide a full design and build solution, following a large landslip to their clifftop property in March 2017.
The completed project included the initial consultation, site investigation, detailed design, obtaining resource and building consents, carrying out the complete construction of the solution and obtaining a code of compliance upon completion of the works.
As part of the resource and building consent process in this project, arboricultural and ecological assessments were carried out, and a native planting plan was implemented.
Permanent works consisted of the following.
- 48 No. drilled and grouted soil nails requiring 230m of drilling.
- The existing slip was re-contoured by hand then covered with 150m² of turf reinforcement matting overlaid with double twist rock fall mesh.
- The works were finished off with a 200mm x 400mm 20m long reinforced concrete edge beam and new fencing.
- The completed repair was planted with native coastal species.
The site had extremely restricted access with access only down one side of the property and required us to work at a height of 25m over a vertical section of cliff above the sea below.
ESL’s highly skilled technical team and specialist ‘one of a kind’ restricted access plant enabled us to expertly carry out the works, placing paramount importance on the health and safety of employees and residents and the sensitive costal landscape.
A further challenge on this project, was that the Mirangi to Campbell’s Bay public walk way runs along the base of the site. Our methodology catered for this. Work was carried out safely, courteously and with great respect for those using this walkway. The walkway was therefore able to be safely enjoyed by the public throughout the duration of the works.
Work was completed on time, to budget and exceeded client’s expectations.
