In 2019, The Surveying Company was asked to provide accurate 3D data of the cliff faces of Bluff Hill for inspection and monitoring purposes. The 3D model enabled geotechnical engineers to identify problem areas make informed decisions without the need to physically be at the site.
A fly-through of the 3D model generated from drone data is shown below.
Recently an unstable rock was identified on the cliff face above Breakwater Road. The Surveying Company was asked by Napier City Council to provide aerial photography of the rock and surrounding area to get a better understanding of what was happening. Using a UAV was a far cheaper, easier and safer option than sending someone down the cliff face for a visual inspection.
While on site, the surveyor was able to generate a full 3D model of the rock and the surrounding area, from which measurements could be taken. This rock measured approximately 5m x 2m. The 3D model can be viewed here: https://cloud.pix4d.com/dataset/680631/model?shareToken=83fbb2cc-3003-4f06-b5e0-79fc7ace9d3a
The rock continued to be monitored over a period of a few weeks, with follow up photography captured to compare changes over time.
When the decision to bring the rock down was made, The Surveying Company was asked to document the process using a UAV capturing video and photography.

After a few hours of prep work, the rock was ready to be dislodged.
Without too much force, the rock was prised off the face using airbags, and fell to the road below.
The job was executed safely and professionally with input from The Port of Napier, NZTA, KiwiRail, Downer & Napier City Council.

We are very happy with the service provided by all of the people we have dealt with at The Surveying Company, thank you.
Nick Wakefield did a great job through a difficult time with COVID and everything that went with it. There were many delays with the project outside of Nick's control. A project that should have taken months took years, but Nick continued to steer the project and followed up when he could.
The level of service and expertise we received during our land subdivision using Nick and The Surveying Company was outstanding. Nick was always prompt, responsive to our many queries and fully supportive for us throughout the whole process. I would recommend Nick and The Surveying Company to anyone seeking this type of expertise and advice.
