Dean’s Head Remediation - Christchurch, New Zealand

July 20, 2017
Aurecon’s Advanced Design Technologist Simon York discusses the unique, cutting-edge smart solution for the remediation of Deans Head, an earthquake-damaged cliff and landslide on the Port Hills of Christchurch, New Zealand. _______________________________________________________________ So, one of the projects that I showed in AU this year was a site that came about because of the earthquakes that hit Christchurch about six years ago. It's a cliff site that used to have houses on it and, unfortunately, most of these houses were lost in the earthquake. Our role in the project is to monitor that site as the site is remediated, so that means a lot of materials can be removed from that site to reshape the whole site. It soon became obvious that AUVs were going to be a pretty powerful tool in this project. Initially there was a use of abseilers to inspect the cliff, especially after any aftershocks that happened. We were able to quickly implement use of UAVs though to perform those visual inspections and the use of reality capture tools such as Recap and Remake from Autodesk, soon became really powerful to be able to use to capture photos from the UAVs and then run those through to create models of the site. What are the benefits of this technology? So much time saved in that process, also just the accuracy – the ability to have a real representation, a 3D model of that site, on a weekly basis so we can now go back over the last six months and actually see where things have changed the entire time. I've been trying to promote throughout the business, the use of reality capture tools on every project, not just open lands type projects. I see it as being hugely valuable for building services and building structures. The ability to capture the existing buildings and have that data available to you when you’re designing, but also in the construction process. So, why shouldn't we be scanning buildings weekly as they've been constructed so that we know what’s happened on the site week-to-week and see where the changes have happened. _______________________________________________________________ Read more at https://goo.gl/NjNG2x
