Bungy but not Jump

At world famous Bungy Jump Kawarau bridge, we installed 4 pipes under the bridge and brackets for a video system and a winch to bring the elastics back up, in good company of Xavier Fournier, Swiss guide. We had the thrill, and the work-out and even got paid for it 😉 . Photos courtesy of Rebecca Moar.

Glenorchy Landslide Testing

In an emergency response to the rockslide on the Glenorchy-Queenstown road in May 2010, we intervened during the week-end to test the rock stability so that it reopened the following Monday (read the Otago Daily time article).

The helicopter dropped us off above the cliff, we scaled all the loose rocks. Then, we anchored the large rock of concern, so that a digger could tug it from the road with a cable. When no movement was observed, it was deemed safe enough to reopen the road, once cleared.

Nevis Bluff: successful and in due time!

With our previous references on the same cliff, we succeeded on that tender. A team of four of us equipped in two weeks an access on that remote part of the Nevis Bluff. From the top first. Then with Heliworks delivery, we were able to built a rock fall barrier above the area to be worked on. The installation of 120m of ladders and steps bridges allowed Fulton Hogan team and ours to gain access every morning, using a double fixed line system. For the following 5 weeks: hand drilling, blasting, hand scaling and helicopter watersluicing composed the program. Thanks to our ability and abseiling  skills, Drilling & Abseil Services has been a successful part of the operations involving helicopters, heavy traffic management and work at height.
