Following rockfall in 2015 Golder Associates undertook a design for rockfall mitigation measures to protect the road and residential properties below. The detailed rockfall analysis showed a requirement for protection from a 5000 kJ impact with a system height of 7 m.
In December 2016 CAN Geotechnical were awarded the project to complete phase 1 of the works, a 40 m long and 7 m high 5000 kJ rockfall barrier. We supplied a RXE-5000 barrier. To enable future works to be completed more easily and without deconstructing the existing fence, we provided a solution for the end post to alllow for this.
Over several years and many projects Geobrugg has worked with both Golders Associates and CAN Geotechncial and a good relationship has developed. This enabled all of the involved parties to work together to find a cost effective and buildable solution.
The ground conditions on the eastside catchments are well known and extremly difficut to work within. To enable the works to be completed CAN Geotechnical had to carry out lots of temporary works and to use enlarged concrete bases for the fence posts. Additionally CAN Geotechnical opted to terminate all ground anchors into reinforced concrete bases with wire rope eyes protruding for connection to Geobrugg U-brakes.
