Falling Rock Protection work for Volker Laser and AMEY.
February 2013 – As an alternative to Rock Anchoring and meshing the embankment, Condor has recently installed a Fence protection kit to stop moving rocks up to a maximum energy level of 100kJ. The specialist fence was supplied in kit form by Geobrugg and imported in from Switzerland.
Condor prepared the area by clearing the 200m long fence line and then installing anchors and concrete bases to support the fence posts. Hand scaling via a MEWP was also undertaken as part of the prepatory work. The fence was then installed and supported by anchor ropes tensioned to ensure the fence is fit for purpose and allowing for some flexibility in the event of any rock fall. In order to comply with the wishes of English Heritage and for presentation purposes the fence was given 3 coats of Metalguard paint.
The works were completed on schedule despite difficult weather conditions and to the client’s satisfaction.
