CAN Geotechnical returned to Gibraltar to extend the 5000kJ catch fencing we had previously installed in 2017. Working closely with the Government’s Engineer – Golders Associates, CAN assisted with value engineering the base design for an efficient and cost effective installation.
An A-Frame slope rig was employed to install the post base anchors, backstay anchors and lateral anchors. This ensured that each anchor was installed in the direction that the load was applied. The orientation of these was often not perpendicular to the slope and required precise manoeuvring and setting up of the slope rig.
The team managed the lifting operations of a crane positioned in the road to install the 7m high posts. Once the posts were installed, access to the top of the posts to assemble the cables and netting was by means of aid climbing. The extension equated to the 40 linear metres length of catch fencing, which was supplied by Geobrugg.
Various measures were taken to work safely around the numerous protected fauna and flora and poisonous species. The stone pine plants were fenced off in an exclusion zone and a combined effort was made to make sure works were completed before the barbary partridge nesting season began.
CAN completed the second phase of this project on time, safely and to budget.
