Phi Group nets rock job

WHEN SCOTTISH Power decided to install a new sub-station in the middle of Edinburgh, within sight of the castle, it soon realised it had a problem. Being next to an exposed rock face, loose rocks were likely to fall on the station and damage it.

Rather than run the risk of destruction, the utility company appointed Phi Group to solve the problem by supplying and installing rock netting. The contractor drilled bolts into the rock face and attached continuous rolls of triple twisted mesh wired together to form a curtain. It will control the fall of loose rock, stabilise the rock face and encourage vegetation.

An area 11m high and 16m wide was covered during the last week of October with the project being completed inside a week.

Phi Group was appointed on a main contractor basis and was responsible for health and safety, organising site security and welfare facilities for site workers. Because the site is next to the railway line into Waverley Station, the works also had to be agreed with Railtrack.
