UK Power Networks required a new tunnel to improve power distribution in the Willesden/Neasden area of London. J .Murphy & Sons were awarded the contract the scheme and they chose Rorcon Limited as their preferred supplier to provide the specialist personnel to build the subsurface elements of the scheme. The underground works consisted of 3 shafts to depths of 28m, constructed in a combination of PC Segmental Linings and SCL, plus a total of 1.9KM of tunnel in 2.84 and 2.44 PC linings. The works were successfully completed ahead of programme and below budget.
