The civil component of a 33kV underground feeder project for a NSW Rail Alliance has been completed by trenchless technology contractor UEA in Western Sydney.

UEA commenced construction of the 33kV feeder project in late August 2013 and completed the works in January 2014. The project involved the underground installation of 33kV cables over 4km between two existing sub stations.

Key components of the project included:

  • 2 x HDD creek crossings of Greystanes Creek which forms part of the Upper Parramatta River Catchment
  • Excavation and installation of 3.5km of 4 way 150mm HD electrical conduits backfilled with stabilised sand through busy residential streets in Blacktown and Holroyd Municipal Councils
  • Installation of 6 no. 25 tonne x 5m long pre cast joint bays.
  • Haul and terminate 12km of 33kV XLPE HV electrical cable
  • 4.5kms of fibre optical cable install including terminations in both substations  

This Rail Alliance involves the NSW State Government and a number of recognised construction companies working as one team to deliver a substantial portfolio (over $ 1 billion) of infrastructure work across Sydney’s local rail network. The range of work to be delivered by the Alliance includes the upgrade and re-energising of rail signalling and power systems to accommodate the introduction of the new Waratah trains including the upgrading and construction of new substations and associated feeders.
