The scope of the project is “face” renewal of all remaining legacy overhead line systems in the Wellington Electrified Area of KiwiRail’s network. “Face” means renewal of all elements of the system, support structures (poles and masts), wires and switches on an advancing work face.
The current system is fixed termination and overwhelmingly supported by life expiring wooden poles direct buried in the ground. The new system is already used on Wellington lines previously renewed 2008 – 2016. Its design is a development of that used in Sydney and Melbourne, balance weighted lines supported by galvanised steel masts with reinforced concrete foundations designed to current seismic standards.
KiwiRail will provide the Supplier with a “30% Gate” Design for the system. The Supplier scope includes preparation of construction or “shop” drawings – “70% Gate” – and the as built drawings at project close – “”100% Gate”. “Construction drawings” includes responsibility for developing and having approved all transitional overhead states.
The scope also includes the moving of feeder wires and all remaining aerial and existing signalling cabling into a dedicated underground duct (pipe) system, the Combined Services Route (CSR). Completing the existing CSR, three mostly buried ducts with appropriate pits and track crossings forms part of the scope. This ensures the new traction structures do not have to accommodate the signals power supply line carried by the current poles. It also reduces the chance of cable strikes and service disruption while building the new traction mast foundations.
