  • due to the operating environment, working with the rail infrastructure provider, KiwiRail, to ensure the practicality and acceptability of proposed work methodologies, possessions and continued operation etc
  • maintaining safe operational capability for continued passenger and freight services
  • undertaking works in accordance with a block of line process to be agreed with Auckland Transport and KiwiRail.

C6 Mt Eden Stormwater Relocation

C6 will be procured as a lump sum, construct only contract based on New Zealand standard conditions of contract.

The C6 work package has been identified to divert trunk utility services in advance of the C3 and C5 work packages. The scope of works includes the construction of a 1.95m diameter pipeline at depth below ground level replacing the existing pipeline length on a new alignment over approximately 420m between Water Street carpark and Ruru/Nikau street intersection in Mount Eden. The key elements of the C6 work package include:

  • boring and thrusting a new pipeline at depth on curved lines through a wide range of material with accurate level tolerances
  • demolition of two buildings
  • excavation and construction of three permanent access shafts at Water Street, Ruru/Nikau Street and near Road
  • joining of the new pipeline to the existing pipeline by cutting-in at both ends
  • minor utility relocations, vehicle access and retaining wall construction and relocating an overhead traction power gantry on the rail corridor.

C7 Systems, Integration, Testing and Commissioning (Systems ITC)

C7 will be procured using an Early Contractor Involvement (ECI) model engagement through a bespoke ECI agreement, with the design and installation work carried out under a form of D&C contract, and commissioning work carried out under a work package/management fee basis.

Works include provision of trackslab, track, overhead line, signalling (control software and systems and interlockings to be provided by CRLL), control systems, tunnel ventilation, fire strategy and communications systems, control room fit-out and building work, and trackside auxiliaries. Rail systems to be installed from the existing operational railway to the east of Britomart, through Britomart Station, C1, C2 and DSC, the new station and tunnels (C3), and to the Western Line (C5).

Works also include responsibility for Operational Readiness. Once construction work has been completed and individual systems have been tested and commissioned, the system needs to be commissioned into service. This will include a trial running period, equipment testing and commissioning, driver training, test train running and operating/maintenance manual updating. Key stakeholders will include construction contractors, the train operator (currently Transdev), KiwiRail as owner and network operator, AT and CAF (the train supplier).
