Work Package descriptions
C3 Stations and Tunnels
The C3 Work Package will be procured using a design and construct model with a lump sum price based on a bespoke contract.
A portion of the bid costs for any unsuccessful shortlisted C3 bidder will be paid in return for any intellectual property rights and effort expended. The C3 Stations and Tunnels EOI Phase is nearing completion and will conclude with the shortlisting of two respondents to proceed to the RFT Phase.
This shortlisting is currently delayed by 3 months. A recent change in the scope between the C7 and C3 Packages has meant that tunnel ventilation and fire strategy are now within the C3 Package.
The works therefore now include:
Aotea Station – construction of a 15m-deep, 300m long cut-and-cover station, including platforms, lifts, escalators, rooms housing station and tunnel services equipment, entrances at Victoria and Wellesley Streets, building works, services, architectural finishes, utilities services diversions and connections and reinstatement of streets and foundations for an over site development over the Wellesley Street entrance.
Karangahape Station – construction of a 32m-deep mined underground station, including shafts, platforms, lifts, escalators, rooms housing station and tunnel services equipment, an entrance at Mercury Lane, provision for future entrance at Beresford Square, building works, services, architectural finishes utilities services diversions and connections and reinstatement of streets and foundations for an over site development over the Mercury lane entrance.
Tunnels – construction of two bored tunnels approximately 7 metres diameter between Mount Eden Station and Aotea Station, and a fully grade separated junction within mined caverns connecting with two cut-and-cover tunnels to form east and west facing connections to the existing North Auckland Line.
Mount Eden Station – construction of a new station to provide interchange between the CRL and the existing Western Line including a 7m deep open trench for the CRL platforms, concourse structures, lifts, escalators, rooms housing station and tunnel services equipment, an entrance at Ruru Street, building works, services, architectural finishes utilities services diversions, connections and reinstatement of streets, and foundations for over site developments.
Station Group Control Centre – structures, building works, services and architectural finishes for the Station Group Control Centre that will be fitted out by the C7 Alliance contractor.
Tunnel Ventilation System – fans, attenuators, ductwork, louvres and control systems for the tunnel ventilation system housed within the stations.
Fire Engineering – development and implementation of fire life safety strategy and the fire engineering brief for the new stations and all the CRL tunnels, design and construction of fire engineering systems within the new stations and tunnels.
Asset Management – provision of maintenance services for the three new stations.
C5 Western Line
The C5 Work Package has been amended to include only the civil elements of the Western Line, with the C7 Work Package now undertaking the rail systems elements. The contract model for the C5 Work Package is still being determined.
The work includes:
Western Line Connection – civils works required to connect the CRL main tunnels to the Western Line and comprise significant civil construction works with new road, rail and pedestrian bridges and retaining walls.
C6 Mt Eden Stormwater Relocation
C6 has been procured as a lump sum, construct only contract using the NZS 3910 form of contract and has been awarded to March / Bessac JV.
The C6 Work Package 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 Mt Eden 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 (Rail Systems Alliance)
C7 will be procured using an Alliance form of contract and will be a linewide rail systems package.
Works include provision of trackslab, track, overhead line, signalling (control software and systems and interlockings to be provided by CRLL), control systems, 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 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).
The C7 Work Package now also includes the scope of the previous Britomart East C9 Work Package to provide increased vertical pedestrian/passenger flows out of the east end of Britomart, as well as the scope of the Henderson and Newmarket sites.
C8 Wider Network Improvements (Otahuhu and Strand)
The scope of the C8 Work Package has been reduced to cover the Otahuhu and Strand sites. The works at Henderson and Newmarket have been re-allocated to the C7 Work Package. The C8 Work Package will now be delivered by KiwiRail and Auckland Transport.
The scope of the C8 Work Package includes:
Otahuhu Station rearrangement – introduction of the CRL timetable diverts many Western Line services away from Newmarket and South to give the significantly better West to Britomart service. A new service will be provided between Henderson and Otahuhu as a replacement. This project allows the operations of the purple route at Otahuhu.
Strand Crossover – The CRL timetable demands efficiency of all movements and the movements out of the Strand EMU storage depot are inefficient due to the extensive amount of ‘wrong way running’. This is resolved by the placement of this crossover.
C9 Britomart East
The scope of works for this package has been re-allocated to C7.
The CRL Industry Briefing was held on 29 November 2016. The briefing was well attended and focused on the procurement process, governance and technical aspects of the project. An information booklet was provided on the day to all attendees. See links below to the presentation slides and information booklets.
