Next stop Te Wai Horotiu (Aotea) station! We're once again excited to get to work on New Zealand's largest transport infrastructure project, City Rail Link in Auckland. 

City Rail Link consists of twin 3.45km-long rail tunnels connecting downtown's Waitematā Station (Britomart) with a re-developed Maungawhau Station (Mt Eden). Two new underground stations will open up central city access along the route - Karanga a Hape (Karangahape) and Te Wai Horotiu (Aotea).

Ventia was chosen to deliver installation of systems associated with the electrical, communications and associated containment for the Te Wai Horotiu and Karanga a Hape stations as part of this project.

Additional services

Ventia is also providing additional professional services to the Link Alliance (the consortium delivering the main stations and tunnels for the City Rail Link project). This includes validation and verification of the Building Information Modeling (BIM) data associated with design. 

In addition, our team is responsible for the development of more than 1,200 work packages (known as Construction Work Packs, or CWPs). CWPs allow work to take place simultaneously across different project components, delivered by multiple teams, whilst ensuring alignment with installation specifications and quality assurance. 

Specific project controls have also been created for the installation across several disciplines at all stations. These will integrate all installation information into a single repository to include:

  • Health, Safety and Environment (HSE)
  • Productivity
  • Forward workload analysis in line with the programme
  • Resource forecasting

This information will allow City Link Alliance to view installation as it happens, and also provide an ongoing forecast of progress. 

Our team has previously undertaken specialist electrical work on the Waitematā (Britomart) station as part of this project. These works included the design, supply, installation, testing and commissioning.

There's more to Ventia…

Whilst much of the work has happened deep below the ground (up to 42 metres!), closer to the surface there's also plenty of action. Read on to see how Ventia's Telecommunications technicians kept businesses and residents connected to the internet while the projects below rumbled on.

Ventia is once again proud to be such an integral part of this amazing project.
