The largest transport infrastructure project ever undertaken in New Zealand is the City Rail Link (CRL) – a 3.45km twin tunnel rail link beneath Auckland's city centre.
An underground two-way through station that better connects the Auckland rail network. Doubling its rail capacity to cope with the forecast 54,000 passengers an hour at peak times, expected by 2035.
The CRL rail link is 42 metres below the city centre and transforms downtown Britomart Transport Centre from a dead-end station to a through station.
Tunnelling and station works were delivered by Link Alliance, a consortium of seven companies including Downer NZ, Vinci Construction Grands Projets S.A.S and AECOM NZ Ltd. Construction of the $4.419 billion rail link is due for completion in late 2024 – the handover date to operators, Auckland Transport.
Project engineers sought suppliers of reliable and efficient central chiller units to cool the critical infrastructure required to keep the underground rail network operational.
Project HVAC supplied the City Rail Link project with three central air-cooled chillers, controlled to work as one system through sophisticated AI automation.
All of which was implemented by the Project HVAC engineering team.
Project HVAC worked closely with contractors and consulting engineers during the design, supply, installation and commissioning of the central chiller units. Including the commissioning of intelligent Ecoshare software.
Project HVAC’s central chiller units solution plays an important role in protecting critical rail network infrastructure. Supplying chilled air to electrical junction boxes and critical operations which keep the trains running. An ideal mission-critical climate control solution for a unique and unprecedented transport infrastructure project.
