Case Study: City Rail Link Ltd (CRLL) C3 Contract, Auckland NZ

City Rail Link is a game-changer for Auckland. It’s the largest transport infrastructure project ever to be undertaken in New Zealand. It allows the rail network to at least double rail capacity, with growth statistics suggesting that by 2035, CRL stations will need to cope with 54,000 passengers an hour at peak travel times.

Overview of Works:

City Rail Link (CRL) is the largest transport infrastructure project ever to be undertaken in New Zealand. CRL is a 3.45km twin-tunnel underground rail link up to 42 metres below ground level, linking Mt Eden Station, to uptown Karangahape Station, to the mid-town Aotea Station and then to the downtown Britomart Station.

The project transforms the downtown Britomart Transport Centre into a two-way through-station that better connects the Auckland rail network. Mount Eden Station is redeveloped, where the CRL connects with the North Auckland (Western Line) and new underground stations.

Asset Engineering Services works with design, construction, maintenance teams to develop a full integrated lifecycle solution for the City Rail Link (CRL) project.
