Microtunnelling on CRL reaches milestone

The first portion of microtunnelling has been completed on a new rail infrastructure project in Auckland, New Zealand.

The City Rail Link (CRL) will extend Auckland’s passenger rail system past Britomart to connect to the existing regional rail network at Mt Eden, and provide for an estimated population growth of 700,000 in the next 30 years.

CRL Project Director Chris Meale said a microtunnel boring machine (MTBM), which has been excavating and installing a new stormwater pipe under Albert St, had finished the first leg of its journey.

The MTBM was chosen for the project due to its safety benefits, as it kept workers out of the tunnel and provided a far greater level of control over the rate of excavation and the management of different ground conditions.

“What will be a highly efficient and reliable transport choice for Auckland is now visibly taking shape,” Mr Meale said.

 

The CRL has also released a tender for the design, procurement, installation and commissioning of all track tunnel work and rail systems between Britomart Station and the Western Line at Mt Eden.

It is currently seeking expressions of interest for the design, procurement, installation and commissioning of all track tunnel work and rail systems between Britomart Station and the Western Line at Mt Eden.

Tendered works include the construction of 7 m diameter twin tunnels running from Mt Eden station to the southern end of Aotea Station, via the Karangahape Road Station.

A station near Aotea Square will be built, with entrances at Wellesley and Victoria St, as well as a station in Mercury Ln, just off Karangahape Rd. The present Mount Eden train station will also be extended and redeveloped.

Construction works started in June 2016 and are expected to take five and a half years.
