Contractor completes City Rail Link tunnel box

The first 348 metres of the Auckland City Rail Link has been completed by contractors in New Zealand.

The Connectus joint venture of McConnell Dowell and Downer, have completed the tunnel from Wyndham Street through to Commercial Bay.

Since December 2015, the joint venture have installed 362 reinforced concrete piles around the future CRL twin tunnels and relocated the major stormwater pipe on Albert Street.

It has also strengthened the Orakei sewer main and relocated kilometres of stormwater, electrical, gas, sewerage and internet lines.

In total, 2500 tonnes of steel bar reinforcement have been tied together, and over 10,000 cubic metres of concrete have been poured which has meant bringing in over 1600 full concrete trucks just for the tunnel box formation.

City Rail Link’s Chief Executive, Dr Sean Sweeney acknowledges the work of the contractors, and the support from the local community.

“Construction like this in the middle of a city is never easy for anyone. The risks for workers that come from working in confined spaces, and the disruption for people living and working nearby but we have taken a big step towards building a project that will change the way people can travel around our city.”

The joint venture is now near to completing the removal of temporary ground support, relocating the services and backfilling the trench.

Albert Street will be fully reinstated starting mid-July.

It is intended that the first sections will be completed at the Wyndham-Albert Street intersection by the end of this year.
