Albert St milestone: One step closer to completion

Albert St milestone: One step closer to completion


The re-instatement of Albert Street is one step closer as the City Rail Link (CRL) reaches another significant delivery milestone.

The project has started the backfilling of the trench which runs directly underneath Auckland’s busy Albert Street.

City Rail Link CEO, Sean Sweeney, says the milestone marks the start of the last stage of the Albert Street works needed before the road can be re-instated and returned to road users and pedestrians – expected late 2020.

“Anyone who has walked, cycled or driven past the Albert Street site over the last three years will have seen just how much work is underway to get this complete.”

“The team has been working very hard to get to this point relocating services, piling, supporting and diverting utilities, bulk excavation and constructing the tunnel box itself,” he says.

Backfilling of the trench will take until mid-2019 to complete and a total of 50,000m3 of materials will be used to fill it. That’s the equivalent of 20 Olympic-size swimming pools.

The material will be a mixture of crushed concrete, crushed rock, sand and flowable fill.

People using Albert Street will see an excavator sitting on the construction deck moving materials down onto the roof. The project team will then use small diggers to spread the backfill within the trench.

Mr Sweeney said that the project was grateful for the support of those who work on, live on and travel along Albert Street.

“Building New Zealand’s largest transport project in the middle of a built-up city is no small task and it is not without its impacts.”

“We’re grateful for the patience and understanding of our neighbours as we work to complete the project as quickly as possible,” he says.

The Albert Street works are being completed by Connectus - the McConnell Dowell and Downer Joint Venture delivering the C2 contract.

Last week, the project marked another major milestone on the C1 contract in Queen St with tunnel excavation at Britomart (the former Chief Post Office building) now proceeding at full steam.

The contractors working on that contract, Downer NZ and Soletanche Bachy JV, completed the weight transfer of the 106-year-old Category 1-listed heritage building onto a series of underpinning frames, which will protect it from damage while City Rail Link infrastructure is built underneath.
