Have your say on CRL safety
 
Do you walk, cycle, drive or catch public transport near the City Rail Link (CRL) construction sites on Albert St or at Britomart Station? 
 
If so, CRL would like to hear about how safe you feel when you move around these sites and whether you think anything more can be done to improve safety.
 
Your feedback is welcomed via a short online survey

First Albert St tunnel box walls formed
 
At the southern end of CRL’s Albert St trench, the first section of tunnel box walls has been formed.
 
Contractor Connectus Joint Venture is moving progressively from Wyndham St to Customs St, concreting one section of tunnel box at a time.
 
The Albert St tunnels are being built in 29 sections, each 12 metres long and requiring 330 m3 of concrete. Steel reinforcing bars are tied together prior to the concrete being poured to form the structure of the tunnel. There is a total of 81 tonnes of steel reinforcing used for each tunnel box section.
 
At the two viewing platforms, at Wyndham and Swanson Sts, you can now observe base slab and concrete wall formation, excavation, wall shotcreting and steel strut and waler installation.
 
By the end of June, you will be able to see the first complete section of Albert St tunnel box from the Wyndham St pedestrian bridge.
 
Connectus has now completed 65% of the trench excavation.

Secant piling work completed
 
Seventy secant piles have been installed across Lower Queen St as part of CRL works to link excavations under Britomart Station with those at Precinct Properties’ Commercial Bay development.
 
Made of reinforced concrete, secant piles lock together for strength and to control any groundwater ingress into the CRL tunnel excavation..
 
 
 
Underpinning frames take weight of heritage building
 
Before excavation of CRL rail tunnels can begin under Britomart’s Chief Post Office (CPO) building and across Lower Queen St, the weight of the CPO needs to be transferred onto a series of structural steel underpinning frames.
 
Contractor Downer Soletanche Bachy Joint Venture has been busy for many months, carefully preparing the heritage-listed building for the load transfers.
 
The first of the CPO’s 12 load transfers was completed this month. Once they are all completed, CRL can start safely excavating the rail tunnels under the CPO and Lower Queen St to join the tunnels that are being built under Precinct Properties’ Commercial Bay development.
 
If you’re interested in the technical detail of the underpinning works, we’ve got a page devoted to it on our website.

Buildings demolished ahead of stormwater diversion
 
Two CRL-owned buildings have been demolished in Mt Eden this month, ahead of work to divert a 400-metre section of stormwater main that lies in the way of the future CRL tunnels.
 
The former apartments at 26 Mt Eden Rd were demolished first, followed by the former Hyde Group building on the corner of Ruru and Nikau Sts last week.
 
Once the demolition sites are cleared, contractor March Bessac Joint Venture can start digging shafts at Water and Ruru Sts, where the micro tunnel boring machine that will install the replacement stormwater line will be launched and received. A third shaft at Mt Eden Rd will provide future access to the watermain via a manhole.
 
The stormwater diversion is expected to be completed by autumn 2019.

CRL to make key improvements to Ōtāhuhu Station and The Strand
 
Key improvements will be made to the rail network at The Strand (Parnell) and Ōtāhuhu Station as part of the CRL works.
 
At The Strand, CRL will deliver a new crossover connection, allowing trains to cross from one track to another. This will enable trains to more efficiently access The Strand stabling facility, where they can be held off the main network until they are required at peak travel times.
 
At Ōtāhuhu, CRL will be fitting out a third platform, adding a facility for operational staff and building a new track to allow for a new passenger rail service to run between the west and Otahuhu.
 
City Rail Link Limited (CRLL) is working with Auckland Transport and KiwiRail on delivery options and timing for these future works.
