Have your say on safety around CRL construction sites Do you walk, cycle, drive or use public transport near the City Rail Link (CRL) construction sites on Albert Street 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 While CRL contractors are focussed on delivering the project as quickly and efficiently as possible in a busy citycentre environment, safety remains the number one priority for their workers and the public, including walkers, cyclists, public transport users and motorists.

Here are some examples of safety features that have been implemented around our construction sites: • Perspex corners on pedestrian bridges to improve visibility for pedestrians and motorists • Barrier arms to protect pedestrians from construction vehicles and traffic • Workers managing all vehicle movements in and out of the site • CCTV to monitor our sites 24/7 • Painted red walkways and countdown timers to guide pedestrian movements

• Painted shared space road outside Britomart Station to create greater awareness of speed for motorists travelling through the narrow streets of Tyler and Galway • Traffic management on Tyler Street to help pedestrians, motorists and construction vehicles safely navigate the shared space.

• Well-lit pedestrian walkway along Lower Queen St CRL places high importance on maintaining walking routes through affected areas and ensuring local businesses continue to be accessible.

CRL staff walk the streets bordering the construction sites every day and regularly meet with Auckland Transport and Auckland Council to look for opportunities for improvement and to check whether people with disabilities can navigate the streets safely.

First Albert Street tunnel box walls formed

At the southern end of CRL’s Albert Street trench, the first section of tunnel box walls has been formed.

Contractor Connectus Joint Venture is moving progressively from Wyndham Street to Customs Street, concreting one section of tunnel box at a time.

The Albert Street 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.

Secant piling completed across Lower Queen St Seventy secant piles have been installed across Lower Queen Street 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 future CRL tunnel excavation.

At the two viewing platforms, at Wyndham and Swanson Streets, 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 Street tunnel box from the Wyndham Street pedestrian bridge.

Connectus has now completed 65% of the trench excavation as it moves towards the Customs Street intersection.

Underpinning frames to 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 Street, 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 Street to join the tunnels that are being built under the former Downtown Shopping Centre site (now 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.

March Bessac Joint Venture can start digging shafts at Water and Ruru Streets, where the micro tunnel boring machine that will install the replacement stormwater line will be launched and received.

The former apartments at 26 Mt Eden Road (pictured left) were demolished first, followed by the former Hyde Group building on the corner of Ruru and Nikau Streets last week.

A third shaft at Mt Eden Road will provide future access to the watermain via a manhole.

Once the demolition sites are cleared, contractor

The stormwater diversion is expected to be completed by autumn 2019. Find out more

CRL to make key improvements to Ōtāhuhu and The Strand

Concept design of the extra rail platform to be built at Otahuhu Station

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 Ōtāhuhu.

City Rail Link Limited (CRLL) is working with Auckland Transport and KiwiRail on delivery options and timing for these future works.

Take a look into Auckland’s past Politicians have been talking about an underground rail link for almost 100 years. Check out our history of public transport in Auckland with lots of cool historic photos.
