Milestones 2017

Milestones 2017

Here are the big milestones in 2017:

 

Concrete poured for tunnel box

 08 December 2017

The first concrete has been poured for the CRL tunnel box in Albert Street.

Albert_St_concrete_pour_12_December_2017_web.jpg

Work started on December 21st 2015. It's taken the workers approximately 501,000 hours to get to this point.

So far, 30,000 cubic metres of soil and rock have been removed and filled up a double trailer-truck 1,866 times.

It’s also required about 8km of utility piping to be moved or suspended above the trench, and the main stormwater line two metres in diameter to be broken out and re-bored approximately ten metres sideways to the east. This is the reason a new 516 metre stormwater pipe was installed from Wellesley to Swanson Streets.

This first concrete pour was in the section beside the Auckland District Court and the Wyndham Street viewing platform at a depth of 18 metres.

The pour took almost 30 cubic metres of concrete pumped through about 56 metres of concrete hose all the way down to the base of the excavation. The job took around four hours from start to finish.

This first concrete pour is the “blinding layer” to form a flat and smooth layer for the next layer above it, which is the waterproofing membrane.

18-metre depth reached in Albert Street trench

29 November 2017

The Albert Street trench has reached its full 18-metre depth near Wyndham Street.

Contractor Connectus is now removing the 100-year-old stormwater pipe at the base of the trench before it can start building the CRL tunnel box at the southern end of the trench.

The redundant stormwater pipe will be unearthed at shallower depths as the evacuation moves north.

At the Customs Street intersection, the pipe is at a depth of only eight metres. The old pipe and a pumping chamber must be removed as they are in the way of the future CRL rail tunnels.

The current depth of the remainder of the trench varies between 3.5 to six metres but will all be evacuated from between 18 and 13 metres from south to north.

First concrete poured

23 July 2017

The first two concrete base slabs for the CRL twin-tunnels have been laid on Lower Queen Street.

The 700mm-thick concrete slabs are the first eight metres of CRL tunnel box floor to be poured out of the total 3.45km length of tunnel to be constructed.

Located under the Lower Queen Street walkway, adjacent to the Zurich building, these tunnel stubs will eventually connect to sections of tunnel from Britomart Station and Albert Street.

The slabs are protected by a high-tech water-proofing system to keep saltwater out, as they’re sitting about 13 metres below sea level.

In about a week, construction will start on the walls for this short section of tunnel. When a roof is eventually placed over the top in few month’s time, the result will be the first completed section of tunnel box for the project.

Bulk excavation work starts 

17 July 2017

Bulk excavation work has started for the cut and cover rail tunnels under Albert Street.

The excavation involves digging 18 metres (about five storeys) at the deepest (southern) point, using long-reach excavators above ground and smaller machinery inside the reinforced trench.

This represents about 10% of the 3.45km length of the twin-tunnel underground rail link,

The tunnels will then be constructed with a cast concrete floor, walls and roof before the trench is backfilled.

Steven Joyce told the ceremony: “Today’s signing is the next milestone in this important addition to Auckland’s public transport system. Auckland’s population predicted to grow by more than 700,000 people over the next 30 years, the CRL will play an important role in getting people in and out of the city with ease."

“Once complete, the CRL will fundamentally change the way people get around central Auckland and demonstrates the Government’s is commitment to Auckland and its Public Transport systems."

“CRL is Auckland’s top new transport priority. It will double the capacity of the whole existing rail network and provide significant travel time savings for commuters,” Mr Bridges says.

“The Crown and Auckland Council have signed agreements transferring the project to CRLL, formalising their partnership to jointly fund and oversee it through to completion,” Mr Joyce says.

“Under the leadership of Sir Brian Roche as Chair, CRLL will drive delivery of this complex project.”

KiwiRail, the state-owned enterprise responsible for all rail operations, has a formal role in ensuring the CRL's interoperability with the wider rail network and the services, such as freight, that it provides.

Stormwater pipe replacement completed

21 July 2017

The replacement stormwater pipe along Albert Street has been completed so the shafts that received the tunnel boring machines are being sealed and backfilled.

This will allow the hoardings and construction sites to be removed from Swanson and Wellesley Streets.

  INSPECTION: Workers inspect the shaft at the end of the new stormwater shaft under Wellesley Street

First tranche of City Rail Link funding

25 May 2017

Budget 2017 provides $436 million of new capital for Auckland’s City Rail Link (CRL), as the first tranche of the Government’s investment in this critical transport project for Auckland, Transport Minister Simon Bridges says.

“The Government announced in 2016 that it would support accelerating the delivery of the CRL to help address Auckland’s transport needs by committing to fund half of the expected $2.8 billion to $3.4 billion cost,” Mr Bridges says.

“The CRL is a game-changer for central Auckland and this funding demonstrates the Government’s commitment to Auckland and its public transport systems."

CRL wins Sustainability Project of the Year

3 May 2017

The CRL project won Sustainability Project of the Year at the EY New Zealand Procurement Excellence Awards.

  AWARD: CRL Project Director Chris Meale and Principal Sustainability Advisor Liz Root with the award

AWARD: CRL Project Director Chris Meale and Principal Sustainability Advisor Liz Root with the award

Judges said the CRL, New Zealand’s largest and most complex infrastructure project, “has been designed to the highest sustainability standards, standards unprecedented in New Zealand, with the design being recognised as ‘leading’ by the Infrastructure Sustainability Council of Australasia”.

Judges added: “The challenge to the team was to develop and embed these standards at the procurement stage across a project comprising eight different contracts. Taking learnings from the first contracting processes and expanding traditional notions of environmentally friendly outcomes to consider long-term social outcomes, we have no doubt that under the guidance of their procurement team with a focus on sustainability design, the CRL will be constructed and managed to the highest standards.”

The other finalists in the category were Air New Zealand and NZ Transport Agency.

Albert Street piling works completed

13 April 2017

The City Rail Link project has reached another milestone, with the last of 362 piles dug on Albert Street, between Customs Street and Wyndham Street.

‘Gomer’ - the nine-storey-high piling rig affectionately named after 1960s TV character Gomer Pyle - began piling in September last year. Each pile was drilled to a depth of 20 metres and filled with reinforced concrete, which will support the trench walls within which the CRL’s twin tunnels will be constructed.

Connectus, the project’s contractor, is now forming the concrete capping beams which will be placed on top of the piles to tie them together. Steel I beams will then span the width of the trench to brace the piles. This marks the start of construction of the ‘cut and cover’ tunnels across Customs Street and up Albert Street to Wyndham Street.

  FINISHED: Gomer’s last pile on the corner of Albert and Customs Street

FINISHED: Gomer’s last pile on the corner of Albert and Customs Street

The cut and cover methodology is being used in this part of the project due to the geology, shallow position of the tunnel and proximity of underground utilities. It involves the excavation of a deep trench between the rows of piles and construction of the tunnel structure (essentially a concrete box), after which the trench will be backfilled and the road reinstated. This work is due to be completed in late 2018.

Last week, the tunnel boring machine (TBM) simultaneously excavating and installing a new stormwater main 18 metres under Albert Street, finished its 500-metre journey between Swanson and Wellesley Streets.

Largest City Rail Link tender process starts

2 February 2017

The largest component of the City Rail Link (CRL) project – the construction of the tunnels and new stations - took a major step forward today with the release of its first tender documents to the industry.

The project is picking up speed with Expressions of Interest sought only a fortnight ago for the design, procurement, installation and commissioning of all tunnel track work and rail systems between Britomart Station and the Western Line at Mt Eden.

There will be two new stations as part of the build of the underground rail line linking Britomart with the existing western line near Mt Eden. The new stations will be near Aotea Square with entrances at Wellesley and Victoria Streets and a station in Mercury Lane, just off Karangahape Road. The present Mount Eden train station will be extended and redeveloped.

Tender documents sent out today are for the tunnel and station works that involve:

  • Aotea Station: Cut and cover construction of a 15m-deep, 300m-long underground station and plant room box, including platforms, lifts and escalators to street level, plant rooms housing station and tunnel equipment, full station fit-out and entrances at either end at Victoria and Wellesley Streets
  • Karangahape Road Station: Mined construction of a 32m-deep underground station, including platform tubes and 150m-long platforms, lifts and inclined escalator to street level, plant rooms housing station and tunnel equipment within two shafts, full station fit-out, entrance at Mercury Lane and provision for a future entrance at Beresford Square
  • Tunnels: Twin-bored tunnel construction (circa 7m diameter) between the Mt Eden station and the southern end of Aotea Station
  • The provision of maintenance services for the new stations.

Expressions of Interest sought

19 January 2017

Expressions of Interest are being sought for the design, procurement, installation and commissioning of all tunnel track work and rail systems between Britomart Station and the Western Line at Mt Eden. The work involves the provisioning of track slab, track, overhead line, signalling, control systems, tunnel ventilation, fire strategy and communications system.

The successful contractor will be responsible for the integration of the systems with the existing operations at Britomart and Mt Eden and the new tunnels and stations being built for the CRL. The documents, the first to be released to build the project past its current Britomart and Albert street sites, have been prepared as a result of the agreement between the Government and Auckland Council to jointly fund the project.

The C7 systems package will be procured using an Early Contractor Involvement (ECI) model followed by a Design and Construct contract.
