While most of Auckland was on holiday enjoying summer, the CRL team were busy locating and shifting services in preparation for the pipejack shafts going in on Swanson and Victoria Streets.

Working through layers of power and telecommunications services, they came across an unexpected piece of Auckland’s transport history – a section of the city’s old tramway network in Victoria Street West that connected back to Customs Street. “These services are always very dense at the corners of intersections where most are located, so you can never be certain what you’ll find underground,” says Mark Anderson, utilities engineer with the Connectus Consortium, undertaking the work. “Even though we used ground penetrating radar and searched

through the city’s service records, we didn’t expect to uncover the old tramway network.” Auckland’s electric trams ran from 1902 to 1956, when they were replaced by trolley buses. Running from downtown at the Waitemata Harbour and across to Onehunga on the Manukau Harbour, they were then the world’s only ‘coast to coast’ tramway system. The tramway section’s discovery on Victoria Street West meant an additional two weeks work, with the pipejack shaft hoardings now being installed late February. Shifting the services is made more complex by the need to ensure 900mm ground between the services and the roof of the future Aotea Station,
which will be just 1200mm from the surface. “It’s a very thin layer in which to fit everything,” says Anderson. The trenching needed at Swanson and Victoria Streets’ intersections with Albert Street was completed during the Christmas holiday period when traffic was quiet. Noise protection reduced the decibel level by 10 to 15 percent and noise monitoring will continue until work is finished. Now that people are returning to work, congestion is increasing on Victoria Street West where the next step is to widen the traffic carriageway on the south-side to accommodate a traffic lane in each direction.

Connectus Consortium Bob Mawdsley, engineering manager with the Connectus Consortium delivering Contract 2 of the City Rail Link, has a strong connection to the city’s rail network. Roll back the clock 15 years and he was managing the engineering on Britomart Station for Downer Engineering. In the early 2000s, Britomart was Auckland’s largest transport project ever, just as the CRL is today. Connectus, a joint venture of McConnell Dowell Construction and Hawkins Infrastructure Limited, are constructing the cut and cover tunnels under and along Albert St from Customs St to Wyndham St.
Newmarket Rail Station, a Hawkins Infrastructure project
“Between our two companies we have enormous expertise and capacity in civil engineering and building as well as micro-tunnelling,” says Bob. Bob has worked with the Well-Connected Alliance as Temporary Works Design Manager on the Waterview Connection motorway tunnels. The $1.4billion project tunnelled 4.8km of motorway underground using ‘Alice’, a 3,600 ton, 14.5 m diameter tunnel boring machine (TBM). The twin tunnels, at depths between 10m and 45m, are the largest diameter tunnels to be built in Australasia, and the 11th largest TBM used to date worldwide. McConnell Dowell also designed and constructed the Rosedale Waste Water Treatment Ocean Outfall, a 3km marine pipeline that discharges highly treated effluent into the Rangitoto Channel. Stretching from the treatment plant to Mairangi Bay, it runs deep beneath streets, parks, reserves and properties before going under the seabed 2.8km out into the channel. By simplifying and straightening the route for the western part of the outfall, McConnell Dowell enabled the land-based portion to be at least 25 metres underground, making it much less disruptive to Mairangi Bay residents and businesses.
Water sprays out of the Alice TBM as it breaks through into the tunnel portal.
Hawkins Infrastructure, and their company Harker Underground who are pipejacking the new stormwater line along Albert Street, are also leading experts in underground tunnelling, pipelines and shaft construction. Employing a range of specialist skills, from general earthworks and civil engineering to geotechnical engineering, their projects include the Auckland Rail Electrification Project, Newmarket Rail Station, and the Point Resolution Bridge crossing Tamaki Drive. “It’s great to see the City Rail Link becoming a reality, and to know the early works we are doing now will lay the essential foundation for its construction,” says Bob.

Signals go green for 2018 start
The Government has confirmed it intends to commit to funding for the City Rail Link. Auckland Council says this would allow construction of the main works to start in 2018. The Government’s
announcement has been driven by strong growth in rail patronage and the need to provide investment certainty for large-scale developments in the CBD.

Traffic delays ahead, make a travel plan
The Build is On campaign starts in February with extensive advertising in newspapers and radio, Google videos and a travel planning website. For motorists coming into the city, there’ll be road works, fewer on-street car parks and traffic flows will be slower. Now is the time to think smart about how to travel into the city. Consider carpooling, catching the bus, train or ferry, walking or cycling. You could even think about changing the hours you work, or work from home some days. AT has reconfigured bus routes and created new bus lanes, with more changes happening from April 17th when buses are moved out of Lower Queen Street in preparation for the CRL early works.
Auckland Bike Challenge – Fit in Feb Auckland workplaces are embracing a bike friendly Auckland and staff well-being with the Auckland Bike Challenge – a fun online event. 102 workplaces and more than 1,000 employees, are already on board with numbers rising daily. Open to all businesses in Auckland, it’s especially relevant to those affected by the CRL early works. Bike anytime, anywhere for at least 10 minutes during February and encourage others to do the same. Register at www.lovetoride.net/auckland (there’s a nifty app to download too). Check out the AT Great Rides for some inspiration or try an AT Summer Cycle Course.
Consider carpooling AT has made 15 car park spaces available to carpoolers on Level 8 of the Downtown Carpark. These spaces can be leased from AT for 10% less than a regular car park space if three or more people share the car (1 driver plus 2 passengers carpool) to the CBD. For more information about how to lease a carpool space visit www.at.govt.nz/carpoolspaces
