RAMP FOUR REMEDIAL WORKS OVERWork to remove concrete from ramp four has been completed successfully. "Here at Waterview we are used to building things – not taking them apart. Deconstructing items is a totally different ball game" says North Construction Manager Lynne Makepeace.A total of 60 cubic metres was removed by hydro demolition from

a portal beam where ramp four passes over ramp three. During the removal programme our environmental team regularly monitored noise levels from our hydro work and installed noise absorbent curtains on-site to reduce noise.New concrete has been poured into the portal beam.

The last beam is placed on ramp two and the Great North Road interchange.

He came, he saw and after two and a half years, Dennis the gantry has conquered Waterview.In late May, the 90 metre long, 140 tonne bright yellow gantry completed constructing the Great North Road Interchange. The last of 277 super t concrete beams (weighing up to 70 tonnes) was lowered into position at the western tip of ramp two (northbound tunnel to SH16 westbound)."Dennis finished as it began – a faultless and precise performance combining engineering muscle and innovation to construct the interchange," says the Transport Agency's Project Delivery Manager Mieszko Iwaskow. Sliding backwards and forwards on rollers to fetch and lift the enormous beams which were up to 36 metres long, Dennis would then place them between columns which support the interchange. Dennis worked at night to allow our team to avoid larger traffic volumes, thus reducing any necessary safety closures of the motorway meaning less

disruption to drivers. During the day big Dennis rested above the live motorway below.  "The team working with Dennis has worked really hard in some pretty extreme weather conditions to deliver a quality programme of work safely – well done!" says Mieszko.Specially designed and built in Italy for the Waterview project, the gantry was named Dennis to honour one of our valued Well-Connected Alliance (WCA) team members who passed away from cancer. Shortly after completing the interchange, work began to deconstruct Dennis, which has been brought from the WCA.The Great North Road Interchange consists of four ramps that total 1.7kms in length to connect the Northwestern (SH16) and Southwestern (SH20) motorways and sit immediately adjacent of the tunnels.By connecting up the southwestern and northwestern motorways, the Waterview Connection will create a direct motorway link between the central business district and the Auckland International Airport.

Dennis conquers Waterview!

Final drive to completionThe Waterview Connection – New Zealand's largest and most ambitious roading project ever – is in its final drive to completion.Together with the patience and support of our neighbours we have been able to achieve many construction milestones over the past four years.With the project set to open for traffic in early 2017, your continued support is needed as there are a number of key works to complete over the coming months to ensure we finish faultlessly.

In some cases, it may require our team to work outside of our normal working hours (Monday to Friday, 7.30am – 6pm). When we do, we will continue to give our neighbours sufficient notice to inform them of our upcoming work."The successful completion of this project will truly change the way Auckland works as a city – not just for people in business but for all of us who call it home," says Project Alliance Manager, John Burden.

"The planned opening will have as big an impact on the way we travel around and through the city as the opening of the Auckland Harbour Bridge, almost 70 years ago," says John. "The change will be enormous and it deserves a fantastic outcome from this wonderful project of ours."See an aerial view of the key works in the Northern and Southern Work Areas that the Well-Connected Alliance need to complete as part of our final drive:

Join us at our next CLGThe Waterview Connection project's next Community Liaison Group (CLG) is coming up this month on 14 June.This is a regular three month forum for various stakeholder groups to meet with our construction team, urban designers and Auckland Council to listen, ask questions about the Waterview Connection project The June CLG starts at 6pm and is held in the training room at 150 Stoddard Road.

IN THE NEIGHBOURHOOD

Momentum builds on Waterview Shared PathMomentum is building on the Waterview Shared Path, with all site compounds set up for construction of its three bridges.Over the past two months our construction team has set up their site compounds for Alford Street Bridge (Oakley Esplanade and Unitec), Phyllis to Harbutt Boardwalk (Harbutt Reserve) and Soljak Place Bridge (1187b New North Road)."The landscape across the Waterview Shared Path project is rapidly changing," says Project Engineer Oscar Reindler."That's off the back of the solid start we've made to our work. We aim to carry on that momentum as we enter the winter months of our programme."The Soljak Place Bridge site compound was established in April, with work carried out on the north side of the railway tracks to clear vegetation and construct a haul road for bridge construction and beam delivery.A site has been set up at Harbutt Reserve, which includes an area for large vehicles/machines to turn, site offices and noise barriers. Neighbours continue to have access to the reserve playground and other open spaces in the reserve.With temporary piling set to finish for Alford Street Bridge in mid-June, our team will then move to our site compound at New North Road to begin similar work for the Soljak Place Bridge. Construction will then get underway on building the Alford Street Bridge.

ArchaeologyThe route of the Waterview Shared Path contains a number of sites of both cultural and archaeological significance. The shared path's alignment was altered to avoid disrupting the preservation of these historial sites. Our team is working closely with Heritage New Zealand, Iwi groups, Friends of Oakley Creek and our archaeologists to protect all historical sites in and around the project. The Alford Street Bridge is one of four areas where such sites have been identified and all works are done under an authority from Heritage NZ. Our team take a number of steps to protect these features by fencings them off and having archaeological and cultural experts involved to monitor the area.

Big numbers for NgararaA specially designed project innovation for the Waterview Connection project has racked up some big numbers inside the tunnels.Ngarara (Maori for reptiles) the drill gantry drilled 35,000 anchor holes inside the tunnel ceilings and walls over the past ten months. Once installed, the anchors will secure all the equipment to operate the tunnels safely: lights, deluge pipework, cable trays, CCTV cameras and signage."It's been an amazing journey through the tunnels – using Ngarara has exceeded all our expectations," says Justin Johnson the Project Engineer overseeing the mechanical fit out work."Initially we had planned to drill holes in tunnels' concrete rings at a rate of 10 per day – in the end we were getting up to about 22 rings per day."Weighing 25 tonnes, standing seven metres tall and stretching eight metres long, Ngarara operated by diesel powered hydraulic motors on wheels with electrical and air powered motors on the drill arch. Moving at a top speed of four km per hour inside the tunnels, a remote pendant is used to move it back and forth. Also its deck hovers five metres above ground to allow for tunnel traffic to pass below without delaying their work."Its shape, design, functionality and fabrication is an outstanding demonstration of New Zealand engineering," says Justin. "Without Ngarara we would be using scissor lifts for our work with people drilling holes manually which is inefficient, but above all, less safe more labour intensive and disruptive to other tunnel work," says Toby Parsons, a Site Engineer for the anchor drilling and support install. With 35,000 anchor holes done and dusted, Ngarara will be converted for electrical works – the arch removed, deck remaining – to install 4000 lights for the tunnels.

Cables connected on Hendon Footbridge The striking Hendon Footbridge completed a significant construction milestone mid-May with the successful installation and stressing of steels hangers or cables holding the concrete deck in place. "The installation of the cables completes the last structural milestone of the footbridge's construction," says the NZ Transport Agency's Highway Manager Brett Gliddon.A crane was used to install the 39 hangers between the sculptured arch and the deck which support 77 metres of the main span where it crosses the Southwestern Motorway. They have been tensioned to both support the bridge deck as well as restricting movement during

gusty winds."We've received lots of positive feedback from local people and our social media community who admire and appreciate the remarkable design of this landmark feature," Mr Gliddon says. "The beauty of the bridge's design will be equally matched by its easy access for people to explore new community facilities that we have built as part of the project."The 300 metre long footbridge will be used by walkers and cyclists to connect to the communities of Owairaka and New Windsor to access the southwestern shared path and new sports fields at Valonia Reserve and Barrymore Road.

WCA walk it out!The Well-Connected Alliance (WCA) got out and about to walk the Waikowhai walkway in May.Our Better Lives committee organised the long walk for our people to stretch their legs with family and friends (and a dog), taking in the great late autumn weather and spectacular views of the Manukau Harbour."This walk ties into our organisational goal of 'Better Lives" which aims to enrich the lives of people with strong relationships, good health and career identity,' says Stakeholder Liaison Manager – North Claire Donnelley."We regularly encourage our people to live better by eating healthy and keeping active. This was a fantastic way for the WCA to share and encourage those messages to their loved ones as well."

New facilities open at Valonia ReserveNew changing rooms and a volleyball court have been opened at Valonia Reserve.The opening of the community facilities marks the completed second stage of the Valonia Reserve upgrade.The upgrade is part of the NZ Transport Agency's Waterview Connection project with support from the Albert-Eden and Whau local boards.The changing rooms include three toilets, two separate change areas with showers and hand basins, and bench seating outside.There is also access to a bike rack and a car park for 50 vehicles.

"We're delighted to hand over modern new facilities to the community which will provide sports teams and residents alike with a great space to prepare, take a break and be active," Transport Agency's acting highway manager Mieszko Iwaskow says.Stage one of the upgrade included the construction of two sports fields, drainage, lights and sand-turf pitches.The final stage will be the construction of a half-size basketball court and skate park near Richardson Rd.This is expected to be completed by early 2017.

'World class' cross passages completeIt's the end of the road for our cross passages team at Waterview, but they hand over all the cross passages for their Mechanical and Electrical (M&E) installation, knowing they've done a 'world class' job."The workmanship demonstrated in the construction and finish of the cross passages is truly world class," says Cross Passage Project Engineer Alain Giauque.All permanent works to construct the cross passages are complete with fire doors installed. The mechanical and electrical team have moved in to install deluge piping in the main corridor of

the cross passage and tunnels services and operational gear inside its two rooms."They've been constructed with a 100 year design life which is great for the maintenance and operation of the tunnels when they open to the public."Construction of the 17 cross passages started in early 2014 with 16 built between the two tunnels and one in the Southern Ventilation Building.A cross passage is situated every 150 metres inside the tunnels and provide access for people to escape between the tunnels in the event of an emergency.
