Pukeahu National War Memorial Park and Arras Tunnel
Red steel poppies lining Arras Tunnel remind travellers on State Highway 1 through Wellington that they are in a memorial space below Pukeahu National War Memorial Park, the Government’s centrepiece WWI centenary project.
Both tunnel and park opened well in advance of their respective deadlines and hosted Anzac Day centenary commemorations on 25 April 2015 when 60,000 people gathered at dawn in the park to honour those who have served at war.
Arras Tunnel and Pukeahu Park in central Wellington were designed and constructed by the Memorial Park Alliance of NZ Transport Agency, Downer NZ, HEB Construction, Tonkin & Taylor and Aecom (formerly URS). The park concept was won through competition in 2008 by Wraight Athfield Landscape and Architecture and adapted in 2012 to include the tunnel - removing the state highway from the surface as it was in the original concept and integrating the tunnel into the park design.

The geology of the central Wellington site was such that unique engineering solutions were devised so the tunnel could withstand a 1-in-2500 year earthquake. The high seismicity of the site less than 2km from the active Wellington Fault and evidence of past lateral spread of the soils required a robust design for the tunnel which has 800mm thick walls and floor slab and a roof slab varying in thickness from 1200mm to 450mm.
A 300m long, 18m wide, 12m deep cut-and-cover trench was excavated to allow formation of the 130m tunnel - essentially a reinforced concrete box cast fully in situ with the floor, walls and roof cast in separate pours. Construction was facilitated by temporary retaining walls so the tunnel could be cast within.
Liquefaction buoyancy was addressed with ductile tension piles beneath the floor slab. Significant pile testing was undertaken to determine the most appropriate design after initial testing on straight shaft piles failed at 20% of the required design load. A belled-base pile was constructed using a custom-made belling tool and exceeded the design load requirements, allowing a reduction in number and length of piles.

The state highway through this area of Wellington west of the Basin Reserve and passing in front of the National War Memorial was formerly known as Buckle Street. That name now applies only to the access lane on the southern side of the park.
Before construction, the bend west from Sussex Street into Buckle Street was narrow with 2 lanes in one direction, a slight incline upwards and a substandard centreline radius of 22.5m. Traffic flows were 22,000 (2.8% heavy vehicles) and frequently queued back around the bend from traffic signals at the Tory Street intersection about 100m away.
Today the highway turning west from Sussex Street heads down a trench into the one-way Arras Tunnel, surfaces at Taranaki Street and carries on out of the capital city through the Terrace Tunnel. Tory Street no longer intersects the state highway and is a link road through the park. Traffic flows along SH1 through Arras Tunnel are predicted to be 30,500 by 2025 (2.8% heavy vehicles) equating to 25.2MESA.
Following construction, the 2-lane entry has improved in terms of curvature, super elevation and lane layout. It was a challenging design because of geometry restrictions, including retention of existing twin 33kV cables. The 3.5m lanes plus 1.0m margins have a super elevation at 5.0% around a 35.4m centreline radius.
The 2 lanes filter into 3 lanes through the tunnel and 4 lanes at the Taranaki Street intersection. The design speed throughout is 60kph with a posted limit of 50kph.
The pavement developed by MPA has a 40-year design life and used Polymer Modified Binders (PMB), resulting in a reduction in the overall pavement thickness from 240mm to 180mm.  The surfacing layer was AC14 using Melter Slag aggregate for durability.
For the future, the geometric design for the road into the tunnel can accommodate a future Basin connection, should a project proceed.

The tunnel specimen guide design included 4% grades into and out of the tunnel. Through accurate survey of the 1895-vintage 1.5m-high brick Tory Street sewer and careful design of the Tory Street minor road connection above the tunnel, the alignment was amended by lifting it 1.1m to clear the sewer.
This minor movement of the sag point and change to the entry grade of 2.8% provided a smoother alignment. Careful design enabled a reduction in roof slab thickness to 450mm - 708mm, which at the tightest point is only 200mm below the connecting road and footpath above.

Pukeahu National War Memorial Park above the tunnel consists of a series of boulevards and terraces - 300m-long and up to 70m-wide (21,000m²) - that extends the presence of the existing National War Memorial into the capital city.
The Australian War Memorial of red sandstone pillars opposite the New Zealand memorial is a tribute to the shared experiences of both our countries and is the first of the international memorials that will be integrated into the park.
The national significance of the park was recognised by the 60,000 who attended the Anzac Day dawn ceremony and the many thousands who visited throughout the day for subsequent ceremonies. At 5.00pm every evening for the next three years to 11 November 2018 - the end of the centenary of WWI – the Last Post bugle call will be heard across the park from the Tomb of the Unknown Warrior.

Member Profile - Richard Steel

Richard became a committee member of the New Zealand Chapter of the REAAA in May 2005 and subsequently became Treasurer and then Chairman from July 2007 until  April 2012.  He has been Hon Treasurer General for the parent body since September 2009 and became an Honorary Life Member of the Chapter in June 2012.

Richard grew up in the South East of England and attended university in Wales, graduating from University College Cardiff with a degree in Civil and Structural Engineering.   He then began a career in road engineering which has spanned more than 43 years.  His first employment was with Liverpool based consultancy Ward Ashcroft and Parkman which, through a number of corporate changes, has now become part of Mouchel.

He spent the first 10 years of his career with Ward Ashcroft and Parkman and gained the necessary training in design together with practical site experience to become a Member of the Institution of Civil Engineers in 1976.  His experience in the United Kingdom varied from design for a dual carriageway bypass scheme in North Wales, to construction experience on secondment to a contractor, firstly for a bonded road container depot in Liverpool and then a bypass scheme in Cheshire.

It was at this time that he also became involved in international assignments which took him to Algeria and Portugal, each for a number of months, and Nigeria for a period of 4 years from 1976 until 1980.  Richard considers the time in Nigeria had a major influence on his career and development as a person and provided opportunities and experiences that he has valued enormously.  Project work included consultancy design and construction supervision contracts for literally hundreds of kilometres of two lane sealed and asphalt surfaced state highway between Nigeria’s state capitals.  Learning how to work with and help to train Nigeria engineers was a new dimension and the camaraderie of the expatriate community led to lifelong friendships.  He also had the opportunity to travel to other parts of West Africa and after returning to the UK on leave on one occasion, he drove back to Nigeria, trans-Sahara, in his own Land Rover.

Richard returned to the UK for one year in 1980, based in Bristol before he was contacted by New Zealand consulting firm Beca Carter Hollings and Ferner Ltd (now Beca Ltd) about a possible position as a Senior Roading Engineer in Papua New Guinea which he took up in 1981 and he subsequently spent nearly 7 years in PNG.  That experience included being Co-Director of the PNG practice from 1982 and Richard well remembers Sir Ron Carter visiting PNG and expressing his expectations as; “Get Work – Get it Done – Get Paid”. 

Project experience in PNG included being Team Leader for a major Asian Development Bank funded highway improvement project; starting with a commission for a feasibility study for improvements to more than 300km of the national highway network and subsequently design and construction supervision commissions for several of the selected projects. 

The involvement in Asian Development Bank and World Bank projects in PNG then led to Richard moving to Auckland in 1989 to join Beca’s international division to secure and deliver a variety of roading projects in the Pacific, South East Asia, Tanzania and India.  Standout projects for Richard include a nationwide road inventory and 5 year maintenance plan for PNG; a provincial roads improvement project and writing strategic directions for the road sector in Laos; road improvement feasibility studies, detailed design and construction supervision in the north west of Tanzania near Lake Victoria; and individual staff consultancy assignments for the Asian Development Bank in Viet Nam and the Pacific.

When the market for international work started to change Richard transferred into Beca’s infrastructure group.  His project planning experience led to roles leading the preparation of a passenger transport network plan for Auckland and a similar project to help identify the desired rapid transit network modes and corridors in the south west of the Auckland metropolitan region.

More recently and in response to the changes in the road maintenance market in New Zealand Richard has played a leading role in Beca’s growth and development of its road asset management and maintenance support services.

Richard retired from full time employment with Beca earlier this year and he is enjoying having more time to indulge in his passions for golf and sailing; while also keeping the brain active as he continues his interest in the REAAA and in a number of project related roles including the Auckland Motorway Alliance.

Spreading the Journey Management Gospel
The value in the partnering between the Road Engineering Assn and NZ Transport Agency Journey Managers was highlighted at recent Journey Management and Network Outcomes Contract presentations.  It was a great opportunity to share the Journey Management gospel and show the benefits to our customers.

Presentations were held in Whangarei, Hamilton, Tauranga, Napier, Wellington and Christchurch, presenting to 280 attendees from across the contracting, consultants, and local authorities world.

Following the Christchurch presentation, one contractor commented he now understood why it was critical to timely feedback information to WTOC (Wellington Transport Operations Centre) and into the Treis messaging system with the latest, timely information – and photographs of what was happening on the highway. He now had a greater appreciation of how the information was used and how it helped improve the journeys for all travellers.
One of NZTA’s council partners commented on understanding why there is a need to better share, co-ordinate and collaborate what is happening in the summer works season. As a result, we can be reassured of providing an even better service for our customers – the true value of partnering up and keeping our stakeholders well-informed of what is happening with the NZ Transport Agency.

More than 70 roading engineers and contractors attended the presentation in Christchurch, which also included the latest on what is happening at the Christchurch Transport Operations Centre from Tresca Forrester and an overview of the new Network Outcome Contracts by Barry Stratton.

Across New Zealand great feedback was received from those who attended the presentations and highlighted the need for on-going opportunities to keep sharing the journey management story with others. Thanks to the Road Engineering Assn for coordinating the presentations.

NZTA 2016/17 Research Programme
The NZ Transport Agency is commencing the research round for 2016/17 by asking selected transport sector organisations for key high-level land transport challenges which research can assist to address.  To enable an effective response to the most pressing challenges facing the land transport sector, transport decision makers (the Transport Agency, the Ministry of Transport and Local Government) will consider the submitted sector challenges when they formulate research topics for the Transport Agency Research Programme.
They are looking for challenges, or ‘broad brush’ indications of problems, which research can assist to address. They are not asking you for research topics for projects. While challenges might not align one-on-one with research projects, elements will be addressed through them.  And so that you are aware, the Transport Agency’s research topic group owners, who are subject matter experts, are likely to be approaching your staff directly to discuss challenges.

If you would like to submit a Transport Sector Challenge please email the Road Engineering Assn NZ Chapter Secretary before COB on Thursday 27th August and your submission will be presented to the NZ Transport Agency.  Please include in your email what you believe to be a challenge to transport sector.
