LEADERSHIP

MINISTERIAL ADDRESS 

The roading network is at the core of the new government’s priorities around improving our infrastructure. We need to move ahead as a country that is connected both in urban centres and in the regions with a fit-for-purpose and high-functioning transport network. To this end the Government has announced thirteen new RONS projects and allocated additional funding to road maintenance and improvements. 

• funding and financing. Modernising the Crown’s finance governance to allow for more private funding 
• congestion needs to be reduced in high-growth areas which will help to reduce emissions
• local government funding 
• reducing waste around time and resources spent on broader outcomes 
• RONS update 

Hon Simeon Brown – Minister of Transport, Minister of Local Government, Minister for Auckland

LEADERS’ PANEL: LOOKING TO NEXT YEAR’S WORK PROGRAMME 

What is the next step for industry under the new government? 

With a new government in place and a strong focus on roading infrastructure, how will the next three years look for the roading industry? Priorities and investment have shifted but what does this mean for councils and contractors? And is ‘doing more with less’ still happening, or is it more about finding efficiencies and doing what can be done?

• unpacking the NLTP 
• paring back broader outcomes, or finding better efficiencies? 
• alternative financing and investment models 
• lowering compliance costs 
• current state of the consenting and fast-track consenting processes

PANEL DISCUSSION: SOURCING RECYCLED AGGREGATES FOR YOUR PAVEMENT

Recycled aggregates provide a number of advantages over virgin materials when delivering a quality pavement. It has been demonstrated that recycled aggregates have reduced emissions and can provide superior performance. As councils have gained experience with recycled aggregates in pavement construction, it has increasingly become a focus area on reducing Scope 3 emissions.

Councils and the wider industry are working more collaboratively to deliver infrastructure that is more sustainable. One of the big challenges is where to source these materials, ensuring only quality products are supplied and having the whole supply chain engaged in delivering outcomes. In this panel we take a closer look at:

• the role of recycled aggregates in your roading materials strategy. The role of emission reduction targets
• de-risking the final outcome. What specifications and processes are required to ensure success?
• availability, where to source and how this can impact the cost equation
• road types suited to recycled aggregates and what the specs say – high volume, low volume, State Highways
• sustainability outcomes and how to communicate these to your stakeholders
• the availability of recycling centres for raw inputs and how the waste minimisation levy is changing behaviour

PROCUREMENT UPDATE: NZ TRANSPORT AGENCY WAKA KOTAHI 

The national transport agency is overhauling procurement across its roading spend under the new Infrastructure Procurement Strategy and Integrated Delivery Model.  

This will see the incumbent NOC model for state highway maintenance procurement replaced and a more system-wide and regionalised approach. There will be impacts and opportunities for local government, contractors and consultants. 

Alison Murray – head of procurement, NZ Transport Agency Waka Kotahi

PROJECT OVERVIEW: TE UTANGANUI AND THE MANAWATU REGIONAL FREIGHT RING ROAD

Te Utanganui - the Central New Zealand Distribution Hub - is a unique intermodal distribution hub in Manawatū. It is well served by international ports and is the only place in New Zealand where road, rail and air transport options are immediately adjacent to each other. Several infrastructure projects either planned or underway, combine to establish Te Utanganui as the primary distribution and transport hub for central New Zealand.  One such project is the Manawatū Regional Freight Ring Road. Palmerston North City Council is leading the investigation and planning for this significant transport infrastructure investment that will move heavy transport away from the city centre and better link the freight network of Te Utanganui to the existing State Highway network.

• how the project links to and supports the wider freight network
• economic benefits of investing in freight and logistics infrastructure
• multi-agency collaboration to deliver an integrated programme of projects
• key challenges to delivering the ring road
• financing considerations including new financing models

David Murphy - general manager strategic planning, Palmerston North City Council
Robbie Woods - programme director, Te Utanganui

CHANGES TO STATE HIGHWAY MAINTENANCE 

The new Integrated Delivery Model for state highway maintenance is set to be rolled out in early 2025. Significant changes are afoot, with a focus on efficiencies and a closer working relationship with local communities. 

• how the IDM works and what this means for your organisation – contractor, consultancy, local government, supplier 
• moving towards a new approach to Temporary Traffic Management 
• 24-hour pothole repair 
• efficiencies gained through road closures for major maintenance and repairs (case study – Central Waikato)

Andrew Clark – national manager maintenance & operations, NZ Transport Agency Waka Kotahi

Andrew will also be hosting a Round Table discussion on Day Two for extended Q&A and discussion on this subject. See the Day Two programme for more information.

THE APPLICATION OF TIME-OF-USE CHARGING IN AUCKLAND CITY

• Auckland Council and AT are jointly developing the detailed policy and design of a Time Of Use Charging (TOUC) Scheme for Auckland.
• This work will inform Council’s submission to Government’s Select Committee when it reviews the draft enabling legislation, expected in early 2025.
• The Scheme intends to reduce congestion by charging motorists for driving on the most congested parts of Auckland’s inner road network with costs varying by the time of travel.
• Addressing equity concerns through design choices, mitigations and revenue allocation is a key element of the design process.

Michael Roth - Auckland Council

REDUCING MATERIALS COSTS: ALTERNATIVES TO THE M/4 SPEC 

It is a common misconception that you need to use the M/4 gravel specification in all instances. In fact this can lead to increased costs carting expensive virgin aggregates all over the country. So what are the other options? 

• overseas developments relevant to New Zealand 
• alternatives to M/4  
• incorporating local materials into your specs 
• sustainability considerations 
• New Zealand case studies of alternatives and how they’ve performed to date 

Bryan Pidwerbesky – technical director - pavements and materials, Fulton Hogan

UPDATE ON GOVERNMENT PROCUREMENT  

Where is government procurement heading and how will the new government procurement rules impact the roading sector and what does the new framework look like?  

• what were our key drivers for change? 
• new procurement behaviours being encouraged 
• how will agile, faster procurement be supported by the new framework? 

Laurence Pidcock – general manager NZ Government Procurement, MBIE 

AUCKLAND TRANSPORT: FUTURE INVESTMENT PROGRAMME AND PARTNERING WITH INDUSTRY

The country’s largest city has ambitious plans for its transport network with projected spending of $16 billion over the next 10 years.

With population growth, traffic is forecast to increase on key arterial roads from around 28,000 vehicles per day to in excess of 35,000. 

The 10-year transport investment programme includes significant investment in road asset renewals, together with a range of road network enhancements such as intelligent intersections, dynamic lanes, special vehicle lanes, and network demand pricing. 

Auckland Transport is seeking to partner with industry to deliver roading renewals and new capital projects ‘better, faster, cheaper’.  To this end it is seeking innovative ideas around material-use and road-construction methods to reduce embodied carbon and the cost of temporary traffic management.

ACHIEVING SKID RESISTANCE WITHOUT COMPROMISING THE QUALITY OF YOUR PAVEMENT 

There are a range of factors to consider in incorporating skid resistance into your road surface specification – cost, material availability, pothole risk, durability and lifecycle. 

• using hot chip to achieve texture without reducing waterproofing through watercutting
• using a flushing model to help determine pavement end-of-life
• reducing short term SCRIM sealing by promoting the use of aggregate performance data
• cost considerations around using broken faces to provide skid resistance
• and what the alternatives are

HARNESSING ADVANCED TRANSPORT DATA SOURCES: INSIGHTS FROM HAMILTON
 

Hamilton City Council will share its experiences with some of the latest transport data sources. The presentation will cover telemetry data from providers such as Near, ERoad, TomTom, and CompassIoT, alongside video analytics for safety assessments from AMAG and Vivacity, drone surveys by Urban Connection, and mid-block multi-mode surveys by Opito.

Additionally, you’ll hear about its recent trial of over 15 different traffic counting technologies to see if there is a viable alternative to traditional pneumatic tube surveys.

This session will provide practical insights into these data sources and how they are being used to improve transport operations and planning in Hamilton.

John Kinghorn – transport systems engineer, Hamilton City Council   

INTERNATIONAL SPEAKER: DEVELOPMENT OF A NEW LIME-BASED BINDER BLEND FOR SOIL STABILISATION APPLICATIONS

There exists an interest globally to identify eco-friendly alternatives to traditional binders such as cement and lime for soil stabilisation. This case-study presents the development of engineered low carbon cementitious binders that can permanently modify and strengthen a broad spectrum of soil types. The newly developed binder utilises the well-established principles of modifying clayey soils using lime and integrates a synergistic blend of naturally sourced pozzolanic materials with lime and limestone fines to optimise both mechanical and environmental performance.

• lowering plasticity of soils
• comparisons to cement for 7- and 28-day unconfined compressive strength (UCS)
• comparisons to quicklime
• lowering the volume of binder used
• feasibility and optimal composition of the binder for treatment of other soil types

Narain Hariharan – new products and applications manager, Graymont

THE NEW ZEALAND BITUMEN SUPPLY CHAIN AND CONSIDERATIONS AROUND COST, QUALITY AND AVAILABILITY

The bitumen landscape has changed significantly since the closure of Marsden Point and exit from the market of Z Energy. In this presentation we hear about the bitumen supply chain as it stands today, where it is headed and considerations for the roading industry.

• current importing, storage, blending/treatment and distribution
• room for another bitumen importer
• NZTA’s role and whether its import specifications are too rigid
• current pricing, where is it heading and international benchmarks
