Day 2 – Optimised Decision Making Presenters

Optimised decision making for the transport sector.  Myles Lind, NZ Transport Agency

New technology will allow the transport sector and our partners to optimise our decision making through the best collection and management of asset data digitally.
This will deliver the safest, most productive transport and utility corridors on our network – now and into the future.
The NZ Transport Agency is now exploring ways to do this, in collaboration with our local government and contractor partners.
We have identified 24 critical work programmes where effort needs to be placed over the next three years to help achieve these goals, in conjunction with the National Land Transport Programme (NLTP).
These programmes are prioritised against the Government Policy Statement (GPS) and address key organisational risks, deliver identified short-term priorities and contribute to deliver the big shifts required for land transport services.
The new approach is expected to extend the 10 percent savings already occurring in the build phase of capital projects across the entire lifecycle of infrastructure assets and the services delivered to customers.
We will develop a programme to implement a digital approach to infrastructure asset management using Building Infrastructure Modelling (BIM). The result will be appropriate for both complex metro networks and simpler rural networks.
This will bring the practice of asset management into the digital age, revolutionising decision making and the ability to work together when collecting, sharing, analysing and using all types of asset management information.
It spans the whole lifecycle of asset management, all aspects of information from as-builts, maintenance manuals and schedules, spatial information, condition, demand, risk, performance and works information.
The Transport Agency will have the capability to provide valuable insights, create efficiencies and deliver cost savings to every decision we make across the asset lifecycle of New Zealand’s 92,000 kilometres of transport corridors.

Using road network performance analysis for effective road asset management.  Ross Waugh, Waugh Infrastructure Management Ltd

Imagine having to manage your personal finances without having access to bank account statements? Likewise, managing infrastructure requires complete and accurate information on the full extent of the network, its performance over time and the costs it requires to maintain and operate. Through initiatives such as the Road Efficiency Group’s – One Network Road Classification (ONRC) and its associated performance framework has greatly enhanced the ability to report and better planning of road maintenance investment. The ONRC performance framework is perhaps the most significant ‘lens’ on the performance of roads that, with other frameworks make a complete set of performance metrics road manager uses. Some other frameworks include the Department of Internal Affairs (DIA), Council specific frameworks and Treasury’s Living Standards Framework. This presentation covers the development of a RIMS Body of Knowledge Guideline for the “Road Network Performance Reporting and Analysis.” The aim of this guideline is to put performance frameworks and its performance measures into perspective for the monitoring of road performance and its use for tactical and strategic level road management.

IDS Project update.  Analytics for the short and medium-term planning of unsealed roads.  Theuns Henning, University of Auckland

Unsealed roads remain the backbone of the New Zealand’s economy. Less than 40% of local roads in New Zealand are sealed, yet most of New Zealand’s farm produce, significant tourism and forestry harvest start its journey to the international market on unsealed roads.  Although much cheaper to maintain compared to sealed roads, the optimal expenditure on gravel roads are difficult to determine, and there is no national program for local councils to adhere.  This presentation covers the development of analytics for the managing of unsealed roads. It optimises the gravel use and grading of unsealed roads in the context of material performance, traffic loading, road classification and topography. It also takes account of user’s perspective of the road performance.

Steps toward multi-asset treatment optimisation.  Fritz Jooste, Lonrix Ltd

This presentation discusses the use of deterioration modelling and optimisation techniques to develop a Forward Works Programme (FWP) across several categories of assets.  Over the past two years, discussions at conferences and industry forums have highlighted the need to consider multiple categories of assets in the development of a FWP.  For example, contractors need to optimise the allocation of resources when designing a comprehensive FWP that addresses the needs of the pavement network as well as off-road assets such as drainage, line-marking and footpaths.  In this presentation, approaches to develop an algorithmic deterioration model that considers and integrates several asset classes at the same time will be discussed.  A literature and industry survey of key needs and constraints with regard to multi-asset FWP development will be presented.  This presentation will also present – in as much detail as possible – the approaches that are currently being deployed in the JunoViewer deterioration model engine.  Key challenges and constraints will be highlighted and discussed and a roadmap for further developments will be presented.  The presentation concludes with specific suggestions for how the findings can potentially be used in deterioration models in New Zealand.

How strong is your bridge?  Optimising New Zealand’s longest road bridge.  Jeremy Waldin, WSP Opus

Many nations around the world have a significant proportion of their road bridges approaching end of life. As an example, over 25% of New Zealand’s existing State Highway bridges were constructed over a 15 year period between 1926 and 1941, many of which are expected to require significant repairs or replacement within the next 10-15 years. In addition to an aging asset, vehicle load requirements are also continuing to increase with a strong demand for heavier vehicles on roads. In New Zealand, the introduction of high productivity motor vehicles (HPMV’s) has significantly increased the demands on existing road infrastructure, causing loads in excess of the capacity of most road bridges constructed prior to the early 1940’s. Therefore, it is becoming essential for asset owners to utilise modern optimisation techniques to extend the life of these structures to avoid having to replace or strengthen a large number of bridges over a short period of time.
This presentation outlines a case study of how modern optimisation techniques have allowed the longest bridge in New Zealand, the Rakaia River Bridge, to support increased loading without the need for costly strengthening or replacement. Optimisation has involved a wide range of conventional and state-of-the-art techniques, including materials testing, verification of boundary conditions, advanced modelling calibrated with field testing, and calculation of a statistically appropriate load factor and bridge specific impact factor. By refining both the capacity of the structure and the load demand, a significant increase in the bridges theoretical capacity was achieved, saving the asset owner over $10M in strengthening costs.

The next step – modelling Footpath Assets in dTIMS.  Paul O’Docherty, Deighton and Andy Bartlett, Central Otago District Council

Since 1998 dTIMS has been used predominately as a modelling and optimised decision-making tool for road pavements in New Zealand.  dTIMS can manage any asset class and is used in many other countries for managing a wide range of infrastructure assets.
Central Otago District Council is currently piloting a model for managing footpath assets. This presentation will discuss the methodology and development of a simple model to predict deterioration of footpath assets and how the same approach can be applied to other asset classes.
Through the collection of new quantitative data – in this case network-wide footpath roughness levels – the model has been developed to bring traditional visual condition rating, asset age and a measure linking both customer and technical requirements together. The survey data can be stored against asset records, alongside the existing construction and condition information held for the footpath network. This is being developed into a measures-based forward works programme to address the critical renewals, demonstrated with a clear evidence base.
This tactic gives CODC the opportunity for optimisation of infrastructure renewals across asset groups, enabling engineers to align footpath renewals with water main replacement programs.

Paul O’Docherty is the business development manager for the Asia Pacific Region at Deighton Associates Ltd. He a specialist asset management consultant with extensive experience in modelling the deterioration of assets, and developing optimised forward works and maintenance programmes. During these 10 years, Paul has worked on models and supported dTIMS for local government, state road and commercial clients across Australia and New Zealand.


Andy has eighteen years of international career development within multi-disciplinary consulting engineering and Local Government infrastructure management. His experience spans across infrastructure, civil, highways, environmental, building services and structural engineering projects. In his current role as Central Otago’s Asset Engineer, he is taking organisational responsibility for technical management of RAMM, Assetic and dTIMS asset management and modelling capabilities.


Empowering senior asset investment planning and decision making.  Steven Finlay, 1.EquiP, Local Government New Zealand

LGNZ EquiP and IDS have completed a study on infrastructure decision making that has highlighted some limitations in the modelling outcomes councils have received. One of the main issues was the disconnect between a robust technical outcome not being connected to councils’ executive and political strategic questions. As a result limited comprehensive information is available to enable governance and senior decision makers to reach the best possible decisions for their infrastructure investment. IDS and LGNZ EquiP have partnered to assist councils in bridging the gap between asset management and governance. By provide another layer of services and support for Local Government Senior Management and Councillors, together we will create compelling business cases which will provide investor confidence.

Steven joined LGNZ as Manager Business Solutions in April 2014 to drive the operational delivery of EquiP, LGNZ’s Centre of Excellence. Steven’s PhD developed a new theory of indigenisation, using a comparison of a Scottish Celtic (his own background) and a Maori organisation to understand how indigenous knowledge enables organising practices.  The PhD won a scholarship from Victoria Management School.   Together with wife Susan, Steven leads a busy life on the Kapiti Coast. With their three girls, they love exploring the underwater treasures of Kapiti Island and the tracks of the Tararuas. Steven is also active in the Kapiti Boating Club and Paraparaumu College Parents’ Association.


Transforming foothpath data to dollars – Lessons learned.  Gregg Morrow, WSP Opus

There is a growing need for local governments to provide condition and performance information on their footpath network, since the release of the Government Policy Statement on Land Transport in 2018, because the New Zealand Transport Agency (NZTA) will now assist in funding footpath renewals.  This presentation will describe the lessons learned by WSP Opus during their first year of collecting and analysing data from surveyed pathways.  These lessons will be helpful to other local governments for transforming data to information for evidence-based, transparent asset management planning and business cases.
Smart data collection ensures the data collected can be combined with other sources to produce required information about now, and the future.  Examples of useful information from work completed to date includes:

  • Identification of safety hazards requiring immediate action (Trips);
  • Dashboards benchmarking investments and performance for defined Areas;
  • An advanced algorithm for defining treatment segments that balance renewals to address poor condition with aesthetic impacts;
  • A suggested forward works programme made up of candidate sites, used to align footpath renewals with other road and utility works to create projects, whole of corridor approach.

The following lessons were learned for work completed to date:

  • Road inventory data such as centreline and carriageway direction need to be accurate as well as footpath data to generate useful information;
  • Updating both footpath inventory and condition data at the same time can be more complicated than expected
  • There is a balance between correcting data to improve information, and correcting data solely for mapping purposes.
  • Separating the footpath FWP from the road FWP will require new processes and additional coordination.

Upon completion of the survey the client now has a significantly improved dataset, used secure funding and ensure it is spent in the right place, on the right thing, and at the right time, to achieve the required outcome.


Gregg is a qualified civil engineer with over 26 years’ experience in the delivery of asset management (AM) related services, both as a Local Authority Engineer, and a consultant.  He is currently the Group Manager of the Asset Management Team in WSP Opus’ Auckland South office.  Identification of the required datasets to support informed decision making has been core to Gregg throughout his career. This includes base inventory (locational and characteristic information) as well as condition data required at the three AM hierarchy levels. Gregg is recognised within the industry as a thought leader in identifying data requirements and data capture and storage processes to support informed decision making and better Asset Management practices. This approach led to him being assigned the Technical Manager’s role in the Austroads Data Standard for Road Investment and Asset Management.
