Road Network performance monitoring and management guideline. Theuns Henning, IDS & University of Auckland

The RIMS Group Recent released a new guideline on the monitoring and management of road infrastructure.  Sponsored by Queenstown Lakes DC, it forms part of the Body of Knowledge and aims to assist authorities in better decision making for investment in maintenance programmes through performance monitoring, reporting and management. The objectives of the Guideline are:

  • Improve the understanding of how the network performs through specific measures (what they measure, how it can be used) and its performance from a statistical point of view
  • Clarify the performance management implications as viewed from different performance monitoring frameworks used in New Zealand, including One Network Road Classification (ONRC), Department of Internal Affairs (DIA) and Council specific frameworks
  • Improve the understanding of linking performance outcomes to the appropriate maintenance programme and investment profile
  • Define the data implications on performance monitoring and need guidance to the type, frequency, quality and processing of condition data

Based in Auckland, New Zealand, Dr Theuns Henning holds many roles within the civil engineering industry, drawing on his academic background and industry experience. Theuns is a published author of 39 international journals, six Road Infrastructure Management (RIMS) Body of Knowledge Guidelines and is the primary author of four World Bank Guidelines for developing countries. He holds a Masters of Engineering (Transportation) from the University of Pretoria, South Africa and completed his PhD at the University of Auckland in 2009, where he was the recipient of the Foundation for Research and Technology Bright Future Scholarship.

Putting TSD on the map – spatially representing traffic speed deflectometer data. Grant Clarke, Downer


TSD data is now available for the majority of the State Highway network.  For many of us, there is a question of can we use this data?  And if so, how do we use it?  This presentation outlines a spatial approach on making the data available in a usable format for our asset management analysis and decision making processes.
Moving from technical data to mapping output can be a daunting task for an Asset Information team.  This is made easier with multidisciplinary input from Downer specialists and Asset Management practitioners.  Understanding the start and end points allowed the Asset Information team to move forward with confidence.
Transforming the TSD data into SNP values is computationally intensive with a number of data quality issues that need to be addressed.  Achieving processing efficiency is critical when calculating values for a whole network.  Trapping errors in various input and calculated values is essential to ensure output integrity.  Good mapping demands that the SNP values be summarised in appropriate granularity along with spatial referencing.  The final data step before mapping is to translate the SNP into strength categories.
Mapping output is added to Google Maps which is shared with our Asset Managers.  This can be used by itself or combined with layers from other datasets.  For example, combining the TSD with the Forward Work Programme gives a cross check on treatment selection.  The mapping output has been used to assess network health against HCV growth and the quick assessment of network pavement condition on new networks.

Grant Clarke is a Senior Asset Information Manager with Downer NZ, based in Christchurch since 2013.  He is actively engaged in NZTA Network Outcomes Contracts as well as providing asset information management support to local authority road maintenance contracts.  One focus area for Grant is supporting the Downer asset management practitioners with network wide data analysis including mapping the resultant information.

Red bridge investigation. Anu Ileperuma, Hastings DC and Natalia Uran, WSP

Red Bridge is located on Waimarama Road, Hastings, spanning across the Tukituki River, on a strategically significant, proposed High Productivity Motor Vehicle (HPMV) route in the district. Following inspection findings, where cracks were observed in parts of the bridge, and after an update of the VDAM General Mass regulations to 45/46 tonnes in December 2017, the bridge was restricted to 90% Class 1 with a 10km/hr speed restriction.  Along with Red Bridge, a further 25 bridges were also restricted within the district.
This presentation outlines a case study of how modern optimisation techniques have allowed Red 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, advanced modelling calibrated with field testing, and real time monitoring.  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 $2.6M in strengthening costs.

Anu is a Hastings District Council Bridge Engineer with a Bachelor in Civil Engineering (Hons).  Her portfolio covers the capital works and maintenance of bridge assets within the Hastings district and she has been with the Council for over five years.

Natalia is a Senior Bridge Asset Engineer with a Bachelor (Hons) in Civil Engineering and a Masters in Structural Engineering (Distinction).  Natalia has over 12 years’ work experience in the UK and New Zealand.  Natalia’s work experience has primarily been concentrated in bridge inspection, strengthening designs, live load bridge assessments and asset management for a wide range of clients including NZ Transport Agency and Local Authorities.  Natalia currently leads the Bridge and Civil Structures team for the WSP Napier office.

The new Candidate Selection Algorithm Project: What, Who, Why, When. Mike Tapper, Beca

This project currently being undertaken seeks to achieve two objectives.  The first is to implement improvements to the treatment selection algorithm, that sits within RAMM, based on the findings of the Waka Kotahi Research Project published in 2016.  The second objective is to make available the coding for the updated renamed Candidate Selection Algorithm.  This presentation discusses the project, improvements from the previous Treatment Selection Algorithm you all know and love and what the outputs will be.

Mike is a technical with Beca with over 25 years experience in road asset management.  Mike has led asset management, condition survey, traffic counting, network management professional support services contracts across both national and local authority clients and networks.  Mike co-led three research projects for Waka Kotahi, including improvements to the visual condition rating and treatment selection algorithms.  Mike is currently coordinating the new Candidate Selection Algorithm (CSA)  project, a project to make available an improved updated CSA from the old Treatment Selection Algorithm buried deep (so deep!) within RAMM.

The road to a sustainable Aotearoa. Dr Kate Meyer, Beca

Movement of people and freight will continue to be essential to maintaining our society, but we must reduce the environmental impacts and plan for resilient systems. Energy use associated with transport systems contributes roughly 20% of NZ’s greenhouse gas (GHG) emissions and is a significant source of air and water pollution. Of this, 90% is land transport. Further, over 2000km of NZ roads are exposed to sea level rise risk, with a replacement value of approximately $1b. Dr Kate Meyer will talk about opportunities and challenges as we seek to future-proof our road infrastructure, decarbonise our transport systems, and maintain societal connectivity over the coming decades.

Kate is a sustainability scientist, an engineer, and an author. During her early career, Kate led the sustainable design for many award-winning buildings and precincts in NZ, Australia, and Singapore. In her role as Business Director for Sustainability, Kate leads Beca’s efforts to positively impact community, economic, and environmental outcomes across all the geographies we touch. Kate also specializes in connecting sustainability science with business, government and behaviour applications and is a Trustee and the Founding Director of the Planetary Accounting Network, a charitable trust dedicated to helping people, businesses, and governments operate within the planet’s limits.

Setting the Scene. Tracy Bell, Timaru DC & Ria Apiata, KiwiRail

As sponsors of the “Utilities Access to Transport Corridors” stream on Day 2, NZUAG will set the scene for the day, outline how the Code is performing across the country, explain the changes that have been made to the Code as the result of the latest review and update participants on the NZUAG work programme designed to improve the effectiveness of the Code for industry and the public.

Feeling roadblocked when it comes to entering KiwiRail’s corridor? Bryce Ongley, KiwiRail

Having been a civil contractor in the water industry for over 20 years, Bryce has felt the same pain as you accessing KiwiRail’s corridor. This is the very reason he threw down his tools to make the move over to be the National Corridor Manager for KiwiRail. He has been on a mission to improve the customer experience in accessing the corridor, without compromising safety of course.  In fact, Bryce’s session will give you an update of the progress that has been made towards a better experience and the recent lift of safety and compliance. Albeit, there is further work to do, that’s a given, however this session will touch on ways to continue the move in the same direction. We need everyone to keep lifting their safety game and this can be done by submitting high quality safety plans and methodologies, to give KiwiRail the confidence in you. Come along and meet Bryce, he’s there to engage and hear how your experience is going. Ensure that you are included on the list of invites for KiwiRail’s contractor engagement meetings.

Bryce is Kiwirail’s National Corridor Access Manager tasked with managing the safety of all Contractors in the Rail Corridor from Otiria to Bluff. Having been a Contractor himself, one of the biggest challenges of his role is turning around the Permit process and building successful contractor relationships throughout the network while spreading the word about Rail Safety.
He’s got over 20 year’s experience being a contractor and managing Contractors and knows first-hand about the challenges of safety in complex environments.


Better, Longer, Faster! Andrew Healy, beforeUdig


Corridor Manager’s seek better practices on their roads, longer periods of free flowing traffic and faster excavations. That only happens when workers are competent and skilled and is why our organisation has launched a highly successful Australian Locator Certification programme in New Zealand. More than ever Locator’s are being used by contractors to identify assets in the road corridor. Ensuring contractor confidence in a Locator’s skill set is vital to reducing damages, decreasing disruption to the road corridor and more importantly eliminating serious injuries to workers or the community. Hear about why we have invested significant time and collateral to bring this competency standard to New Zealand, the benefits it brings to our industry, and how you can work with us, other industry bodies and utilities to bring about the better, longer, faster environment we all seek.

Andrew has an extensive background working with Local Government and Utilities delivering solutions across multiple departments. He is key to ensuring NZ utilities, central and local government capture the asset protection and H&S benefits of beforeUdig. Across NZ Andrew strives to bring a ‘next level’ of value and benefit to the industry, delivering innovative software solutions and programmes and promoting best practice for protection of infrastructure and life.

Is ‘Not in my front yard’ the new NIMBY? Experiences and learnings from electricity asset installation and replacement in transport corridors. Adam Du Fall, Powerco


How do we manage assets that everyone needs, but few want? Juggling an (at times) congested transport corridor with the needs and wants of a community can be difficult. The Utility Operator’s Access to Transport Corridors Code of Practice sets out the framework for accessing, installing and maintaining infrastructure in transport corridors, but how do we manage the growing interest and opinion’s from customers? Is the Code the right mechanism to use?
