There are lies, damned lies and Key Performance Data.  Charles Agate, Wellington City Council

The National Code of Practice for Utility Operator’s Access to Transport Corridors seeks to achieve several worthy aims. One of these is to deliver reports that indicate the performance of the code and how it is or is not delivering the desired outcomes. There are four Key Performance Data indicators. The number of Corridor Access Requests submitted each year, the number of completed Works Completion Notices each year, the number of Non-conformance notices issued each year and last but not least the number of Third Party Damages Incidents each year. Count four things, compare the figures with preceding years spot the trends, job done, too simple! No it isn’t and here is the story about how we wrestled with this seemingly innocuous monster.

Charles is the current Traffic Management Coordinator (TMC) / Corridor Manager for Wellington City Council. With a small team of 5 they are responsible for the coordination, approval and compliance of all third party works within their Network. From Major Water Renewal Projects, 18 Story Apartment Block Developments to Accessing Utility Chambers and Installing Driveways, they know about.
With more than 10 years Local Government experience Charles is passionate about the local roading network and how it is used.

The use of UAV’s to assist Road Corridor Management.  Dave Stewart, WSP Opus

The use of UAV to capture imagery and video of the road corridor from unique viewpoints opens up a number of applications for network managers.  As part of inspection activities on the Wellington Network,  Opus, on behalf of Capital Journeys and NZ Transport Agency, has been using utilising UAV’s to enhance data collection and risk assessment.
The use of UAV’s has primarily been used as part of geotechnical investigations associated with management of the network.  This paper discusses examples of the use of UAV on the Wellington network and elsewhere for : (i) incident response and (ii) assessment of difficult-to-access sites geological threat sites.
The use of UAV can provide significant safety and efficiency benefits by removing the need to : (a) expose site staff to high risk site conditions or (b) implement costly / disruptive traffic management measures.
The paper will provide examples of where this has been implemented as well as outlining the benefits and limitations of UAV inspections.
NZTA has implemented rules for approving UAV flights over NZTA land.  These include the requirement for pilots to be certified under CAA Part 102 (August 2015) and UAV flight access restrictions based on the traffic flow (AADT) of the road.  The examples provided will cover safe working practices developed for flights at difficult and high flow sites, which involved consultations with NZTA.
In addition to photos and video obtained from UAV’s, post processing of imagery with dedicated software can produce 3D models which in many cases surpass those from conventional surveying. UAV generated survey data can be utilised for a wide range of applications ranging from terrain analysis for risk and resilience assessments, site visualisations for presentations to stakeholders, development of remedial or upgrade options and survey cross sections and plans for designs.  Examples will be presented of these applications.  Future applications include use of sensors to detect condition of pavements and structures.

Collaboration with Utilities – How do Local authorities survive?  Tracy Bell, Timaru District Council

Clever collaboration can have last impacts on all providers, and provide benefit to the shared customer, the Public.
Territorial Local Authorities (TLA’s) and the New Zealand Transport Agency (NZTA) are responsible for managing and maintaining the road corridor network up and down the country.  As part of this management process NZTA and TLA’s are required to allow access of Utility Operators to the road network, in order for these Utility Operators to build, maintain and renew their own networks, such as three waters, power, telecommunications and gas.  NZTA and TLA’s also have a need to build maintain and renew the road asset.
Embedded in current legislation “The Code of Practice for Utilities Access to the Road Corridor”, it is required that the Local Authority (Corridor Manager) allow access but at the same time ensure the Public are not inconvenienced.
Many local authorities, utility operators and contractors try to work together to make sure that when works are carried out in the road corridor, it is done efficiently and expediently.  Ensuring project alignment is crucial for not only project management purposes but to ensure Council’s limited renewals budgets are not needlessly squandered.  This causes frustration to all parties, particularly those on site, explaining to shared customers why they are digging up new footpaths or roads to put in underground assets!
It all comes down to relationships between the various utility’s providers, and everyone needs to work together for the benefit of their shared customers. The best advice that I can give from my own experience is to become friends with your Corridor Manager. If you are the Corridor Manager become friends with the Utility Managers.

Tracy has been the Road Corridor Technician for Timaru District Council for the last 8 years.  She is responsible for the Corridor Management of the Timaru District and more recently the Mackenzie District, this requires her to ensure the efficiency  of the Corridor Access Management system, which incorporates the Traffic Management Approval and Auditing process.
Due to the size of the Timaru and Mackenzie Districts, this role allows Tracy the ability to interact directly with contractors on a daily basis.
Prior to starting with Local Government Tracy spent 9 years gaining related experience in the contracting industry.


An alternative to steel plates.  Oliver McLean, Vanguard

As part of a family-owned business, we exist to provide the New Zealand market with fit-for-purpose products that help to minimise and prevent safety incidents on work sites, whether that be in warehouses, carparks, construction sites or civil sites.
Steel plates have long been the go-to solution anytime an excavation/hole in the road or footpath needs to be temporarily covered to allow vehicle and pedestrian access. However, steel plates pose numerous challenges, such as wasting valuable operational time getting steel plates delivered to site and manoeuvred into place; the danger of swinging heavy steel plates around on site; steel plates being used without anti-slip coatings posing slip risks for vehicles and pedestrians; or even the harsh noise of steel when vehicles drive over them.
We will be presenting a comparison between the use of steel plates compared to fibreglass road plates, as an educational insight into how temporary hole/excavation covers can be handled in a safe, efficient and professional manner. In addition, we will have product samples at our stand for viewing and discussion.

I’m part of a family-owned and operated business and in my 4th year with the business.

My role is visiting and working with civil contractors/utilities companies around the country, doing our small but important contribution of helping them to improve safety and efficiency on their work sites through the use of innovative products.


The changing face of urban mobility.  Claire Pascoe, NZ Transport Agency 

New Zealand towns and cities are aspiring to be better places to live, work and play and the transport system plays a significant role in their journey. Changing urban mobility systems however is as much an ‘adaptive challenge’ as it is a technical problem which means we need to think more broadly about how we tackle the challenge. With national and local objectives to increase the number of people travelling on foot, by bike or on public transport, we’ll need a comprehensive approach to change that includes reviewing many of our business as usual processes.


Claire Pascoe is the Lead Advisor Urban Mobility at the New Zealand Transport Agency. In her current role, she provides technical expertise and leadership in relation to rebalancing the transport system, providing people with genuine options for getting around our towns and cities and making them healthier places to be.  She was previously involved in developing and delivering the Urban Cycleways Programme and managing the national cycling culture change team.


Temuka Trunk Water Main – Urgent unplanned replacement. Ashley Harper, Timaru District Council

At 4.45 pm on the 5th of December 2017 advice was received that the Temuka Water Supply contained ‘enormous amounts of asbestos fibres’. This advice was received following the analysis of water samples that were causing washing machines and shower heads to block with ‘fluffy like’ material.|
Medical advice was urgently obtained which confirmed that when ingested asbestos fibres were not a health hazard but when inhaled they could cause health issues such as lung cancer.
A comprehensive media plan was put in place while a strategy was urgently developed to overcome the immediate problem and determine a long term solution.
A filtration plant was assembled and commissioned by the 20th of December 2017 and on the 12th of January 2018 an extraordinary meeting of the Timaru District Council approved the replacement of 9 km of 300 mm Asbestos Cement trunk water main with a budget of $3.5 million.
By the 26th of March 2018 the 450mmm HDPE replacement pipeline had been installed and made operational.
The pipeline components and the physical work were generally procured via competitive processes and at the peak of construction 15 excavators were involved across six work fronts.
The presentation describes the timelines, communication techniques, procurement methods, construction details and the outcome of this urgent work.

Ashley Harper is the Infrastructure Group Manager for the Timaru District Council and has held this role under various titles since 1989. He is a Chartered Professional Engineer, Life Member of IPWEANZ and was Chairman of this organisation from 2007 to 2009.

It’s not always a pretty picture: Roadworks and what they mean to Utilities.  Tanya Bowers, Chorus 

For many NZers access to broadband and phones is a fundamental part of life! Not having access can be both frustrating and at times life threatening. The same applies to power, water and gas.
Damage to telecommunication infrastructure impacts on New Zealand, imagine no:

  • Eftpos
  • access to 111
  • communicating with loved ones here and overseas

We chose this topic as we need your help to ensure decisions made around what happens to infrastructure in the road corridor includes engagement with the owners of those utilities.
Decisions made have a direct impact on New Zealand and New Zealanders. Working together is the key!


Tanya has been a Stakeholder Operations Manager with Chorus for 5 years with a total of 27 years in the telco industry. Working as part of a small team within Chorus she looks after the operational management in the field ensuring Code compliance and issues are managed.

Traffic control devices (road signs, marking and signals).  Mark Edwards, NZ Transport Agency

Legislation, best practice and guidance in relation to the use of traffic control devices (road markings, road signs and traffic signals) are constantly evolving. Most recently Part 5 of the Traffic Control Devices Manual (Traffic control devices for general use – between intersections) has been the subject of public consultation as this section of the manual is updated.
The purpose of traffic control devices is increasingly under challenge by modern society’s expectations and technology. Whilst all traffic control devices need to reflect modern needs and expectations they also must retain their core function in order to contribute to the safe and efficient operation of our road network.
In order to achieve this traffic control devices need to be uniform in form, appearance and placement.
Road Controlling Authorities play a key role in promoting road safety through the use traffic control devices and in applying engineering judgement in the context of what they must do, what they should do and what they may do.
Road Controlling Authorities are also vital in trialling new traffic control devices. Trials take place regularly and the learnings from trials are shared with the sector in order to help determine whether the trial has proved successful.
This paper will delve a little into what is expected of Road Controlling Authorities, how the sector works collaboratively and what the difference is between must, should and may.
It will describe how the traffic control manual is updated, some of the aspects in the recent Part 5 consultation, what is in the pipeline and how new traffic control devices are trialed.


Mark joined Transit in the early 2000s as the Wellington Region’s safety engineer prior to taking up a role at the National Office. He has recently re-joined the NZTA having been at Greater Wellington Regional Council for nearly five years.
Mark’s current role is primarily a regulatory function in relation to the Traffic Control Devices Rule and the related specifications, standards and guidance for traffic control devices. This includes working with RCAs in trialling new signs, markings and traffic signals.

Applications of satellite imagery for Road Risk Analyses.  Selwyn McCracken, Stantec

Satellite imagery data is emerging as an alternative data source for some road management and risk assessment applications, given the recent improvements in price, spatial resolution and frequency of data collection.

This talk will outline:

  • A case study where satellite imagery was used to identify sites at risk of vegetation encroachment across a 4,415km electricity distribution network.
  • An overview of other applications of satellite data that could be used for road related activities such as: land/slip movement monitoring; measuring flood extents and road side drainage issues; capturing 3D terrain/surface models and monitoring erosion; identifying logging activity that could lead to increased road damage; and assessing fire risk from dry vegetation.

For vegetation risk assessment and monitoring purposes, satellite imagery analysis was found to be a cost-effective and reasonably accurate method of high-risk site identification, relative to other significantly more expensive data collection techniques, such as ground based assessments or Aerial LiDAR / photogrammetric surveys. As such, it is highly likely that other routine road-related risk assessments will also begin to make greater use of satellite data, especially when large assessment areas are required.


Selwyn is a Principal Data Scientist at Stantec where he specialises in delivering strategic advice based on predictive analytics, scenario modelling and the extraction of actionable insights from large and challenging datasets.

Much of his work at Stantec focuses on identifying cost savings for asset management and infrastructure planning.

He has a PhD in the obscure field of Occupational Epidemiology which, unexpectedly, turned out to be extremely useful in modelling the survival of roading infrastructure.
