The impacts of climate change on our stormwater and wastewater systems
Author & Presenter: James Hughes, Tonkin + Taylor

What will climate change mean for our stormwater and wastewater systems? This study presents findings from Deep South Science Challenge funded research into this important issue.

Much of New Zealand’s stormwater and wastewater infrastructure is vulnerable to the risks associated with a changing climate, including sea-level rise or increasing extremes of rainfall and/or drought. The nature of existing stormwater and wastewater systems mean that they will be significantly impacted in a wide variety of ways including the increasing occurrence of compounding hazards. For example, many discharge to low lying areas, and it is these coastal and riverine locations that are most at risk to flooding associated with increasing rainfall intensity compounded with rising sea levels and changing groundwater levels.

This paper presents findings from Deep South Science Challenge – funded research on the economic, environmental, cultural and social impacts and implications of climate change on New Zealand’s stormwater and wastewater systems. In addition to identifying impacts and implications, the study identifies regional priority areas, and develops a series of guiding principles for managers.


Intuitive decision making for infrastructure strategists

Author & Presenter: James Thorne, WSP Opus
Co-author: Dr Eric Scheepbouwer, University of Canterbury

Who can we trust to make the strategic infrastructure decisions that our country desperately needs? Wisdom tells us to first look to the industry experts. But how well are we cultivating this intuitive expert knowledge? Does the decision making process hold up to scrutiny and is it conducted in a framework of continuous improvement?

This paper follows on from my 2016 IPWEA presentation and showcases the results of my master’s thesis research examining “Intuitive Decision Making for Wastewater Pipe Networks”.

I’ve pilot tested a method for documenting wastewater network renewal decision making with the aim of supporting continuous improvement in this strategic infrastructure focal point. The research method includes a survey capturing the intuitive insights of over 40 industry experts to document the collective importance of the various factors considered during the wastewater network renewal planning process. The ideas presented within apply beyond wastewater networks and hold relevance wherever decision makers are faced with the challenge of complex socio technical infrastructure systems. In other words, just about everywhere…

 

Quality assurance in pavement construction – our legacy
Author & Presenter: William Gray, WSP Opus

The principles supporting pavement construction Quality Assurance in New Zealand are known.

How often however, when as-built pavement performance does not meet our expectations, do we find that Quality Assurance has not been effective and largely administrative?

With input from the industry, the authors developed the Quality Right initiative in pavements for the New Zealand Transport Agency. Quality Right aims to positively influence all stages of pavement delivery including: procurement; pavement design; material supply; pavement construction, including subgrade and pavement layer preparation and surfacing.

In this paper the authors discuss how Quality Right in pavement construction means the Principal, Contractor and Engineer share and use current, explicit information about the works to support informed, collaborative decision making, delivering sustainable, resilient pavements.

The Road Asset Management Plan – Make it, test it and sell it. Mike Holeszko

Asset management by definition is the practice of managing the entire lifecycle of an asset. For a road, the purist engineer designs a pavement for an expected 20 year life taking into account many factors such as; subgrade resilience, expected commercial traffic loading, and environmental effects such as underground water or rainfall. Classic failure is defined as a 20mm rut due to repetitive loading over the design life.

In truth many existing pavements have well and truly exceeded their design life but are still in service. They have suffered the ravages of time including failure of the seal coat (oxidisation, poor design, stripping, gone fatty etc.), prolonged periods between reseals, too narrow for modern traffic volume and size, poorly maintained drainage systems, poor shoulder maintenance, and a lack of funding to keep them in serviceable condition. Typically they may exhibit conditions such as; cracking, rutting, roughness, poor seal texture, or resemble a patch work quilt through extensive patching.

Through technology we have arrived at a point in time where road managers can move from empirical funding allocations based on intuitive and experience based knowledge in one’s head to high speed detailed pavement condition capture via a survey vehicle and sophisticated analytical financial software. Additionally maintenance defect software allows collection, logging and pricing of defects to create defect backlog lists.

The perennial problem still exists of convincing those potentially non-technical, financial controlling folk as to an appropriate level of funding to adequately service the needs of the desired asset lifecycle.

This paper recognises the role of salesmanship, of pitching and selling a product or concept to a selected audience. The selected audience needs to feel a connection to the concepts presented, feel there is truth in the data and feel compelled to, in this case, fund (or buy) the proposal (or product).

The author presented a paper in 2004 about Road Condition Indices following the achievement of a successful pitch convincing the regional management team of where funds should be allocated. These indices were presented in a graphic format with various columns stacked upon each other (affectionately known as Chimney Stacks).

  • The road network was split into groupings by road function/category and compared road features within that subset (apples with apples).
  • Deficiencies only appeared graphically if they were below an indicative state of acceptable condition.
  • Road importance was graphically represented by Equivalent Standard Axles (ESAs).
  • The maximum value used to calculate an index was in some cases a statistical maximum just to eliminate very high isolated results. This provided better graphic representation of the population.

In the 13 years from 2004 the author has become acutely aware that selling the idea or any idea requires a pitch that may differ depending on your customer. For example engineers can be heavily swayed by a detailed engineering data and calculations rather than a fluffy concept. Politicians from a non-technical background could be driven by a different pitch. This paper elaborates on the RCI concept and how to orientate your pitch to gain maximum purchase of your argument.

Mike commenced with Queensland Department of Main Roads in 1985 and worked with them for 28 years in all facets of engineering within District operations.  For the last 5 years Mike has been the Maintenance Engineering Coordinator for Southern Downs Regional Council.

Keynote: The criticality of people in the sustainability of infrastructure management service delivery in New Zealand. Ross Waugh

Everyone in public works service delivery knows about the skills shortage.  It is about to get a lot worse.  The problem and the solution are found in the Maori phrase He tangata, it is the people.

It is increasingly recognised that we are facing a major Engineering skills shortage in NZ.  The reality is that this skills shortage is much wider than just engineering skills and is across the whole stack of skills needed to deliver public works services to our communities.  This is becoming a core issue in our ability to sustainably deliver public works service levels in NZ, and is projected to get progressively worse over the next decade.

This presentation and accompanying paper will review the size and breadth of the skills shortage.  An overview will be provided of the current range of education, industry and government initiatives in place to address the skills shortage.

The infrastructure management and service delivery impacts of the skills shortage will be unpacked including impacts on risks, quality, sustainability, procurement and service delivery cost. The adequacy of current responses to the industry skills shortage, the role of technology, expert systems, artificial intelligence and examination of possible additional industry responses will conclude the presentation.

Ross Waugh is the founder of Waugh Infrastructure Management and is an asset management and systems integration specialist with over 30 years’ experience in municipal infrastructure asset management and engineering.  Ross has been consulting in infrastructure management for 20 years this year, in the areas of transportation, utilities, community facilities, buildings and property.

 Behaviour – a key challenge for our infrastructure
Hayley Tregoweth, WSP Opus

A key way to change people’s behaviour is to change what motivates them. This presentation discusses how our personal views affect our decisions and gives examples of processes already in place at an industry level that help to align our behaviour with community goals, including NZTA Greenroads certification, MauriOmeter and the Infrastructure Sustainability Council of Australia’s IS rating tool. It introduces an idea of a new model called PRISE which considers People, Resilience, Innovation, Sustainability, Environment, with the aim to encourage fundamental changes in behaviours, at every level of society, including the individual, to benefit our communities

Hayley has 6 years full time experience. She joined Opus as a cadet in 2010 completing the NZDE while working full time for three years. Since 2013 she has completed a Bachelor of Civil Engineering while working part time with Opus.Her experience includes working overseas designing gravity sewer systems in Fiji.

Advances in concrete product technology
Ali Mobeen, Hynds Pipe Systems

In recent years manufacturing of concrete products has been affected by alternative materials. To combat this concrete product and manufacturing technology needs to advance.

Restructuring of the concrete product industry has continued at pace in many countries, largely accompanied by the increase of production capacity; in many cases market players with substandard product quality have been forced out of the market. However, this consolidation of markets has led more to price competition on a company level than to quality competition on a product level. These conditions would tend not to support the growth of the industry and potentially favour suppliers of alternative materials.

For concrete products to retain growth in the market, it needs to evolve using new technology and cost-effective manufacturing processes.

This paper illustrates how Hynds are using new technology to increase efficiency and quality of concrete products and how they will be introducing this in New Zealand.

Mobeen Ali is the Concrete Drainage Products Engineer for Hynds Pipe Systems Ltd and has been working for Hynds for over 4 years. Starting in the Graduate program, he has gained experience working in many parts of the business and has progressed to manage the Hynds Drainage product range.
For the last three years Mobeen has spent the majority of his time educating the drain laying industry on the correct installation of Concrete Pipe. So far, he has helped to train over 750 people nationwide from Whangarei to Invercargill.
In the last year Mobeenâs time has been spent on the new Hynds Concrete Factory located in Pokeno where he has been working with key council members to promote the new technology and products that will be available in the upcoming years.

What does wastewater system resilience look like?
Behrooz (Bruce) Balaei, WSP Opus

Failure of wastewater systems not only causes difficulties for the residents and critical users, it but also can have adverse impact on the environment. This paper outlines a framework to address wastewater resilience based on its robustness, rapidity, and contingency measures. A case study is presented discussing the application of this framework to Wellington’s wastewater system. Wellington’s wastewater system vulnerability was assessed. Pipes and pumpstations were ranked based on the combination of their vulnerability and criticality in terms of the number of user being served. Contingency measures were proposed for critical pipes and pump stations to minimise the adverse impact of wastewater overflow on the community’s health and environment. The framework provided an insight into the resilience of existing network and enabled Wellington Water to prioritise their renewal projects to enhance resilience cost-effectively. This framework can be utilised by other local authorities to foster their 3-water resilience under limited budget.

Behrooz is a Water Asset Management & Resilience Engineer at WSP-Opus. He has 9 years of experience in the disaster management field focusing on infrastructure resilience, damage estimation, mitigation planning, risk reduction, and asset management. He studied his M.S in Disaster Management at the University of Tehran in Iran. Having worked at the Tehran Disaster Mitigation and Management Organization (TDMMO), he has been to several disasters and gained a wealth of experience. Behrooz has been working on water supply systems resilience to determine the technical, organisational, social, economic, and environmental factors which affect water system functionality after an earthquake in his PhD journey.

Learning from our past to navigate our future
Pam Wilson, Calibre

There are many different perspectives on what reform means for the communities that we live and work within.  Collectively we are navigating a pathway through reform in a manner that is not dissimilar to the pathways that we may navigate individually in our own careers.  We identify goals to strive towards and we adapt our career paths as we develop and react to the challenges and uncertainties of what the future of our industry looks like.

We each have different perspectives that may shape how we adapt to future reform.  Should we be connecting the dots of our own pasts in order to put new perspectives on how we collectively move forward on the journey of reform?

 Pam is a Water Engineer at Calibre and has over eight years’ previous experience working for contractors and local councils throughout New Zealand.  Pam has experience in the three waters sector across operations, maintenance, contract management and high level design.
