Current as at 24th Mar 2016Asset Management

Are our assets not performing, or is it us?Presenters & authors: Tony Anderson & Priyani de Silva-Currie – Calibre Consulting LtdJust-In-Time, Run-to-Failure, Sweating the Asset, Deferring Expenditure Hands up if you can relate! These terms are ugly for people who plan for the future, but we're using them in modern and brave asset management departments' around the country. What's really going on out there people? Two adages to consider 'why put off for tomorrow what you can do today' and 'a stitch in time saves nine'. Are these wise words still relevant in today's asset management practices? There's a collective need for improved understanding.Tony and Priyani will investigate the following concepts in an interactive session designed to stimulate group discussion: If the goal post has moved, what does lifecycle management planning look like today? Are your programme targets too ambitious, too many new deliverables + carryovers? Can you afford to fund your renewals programme? Is the funding gap too large to fill? Did the policy, engineering and finance teams talk early in the process? Where have all people gone? Do you have enough delivery agents on the ground to

implement your asset management work programmes? You know what's just around the corner - legislation changes, demographic change,

centralisation, and environmental impacts. Just do it! Why New Zealand needs a consistent framework for stormwater and land drainage.Presenter & author: Liam Foster – OpusThe latest position paper from Local Government New Zealand[i] calls for strong sector led approaches to improving the asset information base and service delivery. Furthermore, it specifically identifies what has been long suspected that further investigation into the stormwater sector is required and now finally, proposed. Twinned with upcoming future National MetaData Standards initiatives, an opportunity exists to provide the sector leadership required to collate the data necessary to build effective and efficient responses to face the many challenges our communities face in terms of affordability, ageing infrastructure, climate and demographic changes. The paper seeks to lead a clarion call for why New Zealand needs to focus on why undertaking consistent condition assessment across its stormwater, land drainage and flood management infrastructure will deliver huge benefits. These include the ability to allow for follow up delivery of informed risk-based asset management approaches to help prioritize capital investments. This presentation details the process of obtaining stormwater asset data, provides examples of the data analysis process, and showcases a series of international Condition Assessment Frameworks from Europe, the US and across the Asia Pacific region (including IPWEA's updated Practice Note 5) to signpost a potential way forward for New Zealand[i] LGNZ 2015 - Improving New Zealand's water, wastewater and stormwater sector - A Position Paper.

Amps – to infinity and beyond?Presenter & author: Colin Gerrard - Aecom

Asset Management (AM) practice has matured over the last 20-30 years, including formation of AM focus groups, development of AM guidelines and ongoing maturity and improvement in AM practice. Although Asset Management Plans (AMPs) have continued to develop so they now provide a valuable tool for communication and to enable organisations to meet their objectives, are they really relied upon as a vital tool, or are we stuck in a groove?In this paper, Colin will review how AMPs have developed and discuss where we can take AMPs to provide maximum benefit to organisations and customers. Specific focus is on local and IPWEA NZ 2016 Abstracts, via stream. /26

international practice including the role of the AMP, content, the effect of mandatory prescription and the interaction between AMPs and Strategic Asset Management Plans (SAMPs).Key points presented in this paper: A high level review of Australasia's path to current AMP maturity. How we can innovate and adapt AMPs into the next generation of AMPs, including online AMPs

and incorporation of the best elements from ISO 55000, big data, predictive analytics, better business cases etc.

Key differences between AMPs and SAMPs and how these should be used in union to achieve excellence in Asset Management.

Supercharging the Management of a Forward Works ProgrammePresenter & author: Scott McIntyre - GHD

With an opportunity to challenge the status quo, and achieve a significant step-change improvement to replace the existing data management methodology, GHD and Auckland Transport have collaborated to develop an innovative system for the management of the renewals forward works programme [RFWP]. The RFWP System has created a live forward works programme that is updated daily, with a comprehensive and rich data environment and bespoke features to address specific business requirements. The benefits include the tracking of detailed intelligence on programmed works throughout the works lifecycle, data-driven insights and processes to facilitate the completed works reconciliation process, and enabling further downstream spatial and analytics opportunities. With Auckland Transports' existing investment in the platform, the RFWP system has been designed and embedded directly within RAMM. The foundations of the system include a core dataset built with user-defined tables, a framework of SQL code supercharging the QA management and reporting functions of the system, and direct integration with RAMM Contractor.

Innovative stormwater treatment asset conversion at Auckland motorways Presenter & author: Peter Mitchell – Auckland Motorway AllianceCo-author: Rob Hannaby The New Zealand Transport Agency's Auckland Motorway Alliance (AMA) maintains and operates the Auckland motorway network and is dedicated to improving the motorway experience for customers and stakeholders. Our focus is delivering a safe, efficient, and reliable network.Sandfilter maintenance and operational delivery requirements exposed our customers and operators to significant safety risks. These safety risks required traffic control measures that resulted in a loss of network efficiency and availability. A NZ Transport Agency "Think outside the Box" award winning, innovation project involved the conversion of an unsafe and inefficient Stormwater treatment device namely a Sandfilter into a StormFilter, is a great example of how we 'adapt', 'innovate', and 'flourish'The innovative conversion of a Sandfilter into a StormFilter results in a number of benefits including:

Asset data visualisation key to job management & emergency responsePresenter & author: Helen Ramsey - Downer

IPWEA NZ 2016 Abstracts, via stream. /26

Modern Asset Management Systems and Tools are about reducing the friction between the data and users so that engineers can focus on improved solutions. This is never more important than during an emergency when accurate and timely information needs to be shared.

Our advanced works management systems and dashboards allow for the visualisation and active management of individual jobs. Giving transparency of what is unfolding across a network in a timely way and the extent of issues. Speeding up the process of reporting to all key stakeholders. This allows the tough calls to be made early during an emergency with timely information presented to decision makers. It also supports the day to day management where reactive work volumes are significant.

During 2015 Downer had two key examples where these new systems and dashboards added significant value to our operations and maintenance contracts due to the high volume of emergency and reactive work.

Watercare Contract commenced July 2015: This is the largest water contract in New Zealand with an average of 3500 reactive jobs dispatched per month.Wanganui Civil Defence Emergency event June 2015: The largest flooding event recorded to hit the Wanganui network, with rivers rising to over 9m above normal levels, causing significant devastation. The team managing over 2,000 separate slip/dropout locations, numerous drainage system failures and bridging issues.

Strengthening New Zealand’s creaking infrastructure network: 120 billion reasons to think about asset managementPresenter & author: Jeff Roorda - TechnologyOne

With findings from "The Thirty Year New Zealand Infrastructure Plan 2015" suggesting that New Zealand's ageing infrastructure networks will face significant challenge to become resilient, now is the time for infrastructure owners to implement comprehensive asset management strategies and systems to ensure our networks continue to provide the required levels of service we need. As a key infrastructure owner in this equation, local government has a key role in managing and investing in the country's major infrastructure - 120 billion dollars worth of it to be exact (and growing).So, how do we make better investment decisions in the future to ensure we deliver the services we will need and effectively manage our existing assets?This presentation will explore the benefits of taking an enterprise approach to asset management and how having the right decision support information at your fingertips will put you in a position of strength to respond to the nation's mounting infrastructure challenges.In this presentation, we will explore:

The importance for strategic asset management to have a strong technology base The importance of good systems to manage your asset data The benefits of having all information about your assets accessible, a single source of truth Translating asset information into plain English for your key stakeholders

Innovative asset management for pipe infrastructure renewalsPresenter & author: Lenard Smythe – Timaru District Council

This paper outlines Timaru District Council's approach to physical condition based renewals with utilisation of data sources and management of data sources to enable a balanced renewal profile that suits the districts specific circumstances.Renewal of ageing infrastructure in New Zealand is traditionally based on an estimated remaining life value. Timaru district council have implemented a failure based renewal program across water, sewer and stormwater assets. Consideration of what an asset failure is enables assets to be fully maximised and potentially save millions of dollars.This paper will step the reader through what TDC have done with a particular focus on water mains, both urban and rural. The findings have so far revealed some interesting patterns of failure including: Everyone considers what a failure of an asset is differently and having a failure stand point for

different criticality assets is important


Installation years have an impact on asset lives. Different pipe diameters with same material have different asset lives Capture That! – The No-hassle Data Collection Tool For Rockfall Hazards On Your Road Network…and More.Presenters & authors: Jonathan Claridge & Matt Barnes - OpusDeveloped by Opus International Consultants Ltd (Opus), 'Capture That!' is an information and data collection website that can be used both by the assessor in the field and by the client to input and reference rockfall hazard data on an entire network including photographs, site history and planned remedial measures. New Zealand road networks are extremely vulnerable to rockfall due to geological conditions and high intensity weather. A proactive approach must be taken to identify and mitigate potential hazards as proven by several high profile landslips and crashes over the last several years that have wide reaching social and economic impacts. Through Capture That! efficiency, accuracy and reliable storage of data is improved and the client is able to access site data including inspection records on the day of inspection and prioritise forward workload on a clear and easy to use website. The need for cumbersome paper records is removed and data can be accessed by users on desktop and tablet devices, online and offline, at any location. This presentation will: Demonstrate the assessor side of the website Demonstrate the client interface side of the website, including the custom reporting

functionality Allow 5 minutes for Q&A The tool can also be easily modified to collect and display any type of data on the network, from road safety improvement works to culvert inspections

Reporting Onrc Measures: Some Tips, Tricks And GuidancePresenter & author: Mike Tapper - Beca

The Roading Efficiency Group (REG) and NZ Transport Agency have released the One Network Road Classification (ONRC) performance measures. These are now live for reporting with the aim to have full reporting in place for road controlling authorities for the 2018/21 Long Term Plan (LTP) submission. In conjunction with the measures is a shift from "funding" to "investment", a focus on customer outcomes and building business cases. The performance measures have been determined to provide data around measuring the success in achieving these outcomes.These measures incorporate a series of 13 customer outcome measures, 50 technical output measures and 13 cost efficiency measures. This is a new approach for RCA's and the hard task of fully implanting these measures is starting in earnest. This paper will provide some guidance to the context of the measures to enable RCA's to understand the background of the measures. It will provide the philosophy as to how the measures were developed to support understanding of the intent behind them. This will flow into guidance on reporting the measures. The author will then discuss and recommend some tips and tricks to meeting the reporting requirements.

Earthquakes – we do not know when they might occur but we can prepare for themPresenter & author: Philip McFarlane - Opus

This paper describes research into the seismic response of underground infrastructure following the Canterbury earthquakes which has been sponsored by the Ministry of Business, Innovation and Employment. The research findings are being incorporated into a set of guidelines that will enable practitioners to assess and improve the resilience of existing and new buried utilities in order to limit damage to manageable levels that enable communities to bounce back from seismic events.The paper describes the key findings of the research and provides an overview of the guideline documents. Guidance is provided that will enable practitioners to:

Identify the sections of networks that are vulnerable to damage, to assess the amount of damage likely to occur and estimate the levels of service expected after an earthquake


Identify measures to improve resilience of existing networks. This includes the development of response plans and capital works to improve the robustness and redundancy of the system and to make it easier to restore service after an event. Direction is given into how to incorporate these activities into asset management planning.

Determine how restore a network following an earthquake and to assess the long-term implications of the damage sustained.

Design and install new infrastructure that provides an acceptable level of resilience.

Turning the supertanker – implementing a common level of service and performance framework for New Zealand roadsPresenter & author: Julie Muir – Central Otago District Council

This presentation outlines the experience of the Road Efficiency Group ONRC Partnership Manager in working with Local Authorities across New Zealand to implement the One Network Road Classification Level of Service and Performance Framework in preparation for the 2018 Long Term Plans.This presentation will discuss how Councils are adapting to this change, the extent to which the framework is changing traditional approaches, and characteristics of the organisations which are championing this change. It will also identify challenges Councils are facing along the way, support that has been required to facilitate the change, the response from the Road Efficiency Group to address issues and provide guidance, and innovations that are occurring to meet the challenges.Finally the presentation will provide real experiences of different Councils that are well along the process of applying the framework, how they expect this to impact on their conversations with their elected members and communities regarding level of service and funding, and how they are using the ONRC as a toolbox to enable smarter asset management which will allow them to flourish in the future.


Best PracticeI don’t believe it! – common mistakes made when interpreting New Zealand’s standard construction contracts Presenter & author: Duncan Halliwell – Kensington Swan

When a Project goes well, it goes fine. When it stops going well the contract terms are usually the first port of call. However, despite New Zealand's standard form NZS3910 conditions of contract being widely used on many projects in the public sector, there are still a surprising number of popular misconceptions as to how some of the key clauses actually work. Misunderstanding the contractual position can lead to unnecessarily prolonged arguments and in the worst case a nasty surprise before a judge or adjudicator. This paper seeks to highlight some of the major misconceptions that keep cropping up both in standard contract terms and common amendments, explains what the position actually is and suggests ways in which overseas standard forms deal with the matter more effectively in a way which New Zealand may wish to take on board and adopt as more commonly held practice.

Effecting a national safety culture - stand in the gap -Presenter & author: Dennis Henry - Downer

Highlighting the personal costs of workplace injury, Downer New Zealand has embarked on an H&S philosophy of 'mates looking after mates'.Presented by Wiremu and Marella Edmonds to over 4,500 people around the country, Stand in the Gap (SITG) is part of a wider H&S program to bring about a culture change that ensures people go home safely at the end of every day. The H&S philosophy is about developing a 'want to' culture of personal and collective accountability. Through positive recognition and a generative safety culture, Downer is working to embed this philosophy in everyday working life so employees are living and breathing good H&S practices because they want to, not because they have to. SITG provides us with the emotional and personal connection that will engage with our front line leaders and entire workforce, with a compelling reason to take action that proactively identifies hazards and mitigates risk, and sets up the platform for change.

The intellectual property tug of war - protecting ideas in tenders and contractsPresenter & author: Jenni Rutter – Kensington Swan

There's a tug of war going on. Tenderers want to include their best innovative ideas in tenders, and increase their chances of winning projects. But no contractor wants to see a competitor take those ideas and run with them if they don't win the tender. Project owners want to see the best ideas put forward, so they can make an informed choice. But they don't want to be looking over their shoulder when the project kicks off, worrying about IP. Who wins this tug of war? Is there a middle ground?My paper will cover the often misunderstood fundamentals of intellectual property including copyright, designs, inventions and confidential information. I will talk about the line between ideas and the output of ideas, and why you can protect one but not the other. I will cover some of the risks of co-owning IP and the difficulties of ring-fencing background IP from project IP. I will talk about possible practical solutions that may help us find middle ground. My talk will be of interest to anyone working in the project space - engineers, planners, architects and all those with an interest in innovation.The three key learnings from my paper and presentation will be:

Understanding the difference between ideas and protectable IP How to secure ownership of IP and structure your contract to protect your interests Meeting in the middle - practical solutions to the tug of war


InnovationDriver of change - inspiring innovation in asset management and network planning through disruptive technologyPresenter & author: Erik Barnes – Auxilium LtdCo-author: Thomas KeiferNew Zealanders are hooked on driving. We have 2.3m licensed cars for a population of 4.7m people. 77.5% of kiwis travel to work by car and 80% of seats on the road are empty. New Zealand is also accustomed to developing roading infrastructure and making investment decisions based on traditional responses to network demands. This is an increasing challenge when our demand modelling has been noticeably inaccurate since 2005 (MoT) and expectations and land use changes continue to grow.The problem of heavy car usage, lack of parking space, congestion, and our need to ensure social cohesion and connections between our communities has been the domain of traditional roading solutions based on old paradigms. But are traditional responses the best way forward for our future? Can we ignore the advances of non-roading solutions? Disruptive technology is changing the behaviour of road users and holds significant value for transport planners, engineers, and asset managers. The use of ride-hailing and ridesharing mobile applications are connecting people and enabling shared economies that help reduce these problems and promote the connection of our communities. Looking at mobile technologies like the ride sharing mobile application, Chariot, we explore the potential of disruptive technologies to reduce the number of single drivers in cars, decrease traffic congestion, promote connected communities, and reduce carbon emissions. Ultimately leading to changing how we look at transport solutions to demand issues, increase customer levels of service and decrease costs to manage our transport networks. Drive the conversation with digital: lessons in community consultation for the internet agePresenter & author: Molly Campbell - GHD

Digital technology can be a local government's best friend or its worst enemy when it comes to community engagement. Social media can turn a negative comment into a front page news story overnight (or much faster). Citizens expect information immediately and at their fingertips. Information can be complicated and misconstrued.How can we turn these risks into opportunities? As the saying goes, if you can't beat them, join them. We work with local government and the organisations they work with to drive the conversation with digital by:

Creating and curating online public conversations Collecting, managing and actually informing decisions with real-time data Simplifying and visualising your messaging with animation and graphics

Digital community engagement means reaching people more efficiently, effectively and right on the devices they spend the most time. The opportunity to innovate has never been greater. Adapting together with citizens as they adopt digital technology is the community consultation of the future, making engagement an ongoing priority that informs the important development decisions that shape the places we live.

Roadroid smartphone applicationPresenters & authors: Roy Clearwater and James McCallum – Southland District Council

RoadRoid smartphone technology is the way of the future providing roughness surveys and data collections for sealed roads, unsealed roads and footpaths. The cloud based Swedish technology is very easy to use allowing large amounts of data to be collected and then analysed very quickly, with data being available within an hour of uploading.

This presentation will outline the use of the RoadRoid application and its ability to record roughness data for analysis on the unsealed network in the Southland District. It will show first-hand experiences of the application including limitations and issues addressed during the trial phase. We will show data correlation with WDM high speed data to highlight the accuracy and consistency RoadRoid provides. The presentation will then go on to show other uses the


application can provide using the Speed and Altitude functions, including monitoring driving behaviour of visiting drivers.

A lot of presentations have covered what RoadRoid is and how it works in recent times. This presentation will now go on to the next stage and cover how Southland District Council is going to manage the large amounts of data and use the application most effectively to gain great coverage and improve the way we maintain our unsealed network.

Auckland harbour bridge: meeting environmental challenges sustainablyPresenter & author: Kat McDonald – Total Bridge Services

Since its construction in 1959, and its widening in 1969, the iconic Auckland Harbour Bridge (AHB) requires regular maintenance of the protective coating systems; to minimise the effects of corrosion on the steel substrate in a marine environment. This activity results in the discharge of contaminants to sensitive air, land and water receiving environments around the Waitemata Harbour. Changes to the current AHB Environmental Resource Consent and concerns from the Auckland Council, required the authors to undertake an innovative and adaptive approach toward investigating and identifying ways to reduce the contaminants discharged. This paper summarises the environmental issues posed by the AHB maintenance activities, the local regulatory environment, and the multi-disciplinary approach that was used to develop an optimised maintenance strategy; to provide corrosion protection within a restrictive environmental protection backdrop. It also discusses the review of the existing coatings, and maintenance regime, including the selection of alternative coating systems, which avoid the need for abrasive blasting, further reducing the environmental impact of maintenance painting.


ResilienceHow resilient is my network? – network earthquake resilience modellingPresenter & author: Marcus Gibson - BecaCo-authors: Richard Young, James Gunn & Mark ChristisonEarthquake damage and compromised functionality can impose significant stress on service networks. Resilience modelling can assist asset owners in developing a prior understanding of likely performance and the consequences for a range of synthetic earthquake scenarios and base assumptions. Extensive damage to the water supply and wastewater networks in the Christchurch suburb of New Brighton and subsequent repairs thereto has provided valuable data to support the development and validation of a new theoretical resilience model within a GIS spatial analysis environment. By modelling a range of effects and consequences of strong ground motion and consequential ground deformation on network elements, the risk to the network can be estimated through fragility equations.This paper will explain how asset management decision making can now be enhanced by output from this new resilience modelling tool. The benefits flowing from resilience modelling include;

An improved understanding of a networks seismic performance Rapid desk top sensitivity assessments given a range of scenarios can inform asset

owners on the severity of consequences and relative performance of individual network elements

Key areas of vulnerability can be identified and programmed for focused mitigation Enhancing the resilience of water and road tunnels with a focus on the wellington regionPresenter & author: Eleni Gkeli - OpusCo-authors: David Stewart & Pathmanathan BrabhaharanThe Wellington region has a number of water and road tunnels, to efficiently convey critical lifeline utilities in an area of rugged terrain. The often aging tunnels are subject to deterioration, hence require monitoring, stabilisation, assessment and strengthening to ensure operational integrity and resilience to earthquake and other hazard events. Authorities in the Wellington region and elsewhere, have been supported by Opus in managing the risk in the tunnels, through periodic inspections to identify key vulnerabilities. The authorities prioritised maintenance and stabilisation works for the tunnels through the inspections results and assessments of risk and potential consequences of failure. Best practice investigation and strengthening techniques were applied in some tunnels to ensure cost effectiveness. The paper presents case histories that highlight the value of geotechnical inspections in understanding risks, and how these directed mitigation solutions. Case histories include the retrofit works of the 3.5 km long unlined Orongorongo water tunnel, the strengthening of the substandard concrete lining of Carey's Gully stormwater tunnel at the Southern Landfill, and the seismic strengthening of the Hataitai Bus and Mount Victoria Road tunnel portals. Management of the safety risks during inspection, investigation and construction is also presented.

Resilience? What's that?Presenter & author: Mark Gordon - Aecom

Our communities increasingly depend on infrastructure and technology, with change happening at a pace that can only get faster. At the same time our physical networks are ageing, in many cases becoming more prone to failure, while the risks from natural and man-made hazards are escalating globally. What are we as asset managers doing to embed resilience into business as usual asset management planning?A lot has been learned from events such as the Christchurch earthquakes, and NZ is part of an international community of interest seeking ways to make both our infrastructure and our organisations more resilient. Resilience is one of the Government's key themes, reflected in the National Infrastructure Plan.Mark's paper will share his learnings and insights gained over the last 20 plus years, tying risk, resilience and asset management together, highlighting along the way interesting findings from the work of academia in Christchurch.He will provide a topical overview of current initiatives in the "Resilience" space, including new content in the IIMM 2015, the Economics of Resilient Infrastructure model (MERIT), 100 Resilient


Cities, and learnings from the national Lifelines community, all with the objective of fostering a commitment to embedding resilience thinking into asset management planning processes.

The art of base isolationPresenter & Author: Ben Hardy - Fulton HoganCo author: Grant Wilkinson - Ruamoko Solutions

Learnings: Retrofit of Base Isolation is Sustainable Retrofit of BI is cost effective Many aspects of a conventional building's design present substantial hurdles to BI retrofit,

but in this case these can be overcome with an innovative design team.

The earthquake resilience of the Christchurch Art Gallery building has been dramatically improved, not only to meet enhanced building code requirements but to restore the confidence of international art lenders, touring exhibitions and their insurers in knowing that the Gallery is a secure place for their precious artworks. The building's structural form has been adapted by the retrofitting of a triple-pendulum-bearing base isolation system. This is a very sustainable solution as, unlike so many other buildings in Christchurch, it did not require the building to be demolished and rebuilt.Base Isolation has proven to be a cost-effective solution as the upper floors required no strengthening to meet the revised code due to the bearings reducing the earthquake accelerations. This also enabled the Art Collection to remain within the storage rooms of the building throughout the project.Many aspects of the original building's design presented substantial hurdles to the retrofitting of a base isolation system. However in the case of the Art Gallery, challenges such as lift shafts, basement plant rooms, and vehicle access ramps have all been overcome in remarkably innovative ways.Now, Art and Culture will again flourish in Central Christchurch.

Revitalising LeithPresenter & author: Chris Jobson - Downer

The Leith River runs through the middle of Otago University in Dunedin. This section of the river was contained in a normal concrete channel with a series of weirs and bends to manage flow which Regional Council identify as flood risk. A capital works flood protection improvement project was tendered to improve flood risk within University grounds, improve access to the river for recreational purposes and improve general aesthetic environment.The project involved the removal of the existing concrete channel structure and creation of a new tiered embankment with walkways, stairs and landscaping that could withstand flood water.During the construction phase of the project a flood ran through the site. Thankfully, due to prior warning, all major equipment was removed from site with no significant damage.On completion of the project another flood occurred which tested the final construction. The landscaping and walkways withstood the flood conditions well with only minor debris on handrails to be cleaned away. During the flood locals also enjoyed kayaking in the river and easy access into the river.The new landscaping has created a great environment to University staff and students to enjoy. A very successful outcome for both the Regional Council and University.

Leaders as learners. We all learn from experience -or do we?Presenter & author: Therese La Porte – NZIM Southern Inc

To build resilience, innovate and flourish in a changing world, leaders need to be able to learn from experience, harvest the learning and use it as the foundation for future growth. Yet there is ample evidence that leaders fail to learn either from their failures or more interestingly from their successes. In this session we will explore the phenomena of experience, learning and everyday creativity. We will blend these three concepts together to create a framework to build our awareness of what is needed to grow and flourish in the workplace. We will share ideas on why time consuming activities like 'work around' persist and how to redirect everyday creativity. We will play with the concept of 'flick or stick' and explore the behaviours that no longer serve us


well, identify how to minimise or change them, while retaining vital and positive performance that will support leaders and teams to create a new future. The nitty gritty of making grit removal resilient at cwtpPresenter & author: Raelene Stewart - BecaCo-authorz: Greg Offer & Lee Liaw The Christchurch earthquake sequence of 2010/2011 resulted in widespread liquefaction and a dramatic increase in inflow and infiltration into the sewage network. Large quantities of grit were carried into the Christchurch Wastewater Treatment Plant (CWTP) both immediately after the earthquakes and later during high rainfall events. While the CWTP continued to operate throughout, the five grit removal tanks and seven associated primary sedimentation tanks at the CWTP were frequently overwhelmed by the volume of grit coming into the plant. Grit flowed into downstream parts of the process where it accumulated and caused damage to equipment.A review of options to improve the plant focussed initially on vortex grit traps, as the default modern technology option. However there were concerns about construction risks and uncertainty around the response of vortex grit traps to shock loads of grit.Instead a resilience project emerged based on optimising the existing asset by decoupling the grit tanks from the primary sedimentation tanks. This paper describes how simple and innovative adaption of the existing plant and structures improved operational flexibility, resilience and the ability to cope with high grit loads, while minimising both operational and construction risk and capital cost.

Keeping our roads openPresenter & author: Stuart Woods – NZ Transport Agency

Over recent years, numerous natural events such as Christchurch earthquakes, Manawatu Gorge slips and Northland floods have resulted in closures or reduced availability of our State highways. A Transport Agency national "Resilience Project" is responding to both concerns about social and economic impacts of such closures on road users and all of New Zealand, and opportunities from changing business practices such as the recent Network Operating Contracts, the Business Case approach and One Network Road Classification.The Resilience Project's goal is to maximise State highway network availability for our customers and improve the experiences people have on our highways. To achieve this, the Project team will facilitate and provide guidance, tools, templates and information to enable our teams and partners to work with resilience issues confidently, consistently and within a Best Practice framework. The Project acknowledges that there are already many excellent measures and practices in place at the Transport Agency that to cope with disasters and extraordinary events, and intends to build on these. This paper will present progress that the project is making in three work-streams related to Business Continuity Plans, Emergency Response Plans, and Asset Planning and Development processes. It will also present project outputs that will be of interest to all professionals involved in resilience-related work.

Builders crack – the foundations of innovation and building community leadershipPresenter & author: John Sargeant – South Taranaki District Council

Council owned earthquake prone buildings provide an opportunity for local government to lead by example in managing positive change. South Taranaki DC currently has six significant public buildings identified as being earthquake prone, with potentially more to come. Rather than wait for the inevitable problems, STDC has shown courageous leadership in managing the sudden closure of earthquake prone facilities such as theatres and halls with little or no fuss.This paper will outline the process of how STDC closed facilities at very short notice at a very busy time. It will discuss how the buildings future will be managed with the support of the users and which building may have to go.Best practice is shown with modelling the future needs for specific buildings set against the political and social pressures of managing community expectations in small towns.


It is a story of innovative thinking and future proofing assets by adapting to change through the constraints of legislation while managing the needs of communities.This story will resonate with Districts who are close to their public and work directly with users who are passionate about their facilities. This will also include discussion on some innovative approaches to strengthening iconic public buildings.

From disused off-ramp to attractive urban space: The Nelson Street off-ramp/Canada St bridge projectPresenter & author: - Stephen Cummins GHDKey points:

Process for delivering the Canada Street Bridge project under significant time-constraints, Design challenges of the project; and Monitoring of usage of the new link- who's using it, why and has the link created a

commuter mode shift? Project significance: The Nelson Street Off-Ramp had stood unused for 10 years when NZTA decided to utilise it as part of Auckland's growing active cycling network. The new Canada Street Bridge follows a trend turning redundant transport infrastructure into great urban and active transport spaces (seen also in the Highline in New York and 606 in Chicago, amongst others). Unlike these projects however, it is unique in how quickly it has been designed and delivered. In October 2014 GHD was contracted to undertake design and construction with partners Novare and architects Monk McKenzie completing the bridge design. What would have normally been a 2-year project to design and retrofit/build the structure was condensed into 1 year - and will be delivered by end of November 2015. The prompt delivery of this project involved high levels of collaboration and trust between all project partners, to deliver what will be a beautiful new urban space and active transport link for the people of Auckland.

Adapting decision support to answer new asset management questionsPresenter & author: Theuns Henning – IDSCo-authors: Erik Barnes & Steven FinlayThe past three years has seen some significant changes in the asset management sector of New Zealand. Building onto the Road Maintenance Task Force and a number of other reviews, the sector has been implementing a number of initiatives driving towards more efficiencies within asset management outcomes. Some of these include new procurement options, amalgamated services and better planning techniques. A specific initiative from this work was the One Network Road Classification (ONRC) framework that was developed by the Road Efficiency Group (a joint initiative between Local Government New Zealand & the New Zealand Transport Agency). A desired outcome from the ONRC framework is a more stratified planning outcome of roads that strongly focuses on Customer Levels of Service (CLOS) of the various functional road classes. By having this stratified planning approach a different investment philosophy is developed for the respective road functions. Changes in the philosophy for infrastructure planning has required an adaptation of the decision support system and how it functions. Traditionally, decision support tools such as dTIMS optimised road investment on the basis of different intervention levels for different traffic classes. The traffic volume was again used during the optimisation process through the weighting according to traffic loading. Because the ONRC philosophy is based on other factors, it also encourages planning processes to align priorities to the functional aspects of the road and defined customer outcomes. The figure below shows different considerations and its relative importance given the respective ONRC classes. This paper covers the development work that was undertaken for LGNZ to develop a multi-objective optimisation process for analysing long-term road investment funding needs. It demonstrates this innovative process to be leading infrastructure to flourish according to economic, socio, cultural and environmental considerations.

Consequential OPEXPresenter & author: Thisula Kithulagoda – Auckland Transport


Consequential OPEX is the ongoing spend required to maintain new assets. Defining both the level of service and the method used to model deterioration of assets can significantly impact the amount of Consequential OPEX over an assets useful life.The condition of any asset over time is non-linear. Therefore, the goal is to minimise the overall spend required to maintain the required level of service at any point in time. This means that consequential OPEX is also non-linear and is predicted to have a direct inverse relationship with the deterioration curve. The ability to develop a relationship between decay curves and the costs required in achieving the necessary level of service will allow greater accuracies in determining the consequential OPEX. This knowledge will provide asset managers more opportunities to minimise spend but maximising network preservation. This paper will explore the process taken by Auckland Transport in developing and modelling consequential OPEX for capital works and current asset.

What’s the new NZ Infrastructure Procurement Diploma all about?Presenters & authors: Caroline Boot – Clever Buying & Helmut Modlik - Connexis ITONZ infrastructure procurement is patchy. We all know that it’s excellent in some areas, and decidedly deficient in others. With our sector’s responsibility for spending billions of public dollars each year, and huge pressure on our engineers to achieve more with less, we cannot afford to have poor decision-making processes in government procurement of infrastructure capital and maintenance projects.The initiatives taken by a working group for procurement qualification reform have given us the tools to extend the very best in practical procurement training and qualification to all infrastructure clients throughout New Zealand. Smarter procurement could save many millions from our infrastructure budgets. Our challenge is to implement better procurement methods across the board, so that public funding decisions are fair, transparent, fit-for-purpose and cost-efficient.To work towards this goal, our working group has adapted NZTA’s proven formula for procurement qualifications; added innovations from the best in world-wide international procurement, to launch this leading-edge infrastructure procurement qualification. In this presentation, Caroline Boot [Clever Buying] and Helmut Modlik [Connexis] will:1. Present the drivers for procurement qualification reform2. Outline the adaptations and innovations made to the NZTA qualification to broaden its focus

and align it with the best in world procurement3. Show-case the brand-new NZ Certificate in Infrastructure Procurement Procedures,

and explain how it will be trained and assessed4. Suggest future developments to strengthen and reinforce the value that this qualification can

add to our infrastructure decisionsThis new qualification is our industry’s key to boosting procurement skills in NZ infrastructure. It will continue to be the requirement for NZTA evaluators of significant projects, but its broadened focus and inclusion of NZ government procurement rules, principles and processes makes this the qualification of choice for all procurement staff.The NZ Certificate in Infrastructure Procurement Procedures will become the benchmark for procurement of all infrastructure, including water, telecommunications, rail, civil engineering, utilities, power, housing, waste, ports, and more.

Innovating age old systems: Bio-engineering for slip and drop-out repairs 12 years on Presenter & author: Robert Coulson – RST Environmental Solutions Ltd The use of bio-engineered systems was common place through to the 1970's and was reintroduced in to the tool box of solutions for slip repairs following the Manawatu/Wanganui floods in 2004. This paper looks at how the structures have worked since 2004 and what the issues around any failures have been. Included are several cases studies showing the successful outcomes on rural roads.Brush-layering techniques using shrub willow have advanced rapidly in recent years meaning that significant re-inforced earth structures can be constructed to control slips and drop outs. They generally cost between 40-60% of more traditional retaining wall systems and are relatively maintenance free.Specific non-invasive species of willow are used, meaning that there is now a lot of flexibility as to where these structures can be placed. New techniques such as the use of a willow raft foundation


to combat soft ground conditions will also be discussed as well as the integration of geo-synthetics in to the wall systems.

A lane for cyclists in a tight spotPresenter & author: Richard Galloway – Memorial Park Alliance Challenge: A protected cycle lane for a constrained inner city environment. A challenge for the Victoria Street Transformation Project in 2015 was to install a cycle lane in a constrained inner city traffic lane environment while fulfilling Wellington City Council's desire to create a safe cycling route and ensure continued support for the high levels of public transport use in the Capital. Solution: Memorial Park Alliance devised a solution for a protected, separated cycle lane between the kerb on one side and car parks, peak traffic clearway and bus stop on the other which the council has used as a trial for future developments.Key learnings:

Education is essential when implementing new conditions; positive reinforcement involving face-to-face liaison with the public being a most effective tool.

Stakeholder engagement is a process, not a one-off, and a series of interactions should be anticipated with interested parties.

Providing a safe and practical lane is likely to increase the level of cycling activity as public response indicates it has made them more likely to use this route.

Results: The design illustrates the practicality of implementing a kerbside cycle lane and a potential treatment where the lane passes a bus stop in a constrained environment. There has not been a significant loss of service for any other user group on the corridor.

Selecting the best model for your road maintenance contractPresenter & author: Chris Olsen – Chris Olsen ConsultingCo-author: Jamie McPherson The Road Efficiency group (REG) has set up the REG Procurement Sub-Group to primarily:

Identify and promote procurement opportunities that will enhance the sectors ability to

obtain value for money. Enable and publish the development of tools, templates and standard methods that will

improve procurement practice and increase efficiency. Build procurement capability amongst RCAs.

This paper explores the value for money opportunities and risks that various road maintenance procurement and delivery models produce, drawing from New Zealand and international experience, in order to provide guidance to RCAs for selecting a model that is right for them given their particular circumstances. A Matrix relating input drivers with procurement models will enable quick comparison of models that best suits the needs of the RCA and provide value for money.

An international literature search was used to supplement learnings from 11 New Zealand case studies covering the following contract models;

Traditional Performance-based, aggregated & bundled Alliances Cost reimbursable, fixed fee Framework/Panels PPPs/PSMC

Appropriate supplier selection processes, methods of payment, and critical success factors for each model are also considered and reported on.

The city rail link’s sustainability journey Presenter & author: Liz Root – Auckland Transport

There is a perception that public transport is inherently sustainable, but delivering new infrastructure can come at an environmental cost even if the delivered outcome provides social, cultural, environmental and economic benefits.


The City Rail Link (CRL) seeks to address this issue and is aiming to set the benchmark for designing, building and operating sustainable infrastructure in New Zealand. From establishing targets and specific criteria to strive for, through to engaging with our contractors to construct in a more sustainable way, this paper will describe the sustainability journey taken by the CRL and the challenges and opportunities in striving to deliver sustainable infrastructure. There will be a focus on the 'early works' of the project for which we have engaged contractors on an ECI basis. Project context will be provided as well as consideration of the implications for future works packages for CRL as well as learnings for other infrastructure projects.

How an organisation adapted into the new NOC environmentPresenter & author: Neil Beckett – NZ Transport Agency

The NZ Transport Agency's Maintenance and Operations Review, carried out in 2013 required a major rethink of how our State Highway Maintenance and Operations activities are performed. Not only did the industry need to make organisational changes, the NZTA itself needed to restructure itself and make significant steps to support the goals of this review.The paper will discuss the key changes following the introduction on the Network Outcomes Contracts (NOC's) from an agency staff point of view and discuss the internal changes that have taken place and the methods used to achieve this step change in an organisation's performance and the challenges we faced.The paper will describe the 4 key roles introduced: Network Managers, Maintenance Contract Managers, Journey Managers and the Asset Manager Integrators.One of the initiatives that helped us transition to the new work environment was the introduction of Knowledge Communities, groups of staff with similar roles sharing best practice, knowledge and driving national consistency.We have managed to demonstrate the organisational is starting the flourish, following the organisation restructure and the stresses that come with these.

Noc noc....who's there?Presenter & author: Nigel Pollock – Downer & Tony Hampson – Tairawhiti RoadsCo-author: Tony Hampson NOC NOC. Behind this door, what will we find? A healthy environment, or something else?Combining The Agency, Local Council, Consultants, Contractors, Local Roads, State Highway and City Maintenance under one umbrella could be considered a test. Catering to the expectations of the stakeholder's journey can take on various meanings and expectations.This will be a joint presentation (MCM from the Principal and the CM from the Contractor) that will highlight the first 8 months of the Tairawhiti Roads Western NOC. The first NOC of its kind in NZ, combining Local Roads, City and State Highway networks in the one contract. The presentation will share the following:

Views from the Contractor and the Client. Relationships between Client/contractor/stakeholders. Individual and joint challenges. Risks - Subsidence sites, geographic isolation. Opportunities. High points and low points. Are there winners and/or losers? Satisfaction levels.

3 key points/learnings:

The importance of collaboration/relationships? Is this NOC delivery working? Why? Why not? Hindsight - Could we have done things differently?

This contract started 1st Oct 2015. The presentation content will develop over the next few months, absorbing the construction season and entering into the winter maintenance season.


Water Supply, Stormwater & Wastewater Sponsored by

Stormwater treatment devices - design considerations and operating implicationsPresenter & author: Troy Brockbank – Stormwater 360Co-author: Kevin JonathanUrban land development has radically altered the hydrological cycle by replacing natural pervious land with vast impervious surfaces. This has led to increased peak stormwater runoff flows and volumes whilst reducing the potential for infiltration and evapotranspiration. This development has also lead to an increase in sediment generating activities and subsequent potential of pollutants being carried by runoff. Polluted runoff can have detrimental effects on the quality of the receiving waterbody. Regional regulatory authorities, in accordance with the Resource Management Act, have imposed policy's requiring land use activities to minimise their adverse environmental effects on water quality, and to avoid, remedy or mitigate the degradation of water by contaminants. Stormwater management devices are commonly used to treat the runoff and reduce the risk of adverse environmental effects by decreasing the contaminant concentrations to below acceptable trigger limits. The majority of devices in New Zealand tend to be designed according to either Auckland Council's TP10 or Christchurch City Council's Wetland, Waterways and Drainage Guide. These documents provide a good general overview of various device performance and treatment applications, however the hydraulic operation of the device is often misinterpreted or unconsidered by designers.Consequently this can lead to flooding within the catchment due to surcharge, under designing the treatment device for the required water quality flows, or at worst make the device inoperative all together. Climate change may also provide future tailwater problems with rising sea levels at coastal outfalls. This paper will present advanced design considerations for stormwater treatment devices and discuss resilient and hydraulic implications on the stormwater network.

Successful approaches to managed aquifer recharge – goal setting, planning, design and executionAuthor: Michael Goff - Beca

Managed Aquifer Recharge (MAR) has been described as the intentional increase of recharge to groundwater aquifers for storage, supply and/or environmental benefit. The objective of this presentation is to communicate successful approaches to planning and executing MAR projects. Success of a MAR project depends on establishment of appropriate goals, planning to meet those goals, careful science based design and dedication to the programme of development. Identified goals for a project are essential in developing proper design and benchmarks for measurement of success. Goals can include disposal of unwanted water, storage of water for seasonal or long term recovery, basin replenishment and recharge for water quality benefits. These goals can be combined in many cases. A detailed understanding of the benefits and limitations of MAR and the project elements should lead to successful goal setting and project outcome. Planning of a MAR project is more detailed in some ways than traditional surface reservoir solutions. Detailed hydrogeological and geochemical understanding is essential. Stakeholder involvement is increasingly important to successful projects especially involving reuse water. Design considerations include availability of surplus water for recharge with regard to timing and quantity, availability of land and facilities depending on selected approach, need for treatment on recovery if applicable and establishment of monitoring for regulatory compliance and early identification of problems. IPWEA NZ 2016 Abstracts, via stream. /26

Execution of the project requires stakeholder buy-in and dedication to the programme. Monitoring must be maintained for regulatory compliance and determination of status with respect to project goals. Technical approaches to MAR are described through the examples of actual projects in place or being developed in USA, UAE, KSA and AU. Significant cost and resource benefits of storage in aquifers over traditional surface storage approaches or development of additional resources is discussed with examples drawn from on-going projects.

National policy statement for freshwater management 2014 – key implications for the consenting of municipal wastewater dischargesPresenters & authors: Garrett Hall & Chris Scrafton – MWH GlobalThe National Policy Statement for Freshwater Management 2014 (NPS-FM) recognises the importance of freshwater resources and sets out to provide a national direction through the management of freshwater bodies across regions. A key aspect of the NPS-FM is the change required to the RMA planning framework to allow each region to implement the NPS-FM by 2025. However, recent Environment Court decisions have highlighted that the NPS-FM will have significant consequences for the consenting of treated wastewater discharges to freshwater and land. This paper reflects on recent decisions in terms of key aspects of the NPS-FM for discharges of municipal wastewater including:

Objective A2 'the overall quality of freshwater is maintained or improved'; Objective A2 'improving the quality of fresh water in water bodies that have been

degraded by human activities and to the point of being over-allocated'; and Definition of 'water quality' versus ecological effects.

Many of these concepts, in terms of improving freshwater quality and 'over-allocation', cause difficulty when considering the process of obtaining consents for the discharge of treated wastewater. This paper will traverse the implications of these aspects of the NPS-FM, from a planning and scientific perspective, for local authorities when obtaining new discharge consents and the need for adaptive and innovative approaches.

Safety in design in the water industryPresenter & author: Kirsty Johns - Beca

In Australia, the concept of "Safety in Design" has been around for a few years, being gradually introduced across the states and culminating in the 2012 harmonised Work Health Safety laws. Since then, fatalities at work have declined. Designers are rightly required to look at their designs and consider the impacts of the design on the health and safety of people coming into contact with it, across the full lifecycle, from construction to demolition. As we have worked through this requirement, our experience has led us to define a process that is efficient and effective for the water, wastewater and stormwater work carried out.This paper discusses various methods of incorporating safety in design into the project lifecycle, in particular those we have found effective within the water industry, and looks at some key lessons, including:

Using the process to improve not only safety but also cost effectiveness of safety solutions Using the process to demonstrate the benefits of improving safety, superseding physical

costs. Engaging stakeholders early in the process to manage expectations of both the process

undertaken and the design outcomes.Where possible, case studies are used and practical examples are given.

How to successfully install cured-in-place-pipe (Cipp) LiningPresenter & author: Dietmar Londer – Auckland Council


The Scarlock Ave Stormwater project comprised cured-in-place-pipe (CIPP) structural lining of a 65m long, 1350mm diameter culvert. Recent conditions assessments indicated that section(s) of this culvert had experienced severe deterioration, posing a high risk of structural failure. The culvert is located in a heavily built up area and due to the high risk of structural failure it required a full structural lining.The location of the culvert and potential stormflows required the installation of the CIPP liner during a 5 day period of dry weather. Delays in the liner supply pushed the installation into mid-autumn, a period of unstable weather with frequent heavy showers.The paper will outline:

The complexities dealing with a 15t CIPP liner The noise and odour issues encountered and how they were resolved The assumed vs actual construction durations and the impact optimistic assumptions

could have hadThe paper will discuss both managerial and technical complexities and how they were overcome to deliver a successful project.

A seismic shift in design – Embedding safety and value into resilient post-earthquake designs for 3-waters infrastructurePresenter & author: Ian Macbeth - BecaCo-authors: Iain Partington, Gavin Hutchison, John MooreThe post-earthquake infrastructure rebuild in Christchurch has provided an opportunity to fully integrate safety in design (SiD) and value engineering into designs. With seismic resilience being fundamental to these designs, there is also a need to balance financial constraints imposed by insurance payments on one hand, with a focus on incorporating whole-of-life safety considerations on the other. These apparently conflicting drivers have emboldened designers to go beyond conventional conservative designs to come up with smart, cost-effective solutions. It has also required clients to be engaged in the journey, sometimes taking them outside their comfort zone. Solutions have utilised unconventional equipment and materials, pared-down structures, novel configurations and innovative repair and remediation methodologies. In some instances, resilience has moved from ‘unbreakable’ to ‘easily repairable’. This paper summarises some of these innovative solutions, using delivered examples from the Christchurch rebuild, as well as one built elsewhere, applying the learnings from Christchurch. It highlights the need to have the right people, from multiple disciplines, involved in projects from the outset; to challenge conventional wisdom in delivering safe, resilient, yet cost-effective, infrastructure for our communities.

Adaptive stormwater – retrofitting attenuation and treatment in an urban environmentPresenter & author: Christopher Maguire – MWH Global

Changing weather patterns and the threat of more intense storms may lead to an increase in nuisance flooding for New Zealand. The current range of Local Government Long Term Plans include significant funding for stormwater, the previously forgotten child. However are we taking an integrated approach to stormwater in our existing urban areas and are we utilising opportunities to provide mitigation? With increasing intensification of development in existing urban areas, how can we increase permeability and treatment of stormwater? Do our current policies and standards improve the existing situation or only mitigate against further deterioration? Do our street scape upgrades maximise opportunities for soakage, detention or treatment? This paper will look at existing retrofit and upgrading examples from New Zealand and internationally to showcase best practice and how we can adapt our thinking to enable our environment to flourish. Delivering innovative infrastructure to provide a cleaner and safer environment for our communitiesPresenter & author: Steve Shortt – MWH Global, Mohamed Imtiaz – Watercare Services & Daniel McKessar or Scott Meehan – Fulton HoganCo-author: Mohamed ImtiazIPWEA NZ 2016 Abstracts, via stream. /26

Each day, Watercare handles around 378,000,000 litres of Auckland wastewater. In doing this, Watercare manages and minimises the impact of their operations on the environment and embeds sustainability into their business.The Kohimarama wastewater pump station which services a dense urban suburb overflows approximately 8 times per year into the Kohimarama Beach, via a local stream. To improve water quality in the receiving watercourse and comply with Air, Land and Water Plan regulations for overflows, Watercare invested NZ$11.5M in new infrastructure.This paper will demonstrate how Watercare, MWH and Tonkin and Taylor (Designers) and Fulton Hogan (Contractor) worked collaboratively to deliver innovative and cost-effective infrastructure whilst minimising the impact on the local community, mitigating project risks, complied with consent requirements and consistently scored a '1' (highest) for environmental audits during construction. The site was a multipurpose environment used for recreational and public activities. This project is showcased as one of engineering excellence.Engineering innovation delivered multiple savings including a New Zealand 'first' with the design and installation of the Biogest® vacuum flushing system. This is a proprietary self-cleaning facility to keep the tank free sewage debris.

Rapid, integrated subsurface ground modeling at Puketutu IslandPresenter & author: Mike Thorley - Beca

Embracing new Kiwi know-how for building subsurface ground models is improving the quality of information and reducing costs. Leapfrog Geo subsurface ground-models facilitate rapid communication and interrogation of subsurface ground investigation data-sets in 3-dimensions. It provides a single repository of ground-investigation data for a range of applications including: highways; wastewater; mining; and water resources. One of the first projects where this tool was used was for the Watercare Bio-solids Containment Facility at Puketutu Island, Auckland. A critical secondary subsurface drainage system beneath the liner of the facility required detailed design and consent compliance approval. The Leapfrog Geo tool enabled rapid compilation of a large and complex tranche of site investigation data, historical accounts of quarrying and filling, and the proposed facility embankment and base grade. The current and future ground conditions beneath the site were rapidly assembled and updated as more data was received. Several operational scenarios were promptly considered to determine where the sub-surface drain would most effectively capture potential leakage beneath the liner. The Puketutu Island sub-surface ground model was readily exported to numerical groundwater flow and contaminant dispersion models; geotechnical slope stability models and to enable [or to CAD for] civil earthworks cut-fill calculations. For the Puketutu Island Rehabilitation Project, utilizing this new software technology:

Improved the accuracy of analyses; Reduced the time to build subsurface ground models and provided timely ground and

groundwater information for designers and regulators; Facilitated collaboration across critical design inputs and enabled multiple disciplines

to work from a common 3-dimensional understanding of the sub-surface environment. Risk and reward - the new economics of flood risk management Presenter & author: Jon Rix – Tonkin & TaylorCo-authors: Tim Grafton, Ian McComb & Campbell LarkingChanges to the current approach of infrastructure planning have been requested through a series of recent think pieces, position papers and plans produced by nationally focussed organisations and agencies (e.g. ICNZ, Local Government NZ and central Government). With a focus on natural hazard resilience (in particular urban flooding) this paper examines opportunities to meet the 30 year Infrastructure Plan request for "a better understanding of the levels of service we want to deliver, more mature asset management practices and use of data, and more effective decision-making that considers non-asset solutions". The traditional local government engineering approach of adopting a fixed level of service is insufficiently flexible to adapt to the risk based, cost-benefit focussed approaches promoted for developing resilience in a cost-effective manner. The paper examines the risk-based, cost-benefit focussed approach for the following three aspects:


Perceived barriers to the risk-based approach, including making recommendations for improved information availability from a high quality, national database.

How the risk-based approach can be used to establish levels of services, including consideration of "tolerable risk" and communication of risk with stakeholders (e.g. rate payers, landowners, asset owners, local council, finance providers, insurers)

Challenges faced for implementation

Shaping A New Best Practice Erosion And Sediment Control Guideline For AucklandPresenters & authors: Bridget Wild – Auckland Council & Michael Parsonson – SouthernSkies EnvironmentalCo-authors: Branko Veljanovski, Kate Dawkings, Hugh Leersnyder, Kathleen Bunting & Campbell StewartSince 1999, the Auckland Regional Council technical publication TP90 (Erosion and Sediment Control Guidelines for Land Disturbing Activities in The Auckland Region) has led the way in environmental management and design guidance for erosion and sediment control across Auckland and New Zealand. After 16 years, amalgamation of eight councils and major technological advancements in the industry, it is time for a major update of this well-used document. Over the past year, Auckland Council has worked together with industry stakeholders to shape a new guidance document - GD05. GD05 seeks to provide a more practical, easy to use and understand document that is up to date with current technology and practices in the industry. Key features of the new guidance document include:

Inclusion of recent advancements in best practice, such as chemical treatment and T-bars for decanting earth bunds

Practical and clear on-site guidance to contractors, including flowcharts, photos, diagrams, checklists and examples

Guidance on specific land disturbing activities such as dewatering and works within the coastal marine area.

Prequalification – An historical view to the futurePresenter & author: Malcolm Abernethy – Civil Contractors NZ

Historically prequalification has been around since 2002. It was introduced to great fanfare as the way to save time and cost associated with the procurement process.The problems over most of this time were and are:

Trust in the data used to prequalify a company resulting in almost all the data gathered when prequalifying being asked for at each tender.

Currency of the data being generally two years out of date because of two yearly prequalification updates and an inadequate performance monitoring method to provide updates

Cost of maintaining a largely manual system of records.

There have been many adaptations of the NZTA system and a plethora of bespoke prequalification systems established by Local Government agencies with most concentrating solely on Health and Safety.The latest iterations of prequalification continue to be largely focused on health and safety but are in reality contractor or supplier management systems. As an industry we must get prequalification back on track and start asking, only once, for the generic prequalification information and score it rather than the current pass / fail approach. The industry and entire country need just one prequalification system or process that provides the foundation for project specific questions.

Monitoring of the river recharge with groundwater schemePresenters & authors: Martyn Cole – Kapiti Coast District Council & Tracey Clode – CH2M BecaCo-authors: Kirsten Fraser, Michael Goff & Nathan BakerIn early 2016 Kapiti Coast District Council's award-winning River Recharge with Groundwater (RRwGW) scheme will have been monitored through two summers. The 78 pages of consent conditions required an extensive network of monitoring sites and supporting systems be set up focussing on four ecosystems:

Waikanae borefield Seven small coastal streams 13 Wetlands Waikanae River.

This paper will describe the setting up of that network and systems, the changes that have been made to the consents to recognise the practicalities both on-the-ground and in the monitoring framework, the results of the monitoring and how this is being reported to the regulator/ stakeholders/ public (e.g a website for the 150 private well owners who are potentially affected), the workings of the innovative Adaptive Management Group, and what the future might hold for more cost-effective monitoring of RRwGW.The three key points/learnings that will be explored and documented are:

Because RRwGW was a novel and innovative water supply scheme, a conservative approach was taken in the consenting, resulting in a high level of monitoring. Council is hoping it will be able to optimise the level of monitoring in the short to medium term, as the degree of uncertainty around the actual effects reduces over time.

How a collaborative and pragmatic approach to the monitoring has resulted in more efficient and effective data gathering and reporting.

How adaptive management can work in practice.

Is cheap real value?Presenter & author: Carey Morris & Tony Harrison - GHDCo-authors: Tony Harrison, Shawn McKinleyAfter less than desirable contract delivery for many years and the premature end of the latest contract caused by unsustainable pricing on their network maintenance contract, Central Hawke's Bay District Council (CHBDC) decided to take a fresh look at how they procured this major


component of their business. The contract developed needed to be flexible enough to deal with changes that would likely come about with the One Network Road Classification coming into effect and the need to balance contractual requirements with shifting level of service delivery.GHD worked closely with CHBDC to develop the request for tender, a robust evaluation and negotiation process. The recommended and adopted procurement method was Quality Based with a pricing model that separated out profit and overhead payment. In a world where cheaper is often considered better it was a bold move to move to 100% quality on a $4m p.a. maintenance contract. This presentation will provide and insight into the reasons behind this change, the process of procurement and negotiation with the successful contractor and how in the quality based procurement process CHBDC are satisfied they received a competitive price that is reflecting a value for money outcome.

Prizes and pitfalls of relationship based contractsPresenter & author: Kristina Hermens – Beca & Wally Potts – Tauranga City CouncilCo-authors: Wally Potts, Gijs Hovens & Mark ChristisonMore local authorities across New Zealand are working in collaboration with professional services providers by entering into relationship-based contracts to help them deliver infrastructure assets and services to their communities more efficiently and effectively. Why are collaborative frameworks favoured over engagements on a project by project basis? Local authorities have to respond to the pressures of constructing or upgrading infrastructure to meet community needs and industry standards, while operating services that are essential to our daily lives. Having a professional services provider that specialises in delivering infrastructure and that can come to understand a community's needs through a long-term relationship, will enable a local authority to more successfully achieve its goals. This paper will describe specific examples of relationship-based contracts in New Zealand, ranging from cities that are expanding their infrastructure to meet growth, to smaller districts that are facing static or declining populations. These examples will provide insights into what has worked well and not so well for both parties. The learnings that will be explored will be around the need to define roles, integrate the client's key personnel, the importance of culture and commitment, and the sharing of common goals to achieve mutual success and how this can consistently deliver better outcomes to the community.

A risk worth takingPresenter & author: John Kelly – Fulton Hogan

In November 2014 Fulton Hogan welcomed dozens of children into a working crusher site to play with trucks, loaders and diggers. Why?

To get staff to view the risks of their daily activities through different eyes; To show that a strong safety culture doesn't stop managed risks being taken; and To engage with the community and increase their awareness of the dangers of worksites.

Health & Safety is about more than systems, process and forms. It's about making sure everyone goes home safe and well every day. This innovative Safety Day made our staff look at health and safety in a different way. We had to risk assess from a child's perspective and adapt to the challenge of what a 6 year old might do when in charge of a mini digger. It would have been easy to say the idea was too risky and walk away. It was much harder to say it was risky, but the risk could be managed safely. By taking this latter view, our staff took ownership of the risk, came up with innovative ways of managing it, and our relationship with the community flourished. And it was all done safely. Collaboration the MPA wayPresenter: Ed Breese – Memorial Park AllianceCo-author: Steve Croft – Memorial Park Alliance

Situation: One contract, four clients


Memorial Park Alliance was formed to complete Arras Tunnel for the NZ Transport Agency. The related Pukeahu National War Memorial Park was brought into the Alliance by the Ministry for Culture and Heritage. The Alliance ability to meet tight deadlines led to the Victoria Street Transformation for Wellington City Council and Waitangi Wharf Upgrade for the Department of Internal Affairs. Response: Memorial Park Alliance has developed alliancing as collaboration based on strong partnerships and co-location, allowing daily, well-informed, joint decision-making. This supersedes the traditional client-supplier relationship and enables issues to be quickly resolved and quality to be a shared focus. Key learnings:

Dedicated teams are established with matrix managers appointed to work across all disciplines and client interest groups.

Team performance is directly related to team communication. Big tasks are broken into simple, easily communicated chunks so everyone is well-informed.

A two-pronged approach is adopted of firstly establishing collaborative behaviours and team spirit and following through with processes for consistently reinforcing these behaviours.

A clear commitment is maintained to having a strong client presence in the team.

Results: The park and underpass were each completed one month early; a major street upgrade potentially taking three years was completed in 10 months; resource consents for a major coastal reclamation were obtained in record time.

Life after alliancing – the best of collaboration and the best of competitionPresenters & authors: David Papps - Beca & Charlie Littlefair - South East Water

South East Water (SEW) sought a price-competitive project delivery model that retained the best aspects of alliancing - collaboration of owner/designer/constructor, delivery reliability, quality, operability, safety, and flexibility - but that achieved ongoing price competition in an environment of high scrutiny of capital expenditure. The 5 year $220 million Pipes and Structures program is the largest and most optimised of SEW's new procurement model introduced in 2013, following 8 years of Alliancing. The program design and constructs water, sewer and recycled water pipelines, pumping stations, storages and upgrade works at treatment plants for South East Water, Melbourne. SEW developed an innovative delivery mechanism, selecting a very limited panel of consortia to compete for the individual projects in the program. This included a risk allocation framework whereby risk is priced and allocated to the party best placed to manage in a collaborative but competitive environment. The genius is in the "AND". This paper will describe the benefits from the first two years of the program including:

outcomes achieved through the risk allocation model cost efficiencies / budget outcomes achieved KPIs and performance improvement through feedback and collaboration the capabilities and culture required to deliver under this model

FRA and MWH - a collaborative approach to asset renewalsPresenter & author: Beth Parkin – MWH Global

Fiji is facing comparable problems to many areas of New Zealand; an increasing demand for services combined with an aging infrastructure that requires significant capital investment. The Fiji Roads Authority (FRA) are undertaking upgrades of the main arterial roads in Suva and Nadi, Fiji. These are also the main arterial corridors for water and wastewater infrastructure, as well as power and telecommunications.FRA and MWH, the designer, adopted a collaborative approach, with utility operators invited to undertake upgrade and renewal works as part of the roading upgrades. IPWEA NZ 2016 Abstracts, via stream. /26

Parts of the works are already under construction with the majority expected to be completed within the next two years.

Several benefits are being realised during these works including renewal and upgrade of infrastructure at a reduced cost, co-ordination of utility corridors and the enhanced working relationships between FRA and utility operators. Conversely, there are many challenges also being encountered, including the coordination and communication between multiple stakeholders and the scale of the project (in size and cost) in Fiji. This paper demonstrates the benefits realised when a collaborative effort by utility operators is adopted and also identifies challenges that are likely to be encountered when undertaking a joint approach to renewal works.

Building a wastewater treatment plant – a win for everyone!Presenter & author: Jayne Perrin - BecaCo-authors: Ricki Freemantle, Johan Ehlers & Garry MacdonaldTypically a local authority identifies the need for a project - engages consultants to design, procure and manage construction before handing over a newly-commissioned asset. Not in the Hawkes Bay. Napier City Council took an alternative and innovative approach applying preliminary design for a plant upgrade by CH2M Beca and executing detailed design, procurement, delivery, commissioning and project management in-house. The strong prior relationship between consultant and client readily adapted to an unorthodox method of delivering a complex project. CH2M Beca exchanged the normal professional services role for a critical technical supporting role. NCC stepped up by backing themselves to accomplish the project, absorbing risk and ultimately saving money for the community. To further complicate the situation, the supply and construction phases were split into myriad contracts, using different contract types and spanning the full breadth of Council's procurement policy. The outcome was a complex project delivered on time, under budget and to a high quality, including added extras. Benefits not immediately foreseen at the outset were substantial cost savings for the rate-paying community, valuable experience gained by Council staff, as well as community investment by employing a mix of local and national contractors. Overall, a win for everyone.

The connected bus shelter – smart collaboration for a complex problemPresenter & author: Murray Robertson – Downer

The demand on Australasia’s public transport services is escalating. Growing urban congestion, rising vehicle running costs and proactive infrastructure investment has seen public transport users re-think how they move around main centres and how they better access civic services. People require connectivity and as the wave of urbanisation continues a connected liveable city is no longer an aspiration but an expectation. Recognising the opportunity to support local government with developing smart city initiatives Downer led a technology consortium to build a prototype connected bus shelter. Formed through the ng Connect industry eco-system the companies of Nokia, Solta, Metshelter, Schneider-Electric, Samsung, Chorus and Downer joined forces to develop the 'Smart Shelter' end-to-end solution. More than just a connected bus stop the Smart Shelter is a smart city hub. It offers immense potential for the local authority to present real-time interactive touch displays to their public transport users while also creating potential revenue opportunities through fibre-connected real-estate. Projects like the smart shelter test our capability to address the wicked problems of smart city implementation.

Igniting innovation through active risk managementPresenter & author: Nathanael Sterling - Beca

Is your risk management system a black box, primarily satisfying compliance? Or a driver of innovation and intrinsic part of decision making. Risk management is often perceived as compliance, justification for establishing budget contingencies should things go wrong, or proving that the risk had been identified. What is often


missed is the 'gold' hidden within the stored information on how to create safer environments, deliver on project goals and objectives.Compliance driven risk management process often struggles with staff engagement, undermines creativity and to the extreme it creates barriers to the work activities. What if risk management was used to drive innovation, identify the opportunities to achieving objectives, improve safety outcomes, increase certainty and bring transparency to underlying assumptions?An open and collaborative approach to risk management can tap into the huge database of answers, ideas and solutions held within staff, project stakeholders and the risk management process. Key Points:

Risk management processes and information systems hold a lot of great information to achieve better, safer outcomes

Managing risk is about open dialogue Bring focus to achieving objectives not barriers to success
