We are proud to have an 11-strong team presenting at this year's Institute of Public Works Engineering Australasia conference (IPWEA NZ 2016), which will be held from 22-25 June. Beca and CH2M Beca are bronze sponsors, sponsoring the ‘Transport’ and ‘Water’ streams. Our papers focus around the conference theme: 'Adapt, Innovate, Flourish' - innovative, 'out of the box' thinking to look at new ways to manage, maintain and develop infrastructure.
Below are summaries of the papers:
'Igniting innovation through active risk management': Nathanael Sterling (Associate - Project Management)
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. 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?

'Monitoring of the River Recharge with Groundwater scheme': Martyn Cole (Kapiti Coast District Council) & Tracy Clode (Associate - Project Management). Beca co-authors: Kirsten Fraser (Associate - Environmental Engineering), Michael Goff (Associate - Hydrogeology) & Nathan Baker (Manager - Environments)
Kapiti Coast District Council's award-winning River Recharge with Groundwater scheme has been monitored through two summers focusing on four ecosystems: Waikanae borefield, seven small coastal streams, 13 wetlands, and Waikanae River. This presentation described describes the setup of that network and system and the changes made to the consents to recognise the practicalities both on-the-ground and in the monitoring framework. It also discusses how a collaborative and pragmatic approach to the monitoring, and adaptive management can work in practice.

'Rapid, integrated subsurface ground modeling at Puketutu Island': Mike Thorley (Associate - Hydrogeology)
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; the presentation discusses this project.

'The nitty gritty of making grit removal resilient at CWTP': Raelene Stewart (Senior Associate - Project Management). Co-authors: Greg Offer (Project Director - Water) & Lee Liaw (Christchurch City Council)
The 2010/11 Christchurch earthquakes 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 were frequently overwhelmed by the volume of grit coming into the plant. This presentation describes how simple, 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.

'Life after alliancing - the best of collaboration and the best of competition' David Papps (Technical Fellow - Water) & Charlie Littlefair (South East Water)
South East Water (SEW) sought a price-competitive project delivery model, which retained the best aspects of alliancing and also achieved on-going price competition in an environment with high scrutiny of capital expenditure. The five year, $220 million Pipes and Structures program is the largest and most optimised of SEW's new procurement model, which was introduced in 2013 following eight years of alliancing. This paper describes the benefits from the first two years of the program including outcomes, efficiencies, budget, and also the KPIs, feedback, culture and collaboration required to deliver under this model.

'Prizes and pitfalls of relationship based contracts': Kristina Hermens (Senior Associate – Project Management) & Wally Potts (Tauranga City Council. Co-authors: Gijs Hovens (Christchurch City Council) & Mark Christison (Business Director - Operations & Maintenance Markets)
More local authorities across New Zealand are working in collaboration with professional services providers by entering into relationship-based contracts to help them deliver more efficient, effective infrastructure assets and services to their communities. This paper describes 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.

'A seismic shift in design - Embedding safety and value into resilient post-earthquake designs for 3-waters infrastructure': Ian Macbeth (Manager - Water). Co-authors: Iain Partington (Project Director - Water), Gavin Hutchison (Associate Engineer - Water) & John Moore (Christchurch City Council)
The post-earthquake infrastructure rebuild in Christchurch has provided an opportunity to fully integrate safety in design and value engineering into designs. With seismic resilience fundamental to these designs, there is also a need to balance financial constraints imposed by insurance payments with a focus on incorporating whole-of-life safety considerations. These apparently conflicting drivers have emboldened designers to go beyond conventional conservative designs to come up with smart, cost-effective solutions. This paper summarises some of these innovative solutions using delivered examples from the Christchurch rebuild, as well as one built elsewhere.

'Safety in design in the water industry': Kirsty Johns (Manager - Water)
In Australia, the concept of 'Safety in Design' has been around for a few years, 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 highlights some key lessons.

'Building a wastewater treatment plant - a win for everyone!': Jayne Perrin (Senior Project Manager - Water). Co-authors: Garry Macdonald (Business Director - Water), Ricki Freemantle (Napier City Council) & Johan Ehlers (Infir)
Typically a local authority identifies the need for a project then engages consultants to design, procure and manage construction before handing over a newly-commissioned asset. Not in the Hawkes Bay, however. 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. This presentation discusses the outcome of this complex project, delivered on time, under budget and to a high quality, including added extras.

'Reporting ONRC Measures: Some Tips, Tricks and Guidance': Mike Tapper (Technical Director - Transportation)
The Roading Efficiency Group and the NZ Transport Agency have released the One Network Road Classification 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 submission. In conjunction with the measures is a shift from 'funding' to 'investment', a focus on customer outcomes and building business cases. This paper provides some guidance around the context of the measures to enable Road Controlling Authorities to understand the background, philosophy and intent behind the measures.

'Successful approaches to managed aquifer recharge - goal setting, planning, design and execution': Michael Goff (Associat - Hydrogeology)
Managed Aquifer Recharge (MAR) has been described as the intentional increase of recharge to groundwater aquifers for storage, supply and/or environmental benefit. 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. This presentation aims to communicate successful approaches to planning and executing MAR projects, including the benefits and limitations.
