2022 CONCRETE NZ CONFERENCE & AWARDS WINNERS CONGRATULATED

NET ZERO CARBON ROADMAP & SUSTAINABILITY REPORT UNDER DEVELOPMENT

VOLUME 62 ISSUE 2 concrete

UPFRONT concrete MAGAZINE

THE ROADMAP’S CONCRETE PAVEMENT

The New Zealand concrete industry is on a journey to decarbonise, and has set emissions reduction targets of 30 percent by 2030, and net zero carbon by 2050.

To help industry remain focussed on these targets Concrete NZ is working with thinkstep to develop an Industry Roadmap for Net Zero Carbon 2050 (see pages 28-31 for details).

Set for release in early 2023 the Roadmap will allocate a percentage weighting to different levers that industry will use to decarbonise, such as increased substitution of coal to fuel Golden Bay’s Portland kiln, further uptake of supplementary cementitious materials and improved efficiency in concrete design and construction.

Another key component of Concrete NZ’s future work programme, one aligned to Aotearoa New Zealand’s post-2020 commitment to reduce greenhouse gas emissions under the Paris Agreement, is continued advocacy for concrete roads - the pavement to the Roadmap so to speak.

The benefits of concrete roads are many, and cover environmental, economic and safety considerations. If New Zealand is serious about its net zero carbon ambitions, then the case for concrete roads is now more compelling than ever.

To this end Concrete NZ recently supported the Future Roads conference which provided the roading sector with a forum for strategy, discussion and execution.

In addition to taking an exhibition space, we arranged for Jamie Egan of Acciona in Australia to present an overseas perspective on the design and construction of concrete pavements, and how they can potentially be implemented in New Zealand.

Interest from conference delegates was encouraging, adding impetus to Concrete NZ’s advocacy endeavours with Hon. Michael Wood, Minister of Transport, as well as Waka Kotahi New Zealand Transport Agency moving forward.

CONFERENCE 2022 DELIVERS

IT WAS WITH A SENSE OF RELIEF AND EXCITEMENT THAT CONCRETE NZ’S 2022 CONFERENCE RECENTLY TOOK PLACE AT THE ENERGY EVENTS CENTRE IN ROTORUA AFTER A THREE-YEAR PANDEMIC ENFORCED ABSENCE.

Over 400 delegates from Aotearoa New Zealand’s concrete industry and wider construction sector, supported by a strong contingent of exhibitors, gathered to knowledge share, network and enjoy a range of social activities.

Chair of the Conference Organising Committee, Professor Alessandro Palermo, got proceedings underway by welcoming delegates and outlining how the broad theme of ‘Sustainability’ would be reflected throughout the event.

Keynote speaker Professor Santiago Pujol, from the University of Canterbury, led the technical

programme by exploring how the concrete of the future must be reused & reusable, robust and combined with other materials.

The 2022 Conference would not have been possible without the assistance of dedicated patrons, sponsors and industry supporters, who embraced the event with enthusiasm.

Concrete NZ hopes everyone had the chance to catch up with friends old and new, and spend time discussing key developments in concrete materials, design, construction and research.

HONORARY LIFE MEMBERSHIP - BOB OFFICER

Long-time concrete industry advocate Bob Officer was recognised as Concrete NZ’s third Honorary Life Member at the association’s 2022 Conference in Rotorua.

First granted in 2021, Honorary Life Membership recognises individuals for their eminent contribution to the concrete industry. It is the top tier of Concrete NZ membership; the standard to achieve it is set exceedingly high.

To be considered for Honorary Life Membership, a nominee must demonstrate attributes including eminence, sustained leadership and industry mana.

Bob was chosen for the honour due in no small part to the huge regard with which he is held across industry for his broad experience, technical expertise, and political acumen.

A supremely effective communicator, capable of connecting with the complete range of practitioners and specifiers across the wider

ROB GREEN

construction sector, Bob has always been a natural figurehead, willing to lead industry on matters of common interest while at the same time meeting his own professional commitments with Palmers Concrete and then Allied Concrete.

Bob’s drive to advance the entire concrete industry is nowhere more evident than in his involvement with the New Zealand Ready Mixed Concrete Association (NZRMCA) as a Council member, and on the Board of the Cement & Concrete Association of New Zealand (CCANZ). More recently, his strategic and governance acumen played a pivotal role in realising the vision to consolidate five concrete industry associations into Concrete NZ.

In short, Bob’s passion for the concrete industry and his dedication / loyalty to both his employer and associations has endured for close to 30-years and make him a worthy recipient.

Rob Green, recently retired from Higgins Concrete, received Concrete NZ Honorary Life Membership in 2021 along with David Barnard. With the 2022 conference proceeding as planned it was wonderful to have the opportunity to celebrate Rob’s career achievements with the Concrete NZ’s collective membership.

PLANT SUPERVISOR FIRST WOMAN TO WIN CONCRETE INDUSTRY APPRENTICE OF THE YEAR

Megan Blance of Allied Concrete became the first woman to take home the Concrete Industry Apprentice of the Year award at Concrete NZ’s annual conference held at the Energy Events Centre in Rotorua.

This year marks the sixth Concrete Industry Apprentice of the Year award, which was open to those enrolled in, or who have recently completed, one of the BCITO’s concrete National and New Zealand Certificates.

The standard of finalists was exceptional, covering those who work and train in precast concrete, placing and finishing, concrete production, and concrete construction.

The judges noted that Megan, plant supervisor for Allied Concrete in Blenheim, embodied a range of attributes which saw her rise above the other highcalibre entrants to be recognised as the Apprentice of the Year.

Helping celebrate Megan’s achievement at the Awards function were her Allied Concrete colleagues, friends and whānau, as well as the Concrete NZ and BCITO teams, and representatives from across the concrete industry and construction sector.

In congratulating Megan, Concrete NZ chief executive Rob Gaimster remarked how this year’s entrants were not only an outstanding group of

individuals, but also the most diverse since the award was launched in 2016, demonstrating the concrete industry’s development over recent years.

“Megan’s perseverance is clear, as is her commitment to building strong relationships with customers and fostering high-morale amongst her team,” says Rob.

Andy Parker, Allied Concrete’s Nelson, West Coast & Marlborough area manager, can’t speak highly enough of Megan’s courage and dedication when she chose to relocate to Blenheim and become Plant Supervisor.

“Megan puts her staff first and is well respected by customers,” says Andy. “Allied Concrete has a future leader in the making.”

Megan’s BCITO training advisor Mark Blom, offered similar praise when acknowledging her temperament and success.

“Megan is more than deserving of this recognition as she has a tremendous attitude, great leaderships skills, an enthusiasm for mentoring along with a tireless work ethic.”

Director Jason Hungerford, of BCITO reflects, “Megan’s achievement is even more impressive when you consider that less than three percent of construction tradespeople are women. We salute Megan’s achievement and also her leadership as a successful woman in the trades.”

NEW CONFERENCE AWARD CATEGORIES EMBRACE THE FUTURE WHILE RESPECTING THE PAST

In addition to celebrating notable individuals, the first set of Concrete NZ Conference Awards adapted existing categories and introduced new ones to recognise members’ customer service, technical expertise, diversity & inclusion, health, safety & wellbeing, as well as carbon reduction efforts.

EXTRA DISTANCE AWARD

Busck Prestressed Concrete for the America’s Cup 36 Hobson Wharf Extension, Auckland

This award is given in recognition of a producer’s involvement in a project or initiative that demands uncompromising commitment to customer satisfaction. The challenges associated with each entry, and the solutions to overcome those challenges, are evaluated to determine the award winner.

Through a combination of early engagement and mutual trust with the Wynyard Edge Alliance (WEA), Busck Prestressed Concrete was able to commence specialist mould building and liaison with Pacific Steel at an early stage to avoid delays and minimise wastage.

Busck’s relationship with North Port was key to the project’s precast elements being delivered by barge from its Marsden Point yard, located near Northport Whangarei, into the Auckland Viaduct. By using sea transport around 64,000 kilometres

of road transport were diverted, and 561 inner-city truck movements avoided.

Six barge loads transported a total of 8,800 tonnes of precast, pile casings and pile rebar cages to the Hobson Wharf worksite. A seventh load delivered a further 1,070 tonnes of wave break elements.

The judges saluted Busck’s (and their project partners) experience, capability and willingness to innovate, not to mention the ideal location of its Marsden Point yard in Whangarei, which saw the extra mile taken and delivery made ahead of schedule.

EXTRA DISTANCE AWARD - HIGHLY COMMENDED

Higgins Concrete for KiwiRail’s Pile Upgrade in the Hutt Valley

Due to access difficulties, a standard truck-based pouring solution would not suffice on this project, so Higgins Concrete developed a purpose-built, rail-mounted, concrete mixing bowl to efficiently lay foundations for 965 new steel poles along the Petone to Upper Hutt rail line north of Wellington. Built by Waikato-based Technical Welding Services, the mobile unit was designed to KiwiRail’s stringent safety standards and was transported along the tracks by a KiwiRail-supplied hi-rail trailer and a hirail tug unit.

Concrete was moved from a standard concrete truck to the mobile unit via concrete pump, while wash out was managed using a water truck that took contaminated water back the local plant’s treatment ponds.

The judges commended this innovative solution, which helped pour up to 2,000 cubic metres of concrete for the steel pole foundations over 18-months, noting that sometimes the most effective solutions appear the simplest.

TECHNICAL EXCELLENCE AWARD

Allied Concrete for Te Ara a Toa (Bridge 20) on Transmission Gully, Wellington

This award is given in recognition of a producer’s involvement in a project or initiative which calls for innovative solutions to meet a challenging architectural vision or engineering requirement.

At 27 kilometres in length, Transmission Gully is a key part of the Wellington Northern Corridor. Twenty-five new structures have been built along the route, the largest of which, Te Ara a Toa (Bridge 20) over Cannons Creek, stretches 230 metres in length and sits 60 metres above the valley floor. The technical challenges associated with designing and building a long, high, curving bridge that is aesthetically pleasing yet able to withstand a 1 in 2500-year seismic event required an innovative approach, particularly in terms of concrete mix design.

Due to the size of the foundation blocks and the bridge piers, pier heads and deck the thermal characteristics of specialist low heat of hydration concrete mixes had to be thoroughly investigated during the design stage.

The judges were extremely impressed with Allied Concrete’s exhaustive commitment to detail, the outcome from which is the showpiece concrete structure on one of the most significant new roads in New Zealand.

HEALTH, SAFETY & WELLBEING ACHIEVEMENT AWARD

Firth Industries and Higgins Concrete for their Groov by Mentemia Partnership

This new award category acknowledges organisations and individuals that have demonstrated innovation and leadership in helping to improve health, safety and wellbeing in the concrete industry.

Higgins Concrete and Firth Industries have prioritised a wellbeing programme for all staff as an extension of their core Health and Safety policies. Prompted by a growing understanding that the wellbeing of people is a significant health & safety issue, accentuated by pandemic disruption. Extensive research led both companies to enter a partnership with Mentemia (now “Groov by Mentemia”), the basis of which is a workplace and community platform to enhance individual wellbeing.

Adopting a holistic approach to truly embed mental wellbeing as the default way of working, the programme consists of three stages – Launch, Build and Stick – with Mentemia’s 6 Pillar Surveys used to ensure long-term entrenchment.

A key component is the Mentemia App, which offers interactive tools that were valuable in

helping staff work virtually, manage lockdowns and return to work.

Follow-on Lead, Show and Care modules enable leaders to support themselves and their people, at work and home. This framework is complemented by regular Temperature Checks that assess the programme’s effectiveness.

The judges acknowledged the foresight of Higgins Concrete and Firth Industries in choosing to work with Mentemia, an organisation co-founded by Sir John Kirwan and Adam Clark, with clinical management by Dr Fiona Crichton. Through this type of work, health & safety has evolved to include wellbeing, and normalise mental health care across industry.

DIVERSITY & INCLUSION AWARD

Firth Industries’ “Name of the Game” Initiatives

This award acknowledges organisations and individuals that have made a genuine commitment to advancing their culture by embracing:

Diversity as the presence of difference within a given setting; and

Inclusion, which relates to individuals with different identities feeling and being valued within that setting.

The next entry is from Firth Industries which is proud of the many cultures, beliefs, and lifestyles of its over 700 staff, believing that a workplace where differences in gender, gender identity, age, race, nationality, sexual orientation and physical ability are welcomed and included.

As part of Fletcher Building, Firth Industries:

• supports equal employment opportunities,

• has zero tolerance for any form of discrimination, harassment and victimization

• cultivates a culture of inclusion; and

• empowers those that act in accordance with the Inclusion and Diversity Policy.

Example of Firth Industries’ efforts include:

• Rainbow Tick accreditation

• Participation in Fletcher’s ‘Whakatupu Māori Leadership’ programme

• Support for English as a second language staff

• enhanced parental leave allocation; and

• the Women of Firth programme

Firmly committed to diversity and inclusion, the judges congratulated Firth Industries on the huge strides they have made in meeting the needs of its staff, suppliers and customers, by making everyone feel more connected, and in turn have improved brand reputation while boosting productivity.

CARBON REDUCTION AWARD

Golden Bay for its Waste End-of-Life Tyres Project, Portland, Whangārei

Another new category in 2022, the Carbon Reduction Award acknowledges those organisations that have undertaken initiatives to reduce their carbon footprint, and in turn help the concrete industry achieve its 2030 vision and 2050 target.

Golden Bay used 25,000 tonnes of tyres to replace 27 percent of coal in cement manufacturing during the first full financial year after commissioning.

Diverting over 3 million waste tyres from landfill in the first 15 months of operation has equated to a carbon reduction of 20,000 tonnes of CO2 equivalent.

As well as carbon reduction, there is a significant decrease of waste to landfill, a lower risk of uncontrolled tyre stockpile fires, as well as a drop in international transportation emissions from the export of waste tyres.

Noting that in addition to the 27 percent substitution of coal for waste end-of-life tyres, Golden Bay also substitutes a further 20 percent with biofuel wood waste to achieve an overall alternative fuels substitution of around 50 percent, the judges applauded this visible initiative as leading the way for the concrete industry’s decarbonisation journey.

BEST PAPER AWARD RECOGNISES UNDERPINNING OF AUCKLAND’S CHIEF POST OFFICE

Niraj Ranjit & Michael Chung (Aurecon), Nick Craig & Dale Burtenshaw (Downer Soletanche Bachy JV) and Richard Gray (Freyssinet NZ) took home the Sandy Cormack Best Paper Award at the 2022 Concrete NZ Conference for Underpinning Of Auckland’s Chief Post Office Building.

The fascinating paper and presentation outlined how the construction of twin rail tunnels beneath the Category 1 heritage Chief Post Office (CPO) building in one of New Zealand’s largest railway stations presented major challenges for CRL delivery. These challenges led to several New Zealand first innovations, including the underpinning of the CPO building.

The Best Paper Award was established in 1998 in the memory of H.W. (Sandy) Cormack, and recognises topics relevant to the development of the concrete industry in New Zealand.

It is judged against the written paper’s structure, clarity and completeness, the presenter’s ability

to connect with and hold the audience, as well as the paper’s overall significance and relevance in the development of concrete knowledge.

Mike Botherway of Higgins Concrete was recognised with a Highly Commended Award for his paper It’s Okay Not to Be Okay – Your Daily Mental Health Journey.

Mike Botherway of Higgins Concrete was recognised with a Highly Commended Award.

H.W. (SANDY) CORMACK

Perhaps no other individual is more synonymous with the concrete industry in New Zealand than Sandy Cormack. Wellington born, Sandy was an engineer who became chief executive of Certified Concrete Ltd from its establishment in 1938 until retiring in 1971.

Sandy had a principal role in setting-up the NZ Portland Cement Association in 1948, and served on the board until 1978. Through his work in introducing quality control to concrete production he also served on many Standards committees.

Sandy was instrumental in establishing the NZ Ready Mixed Concrete Association, and its plant classification scheme. He was involved with the establishment of the Prestressed Concrete Institute (later to become the Concrete Society), and was its first President.

However, many believe Sandy’s greatest achievement was his influence almost 75 years ago in the creation of the first two ready mixed concrete plants in New Zealand at Grant Road in Wellington and Madeira Lane in Auckland’s Grafton. These plants launched New Zealand into high-tech concrete, and it was from there that the formidable drive and talents of Sandy Cormack were to provide huge leadership and service.

CONCRETE INDUSTRY AWARDS WILL SET NEW BENCHMARK IN EXCELLENCE

CONCRETE NZ IS THRILLED TO ANNOUNCE THAT ENTRIES ARE OPEN FOR THE FIRST-EVER CONCRETE INDUSTRY AWARDS, WHICH WILL BE PRESENTED AT THE ROYAL NEW ZEALAND YACHT SQUADRON IN MARCH 2023.

The new industry awards are set to become the benchmark for excellence in all aspects of concrete design, construction, rehabilitation, research and innovation.

Concrete NZ chief executive, Rob Gaimster, is excited to open entries to the wider New Zealand building and construction sector, and expects a high level of interest based on concrete’s status as a critical material across residential, commercial and infrastructure works.

“These new awards are very much outwards facing and inclusive, focussing on projects and initiatives that involve all building and construction sector businesses, including Concrete NZ members, as well as their clients, academic institutions and government agencies,” says Rob.

“The awards also recognise the individual leaders and team members who are designing, constructing, preserving and repurposing New Zealand’s future, low carbon, built environment.

“A special thank you to our Patron, Nauhria Group, along with all the Award Category sponsors.”

Along with the Nauhria Premier Concrete Award, the following categories will be acknowledged at the March 2023 event:

GETTING AHEAD OF THE CURVE ON DECARBONISATION AND SUSTAINABILITY

Bernie Napp – Concrete NZ, Sustainability & Policy Director

“GREEN” CONCRETE IS A GLOBAL PHENOMENON AND IS MAKING HEADWAY IN AOTEAROA NEW ZEALAND. CONCRETE NZ IS ON A MISSION TO MAKE THIS STORY COMPELLING FOR ALL WHO USE AND REGULATE CONCRETE.

In 2021 the Global Cement and Concrete Association (GCCA) produced a decarbonisation roadmap, titled Our Concrete Future. This document sets out seven levers for moving the global cement and concrete sector to net zero carbon by 2050.

Six years earlier the United Nations Organisation (UN) had published 17 Sustainable Development Goals (SDGs) for nation states to create a better

world. The SDGs include health and wellbeing, clean water, renewable and affordable energy, jobs and economic growth, industry and infrastructure, sustainable cities, responsible consumption, and climate action. All of which are relevant to concrete.

The SDGs and the GCCA work are a call to action for the New Zealand cement and concrete industry to accelerate advocacy and communications efforts

around climate change. Conveying concrete’s sustainability credentials and its decarbonisation journey is a challenge fully embraced, however the task will be difficult as some inaccurate perceptions are long-standing.

For instance, the Ministry of Business, Innovation and Employment’s (MBIE) Building for Climate Change programme expressed a clear preference for timber over concrete in building and construction, which required Concrete NZ to balance in its submission.

Similarly, the Ministry for the Environment’s (MfE) draft National Adaptation Plan for climate change contained no reference to concrete in combatting sea level rise, preferring the creation of wetlands and “managed retreat”. Concrete NZ’s advocacy saw the final Plan include “sea walls” as a climate change adaptation option.

At the recent NZ Bridge Summit in Wellington, Waka Kotahi NZ Transport Agency presented on building highway bridges out of timber, and asked if concrete would “lead to an over-reliance and bias in bridge construction”. This stands in contrast with KiwiRail’s replacing wooden railway bridges with concrete and steel structures.

To better influence the sustainability and climate change debate, Concrete NZ has taken an approach known as ESG – “environmental, social and corporate governance”.

WHAT IS ESG?

ESG concerns the material impacts, positive and negative, of a business or industry on people and the environment, and how the external world impacts on the business or industry. Organisations use sustainability reporting to disclose their impacts, and to guide improvements to their environmental (including carbon) and social footprint over time.

The ESG concept was coined in 2004, and since then its use has grown exponentially, particularly from 2018. It differs from earlier, voluntary approaches to sustainability, e.g., “triple bottom line” and “corporate social responsibility”. Rather, it is a response to external threats, risks and opportunities posed to businesses. These include government policymakers and regulators, financial markets, customers, communities and indigenous people, environmental NGOs, and people looking for rewarding careers.

ESG allows entities to deal with the inevitable tradeoffs between achieving profit and protecting the environment – methodically, transparently and effectively.

In the case of concrete, the industry has a positive and verifiable story to tell, one of rapidly decarbonising, and reducing its environmental footprint.

This supports Concrete NZ in promoting a collaborative, informed approach to debate, to create a positive vision for concrete. To that end, we are producing a decarbonisation Roadmap, and a Sustainability Report.

DECARBONISATION ROADMAP

In 2022 Concrete NZ commissioned Australasian consultancy thinkstep to develop a decarbonisation Roadmap, due for completion in early 2023. Concrete NZ is the project manager and coordinator of the project, being funded by ourselves, as well as by the MBIE and BRANZ.

Inspiration for the Roadmap comes from the progress industry has made to date. Between 2005 and 2018 it reduced CO2 emissions by 15 percent, against a 13 percent volumetric increase in ready-mixed concrete production over that time. Thinkstep verified the data in early 2020, and is currently updating the figures.

This success led Concrete NZ, in consultation with members, to set emissions reduction targets of 30 percent by 2030, and net zero carbon by 2050.

The GCCA report identified several levers for CO2 emissions reductions. Thinkstep is evaluating these for application in the New Zealand context. At this stage, lower-emissions kiln fuels, reducing clinker factor in cement, and partially replacing cement with supplementary cementitious materials are gaining traction. We envisage improvements also in concrete design and construction, and transport emissions.

SUSTAINABILITY REPORT

Concrete NZ is also leading the development of a pan-industry Sustainability Report, based on a materiality assessment of industry impacts on people and the environment. This was done in April 2021, consistent with an international standard, the Global Reporting Initiative.

The material topics Concrete NZ chose for sustainability reporting are: energy and emissions; waste and circular economy; freshwater; benefits to the built environment; health and safety; and socio-economic benefits.

Data collection is underway for the year to 30 June 2022, with many returns already received, and report completion expected in early 2023. Thinkstep is providing strategic advice, peer review, editing and design.

WHERE TO NEXT?

ESG is increasingly the must-do approach for businesses in a world of tightening regulation, and rising societal expectations of the private sector, including of the cement and concrete industry.

32 concrete VOLUME 62 ISSUE 2

Many companies in our industry are already pursuing decarbonisation, obtaining Environmental Product Declarations (EPD), or are preparing their own sustainability reports.

Concrete NZ is playing our part, via the decarbonisation Roadmap and the Sustainability Report. We are inserting cement and concrete firmly into the sustainability conversation in New Zealand. Examples include implementation of the MfE’s Emissions Reduction Plan, MBIE’s Building for Climate Change programme, and Waka Kotahi work on updating concrete specifications for its Highway Structure Construction Guide. This last workstream

is important to building Concrete NZ’s case for concrete roads and bridges.

Good information, communications, and engagement with government and other stakeholders are at the forefront of our work to enhance recognition of the cement and concrete industry’s fast-reducing carbon and environmental footprint, among designers, architects, builders, customers, regulators and policymakers.

Concrete has a bright future in a modern New Zealand as the construction material of choice for resilient buildings and infrastructure.

ENGINEERS LAUNCH NEW BUILDING SYSTEM TO PROTECT HOUSES IN A QUAKE

CANTERBURY ENGINEERS ARE MOVING FORWARD WITH PLANS TO MANUFACTURE A NEW BASE ISOLATION SYSTEM THAT WILL MAKE KIWI HOUSES SAFER IN AN EARTHQUAKE.

A prototype of the system was tested last year by a University of Canterbury team led by Civil and Natural Resources Engineering Professor Tim Sullivan and postdoctoral fellow Tom Francis.

It showed very promising results and with the encouragement of University of Canterbury Research and Innovation staff, the project team has now won funding from KiwiNet’s Emerging Innovator Programme.

The programme supports scientists to develop their innovations through a business-lens and take them into the world where they can make a difference. KiwiNet has also provided $40,000 in Tier 1 PreSeed Funding.

Dr Francis is using the Emerging Innovator funding to work on commercialisation of the base

isolation system over the next six months, as well as designing a second prototype.

He says next year they plan to set up a company with the goal of supplying the devices to housing developers and overseeing their construction. He would take up a role as managing director of the new company.

“I’m quite driven to do this commercialisation work and starting a company would be really rewarding. It’s not something that I was expecting at the start of my research, but I’ve discovered that it’s my interest as time has gone on.”

The Emerging Innovator Programme also provides him with a mentor, experienced engineer John Cunningham, Executive Director at Ignition Partner Ltd, who is helping him work on the commercialisation process.

University of Canterbury postdoctoral fellow Tom Francis (right) and Civil and Natural Resources Engineering Professor Tim Sullivan (left) are keen to start manufacturing a base isolation system for residential houses. (pictured with UC Structural Engineering Laboratory Manager John Maley).

“I’m developing another prototype - we’re calling it a phase two system - which will have even more cost-effective construction than our original design,” Dr Francis says.

“We’re planning on talking to housing developers because we think the system will be a good selling point for new houses, making them safer for people to live in.”

He is excited about bringing the new system to market. “I was optimistic about completing a PhD that would have potential real-world benefits and after working with future stakeholders in this system, I feel positive this product will be able to be implemented.

“The testing we did of the original system using a shake table in the Structural Engineering Laboratory went even better than we expected and showed that the device we’ve created does help prevent damage to residential houses in a large earthquake.”

The base isolation system is designed to help homeowners avoid costly repairs and stressful insurance claims in the event of a major earthquake.

Testing showed that it limits building deformation, preventing damage to walls and cladding, and keeps floor and roof accelerations low which helps to protect building contents.

Last year, a mock-up room with gib lined walls was positioned on top of the newly-developed steel base isolation units, with the University of Canterbury’s shake table underneath.

The table – one of the largest in New Zealand – recreated ground movements recorded at various locations during the damaging Canterbury earthquakes as well as other strong earthquakes and a simulated Alpine Fault quake.

Results showed the base isolation units were effective and would have withstood the 20102011 Canterbury quakes and 2016 Kaikoura earthquakes (7.1 and 7.8 magnitude respectively), as well as an Alpine Fault scenario, without the room needing any repairs.

Professor Sullivan and Dr Francis’ goal is to keep the seismic system as low-cost as possible so it can be widely adopted by homeowners around the country, making their houses significantly safer.

“We think what we’ve come up with will prevent damage, and it doesn’t cost an arm and a leg.

It also promises to reduce the disruption caused by a major quake, helping communities recover more quickly,” Professor Sullivan says.

Base isolation systems, developed to prevent or minimise damage during an earthquake, are primarily used in commercial or civic buildings in New Zealand because they are usually expensive and require specialised engineering.

The aim with the new residential system is to keep the total cost of manufacturing and installing the base isolation system to less than 5% of the total construction cost for a house.

Professor Sullivan says houses in New Zealand currently perform well in terms of saving people’s lives, but there is room for improvement in terms of preventing damage to the structure and its contents.

“Research has shown that the most upsetting thing for a lot of people wasn’t the earthquake itself, it was dealing with insurance claims, the potential loss of value for their houses, and the damage to their belongings. If we can avoid that, then I think there will be psychosocial benefits.”

HOW DOES THE NEW BASE ISOLATION SYSTEM WORK?

The main hurdle to overcome during the design stage for the innovative system was balancing the need for a house to be stable in high winds but also able to flex and absorb shock from an earthquake.

The system is created by installing several steel base isolation units under the concrete foundation of a house, which work in a similar way to traditional piles.

The concrete slab includes steel plates that float and slide on small round discs in the units, called ‘pucks’, allowing the house to move around in a quake and absorb the displacements and accelerations imposed by ground shaking.

The system is compatible with common building techniques for New Zealand houses and can be used under steel and timberframed buildings or other typical structures.

It’s designed to be sustainable and easy to repair after an earthquake.

LARGEST QUAKE SIMULATOR IN SOUTHERN HEMISPHERE HEADING FOR CANTERBURY

A NEW UNIVERSITY OF CANTERBURY (UC) EARTHQUAKE SIMULATOR WILL BE THE FIRST LARGE-SCALE RECONFIGURABLE ‘SHAKE TABLE’ IN NEW ZEALAND AND THE BIGGEST IN THE SOUTHERN HEMISPHERE.

The UC Structural Engineering Laboratory (SEL) will be home to the first facility for large-scale dynamic testing of structural and non-structural components. The modular system can be rapidly reconfigured for various commercial and research purposes, including shaking the base of test buildings, and material testing.

UC Civil Engineering Professor Santiago Pujol says the facility will help researchers explore, learn and teach new ideas on how to build better buildings.

“The challenge with civil engineering is you can’t test-drive a building and, with limitations of computer simulation, there can be uncertainty about whether the building will behave the way we expect,” says Professor Pujol.

“This new modular system will allow us to build representations of both old and new buildings to test our ideas on how they react to earthquake demand.”

The simulator includes a battery of powerful hydraulic actuators that simulate the motion caused by earthquakes on separate foundations or the entire base of a test structure. The simulator can also be used to reproduce the relative motions between two floor slabs in a high-rise structure. In such a test, the walls and building contents move and distort as they conform to the displacements that buildings reach during earthquakes, he says.

The new earthquake simulator increases the impact of research at UC while tackling the challenge of providing cities with more resilient and sustainable buildings.

“This type of investment in new equipment is invaluable,” says Professor Pujol. “It can be configured for a range of research applications from simulating high-intensity earthquake demands, testing materials at high strain rates for aerospace applications, to routine commercial testing for the construction industry and student-led projects focusing on the dynamic response of structures.”

UC has had a conventional ‘shake table’ for decades, which will continue to be used for smallscale testing. It was recently used to test the prototype of a new base-isolation system making Kiwi houses safer in an earthquake.

The new large-scale system will greatly expand the range of dynamic tests and applications at UC.

Professor Pujol says with the Ministry of Business, Innovation and Employment and Engineering NZ preparing updates to design guidelines for buildings, industry will be looking for methods to gauge the performance of both new and old seismic technologies.

INNOVATION IN TBM TRAFFIC TUNNELS BY BY

Tunnel Boring Machine (TBM) constructed tunnels are widespread, and can deliver significant environmental and cost benefits. However, as noted in the examples of TBM traffic tunnels presented in this book, there are still important challenges associated with them, linked in particular to structural safety in the event of earthquakes, as well as cost and safety issues during operation.

To face these challenges, this book presents three innovative concepts in the field of construction of TBM rail and road tunnels: the TISB concept that improves the structural safety of those built on soft soil in seismic areas, and the TMG and TMF concepts, for rail and road tunnels, respectively, that allow for significant reduction of their cost and the improvement of safety during operation. Examples of the application of these new concepts in the conceptual design of specific tunnel cases are presented and compared with solutions based on common approaches, demonstrating the additional benefits of these concepts. The book also draws attention to other innovations in TBM tunnelling that may improve the construction of tunnels in the future, especially when using the concepts mentioned above.

Innovation in TBM Traffic Tunnels is aimed at professionals involved in the planning, design, and construction of tunnels for transport infrastructure, including authorities, consultants and construction companies, worldwide.
