Funding the Needs of an Ageing Rural and Regional Population Dear Readers, One of my favourite things about being in this line of work is that it presents me with an ideal opportunity to travel extensively throughout Australia. Perhaps most importantly, rather than simply focusing on our capital cities, I also get the chance to regularly travel throughout much of rural and regional Australia - visiting municipalities both large and small. While the area defined as ‘Rural and Regional Australia’ is clearly as diverse as Australia is large - with individual towns, cities and municipalities each facing their own particular circumstances and challenges - there does appear to be one major issue now facing all rural and regional councils, namely, the additional strain being placed on Local Government services and facilities as a result of an ageing population. Whilst the issues relating to an ageing population are clearly also a major concern for metropolitan councils (and one which I in no way intend to understate or trivialise) I believe that there are a number of additional factors that make this an even larger problem for rural and regional councils – a fact which has been confirmed by both Census data and numerous other studies and reports. Put simply, the ever-increasing average population age gap between the city and 2

Construction Engineering Australia • June/July 2018

the country places a massive financial burden on rural and regional councils as they struggle to provide additional services and facilities. In recent years, rural and regional areas have experienced a steep increase in the percentage of residents aged 55 or over. Together with the fact that most Australians are now living longer, in rural areas it is common practice for those who have spent their life on the land to move ‘off the farm’ and into a nearby town when they retire - generally for reasons of better access to services. In addition, ever-increasing numbers of older people and/or retirees are moving out of the major capitals and into rural and regional cities. While many of these people are simply looking for a change in their lifestyle, there are also those who are taking advantage of the massive growth in property values that has occurred in the major capitals over recent years - selling up and trading up for more affordable real estate in regional areas. Not surprisingly, the increasing ‘age imbalance’ between the city and the country is a serious concern and is already shaping up as a major threat to many councils throughout rural and regional Australia. Councils are not only being faced with a sharp increase in demand for human services, they’re also under

constantly growing pressure to provide more suitable age-related infrastructure, such as aged care facilities and community amenities. In these days of tight fiscal policy and high community expectations, Local Government is undoubtedly accustomed to being asked to ‘do more with less’ – a factor that is further compounded by their restricted ability to raise revenue through rates and user charges. Be that as it may, there will surely come a time when there are quite simply no more funds available - and on current trends it appears that that time is rapidly approaching. With that in mind, I believe that the only way that we can possibly hope to address these issues with any level of success, is for all levels of government to work together in a co-operative and equitable manner to develop the facilities and services that are needed. After all, the population continues to age on a daily basis - and that leaves no time for political ‘buck passing’.

MORE ENGINEERING PROFESSIONALS TO RECEIVE A PAY RISE – BUT THE VALUE WILL BE LESS STEEL STANDARD MAKING AN IMPACT EVERYDAY

Over half (52 per cent) of engineering, construction & property industry employers will give their staff a pay rise of less than 3 per cent in their next review, while 11 per cent will not increase salaries at all. That’s according to the 2018-19 Hays Salary Guide. Based on a survey of more than 3,000 organisations, the recently released Hays Salary Guide shows a further 28 per cent will increase salaries between 3 to 6 per cent while 9 per cent will raise them by 6 per cent or more. Compared to their last review, when 17 per cent of engineering, construction & property employers gave no increases and 15 per cent increased by 6 per cent or above, the findings show that more professionals will receive an increase but fewer will receive a raise at the higher level of 6 per cent and above. Despite this, the engineering, construction & property industry remains more generous than most. On average and across all industries, 18 per cent of employers will give staff an increase of 3 to 6 per cent. Just 6 per cent will increase by 6 per cent or more. Engineering workers however have even higher expectations for a salary increase, with 23 per cent expecting to receive 6 per cent or more. Employees have also prioritised a pay rise. Two-thirds (67 per cent) say a salary increase is their number one

Construction Engineering Australia • June/July 2018

career priority this year. If their employer doesn’t offer a pay rise, almost half (48 per cent, up from 45 per cent last year) will request one. The Hays Salary Guide also found: • 43 per cent of employers expect to increase permanent engineering staff levels in the next 12 months, far exceeding the 8 per cent who say they’ll decrease; • Meanwhile 25 per cent expect to increase their use of temporary and contract engineering staff, also exceeding the 13 per cent who anticipate decreasing in this area; • 25 per cent of organisations now employ temporary and contract engineering staff on a regular ongoing basis and another 49 per cent employ them for special projects or workloads; • Business activity increased for 74 per cent of employers in the past 12 months, while 77 per cent expect it to increase in the next 12 months; • 40 per cent foresee a strengthening economy in the coming six to 12 months; • 32 per cent of employers say staff turnover has increased in their organisation over the last 12 months; The annual Hays Salary Guide is now in its 40th year.

The steel used to construct fences, lighting poles, steel framed houses and shelves in major retailers is the focus of a newly published standard backed by Australian research and the latest technology. “The type of steel covered by this standard, often referred to as light gauge steel, is everywhere,” said CEO of Standards Australia, Dr Bronwyn Evans. “Not only is it in the shelves and racks of popular retailers and major warehouses around Australia, but many shopping centres will also use this steel in construction, proving the far-reaching impact of the standard.” AS/NZS 4600:2018, Cold-formed steel structures has been published following extensive consultation with stakeholders across Australia and New Zealand. This standard also has the potential to be a primary reference in the National Construction Code 2019. “World-leading research undertaken by Australian experts has featured prominently in this standard,” said Dr Evans. “There is also a brand new section on fire design guiding the use of this steel in mitigating the impact of fires.” “This new standard is a quantum leap forward for the steel industry,” said Chair of the Standards Australia Technical Committee responsible for the standard, Professor Greg Hancock. “This is a world leading standard which places Australia at the top of the list in terms of the most innovative steel consumers.” “The benefit of this standard goes well beyond the steel industry,” said Dr Evans. “With such widespread use of this steel, the Australian and New Zealand public as a whole have the potential to see the changes intended by this standard.”

SURGE IN COMMERCIAL BUILDING APPROVALS DRIVES UP JOBS GROWTH

The latest ABS building approvals data shows a 13 per cent rise non-residential building approvals recorded over the 12 months to April 2018. Denita Wawn, CEO of Master Builders Australia said, “This surge in commercial building, including the construction of offices and new facilities in the education, health and aged care sectors has been a major driver of jobs growth and is set to continue.” “In the past year alone, the industry created more than 100,000 new skilled jobs, accounting for more than 1 in every 4 new jobs created. That means employment growth in building and construction was 9.6 per cent, three times the rate of jobs growth in the wider economy,” she said. “More than 370,000 small builders are playing a key role in kicking the surge in jobs growth along. People should pay more attention, there are more small businesses in building and construction than any other sector in the economy,” Denita Wawn said. “In the residential building sector, the total number of new dwelling units approved in April was 18,701, up by 1.9 per cent over the year, supporting Master Builders’ view that the trough in the housing construction cycle is likely to be moderate and short lived,” she said. “Continued growth in the work done by the industry is forecast to continue but it can’t be taken for granted. Investment decisions and business confidence, particularly in the commercial construction sector are heavily impacted by the policies of political parties,” Denita Wawn said. 6

FINAL REPORT INTO ‘SECURITY OF PAYMENT’ LAWS WELCOMED Master Builders Australia has welcomed the release of the report by Mr John Murray AM following a comprehensive review of various current Security of Payment regimes operating around Australia. “Everybody who is entitled to be paid, should be paid. Security of Payment is a vital function as it protects all building industry participants and ensures that businesses, and therefore their workers, get paid,” Denita Wawn, CEO of Master Builders Australia said. “The 300+ page report is a comprehensive contribution to what is an important issue for many participants in the building and construction industry, right up and down the supply and contracting chain,” she said. “Mr Murray should be commended on the extensive work undertaken to complete the Report which is a welcome contribution to this policy debate,” Denita Wawn said. “Security of Payment law assists in helping industry ensure businesses receive

payment when due, however the various regimes have become more complex and divergent in recent years,” she said. “Master Builders has long supported the goal of greater uniformity and consistency of Security of Payment law across the states and territories to increase industry understanding, clarify uncertainty, reduce complexity and boost payment compliance outcomes,” Denita Wawn said. “The history of Security of Payment law shows that more regulation does not always mean better outcomes on the ground, particularly for small subcontractors, and urged all stakeholders to consider the reports 86 recommendations in a sensible and practical way,” she said. “We will carefully consider the report and its recommendations following extensive consultation with our 32,000 members across the country. Naturally there will be a range of views given the existing differences from one jurisdiction to the next, and we hope the focus can be on finding common ground,” Denita Wawn said.

SPECIAL REPORT

Smart Cities Improving standards of urban living by Jonathan Wilkins, Marketing Director, EU Automation The United Nations has reported that by 2050, 66 per cent of the world’s population will live in urban areas. Escalating numbers of urban residents has increased the strain on public services, infrastructure and resources. One potential solution to this is smart technology, which is being used to improve quality of life for growing populations around the world. Here, Jonathan Wilkins, marketing director at obsolete equipment supplier EU Automation, discusses developments in some of the world’s most advanced smart cities. Across the globe, cities are becoming smarter, by incorporating sensor-based Internet of Things (IoT) technologies and city-wide initiatives to try and improve the lives of the residents. Lux Research has suggested that the world will deploy a trillion sensors by 2020, drastically increasing the amount of available data from the world’s cities. A growing number of nations are announcing their commitment to smart city development. In India, for example, Prime Minister Narendra Modi announced a $7.4 billion initiative with the aim of creating 100 smart cities by 2020. In Latin America, Panama is emerging as the region’s first smart city in an attempt to solve traffic congestion and other problems in the city. In Rwanda, Kigali is being transformed into a smart city, optimised for urban living. With so many new players emerging, we look at some of the leading smart cities, setting the example for the rest of the world.

Singapore The island city state of Singapore can be regarded as the world’s premier smart city. The ambitious Smart Nation programme was launched in 2014 and Singapore has been at the forefront of the smart city movement ever since. The island already boasts fibre network access across its 8

Construction Engineering Australia • June/July 2018

entirety, three mobile devices for every two people and a huge network of sensors and cameras providing a large pool of data for analysis. Singapore’s sweeping effort is likely to impact the life of every single resident. At the moment, 80 per cent of residents live in apartments maintained by the Housing and Development Board, which has given the government a healthy testing ground for smart technology. Individual apartments are equipped with IoT sensors to measure energy usage, waste production and water usage. It is important that the island monitors these, as Singapore imports billions of gallons of water from neighbouring Malaysia. The IoT devices can feed into vacuum waste management systems, solar panels or water reclamation equipment. IoT technology is not limited to homes. Singapore is also monitoring the health of its citizens and is currently testing a monitoring system for elderly relatives, which notifies a caregiver or family member if a lack of activity is detected. A tele-health system that enables remote treatment for medical care is also being trialled. As a part of its transition to a smart city, Singapore is also testing autonomous vehicles such as shuttles and taxis. By 2020, the government has mandated a satellite

navigation system in all vehicles, providing a wealth of data for location monitoring and traffic analysis. Singapore’s unique geography and political situation has enabled it to test and commercialise ideas without a lengthy regulatory process, so Singapore is likely to remain at the forefront of this change.

Boston The US government announced in September 2015 that it was committing $160 million to support smart cities over the next five years. One city in particular that has embraced smart city technology is Boston, Massachusetts, where technology is being embedded along and underneath the streets. So far, Beacon Street and Massachusetts Avenue have become Smart Streets, with cameras and sensors monitoring navigation and interaction between drivers, pedestrians and other road users. The city is working with mobile network provider, Verizon, to aggregate the data to learn more about road safety hazards and test smart services. Alongside its cameras and sensors, the city has worked with Verizon to develop a web application for data analysis, visualisation and reporting. Boston is a leader in the global Vision Zero initiative, which aims to reduce the number

SPECIAL REPORT

of fatal traffic crashes using technology to collect data on the behaviour of drivers. Boston has also unveiled a number of apps to improve the day-to-day experiences of residents. These include apps for paying parking tickets and reporting potholes. There’s also a mobile app for Hubway, the city’s bike share system, which shows users bike availability in real-time. Like Singapore, Boston has also started testing autonomous vehicles. In 2017, startup nuTunomy Inc. began testing driverless cars in a 191-acre park. The project is set to expand once certain targets have been reached.

Oslo Oslo has implemented city-wide smart technology to make its streets, transport and buildings greener. One piece of technology showing particularly positive results is smart streetlights that respond to weather forecasts and light conditions, which have reduced energy costs for the city by 70 per cent.

Oslo is highly rated for its excellent quality of life and it is now striving to be smarter, more inclusive and more creative. As a part of this, the city runs a regular contest, SmartOslo, where entrepreneurs and startups can pitch their ideas to improve the city. In addition, the city has started a tenyear programme called FutureBuilt, a collaborative project that aims to support climate-friendly urban development by incorporating and integrating new technology. The project involves almost a dozen partners that are working to build climate-friendly buildings and districts. The new facilities will be of high architectural quality and near to transport hubs and one school built as part of the scheme has automated energy recovery and rooftop classrooms. In Oslo, 60 per cent of the city’s greenhouse emissions are generated by the transport sector. The city has embraced electric vehicles (EVs) by introducing incentives to encourage more people to choose these vehicles, such as not having

to pay the 25 per cent sales tax and being able to use the bus lane. The electrical infrastructure has been improved to match, adding 2,000 charging points at key points around the city. There’s a lot of work to be done for our cities to be ready for the increased population and urbanisation of 2050, but in every continent projects and schemes are pioneering new developments, technologies and ideas to improve city life. This is expected to continue as more nations dedicate funding to projects that will help to lead the way.

INTRODUCING

THE NEW ACRS

STEEL TRACEABILITY SCHEME ACRS (Australasian Certification Authority for Reinforcing and Structural Steels Ltd) is finalising development of a new end-to-end traceability scheme for steel to provide a uniform assessment framework across the supply chain. This new scheme complements existing traceability provisions in the ACRS product certification scheme between steel mills, and the subsequent steel processing and fabricating by including traders and distributors.

Why is Traceability so Important? Traceability is a crucial ability for quickly and effectively investigating customer complaints and managing potential product recalls. This links directly to improved quality and product consistency and compliance. Additionally, traceability certification helps identify any root causes of defective products so they can be isolated and any supplier issues dealt with effectively.

Construction Engineering Australia â&#x20AC;˘ June/July 2018

It's often the case that this chain of traceability breaks down within complex manufacturing processes, which is why it's so important to focus on this particular area of the value chain. Finally, mistakes can sometimes happen, where products are inadvertently mixed and dispatched to an unsuspecting customer.

So why choose the ACRS traceability scheme certification? Increasing Demand Compliance mandates are increasing â&#x20AC;&#x201C; as are the associated costs of fines for non-compliance. For instance, traceability is integral to the international

COVER FEATURE

quality standard, ISO 9001 and to the recently released Steelwork Fabrication and Erection Standard, AS/NZS 5131. Customers are also demanding better clarity and confidence that materials supplied to their projects are compliant. ACRS simple end-to-end certification, including traceability, provides the clearest, easiest, and most comprehensive system available for approval authorities, steel suppliers and the public.

Protecting Reputation With competitive pressures on the rise and consumer confidence becoming harder to earn and maintain, steel suppliers are finding that now, more than ever, there is a need to protect their brands and reputations. ACRS expert product certification scheme provides the best available protection for compliant steel product suppliers and differentiates them clearly and effectively from non-compliant competitors. This benefit will be significantly enhanced by ACRS traceability certification of trading and distribution sources, where appropriate.

Increasing Customer Satisfaction and Safety In the event a problem occurs, manufacturers are able to minimise the impact by only recalling those items with the specific serial numbers that were built with the faulty component, material or process, significantly reducing expenses, customer impact and reputational damage. ACRS certification of products and traceability of materials substantially reduces the likelihood of supply of noncompliant materials.

WHY HAS ACRS DEVELOPED A STEEL TRACEABILITY SCHEME? The impetus for the ACRS scheme and benefit for ACRS certificate holders and public safety is driven by the increasingly recognised need to:

Improving Internal Quality Controls Internationally, suppliers are turning to traceability solutions to help close some of the information gaps which exist in increasingly disparate, global supply chains, to track data and to meet customer safety and demand requirements. ACRS rigorous assessment delivers the most comprehensive system available, enabling suppliers to refine and improve their systems.

INDEPENDENT, EXPERT, THIRD PARTY CERTIFICATION The only way to be truly sure that the materials being used conform fully with the appropriate Australian and New Zealand Standards and are fit for purpose, is through independent, expert, third party validation and certification. ACRS provides a fully independent, expert assessment and certification for both Australian and internationally sourced construction steels, including reinforcing steels, structural steels and prestressing steels. All ACRS auditors are fully qualified metallurgists with many years of experience working with steels. ACRS certification makes checking for compliance with the relevant Australian and New Zealand Standards easy. It demonstrates INDEPENDENTLY and EXPERTLY that the supplier consistently meets the Standards stated on the certificate. By using ACRS certified construction steels, builders and contractors can be confident that they are getting the AS/NZS compliant materials that they ordered, and engineers and building certifiers can be confident that steel meets the requirements of the Building Code and associated Standards.

WHAT ARE YOUR TAGS REALLY TELLING YOU? Your products may arrive with tags, but what do they really tell you? While at first glance the example on the left may appear to tell you all you need to know (there’s even a reference to an Australian Standard) it’s missing some CRITICAL information, including the manufacturer and point of origin. The example ACRS tag on the right provides all of the information needed and, most importantly, the validity of the certificate number and other information can be checked and verified online quickly and easily at: www.steelcertification.com

Construction Engineering Australia • June/July 2018

AREN’T TEST CERTIFICATES THE SAME THING? Test Certificates, ARE NOT the same as ACRS independent certification. Test certificates from the supplier are simply a “snapshot” of the manufacturer’s own test results of the material on the certificate, not its regular supply. ACRS certification demonstrates INDEPENDENTLY and EXPERTLY that the supplier manufactures consistently to the Standards stated on the certificate. Unless you are going to check and validate EVERY single test certificate against EVERY delivery, you should check the ACRS certificates for the manufacturer and supplier instead. For further information about the validity of certification for any materials being supplied into your project, please visit the ACRS website: www.steelcertification.com, or contact ACRS on (02) 9965 7216.

Beyond checking the supplier’s ACRS certificate, product markings and tags, there’s no need for you to make any further checks on ACRS certified materials. • No more checking materials properties against technical specifications; • No more checking batch numbers against the test certificates. In addition to factory production control audits and independent testing, the ACRS scheme provides regular review and analysis of all products manufactured and supplied by the certified supplier. This makes matching material to conformity documentation simple and effective for the customer and for any verifier. ACRS' Product Certification Scheme provides certification of reinforcing and prestressing steels, structural steels and associated products against a wide range of applicable Australian and New Zealand Standards and specifications.

ACRS 'END-TO-END' TRACEABILITY What Does End-to-End Really Mean? First, let's define ‘end-to-end’. When we say ‘end-to-end’, we're talking about the ability to track information on all raw materials, components, and associated processes across the supply chain, including the design, manufacturing, supply and delivery phases. ‘End-to-end’ traceability is directly comparable to ACRS product certification scheme’s cornerstone ‘All products, all locations rule’ which has provided market confidence in steels supplied under ACRS product certification for nearly 20-years.

Enhancing the ‘Chain of Certification’ Construction steels manufactured to AS/NZS Standards can be rendered non-conforming by poor transformation, e.g. through such processes as cutting, bending and welding. Certification systems that only assess the mill of manufacture do not provide for validated performance to Standards of the as-delivered product. In steel reinforcing materials, the ACRS scheme, through its certification of steel reinforcement (“rebar”) processors and the mills of manufacture, provides a rigorous mechanism for “bookending” the manufacture and transformation. This 'chain of certification' provides a vital link between the steel manufacturer and the construction site. For any steel to be ACRS certified, it must have been manufactured by an ACRS Certified supplier. Any break in the ‘chain of certification’ of the mill and the processor means the steel delivered to site is not ACRS certified.

CASE STUDY

Heritage Reborn

Stramit products key in heritage cathedral roof remodelling Originally built in 1848, the imposing and majestic St. Stephen’s Cathedral is a standout feature of the Brisbane city skyline. Nestled amongst the tall office buildings of the thriving city, the grand Gothic revival building is an elegant nod to Australia’s historic architecture and tradition. Maintaining the stunning cathedral is no easy feat with its classic sandstone masonry and delicate stained glass windows – it requires special attention. So when the roof of the Cathedral fell into disrepair, great care, high-quality materials and expert workmanship were needed to guarantee the safe removal and installation of a new roof. St. Stephen’s is a heritage listed building and so must adhere to the Queensland Government’s Conservative Management Plan, a plan which works to ensure the heritage values of a structure are meticulously conserved and managed. Turning to Stramit, one of Australia's premium manufacturers of roll-formed steel building products, as well as award-winning roof installation experts, Certified Roofing – the remodel brief was specific. “Not only did the chosen roof material need to be of the highest quality to ensure many more years of withstanding the harsh Queensland weather,” says Mick Bentham, director of Certified Roofing. “It also needed to seamlessly blend in with the historic architecture of the building, rather than overtake it.” With this in mind, Bentham opted for Stramit Speed Deck Ultra for the entire roof remodel. “I have always been fond of the sleek look of Speed Deck Ultra, its strength of internal clips and backing by a quality name was important,” explains Bentham. 14

Offering excellent durability, Stramit Speed Deck Ultra’s fastenings are protected beneath the decking and can outlast through-fixed roofing – making it perfect for commercial roofing applications. Bentham says the material choice was an easy one. “Not only are the sheets light, Speed Deck Ultra also has a large water-carrying capacity and weather-tightness,” he says. Bentham says the project was not without its challenges. “It was not realised until the scaffolding went up that we tested the surface paint of the roof and found it contained bonded asbestos fibres,” he says. Due to the presence of asbestos, the entire approach to the project had to be changed. “With the building being located in the middle of the city and in a high traffic area, great attention was needed for the safe removal of the asbestos so we engaged 470 Group who specialise in asbestos removal” explains Bentham. “We also had to make sure all Workplace Health and Safety regulations were carefully complied with throughout the removal.” Also challenging was the discovery of 200mm x 30mm thick hardwood timber planks butted together that the old roof was fixed to. “Once this was realised we installed new battens and brought the roof structure back up to standard,” says Bentham. Another aspect of the remodel that proved challenging, was for the original roof ventilators to be re-produced. “The Archdiocese Services wanted us to re-create the original roof ventilators which can be seen on an old black and white photo of the cathedral,” explains Bentham. “Removed from the roof somewhere between the 1900s and 1950s – there are absolutely no plans, drawings or information on the ventilators in any records – all we had as a reference was the black and white photo taken in the 1800s and nothing more.” Thankfully, with the help of F & M Fabrications the ventilators were re-created and placed in the same positions as seen in the heritage photo. Bentham describes the evolution of the cathedral roof as fascinating, “there’s little information on the roof’s past, but we know it was originally slate then replaced with galvanised metal sheets,” he says. “For the new roof we’ve used 0. 48mm BMT Colorbond® in Jasper®.” The Archdiocese Services chose the colour Jasper® which was the closest match to the old roof colour and perfectly suited the traditional architecture of the building. By the end of the installation, Bentham says the St. Stephen’s community loved the results, “indeed it is surprising for many that we were able to retain the traditional look of the cathedral, using advanced modern materials,” he says.

COMPANY PROFILE

TITAN’S ‘ONE STOP SHOP’ DELIVERS MAJOR BENEFITS FOR TRUCK AND CONSTRUCTION EQUIPMENT FLEET OWNERS With a company history tracing back to the establishment of the Electric Wheel Company in 1890 in the USA, Titan is the largest integrated provider and service specialist of tyres, wheels, tracks and axles in Australia. In fact, Titan Australia is the only company in Australia to manufacture and supply both tyres, wheels and undercarriage for tracked equipment. A far cry from its humble beginnings producing wheels for wagons and farm implements in Quincy, Illinois, the name Titan is now synonymous around the world with the manufacture and supply of high quality wheels, tyres and undercarriage for everything from 4WDs, recreational vehicles, buses and trucks through specialist mining equipment, agricultural equipment, and construction and earthmoving equipment of all sizes. Needless to say, this ‘One Stop Shop’ approach is delivering significant benefits to construction equipment and fleet owners across Australia. Adam Oakenful, Chief Operating Officer with Titan Australia, explained: “Whether it’s civil contracting or general construction sector, the majority of operators in the construction sector tend to have an extremely diverse fleet of vehicles and equipment.” “From small trucks, 4WDs, and compact equipment, through to tippers, concrete trucks, low-loaders and large equipment

Construction Engineering Australia • June/July 2018

such as excavators, dozers, front end loaders and other construction equipment, the range of tyres, wheels, track and undercarriage components required to keep these fleets operational on the worksite can be extensive to say the least.” “What’s more, something as basic as a damaged tire, wheel or track on one piece of equipment, can bring an entire worksite to a standstill – and even on a relatively small project, that equipment downtime can end up costing a fortune.” “Needless to say, managing tyre, wheel and track repairs, replacements and other maintenance for such a diverse fleet can be an extremely onerous task and in many instances, it can result in having to deal with multiple suppliers for different components,” he said. “By bringing everything together under one roof, we’re able to streamline the entire process for our clients,” Adam Oakenful added. “Whether it’s a wheel repair, new wheels, tyres, scheduled maintenance and repairs to undercarriage components, or replacement tracks, axles or other related parts, we’re able to provide our clients with a single point of contact and a fully-integrated, streamlined service for their entire fleet.” Together with the obvious productivity benefits resulting from having one central supplier for all tyre, wheel and track needs, this unique ‘one stop shop’ capability

delivers a range of other benefits, including consistent quality control across all aspects of the manufacture / refurbishment / supply process. “All of our tyres, wheels and tracks are manufactured by Titan, either locally or globally. And that means we have our own strict quality control over the entire supply chain from start to finish,” Adam Oakenful said. “What’s more, as a global leader and one of the world’s largest manufacturers of specialist tyres and wheels, Titan’s expertise and ‘knowledge base’ is truly second-tonone. This enables us to work proactively with our customers to develop maintenance and supply solutions that not only streamline operations and boost productivity, but also help to reduce operating costs and minimise equipment downtime,” he added. This focus on working with customers to help minimise downtime and operating costs is clearly evidenced by Titan’s refurbishment works. Forming a significant part of the company’s business, Titan provides a full refurbishment, repair and rebuild service for all manner of wheels and tracks. In many cases, refurbishing wheels and tracks can extend the life-cycle of these parts by up to 30%, and can be carried out for significantly less than the cost of new replacement parts - providing significant savings for customers, without any compromise in quality or performance when compared to a new replacement part.

INNOVATIVE SOLUTIONS

High Speed Conveyor machinery used in a new and innovative way The Hills Rockslinger machinery is gaining traction in the construction world as a quick and powerful way to install landscape product. The high-speed conveyor arm has the ability to spread material up to 30 metres away from where the truck is parked, and at an impressive rate of one tonne per minute. Material handling conveyors have been around since 1795, mainly to move large amounts of grain over small distances. Automated conveyors were widely used from 1919 in factories and mines. The jump from slow factory conveyors, to high-speed material handling was made in Eugene, Oregon much more recently. Truck mounted equipment has enabled the amazing system to move to and from site without cumbersome set up and dismantling. “We originally introduced our Rockslinger machinery here in Australia as a method of reloading our EB blower trucks on job sites all over Sydney, but soon realised these versatile, highspeed conveyor machines had a lot more to offer both us and the construction industry,” said General Manager Chris Nattrass. “Not only have they added invaluable efficiency to our Blower Truck business, but we are now regularly using these machines for the supply and installation of bulk landscape materials, such as backfilling pipelines & trenches, stockpiling in awkward areas not accessible by normal tipper trucks, as well as applying the intricate layers of material into bio retention basins.” The Hills Rockslinger advantage is that it offers customers a supply and installation service, including full supply of the desired material, the method of installation, and a professional and thorough experience all round. The Rockslinger makes short work of all types of trench filling and backfilling work

Construction Engineering Australia • June/July 2018

There is also the option to hire the Rockslinger machinery, along with a trained operator, to install a range of products from Sands, Soils, Roadbase and grades of aggregate up to 75mm in diameter. Joel Marsh is dedicated to identifying suitable sites for the Rockslinger trucks, thereby ensuring the company’s customers receive the best possible service. His goal is to allow all projects to run as smoothly and efficiently as possible, and the material application itself to fulfil the customer’s requirements. “We can install pretty much anything from 75mm Ballast through to fine grade sands, as well as Road base and various fill material,” Joel said. “I just love seeing the look on the customers face when they don’t have to get the material in via wheelbarrows, small diggers, or buckets,” he added. The Rockslinger process works by loading the truck mounted body with the required material. The materials then move along the internal walking floor to the rear of the bin. From there the material is fed onto machine’s high-speed conveyor arm and ‘slung’ to where it needs to go. The conveyor arm reaches out as far as six metres allowing it to reach over walls, fences and across barriers or ditches before placing, or throwing the material depending on the site’s requirements. The conveyor arm has the ability to manoeuvre through 260 degrees horizontally around the rear of the truck and can incline to a height of approximately 4.3 metres - making it one extremely versatile piece of equipment. The Rockslinger is also ideal for jobs such as spreading sand in playground areas

PRODUCT FOCUS

Tsurumi’s new NK series 240 volt single phase submersible pump is tough enough for batch plants.

NEW SUMP PUMP FOR ABRASIVE APPLICATIONS A new heavy duty single phase submersible sump pump has been released by Australian Pump. Manufactured by Tsurumi, the world’s biggest manufacturer of electro submersible pumps, the high head single phase pump is ideal for batch plant, construction sites or anywhere liquids or even light slurries are to be handled. Called the Tsurumi NK3-22, the 3” port pump can handle flows of up to 525 lpm. This heavy-duty pump is lightweight enough to be moved around batch plants in an emergency to wherever there is a pump breakdown or extra capacity is required. The high head performance means that heads of up to 24 metres can be handled with ease. Its slimline design also allows it to fit into narrow locations, making it super versatile. The pump’s solids handling capability is based on a semi vortex impeller design fitted with a synthetic rubber ware plate. “The vulcanised wear plate resists abrasion and provides long life and consistent pump performance,” said Aussie Pumps’ Chief Engineer, John Hales. The pump features a double mechanical seal of silicone carbide located in an oil chamber. That oil chamber features a patented ‘oil lifter’ that provides forced lubrication into the mechanical seal. The Tsurumi design helps extend seal life substantially. Hales claims that the semi vortex impeller even allows the passage of large stringy solids. The impeller’s unique design also accelerates the water passing through the pump casing, creating a vortex that assists the smooth transit of solids in suspension.

Water incursion through the cable entry is the main source of failure in submersible pumps. The Tsurumi NK pump is fitted with an anti-wicking cable entry block. This feature protects the motor from moisture wicking inside the cable in the event of the cable being damaged onsite or the end being submerged. Like all Tsurumi pumps offered by Australian Pump Industries, this pump comes with a unique 3-year warranty. Australian Pump expect it to be a big success. “Every batch plant, every construction site, for that matter every hire company servicing the heavy industries should be equipped with these super versatile but relatively light weight pumps,” said Hales Although the pump is built like a tank, it comes in with a weight of only 29 kilos. The maximum solids handling is 6mm spherical solids. The pumps are designed by Tsurumi to have a maximum water depth of 50 metres. That’s a unique feature found only in Tsurumi top quality pumps. Further information on Australian Pump’s Tsurumi range is available from authorised Aussie Pump distributors nationwide, or at: www.aussiepumps.com.au

Combilift’s new 46,500m² global headquarters and manufacturing facility in Monaghan, Ireland is one of the largest manufacturing operations under one single roof in the Republic of Ireland.

SPECIAL FEATURE

Combilift opens new €50 million global headquarters and manufacturing facility Forklift manufacturer and material handling solutions provider Combilift has officially opened its new global headquarters and manufacturing facility in Monaghan, Ireland. Celebrating its 20th anniversary this year, the company also announced that it will be significantly expanding its workforce with the creation of 200 new jobs in the next three years. Speaking at the opening ceremony, the Irish Prime Minister An Taoiseach Leo Varadkar TD said: “Combilift is an incredible home-grown Monaghan success story. When the company was founded 20 years ago, it had three employees, a brilliant concept, and the ambition to make it a reality. Combilift is playing a significant role in Monaghan’s success, and I would like to congratulate Robert Moffett and Martin McVicar and everyone at Combilift on their achievements to date and wish them every success for the future.” Built at a cost of €50 million, the investment in the new 46,500m2 facility will allow Combilift to realise its ambitious growth plans. Speaking at the official launch, Combilift Managing Director Martin McVicar, said: “We have employed an additional 230 people since we announced our plans for this factory in 2015 and the combination of this state-of-the-art production plant and the growing skilled workforce will allow us to double production within the next 5 years.” Combilift currently exports 98% of its products to 85 countries including Australia, through its 250-strong international dealer network.

CEMENT + CONCRETE

REDUCING CEMENT PRE-HYDRATION COULD IMPROVE QUALITY GCP Applied Technologies Inc. presented a research paper on improving the quality of cement from vertical roller mills by reducing pre-hydration during the recent 25th ASEAN Federation of Cement Manufacturers Technical Symposium & Exhibition in Indonesia. The company also showcased two new cement additive ranges—the TAVERO™ VM grinding aids and OPTEVA™ HE quality improvers. Compared with ball mills for cement production, vertical roller mills require a smaller plant footprint and offer greater energy efficiency and narrower cement particle size distribution. Cement produced in vertical roller mills, however, sometimes exhibits lower strengths and longer initial setting times as compared to ball-milled cements made with the same raw materials. “As more and more cement companies introduce vertical roller mills in their production, it was important for us to deliver solutions that can help optimize cement production and quality,” said Robert AuYeung, Asia Pacific director of marketing, GCP Applied Technologies. “Our research found that using suitable grinding aids and reducing water spray could limit cement pre-hydration and improve cement compressive strength from 1.5 to 3 MPa at all ages tested. Similarly, initial setting time was also shown to have a modest reduction of 15 minutes.” To that end, GCP has introduced two new additives that deliver a range of benefits during cement production in vertical roller mills: • TAVERO™ VM grinding aid additives, which help stabilize vertical roller mills during production by reducing water injection requirements and cement pre-hydration. 26

Construction Engineering Australia • June/July 2018

At the same time, they improve cement performance by delivering higher strengths and shorter setting times. • OPTEVA™ HE quality improvers are cement additives that provide options for gaining higher early (HE) strength and are particularly effective for challenging cements. “TAVERO™ VM additives enable more stable VRM production with less usage of water and potential fuel savings with reduced need to heat the mill. It also enables better cement quality with lower energy consumption and less wear on equipment,” AuYeung said. “OPTEVA™ HE additives enable greater use of supplementary cementitious materials in place of clinker and increasing use of alternative fuels. This reduces greenhouse gas emissions and also lowers the costs of cement production.” GCP has more than 80 years of experience producing high-quality grinding aids and performance enhancers. The company’s grinding aids have helped producers improve cement productivity by up to 20% without additional production costs. Similarly, GCP’s quality improvers have helped improve mill production by up to 20%; early- and longterm compressive strength by up to 30%; and helped lower energy consumption by about 25%, all without any loss of cement quality.

“Our cement additives and water-reducing concrete admixtures reduce air pollution equivalent to more than 10 million cars annually,” AuYeung said. “Through the use of GCP’s cement additives globally, about 3,000 megawatt hours of electricity are saved daily that’s equal to the daily energy consumption of half a million families.” The company will continue to expand its comprehensive portfolio of additives for cement production under the OPTEVA™ and the TAVERO™ brand with new products rolling out in the future. “We continue to reinforce our position as a global leader in cement additives by providing innovative solutions to our customers,” said Naren Srinivasan, chief strategy, marketing and development officer. “GCP Applied Technologies offers cement producers a complete portfolio of products and services, enabling them to lead in cement quality, cost efficiency and sustainability.”

ABOUT GCP APPLIED TECHNOLOGIES GCP Applied Technologies is a leading global provider of construction products technologies that include additives for cement and concrete, the VERIFI® in-transit concrete management system, high-performance waterproofing products, and specialty systems. GCP products have been used to build some of the world’s most renowned structures. For further information, please visit: www.gcpat.com

CONCRETE INSTITUTE

THE PERFORMANCE OF CONCRETE SYMPOSIUM

AUSTRALIA

OVERVIEW

WHAT THE EXPERTS SAY

Concrete is the most widely used building material in the world. Despite the many changes in the construction industry globally, concrete continues to be the benchmark material for long lasting, durable structures. As such concrete continues to be researched and developed.

“While advances have been made in admixtures, binder and aggregate production, testing, and repair materials, the root cause behind many of our concrete problems is neglect of the basics. All areas of the concrete industry need to have an understanding of concrete the material and how it works. Designers must know whether their designs can be built. Constructors must understand the impacts of placing, compaction and curing of concrete to achieve the specified performance requirements. You only get one chance to ‘get it right’, with concrete, so asking the right questions at the right time is essential to getting the right outcome”. Michael van Koeverden, Principal, CQT Services

While new materials show promise in the construction industry they are often made from natural resources that are simply not found in quantities abundant enough to compete with, or even replace, concrete. It is for this reason that advances in concrete, and the materials that are used in it, are always being further developed, along with enhancements to generate special properties, or to achieve superior characteristics that may provide long-term durability, sustainability, and performance. However, it is vital that all stakeholders in the concrete industry have a basic understanding of the concepts involved to ensure that the performance of the material is not compromised. This applies to anyone in structural and civil design, project management, concrete construction, and concrete technology. This event is Part 1 of a series on the Performance of Concrete. It will provide an update on the changes in Australia with respect to materials and conditions that impact the performance of concrete, and how these impact concrete specification, construction, and ultimately performance in this country.

“Raw materials are the life-blood of the concrete manufacturing process. The quality and consistency of concrete constituents ultimately affect the finished product, and as such, great care should be given to the assessment of these materials. A sound understanding of their limitations and impact on the final product needs to be understood. Presentations by experts in these fields are vital for the industry to enhance its skills with regards to local concrete materials.” Andre van Zyl, Technical Services Manager, Concrete Institute of Australia

WHO SHOULD ATTEND? This event will be of great importance to professionals in the fields of: • • •

Structural engineering, design and specification Concrete construction Road, rail and water authorities

It is also a great opportunity for young graduates and professionals to learn more about what goes in to our most widely used construction material, and what it does!

WHEN AND WHERE? This event is coming to the following locations throughout July

Alkali-silica reaction (ASR) is when aggregates containing silica react with alkali hydroxide in cement to form a gel that swells with water from the surrounding cement paste or the environment. This can then cause enough pressure that the concrete becomes damaged. ASR is typically indicated by random map cracking and, in advanced cases, closed joints and attendant spalled concrete. Why is it important for designers and specifiers to know about ASR? There are materials used in concrete that can help reduce the risk of ASR occurring; certain structure types, requirements and areas that can increase the risk of ASR, and new testing methodology available to predict the level of risk!

The Performance of Concrete How much do you know about concrete materials and the impact they have on the performance of the finished product? On the other side, how much do you know about what impact the choice of materials has on concrete depending on where it is placed? The Concrete Institute of Australia is pleased to be hosting a Symposium at a number of venues around Australia, and here are some questions that you may find the answers to, along with much more, at the event.

How much do you know about other cement types? General purpose cement (Type GP) is the main type of cement used in the majority of concrete construction work in Australia. However, there are a number of other cement types available, as outlined AS3972 General Purpose and Blended Cements. These cement types include â&#x20AC;&#x201C; sulfate resistant cement (Type SR), shrinkage limited cement (Type SL), low heat cement (Type LH), high early strength cement (Type HE), and general blended cements (Type GB). Why is it important for designer and specifiers to know about all the various cement types? Blended cements are manufactured for specific purposes, designed to provide particular properties of the hardened concrete that will assist with its performance for its specified environment and designed use.

How much do you know about alkali-silica reaction? Alkali-silica reaction (ASR) is when aggregates containing silica react with alkali hydroxide in concrete to form a gel that swells with water from the surrounding cement paste or the environment. This can then cause enough pressure that the concrete becomes damaged. ASR is typically indicated by random map cracking and, in advanced cases, closed joints and attendant spalled concrete. Why is it important for designer and specifiers to know about ASR? There are materials used in concrete that can help reduce the risk of ASR occurring; certain structure types, requirements and areas that can increase the risk of ASR, and new testing methodology available to predict the level of risk! 36

CONCRETE INSTITUTE NEWS

How much do you know about acid sulfate soils? Acid sulfate soils are naturally occurring soils that are formed under waterlogged conditions. These soils contain iron sulfide minerals (predominantly as the mineral pyrite) or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign (known as Potential Acid Sulfate Soils). However, if the soils are drained, excavated, or exposed to air, the sulfides react with oxygen to form sulfuric acid and are known as Actual Acid Sulfate Soils. Why is it important for designer and specifiers to know about acid sulfate soils? Engineering construction in areas of potential acid sulfate soil conditions general lead to exposure and ultimately actual acid sulfate soils. Concrete specified in these areas must be designed with appropriate materials and mix design detail to avoid the risk of short and long-term deterioration and loss of strength.

How much do you know about cold weather admixtures? Whilst most areas of Australia don’t experience weather so cold that it affects concrete placement, the winter months can be conducive to the quality of the concrete. However, in some instances when there are prolonged cold snaps, or construction occurs in areas that are just above 0°C or even below. It can take forever for concrete to harden as the heat of hydration is dramatically affected. Why is it important for designer and specifiers to know about cold weather admixtures? It’s not just a simple solution of picking an accelerator to increase the rate of hydration.

What mix has been specified? Can a blended mix with SCM’s be more beneficial? What is the impact of admixtures on the designed mix? Concrete is the most used construction material in the world. However, there is so much to understand about how it performs in all the various places around the globe in which it is used. The impact of raw materials, manufactured materials, design use, and the environment on the performance of concrete come down to understanding the basics, and putting all the pieces together. The Concrete Institute of Australia’s Symposium on the Performance of Concrete is being held at various venues nationally during July.

NATIONAL PRECAST FEATURE

TECH TALK:

MITIGATING CONSTRUCTION RISK WITH PRECAST At National Precast, we strive to educate and provide assistance to professionals within the construction industry. Our Tech Talk series has been developed to address some of the common queries within the precast concrete space. In this issue, we look at mitigating time, cost, and safety risks using precast concrete.

ABOUT CONSTRUCTION RISK As in every industry, the construction industry endeavours to improve business efficiencies. However, unique challenges arise from complex projects and these complexities can create additional risks. Construction risk begins at a project’s early conceptual stage and ends as the last finishing trade leaves the site. Risks include time extensions from inadequate programming, delays in material delivery, labour disruptions, safety issues, and inclement weather. Risk is heightened where project documentation is incomplete, material quality is poor, safety is lacking or workmanship is tardy. If not properly managed, these construction risks can significantly increase a project’s costs.

Construction Engineering Australia • June/July 2018

PRECAST TO MINIMISE RISK Using precast concrete in construction addresses many risks. While it is likely the oldest type of prefabrication around, off-site manufactured precast arguably offers the biggest opportunity to improve efficiencies and minimise risk in construction today. While precast concrete isn’t a new phenomenon, the construction benefits of using precast are not fully understood, particularly when it comes to reducing risk.

REDUCING THE RISK OF TIME BLOWOUTS Manufacturing precast components can begin as soon as shop drawings are approved. Once precast erection commences, on-site construction and off-site manufacture can be overlapped, reducing overall construction times by up to 75%. Time savings using precast stem from good programming, the benefits of a factory-made environment, a reliable supply of elements that isn’t weather dependent, and speedy construction. There are additional time-saving benefits when a structure adopts a total precast solution (using walls, floors, beams, columns, stairs and lift shafts). For example, when precast flooring

is used, there is minimal formwork and therefore subsequent trades can continue immediately. As well, using total precast maximises use of the crane. The skill levels in precast factories are another definite advantage and the high quality of products delivered to site also helps to speed construction and reduce risk. Precast factories assess and train their workforces, with many employees completing competency assessments for the licensed tasks undertaken in their factory. That means product quality is high and the risk of slowing a project’s program from defective products is minimised. On site, the increased size and availability of mobile cranes has encouraged larger and heavier elements to be produced, which are now easily lifted directly into position after delivery.

REDUCING THE RISKS OF COST BLOWOUTS Just as using precast will shorten programs – which in itself reduces cost and minimises risk – there are other cost efficiencies that can work to counteract a project’s cost blowouts. A solid understanding of the precast process from the start, alongside meticulous planning, working with the precaster, and reduced time on site will reap rewards.

NATIONAL PRECAST FEATURE

During design and manufacture, economies of scale can be achieved by maximising repetition of precast elements. The more repetition there is in terms of consistent shapes and sizes, the less need to adjust moulds in the factory before each pour. Maximising element sizes is also important in reducing cost and this will depend on local transport limits.

MINIMISING RISK WITH GOOD DRAWINGS

While proper construction drawings and document management may not spring to mind as the number one cause of a project’s cost and time blowouts, they can be the silent killer for an array of issues. As such, producing fully detailed working drawings before commencing precast manufacture is essential. With good working drawings, the subsequent shop drawing process which precedes precast manufacture can eliminate many of the time and cost frustrations right from the start.

REDUCING THE RISK OF SAFETY INCIDENTS The construction industry is currently ranked third in the list of annual workplace deaths. As a result, safety costs on site can be significant and anything that can improve site safety is critical. Factories offer the perfect off-site construction solution, removing major parts of a project’s build from the cluttered and busy site and transferring them to a much safer environment. A controlled factory environment is

going to deliver an obvious improvement on site when it comes to safety.

HOW TO FIND OUT MORE For more information on reducing construction risk with precast refer to Mitigating Construction Risk (National Precast, 2013) and for advanced knowledge of design, manufacture, and the use of precast concrete, refer to the Precast Concrete Handbook (National Precast, 2009) - both available for purchase from: www.nationalprecast.com.au

NATIONAL PRECAST FEATURE ACKNOWLEDGING INDIGENOUS CULTURE WITH GRAPHIC CONCRETE™

PRECAST CONCRETE CHANGING THE GAME AT OPTUS STADIUM PRECASTER: DELTA CORPORATION BUILDER: BROOKFIELD MULTIPLEX ARCHITECT: HASSELL, COX AND HKS ENGINEER: ARUP CLIENT: STATE GOVERNMENT OF WESTERN AUSTRALIA Whether you’re footy-mad, an avid cricket supporter, or a rugger devotee, you’re bound to find an appreciation for the new Optus Stadium in Western Australia. Exhibiting an innovative design committed to a ‘fans first’ approach and acknowledging Western Australia’s sporting, cultural and Aboriginal history, the renewed Stadium offers fans an exciting new venue that is a tribute to the extensive possibilities of architectural precast. When the world-class stadium opened in January 2018, it was met with local and international acclaim from both the construction sector and general public. Optus Stadium has already hosted a range of blockbuster AFL matches and is set to open up more opportunities for Western Australia to host high calibre national and international sporting, arts, and music events.

FIRST IMPRESSIONS COUNT It is well-documented that the aesthetics of our structures have an impact on a society’s wellbeing, and the new Optus Stadium is a fine 40

example of where precast concrete is making its contribution. When the lights go on, it is the beautiful precast exterior that wraps the action within. A stunning precast architectural wall façade featuring 4,000m² of panels manufactured by National Precast member, Delta Corporation, creates a wonderful first impression for Stadium visitors. Delta’s Executive Director, Matt Perrella, says the client chose precast for its architectural finishes and the overall effect is imposing and stunning. “It’s virtually the first thing you see, and it looks amazing,” Mr Perrella explains. Although specified as a Class 2 finish, the coloured precast concrete façade is of exceptionally high quality. With images etched into selected segments and sandblasted at varied depths, the panels exude contrasting architectural finishes - some with a smooth surface and others with exposed aggregate. Integral colouring using pigments in the concrete mix has produced raw, earthy tones and a saw tooth profile has been achieved using custom moulds that were fabricated specifically for the project. Mr Perrella says his team has found working on a project of this nature both interesting and challenging. “We enjoyed being part of a project that’s somewhat different to our usual production and this one really pushes the boundaries of what can be achieved with architectural precast,” Mr Perrella details.

The commitment to a ‘fans first’ stadium has resulted in an innovative design that isn’t only delivering an incomparable event atmosphere; it also acknowledges the site’s rich Aboriginal culture and history. This has been done by having the artwork etched into the surface of the precast panels with graphic concrete™. The artwork aims to encourage Stadium visitors to reflect on and appreciate the area’s Indigenous history. Through the use of graphic concrete™, Delta worked in collaboration with National Precast Industry Partner and graphic concrete™ specialist, ramsetreid, to manufacture a spectacular surface relief that showcases the Nyoongar Aboriginal language and stories. Artwork was provided by the State Government of Western Australia. “While we use varying degrees of sandblasting very regularly, the graphic art on this project was something really spectacular,” Mr Perrella says.

VERSATILIY THAT GLOWS The new Optus Stadium’s spectacular bronze façade offers fans a glowing first impression. By day it reflects Western Australia’s unique geology and history and by night, the elaborate LED lighting radiates the home team colours. As the new jewel in Western Australia’s crown, it is no wonder the glory of the new structure has been met with local and international acclaim.

41 X : A DESIGN JOURNEY PROJECT: 41X PRECASTER: EURO PRECAST CLIENT: AUSTRALIAN INSTITUTE OF ARCHITECTS ARCHITECT: LYONS ARCHITECTURE Grand heritage and striking contemporary infrastructure fuse to create one of Melbourne’s most recent architectural delights. As the striking new national office for the Australian Institute of Architects (AIA), 41X was the subject of a two-stage design competition held by the Institute’s National Council and won by Lyons Architecture in 2008. Completed six years later in 2014, the building continues to stand as something of an architectural marvel in the heart of the CBD. Standing proud on a pocket-sized 285m2 allotment on the corner of Exhibition Street and Flinders Lane, 41X is a 22-storey tower and a hub for architecture, AIA staff, and the general public. With precast concrete manufactured by National Precast member, Euro Precast, playing an integral role in the building’s aesthetic and sustainability ambitions, there’s a growing interest for astonishing architecture using offsite manufacturing methods.

NATIONAL PRECAST FEATURE

A HYBRID PUBLIC-COMMERCIAL DESIGN According to Director of Lyons Architects, Adrian Stanic, when embarking on the design journey, the focus was on creating a hybridised public and commercial space with extensive sustainability benefits. This idea has been achieved by connecting the city street space with the AIA, which occupies the lower levels of the tower. “Cantilevered higher levels allow wider footpath space at the base of the building, while a strategically placed publicly-accessible stairway and a public perimeter seating merges the public street with the entrance of the institute,” Mr Stanic details. The building’s façade features angular precast concrete fins as a reference to the chiselled masonry aesthetic of Melbourne’s public buildings. Defining a rugged exterior, several of the fins have been strategically cut away – or chiselled – to make room for the elevated public spaces that are highlighted with refreshing, bright green soffits.

PRECAST PERMANENCE WITH TRANSPARENCY A hybrid public-commercial space was explored by contrasting the permanence and weight of heavy stone-like materials with corporate transparency. “An idea that has been around for thousands of years is the idea of how stone and masonry is used to signify permanence in public buildings,” Mr Stanic explains. “They tend to have a significance that often can relate to the public domain.” The success of this architectural vision relied heavily upon the use of precast concrete - a product that has allowed the building to be as extravagant as it is durable. Proper design detailing combined with precast’s high-quality manufacturing process allowed Lyons to make their mark for generations to come, through what is a timeless contribution to the city.

OFFSITE MANUFACTURE ENABLES CONSTRUCTION EFFICIENCIES As well as accommodating the architectural design, precast concrete delivered construction efficiencies that were imperative for smooth operations in a congested city location. Euro Precast was contracted to manufacture a variety of prefabricated concrete elements for the project including fins for the east and west façades, external façade panels to the north, and internal lift, stair and service room panels. As well, 84 horizontal sunshades, 133 columns, and 6,200m2 of BubbleDeck flooring across 230 decks were manufactured by the precaster. Euro Precast’s Director, George Spiropoulos, says the use of precast concrete minimised onsite material and labour. “BubbleDeck precast floor panels and precast concrete columns reduced the need for formwork and maximised construction efficiency,” Mr Spiropoulos explains. “Unique external precast concrete panels of complex geometry were integrated with high performance glazing as part of a complete energy efficient facade system.”

CARBON NEUTRALITY WITH 5 STAR RATINGS The architectural brief employed a range of sustainability initiatives that accounted for embodied energy, base building operational energy, transport, and waste. Striving to achieve carbon neutrality, Lyons joined forces with AECOM to develop solutions that took a holistic approach the building’s carbon cycle. Designed to achieve a net zero carbon footprint over its 30-year operating cycle, 41X is one of the first strata-titled commercial office buildings in Melbourne to target carbon neutrality. With 5-star Green Star and 5-Star NABERS Energy ratings, 41X exemplifies how structures can have a positive impact on the development of their cities through cutting-edge and environmentally responsible buildings. 41X exemplifies unity between the general public and the architectural, engineering and building professions. Making a bold statement about the value of design, the AIA’s new headquarters is reinforcing the value of architecture to the sustainable growth of Melbourne’s city.

NATIONAL PRECAST FEATURE

NATIONAL PRECAST’S TENDER SERVICE: YOUR ONE-STOP SHOP FOR PRECAST The thought of using a tender process may seem like a winding trip down a precariously long road for some civil and infrastructure companies. However, this needn’t be the case when the process is handled the right way. National Precast’s Tender Service provides builders and developers with a userfriendly, trustworthy, and cost-effective tender process. National Precast’s Chief Executive Officer, Sarah Bachmann, says the Association’s online Tender Service has made their nation-wide network of accredited precast manufactures easily available to the construction industry. “We know that builders and developers are time-poor and often have limited capacity to screen precast manufacturers to work out whether they're suitable to supply a project,” Ms Bachmann admits. “We've made that easy for them, because all of our members have undergone thorough checks before being accepted into National Precast's membership.” The Association’s online Tender Service has been successfully operating since 2015 and Ms Bachmann says it is a go-to service suited to anyone in the infrastructure space. “Because several of our members manufacture precast for both civil and building projects, the beauty is that talking to just one or two of our members can be a one-stop-shop for an entire project,” Ms Bachmann explains.

The Tender Service has been developed in conjunction with architects, builders, engineers, and precast manufactures, to help ensure a user-friendly process for all parties involved. Not only does this service allow for a smooth process for the client and precaster, but Ms Bachmann believes it also allows for professional relationships to evolve. “It has shown to be an incredibly time-saving service that also allows builders and developers to start cultivating relationships with our members,” Ms Bachmann says. “That has flow-on benefits too, as the precaster – when involved early in a project – will often be able to assist with efficiency and cost saving changes that can easily be implemented.” As a result, the client can be confident that they’re working with accredited and experienced precasters who have passed the Association’s strict membership criteria. Don’t spend all day chasing manufactures to find the best price. Instead, let them come to you. Ms Bachmann invites relevant businesses to supply National Precast with the details of their next job by filling out the required fields on the Association’s website, “then sit back, relax, and wait for the tenders to arrive”. National Precast’s Tender Service is available at: www.nationalprecast.com.au

Developed in conjunction with architects, builders, engineers, and precast manufactures, the National Precast online Tender Service provides a userfriendly process for all parties involved.

PRECAST TECHNOLOGY

Today, the Schachen plant specialises in the planning and production of prestressed structural precast concrete elements and, with its many years of experience in industrial and commercial construction, is an important part of the Müller-Steinag Element AG sales company. The latter unites all of the group's plants that are involved in the manufacture of precast concrete elements. Its portfolio extends from large engineering elements for support structures, prestressed elements and highly load-bearing columns through to noise barrier elements and multi-storey car park systems.

SCHACHEN PLANT: FROM THE SUPPLIER TO THE PARTNER ROLE

Tecnocom developed a flexible mould system with two different types of moulds for the Schachen plant: with the first, a 46 metre-long mould for the manufacture of TT slabs.

2-IN-1: HIGHLY FLEXIBLE MOULD SYSTEM GOES INTO PRODUCTION The Swiss Müller-Steinag Group is continuing to invest in the further development of its Schachen plant. The goal is to not only fulfil the role of a supplier, but also that of a partner with holistic building concepts. To meet this need, the company expanded its own engineering department and the machine pool was extended and diversified. Together with Tecnocom, a Progress Group company, a highly flexible mould system for the manufacture of TT slabs and rod-shaped precast concrete elements was developed and installed. Production started in November 2016 with the manufacture of TT slabs for a major project near Zurich. Large structural elements for precast concrete construction have been produced at the Müller-Steinag Element AG plant in Schachen near Lucerne for over 35 years. Founded in 1981 as Cavag AG, the company concentrated in the first decades on the production and assembly of silos for 46

agriculture, as well as elements for building construction. Since the turn of the millennium and the takeover by the Müller-Steinag Group in 2011, the building construction segment has grown increasingly in importance, and the production and turnover of structural precast concrete elements have increased steadily.

“Each of the group's plants has a core alignment,” explains Thomas Wyss, managing director of the Schachen plant. As far as the Schachen plant is concerned, he says, its alignment has undergone a change in the last ten years. "We want to get away from the role of the supplier. Our goal is to develop into a partner for our customers that can offer its own concepts.” For this purpose, the company expanded its own engineering department and began to extend and diversify the machine pool. “That enables us to no longer act just as a simple supplier of structural elements, but to develop holistic building concepts together with our clients,” Wyss says.

The TT mould can be dismounted from the base frame and replaced by a second mould for the manufacture of rod-shaped precast concrete elements.

HIGHLY FLEXIBLE MOULD SYSTEM FOR THE MANUFACTURE OF TT SLABS AND ROD-SHAPED PRECAST CONCRETE ELEMENTS An important milestone along this route was the investment in a mould system with which TT slabs and rod-shaped structural precast concrete elements can be manufactured according to customer wishes. When it came to choosing a technology partner to work with on the expansion at the Schachen plant, Müller-Steinag Element AG selected Tecnocom, a Progress Group company specialising in special mould systems. “Tecnocom convinced us with their technical solutions,” says Thomas Wyss. The installed mould system consists of a base frame on which two different kinds of moulds can be mounted. Thanks to this flexible alignment, the production can be switched following the manufacture of TT slabs in the first project phase to the manufacture of girders and columns in the

The mould for the production of girders and columns has vertical support frames with a height of up to 2m. These consist of four modules on each side which can be controlled separately by means of electric motors.

second phase. An existing prestressing plant was integrated into the system.

PROJECT-RELATED MANUFACTURE OF TT SLABS The first precast elements made with the new equipment were TT slabs for a project in Leutschenbach near Zurich. The mould was developed and installed especially for the order. It has a length of 46 metres and is equipped with a vibrator system. “The first TT slabs that we manufactured have a length of 10.5 metres and a width of 2.5 metres,” Wyss explained. “They were used in the construction of the new SRF (Swiss Radio and TV) technical centre.” Over 250 of precast concrete TT slabs were produced for the SRF project. With the first part of that project complete, the mould was dismantled and replaced by a second mould for the manufacture of rodshaped components.

The 10.5 metre-long and 2.5 metre-wide TT slabs were used in the construction of the new SRF technical centre near Zurich.

DOUBLING OF OUTPUT THROUGH ADDITIONAL LONGITUDINAL SHUTTERING ELEMENT Using an additional longitudinal shuttering element, the mould can be divided in the middle. “That allows us to produce two precast concrete elements in parallel, which is effectively the same as doubling the output,” Wyss explained. "Thanks to the electric motors, the lateral shuttering elements can be opened wide enough for that."

MANUFACTURE OF ROD-SHAPED PRECAST CONCRETE ELEMENTS WITH HEIGHTS OF UP TO 2 METRES

HIGHLY FLEXIBLE PRODUCT, TRUSTING COOPERATION

The mould for the rod-shaped precast elements also has a length of 46 metres and has vertical support frames to which the lateral shuttering elements are fastened. The support frames themselves consist of four modules on each side and can be moved with the aid of electric motors. The lateral shuttering elements are thus also separately controllable. The variable height of up to 2 metres provides for additional flexibility. “The special feature of this mould is that it can be used to produce concrete elements that are both 2 metres in height and very long,” Thomas Wyss said. The girders and columns are manufactured both in untensioned and pretensioned versions.

For the Müller-Steinag Group, this high level of flexibility is one of the most important properties of the new mould system. Thomas Wyss is satisfied: “We are not only able to produce TT slabs with a variable cross-section, but also various rod-shaped components - for example columns with corbels.” Wyss describes the cooperation with Tecnocom as very good throughout. “Together with their technical know-how and the flexibility of the machines, it was the strong group in the background that enabled us to establish great trust and build a strong cooperative relationship.” For further information, please visit: www.tecnocom.com

2018 Local Roads Congress Councils urge action on road safety Councils need to take immediate action to address the horrific road safety toll. That’s the key message to come out of the NSW Local Roads Congress held in Sydney on 4 June 2018. And they are going to need the help of the NSW and Australian Governments to make a real difference. Councils and experts from across NSW were joined by the President of Local Government NSW, Linda Scott, and Members of Parliament from both sides to develop a way to lower the road toll across NSW. With 392 deaths and more than 12,000 serious injury crashes in 2017 in NSW alone, and the trend going in the wrong direction, the Congress is calling for extra measures to turn the road toll trend around. Presenting at the Congress, Minister for Roads, Maritime, and Freight Melinda Pavey, MP highlighted the new $125M Saving Lives on Country Roads Program as a significant step forward and called for collaboration between all levels of government. The Minister also confirmed the LG Road Safety Program through to 2021. IPWEA NSW President Warren Sharpe OAM called on the NSW Government to build on the excellent work being done in partnership IPWEA (NSW), LGNSW and councils. “Almost 90 per cent of NSW roads are under the control of councils. We’re urging all councils to identify the most effective actions in their own community by developing road safety plans. To do this, they need skilled engineers and technical officers so IPWEA (NSW) has developed new guidelines. Nearly two-thirds of councils now have trained road safety auditors provided through a partnership between IPWEA (NSW) and the NSW Government." "We’re calling on the remaining councils to take advantage of this opportunity,” Mr Sharpe said. “The NSW Government’s transport funding programs provide a once in a generation opportunity for councils to make a real difference to road safety and freight efficiency on local road networks," Mr Sharpe added. “Despite this, our research clearly shows that communities in the bush need additional ongoing financial support. We’ve put the case that Federal Assistance Grants should be re-distributed to regional NSW with city councils able to sustain their income by rating high density development vertically. Any re-distributed funding must be tied to roads,” Mr Sharpe said. The Opposition agrees. Shadow Minister for Transport and Roads, Maritime, and Freight, Jodi MacKay, MP and Shadow Minister for Local Government Peter Primrose MLC, were united in their support of the redistribution of FAG funding at the Congress. IPWEA (NSW) Roads & Transport Directorate Manager, Mick Savage, outlined the importance of additional funding in the bush. “Rural areas produce the food and resources we all rely on in the city. A million dollars a year extra at Moree or Griffith spent on their local road network just means so much more, and when two-thirds of all fatalities are occurring in regional NSW, it just makes sense to provide greater support in our regional areas to lower the road toll," Mr Savage said. The Congress also heard from Dr John Crozier, Trauma Chair, Royal Australasian College of Surgeons, who left no doubt as to the 50

impacts of road crashes. In a confronting presentation, he outlined an ‘average day’ in a hospital emergency ward, including that for every serious injury recorded, there were an additional seven presentations to hospitals from road crashes. NSW Police, Australian Trucking Association, Centre for Road Safety, State Emergency Services, National Heavy Vehicle Regulator and the Newell Highway Taskforce all backed further measures to address improved road safety and transport and road worker safety. Mayor of Parkes, Ken Keith OAM, further called on Councils to develop new cadet Engineers to grow skilled professionals of the future from their own towns. NSW Staysafe Committee Chair Greg Aplin, MP wrapped up the Congress outlining recent successes including compulsory minimum driver training for young drivers but highlighted speeding, drink and drug driving, fatigue and driver distraction as remaining road safety challenges. Delegates adopted a communique calling for the development of a sustainable and more equitable funding model to look after roads, target road safety and open up local road network to more efficient transport to better service our community and drive the NSW economy forward.

IPWEA NSW NEWS

National Cadet Engineering Program IPWEA NSW is recommending that the Australian Government play a role in incentivising Local Government to directly engage Cadet Engineers within Councils across Australia. The delivery and on-going stewardship of critical infrastructure will require qualified and skilled professional Engineers to ensure value for money. IPWEA NSW undertook a skills audit across NSW Councils and collated data from recent membership surveys. The trend is very clear. With 53% of Engineers responding now over 50 years of age, and a skills shortage already evident, it is clear Governments across all levels must act now to immediately incentivise investment in new skilled and qualified Engineers for the future. Only 53% of NSW Councils have a Cadet Engineering program. This is a self-fulfilling prophecy and unless addressed the skills shortage will develop into a crisis scenario. The Government has introduced excellent incentive programs for Civil Construction trainees and apprentices, but how is the shortage of qualified Engineers being addressed? With the right incentive programs, Councils can offer a breeding ground for future professionals to deliver high quality infrastructure and services to their communities. In regional areas of Australia, this offers the opportunity for employing and retaining young innovators of the future within regional townships. We urge the Australian Government to adopt a policy setting that offers support to Councils through a National Cadet Engineering Program. This program should offer initial funding support, and graduated retention payments to Councils to train and grow people for the future. The Australian Government should also investigate ways to partner with Universities and professional associations to deliver fit for purpose training and on-going development. We also urge the Australian Government to support a universal national registration scheme for Engineers for the whole of Australia, and to encourage all States to incorporate this into their own jurisdictions through appropriate legislation (eg NSW Roads Act).

IPWEA (NSW) welcomes record $87.2B investment in infrastructure by the NSW Government Speaking after the NSW budget, IPWEA (NSW) President Warren Sharpe OAM highlighted the diversity of the NSW Government's approach to addressing key infrastructure challenges. "There is a clear recognition by the NSW Government that they need to address both the challenges to take Sydney forward as an economic powerhouse as well as provide the infrastructure within regional NSW to drive the significant employment and decentralisation outside of the Sydney basin,” Mr Sharpe said. "The extensive investment in rail within Sydney including the forward reservation of $3B for Metro West and $5.7B for Sydney Metro City and South West projects means the Government is looking ahead to embed the three cities concept and shift more commuters onto modern accessible rail. Their challenge now is to deliver these alternate transport modes to mitigate the number of cars on city roads," he said. "In regional areas we're seeing record investment in the State highway system with major allocations to the Pacific and Princes Highways. For local roads the Bridges for The Bush ($335M) and Fixing Country Roads ($543M) Programs will provide Councils the opportunity to overcome freight impediments and improve the productivity of agriculture, forestry and other agribusinesses. These works are vital given the reliance on road transport in regional NSW." "The additional $390M for road safety over the next four years is badly needed with 392 fatalities and more than 12,000 serious injuries on our roads in 2017, and the trend has worsened each year since 2014. With Local Government looking after 90% of NSW roads, it is vital that the NSW Government better support local Councils through improved capacity building in pro-active road safety planning, and by funding road safety measures, particularly in regional NSW where over two thirds of fatalities occur," Mr Sharpe said. "We also welcome programs such as the Stronger Country Communities Program.

Whilst smaller in scale, these funds allow Councils in regional NSW to improve the quality of life for their communities by providing improvements to local parks, community halls, playgrounds and sporting facilities," he added. "Perhaps the biggest single infrastructure issue across regional NSW remains water security and wastewater management. The NSW Government's $1B Safe and Secure program provides an excellent starting point however it will clearly not be sufficient to meet the many challenges across NSW. This really is essential infrastructure for the economic prosperity of NSW, and for the public health and social wellbeing of our communities as well as for the protection of our environment,” Mr Sharpe said. "The NSW Government has wisely established funding to investigate the best use of the $4.2B windfall from the sale of Snowy Hydro. They've indicated these funds will be used for 'major state building' projects in regional NSW. We would certainly encourage the Government to investigate using part of the funds to increase the funding for essential infrastructure to address water security and upgrades to ageing sewerage infrastructure across NSW, ideally incorporating the latest technologies in energy saving and generation.” "The recognition of the NSW Government of the need to provide a significant boost in apprentices is also a significant and critical step forward for the future. We encourage Government to extend these incentives to address the significant skills shortage and diversity of qualified professionals working in the infrastructure space. Both of these measures are essential legacy actions that should flow from the record $87.2B investment in infrastructure to keep NSW moving forward,” Mr Sharpe added.

ACA CORROSION FEATURE

An infrastructure asset base should be designed to be safe and reliable, while maintaining acceptable levels of service for the duration of the expected life of the asset. This requires asset owners and managers to develop and implement optimised approaches with often limited budgets. The balance of all these factors is even more important if the service life of an asset needs to be extended. Many governments and organisations that own and operate existing aging infrastructure are increasingly requiring it to exceed the original design life. If appropriate asset management strategies are implemented, it is possible to restore an asset to near its original condition and maintain its functionality for the remaining service life and, possibly, even beyond. As a consequence of restricted budgets, larger asset portfolios and increased pressure to extend asset life, many industries now recognise the importance of asset management processes for asset owners who need to balance risk, productivity and operation. A significant part of any asset base will suffer from corrosion to some degree, so the designed durability and corrosion management form part of, and support, good asset-management practices. The benefits of a well-developed asset-management plan include: a better understanding of the total asset base; an understanding of how assets with corrosion impact the operation and performance of the network; and making it clear when to intervene and address issues in order to avoid asset failure. When any asset is affected by corrosion, the damage can threaten its longevity and serviceability, which in turn may impact both its own functionality as well as that of other related infrastructure.

PRACTICAL MANAGEMENT OF CORRODED ASSETS The degradation of private and public assets and infrastructure continues to have a major economic impact on industry and the wider community. In Australia, the yearly cost of asset maintenance is estimated to be approximately $32 billion, with $8 billion attributed to avoidable corrosion damage, according to a report commissioned by NACE, the international body for professional corrosion engineers.[1] 54

Construction Engineering Australia â&#x20AC;˘ June/July 2018

ACA CORROSION FEATURE

Many years of experience at global consulting firm AECOM illustrate that a wide variety of asset-management strategies can be effective in the design and operation of assets affected by corrosion. In new assets for instance, considerations towards balancing development, construction and operational costs can yield optimal solutions for maintenance, safety, reliability and mitigation of corrosion risk during the required life of the asset. At the Australasian Corrosion Association's (ACA) Corrosion and Prevention 2017 conference and trade exhibition in Sydney, Sarah Furman, Associate Director in the Strategic Asset Management and Advanced Materials team at AECOM, presented a brief overview of managing assets with corrosion based on the company’s extensive experience. The ACA's annual conference is just one of the many ways the organisation collaborates with industry and academia to research all aspects of corrosion mitigation in order to provide an extensive knowledge base that supports best practice in corrosion management, with a view to ensuring that impacts of corrosion are responsibly managed, the environment is protected, public safety is enhanced and economies are improved. Understanding the relevance of corrosion’s impact on performance is critical for the development of an appropriate assetmanagement strategy for existing assets. Corrosion issues can lead to a decrease in the levels of service provided by the assets and plans allow asset owners the opportunity to optimise the extent and timing of future intervention and potentially mitigate some of the associated costs. The release of the international asset-management standard, ISO 55001 (2014), and other supporting guidelines, such as the International Infrastructure Management Manual (IIMM), provides consulting engineers and asset owners and managers

with guidance on the strategic whole-of-life management of an asset base, along with a number of processes, techniques and approaches that can be adopted to achieve this goal. According to Dr Frédéric Blin, who leads AECOM’s Strategic Asset Management and Advanced Materials team in Victoria, South Australia and Tasmania, the ISO 55000 series is an important standard, but its acceptance and use seems to vary across industry sectors and geographies. “More and more organisations are seeking to align themselves to the ISO 55000 series in Australia, but not necessarily be certified to meet it,” he said. “However, tram and train operators in the State of Victoria have to be certified to ISO 55001 standards.” “In Australia, the ISO 55000 series is seen as a representation of good practice and a useful benchmark point for organisations,” added Dr Torill Pape, Asset Management and Technical Specialist for Bridge Assets at AECOM. “The suite of ISO 55000 documents outline the ‘what and why’ for asset management, which is complemented by guidelines stipulating how to achieve the stated requirements at a strategic, tactical and operational level, such as the International Infrastructure Management Manual (IIMM),” Dr Pape continued. Discussions about the implementation and adoption of the standard have taken place at a variety of industry technical forums, such as the ACA conference. A durability plan, coupled with an asset register, provides an additional and useful baseline against which to monitor the condition and performance of the assets over time and thereby to tailor plans accordingly. It is a critical tool that supports an overarching asset-management strategy. The plan should clearly outline likely corrosion-related risks and agreed mitigation approaches as early as possible in an asset’s lifecycle - and ideally during the planning and design stage. In developing asset-management strategies for existing, ageing structures, the maintenance requirements need to be optimised between shortand long-term strategies in order to minimise the disruption to operations, while providing a safe and reliable asset. “While transport and public services rely on external advisory services such as consultants to supplement decision making,” Dr Pape added, “there is also a growing desire for a better in-house understanding of improved practices in asset management.” “To enable and demonstrate robust decision-making, asset owners welcome support and guidance from their advisors,” said Ms Furman. Deterioration modelling is another useful tool to support decision-making and asset-management processes. “This kind of simulation is usually numerical modelling that simulates conditions versus time,” said Ms Furman. “Modelling output can be used both in the design phase for projects yet to be built, as well as for existing structures.” “There is a lot of real world and site-specific data included in the models we create for deterioration modelling,” Ms Furman added.

“The accuracy of the models depends on the reliability of the input data, and good review protocols and data-auditing processes are needed to ensure the reliability and accuracy of the data.” “Modelling is just one tool in a suite used by engineers to inform them about an asset’s performance and to identify and develop cost-effective and risk-informed management strategies,” said Dr Pape. Decision-making processes are also improving with an increased focus on data analytics that supplement data collection and enable asset managers to develop informed maintenance and rehabilitation plans. “The technology landscape is rapidly changing as well,” Dr Blin said. “It is now possible to gather and store huge amounts of data, which requires data analysts to provide organisations with the insights that support optimised decision-making.” The ongoing impact of corrosion and its cost continue to be a major expense for government and industry, but organisations such as the ACA and AECOM continue to
