EDITOR’S COLUMN

The City of Adelaide in 1968. King William Street, Adelaide during the Festival of the Arts.

50 Years on

and still going strong! Dear Readers, This is issue represents an important milestone in the history of Highway Engineering Australia (HEA) magazine. It marks the beginning of our 50th Anniversary celebrations! And while it may be seen as some to be a little excessive (or maybe even a little selfindulgent) to celebrate across our entire 50th year, I, for one, believe it’s a milestone worth celebrating – especially given some of the challenges that we’ve had to overcome over the past 50 years – not only as a publication, but also as a 100% Australian family-owned business. Now, while achieving a 50-year milestone is not unique amongst publications, it is certainly not common. What’s more, the fact that HEA and the EPC Media Group have only ever had two owners – founders (my parents) Frank H. Schmidt & Adelaide Schmidt, and myself – makes it less common. The first issue of HEA magazine – which at that time was known as Highway Engineering in Australia, was published by my father in 1968, when I was 4 years old. Yes, that’s right… 4 years old (it’s actually quite an eye-opener just typing that sentence). As you can gather, I had very little to do with it at the time. However, after some 27 years with the Company, including over 16 years at the helm as MD/CEO, one thing is certain, starting a company and a new publication in a specialist field while trying to raise two young children in 1960s Adelaide was an extremely brave move on behalf of my father and mother, Adelaide Schmidt, who served as Company Director for EPC and Production Manager for HEA and later for it’s sister publications MEA and WWM until her retirement in 2002.

Australia in 1968 was very different to the Australia of 2018, and the road from then to now has not always been a smooth one (pun very much intended). Politically, 1968 started with the continuing search for missing Prime Minister Harold Holt who disappeared on December 17, 1967 whilst swimming near Portsea in Victoria – and the swearing in of John Gorton as Prime Minister on January 10. In State politics, 1968 saw Steele Hall defeat Don Dunstan to become premier of South Australia for two years until Don Dunstan’s re-election as Premier in 1970, while in Queensland, 1968 saw the appointment of Joh Bjelke-Petersen as Premier – a post he would hold until December 1987. From a cultural perspective, in many aspects Australia was not only a country divided, it was a country of staggering contrasts. Anti-Vietnam War protests and conscientious objection to conscription resulted in often violent clashes which rocked university campuses and city streets around the nation, while music and the arts in general continued to push back on the traditional conservative values that had largely dominated post-war Australia. Mind you, the Seekers and Johnny Farnham were as popular as the Beatles, the Rolling Stones and the Who, so it wasn’t all angry rebellion! From a roads and transport perspective, Australia’s love affair with the car was already in full swing - although our driving apparently left a lot to be desired! In 1968, our population was 12.1 million and there were a total of 4,279,000 registered motor vehicles on Australia’s roads. Alarmingly, despite this relatively low number of registered vehicles (compared to the 19+ million vehicles currently registered),

there was a staggering 3,382 road fatalities 1968 – representing 7.90 fatalities per 10,000 registered vehicles and 28.2 fatalities per 100,000 population. Truly horrible figures. 1968 also saw the completion of a number major project sections along many of Australia’s most iconic roads, including completion of the first stage of Sydney’s Warringah Freeway and sections of the Hume Highway in NSW; together with sections of the Federal Highway in the ACT, the Great Northern Highway in WA and the NT, the Eyre Highway in SA, Victoria’s Western Highway, the Brooker Highway in Tasmania and the Bruce Highway and Pacific Highway in Queensland. Interestingly, while researching this brief look back at 1968, it became clear to me that as far as we’ve come – especially in terms of road fatalities and road infrastructure, 2018 is still far from a perfect world. Few would question that there remains much to be done in terms of improving our road and transport networks, and most would agree that one road fatality is one too many. With that in mind, as long as there’s projects to be completed and road safety improvements to be made, our aim is for HEA to keep bringing you all of the details. Finally, I would like to take this opportunity to thank you all for your continued support and readership. After all, without you, the readers, HEA wouldn’t exist.

Research shows transport workers more likely to suffer injury on the job Transport workers are up to five times more likely to be injured at work than any other Australian worker, according to new Monash research, with rail drivers in particular 30 times more likely to develop a mental health condition than any other worker. These are just two of many significant findings unearthed in the first report of the National Transport Industry Health and Wellbeing Study, released recently by the Insurance Work and Health Group at Monash University.

The research, supported by Linfox Logistics and the Transport Workers Union, comes from the first stage of a detailed national study looking into the health of workers in the transport industry. The Australian transport and logistic industry is very diverse, and encompasses drivers, logistics, storage and warehousing workers, managers and executives. Alex Collie, professor and director of the Insurance Work and Health Group, said transport workers were subject to a unique set of health risks in their working environment, including sedentary jobs, long working hours and shift work, isolation, fatigue and sleep deprivation, among others. "This study presents a national picture of the health of people working in the transport and logistics industry. Prior studies have focused on safety and on specific groups of workers. We used a large and detailed national database of work injury claims to examine a range of different injuries and diseases that affect workers across the whole industry,” Professor Collie said. "Our ultimate aim is to develop programs and services that can prevent illness and injury in the transport sector, and help people recover and return to work when they become sick." There are strong links between people’s health and their ability to work, Professor Collie said, so understanding and improving the health of an industry which employs 1.2 million people is important for the workers, their employers and the Australian economy. The Transport Workers Union national assistant secretary, Michael Kaine, said the report’s findings show that the “pressures on transport workers, including long hours away from family, chronic fatigue and the stresses of meeting deadlines, are clearly taking their toll”. “It should serve as yet another example of the need for a check on the transport supply chain, to ensure that the major clients at the top are being held to account for the pressure they exert on the industry and its workforce,” he said. Linfox Logistics General Manager of HR Lauren Pemberton said working with Monash and TWU to investigate driver health and safety was the “next logical step in improving our staff health programs.”

Meeting Queensland’s major project pipeline funding challenges Daily commute gets longer, and most prefer the car Fewer commuters are working in the same area as they live, and most continue to drive to work rather than use public transport, according to a study based on the 2016 Australian census. University of Queensland population geographer Professor Jonathan Corcoran said the proportion of Australian workers who lived and worked in the same geographical areas – referred to as “selfcontainment” – had decreased since 2011. This had important social, economic and environmental consequences. Professor Corcoran, of the Queensland Centre for Population Research in UQ’s School of Earth and Environmental Sciences, said Adelaide, the Australian Capital Territory and Sydney reported the largest declines in selfcontainment, with Darwin returning a small increase in commuters living close to their workplace. “In Sydney’s inner west, just 26 per cent of respondents lived and worked in the same area. “In Melbourne’s inner east it was 35 per cent, and there were comparatively low rates of selfcontainment in Brisbane’s west (31 per cent), Adelaide’s west (49 per cent) and Perth’s north east (41 per cent),” he said. “For 60 per cent of employed Australians, work was reported to be in the same labour market region as their residence, and most still used private vehicles to get there.” Of the 9.2 million commuters on Census day, 79 per cent travelled to work by private vehicle, 14 per cent took public transport and 5.2 per cent cycled or walked. Of Australia’s 10.7 million employed, just five per cent worked from home. Professor Corcoran said the strong preference for driving to work echoed similar patterns in other Organisation for Economic Co-operation and Development nations, and the proportions had changed little since 2011. The only exceptions were in New South Wales and Victoria, where public transport use had increased and car use declined slightly. The study: Journey to Work in Australia, by Jim Cooper and Professor Jonathan Corcoran, was been released recently by the Australian Bureau of Statistics.

Industry leaders call for sustained focus on finding and developing solid infrastructure projects to maintain momentum and secure State’s future. Three of Queensland’s leading industry bodies recently released their key annual report, calling for greater collaboration from State and Federal Governments to lead the charge in funding and accelerating infrastructure projects throughout Queensland in a bid to maintain the state’s current economic momentum. The 2018 Queensland Major Projects Pipeline - a report developed by leading independent firm BIS-Oxford Economics for the Queensland Major Contractors Association (QMCA), the Infrastructure Association of Queensland (IAQ) and Construction Skills Queensland (CSQ), details a pipeline of 190 projects with combined expenditure of $39.9 billion over five years and identifies 14 separate initiatives that governments can adopt to boost their funding capability and deliver the infrastructure Queensland requires. The report identifies the greatest threats to a sustainable pipeline of projects are the identification of investable projects, availability of funds and timely investment decisions. This year’s report highlights much lower levels of private sector investment than previous years, with $9.4 billion of expenditure only ‘prospective’ or ‘unlikely’ to receive funding in the next five years. According to QMCA’s President Peter Anusas, the value of committed public sector projects entering the market for tender by contractors now outstrips the private sector by a factor of 6:1, fuelled by projects such as Cross River Rail, Bruce and Pacific Highway upgrades and the upcoming ARTC Inland Rail PPP package. “Whilst the level of public sector investment identified in the report is positive news, there are significant opportunities for project savings and more jobs if some projects identified to start later in the pipeline can be brought forward to flatten out the demand curve,” Mr. Anusas said. According to Mr. Anusas, there are still a significant amount of public and private projects (98) that are awaiting funding commitments. The funded pipeline for major projects in Queensland is forecast to support 12,700 workers each year on average

throughout the state and this increases to an additional 4,700 workers each year on average if the pipeline is fully funded. “Many of these construction jobs can make a real difference to regional communities who are struggling to adjust after the resources boom,” said Mr. Anusas. IAQ’s Chief Executive Officer Steve Abson said accelerating government projects through the pipeline required even greater collaboration between the Australian and State Governments. “With low levels of privately funded projects coming through to market, the ability of governments to identify and deliver on their planned infrastructure is really important to the sector,” said Mr. Abson. About Queensland Major Contractors Association (QMCA) The QMCA is the construction industry peak body representing Queensland’s leading construction contracting companies and is dedicated to making the construction industry safer, more efficient, more competitive and better able to contribute to the development of Queensland and Australia. QMCA’s current membership includes the top-performing construction companies in Queensland, which together account for approximately 70-80% of the construction and civil engineering work in the State.

New changes for the transport of dangerous goods The Australian Code for the Transport of Dangerous Goods by Road and Rail is set to be updated with changes designed to reduce the burden on industry when transporting low-risk items and bring into line with new United Nations transport requirements. In May, Transport ministers approved version 7.6 of the Code, with the changes effective from 1 July 2018 and compulsory from 1 July 2019. National Transport Commission Chief Executive Paul Retter said one of the key changes included simplifying transport of lower-risk limited quantities of dangerous goods. “Operators who transport low-risk dangerous goods in limited quantities such as household cleaning products, perfumes and cosmetics will no longer be compelled to abide by overly burdensome labelling and marking requirements, for example,” Mr Retter said. Every two years, the United Nations updates the Transport of Dangerous Goods Model Regulations. The United Nations recently approved the 20th round of changes to the United National model regulations. These model regulations are subsequently adopted by participating countries. “The changes approved by ministers on 18 May 2018 will ensure the Code aligns more closely with United Nations Regulations,” Mr Retter said. Other changes include exempting mobile processing units (MPUs) from the Code to remove duplicate requirements in other laws, as long as the MPU is authorised within each jurisdiction to operate. MPUs are vehicles designed to take raw explosive materials to mine sites where the explosive will be manufactured and used.

8 Highway Engineering Australia | June/July 2018

States and territories have committed to amending their local laws to align with making the changes from version 7.6 of the Code for the Transport of Dangerous Goods by Road and Rail to their local laws. The National Transport Commission is responsible for the maintenance of the model legislation for the land transport of dangerous goods in Australia. Version 7.6 of the Code will be available on the NTC website in the coming weeks.

Monash University welcomes commitment on heavy rail linking Caulfield and Clayton Monash University has welcomed the Federal Government’s recent Budget announcement of $475 million to build a rail line linking the Caulfield and Clayton campuses. The much-needed rail link between the Caulfield Station and Clayton Campus will significantly enhance travel options for the tens of thousands of students, staff, industry partners and visitors who travel to Monash each day. The project will not only support the country’s largest education provider, but also the surrounding innovation precinct. The

Monash Precinct is the largest employment hub outside of Melbourne CBD and provides significant employment and economic benefits to the entire country. President and Vice-Chancellor, Professor Margaret Gardner AO said the announcement was very welcome recognition by Federal Government of the importance of Monash and the South Eastern corridor to Australia’s continued innovation and economic growth. “Our Clayton campus can attract more than 53,000 people daily, the equivalent population of a major regional city. Fast, efficient and effective public transport links will reduce road congestion and deliver benefits to the wider innovation precinct,” Professor Gardner said. “Reducing car use is core to Monash University’s sustainability effort. We know that many who drive to campus would use public transport if more convenient options were available.” Monash is committed to supporting all levels of government to encourage the improvement of public transport options at each of the University’s campuses. Recently, Monash worked with the Victorian State Government on the upgrade of Huntingdale Station and has completely redesigned the bus interchange on the Clayton campus to make it easier, faster and safer to access the campus via public transport. The heavy rail link announcement followed a visit by Minister for Urban Infrastructure and Cities, the Hon Paul Fletcher MP, to the Clayton campus where he saw firsthand the pressing need for investment in a mass transport solution to service the University and broader Monash Precinct. “We are very pleased the rail link has been identified as a priority. A very sizable proportion of South East Melbourne stands to benefit from this extension and it is wonderful to see it included in this year’s Federal Budget. My thanks to Minister Fletcher for his recognition and support for this transformative initiative,” Professor Gardner said.

PBS changes will encourage further innovation in heavy vehicle industry Australia’s transport ministers have approved National Transport Commission (NTC) recommendations to improve the PerformanceBased Standards (PBS) scheme and encourage investment in a greater number of safer, efficient heavy vehicles on Australian roads. “PBS scheme vehicles offer between 15 and 30 per cent more productivity than conventional heavy vehicles, depending on the freight being carried. This means the same freight task can be delivered with fewer vehicles on our roads and the flow-on effects include reductions in fuel consumption, carbon emissions and road maintenance costs,” said NTC Chief Executive, Paul Retter. “However, our review of the PBS scheme has revealed that the take up of the scheme has not been as strong as it could be because of issues such as barriers to access, leading to a reluctance from industry to participate.” Mr Retter said that the NTC has made several recommendations to address these barriers and, as a result, encourage further adoption of the scheme to ensure the original safety, productivity and environmental objectives can be reached. The key recommendation from the review was for states and territories to allow as-of-right access for PBS certified vehicles to operate on PBS declared road networks. This will address one of the main barriers to the scheme by substantially improving the infrastructure access approval process for PBS approved vehicles. Other recommendations approved by ministers include: • Austroads to design nationally consistent guidelines for road managers to assess infrastructure, including pavement and bridges • National Heavy Vehicle Regulator (NHVR) to review the PBS standards (the requirements for a vehicle to participate in the PBS scheme) to ensure they reflect the latest in vehicle technology and design and as a result improve the safety performance of the PBS fleet. • The current PBS standards were developed in the late 1990s and technology has improved to a level where compliance against a number of these standards can now be achieved through alternative solutions such as anti-lock braking system (ABS) / electronic braking system (EBS) and roll-over protection that meets the stability and braking requirements. • NHVR to develop and lead the development of a communications plan to further promote the benefits of the PBS. “Despite the current scheme’s limitations, the review found evidence that it has still delivered significant benefits, including savings of an estimated 94 million litres of fuel in 2016, which in turn reduced carbon emissions by about 250,000 tonnes,” said Mr Retter. “There are currently around 16,000 separate PBS registered trucks, trailers and buses which address some of the unique freight and environmental challenges we face in Australia, and we hope that these changes will allow the scheme to continue to grow.”

Federal Minister for Urban Infrastructure and Cities Paul Fletcher said today’s announcement is a major milestone for WestConnex. “This is the crucial final piece of this transformational infrastructure project. WestConnex is delivering a skills legacy, with more than 10,000 direct and indirect jobs created over the life of the project,” Mr Fletcher said. “This will mean a quicker, safer and more reliable journey for commuters and 10,000 fewer trucks on Parramatta Road east of Concord.” WestConnex Minister Stuart Ayres said: “This is a significant day for a project that will help thousands of motorists everyday by easing congestion on M4, M5 and Parramatta Road.” “The M4-M5 Link is the most important stage of WestConnex, providing a vital connection between two of Sydney’s busiest motorways. We are linking the New M4 at Haberfield with the New M5 at St Peters, creating a western bypass of the CBD.” CEO of Engineering and Services at Lendlease Craig Laslett said: “The M4-M5 Link is a critical project that will drive Sydney’s economic growth and deliver new jobs and training opportunities.” CEO of Samsung C&T Corporation Youngho Lee said: “It is a privilege to continue to work with the NSW Government to deliver this crucial project, increasing local training opportunities and employment whilst addressing Sydney’s future transport needs.” Work on the M4-M5 link will get underway later this year.

COMPANY PROFILE

TITAN’S ‘ONE STOP SHOP’ DELIVERS MAJOR BENEFITS FOR TRUCK AND 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 to 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 fleet and equipment owners across Australia. Adam Oakenful, Chief Operating Officer with Titan Australia, explained: “In the roads and infrastructure construction and maintenance sector, the majority of operators tend to have an extremely diverse fleet of vehicles and equipment.” “From small trucks, 4WDs, tippers and low-loaders, through to excavators, dozers, graders and other construction equipment (both large and small), the range of tyres, wheels, track and undercarriage components

10 Highway Engineering Australia | June/July 2018

required to keep these fleets on the road or 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.” 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.

EXPERIENCE MATTERS

ROADTEC MTV1100E WHEELED AND MTV1105E RUBBER TRACKED MATERIAL TRANSFER VEHICLES Roadtecâ&#x20AC;&#x2122;s MTV mixing technology is engineered to deliver superior results, with high performance material handling that makes it easier for the crew to deliver a high quality, consistent final product.

12 Highway Engineering Australia | June/July 2018

COVER STORY

Hydraulically operated clean-out doors are located at each conveyor. Maintenance items such as grease points, fluid-fills, the main electrical box and DEF tank can be accessed from the ground and do not require personnel to open the hood or crawl under the machine on the ground for regular checks. The machines feature a 2,971mm transport width and an operating length of 12,446mm. The MTV-1100ex and MTV1105ex feature a frame that is fabricated, welded and assembled by Roadtec at their Chattanooga, Tennessee USA Factory.

The trusted Roadtec brand continues to lead the industry as an innovator in material transfer vehicles. It has long been proven and accepted that the remixing and storage/dwell time features provided by Roadtec’s SB2500 and SB1500 solve the haulage associated problems of mix segregation and temperature differentiation. Roadtec’s ability to present a mix to the paver that is homogenous and even in temperature, improves compaction results and surface evenness. However, for those jobs where material storage and dwell time is not required or impractical, the Roadtec Material Transfer Vehicle (MTV) 1100ex (Wheeled Unit) and 1105ex (Rubber Tracked Unit) provide ideal choices to enhance laying results.

Key Features, Benefits and Associated Value APPLICATION Simply put, the MTV 1100ex and 1105ex are Roadtec (Shuttle Buggy) SB1500/2500s without the storage hopper and internal remixing capabilities. Their compact design makes them an ideal solution for situations where material storage is not practical – such as tunnels or other extremely congested work areas.

HOW DOES THE MTV WORK Roadtec’s high performance material handling and re-mixing technology is globally renown. Having proven its success for over thirty years, this technology makes it substantially easier for laying crews to deliver superior compaction and rideability results. As the name implies, the MTV 1100ex and 1105ex are vehicles which transfer material (asphalt) from the delivery truck to the

paver. In doing so, the MTV eliminates the need for the delivery truck to unload directly into the paver. Consequently, there is no contact by the truck with the paver. This allows for non-stop paving, which in turn, results in a smoother surface finish. The machine design features antisegregation mixing technology to keep the material in an optimised, uniform condition throughout the transfer process. A high level of mixing and segregation correction is achieved by placing the focus in the dump hopper, where the machine has the largest volume of mix to process. The dump hopper has a generous capacity and includes a uniquely designed 500tph Triple Pitch auger system like the SB1500 and SB2500. At 560mm in diameter, the Triple Pitch Augers are designed to move material more efficiently and reduce segregation, with the added benefit of reduced maintenance costs. These unique augers continuously remix the asphalt, blending the coarser material with the finer material to produce a more homogenous mix. Driven by a 250hp Cummins QSB 6.7 engine, the MTV 1100ex and 1105ex have ample power to drive the 500tph auger system for the receiving and unloading of material. As well as pushing the delivery vehicles, the dump hopper is designed to allow trucks to unload efficiently. A vibrating bottom plate in the hopper is designed to prevent material build-up, while the heavyduty, swivelling support casters under the hopper are designed to provide smooth movement. The dump hopper is controlled from the main operator platform. The unloading conveyor slews to 55 degrees either side, allowing material to be transferred across lanes.

VISIBILITY AND ACCESS Designed with a low 2m deck height, the Roadtec MTV1100ex and MTV1105ex are designed to keep the operator closer to the ground. Operating from an ergonomic seat with controls at the armrest, the operator has a clear view of the surroundings and can communicate easily with the delivery drivers and those on the ground. Dual (Patent pending) staircases with handrails flank the machine, allowing ground workers to cross the paving train without the risk of walking between machines.

SERVICE SUPPORT Astec Australia is a sister company of Roadtec and live by their core value of ‘continuous devotion to meeting the needs of the customer’. With service and parts centres in Melbourne, Perth and Brisbane and a dedicated service agency in Sydney, support is always at hand.

COVER STORY

MTV-1100E Wheeled Material Transfer Vehicle The MTV-1100e non-storage material transfer vehicle has been designed from the ground up with contractors and job performance in mind.

The machine gets the operator closer to the crew and in a position to operate the machine and dump trucks. This also provides an opportunity to eliminate the

need for a ‘dump-man’ – which can be one of the most at-risk positions on a jobsite. These benefits, combined with Roadtec's world-renowned material transferring capabilities delivers outstanding productivity. HMA is moved to the hopper insert without contacting the paver, allowing for non-stop paving on long pulls for the highest quality result.

MTV-1105E Rubber Tracked Material Transfer Vehicle The rubber track MTV-1105e transfers asphalt material from a truck to a paver for noncontact paving.

With tracks made for any environment, you never have to worry about the jobsite base. If the ground is solid enough for paving, the MTV-1105e smoothly and effortlessly carries material anywhere you need. An all new operator station gives exceptional visibility from the dump hopper across the low-profile design back to the paver. This position allows the option of the main operator signaling truck dumps while leading the paver.

EZY-GUARD HC INSTALLATION ON THE TOOWOOMBA SECOND RANGE CROSSING PROJECT Ingal Civil Products ‘Ezy-Guard HC’ (High Containment) guardrail barriers will be ensuring the safety of millions of motorists when the Toowoomba Second Range Crossing (TSRC) opens in 2019. The TSRC is a 41 kilometre heavy vehicle bypass route to the north of Toowoomba, jointly funded by the Australian and Queensland Governments. Construction started in April 2016 by the joint venture Nexus Delivery with a price tag of $1.6 billion, and is the largest Australian Government commitment to a single road project in Queensland’s history.

A total of 66 kilometres of Ezy-Guard HC was supplied for installation on various sections of the TSRC and was chosen due to its high containment capacity and full compliance with MASH TL4 crash tests, proving to be a suitable system for the TSRC requirements. The new bypass will improve freight efficiencies and provide a safer, less congested route than the existing range crossing. When complete, it will enhance livability and amenity for residents by removing heavy vehicles from Toowoomba’s CBD and reduce travel time across the

Toowoomba Range by up to 40 minutes by eliminating up to 18 sets of traffic lights for heavy commercial vehicles. Being able to properly withstand and yield to a crash of a 10,000kg truck travelling at 90km/h impacting at 15 degrees, Ingal Civil represents the next generation of safety barrier systems. Its design allows soft-ride down decelerations of heavy impacting vehicles and uses fewer components, providing rapid installation and repair. The Ezy-Guard HC is 100% locally designed and produced, proving to be the ideal choice for a project of national significance and a sound investment in the lives of Australian motorists.

ROAD SAFETY

FIRST AFRICAN OBSERVATORY TO TACKLE THE CONTINENT'S ROAD SAFETY CRISIS The World Bank, the Fédération Internationale de l’Automobile (FIA), and the International Transport Forum (ITF) recently signed a Memorandum of Understanding (MoU) to establish the first regional Road Safety Observatory in Africa. The Observatory will support African countries’ efforts to reduce road transport fatalities by uniting their activities to systematically collect, analyse, and share reliable road crash data. It will also serve as a platform for government officials and road safety experts to exchange knowledge, share best practices, and scale up effective policies across the region. Improving road safety has emerged as a top development priority for Africa, which has seen the highest rate of road traffic fatalities in the world despite comparatively low levels of motorisation. By providing more comprehensive and accurate data, the new Observatory will help gain better insight into the key risk factors contributing to the region’s road safety crisis, and will give African countries the resources they need to design evidence-based strategies and interventions. UN Secretary General's Special Envoy for Road Safety and FIA President, Jean Todt, said, “By understanding the root causes of traffic injuries and fatalities, policy makers can better evaluate the preventive measures available and make investment in road safety more effective. It is my hope that this joint initiative can create a platform for knowledge sharing amongst African countries.” José Luis Irigoyen, World Bank Senior Director for Transport and Digital Development, stated, “The World Bank is

20 Highway Engineering Australia | June/July 2018

proud to be a part of this initiative. We are confident that the new Observatory will increase the visibility of the road safety challenge in Africa, enable governments to advance regional collaboration, and leverage synergies among African nations to improve road safety conditions, as the Road Safety Observatory in Latin America (OISEVI) is already doing.” ITF Secretary-General, Young Tae Kim, said on the occasion of the MoU signing: “Africa has 2% of the world’s cars but 20% of the road deaths. The continent must be empowered to tackle this problem now. Supporting governments in the region to collect, analyse and use quality crash data is a powerful way to direct scarce resources to their most effective use and save more lives.” The MoU signing was attended by Morocco’s Vice-Minister of Transport, Mr. Mohamed Najib Boulif, whose country has offered to host the Observatory. The launch of the Observatory was announced on the opening day of the International Transport Forum’s Summit— the world’s largest gathering of transport ministers and policy makers - which this year focuses specifically on transport safety and security. The MoU follows a resolution signed in February by Benin, Kenya, Morocco, Nigeria, Senegal, South Africa, and Tanzania, confirming their interest in the project. These seven African countries are currently working on finalising the Observatory’s governance structure and funding mechanism. This initiative benefited from the support of the Africa Transport Policy Program (SSATP), the World Health

Organization (WHO), the Global Road Safety Facility (GRSF), the United Nations Economic Commission for Africa (UNECA), the Islamic Development Bank (IDP), Safer Africa and others.

ABOUT THE WORLD BANK GLOBAL ROAD SAFETY FACILITY (GRSF) The World Bank Group plays a key role in the global effort to end extreme poverty and boost shared prosperity. Reducing road traffic injuries and deaths is at the core of supporting this agenda and realising the development of human capital. In 2006, the World Bank established the Global Road Safety Facility (GRSF) funded by external donors to address the growing road safety crisis. The Facility works with international partners to provide funding and technical assistance to scale up low- and middle-income countries’ capacity to implement cost-effective road safety programs.

ROAD SAFETY

New heavy vehicle brake standards will save lives Heavy vehicle operators and other road users will soon be safer on the roads following new Australian Design Rules (ADRs) aimed at reducing heavy vehicle rollovers and similar loss-of-control crashes. The ADRs will mandate Electronic Stability Control (ESC) for new heavy vehicle trailers from July 2019 and for selected new heavy trucks and buses from November 2020. This will bring the same life-saving technology to Australia as is currently required in Europe, the US and other markets. More than 200 people are killed on Australian roads each year as a result of fatal crashes involving heavy trucks or buses. Approximately 20 per cent of those tragic deaths can be linked to rollovers or loss of control, so by having advanced braking systems fitted we can save an estimated 126 lives and reduce the number of serious injuries by more than 1,000 over the period of regulation. These changes will greatly improve safety for all motorists and reduce the impact of road trauma on Australian communities by an estimated $216 million. Heavy vehicles typically have large masses, long length and relatively long stopping distances when compared to light vehicles, thereby increasing both the risk and severity of crashes involving heavy vehicles. Many heavy truck and bus rollovers involve only one vehicle and fitting ESC will, in many cases, prevent these kinds of crashes occurring. Feedback from industry and road agencies to a Regulation Impact Statement released earlier this year indicated broad support for the introduction of new ADRs for ESC and related Roll Stability Control (RSC) systems.

22 Highway Engineering Australia | June/July 2018

Industry and governments have been active in encouraging, or requiring the use of advanced braking systems such as ESC, Antilock Brake Systems (ABS), Electronic Braking Systems (EBS) and RSC in heavy vehicles. Peak industry bodies have also worked in partnership with the Commonwealth to minimise the regulatory costs, including by harmonising the ADR as much as possible with other major markets around the world. Consideration of ESC was an agreed action under action item 16(c) of the National Road Safety Strategy 2011-2020 and action item 8 of the National Road Safety Action Plan 2015-2017. Heavy vehicles represent three per cent of registered Australian vehicles and account for just over eight per cent of total vehicle kilometres travelled on public roads, but on average, they are involved in close to 17 per cent of fatal crashes. The new ADRs can be found on the Federal Register of Legislation at: www.legislation.gov. au/Details/F2018L00664 (ADR 35/06) and www.legislation.gov.au/Details/F2018L00692 (ADR 38/05), including the final Regulation Impact Statement (RIS) (https://www. legislation.gov.au/Details/F2018L00664/ Download). An overview of the new requirements and changes to the ADRs can be found in Appendix 11 of the RIS.

Public consultation begins on further motorcycle safety reforms in WA Western Australian Acting Road Safety Commissioner Iain Cameron has encouraged the public to have their say on the future of motorcycle safety in WA.

The WA State Government recently released its Motorcycle Safety Reforms Consultation Paper. “Motorcyclists are amongst our most vulnerable road users, and the Road Safety Commission is seeking responses to a range of suggestions to improve motorcycling safety,” Mr Cameron said. Mr Cameron said the consultation paper was accompanied by a survey that asks for comment on the following proposed reforms: • Amendments to the Road Traffic Code 2000, to provide clarity regarding the practices of motorcycle lane filtering and splitting; and • Enhancing the current licensing and testing requirements for motorcycles and mopeds by including: • a minimum learner’s permit tenure period; • a pre-licence motorcycle specific Hazard Perception Test (HPT); • a minimum two-year restricted licence (LAMS) phase on R-E class motorcycles; and • increasing the rigour of the two motorcycle PDA (for R-E class and R class vehicles). Assessments for R class vehicles to be more rigorous than that of R -E class vehicles, reflecting the higher order skills required for a more powerful motorcycle. “The number of people in Western Australia choosing to use a motorcycle as their means of transport has more than doubled since 2008, more than any other state,” said Mr Cameron. “Motorcycle riders continue to be overrepresented in serious crashes on our roads, and these proposed reforms are aimed at improving their safety.” You can read the Motorcycle Safety Reforms Consultation Paper on the Road Safety Commission website at www.rsc. wa.gov.au/Motorcycle-Safety-Survey

SPECIAL REPORT

Zoe with C-ITS in-vehicle devices at the ‘Smart Highways’ Project, south of Seoul

Future connections strong after South Korea exchange What will the transport network look like in the future? This is one of the questions Zoe Eather, Project Engineer for Queensland’s Department of Transport and Main Roads, carried with her on a three-month exchange to South Korea late last year. A joint initiative between the department and Trade and Investment Queensland, the exchange program was designed to reinforce long-term professional links between Queensland and South Korea, and encourage collaboration on future technologies in the fields of engineering and transport infrastructure.

So why South Korea? “South Korea is a special mix,” says Zoe. “With high rates of urbanisation and technological know-how, the country offers a unique insight into how we might tackle the transport problems of tomorrow using ‘smart’ technology.”

24 Highway Engineering Australia | June/July 2018

“South Korea aims to be a ‘Smart Nation’ by 2025, and is currently undertaking a number of projects across the country to test new technologies in the transport and infrastructure space.” Some of these technologies, like Automated Vehicles and Cooperative ITS (intelligent transport systems), align with what Transport and Main Roads is already working on in Queensland, offering strong opportunities for collaboration.

Automated Vehicles One of Zoe’s first stops in South Korea was Gyeonggi Province, just outside Seoul, where she met with the Autonomous Driving Laboratory team from Advanced Institutes of Convergence Technology (AICT). Later this year the team expects to open the first stage of its Cooperative Autonomous Vehicle test bed in “Pangyo Zero City”, a ‘technology eco-system’ that will see the convergence of autonomous

SPECIAL REPORT

relationships with interested parties for all over the world. One of the aims of the project is to prepare a transportation system for South Korea’s aging population, which is a significant concern for the country. But the technology is also expected to realise a 70% reduction in traffic accidents by cutting back on driver error and dangerous driving. Transport and Main Roads is set to kick off a similar test bed initiative in the City of Ipswich (40 kilometres west of Brisbane) from 2019. Dennis Walsh, General Manager for Land Transport Safety (Transport and Main Roads), says the Ipswich project will prepare Queensland roads for advanced vehicle technologies, and ultimately accelerate their introduction. “Our four-year pilot is one of the largest of its type in Australia and will see our department work with a wide range of industries to adapt existing traffic systems, infrastructure and data,” says Dennis. “Pangyo Zero City is interesting to us for a number of reasons, but in particular because they are inviting Automated Vehicle teams from around the world to participate in the project - opening the way for all kinds of compatibility issues that could be interesting to learn from. “Zoe’s meeting with the project team has opened the way for us to learn a lot from their experience, and I believe we can offer a lot from our experience in return.”

Research Insights for C-ITS Zoe’s visit to the Smart Highways Project, south of Seoul, provided more useful insights

for Transport and Main Roads’ research into Cooperative ITS (C-ITS). After an initial “Smart Highways” 11km test bed pilot, the South Korean government is currently undertaking a national C-ITS Project from Sejong to Daejon which will see 88km of highway equipped with panoramic cameras, radar sensors and wireless base stations, designed to detect and transmit safety information to highway users. The system will use WAVE, a wireless technology, to transmit information to drivers in real time, warning them of unexpected situations on the road ahead, such as accidents, bad weather or debris on the road. The project again finds a parallel in Transport and Main Roads’ Ipswich test bed, where hundreds of motorists will take part in a Cooperative ITS project. 500 Ipswich motorists will have their vehicles retrofitted with C-ITS technology, which will detect and warn drivers about everything from pedestrians to red light runners.

What’s next for Zoe? “My three months in South Korea was such a fantastic experience. I’m really excited about sharing what I’ve learned over there, and also helping to facilitate greater collaboration between our two countries,” says Zoe. “I think the future is bright, and by sharing knowledge on a global scale we can only get there faster,” she added. Zoe Eather has taken up a new position on her return to Queensland in the Department of Transport and Main Roads’ Cooperative and Autonomous Vehicles Initiative team.

INFORMATION TECHNOLOGY

How technology will power investment in construction by Tom Karemacher, Vice President of APAC, Procore The recent federal budget included an almost $8 billion investment into roads and railway lines for Victoria, as well as a $1 billion Urban Congestion Fund. These investments follow various headlines around budget blowouts and schedule changes to significant infrastructure projects across Australia, including the recent $1.2 billion budget blowout for the NSW light-rail project. With the ongoing need for more and renewed infrastructure nationwide, alongside the challenges the construction industry is facing with keeping projects on budget and on schedule. There needs to be a review of how the tools, technology, and processes in place are being used by the teams on the ground. When planning or managing a major infrastructure project, it is critical to assess the needs and processes of the project from day one. There has to be an evaluation of the tools and technologies that are required to ensure the project succeeds. This requires a long-term view, as infrastructure projects such as roads and railways, can take years to complete. Also of consideration, is the completion date and the possibility that the needs of the communities may have changed.

How technology can enable budget and schedule management While construction is the third least digitised sector in the world, demand for the right technology to support major construction projects in Australia has never been higher.

26 Highway Engineering Australia | June/July 2018

Historically, technology vendors have been slow to adapt to the fast-changing needs of the construction sector, yet we are now at a stage where the technology is available and needs to be used wisely. A common challenge with large construction projects that leads to requiring excess costs and time, is the need for re-work – i.e. completely re-doing tasks onsite due to the work being done based on incorrect or inaccurate data. Consequently, when construction companies and governments look to tackle the major projects they have ahead, it will be critical to leverage technology that enables: • Real-time information sharing: Rather than risk on-site teams working off old blueprints or documentation, the technology and tools are now available to enable on-site workers to take photos on their phones or tablets of issues on a project, and immediately share those images with back office teams to ensuring nothing falls through the cracks. Simultaneously, if there are changes to a plan, back office teams can immediately inform on-site workers as those changes happen. • Easy data and documentation sharing: Traditional pen and paper documenting of construction jobs cannot continue, considering the scale and complexity of projects happening today. The risks of human error, misreading someone’s handwriting, or simply losing the physical

paperwork are not worth it. Having an easily accessible online platform to share and store all documentation in one place will ensure on-site workers aren’t spending excess time – nor the government’s budget – on looking for information. • Access to historical data: Knowing how, when and where a task was completed in the past, can significantly help construction and project teams find efficiencies. This can also play a major role in improving on-site safety. Technology can offer an easy and accessible way for workers to document potential hazards to the whole team in real-time. Also, powerful insights can be drawn from previous accidents such as common times, places or even weather conditions where accidents occur. Project and site managers can then use these insights to proactively prevent further accidents. Though the construction projects ahead may seem daunting and there are significant challenges the government needs to overcome, considering past budget and scheduling errors, there is a significant opportunity today to use technology effectively to save on time, resources, and on-site injuries. By tapping into these capabilities, technology can empower the construction industry to do more with less, and drive even further investment across the sector to support the growing population in Australia’s major cities and the need for reliable infrastructure nationwide.

DELIVERING OUTSTANDING PERFORMANCE AND VALUE AUSTRALIAN 2 YEAR IN-SERVICE PERFORMANCE REPORT Smart Cushion Replacement Parts Costs

Durability and Robustness

• 3 main types of components were replaced over the 59 resets

• 31 different Smart Cushion units required 1 or more resets

• Shear Pins (2 x $2 = $4) required for every reset

• 8 Smart Cushions were reset twice

• Delineator Panel ($190) required for 21 resets

• 1 Smart Cushion was reset 5 times

• Sled Panel ($1416) required for 4 resets • The total cost of replacement parts over the 59 resets was $9,994 • The average cost for each reset was $169

• 2 Smart Cushions were reset 4 times • 1 Smart Cushion was reset 11 times • Average Reset Time 55 Minutes (1 person crew) • All Smart Cushions were reset ﬁt for service after an impact

THE ONLY STRUCTURAL COMPONENTS REQUIRING REPLACEMENT IN OVER 90% OF IMPACTS ARE 2 X ¼” SHEAR BOLTS (COST < $5)

SMART CUSHION INNOVATIVE DESIGN AT ITS BEST

Renowned for its remarkable performance in the field - both in terms of its impact energy absorbing capabilities and the speed and ease with which the unit can be reset following an impact - SMART CUSHION is also being lauded by governments, road authorities, contractors and infrastructure owners alike for the significant reduction in post-impact repair and reinstatement costs that it offers when compared to other traditional impact barrier systems. Tested and approved to the US MASH TL3 standard, the key to SMART CUSHION’s remarkable performance lies within its unique design, which incorporates methodologies to dissipate energy both by mechanical and by hydraulic means. Specifically developed to maximize both safety and reusability, SMART CUSHION’s fully redirective, non-gating, bi-directional, design delivers outstanding performance and durability before, during and after an impact. Unlike the old-style attenuators, the SMART CUSHION attenuator rarely reaches maximum stopping resistance due to the interactive feedback nature of the system. It is this continuous interactive feedback system that allows the lowest ride-down accelerations when impacted end-on.

THE SMART MONEY IN ROAD SAFETY IS ON SMART CUSHION Low initial cost does not always equate to getting a good return on the investment. This is particularly true for impact protection systems, which by their very nature, are extremely likely to require repairs and/or replacement parts following a vehicular impact. Put simply, what may appear at the outset to be a ‘better value’ solution can, in fact, end up being an extremely expensive selection, with repair costs quickly adding up to multiples of the initial purchase price. If every impact results in a majority or even total replacement of the unit, perceived savings can soon disappear – and the costs will continue to escalate… year after year! SMART CUSHION has set a new benchmark in what road safety experts regard as 'good value' in crash cushion selection. Together with the signiﬁcant reduction in labour and trafﬁc management costs offered by SMART CUSHION following an impact, the fact that in over 90% of impacts the only structural components requiring replacement are 2 x ¼” Shear Bolts (costing less than $5), when it comes to whole-of-life costs, SMART CUSHION truly is in a league of its own!

TCA NEWS

TCA WORKING ON INTEROPERABILITY OF FATIGUE MONITORING DEVICES Transport Certification Australia (TCA) has announced that it is leading work to facilitate the interoperability of fatigue monitoring devices and telematics In-Vehicle Units (IVUs). Fatigue monitoring devices, which broadly include systems and services which detect driver drowsiness, are being adopted across the heavy vehicle industry to proactively manage driver fatigue. The A/Chief Executive Officer of TCA, Paul Corkill, said, “It may surprise many that these devices communicate between – and share data with – Telematics IVUs in a variety of different ways.” “It's possible, therefore, that each fatigue monitoring device may have its own way of interfacing with Telematics IVUs. “This lack of interoperability reduces the ability for transport operators and drivers to move seamlessly between the use of different devices and services – restricting flexibility and choice,” he added. “Telematics IVUs are a technology 'hub' in vehicles which integrate functions offered by other intelligent systems and devices – such as electronic user interfaces, dispatch systems, On-Board Mass (OBM) systems, and fatigue monitoring devices.” “TCA's work to provide fatigue monitoring device interoperability can be progressed

30 Highway Engineering Australia | June/July 2018

because of the availability of the National Telematics Framework – the governmentendorsed digital business platform for telematics and related intelligent technologies – which supports the availability of telematics applications with different levels of assurance,” he said. “Achieving interoperability between fatigue monitoring devices and telematics IVUs can be achieved by referencing common components of the National Telematics Framework, including the Telematics Data Dictionary, the Telematics Data Exchange and the common business rules of the Framework.” “In consultation with stakeholders, it is envisaged that an interface specification will be developed which offers standardisation and interoperability, providing a 'plug-and-play' approach,” Mr Corkill added. TCA will work with a diversity of stakeholders to progress this work, including providers of telematics devices and services, providers of fatigue monitoring devices, road and transport agencies, regulators and industry associations. The Victorian Transport Association Chief Executive Officer, Peter Anderson, said, “Technology has enormous potential to improve safety and reduce risk for heavy vehicle operators and road users in general.”

“The ability to provide drivers with notifications and warnings that they may be tiring through the use of technology and in-vehicle devices will significantly reduce fatigue-related incidents, and we applaud the work that TCA is doing to improve interconnectivity of fatigue monitoring devices,” Mr Anderson added. Ben Maguire, Chief Executive Officer of the Australian Trucking Association, welcomed the TCA’s support for increasing interoperability. “As an industry, we need technologies that will disrupt current thinking and empower drivers to manage their own fatigue. TCA’s work on interoperability will reduce the risk and cost of rolling out fatigue monitoring devices, and encourage their use,” Mr Maguire said. This initiative from TCA complements the National Transport Commission (NTC) Heavy Vehicle Driver Fatigue research project, which is being progressed in conjunction with the Alertness Cooperative Research Centre (CRC). “This is an important, strategic initiative to ensure an open, interoperable marketplace of devices, which minimises the barriers to the widespread adoption of fatigue monitoring devices,” Mr Corkill concluded.

TCA provides assurance in the use of telematics and related intelligent technologies. How TCA help the transport industry: • We connect both industry and government to telematics and related technologies • We check and approve technology to help transport operators make informed decisions • We provide information and advice on technological developments.

What we do: • Administer programs such as the Intelligent Access Program (IAP) • Type-approve In-Vehicle Units (IVUs) and On-Board Mass (OBM) systems • Data analysis and policy advice • Lead progress in connected / automated vehicles. .

TCA NEWS

TCA TO LEAD ENHANCEMENTS TO THE INTELLIGENT ACCESS PROGRAM (IAP) Transport Certification Australia (TCA) will lead work on developing a package of enhancements to the Intelligent Access Program (IAP), following the recent Transport and Infrastructure Council (TIC) meeting. As an application of the National Telematics Framework – the government-approved digital business platform for telematics and related intelligent technologies – the IAP enables road access and heavy vehicle productivity and safety reforms to be offered by road managers and regulators. Over 4,600 unique vehicles are currently enrolled in the IAP, with a net average of 55 additional vehicles (over the last year) joining the IAP application each month, to operate under one or more road access schemes offered by road managers across the country. Chris Koniditsiotis, Chief Executive of TCA, said, “Since becoming operational and available, the IAP (and the National Telematics Framework) has continued to be responsive to the needs of stakeholders, by focussing on performance outcomes and meeting the consumer demand for new and innovative technologies.” “The IAP application has enabled road managers to offer significant productivity reforms while offering transport operators competition and choice through an open technology market.” “Through our operational administration of the National Telematics Framework, TCA

has ongoing engagement with government, regulators, the telematics sector and the transport sector – to ensure the Framework (and each application) continues to meet the needs and expectations of stakeholders.” “Through these interactions, a number of significant enhancements have been identified which can improve the value, efficiency and affordability of the IAP,” said Mr Koniditsiotis. “We are pleased, therefore, that the National Transport Commission (NTC) has included – in one of its six recommendations from the Review of Regulatory Telematics – a recommendation dedicated to making enhancements to the IAP.” “We have also identified areas where transport operators may not be realising the full extent of benefits that come from the IAP being part of the National Telematics Framework. For example, many transport operators have been led to believe they need one device to participate in the IAP, and another device for other telematics functions – when in fact the National Telematics Framework has been designed specifically to allow the co-existence of applications through a single device and service.” “Yet the road transport industry has led the way, with 40,000 heavy vehicles across the country already fitted with a TCArecognised device. Applications available through the National Telematics Framework

(including the IAP) can simply be activated through these devices,” Mr Koniditsiotis said. Transport operators without a TCArecognised device are reminded that the Entry Options initiative remains available to them – at no cost. The Entry Options initiative allows TCA to assess existing systems used by transport operators for use in the IAP. Further information about Entry Options for transport operators is available here. TCA is now engaging with stakeholders to inform the development of a work program to enhance the IAP application, to present a business case with changes, enhancements and improvements to TIC by November 2018. TCA invites those wanting to contribute to the development of the work program to improve the IAP application, and/or offer feedback on the National Telematics Framework, please visit: www.tca.gov.au

TRENCHLESS TECHNOLOGY

INNOVATIVE PIPELINE RENEWAL by Paul Chalhoub, Products Manager, Downer PipeTech Project: Cement Lined Cast Iron DN450 Trunk Main Renewal Client: Water Corporation

Overview The need to rehabilitate watermains with trenchless technology has grown significantly over the past two decades in Australia. The growth has been fuelled by water authorities demanding solutions that not only deliver cost benefits, but also comply with key performance indicators around community, safety, environment, design life and returning the asset back to service. Water Corporation is the principal supplier of water, wastewater and drainage services throughout the state of Western Australia. Recently, Water Corporation has begun a renewal program known as ‘Pipes for Perth’, which proactively renews watermains across the metro area to improve the reliability of Perth’s water supply. Downer PipeTech was engaged to renew a 3.2km section of water trunk main, situated in a challenging urban area with high traffic volumes. The watermain to be renewed was a DN450 cement lined cast iron and due to the criticality and age of the main, Water Corporation decided to renew the asset. Furthermore, it was necessary to renew the pipeline with nominal flow capacity reduction to the original watermain. These requirements eliminated the conventional dig and relay method.

34 Highway Engineering Australia | June/July 2018

TRENCHLESS TECHNOLOGY

Downer PipeTech was able to successfully renew the watermain, by carefully removing the host pipe cement lining, allowing the insertion of a larger pipe. After the removal of the host pipe cement lining, Downer PipeTech installed a close fit PE DN400 pipe inside the existing trunk main. This methodology was a combination of descaling (removal of cement lining) and sliplining which minimised impact on the community and was a cost effective solution. The methodology worked well and the project was delivered successfully.

The Solution Downer PipeTech investigated a range of trenchless solutions to ensure that the most economic and suitable solutions was selected. The matrix shown above was used to help highlight the strengths and challenges of each technology option: Traditional Sliplining is the installation of a smaller pipe into a larger host pipe.

Conclusion Sliplining is primarily used for the renewal of pipes where the loss of flow capacity is not a major issue. However, on this project flow capacity reduction was not negotiable, so Downer PipeTech and their design team worked closely with Water Corporation, to adapt the most suitable trenchless solution that complies with the above needs.

Water Corporation was satisfied with the outcome of the project and Downer PipeTech will tender for future work with Water Corporation. Downer PipeTech is committed to offering its customers optimum solutions of the highest value for pipeline rehabilitation. For more information, please visit: www.itspipetech.com.au

CASE STUDY

FROM 3 HOURS TO 30 MINUTES THE MAGIC OF HONG KONG-ZHUHAI-MACAO BRIDGE Standing on a bridge above the Pearl River Delta in China, sandwiched between Hong Kong and Macau, Carl Pearse says it’s a magical feeling being a part of something so complex and grand. Pearse, regional manager-Asia Pacific, GCP Applied Technologies, watches as the final touches are completed on the Hong Kong-Zhuhai-Macao Bridge (HKZM Bridge). After seven years, the 55-kilometre bridge 20 times the length of San Francisco’s Golden Gate Bridge - is scheduled to open to traffic during 2018. “There was a lot of problem-solving required to protect the Hong Kong-ZhuhaiMacao Bridge from the surrounding elements and ensure its longevity,” Pearse said. “It’s a complex international project with many stakeholders, as well as technical and operational challenges, but it was such a pleasure to play a part in helping shorten the travel time between the three cities.” The HKZM Bridge, which will be among the world’s longest, is expected to cut travel times between Hong Kong and Zhuhai from three hours to just 30 minutes; further integrating the three cities in the Pearl River Delta and boosting the local economy. The HKZM Bridge is one of the first major projects in China to combine a bridge with a sea-crossing tunnel. The bridge consists of three cable-stayed sections and one undersea tunnel that spans the Lingding Ocean, a busy local shipping channel.

36 Highway Engineering Australia | June/July 2018

High stakes Constructing and waterproofing such a highprofile bridge is not without its challenges. Not only did the bridge deck waterproofing solution need to meet the strict construction and technical compliance of three government authorities (Mainland China, Hong Kong and Macau), complete stringent lab-testing, but the product also had to be available in large volumes and delivered within a tight deadline. After investigating several solutions and many types of materials, the Hong KongZhuhai-Macao Bridge Authority selected several waterproofing solutions from GCP Applied Technologies, including the ELIMINATOR® bridge deck waterproofing system (previously Stirling Lloyd, now GCP); ICE & WATER SHIELD® self-adhered roofing underlayment; PREPRUFE® pre-applied waterproofing membrane; and BITUTHENE® post-applied waterproofing. ADVA® concrete admixture from GCP was also used in the construction of the concrete portion of the bridge. “Ultimately, the Authority chose GCP as a partner because we have a proven track record at both the consultancy and supply level. Our bridge deck waterproofing solutions have appeared on many projects in the region, including the Tsing Ma Bridge and Stonecutters Bridge,” Pearse said. Waterproofing in high humidity areas can be challenging and time consuming

since some solutions require extended time before each coat can bond. However, with the ELIMINATOR® waterproofing membrane, it takes less than half an hour for each layer to cure. “The ELIMINATOR® product is very quick to install without the need for complex equipment and the unlimited open time helps reduce project time,” Pearse said. “The ELIMINATOR® product has been protecting high-profile bridges around the world in a wide range of challenging climatic conditions from extreme humidity and cold, to challenging marine environments for many years.” Instead of requiring expensive heater or spray machines, the ELIMINATOR® solution is applied using equipment that is simple to operate and affordable to purchase or replace. On the HKZM Bridge two coats of ELIMINATOR® waterproofing membrane were applied to three steel sections of the bridge. The first coat was a distinctive yellow followed by a second coat that is white. The cold-sprayapplied system is fast, effective and able to seal complex, critical details and penetrations with ease. The ELIMINATOR® system forms a tough, flexible and seamless membrane with no vulnerable joints, allowing it to perform throughout the design life of a structure and while simultaneously reducing maintenance costs. Its installation causes minimal disruption and it is capable of supporting traffic just an hour after application. The system allows for

wet film thickness gauge checks to ensure the specified film thickness is achieved across the area before curing. “The ELIMINATOR® bridge deck waterproofing range is protecting some of the world’s biggest bridges against corrosion and contributes to helping them achieve their predicted minimum design life of 120 years,” Pearse said. “The system is designed to provide superior protection from water, chloride and frost, and has four decades track record of success both globally and in Hong Kong. To date, over 40 million square metres of ELIMINATOR® waterproofing membrane has been applied globally, including in many areas of extreme climate.”

Bolstering against the elements While the ELIMINATOR® solution was selected for the deck, other parts of the bridge harnessed other GCP products. On the bridge’s boundary crossing facility in Hong Kong, for example, the Authority relied on ICE & WATER SHIELD® self-adhered roofing underlayment to protect the roof from the tropical rain that can sometimes turn torrential. “Hong Kong summertime temperatures under metal cladding can reach above 60 degrees Celsius, which causes sagging of rubberized asphalt in some other protective products,” said Robert AuYeung, Asia Pacific marketing director–Hong Kong, GCP Applied Technologies. “With ICE & WATER SHIELD® underlayments, the system’s nail seal-ability as well as dimensional stability provides excellent performance under high temperatures when applied under metal cladding.”

“The ELIMINATOR® product is very quick to install without the need for complex equipment and the unlimited open time helps reduce project time." ICE & WATER SHIELD® is a premier membrane composed of two waterproofing materials. First is an aggressive rubberized asphalt adhesive, and this is backed by a layer of slip-resistant, high–density, cross-laminated polyethylene film. To protect the adhesive quality of the product, it is backed with a foldless release paper. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. The Ripcord® feature embedded in the adhesive provides the applicator a “split release on demand” feature. On the tunnel running deep under the Lingding Ocean, the Authority selected PREPRUFE® pre-applied waterproofing membrane and BITUTHENE® post-applied waterproofing. These were used to safeguard

several tunnel passageways including at the Hong Kong boundary crossing facilities and staff subway section. “Because both the PREPRUFE® pre-applied membrane and BITUTHENE® post-applied waterproofing are fast to apply, they helped the HKZM Bridge keep to its tight completion schedule while the ease of application of both products helped ensure any human errors were minimized during placement,” AuYeung said. The PREPRUFE® and BITUTHENE® solutions can be used in several below-ground applications, including subway projects, to solve critical waterproofing issues. On top of this, both combine to block out water throughout construction of underground structures and tunnels.

CASE STUDY

On the concrete portion of the bridge, ADVA® high-range water-reducing admixtures from GCP were used to enhance the concrete’s durability. In addition to providing excellent water reduction, ADVA® admixture helps generate higher compressive strengths, better slump retention and improved rheology, which contributed to the high performance, underwater tremie concrete used in the bridge construction. From the soon-to-open HKZM Bridge to the Queensferry Crossing in the UK, GCP’s advanced range of bridge deck waterproofing solutions not only protect some of the world's largest bridges but also extend their lifespan. Pearse has worked on many of these bridge projects over his 20-year career. Reflecting on his most recent experience working on the HKZH Bridge, Pearse is almost nostalgic. “Standing on the bridge, in the middle of the ocean with no traffic, while watching Macao glimmering and the Hong Kong airport in the distance, I feel so privileged to be part of a project that will hopefully boost the economy in the Pearl River Delta,” he said.

FOCUS ON ASPHALT

40 Highway Engineering Australia | June/July 2018

FOCUS ON ASPHALT

MARINI Top Tower Range:

Focus on ecology and recycling The MARINI Top Tower plant is fitted out with the latest generation devices to satisfy the requirements of ecology and recycling (waste absence --> circular economy). ECOLOGY • Blending into the surrounding environment: acoustic reduction and visual harmony; • Ample reduction in gas emissions to comply with the toughest legal limits; • Management and treatment of emissions (patented), which are fed through a tunnel to the discharge of the mixer and storage bin.

Fumes collection

Ecology

Asphalt production sites impact the environment with two types of emissions: 1. Conveyed emissions: caused by the drying and mixing phases; 2. Diffuse emissions: generated during loading and unloading the materials and during other secondary stages of plant operations. In order to further reduce the diffuse emissions, special exhaust systems can be fitted to convey the emissions into the stack, the site’s single exhaust point. To make the exhaust effective, it must be effected at the moment the fumes are generated and as near as possible to the emission points, special care being taken to limit the exhaust area and protect it from external air flow. The vapours exhausted from the bitumen tanks and those generated during asphalt discharge onto trucks can be collected and treated through special collection systems.

Cleaning systems and fumes treatment For eliminating the polluting emissions and odours produced by the plant, a capturing system for diffuse emissions is provided at the discharge points at the truck, skip and mixer, together with an oil separating filter. Finally a further phase can be added which involves the heating of the fumes by feeding them into the hottest part of the plant i.e. the dryer burner. The technical solution that MARINI proposes is covered by International patent and can boast surprising results. And it’s hardly surprising that the system bears the name ZEROVOC. Recycling

4 DIFFERENT SOLUTIONS • Recycling into the recycling ring standard solution: up to 35% special MARINI Evo DRYER series to recycle more than 35% • Recycling into the mixer up to 40% • Combined system ring + mixer up to 60% • Parallel drum up to 90%

RECYCLING Over the years there has been a growing interest in the use of recycling. Throughout the world the trend for professionals to work towards an increase in: • Reuse of raw materials: the lack of aggregates due to the reduction in quarries operating at both national and international level; • Energy savings: energy consumption is lowered due to the reduction in aggregate quarrying, transportation and traffic delays; • Bitumen recycling: not just aggregates are recycled, but also, and above all, the bitumen binder contained in the RAP.

NATIONAL PRECAST FEATURE

100-YEAR DURABILITY UNDERPINS AUSTRALIA’S LARGEST REGIONAL INFRASTRUCTURE PROJECT PROJECT: PACIFIC HIGHWAY UPGRADE – WOOLGOOLGA TO BALLINA (W2B) STAGE 4 PRECASTER: REINFORCED CONCRETE PIPES AUSTRALIA (QLD) CLIENT: BGC CONTRACTING CONTRACTOR: PACIFIC COMPLETE CONSORTIUM (LAING O’ROURKE & PARSONS BRINKERHOFF JOINT VENTURE) ENGINEER: GHD Lying beneath Stage 4 of Australia’s largest regional infrastructure project is a stormwater solution that will deliver more than 100 years of strength and durability. The Woolgoolga to Ballina (W2B) project involves the duplication of 155 kilometres of the Pacific Highway to a four-lane divided road in New South Wales. When complete, the $4.3 billion upgrade will improve travel reliability through better flood immunity, reduce crash rates by an estimated 27 per cent, and provide more readily-available alternative routes and 170 new bridges. Stage 4 of the project is the $100 million upgrade of a 13-kilometre section of the Pacific Highway between Tyndale and Maclean.

42 Highway Engineering Australia | June/July 2018

A vital phase in the larger project, it is being constructed by BGC Contracting and consists of stormwater drainage works as well as bulk earthworks, road and pavement construction, bridge construction and finishing works. Vital to the project’s success are 10 kilometres of steel reinforced precast concrete pipes manufactured by National Precast member, Reinforced Concrete Pipes Australia (RCPA).

“This pipe manufacturing technology is multiple times faster than traditional methods and offers the customer a more cost-effective product which can be virtually made to order,” Mr Alexander explains. “This minimises lead times for contractors, who often experience design changes based on site conditions as construction progresses.”

LONGEVITY WITH PRECAST

With a geographical distance of almost 250 kilometres between the precaster’s Queensland manufacturing site and the project location in New South Wales, it’s not only the speed of manufacturing that is important in a project such as this. Getting the logistics right is critical to ensuring a smooth, on time delivery of the precast elements. “RCPA’s careful management of transport demands has meant that the client has not experienced any significant delays with pipe supply,” Mr Alexander says.

According to RCPA’s Account Manager, Graham Alexander, opting for a precast solution assures long-term strength and durability. “There is a proven history of performance from steel reinforced concrete pipes, achieving a 100-year design life,” Mr Alexander details. The precaster is supplying more than 5,000 tonnes of pipes ranging from DN375mm to DN1800mm in size. All pipes feature rubber ring joints and approximately half have additional concrete cover to meet marine exposure requirements.

MANUFACTURING EFFICIENCIES

The pipes are manufactured with dense, high-quality concrete and are vertically cast in RCPA’s bi-directional machines.

LOGISTICS KEY TO PROGRAM

The Woolgoolga to Ballina project is being delivered is in partnership with the New South Wales Government. The project team has been carrying out earthworks between Tyndale and Maclean since mid-2016. Major works will continue for approximately 22 months, weather permitting.

NeTC CONFERENCE WRAP-UP

AUSTRALIAN AND GLOBAL TOLLING LEADERS HAVE GATHERED FOR 2 DAYS TO TACKLE CHALLENGES IN KEEPING TRANSPORT MOVING. The NeTC conference, now in its 13th year, is proving to remain as relevant today as when it was created in 2006. Whilst the topics have progressed to include in 2018 how Connected and Automated Vehicles (CAVs) might interact with toll road infrastructure, the challenges of keeping transport moving remain top of the agenda. The emergence of increasingly connected and automated vehicles is expected to lead to fundamental changes to roads, transport and cities in the future. The industry is talking these challenges and the changes in the flow of vehicles on the roads to more easily accommodate all journeys. Changes are being made now to make a difference to travellers’ experiences in the nearterm. With an ever-increasing demand for road journeys, ways are being sought to convey growing populations to their everyday destinations – often a city-centre, or crosscity location. Other approaches are looking to minimise the impact of heavy vehicles and freight on the roads, to keep heavy vehicles and freight to the main arterial roads, and away from local streets. To support population and congestion increases, particularly in inner-city suburbs, large, exciting infrastructure projects are under development to move traffic away from local roads more quickly.

46 Highway Engineering Australia | June/July 2018

In NSW, WestConnex is one such project which, whilst widening and extending the M4 motorway and connecting it to the M5, will result in a 9km tunnel – an Australian first! Another progressive infrastructure project is the regional Toowoomba Second Range Crossing toll road. This 41km road is the largest regional toll road project in Queensland’s history. Scheduled to be completed in 2019, the second range crossing will take heavy and super-heavy highway traffic around north of Toowoomba rather than through it. This project aims to reduce road and driver safety, reduce travel time and increase freight efficiencies. NeTC2018 conference attendees also heard updates from international speakers including Q-Free ASA Chief Technologist, Knut Evensen who noted that “Australia is amongst the leaders in standards and deployments in connected vehicle infrastructure. Whilst urban ITS is a quickly growing field with strong links to Smart Cities, Automated Mobility and Big Data, there is a need for standards to be developed to ensure future road tolling technology will be one of the primary toolkits to achieve the needs of future smart cities mobility”. Telematics technology is also again featuring as a hot topic with proof of concept activity investigating toll road use and identify potential toll road solutions for heavy vehicles freight.

Tom Walker, CEO Cubic Transportation, which was the major sponsor at NeTC2018, said: “The National Electronic Tolling Conference provides an exciting opportunity for government, industry and academia to share their knowledge, form partnerships and discuss new technologies that could help overcome current and future transport challenges.” “Transport serves us best when all modes are connected. With multi-modal transportation at the core of future mobility services, tolling needs to become part of the wider mobility as a service trend. This offers an exciting opportunity for tolling agencies to appeal to a wider number of commuters who may not typically consider a toll roads part of their journey,” he added. Susan Harris, CEO ITS Australia said: “NeTC2018 has again exceeded our expectations in terms of forward thinking, transport technology related activities. There were many insightful presentations by our speakers and we’re looking forward to seeing the next wave of infrastructure projects in this arena.” “The NeTC conference is a forum for all areas of industry to meet and talk about how the future of road infrastructure will interact with many areas of transport technology, and how the industry will keep transport moving in times of increased road use. To help this aim, we will continue to host this conference for the leaders in this space,” she concluded.

CUBIC SELECTED TO PROVIDE

QUEENSLAND’S NEW TICKETING SYSTEM CUBIC TRANSPORTATION SYSTEMS EXPANDS FOOTPRINT IN AUSTRALIA WITH FIRST SYSTEM-WIDE DEPLOYMENT OF ADVANCED TICKETING AND PAYMENT TECHNOLOGIES. ITS Australia member, Cubic Transportation Systems has been awarded the contract to design, build and operate the new ticketing system as part of Queensland’s $371 million investment in ticketing. Cubic will be responsible for upgrading the current system to incorporate some of the world’s most advanced ticketing technologies including contactless payment, and next generation real time passenger information. Operation and maintenance of the system are also included in the agreement. The new system will enable Queensland commuters to use bankcards, mobile phones and personal electronic devices including watches to pay for travel on public transport. Queensland’s Minister for Transport and Main Roads, Mark Bailey said this was an exciting partnership that would provide Queenslanders with one of the most advanced, flexible and secure public transport payment systems in the world. “This payment solution will bring more convenience and freedom of choice for commuters,” said Minister Bailey. “We’re delighted that proven technology already used across London, Chicago and Vancouver will be further enhanced for the benefit of Queensland commuters.” Importantly, regional Queensland will not be left behind, with current go card operator Cubic, due to deliver the new system in 18 regional areas, as well as the metropolitan south east, after being selected as the successful tenderer following a competitive global procurement process. Transport and Main Roads Minister Mark Bailey said the Queensland Government had allocated $371.1 million to roll out the system

including new readers, quicker fare gates and system equipment, an updated app platform, realtime and new ticketing equipment on urban buses. “The new ticketing system is an exciting chance to expand our ticketing options and to give public transport customers more flexibility, and in this year alone we have allocated nearly $90 million to get this project underway,” he said. “This is a new, hi-tech system that will make it easier for all Queenslanders from Cairns to Coolangatta to catch public transport,” Mr Bailey said. “Customers will still be able to keep using both go cards and paper tickets once the new system is implemented, ultimately offering even more ways to conveniently pay for public transport.” “go card has served SEQ commuters well for the last decade but we are now delivering a payment evolution offering more flexibility, increased accessibility and security. “Having a more convenient payment system will also encourage more people to use public transport,” the Minister said. Brad Feldmann, chairman, president and chief executive officer of Cubic Corporation, said the Queensland contract award was a testament to Cubic’s commitment in revolutionising fare payment systems. “We look forward to leveraging our worldclass technologies to deliver a system that will improve travellers’ daily commutes.” “This next-generation ticketing system to be installed by Cubic will provide Queensland commuters with more options and greater payment flexibility in how to pay their fares,” said Matt Cole, president of Cubic Transportation Systems.

“Riders want speed, convenience and a more efficient travel experience. The NGTS will deliver just that.” The system also provides future flexibility to add other transport modes and payment options. The Minister pointed out that the new system would also include additional encrypted bank grade security and privacy protection for commuters. “We’ll also be introducing a state-wide payment system rather than just SEQ alone, including on urban buses in 18 different regional areas where qconnect services run. “This means that for the first time, commuters and tourists in those regional areas will have integrated ticketing – making public transport easier and hopefully helping to boost regional tourism. “It will also mean that we will be able to deliver real time tracking for the first time in regional areas. “The system will of course need to be designed, built and tested before trials are launched.” Customers will be able to set up an account via a new app or web platform and have the choice of several payment methods — including go card and paper tickets. They will also be able to use major contactless credit and bank cards without the need to set up an account. “I want to reassure people that they will still be able to continue to buy paper tickets and use their go cards under this new system,” Mr Bailey said. “The system will give them the choice to use the payment method that is most convenient and comfortable for them.” The project will be delivered in the next four years. Detailed design, development and implementation planning will be undertaken first and this will establish the exact rollout timeframes. The 18 regional areas include: Cairns, Innisfail, Townsville and Magnetic Island, Bowen, Airlie Beach and Proserpine, Mackay, Yeppoon, Rockhampton, Gladstone, Bundaberg, Maryborough, Hervey Bay, Gympie, Sunshine Coast hinterland, North Stradbroke Island, Kilcoy/Woodford to Caboolture, Toowoomba and Warwick.

THE PREMIER OF SELF-DRIVING BUSES

IN GOTHENBURG The first self-driving bus is now rolling in Gothenburg, Sweden. The inaugural journey took place during May at the Chalmers University of Technology campus in Johanneberg. The autonomous shuttle bus is available to the public, moving people between the main entrance of Chalmers University of Technology, Johanneberg Science Park, and the Chalmers Library. "We intend to demonstrate that self-driving vehicles are both safe and comfortable," says Anne Rosa Simonsen, the communications manager at Autonomous Mobility, the company that is responsible for the shuttle operation. “Getting started in real traffic is like a lunar landing for us!” The project is the second of its kind in Scandinavia. Behind this venture is a partnership between fifteen organizations and companies related to mobility, urban planning and transport. Birger Löfgren at the research institute RISE Viktoria is the one who leads the work. "These small, self-driving buses are a completely new type of vehicle - which creates opportunities we did not think previously existed,"

he says. “They can help us understand how cities of the future can develop, with reducing private car ownership and creating more efficient transportation, especially where people are sharing rides.” After the four-week trial in the Chalmers area, the project moved in the autumn to Lindholmen Science Park, the growing innovation cluster in Gothenburg, where a large part of Sweden's vehicle technology development is taking place. The project will continue there for a six-month period. The bus-project in Gothenburg is a part of the Government’s innovation partnership program, “The next generation’s travel and transport,” and is funded in part by Vinnova through Drive Sweden. "This is an important, collaborative project where business, academia and public actors join forces," says Birger Löfgren. “During the test period, we will conduct research on technology and user acceptance that will be used to assess the potential of self-driving vehicle technology.” The Arma model shuttles are manufactured by Navya, and are set to operate at a maximum velocity in Gothenburg of 20 km/h.

The shuttle can carry a total of 11 seated passengers, including an on-board representative of the operating company, who is there to answer questions and manage technical situations during the project Weighig in at 2,400 kg and measuring some 4.75 metres in length, 2.11 metres wide and 2.65 metres in height, the shuttle can travel approximately 100km, or operated for 8 hours on one charge. The shuttle buses are fully electric and therefore are local emission free. The Navya Arma model shuttles also currently operate in France, USA, Switzerland, and Australia.

ACA CORROSION FEATURE

INDUSTRIAL COATINGS FOR STEEL STRUCTURES Owners and operators of high-value assets need to understand the cost implications of ignoring the effects of corrosion that poses a threat to all infrastructure through the degradation of structures such as buildings, roads, bridges, pipelines and towers. The economic impact of corrosion represents an annual cost of many billions of dollars to the economy. Some of the advantages of planning for corrosion control and mitigation at the design phase include extending the life of an asset thus making it more profitable - and reducing maintenance time and costs thereby increasing an asset's utilisation. According to Craig Ross, Director of Napier Sandblasting (NSB) in New Zealand, some construction contractors sought to save money on infrastructure projects by using substandard coatings with the result that some buildings, towers and bridges are already showing signs of fatigue and distress. “While the majority of the cowboy coatings applicators that applied poor coating systems have gone, many of their structures already require remediation,” he said. “Luckily changes in regulations and better enforcement of standards means that new designs should have a much longer operational life.” Justin Rigby, coatings consultant at Remedy Asset Protection, added that steel structures within industrial facilities are usually located in 'aggressive' environments. “Domestic steel buildings do not face the same stresses as offshore or maritime structures,” he said. “Owners of offshore platforms or dock cranes exposed to the marine environment cannot afford for corrosion to degrade their assets.”

52 Highway Engineering Australia | June/July 2018

“Coastal and maritime areas are harsh and corrosive environments for all structures, but more so for steel ones,” Ross added. Rigby stated the best way to protect an asset from corrosion is to select a corrosion resistant metal or to apply a protective coating as a barrier to separate the structural steel from the corrosive parts of the environment, such as moisture, oxygen and pollutants. Ross added that even relatively non-reactive stainless steel requires protection in certain situations. “NSB does a lot of work in the hide tanning industry and other really severe environments, generally where acid attack or abrasion is an issue,” he said. Cathodic protection is one technology that can be used to impress a current into a structure to alter the surface reactive characteristics of a metal to minimise corrosion. According to Rigby, it is important that a protective coating project is carefully planned. Protective coatings projects are usually unsuccessful for relatively simple reasons. Planners often do not fully comprehend the technical complexity of many coatings projects, especially if the coating is to be applied to an existing steel structure; even more so if the site is in a remote location. As a consequence, they fail to invest the time and resources to manage it effectively which results in substantial cost implications when things go wrong. Protective coatings are not just paint. Coatings are engineered products that undergo rigorous testing and refinement to provide specific properties that will protect a structure from its service environment. “The most important considerations are the operating environment and choice of the appropriate coating,” Rigby added. “A simplistic

analogy would be that a structure is plastic coated.” There is a wide selection of coating products available to the market so it is essential that the appropriate coatings system is chosen. There is no single product that meets every coating situation as the desired attributes may be mutually exclusive; so during the planning of a project, a compromise may need to be made, but is important to not be fooled by a 'one size fits all' approach made by some manufacturers. Modern technology has developed active pigments which are being incorporated into primers to provide additional protection. Active anticorrosive pigments are added to primers which can give further protection for areas with coating damage in addition to their barrier effect. These pigments prevent corrosion of a metal substrate by building up permanently passive conditions at the metal surface and/ or by a build-up of solid compounds which fill the damaged area of the coating. It is important to be flexible and adaptable when developing protective coating projects. While identifying areas of risk at the start of a project is an extra expense, it will help ensure a project's success. Managed well, a protective coatings project can provide owners with great outcomes. The Australasian Corrosion Association (ACA) works with companies like Remedy and NSB, along with academia, to research all aspects of corrosion in order to provide an extensive knowledge base that supports best practice in corrosion management, thereby ensuring all impacts of corrosion are responsibly managed, the environment is protected, public safety enhanced and economies improved. “The quality of the finished project is dependent on how skillfully and effectively a coating is applied,” Rigby said.

The technicians chosen to apply a coating must have the appropriate skills. Obvious selection criteria are experience with the protective material and the equipment used to apply it to a structure. A less obvious criterion, especially for any sort of tower structure, is abseiling skills; technicians might have to be in a harness and suspended in mid-air which requires a particular mix of physical and psychological attributes. There are many standards relating to the application of protective surface coatings but sometimes compromises may need to be made. When planning protective coatings, it is important to take account of factors such as the geography, access to the structure and climate, all of which impact the cost of the project. According to Rigby, there are a range of quality tests available that comply with Australian and international standards, many of which are covered in the ACA's NACE Inspector courses. A good coating specification will reference AS/NZS 2312:2014 â&#x20AC;&#x153;Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatingsâ&#x20AC;? as a minimum and categorise the service environment according to its corrosivity and then nominate a coating system based on the desired design life of the coating. One vital aspect of coatings projects is to have certification that the job complies with all the appropriate legislation, regulations and standards. There are two ways to achieve this; to pay for third party inspection and engage a contracting firm that has a PCCP accreditation. This ensures they have staff with the necessary skills and accredited processes, providing peace of mind to customers that quality is 'built in' throughout project planning and execution.

The cost to coat a structure with an appropriate and effective protective material varies depending on whether it is applied in a workshop or on-site and averages between $80 and $300 per square metre. “This is a relatively minor cost, compared to the cost of not coating the steel,” said Ross. “However, cost is very much relative to what the required durability expectation is, the level of aesthetics required and how harsh the environment is.” If a structure to be protected is in a remote location, it will be necessary to select the most cost-effective means of transporting

materials and personnel to the site. Additionally, remote sites may be exposed to climatic extremes which impact on applying a coating. For example, monsoonal rains in tropical regions would make it difficult to spray a coating on to any type of structure. The health and safety analysis of a project must look at how to effectively protect a structure and address any environmental considerations. It must also consider how to properly apply the coating to minimise its effects on the surrounding areas as well as protect the technician who might be working in a harness tethered metres above the ground.
